An "alert" has been issued at the New Jersey Oyster Creek
nuclear power plant due to a record storm surge, the Nuclear Regulatory
Commission said.

A further rise in water levels could force operators to use emergency
water supplies from a fire hose to cool spent uranium fuel rods. The alert –
the second lowest of four NRC action levels – came after water levels at the
plant rose by more than 6.5 feet (2 metres), potentially affecting the pumps
that circulate water through the plant, an NRC spokesman said.
Those pumps are not essential since the plant is shut for planned
refuelling at the moment. However a further rise to 7 feet could submerge the
service water pump motor that is used to cool the water in the spent fuel pool.
The spokesman said the company could use water from a fire hose to cool
the pool if necessary. The used uranium rods in the pool could cause the water
to boil within 25 hours without additional coolant; in an extreme scenario the
rods could overheat, risking the eventual release of radiation. The NRC said in
a statement that it expected water levels would begin to abate within the next
several hours.
Sandy made landfall earlier in the evening as the most powerful Atlantic
storm to hit the United States, bringing an over 13-foot storm surge. There
have been about a dozen instances of alert-level nuclear incidents in the past
four years, according to NRC press releases. An alert-level incident means
there is a "potential substantial degradation in the level of safety"
at a reactor. The concerns over the status of the spent fuel pool at Oyster
Creek were reminiscent of the fears that followed the Fukushima disaster in
Japan last year, when helicopters and fire hoses were enlisted to ensure the
pools remained filled with fresh, cool water. The nuclear industry has said
that the spent fuel rods at Fukushima were never exposed to the air.
