Two nuclear power reactors which were shut down as Hurricane Irene swept up the east coast of the USA have now been restarted. Exelon's single-unit Oyster Creek plant in New Jersey was taken offline on 27 August as a precaution against the approaching hurricane-force winds. The utility, having found that the reactor had not sustained any damage, announced that the 636 MWe boiling water reactor had restarted operation on 30 August. Constellation reported on 31 August that it had restarted unit 1 at its Calvert Cliffs plant in Maryland. The 825 MWe pressurized water reactor shut down automatically after aluminium cladding dislodged from a nearby building hit a transformer, while the plant's second unit continued to operate safely.

8/31/2011 FACTBOX-US nuclear facilities back in restart after Irene
Source: Reuters
Date: Wed Aug 31, 2011 3:27pm GMT
Aug 31 (Reuters) - The following lists nuclear power plants in the path of Hurricane Irene and
their status as of early Wednesday.
Some plants remained fully operational through the storm, while a few were shut or reduced power in advance of expected major storm surge.
In Maryland, Constellation Energy Nuclear Group's Calvert Cliffs 1 facility remained shut offline after a transformer was hit by a section of aluminum siding during the storm.
The North Anna nuclear plant in Virginia remains shut following last week's earthquake in the region. The plant cannot be restarted until the operator can show no functional damage occurred to equipment needed for safe operation. [ID:nN1E77S184]

Date: 8/28/2011
Two nuclear power plants have shutdown as Hurricane Irene continues to track up the US east coast. Oyster Creek, operated by Exelon in New Jersey, was powered down at around 17:00 EST, Saturday, as high winds approached. CENG's Calvert Cliff unit 1 reactor, based in Maryland, shut down automatically after aluminium debris hit a transformer.

8/27/2011Factbox: Status of nuclear plants in Hurricane Irene's path
Source: Reuters via CNBC
Date: Saturday, 27 Aug 2011 9:37 PM ET
Nuclear power plants along the East Coast prepared to face the impact of Hurricane Irene on Saturday as the storm made landfall in North Carolina and barreled up the coast.
Exelon Corp took its Oyster Creek nuclear power plant in New Jersey offline at 5 p.m. EDT on Saturday.
The U.S. Nuclear Regulatory Commission said it sent additional staff to monitor conditions and storm preparation at the 14 nuclear units from Maryland to New Hampshire in Irene's path as well as a nuclear fuel production plant in North Carolina.
Entergy Corp, which operates the Indian Point nuclear plant in Buchanan, New York, said operations were not affected by the hurricane and the plant remained open on Saturday evening.
Dominion Resources Inc is reducing power at its two-unit 2,111-megawatt Millstone plant in Connecticut ahead of the storm, a company spokesman said on Saturday.
Progress Energy's Brunswick nuclear plant, perched on the North Carolina coast, cut to 65 to 75 percent power late on Friday and does not expect to return to full power until after the storm has fully passed, a spokesman said on Saturday.
Dominion shut down its North Anna nuclear power station because of an earthquake on Tuesday. The two-unit, 1,950-megawatt North Anna plant will remain shut through the storm.
The company's two-unit, 1,598-MW Surry plant in Virginia was designed to withstand winds of 360 mph and is expected to remain at full power throughout the storm, a spokesman said on Saturday.

8/26/2011 Nuclear plants in Hurricane Irene's path

Nuclear reactors sit on eight coastal sites along the Eastern seaboard in the projected path of Hurricane Irene. They are built to withstand winds much stronger than those expected from Irene. They are also equipped with backup generators protected from flooding to provide power to keep the reactor cool if outside power is lost. Still, some will likely be shut down as a precaution in advance of Irene's winds and heavy rains.
