00:08It was very quickly apparent that this was a powerful earthquake, and was growing in power.
00:23It was terrifying in the moment, seeing all the devastating power of the earthquake.
00:40The news on the radio was talking about the Fukushima reactor.
00:44They said there's been an explosion at the nuclear plant, turn the car around and drive south.
00:56It was sort of a Chernobyl moment.
01:12If this were to be a really significant release of radio activity, would you have to evacuate Tokyo?
01:38On the 11th of March 2011, the largest tsunami to hit Japan for more than a thousand years devastated the
01:47equator.
01:47On the east coast, leaving thousands dead or missing.
01:54But few knew that another emergency was brewing at the Fukushima Daiichi nuclear power plant.
02:06Professor Kuzuto Suzuki investigated the crisis.
02:10Fukushima Daiichi had six reactors, and four of them were located in coastal lines.
02:18After the earthquake, three operating reactors immediately shut down.
02:24So once the reactor was shut down, it was considered safe.
02:33But the tsunami breached the reactor buildings, leaving the power plant without power.
02:40Professor Tom Scott helped with the disaster clear-up.
02:44Part of the damage that was caused by the tsunami, pumping systems were disabled.
02:52The problem with light water reactors is that even though you may shut down and stop causing fission,
02:59the fuel, the fuel will generate lots of residual heat.
03:02And it's essential that once you've turned off a reactor that you continue to take away this residual heat.
03:10And if you fail to do so, the reactor core will get hotter and hotter and hotter.
03:19So the plant needed electricity and for an extended period it couldn't get it.
03:27It couldn't keep those key parts cool.
03:29And that's when the crisis was turning into a potential disaster.
03:38The power company and its workers scrambled to avert a nuclear meltdown.
03:45It was very difficult to bring in off-site emergency response capability
03:51because of the debris and destruction caused by the tsunami because roads were physically broken.
03:57So very much it was a situation that the power plant and the people on the power plant
04:01were volunteering to go into the plants to turn off key valves
04:05or to try and open key valves in some instances
04:08to try and make sure that they could keep cooling those reactor cores.
04:11Those were very, very brave people.
04:13It was a moment when there were difficulties because of the lack of light and everything.
04:20So there was no way that the Fukushima Daiichi will restart the cooling system
04:28and therefore the fuels are starting to melt down.
04:38We had a situation where the fuel elements started to get very, very hot,
04:42started to generate steam and we got a sort of runaway steam corrosion.
04:47What that meant is that lots of hydrogen was quickly produced
04:51and it started to fill the insides of the building.
04:55The release of hydrogen from the reactors made a very combustious mixture in the reactor halls
05:03of the wider building around them.
05:04Temperature started to rise and the clot began to tick.
05:11The government declared a nuclear emergency.
05:16But in the chaos after the tsunami, many were unaware of the crisis at the plant,
05:22including some who fled inland for Tsushima district with Mizuei Kano to her centuries-old farmhouse.
05:30There were many people who came to Tsushima and came to the hospital.
05:35There were many friends who were friends who were the same apartment.
05:41There were 25 people who were connected to the hospital.
05:46There were also people who were in the hospital.
05:48There were people who were in the hospital.
05:54There were people who were in the hospital.
05:57Meanwhile, across Japan, thousands were still waiting for news of loved ones caught up in the tsunami.
06:04Like Kazuma Obara, now a photojournalist.
06:10In 2011, I was in Kyoto and I worked as a salesperson and financial company.
06:18My best friend's hometown is Minami-sanori town.
06:23It's really closed in Miyagi prefecture.
06:27It's like second hometown for me.
06:32I asked him, how was your parents?
06:35And then he just answered.
06:39The phone was dead, so he couldn't know if they are okay or not.
06:45I totally felt I'm powerless, but I wanted to do something.
06:52You know, I was in Osaka, so I could buy almost everything, like fuel, food, water.
07:00So I bought the surprise for the disaster area, and I picked up my best friends in Tokyo.
07:07And slowly and slowly, I moved to the north.
07:16Financial Times bureau chief Muir Dickey was already reporting from the area.
07:22Looking around, it's almost impossible to believe that this was a bustling seaside town.
07:27Until that wall of water smashed through, turning the wooden houses into matchsticks.
07:33I don't think anything prepared me for the kind of scenes that I saw when we finally made it to
07:44the actual coast.
07:47And this absolute devastation of towns and cities along it.
08:05No doubt in a lot of trees, it sounded so sad.
08:09It sounded so small, and it sounded like a big offensive sound.
08:09From the distance from the outside, we made a strong sound.
08:10Butโ€ฆ
08:10The all of us didn't know what happened, who was still going for.
08:19A small spark will create the hydrogen power to create the hydrogen power to create,
08:29The hydrogen explosion basically blew out the building, and this creates the visual impact
08:39that it was sort of a Chernobyl moment.
08:44I got a message from my editors in Hong Kong saying there's been an explosion at the plant.
08:51And that was the first time I realized that this was more than just worry about a nuclear plant,
08:58that it was something very, very serious.
09:04Plant worker Yukio Shirahige had fled home after the tsunami and saw the explosion on TV.
09:11So, 1ๅทๆฉŸใŒ็ˆ†็™บใ—ใŸใฎใ‚’่ฆ‹ใŸๆ™‚ใซใฏใงใ™ใญใ€ใ‚‚ใ†ใ“ใ‚Œใฏๅคงๅค‰ใชใ“ใจใซใชใฃใŸใฃใฆใ„ใ†ใตใ†ใซๆ€ใ„ใพใ—ใŸใ€‚

09:49Because within that explosion, the heat that's released,
09:53you release radioactive material up into the atmosphere.
09:57But at the same time, there was very little information about the spread of radioactivity.
10:03And part of the reason for that is this site had 24 static monitors for measuring radiation.
10:09But the tsunami took out 23 of those 24.
10:14At her farmhouse, Mizue Kano didn't yet know the source of the explosion.ใงใ‚‚ใใฎๆ™‚ใญใ€็ฉบๆฐ—ใŒ้‡‘ๅฑžใฎๅ‘ณใŒใ—ใฆใŸใ‚“ใงใ™ใ€‚ๅฎ‰ใ„ใ‚นใƒ—ใƒผใƒณใ‚’ๅฃใซ่ˆใ‚ใŸใ‚ˆใ†ใชใ€‚็ฉบๆฐ—ใŒใ‚†ใ‚‰ใฃใจใ—ใฆๅ…‰ใ‚‹ใ€‚

12:14News of the explosion at Fukushima Daiichi spread around the world,
12:19but there was little information about the radiation risks for those on the ground.
12:27Everybody knew there was a very serious crisis at the plant,
12:31and the population was watching anxiously the updates from the government.
12:41But I think it was clear at times that the government itself was struggling to understand the situation about what
12:47was happening in the plant.
12:51Assurances that such a thing could never happen in the first place had been shown not to be warranted.
12:58So there was a great deal of confusion, a great deal of doubt, and a great deal of concern.
13:09The government ordered an evacuation for 20 kilometers around the plant.
13:15But in Tsushima district, Mizuei Kano was 10 kilometers beyond the zone, when she had unexpected visitors.
13:27She was a bad idea of what she was doing at the time.
13:35She was a great deal of confusion.
13:44She got a lot of confusion about it.
13:48She was a big deal of confusion, and she was like,
13:52and she said,
13:55She was just a sigh.
13:56We were just hungry.
13:59Mizue had no idea who the people were,
14:02but she was scared,
14:04as were her neighbors.
14:06They were able to get them to the land for the people's,
14:10and they were looking for the land.
14:14She was looking for them to be able to get them for the land.
14:15We had them only for the land.
14:15I was able to take a coat of clothes, and I couldn't find it anymore.
14:21So I made a place for a dog, and I ran away.
14:29While thousands packed up and left, some feared the radiation could be blown south to Tokyo,
14:36triggering deadly stampedes as 30 million people tried to flee.
14:42If this were to be a really, really significant release of radioactivity,
14:46were those people genuinely in lots of danger?
14:49Would you have to evacuate Tokyo?
14:53People were scared. The Prime Minister was scared.
14:57We discovered later that the Prime Minister himself had started to think about the need to evacuate Tokyo,
15:08which in itself would have caused huge loss of life.
15:14The Prime Minister was thinking in those terms that this could turn into an extraordinary disaster.
15:26Fear of radiation continued to spread.
15:29And 100 kilometres north of the plant, the news reached communities hardest hit by the tsunami.
15:39People in the area, including in the disaster zone, were desperate to know what was happening at the plant,
15:47and also desperate to know what it meant.
15:52Richard Halberstadt was sheltering at Ishinomaki University.
15:58I ended up spending two nights just sleeping at the university with many of the other staff.
16:06Our main way of getting news from outside was using battery-driven radios.
16:12And so, of course, the news on the radio was talking about the Fukushima reactor.
16:20We knew when it was broadcast that there had been an explosion and so on, which was concerning for us.
16:27But ironically, not as concerning as maybe for other people,
16:32because we were so busy trying to look after ourselves from the earthquake and tsunami damage.
16:42Just north of Ishinomaki in Minamisan Riku, Kazuma Obara arrived to help search for his friend's relatives
16:50and reveal the devastation to the world.
16:54Since I was 16 years old, I wanted to be a photographer.
17:00I wanted to shoot. I wanted to document.
17:06There were 30 housing before the tsunami.
17:12When we arrived at the town, only two housing were still there.
17:18And my friend's house wasn't there.
17:25From the basement, everything was moved to somewhere.
17:30So, when my best friend saw that situation, he wasn't stopped crying.
17:41Hey.
17:44Hi.
17:50His grandfather was missing.
17:53And what he could do for him was just visiting the place where someone saw the grandfather at the last
18:08moment before the tsunami came.
18:10And he was just crying.
18:16And told something to his grandfather.
18:21My father.
18:24I couldn't do anything for him.
18:26And I was just shooting.
18:28I was just shooting.
18:38The kind of level of trauma, the wave of trauma and distress that came in with the tsunami is hard
18:47to describe.
18:48But as a journalist, what you have to do is try to describe it.
18:51What you have to do is try to understand what happened and communicate it to the outside world.
18:57Soldiers, doctors, firemen, other relief groups are all working hard to try and bring some kind of semblance of normality
19:04back to people's lives.
19:05But just walking around this town is to sense the scale of the challenge.
19:15A friend came to find me partly to check that I was alive and also he gave me information which
19:26included the fact that one of our best friends had lost his life.
19:31Everything was so surreal and so completely removed from everyday life that I really didn't have a chance to kind
19:41of think about how I felt about anything.
19:44One of our other really good friends, who is a hotel owner, had converted the hotel into an evacuation shelter.
19:52And so my friend suggested that we go and meet him.
19:56So that's what I did.
20:00We had no electricity, no water, no gas, and it was cold because March is very, very cold in this
20:10area.
20:12So wearing all the clothes that we had 24 hours a day, huddling around little kerosene stoves and like shivering
20:21in bedclothes at night.
20:29Meanwhile, Ryoko Endo was stranded at Ishinomaki City Hall, believing her three children were sheltering across town at their school
20:38gymnasium.
21:07All of our friends were tentative.
21:09I think I was able to keep my mind.
21:12If my kids are in the gym,
21:17I would like to go to school.
21:20I didn't think that much.
21:32100 km south at Fukushima Daiichi,
21:36after the explosion at Unit 1,
21:38workers were also trying to cool nuclear fuel
21:41in Units 2, 3 and 4.
21:47You have a series of reactors that are in trouble,
21:50but one of them blows up.
21:52Then your teams that are trying to work on the other reactor buildings
21:57are withdrawn because of the danger,
22:00and that made it very, very challenging
22:02to try and prevent similar hydrogen explosions in those other reactors.
22:09The key thing was to deliver cooling water
22:12to the parts of the plant that were getting too hot,
22:16and they tried various ways of doing that.
22:21The initial priority was just restoring electricity supply.
22:26They found, in fact, at one point,
22:28the plug and socket didn't fit for an emergency supply.
22:33Around 11am on the 14th of March,
22:37a second explosion blew the roof off reactor building 3.
22:42On the 15th, there were two further explosions.
22:47Effectively, it was the same mechanism each time.
22:50Build-up of hydrogen followed by an explosion,
22:53starting with Unit 1 and then with other units as well.
22:58The fourth reactor, which was not in operation,
23:02was also blown away because the hydrogen was leaked
23:07into the building of the fourth reactor
23:10because the third and fourth are connected.
23:17Three reactor buildings were now open to the elements,
23:20risking further radiation leaks into the atmosphere
23:23from the reactors or the spent fuel.
23:28Not only is there a requirement to keep the reactor core cooled,
23:33but there's also a requirement to keep the spent fuel ponds
23:36filled up with water and to keep the fuel cool in that as well.
23:41The spent fuel pools were on the high floors of the reactor.
23:48So when the steam explosion happened,
23:52then the spent fuel pool was also exposed to the air.
23:58If there was no cooling system,
24:01there'll be a meltdown of the spent fuel.
24:04It could cause fires among the uranium spent fuel
24:08with the potential for very large releases of radiation.
24:19The explosions that tore open Fukushima Daiichi's reactor buildings
24:24unexpectedly helped with the effort to cool overheating fuel,
24:29but at a huge cost.
24:33So what happened in the end was they were able to bring in military firefighting vehicles
24:40that could deliver large amounts of water into the cooling pond,
24:44and they were also able to flood the lower reactor areas with water.
24:51That averted the possibility for a much bigger disaster,
24:56but it also created this problem of lots and lots of radioactive contaminated water.
25:05The reactors had lost their integrity,
25:08so you can imagine each reactor core being like a broken teacup.
25:13You can keep pouring water into the top of the teacup,
25:16but the crack at the bottom will keep allowing water to flow out.
25:20So what that meant is,
25:22is as they continued to put water through the reactor cores,
25:25they produced more and more radioactively contaminated water
25:28that was physically draining to ground or they were having to pump out.
25:34The threat of explosions had passed,
25:37but workers at the plant still risked radiation exposure.
25:42Meanwhile, evacuees like Mizuei Kano were facing a trauma of their own,
25:47the stigma of contamination.
26:11It's a really painful moment.
26:14There are jobs, there are houses, there are birthplaces.
26:18These are all gone.
26:21So there are a lot of scars in the society by this incident.
26:27Many living beyond the 20km exclusion zone sheltered in their homes.
26:33One thing that I found quite harrowing actually was,
26:37for the people that had been displaced,
26:40they'd been displaced, they'd been moved away.
26:42But the people that lived just outside the exclusion zone,
26:46demonstrably sometimes they received more radioactive fallout
26:49than people inside the fallout zone,
26:50and yet they hadn't been relocated.
26:53Despite the risks, plant workers who had been evacuated days earlier
26:58were recalled to try and prevent further spread of radiation,
27:03including Yukio Shirahige,
27:05who supported the mission to cover Reactor Building 1.
27:30C377-0.
27:38C387-7.
28:01Kizuma O'bara arrived in the exclusion zone.
28:08When I was a high school student, I already started having the interest to the nuclear industry, so I wanted
28:19to do something with Fukushima.
28:23No media could go into the nuclear power plant and ask the workers what was the condition.
28:31A contact helped Kizuma gain entry to the plant.
28:35So I was afraid, but I decided to visit only one day, so I thought maybe it's okay.
28:44Most of the workers lived surrounding the area of nuclear power plant before the accident, but they had to evacuate
28:53it from the zone.
28:54So many of the workers I met lived in temporary housing, and they went to nuclear power plant from temporary
29:03housing.
29:04That is so hard.
29:56It was so hard to see the worker is facing hard working condition.
30:05People thought they are kinds of heroes to stop spreading the nuclear elements from the reactor.
30:15But at the same time, we didn't care anyone in the zone, especially in the front line.
30:25That was so strange, I felt, because if they are heroes, we want and we needed to protect them.
30:47One hundred kilometres north of the nuclear crisis, aid was slowly arriving for survivors in areas cut off by the
30:55tsunami.
30:57We were getting deliveries of food from the self-defense forces from the self-defense forces from the city and
31:04so on, so it's basically nothing but kind of like the sort of sweet bread snack rolls that you can
31:11buy in convenience stores and also the onigiri rice balls, which they had like gathered from all over the country.
31:20They were past their sell-by date because it took a long time for them to make their way to
31:24us, but we were just grateful to have anything, and as long as it wasn't really rotten, then, you know,
31:29we could eat it to survive, and it wasn't much.
31:33We all lost a lot of weight then, but we were very grateful to just have that.
31:41For two days, flooding had prevented Ryoko Endo from trying to locate her children.
31:47But when the waters subsided, she went to find them.
31:51..
31:52Kayla because, across the line, she walked on again.
31:59Bailers cut out on them
32:01She left the wood canal when ideal.
32:04If she did fast.
32:05first of all, my area that is desperate for us.
32:10The hardest thing drove us into her town, so where they got sick and people got Julie wishes to help
32:12us,
32:12do a good moment since we reached, she was saying we wanted to come.
32:20I went to school, and I went to school, and I went to school, but there was noๅงฟ in there.
32:27I was wondering if there was a lot of people in my house who didn't see it, but I didn't
32:33know.
32:37I had a friend of mine, and I asked myself to talk to myself,
32:44I said he wasn't a child.
32:46He said he couldn't tell him.
32:50He said he couldn't tell him.
32:54He had no second at the home and said it,
32:58but he had no signs.
33:00He said, he said to him.
33:03And he said he could help him.
33:05The kids told him that he was teaching him.
33:06The ะผะตั‚ะพะด's story to go to school because he had no way.
33:12The way I was going to go to the street,
33:14and the wife said,
33:17she said,
33:19she said,
33:20she said,
33:23she knew the children's story.
33:39I was able to know that this was a bad dream.
33:43I was able to live in a long time and I couldn't believe it.
33:52I could not believe it was a bad dream.
33:53I couldn't believe it was a bad dream.
33:55I couldn't believe it was a bad dream.
33:55I couldn't believe it was a bad dream.
34:00I couldn't believe it was a bad dream.
34:07The devastation unleashed on 11 March 2011
34:23shocked the world.
34:28But tsunamis are a well-known risk in Japan.
34:32So why did this one trigger a nuclear disaster?
34:37One of the phrases that was used a great deal in the days after the tsunami hit is
34:47sotegai, which means beyond expectations.
34:51And in many, many ways, the tsunami was beyond expectations.
34:58That's the core explanation to some people or the excuse to other people for why the tsunami caused this crisis.
35:17One by one, Japan's nuclear plants were shut down until the cause could be established.
35:23Kazuto Suzuki consulted on an independent investigation.
35:30I was invited by the chief editor of one of the largest daily papers in Japan.
35:38And we set up the first investigation of the accident itself.
35:43But also we investigated the responses of the prime minister's office and the government.
35:53Three other investigations were launched.
35:57All agreed that a critical point of failure was the plant's level of protection against a large tsunami.
36:05The plant was originally designed to handle about a five-meter tsunami.
36:11But the actual tsunami goes up to the 15-meter high.
36:18And once the waves breached the plant, there was another weakness.
36:22When the tsunami hit the Fukushima Daiichi, the water flowed into the basement of the Fukushima Daiichi 3-8 reactors.
36:34And those reactors had emergency generators in the basement.
36:40The tsunami swamped the diesel generators, which were the main source of backup electrical power.
36:48Because water couldn't be cycled through the reactor to take away the heat,
36:52we had a situation where the reactor core, even though they were shut down,
36:57they started to get hotter and hotter.
36:59What that led to is the build-up of hydrogen.
37:02And what that means is you only need to have a spark for that hydrogen to explode.
37:06And that's exactly what happened.
37:11The first reactor of the Fukushima Daiichi was made by an American company.
37:16The higher risks for the American power plants were the tornado.
37:24So, you know, they naturally designed the generators to place in the basement where it is much more safer.
37:34But in Japan, you know, we don't have much tornado, but we have tsunami.
37:39So, putting the generators on the ground was not really the good idea.
37:50The scale of the disaster that followed shattered public confidence in nuclear power.
37:56There was shock in Japan, I think, that the system wasn't able to deal more effectively, faster, with the crisis
38:08at the plant.
38:09I think people had been reassured by the electricity utilities that their plants wouldn't get into this kind of problem
38:20as a result of an earthquake or a tsunami.
38:23When it did, I think people assumed that there would be an effective emergency plan and an effective backup to
38:33that emergency plan.
38:34And they were stunned to find that there wasn't really.
38:41The Fukushima clean-up is expected to last for decades, including dealing with vast quantities of contaminated water.
38:51So, there are lots of tanks everywhere in the Fukushima Daiichi plant.
38:58They are using every inches, every corner of the open spaces to store those tanks.
39:07But it comes to the, you know, to the limit.
39:12They quite quickly established a sort of filtration plant, which would take out the majority of all of the radioactive
39:21material that dissolved into the water.
39:23In terms of its radiological danger, it really doesn't present much hazard.
39:27So, the decision in the end was to start discharging into the sea through a pipeline that would go out
39:36off the coast.
39:37And to let the Pacific Ocean and dilution solve the problem.
39:44Meantime, a vast area around the plant has been scraped clean of surface radiation.
39:50But residents remain in fear of contamination.
39:54The thing that struck me most was that there was this lack of understanding of where the radioactivity had gone.
40:00So, one of the things that I did with my team at the University of Bristol is we got funding
40:05to develop a flying robot that could map radiation.
40:09And within weeks, we were flying in different parts of the exclusion zone in partnership with the Japan Atomic Energy
40:16Authority to understand the distribution of the fallout material.
40:23The forest litter and the bark and the moss on the bark are very good for holding the radioactive fallout
40:29particles.
40:29And so, by flying over the forest and we go several hundred meters into the forest or over the forest,
40:35we can measure the radioactivity without actually having to go in there.
40:40We would stay in a hotel near to, but not inside the exclusion zone.
40:46And on several occasions at the end of our stay, we would go to try and pay our hotel bill.
40:51And the manager of the hotel would say, your bill, everything's been paid already.
40:56And every time it was, you know, a local businessman wanted to express his gratitude for you coming to help
41:04our country.
41:05And, you know, this is a small measure of gratitude that we pay all of your costs.
41:14More than a decade later, the so-called difficult-to-return zone is shrinking.
41:20Mizuei Kano is considering moving back, but the decision stirs up traumatic memories.
41:50Mizuei Kano says,
42:04It was so strange feeling when I come back to home from Fukushima region, especially when I come back from
42:15the zone to my house, you know, in the zone everything is there.
42:22You know, housing, supermarket, and a convenience store, but no one there.
42:30The Japanese government, I think, has recorded something like 2,300 lives attributed to Fukushima.
42:36None of them to radiation, but a lot of them to induced mental ill health and suicide.
42:44And part of that is caused by, you know, this notion of am I contaminated, am I not?
42:49Am I going to die from cancer because of radiation exposure?
42:54All of the worries that are manifest because of the lack of understanding about radiological risk genuinely had a human
43:01toll.
43:04Am I going to die from the same time, I don't think I can live in the same way.
43:09Am I going to die from the same time?
43:14Am I going to die from the same time?
43:19Am I going to die from the same time?
43:32The tsunami that triggered the nuclear disaster claimed almost 20,000 lives, with more than 2,500 still missing.
43:51a few years later former lecturer richard halberstadt became a guide at a ruined school which serves
43:59as a memorial for the disaster i felt like i wanted to change even before the disaster
44:04um but i didn't really have the courage to leave the job um and ironically that terrible disaster
44:13gave me the courage to actually leave without knowing what i was going to do next because it
44:19it made me feel if i can live through this disaster i can i can just leave work and something
44:25will
44:25happen while working there richard met ryoko endo who lost her three children to the tsunami
45:01everything's changed in so many ways
45:04because on a more sort of philosophical level when you look at all the people who lost their lives
45:10then i'm much more appreciative of just life
45:16it made me think about my mortality speaking to so many people who had had their lives overturned
45:26and had had loved ones wake up in the morning and then be taken away by the sea
45:40so many people in the disaster zone dealt with this unspeakable tragedy with dignity and
45:53and grace that i found that inspiring as well so it was a anyway a privilege to be able to
46:02report on it
