US nuclear plant declares 'alert' after Sandy storm surge
The alert - the second lowest of four NRC action levels - came after water levels at the plant rose by more than 6.5 feet, potentially affecting the pumps that circulate water through the plant, an NRC spokesman said late on Monday.
Those pumps are not essential since the 43-year-old plant was shut for planned refueling since October 22. 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.
Exelon said in a statement that there was no danger to equipment and no threat to public health or safety.
