Tsunami

Last November, we told you about how the employees at the Onagawa nuclear energy facility in Japan played a critical role in sheltering local residents in the aftermath of the March 2011 earthquake and tsunami that struck the island nation.

While the Onagawa facility remains safely shut down, its employees are still at work preparing for the day when the plant may come back online. In this video report from NHK World, Onagawa’s employees are participating in a tsunami drill using new equipment acquired in the aftermath of the accident at Fukushima. In other news, a delegation from the International Atomic Energy Agency will be visiting Onagawa next week to begin a seismic inspection.

The following story originally appeared in NEI’s Nuclear Energy Overview.

The tsunami that brought about the nuclear accident at Japan’s Fukushima Daiichi facility was not adequately accounted for in the facility’s design basis, said a co-author of a report for the American Nuclear Society.

Michael Corradini, co-chair of the ANS’ special committee on Fukushima, told the National Academy of Sciences this week that the March 11, 2011, tsunami that disabled the nuclear power plant was not entirely unforeseen, because larger tsunamis have occurred in that region of Japan in recorded history.

The following story originally appeared in NEI’s Nuclear Energy Overview.

Inadequate forecasting of the maximum possible tsunami height led to flaws in flooding protection design for the Fukushima Daiichi plant, resulting in last year’s reactor accident in Japan when the tsunami that struck the plant exceeded the plant’s design basis.

A new analysis by the Electric Power Research Institute said the facility also had limited protection and mitigation capabilities for coping with events that exceed what is accounted for in its design, causing the reactors to lose cooling and backup power and ultimately leading to fuel damage and the release of radiation to the environment.

One year ago, a powerful earthquake and tsunami devastated the northeast coast of Japan, leaving more than 19,000 people dead or missing and thousands more homeless. We continue to remember the Japanese people for all that they lost in this horrible act of nature and continue to support their recovery. The entire world marveled at the resilience of the Japanese people in the face of this calamity.

Those of us in the nuclear energy industry were particularly struck by the tireless efforts of the workers who, in the face of destruction of the storm and uncertainty for their families, labored to stabilize the damaged reactors at the Fukushima Daiichi nuclear plant.

Japanese officials continue to monitor radiation levels in the air, water, soil, crops and livestock in an ongoing effort to protect public health.

Ongoing environmental monitoring helps Japanese officials to protect public health.

When a mega-quake followed by a massive tsunami struck Japan last March, the country’s defenses were overwhelmed by the scale of the natural disaster. While the earthquake and tsunami caused catastrophic destruction and significant loss of life, radiation released from the Fukushima Daiichi reactors has not caused a single death. In fact, the radiological consequences of the accident to date are negligible, due in large part to emergency response plans that were in place before the incident.

“The reporting of Fukushima was guided by the Cold War reflex that matched radiation with fear and mortal danger,” writes Wade Allison, emeritus professor of physics at Oxford University in the UK newspaper, The Telegraph. “Reactors have been destroyed, but the radiation at Fukushima has caused no loss of life and is unlikely to do so, even in the next 50 years.”
