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,
Dricks said.

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.

A water-filled berm protecting a nuclear power plant in Nebraska from rising
floodwaters collapsed Sunday, according to a spokesman, who said the plant
remains secure.

Some sort of machinery came in contact with the berm, puncturing it and
causing the berm to deflate, said Mike Jones, a spokesman for the Omaha Public
Power District (OPPD), which owns the Fort Calhoun plant.

The plant, located about 20 miles north of Omaha, has been shut since April
for refueling.

“The plant is still protected. This was an additional, a secondary, level of
protection that we had put up,” Jones said. “The plant remains protected to the
level it would have been if the aqua berm had not been added.”

Parts of the grounds are already under water as the swollen Missouri River
overflows its banks, including areas around some auxiliary buildings, Jones
said.

In addition to the berm, authorities have put in place floodgates and other
barriers to help protect the facility, like sandbags.

The 8-foot-tall, water-filled berm, 16 feet wide at its base, surrounded the
reactor containment structure and auxiliary buildings, according to the Nuclear
Regulatory Commission.

“We built the plant up high enough based on history, based on the flooding in
the past. If the flood would rise for some reason above that level we have taken
precautions, again, per our procedures to sandbag the important equipment for
the reactors,” said Dave Van Der Kamp, with the NRC.

He said the chances of floodwater getting into the building where the core is
kept are almost zero.

The plant is designed to withstand waters up to 1,014 feet above mean sea
level, according to the OPPD. The river currently stands at 1,006.3 feet and is
not expected to exceed 1,008 feet, the Power District said.

Heavy rainfall in Montana and North Dakota, combined with melting snow from
the Rocky Mountains, have sent the Missouri surging downstream this summer. The
river washed over and punched through levees in nearby northwestern Missouri,
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 forecasters.

It was catastrophic flooding from Japan’s March 11 tsunami that knocked out
cooling systems at the Fukushima Daiichi nuclear power plant, resulting in three
reactors melting down and producing the worst nuclear disaster since Chernobyl.
This year’s Midwestern flooding has also led to a spate of rumors about the Fort
Calhoun plant that OPPD and the NRC have been trying to knock down.

The utility has set up a “flood rumor control” page to
reassure the public that there has been no release of radioactivity from the
plant. An electrical fire June 7 did knock out cooling to its spent fuel storage
pool for about 90 minutes, but the coolant water did not reach a boiling point
before backup pumps went into service, it has said.
