Lessons from the Fukushima Disaster
By Marin Katusa, Chief Energy Investment Strategist
December saw several new reports about the earthquake- and tsunami-induced Fukushima Daiichi nuclear disaster, so we thought it might be useful to assess what these new reports add to our understanding of the tragedy. And a tragedy it was: Lives were lost in the hydrogen-gas explosions that blew three of the reactors buildings to pieces; 160,000 people are still evacuated from the surrounding region; and the nuclear power industry took a well-deserved beating as each explosion and radiation reading reignited the public’s fears of uranium, radiation, and nuclear energy in general. Those fears bled 30% from the price of uranium and prompted several countries to abandon nuclear power. It seemed as though the budding renaissance of nuclear power had failed.
Now, almost ten months later, we know that the nuclear power industry remains alive and well (please see our mid-December Dispatch about the global race for uranium.) The uranium spot price has not recovered from the Fukushima fire sale, but in recent months it has stabilized at just over US$50 per lb. U3O8. Even accusations in these new reports of insufficient regulatory oversight and false claims that thousands of Americans died because of Fukushima radiation have failed to push the price down. Today, there are 12 more reactors in operation, under construction, planned, or proposed around the world than there were ten months ago.
All told, it seems that the nuclear-power industry and the price of uranium have found their post-Fukushima bottoms and are now set to climb upward. With the nuclear renaissance once again gaining momentum, what are we learning from Fukushima?
Key conclusion from the independent investigation: Be better prepared
In the week before Christmas, Japanese authorities finally achieved victory at Fukushima, declaring the half-destroyed plant stabilized. It will still take decades to dismantle the wreckage completely, and the 160,000 people who lived near the plant have still not been allowed to return to their homes. But the nine-and-a-half-month battle to cool radioactive fuel rods and seal off contaminated areas is finally over.
Less than a week later, an independent panel set up by the Japanese government to investigate the disaster released its interim report. It was not pretty. Led by Yotaro Hatamura, an engineering professor who specializes in the study of industrial failures, the panel concluded that TEPCO (the utility that owned and operated the plant) and government regulators from the Nuclear Industrial and Safety Agency (NISA): had failed to adequately anticipate a huge tsunami and its potential impacts; did not take steps to fortify the plant even after simulations years before the earthquake revealed its weaknesses; had no protocol in place in the case of a station blackout; and failed to communicate effectively with the public after the event, among other faults.
The Japanese should have known better. Japan lies on a highly active fault line, is regularly rocked by earthquakes, and has experienced tsunamis many times before. Even so, the engineers who designed Fukushima figured the biggest tsunami that could ever hit the plant would be 5.7 meters high. In this their imaginations failed them completely: Measurements from water stains on the walls after the waters receded indicate the March 11 tsunami towered more than 14 meters above normal sea level at its peak.
For this, responsibility lies with both TEPCO and NISA. According to Hatamura’s report, TEPCO failed to “incorporate measures against tsunamis exceeding the design minimum. This indicates the limit of voluntary safety measures.” Then, even after TEPCO ran simulations in 2008 and in early 2011 that highlighted Fukushima’s vulnerability to large tsunamis, NISA did not require TEPCO to take steps to address the weakness. More generally, no one had developed a protocol for what to do in the case of a full-station blackout – operators working with flashlights and dying cell phones had to make the plan up as they went along.
TEPCO and the government’s regulators share responsibility for setting themselves up for failure by not preparing for worst-case scenarios. However, after the tsunami swept the site, flooding the backup generators and plunging the entire facility into electrical blackout, TEPCO employees responded heroically while NISA regulators evacuated, even though protocol dictated they should have remained on site. In fact, Hatamura saved his strongest criticism for NISA: “Monitoring the plant’s status was the most important action at that time, so to evacuate was very questionable. [The panel] found no evidence that NISA officials provided necessary assistance or advice.”
Hatamura’s panel also hammered TEPCO and the government for failing to keep the public properly informed. “Information on urgent matters was delayed, press releases were withheld, and explanations were kept ambiguous.”
The 506-page report includes many more details, but what is most pertinent is the conclusion. Hatamura’s team argues that the Fukushima disaster shows the need for “a paradigm shift in the basic principles of disaster prevention” at nuclear power plants. “It’s inexcusable that a nuclear accident couldn’t be managed because a major event such as the tsunami exceeded expectations.”
And with that they hit the nail on the head. The Fukushima disaster does not mean that the world should turn away from nuclear power. Instead, government regulators around the world need to learn from what happened at Fukushima and strengthen their safety guidelines, because it was a preventable event.
Just because it is in a scientific journal doesn’t make it true
Here’s a catchy way to start a press release:
An estimated 14,000 excess deaths in the United States are linked to radioactive fallout from the disaster at the Fukushima nuclear reactors in Japan, according to a major new article in the December 2011 edition of the International Journal of Health Services.
The release goes on to describe how this peer-reviewed study shows that a “plume of toxic fallout arrived over American shores” just six days after the tsunami, causing as many as 18,000 deaths.
Catchy, perhaps, but totally bogus. Within 24 hours an article in Scientific American poked so many holes in the ‘study’ it could have been a sieve. Basically, the study’s authors started with an attention-grabbing conclusion – that babies are dying because of Fukushima radiation – and worked backward from that, torturing the data to fit their claims. Among the litany of errors were two key faults:
No journal should have ever published the study. Without a doubt, radiation from Fukushima is dangerous – the 160,000 people still unable to return to their homes can attest to that. There may well be some negative health effects in North America. But this ‘study’ provides zero evidence and serves only to add misinformation to a very important debate.
[What’s not open to debate is that, sooner or later, energy prices are destined to increase dramatically. That is creating a rare opportunity for life-changing gains.]
