Three Fukushima Reactors Below Boiling Point

September 30, 2011

Plant Status

  • Tokyo Electric Power Co. announced this week that the three damaged reactors at Fukushima Daiichi now are below 100 Celsius at the bottom of the reactor vessels. Reactor 2 is the last reactor to drop below boiling point, after TEPCO in recent weeks began augmenting cooling by spraying water from above the fuel. Temperatures at reactors 1 and 3 have been below 100 Celsius since August. TEPCO said it would declare the reactors to be in a “cold shutdown” condition once the temperatures at the bottom of the vessels drop below 90 Celsius and other conditions are met to achieve stable cooling. The company expects to attain this goal by the end of the year.

Industry/Regulatory/Political Issues

  • The Japanese government today lifted evacuation advisories for five towns located between the 12-mile to 19-mile advisory ring around the Fukushima Daiichi facility. Residents in the advisory zone had been asked to evacuate or remain indoors. About half the population that chose to evacuate—about 28,500 residents—will be allowed to return to their homes. Evacuation orders within the 12-mile zone remain in place.
  • Japan’s upper house of parliament voted Friday to undertake a yearlong parliamentary investigation into the Fukushima accident. A 10-member panel of independent experts, to be appointed by lawmakers from both chambers, will be empowered to call witnesses and documents and will submit a draft report in about six months.

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap

An Ohio School Board Is Working to Save Nuclear Plants

By
Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Wednesday Update

By
From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin
