Deconstructing the Nuclear Accident at the Fukushima-Daiichi Plant: What Went Wrong and What are the Prospects of Recovery?

The large-scale industrial accident at the Fukushima-Daiichi Nuclear Power Plant was the culmination of three inter-related factors: external natural hazard assessment and site preparation, the utility’s approach to risk management, and the fundamental reactor design.

The reactor accident was initiated by a magnitude 9 earthquake followed by an even more damaging tsunami. However, it was the inability to remove the decay heat in the reactor core that led to core meltdown and radioactive release.

A review of the timeline of the major Fukushima accident sequences: The plant first experienced a station blackout (i.e. loss of all offsite and onsite power) due to flooding of backup critical emergency cooling equipment. The lack of an ultimate heat sink led to the fuel overheating. Subsequently, the generation of hydrogen through steam oxidation of of the fuel cladding led to chemical explosions causing significant structural damage.

The focus of this talk (presentation slides below) is on the engineering aspects of the reactor accident and the prospects for local environmental recovery. Radionuclide measurements in space and time provide important evidence for the exact evolution of fuel damage leading to partial core melting in multiple units. A review of the spent nuclear fuel pools is given where isotopic water composition and visual inspection images provide important evidence for the condition of the spent nuclear fuel.

While it will be several months to a year before we will be in a position to learn most of the lessons from this tragdy, several conclusions about defensive design, mitigation actions, and emergency response have been drawn by international organizations.

While the public health impact appears to have been low, the economic and nearby environmental consequences are severe, There is no doubt that land restoration will take over a decade and perhaps much longer. A review is given of actions taken by the Japanese government for land recovery in areas such as decontaminating top soil and local farmland as well as highly radioactive water used during ‘feed and bleed’ cooling of the core.

The 8.9 earthquake and tsunami that struck Japan on March 11, 2011 set in motion one of the largest nuclear disasters in almost three decades. It also renewed the debate over the future of nuclear energy in the U.S. and abroad. With 104 nuclear power plants across the country, generating about 20 percent of America's energy, there is no doubt that we are currently dependent on nuclear energy, yet the debate over this highly contentious technology is far from resolved. At the World Affairs Council of Northern California, Thomas Isaacs discussed what this disaster means for the future of U.S. energy.

Powering America: Does Nuclear Have a Future?

CISAC's Tom Isaacs participated in a discussion on nuclear energy in America for the World Affairs Council Northern California. 

Event Description:

The 8.9 earthquake and tsunami that struck Japan on March 11, 2011 set in motion one of the largest nuclear disasters in almost three decades. It also renewed the debate over the future of nuclear energy in the US and abroad. With 104 nuclear power plants across the country, generating about 20 percent of America's energy, there is no doubt that we are currently dependent on nuclear energy, yet the debate over this highly contentious technology is far from resolved. The three panelists will discuss what this disaster means for the future of US energy. How will the disaster at the Fukushima Daiichi plant shape future energy policies and public opinion, and are there existing renewable technologies capable of fulfilling the world’s energy needs? Will nuclear energy be the fuel of the 21st century, or a relic of the past?

Kate Marvel and Michael May: What is the future of nuclear energy?

Paragraphs

“Anticipating the future is difficult in any situation, but assessing the prospects for nuclear power in the next fifty years presents especially complex challenges," write Katherine D. Marvel and Michael M. May in a new paper published by the American Academy of Arts & Sciences.

"The public perception of nuclear power has changed and continues to change. Once viewed as a miracle of modern technology, nuclear power came to be perceived by many as a potential catastrophe; now it is viewed as a potential, albeit potentially still dangerous, source of green power. Conventional wisdom in the 1960s held that nuclear power could dominate the electricity sectors of developed countries, while less than twenty years later, many predicted the complete demise of the U.S. nuclear industry following the Three Mile Island accident in 1979. Yet neither attitude fully forecast the situation today: a nuclear industry that is not dominant, but is far from dead. Indeed, the history of long-range planning for nuclear power serves as a caution for anyone wishing to make predictions about the state of the industry over the next half-century.

Nonetheless, it is critical to assess its role in the future energy mix: decisions taken now will impact the energy sector for many years. This assessment requires both a review of past planning strategies and a new approach that considers alternate scenarios hat may differ radically from business as usual. While a number of studies have explored the future of nuclear power under various circumstances, the purpose of this paper is to consider gamechanging events for nuclear energy.”

Anticipating the future is difficult in any situation, but assessing the prospects for nuclear power in the next fifty years presents especially complex challenges. The public perception of nuclear power has changed and continues to change.

The Battle of Chernobyl

(Russian/Ukraine/USA, 2006; dir. Thomas Johnson; 93 min.)

Wednesday, May 25, 2011

7:00 pm - 9:00 pm (*NEW TIME*)
Cubberly Auditorium

Free and open to the public 

On April 26, 1986, a reactor at the Chernobyl Nuclear Power Plant in the Ukrainian city of Pripyat exploded and began spewing radioactive smoke and gas. More than 40,000 residents in the immediate area were exposed to fallout a hundred times greater than that from the two atomic bombs dropped on Japan. Based on top-secret government documents that came to light only after the collapse of the Soviet Union in 1999, The Battle of Chernobyl reveals a systematic cover-up of the true scope of the disaster, including the possibility of a secondary explosion of the still-smoldering magma, whose radioactive clouds would have rendered Europe uninhabitable.
