Why GAO Did This Study
NNSA, a separately organized agency
within DOE, manages the Plutonium
Disposition program to dispose of
surplus weapons-grade plutonium by
burning it as MOX fuel—a mixture of
plutonium and uranium oxides—in
specially modified commercial nuclear
reactors. In 2012, DOE forecasted cost
increases of close to $3 billion over the
previous estimates for the program’s
two construction projects, the MOX
facility and the WSB for disposing of
waste from the MOX facility.
GAO was asked to review these cost
increases and the life-cycle cost
estimate. This report examines: (1)
drivers NNSA identified for the cost
increases; (2) the extent to which
NNSA analyzed underlying causes of
the cost increases; (3) steps NNSA
took to hold construction contractors
accountable for their role, if any, in the
cost increases; and (4) the extent to
which NNSA’s most recent estimates
met cost- and schedule-estimating best
practices. GAO reviewed NNSA’s draft
life-cycle cost estimate and contractor
estimates of the MOX project’s cost
and WSB schedule, compared the
estimates with cost- and schedule-
estimating best practices, and
interviewed DOE and NNSA officials.
What GAO Recommends
GAO is recommending, among other
things, that DOE conduct a root cause
analysis of the Plutonium Disposition
program’s cost increases and ensure
that future estimates of the program’s
life-cycle cost and cost and schedule
for the program’s construction projects
meet all best practices for reliable
estimates. DOE generally agreed with
GAO’s recommendations.
What GAO Found
The Department of Energy’s (DOE) National Nuclear Security Administration
(NNSA) identified various drivers for the close to $3 billion increase in the
estimated cost of the Plutonium Disposition program’s two construction
projects—the Mixed Oxide (MOX) Fuel Fabrication Facility and the Waste
Solidification Building (WSB). These drivers included DOE’s approval of the MOX
facility’s cost and schedule estimates before design was complete and schedule
delays in construction of the WSB. According to NNSA, the cost of critical system
components for the MOX facility averaged 60 percent higher than estimated as a
result of approval of estimates before design was complete.
NNSA has not analyzed the underlying, or root, causes of the Plutonium
Disposition program construction cost increases to help identify lessons learned
and help address the agency’s difficulty in completing projects within cost and
schedule, which has led to NNSA’s management of major projects remaining on
GAO’s list of areas at high risk of fraud, waste, abuse, and mismanagement.
DOE’s project management order requires that lessons learned be captured
throughout a project to, among other things, benefit future endeavors. NNSA
officials said that, because the order does not require a root cause analysis of
cost increases, NNSA decides on a case-by-case basis whether to conduct one.
Unlike a root cause analysis, the cost drivers NNSA identified provided few
details about why the drivers existed, such as DOE’s reasons for approving the
MOX facility’s cost and schedule estimates before the design was complete.
Without a root cause analysis, it is uncertain whether NNSA will be able to
accurately identify underlying causes of the increases to identify and implement
corrective measures and identify lessons learned to apply to other projects.
After determining that the performance of the contractors for the MOX facility and
WSB contributed to cost increases, NNSA took steps to hold the contractors
accountable by withholding fees specified under the contracts. In particular, as of
November 2013, NNSA withheld $45.1 million or close to one-third of the MOX
contractor’s fees, including fees tied to meeting the MOX project’s cost and
schedule estimates. In addition, NNSA withheld $7.7 million or about 40 percent
of the WSB contractor’s fees tied to various performance measures for the WSB,
such as completing construction milestones.
NNSA’s most recent estimates for the Plutonium Disposition program did not fully
reflect all the characteristics of reliable cost estimates (e.g., credible) and
schedule estimates (e.g., well-constructed) as established by best practices for
cost- and schedule-estimating, placing the program at risk of further cost
increases. For example: (1) NNSA’s draft April 2013 life-cycle cost estimate of
$24.2 billion for the overall program was not credible because NNSA did not
conduct an independent cost estimate to provide an unbiased test of whether the
estimate was reasonable. (2) Because the MOX contractor’s September 2012
proposal for increasing the cost of the MOX facility did not include a formal
analysis to examine the effects of changing assumptions, it was minimally
credible. (3) The WSB contractor’s February 2013 monthly update to its schedule
estimate was minimally well-constructed in that it contained activities that were
not properly tied with the start or end date of other activities, which could
potentially obscure the critical path determining the project’s completion date.

Plutonium is a man-made, radioactive element that poses a danger of
nuclear weapons proliferation and a risk to human health and the
environment. Under an agreement signed in 2000, the United States and
Russia have each pledged to dispose of at least 34 metric tons of surplus
weapons-grade plutonium no longer needed for defense purposes by
burning it as mixed oxide (MOX) fuel in specially modified commercial
nuclear reactors.
1
Once used and removed from a reactor, the plutonium
can no longer be readily used to make a nuclear weapon. The National
Nuclear Security Administration (NNSA), a separately organized agency
within the Department of Energy (DOE), manages the Plutonium
Disposition program. As part of this program, NNSA entered into separate
contracts for design and construction services for two facilities at DOE’s
Savannah River Site in South Carolina: (1) the MOX Fuel Fabrication
Facility for producing MOX fuel for nuclear reactors and (2) the Waste
Solidification Building (WSB) for disposing of liquid waste from the MOX
facility.
