U.S. nuclear power plants prepare for Hurricane Florence

    Sept 11 (Reuters) - Several nuclear power reactors in North
and South Carolina and Virginia on Tuesday started to prepare
for Hurricane Florence, which is expected to hit the coast as a
major hurricane on Friday.
    The storm threatened to make landfall with massive waves and
winds of up to 130 mile per hour (209 km per hour), making it a
Category 3 or 4 storm on a five-step scale, the National
Hurricane Center in Miami warned.
    There are 16 nuclear reactors in North Carolina, South
Carolina and Virginia, the states expected to suffer the most
damage from Florence. 
    Florence will most likely affect Duke Energy Corp's
1,870-megawatt (MW) Brunswick and 932-MW Harris nuclear plants
in North Carolina and, if it turns north, Dominion Energy Inc's
 1,676-MW Surry plant in Virginia, Roger Hannah, spokesman
for the U.S. Nuclear Regulatory Commission's (NRC) Region 2
office in Atlanta said on Tuesday.
    One megawatt can power about 1,000 U.S. homes.
    Duke said it could take days to several weeks to restore
power to all customers after a storm like Florence depending on
the extent of damage and post-storm conditions.
    "We anticipate Hurricane Florence to be a historic storm
that will impact all customers," said Grace Rountree, a
spokeswoman for the company. Duke serves 4 million customers in
the Carolinas.
    To prepare for the storm, nuclear operators check on backup
diesel generators to make sure they have enough fuel, conduct
site walk downs and secure any loose equipment that could become
a projectile in the wind, said Hannah at the NRC. 
    "Most of the plants have gone through or are going through
their pre-storm preparations now," Hannah said.
    About 12 hours before the hurricane arrives, the reactors at
the nuclear plants will be shut down, Hannah said.
