Nuclear Event in USA on Sunday, 28 July, 2013 at 04:12 (04:12 AM) UTC.

Description
The in-house fire brigade quickly contained and extinguished a small fire at the nuclear power plant just outside Fulton late Friday night, according to officials. At 11:49 p.m. Friday, Ameren Missouri Callaway Energy Center declared an "Unusual Event" due to a small fire in the turbine building, a press release from Ameren Missouri electric company stated. "At no time did the situation threaten the public or nearby communities. No one was injured," the press release stated. Barry Cox, senior director of nuclear operations for the Callaway Energy Center, told the Fulton Sun there is a fire brigade on duty 24 hours per day, seven days per week and was able to put out the fire. "No off-site assistance was required," Cox said. Though the turbine building is located in a non-nuclear part of the plant near Fulton, the facility was shut down as part of the multiple safety layers. "Our first priority was stabilizing the nuclear plant ... everything operated per design," Cox said. He said the fire was minimal - just inside a small room in the turbine building and outside near auxiliary transformers.Ameren Missouri and the U.S. Nuclear Regulatory Commission (NRC) have started an investigation. The term "Unusual Event" was established by the NRC to describe a relatively minor occurrence at a nuclear power plant that could reduce the overall level of safety. During such an event, no public action is advised or necessary. It is the least significant of four emergency classifications established by the NRC. The other categories, in order of severity, are "Alert," "Site Area Emergency" and "General Emergency," according to the press release. There was no release of radioactivity to the environment above normal operating limits, the press release stated, and all appropriate federal, state and local agencies have been notified. An assessment is underway to determine when Callaway can return to service. Cox said crews were on site Saturday afternoon to survey the damage and determine a cause. He did not know when a cause would be determined nor when the plant would return to service and could not estimate when that knowledge would be available. The Callaway Energy Center generates about 20 percent of the electricity supplied to Ameren Missouri’s 1.2 million customers, according to the press release. While out of service, the energy it produces will be replaced by other Ameren Missouri energy centers.

Tepco Under Increasing Fire Over Nuclear Accident Site

Wall Street Journal


Panel Appointed by Firm Criticize Slow Release of Information


    By
  • MARI IWATA
TOKYO—As problems mount at the crippled Fukushima Daiichi power plant, more experts and overseers are accusing the operator Tokyo Electric Power Co. 9501.TO -9.84% of incompetence in how it is dealing with one of the world's worst nuclear accidents.
An advisory panel of outside experts—appointed by Tepco itself—blasted the utility on Friday for its slow release of information about a recent leak of radioactive water.
The panel, which is tasked with making recommendations to improve Tepco's performance after the missteps surrounding the 2011 accident, said that the company needed to improve its risk management, communication and water-management planning.
"I'd like to say myself how disappointed and distressed I was when I arrived in Japan," said Barbara Judge, a former chair of the British Atomic Energy Authority and deputy chair of the panel. "To find that communications with respect to the leak problem have been so difficult and so late was very devastating," she said.
Underscoring the concerns, just a day after the panel's meeting, the utility said that it had found new dangerous levels of radiation in a trench near one of the heavily damaged reactors.
Earlier in the week, Japan's nuclear regulator had also expressed skepticism about Tepco's ability to keep the situation at the damaged plant under control.
"It is simply too big for one company to handle," said Shunichi Tanaka, Nuclear Regulation Authority chairman, at a news conference Wednesday. "Placing all the burden (of controlling the site) on them won't solve the problem."
Mr. Tanaka suggested that the government may have to eventually step in with money and other resources to help out.
"As the organization in charge, we can only say we will tackle the challenges in a responsible manner," a Tepco spokesman said in reply to Mr. Tanaka's comments.
Tepco's decommissioning effort has already been aided by ¥99.7 billion ($1 billion) in government financing for research and development of new technologies, he said, and Tepco is planning to work with nuclear-equipment makers such as Hitachi Ltd. and Toshiba Corp.in dismantling the plant.

International nuclear experts tell TEPCO ‘You don’t know what you’re doing’


International nuclear experts tell TEPCO ‘You don’t know what you’re doing’
Two international nuclear experts who were invited to a nuclear reform monitoring panel took to task the organizer, Tokyo Electric Power Co (TEPCO) for their handling of the toxic water leaks at their crippled Fukushima Daiichi nuclear plant. The operator has been facing problem after problem ever since the 2011 earthquake and tsunami resulted in a nuclear meltdown in Fukushima, the worst nuclear disaster in recent history.
Dale Klein, former head of the US Nuclear Regulatory Commission (NRC) bluntly told the panel, composed of two foreign experts and four Japanese members including TEPCO’s chief executive, that their actions indicate they “don’t know what you are doing,” and that they do not have a conservative decision-making process. “It also appears that you are not keeping the people of Japan informed…and that you are not doing all you can to protect the environment and the people,” Klein blasted at TEPCO. He added that everyone is frustrated with the recent developments, and that because of this all the progress they’ve made on the clean-up at the plant will go unnoticed.

Radiation in the water at Fukushima as high as in 2011


15 hours ago by in National

The radiation in the water leaked from the premises of the Fukushima nuclear power plant is as high as it was during the 2011 disaster caused by the earthquake and tsunami that hit Japan.
Tokyo Electric Power Co. (TEPCO) said Saturday it has detected 2.35 billion becquerels of cesium per liter from water in an underground passage at the crippled Fukushima Daiichi nuclear power plant that is leaking into the sea. This is roughly the same level as the level of radiation measured in April 2011, shortly after the nuclear disaster the preceding month.
The water sample taken Friday from a trench contained 750 million becquerels of cesium-134 and 1.6 billion becquerels of cesium-137 per liter, while 750 million becquerels of other radioactive substances were detected, according to TEPCO, quoted by Kyodo.
