Nuclear companies face reactor design problems, ethics questions
Federal regulators have expressed serious safety concerns about the design for 14 of the nation's 25 proposed new nuclear reactors, raising questions about the future of what the industry calls its "renaissance".
The Nuclear Regulatory Commission announced last
month that Westinghouse failed to demonstrate that the building designed to
shield its AP1000
reactor (pictured at right) from
outside threats such as tornadoes, hurricanes and earthquakes is adequate. In
addition, there are concerns about whether the shield building, which also
provides a radiation barrier, will be able to support the 8 million-pound
emergency cooling water tank that's supposed to sit on top.
"We've been talking to Westinghouse regularly about the shield building
since October 2008, and we've consistently laid out our questions to the
company," said Michael Johnson, director of the NRC's
Office of New Reactors. "This is a situation where fundamental engineering
standards will have to be met before we can begin determining whether the
shield building meets the agency's requirements."
Pennsylvania-based Westinghouse, which is owned
by the Toshiba Group of Japan, downplayed the NRC's concerns, releasing a statement that
said it "fully expected that the NRC would require additional analysis,
testing or actual design modifications to the shield building" and that it
had "already begun to address certain portions of the design." The
company says it remains "confident" it will answer the NRC's
concerns.
Whether
it does has important implications for the South's energy future, as all of the
planned AP1000 reactors -- designated by green squares on the NRC map at

units have been proposed at each of the following facilities:
* Tennessee Valley Authority's Bellefonte plant in Hollywood, Ala.;
* Plant Vogtle near Augusta, Ga., owned by Southern
Co. subsidiary Georgia Power.;
* Progress Energy's Levy County Nuclear Plant in Florida. and its Harris plant in
Wake County, N.C.;
* Florida Power & Light's Turkey Point plant in Miami-Dade County;
* South Carolina Electric & Gas Co.'s V.C. Summer plant northwest of Columbia, S.C.; and
* Duke Energy's Lee nuclear plant in Cherokee County, S.C.
But nuclear power watchdogs say the reactor's design problems should mean no
taxpayer money in the form of Department of Energy loan guarantees should go
toward its construction. Last month an alliance of 10 nuclear watchdog groups
including the Southern Alliance for Clean Energy and the NC Waste Awareness and
Reduction Network sent a letter [pdf]
to DOE officials calling on the agency to stop issuing conditional loan
guarantees to utilities using AP1000 technology. Among the new nuclear
projects with AP1000 reactors that the DOE is reportedly considering for loan
guarantees are the Vogtle site in Georgia and the Summer site in South Carolina.
"With billions of taxpayer dollars at stake in the proposed nuclear loan
guarantees, the Department of Energy owes it to the public to get on the same
page as the NRC about these serious AP1000 reactor design problems," said Sara
Barczak, a nuclear power specialist with SACE. "We believe that the DOE
should assure the public that utilities considering problematic nuclear reactor
designs, such as the AP1000, would not qualify for these loan guarantees."
A report released
earlier this year by the Union of Concerned Scientists found that the potential
risk exposure to the federal government and taxpayers from guaranteeing loans
to build new nuclear plants -- now estimated to cost upwards
of $6 billion each --
could range from $360 billion to $1.6 trillion. At the same time, a study put
out earlier this year by the University of Vermont Law School's Institute for
Energy and the Environment estimated the per-kilowatt cost of new nuclear
plants at two to more than three times the cost of efficiency and renewables.
But the nuclear power industry is pushing hard for more taxpayer assistance --
or what some of its critics are calling a "bailout." Last month, the
Nuclear Energy Institute, industry's lobby group, announced that
it wanted to build 45 new reactors by 2030 and was seeking $100 billion in
additional loan guarantees.
And the industry has key champions in Washington, as several moderate
Republicans including Sen. Lindsay Graham of South Carolina have said policies promoting nuclear
power would be necessary for them to vote in favor of climate legislation now
being considered in Congress.
Did the AP1000 get
improper insider help at the NRC?
Meanwhile, the other company behind the AP1000 -- the Shaw Group, which is
handling construction of the reactors -- is facing problems of its own related
to the project.
A major defense contractor and an important player in the post-Katrina reconstruction of the U.S. Gulf Coast, the
Louisiana-based Shaw Group is also the largest provider of commercial nuclear
power plant maintenance and modification services in the United States.
The company has long been known for working its insider connections. For
example, it was one of several firms that won contracts to rebuild the Gulf
Coast after Hurricane Katrina with the help of hired lobbyist Joe Allbaugh -- a campaign manager for former
President George W. Bush and that administration's
first FEMA director.
But now the Shaw Group faces questions about whether improper insider
connections at the NRC benefited its commercial nuclear power ambitions.
Back in 2007, the Project on Government Oversight reported that Nuclear Regulatory Commissioner
Jeffrey S. Merrifield "vigorously championed several major policy
initiatives that directly benefited his future employer": the Shaw Group,
who he went to work for 12 days after leaving the NRC.
The initiatives Merrifield promoted included a procedural change for certain
types of construction activities at nuclear plants that effectively eased
environmental restrictions. "Because Shaw is among the largest
construction companies in the nuclear industry, few companies stood to benefit
more from this initiative," POGO said at the time.
Then last month, the NRC Inspector General issued a report that confirmed Merrifield twice cast
votes during his time on the NRC regarding matters involving companies he had
contacted about jobs. The others were Westinghouse and General Electric. The
report said the firms could potentially have benefited financially from his
votes at the same time Merrifield was negotiating with them for jobs.
In one of the questionable votes, Merrifield voted to change the criteria for
emergency cooling systems, a change that would directly benefit Westinghouse,
of which the Shaw Group owned a 20% interest. He also approved a plan by the
Shaw Group to cooperate with China on building nuclear plants using AP1000
technology. China reportedly wants to have 100 AP1000 units operating by
2020.
Merrifield has denied that
his job search affected any decision he made while at the NRC. The IG has
referred the case to the Department of Justice.
