U.S. nuclear regulators say two Nebraska nuclear power plants have protected
critical equipment from the rising waters of the Missouri River even though
flooding has reached the grounds of one of them.
The Nuclear Regulatory Commission is confident those safeguards will prevent
a disaster at either plant even though the Missouri is expected to remain
flooded for several weeks, NRC spokesman Victor Dricks said Thursday.
The Fort Calhoun plant, about 20 miles north of Omaha, was shut down for
refueling in April. Parts of the grounds are already under two feet of water as
the swollen Missouri overflows its banks. But the Omaha Public Power District,
which owns the plant, has built flood walls around the reactor, transformers and
the plant’s electrical switchyard, the NRC said.
“They’ve surrounded all the vital equipment with berms,” Dricks said.
An 8-foot-tall, water-filled berm, 16 feet wide at its base, surrounds the
reactor containment structure and auxiliary buildings, the NRC says. The plant
has brought in an additional emergency diesel generator, water pumps, sandbags
and firefighting equipment as well, according to regulators.
Dricks said the NRC has sent additional inspectors to Fort Calhoun, which
declared an “unusual event” — the lowest level of alert — on June 6 due to
rising water. Six inspectors are now monitoring conditions there around the
clock, Dricks said.
The Cooper Nuclear Station, about 80 miles south of Omaha, remains operating
at full power. The plant issued an unusual event declaration on Sunday as water
levels rose, but the current level is two feet below the plant’s elevation,
The NRC will dispatch additional inspectors to the plant “if conditions
warrant,” Dricks said.
Heavy rainfall in Montana and North Dakota, combined with melting snow from
the Rocky Mountains, have sent the Missouri urging downstream this summer. The
river washed over and punched through levees in nearby northwestern Missouri
over the weekend, spurring authorities to urge about 250 nearby residents to
leave their homes.
The 6 to 12 inches of rainfall in the upper Missouri basin in the past few
weeks is nearly a normal year’s worth, and runoff from the mountain snowpack is
140% of normal, according to weather forecasters.
the Cooper Nuclear Station was commissioned on July 1st, 1974 according to http://en.wikipedia.org/wiki/Cooper_Nuclear_Station
July 1st, 1974
7 + 1 +1+9+7+4 = 29 = the Cooper Nuclear Station’s life lesson = what the Cooper Nuclear Station is here to learn = Competence.
July 1st, 1974
7 + 1 +2+0+1+0 = 11 = the Cooper Nuclear Station’s personal year (from July 1st, 2010 to July 1st, 2011) = Consequences.
11 year + 6 (June) = 17 = the Cooper Nuclear Station’s personal month for July 2011 = Going to take a miracle.
17 month + 26 (26th of the month on Sunday June 26th, 2011) = 43 = the Cooper Nuclear Station’s personal day = This is no fun.
