American NRC disclosed on the 26th, a nuclear power station of Ohio state detected last week that went beyond normal lateral high radiation, impel regulator of this nuclear energy to start to especially investigate.
NRC issues a statement to say, finds on the 22nd of this month the radiation level in the factory rises in changing the course of shutting down of fuel in Northeast Perry nuclear power station of Ohio state, all staff evacuate immediately.
The owner of nuclear power station ” The first energy ” The company says, when the radiation level rises, 4 staff are moving a detecting instrument, the instrument measure pile during start specially nuclear reaction state when low power run and shut down.
” the first energy ” Spokesmans of company Todd and Schneider say, these staff are contracted workers, worked in the basement under pile at that time, have not ” adopted the rational method to carry this instrument ” .
Schneider says, the highest radiation yield that the staff may suffer is 98 fine long hair Lam in the factory when the accident happened, accept two to X light-struck three times in other words. 100 fine long hair Lam is equivalent to a fine long hair sievert Sv.
NRC limits acceptable maximum radiation yield of every year of the human body as 5000 fine long hair Lam.
Schneider says, though the radiation level ” exceeds NRC to limit the standard ” ,But the staff have not suffered radiation, the nuclear fuel changes the work and goes on on schedule. “This incident should not happen, but not gone beyond the bottom margin, has not influenced these contracted workers or public security or healthy. ”
NRC approves ” the environmental security of factory, this incident has no effect on staff or the public of hydropower station ” .
Regulator of this nuclear energy declares, investigate that begins on the 25th. But declare not to mention the concrete number value of the radiation level when the accident happened, does not have and introduce this kind to especially investigate the frequency started.
Perry nuclear power station lies in the most populous city Cleveland Northeastern direction in Ohio state, stood 56 kilometers apart, put into operation in 1987.
Associated Press’ report, the incident happens many times in this nuclear power station. In 2005, the pile nuclear core recirculating cooling system water pump broke down, forced the nuclear power station to close temporarily. NRC checked production safety every 3 months that year. Last March, a water pump of lubricating system of nuclear power station caught fire, the intensity of a fire was not big, but lasted several hours.
