A
worker was leaning over to retrieve a flashlight when he lost his
balance and fell into a reactor pool at the San Onofre nuclear power
plant last week but he did not receive a significant dose of radiation,
Southern California Edison officials said on Friday.
The
worker was wearing a life preserver when he fell into a pool more than
20 feet deep that holds water that circulates through the reactor core.
He received 5 millirems of radiation, Gil Alexander, a spokesman for plant operator Southern California Edison, told the North County Times.
Alarms
alerted station personnel to the leak at the power plant at about 6
p.m. Tuesday, according to the U.S. Nuclear Regulatory Commission.
Because
the building into which the gas leaked is not airtight, it is possible
that a small amount of radioactivity escaped into the environment,
officials said. But he said the levels would likely be immeasurable
against existing levels in the atmosphere.
The
leak occurred in the part of the facility, located off the I-5 just
south of San Clemente, which houses thousands of tubes carrying
radioactive water, officials said.
There are radiation detectors throughout the plant and none measured any amount of radioactivity, said Alexander.
The investigation into what caused Tuesday's leak continues. An evacuation was not required.
Officials were waiting for the reactor to cool before crews were sent in to analyze and fix the leak.
Once the problem is resolved, it will likely take several days for the reactor to be restarted, officials said.
This
was not the first time a leak scare has occurred at the San Onofre
plant. In November, a level 1 alert was issued at the plants, but the
appropriate alarms did not go off.
