As radioactive waste mounts and Yucca Mountain stalls, pressure grows
for an interim storage site

By Jeff Johnson, C&EN Washington

Over the past few weeks, energy companies and Congress have advanced
plans to build a centralized interim storage facility for spent fuel
from commercial nuclear power plants. Such projects are gaining new
urgency as radioactive waste grows--because of industry and government
support for life extensions for existing reactors and plans for new
ones--while work on a permanent repository remains stuck.

On May 24, a facility to be built in Utah by a private consortium of
energy companies inched closer to reality with approval by an
independent panel of the Nuclear Regulatory Commission. The facility
would be located on an Indian reservation and is being fought by the
state. A final decision must go to NRC, which is expected to back the
facility. In the end, a court is likely to decide its fate.

So far, the company, Private Fuel Storage LLC, has won every battle in
its eight-year quest for construction. Sue Martin, a PFS spokeswoman,
says the company hopes to have the site operating by 2007 or 2008. The
facility will be mostly a controlled-access slab of concrete, designed
to be operated for 40 years and house 40,000 metric tons of waste,
more than half the capacity of the long-delayed Yucca Mountain,
Nevada, federal underground nuclear waste repository.

Also on May 24, the House passed legislation that would fund a
government-run interim spent-fuel storage facility as part of an
appropriations bill for the Department of Energy for next year.

In legislative language accompanying the bill, Rep. David L. Hobson
(R-Ohio), chair of the House Appropriations Subcommittee on Energy &
Water Development and the bill's author, laid out his frustrations
with delays at Yucca Mountain and called for DOE to investigate the
legality of a federal interim storage facility. Hobson and other House
members want DOE to begin receiving waste at a federal site in 2006.
The House members also included provisions to encourage reprocessing
of spent fuel to reduce the volume of high-level radioactive waste
eventually headed for permanent disposal.

DOE is taking a hard look at Hobson's proposal, Deputy Secretary of
Energy Clay Sell says. "We remain committed to Yucca Mountain. We know
we have challenges there, but we are still confident that we can get a
license from NRC."

But, he adds, even if Yucca Mountain opened in 2010--the putative
goal--by that time, enough commercial spent fuel would have been
generated at existing reactor sites to exceed the repository's 70,000-
metric-ton capacity. "Other things have to be considered," Sell says.

YUCCA MOUNTAIN is in trouble. Early this year, it was learned that
science data pertaining to the movement of water through the mountain
might have been falsified. The FBI and the Offices of Inspector
General for the Energy and Interior Departments are conducting
criminal investigations. The incursion of water through the tunnels
that would hold the spent fuel has been much debated and is key to
whether the waste can be isolated for the hundreds of thousands of
years that it will be lethal.

And last year, a federal court ruled that the radiation standard set
by the Environmental Protection Agency to protect the public at Yucca
Mountain is inadequate and illegal. The standard is fundamental to the
repository's design, and the court said EPA erred in basing the
standard on a 10,000-year compliance period rather than the time of
potential peak exposure, which is likely to occur in 300,000 to
480,000 years.

EPA is expected to repropose the standard late this summer or fall. It
is sure to be challenged by Nevada attorneys, who brought the
successful litigation that negated the past standard.

In addition, NRC has said that DOE has failed to adequately provide
information to the public. That failing, too, could delay the
commission's receipt of DOE's license application.

Although the repository has been held up for years, DOE officials
remain committed to preparing a construction application by year-end.
Considering what they face, meeting that target is doubtful.

NRC officials tell C&EN they are reluctant to estimate how quickly
they could process an application to license the facility once they
receive it, noting only that "the ball is in DOE's court."

Speaking at a Senate hearing on May 26, NRC Commissioner Edward
McGaffigan Jr. called the NRC license review process for Yucca
Mountain "the largest administrative proceeding in mankind," and he
predicted the application would be in the neighborhood of 4 million

Meanwhile, utilities and nuclear power advocates are pressing hard for
nuclear power and claim a "new renaissance" for this source of
electricity, mostly because of its ability to generate electricity
without CO2 emissions. The Nuclear Energy Institute (NEI), a nuclear
industry and utility trade association, points to a flood of favorable
news articles promoting nuclear power as a solution to global warming
and quoting advocates from Sen. John McCain (R-Ariz.) to Greenpeace
founder Patrick Moore to President George W. Bush.

The Administration upped its R&D budget for nuclear energy and is
providing funds to kick-start the next generation of nuclear power by
paying half the cost of processing applications for new plants.

PACK AND SHIP Eventually, each cask will be placed in a transportation
package and loaded onto a single railcar for shipment to a permanent
repository or an interim storage site. The site pictured was not

ALSO, SEVERAL NRC reforms in the 1990s will speed the regulatory
approval process. Utilities can now apply for an early site permit at
a specific location and separately seek NRC certification of a new
design. Once both these approvals are gained, a company can marry the
two and apply for a combined construction and operating license, a
simpler application with limited opportunity for public comment.
Utilities have begun the process by applying for three early site
permits and gaining design certification for two new reactor designs.
More are in the works.

NRC Chairman Nils J. Diaz says he expects five applications for
combined construction/operating licenses by 2007 or 2008. Two of them
will come from NuStart Energy Development, a coalition of nine energy
companies and two reactor manufacturers, which announced its intention
to file two construction/operating license applications with NRC by
2008. NuStart has identified six sites, all of which already have
operating reactors, and will include reactor designs by Westinghouse
and General Electric, two members of the consortium.

Marilyn C. Kray, NuStart president and vice president of Exelon
Generation, says NuStart hopes for NRC approval in 2010 and intends to
complete construction of a new reactor four years later. She estimates
that the costs to prepare the application will run to $520 million--
with half to be paid by U.S. taxpayers.

Energy Secretary Samuel W. Bodman goes further. He promised energy
executives at NEI's recent meeting that DOE will provide $500 million
each in "risk insurance" for construction of the first four nuclear
power plants that use new designs at new sites. The $2 billion would
help companies recover costs due to legal or regulatory delays.

All this aid is intended to shore up investors and give them the
confidence to lay down the billions of dollars needed for this long-
term and historically risky investment.

Meanwhile, radioactive waste continues to pile up at the existing 104
reactor sites, and more waste will come. Diaz says NRC has given 20-
year extensions to owners of 32 reactors and has 16 extensions
pending. He estimates that virtually all operating U.S. reactors will
apply to renew their licenses. These power plants are operating at
peak efficiency, and currently about 54,000 metric tons of waste is
piling up at operating sites, according to NEI figures. Something has
to give.

"We are not going to build new plants to create additional waste when
it hasn't been determined what is going to happen to the waste
generated by current plants," Kray says. "But we see aggressive action
going on in waste disposal, and we are not waiting for waste issues to
be resolved before addressing other issues." Her views are buttressed
by NEI officials who predict that, by 2008 or 2010, the nation will
have made significant progress on waste issues.

But Steve Kraft, NEI director of used-fuel management, adds that for
new plants to move ahead, the industry has to show that progress is
being made. "We don't need an operating waste facility, but we need to
be able to look people in the eye--your next-door neighbor, your
mother, and everybody else--and explain to them in a believable way
that we may not be moving waste yet, but we are going to get there,
and here is the progress we are making."

Kraft stresses that Yucca Mountain is the best solution, but adds:
"Interim shortage gives us a step. It allows us to move fuel earlier,
and we've got to start moving material. We should have started seven
years ago."

Hobson's approach in the DOE bill would require DOE to begin receiving
commercial spent fuel at one of its facilities next year. In
legislative report language, he lays out a scheme in which the federal
government would establish one or more interim sites at DOE facilities
in Hanford, Wash.; Savannah River, S.C.; or Idaho Falls, or find
another federal non-DOE site. The report says locating an interim
storage site at Yucca Mountain "made the most sense," but the Nuclear
Waste Policy Act prohibits siting it there until the facility receives
an operating license.

Hobson makes clear in report language and on the House floor that his
first choice is to complete the repository, but he notes that DOE is
not likely to open the facility until at least 2012 and says that
"actual operations might be delayed until the latter half of the next

He also notes the Yucca Mountain capacity problem. Although this could
be fixed by changing the law that set the repository size, Hobson
seeks to encourage DOE to develop fuel reprocessing and reuse the
spent fuel, thereby reducing the waste headed to the repository.

The bill appropriates $20 million to purchase transportation casks for
the spent fuel and to begin what the bill calls "early acceptance" of
commercial waste by 2006.

The bill easily cleared the House floor on a 416 to 13 vote. But the
debate illuminated several problems with gaining acceptance of interim
storage and reprocessing.

HOUSE MEMBERS from Washington, Idaho, and South Carolina strongly
opposed provisions that would bring commercial waste into their
states. They cited other laws prohibiting such actions. They stressed
repeatedly that the provisions were part of report language without
the force of law.

Several members warned that interim storage is likely to become
permanent storage as Yucca Mountain "recedes into the future." Rep.
John M. Spratt Jr. (D-S.C.) added, "We have served notice that we are
ready to do battle if someone wants to set up interim storage in South

Spratt and others also warned that fuel reprocessing generates
plutonium and voiced fears that it would encourage proliferation of
nuclear materials. Others noted the high costs of reprocessing, and
although usable fuel can be recovered through reprocessing, the waste
generated will still require disposal in a permanent high-level waste

The day after the bill passed the House, Diaz and McGaffigan told
senators at a hearing that it was simply uneconomical to reprocess
spent fuel in light of the cheap price of U.S. uranium and the high
costs and complications in reprocessing, as well as the proliferation
and security concerns.

The Senate will take up its appropriation soon, and although the
comparable appropriation committee is chaired by nuclear advocate Sen.
Pete V. Domenici (R-N.M.), his staff says the senator has not made
clear his views on Hobson's approach.

But is government support worth a half-dozen new nuclear plants with
the potential to reduce global warming? DOE's Sell says yes.

"We are interested in getting new designs certified, and we are really
interested in proving out the new regulatory process." Sell blames
much of the past cost overruns for the industry on regulatory
failures, which DOE hopes to amend. Industry hopes the activities of
the next decade will usher in an explosion of new power plants to
replace older reactors and expand U.S. reliance on nuclear energy.

Others disagree. Worldwide energy needs and global warming cry out for
fast action, say environmental groups, but nuclear power is not the
solution they promote.

Radioactive waste disposal is just one of many fundamental problems
facing nuclear power, says James MacKenzie, a physicist and senior
fellow with the World Resources Institute. He points to the
uncertainty of economics and risks and complications inherent in using
such a complex and expensive technology. Instead, he urges quick
action through greater energy efficiency and much more use of
renewable and noncarbon energy sources.

MacKenzie worries that nuclear power requires continuous government
subsidies, including liability insurance. Even then he doubts that
Wall Street will risk the large sums needed for nuclear power plants.

He warns that, historically, new energy technologies have taken 60
years to evolve. "This has been the record for wood to coal, coal to
oil, and oil to gas. For nuclear energy, the transition was
interrupted by a series of safety problems and a rush to build ever-
larger but untested reactors. Today, the world doesn't have this kind
of time."
