Tenn. Valley Authority Responds to NRC Report on Japan Nuke Disaster

Tenn. Valley Authority Responds to NRC Report on Japan Nuke Disaster | Nuclear News | What The Physics? | Scoop.it
A Tennessee Valley Authority spokesman said the utility started making safety changes before a Nuclear Regulatory Commission panel released its report on Japan’s nuclear disaster.

The NRC panel has recommended that all nuclear plants re-evaluate their earthquake and flood risk, add equipment to deal with simultaneous damage to multiple reactors and make sure electrical power and instruments are in place to monitor and cool spent fuel pools after a disaster.

TVA spokesman Ray Golden said in a statement that so far since the March 11 earthquake and tsunami that cut off all electrical power to the plant in Japan, TVA has purchased additional satellite phones, gasoline-powered generators and diesel-powered fire pumps.

The NRC task force said there is no imminent risk from nuclear power plants in the United States

NRC chairman proposes timetable for nuclear industry reforms

NRC chairman proposes timetable for nuclear industry reforms | Nuclear News | What The Physics? | Scoop.it
Washington (CNN) -- The chairman of the Nuclear Regulatory Commission said Monday the NRC should move quickly on post-Fukushima reforms, saying the commission should draw up proposed changes within 90 days, and the industry should implement them within five years.
NRC Chairman Gregory Jaczko reiterated his belief nuclear power plants in the U.S. are safe and that a Fukushima-type event is unlikely -- a reference to the the triple meltdown at Japan's Fukushima Daiichi power plant after an earthquake and tsunami in March.

Last week, an NRC task force completed its 90-day "quick look" at Fukushima, and made 12 recommendations, some of them sweeping in nature. Perhaps most significant, it calls on the NRC to replace a "patchwork" of regulations developed over the years with "a logical, systematic, and coherent" regulatory framework.

It also recommends the commission require power plants to upgrade protections to nuclear reactors and spent-fuel pools to further protect them from earthquakes, floods and fires.
The task force also said the NRC should require nuclear power plants to be better prepared to handle power blackouts and events that affect more than one reactor.

"In light of the task force's work, I see no reason why the commission cannot provide clear direction on each of their recommendations in less than 90 days," Jaczko said. "That is the time the commission gave the task force to do its job, and I believe that is more than enough time for the commission to outline a clear path forward."

Both the NRC and the nuclear industry, he said, should "commit to complete and implement the process of learning and applying the lessons of the Fukushima accident within five years -- by 2016.".

Japan bank lobby:Tepco would face insolvency without bailout scheme

Japan bank lobby:Tepco would face insolvency without bailout scheme | Nuclear News | What The Physics? | Scoop.it
(Reuters) - The head of Japan's banking lobby said on Thursday that Tokyo Electric could become insolvent if parliament fails to pass a bailout bill by the end of September, when the operator of the crippled Fukushima nuclear plant closes books for the fiscal first half.

Katsunori Nagayasu, chairman of the Japanese Bankers Association, told a regular news conference time is running out as the government panel on nuclear damages compensation is set to release guidelines around late July.

"It will be known how much the compensation will be in rough figures, but if there is no (government) scheme for that then, Tokyo Electric could immediately become insolvent," he said.
"And it will trigger a series of risks for the power industry and the markets and put a damper on Japan's reconstruction efforts," he said.

Japan's parliament has started deliberations on a bill to set up a fund to help the operator of crippled nuclear reactors in Fukushima pay for damages, which could total billions of dollars.
Japanese banks, including Nagayasu's Mitsubishi UFJ Financial Group , provided a total 2 trillion yen in March in emergency loans to Tokyo Electric.

The creditors has been pushing for strong government commitment to keeping Tokyo Electric solvent and listed on the stock exchange, fearing a massive shock to the equity and bond markets in case of its default.

Nagayasu also said the direct impact from U.S. and European debt problems is relatively limited on the Japanese economy. But the European sovereign issue has various indirect ramifications, including a higher yen.

"A continued rise in yen would deal a great blow to the Japanese economy," he said.

Why was Japan so unprepared for the Fukushima nuclear accident?

Why was Japan so unprepared for the Fukushima nuclear accident? | Nuclear News | What The Physics? | Scoop.it
Many models have been created that have shown the correlation between the probability of an accident, with the state of preparedness in that area. In other words, the more likely an event, the more informed and prepared those in the effected area will be.

In this investigation I will use the probability of the occurrence of two events according to the AND logical gate, to demonstrate one way that the earthquake and tsunami on March 11th was likely underestimated in Japan. The two events may have been considered ‘independent events’ which would have caused their estimated probability of occurrence to be substantially less than a ‘common mode failure’ event.

reactor safety pros's comment, July 18, 2011 9:22 PM
You are absolutely correct. The probabalistic risk assessment models are wrong. Further, Japan did not consider the full license duration of 40 years in their analyses for initial license application. They only considered 30 years. That additional 10 years made a huge difference in their acceptable model.

And they still try to extend the licensing. Thanks for sharing rsp!
