The Canadian to be reviewed nuclear power safety


The Canada has five nuclear power plants in different States of operation.

The Canadian Nuclear Safety Commission has established a working group to assess the impact of operational, technical and regulatory of the nuclear disaster at the Japan for the Canadian plants.

Fukushima Daiichi nuclear complex was severely damaged by the March 11 earthquake and the tsunami that hit the northeastern coast of the Japan and continues to release radiation into the environment as officers work desperately to get the reactors under control.

The Canadian commission has decided to implement the Working Group at its meeting of March 30.

"The members of the Working Group will examine the responses of the licensees at the request of CNSC information under subsection 12 (2) the General nuclear safety and regulation of review to review the respective cases of the safety of their nuclear installations."", underlying in-depth defence against externesscénarios of serious accidents and guidelines and emergency procedures," said a press release of the CNSC.

The Canada has seven nuclear power plants located at five locations in Ontario, Quebec and New Brunswick.

Employment of the Working Group will be recommending short and long term measures to address Canadian nuclear Central significant deficiencies and determine if design changes are necessary.

The Working Group recommends that, if appropriate, potential changes in regulatory requirements, for inspection and programs policies for CANDU reactors and for potential new nuclear power plants, according to the release of the commission.

Members will also determine priorities for the implementation of corrective actions based on lessons learned and the need, if any, for further examination. The Working Group will present its findings to the commission at a public forum, even if the date has not yet been decided.

The Working Group will be chaired by Greg Rzentkowski, the Director-General of regulation of nuclear power, and members will consist of senior experts in the design of the reactor, security assessment and the emergency preparedness and response.

The most recent accident at a Canadian nuclear power plant was in mid-March when 73 000 litres of water demineralized leak in Lake Ontario of the Pickering a nuclear power plant.

Ontario Power Generation, which operates the plant, located 35 kilometres east of Toronto, told the CNSC that seal of pump failure was the cause.

Ontario Power Generation, said that the risk was minimal, but that these leaks are not supposed to happen.

Japan sets radiation safety limits for fish

The Japanese Government has imposed a legal limit for radioactive iodine in fish. Workers at the nuclear power plant in Fukushima pumps have radioactive water in the ocean. Movement has concerns about marine life in the country, according to where a major source of protein is seafood.

Japan on Tuesday imposed a permitted for radioactive iodine in fish, as the operator of the Fukushima nuclear plants toxic water for a second day in the Pacific Ocean pumped.

The Government also said it would look, cover expanding their tests, to a greater range of radioactive iodine into a small fish caught off Ibaraki Prefecture elevated levels, discovered south of the plant.

The move came as shares in Tokyo Electric Power Co. to a new low of 362 Yen stürzte-- their lowest ever level-in the midst of concerns that the operator of Japan's crippled nuclear power plant huge compensation bills will be exposed to.

The embattled company has lost more than 80 percent of its value since the March 11 Quake and tsunami reactor knocked cooling systems explosions and releasing radiation on the nuclear power plant in Fukushima, triggering.

On Monday, low-level radioactive water into the sea to much-needed safe storage for water began as toxic free crucial being repairs curb its operators.

The company has said it concerns the cause of marine life in the island nation, where seafood is an important source of protein to dump 11,500 tons or more than four Olympic pools worth, the radioactive liquid.

Some radioactive runoff increase the iodine-131 to more than 4,000 times the permitted is leaked in a measure already in the Pacific Ocean.

On Tuesday chief Government spokesman Yukio Edano announced 2,000 becquerels per kilogram for radioactive iodine in seafood legal maximum, the first time, which it has imposed such a restriction on fish.

"Because it has no set limit for radioactive iodine in fish, the Government decided, temporarily take the same limit for vegetables," he said at a press conference.

The move came more than twice as high for radioactive iodine that concentration in a variety of small fish, known surprised was detected as Konago or sand Lance, Ibaraki Prefecture, South of the plant.

Fishing of the species was local, held at media reports that, but no larger ban was issued.

Radioactive iodine about legal limits in the dairy products, vegetables, mushrooms, triggering sending detected prohibitions, but officials had said, seafood was less at risk, because dilute sea currents and tides of the dangerous isotopes.

Fishermen in the area expressed outrage over the decision to dump radioactive water in the ocean, saying they had not been consulted.

"We have been reported..." You can believe? ", said Yoshihiro Niizuma Fukushima fisheries cooperative." "Was we heard, radioactive substances into the sea leaking." "Now they dumping are contaminated water on purpose."

Seoul questioned the decision, pump radioactive water in the ocean, say that made close to the two neighbors of Japan's action "a pressing issue" for South Korea.

Fishing is prohibited within 20 kilometres (12 miles) of the affected plant, matching the radius of the evacuation zone in the country, where tens of thousands of residents from have been moved.

The Yomiuri Shimbun on the Tuesday reported TEPCO has decided to offer preliminary damage payments inhabitants and farmers in the vicinity of the plant before the official damage amounts later be estimated.

But the dumping of radioactive water into the sea has also post concerns the result of the fishing industry, and some analysts estimate that TEPCO was claims for damages of more than 10 trillion yen ($ 120 billion).

The company said last week it had secured a 2 trillion yen ($ 24 billion) in funding but warned that this would be not enough.

The larger economic impact of Japan's triple Calamity--the massive March 11 earthquake, huge tsunami and the nuclear crisis-probably said a survey of economists drive the country into recession in the coming months.

The disaster which has left more than 12,000 dead and missing of 15,000, has taken also exports, business confidence and consumer spending, the Nikkei said daily in the overview of the 11 large private economic institutions.

On Tuesday, would Tokyo two police, arrested for the sale of one drug use, which protect them alleged people leaking from the radiation from the plant.

The couple, a 50-year old health food retailer and his assistant, 29-year-old the unlicensed sale of medicine accused, a police spokesman said.
