Nuclear Nonproliferation: NNSA's Threat Assessment Process Could Be Improved
GAO-16-118: Published: Oct 30, 2015. Publicly Released: Oct 30, 2015.
The National Nuclear Security Administration (NNSA)—a semiautonomous agency within the Department of Energy (DOE)—has used a variety of established methods in its “Over the Horizon” (OTH) initiative to assess potential proliferation threats, but the implementation of these methods had several limitations. NNSA used established methods in its OTH initiative, including: (1) a literature revi...
Indian Energy Development: Actions Needed to Address BIA Management Challenges
GAO-16-171T: Published: Oct 21, 2015. Publicly Released: Oct 21, 2015.
In its June 2015 report, GAO found that Bureau of Indian Affairs' (BIA) management shortcomings and other factors—such as a complex regulatory framework, limited capital and infrastructure, and varied tribal capacity—have hindered Indian energy development. Specifically, BIA's management has the following shortcomings:BIA does not have the data it needs to verify ownership of some Indian oil a...
Department of Energy: Transactions Involving USEC Inc. Since 1998
GAO-15-730: Published: Sep 10, 2015. Publicly Released: Oct 13, 2015.
The Department of Energy (DOE) has engaged with USEC Inc. (USEC) in 23 transactions since USEC was privatized in 1998 through July 1, 2015. The 23 transactions fall into the following six categories:Establishment of USEC. DOE engaged with USEC in 3 transactions to help establish the company as a private company. For example, from 1998 to 2003, DOE transferred enriched uranium, as required by the U...
Spent Nuclear Fuel: Legislative, Technical, and Societal Challenges to Its Transportation
GAO-16-121T: Published: Oct 1, 2015. Publicly Released: Oct 1, 2015.
Based on its prior work, GAO found three key challenges related to the transportation of spent nuclear fuel: legislative, technical, and societal.Legislative challenges . As GAO reported in November 2009, August 2012, and October 2014, DOE does not have clear legislative authority for either consolidated interim storage or for permanent disposal at a site other than Yucca Mountain. Specifically, p...
Pipeline Safety: Department of Transportation Needs to Complete Regulatory, Data, and Guidance Efforts
GAO-15-843T: Published: Sep 29, 2015. Publicly Released: Sep 29, 2015.
The Department of Transportation's (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) has begun but not completed efforts to improve pipeline safety in response to GAO's prior recommendations:Gathering pipelines : In 2012, GAO found that while gathering pipelines that are not regulated by PHMSA were generally considered to present less safety risk than other pipelines, PHMSA did...
Nuclear Nonproliferation: DOE Made Progress to Secure Vulnerable Nuclear Materials Worldwide, but Opportunities Exist to Improve Its Efforts
GAO-15-799: Published: Sep 23, 2015. Publicly Released: Sep 23, 2015.
The Department of Energy (DOE) achieved goals for two of its four key activities under the President's 2009 initiative to secure all vulnerable nuclear materials within 4 years. Specifically, from April 2009 through December 2013, GAO's analysis of DOE's records found that DOE exceeded its goal for removing or disposing of 1,201 kilograms of highly enriched uranium (HEU) or plutonium by more than...
Technology Assessment: Water in the Energy Sector: Reducing Freshwater Use in Hydraulic Fracturing and Thermoelectric Power Plant Cooling
GAO-15-545: Published: Aug 7, 2015. Publicly Released: Sep 8, 2015.
Waterless and water-efficient fracturing technologies such as gas-based fracturing or foams have been used to reduce the use of freshwater in hydraulic fracturing operations, although the main benefit is enhanced hydrocarbon recovery. The geologic formation characteristics of shale plays largely determine their use. According to experts GAO consulted, hydraulic fracturing operators are managing th...
Capitol Power Plant: Architect of the Capitol Should Update Its Long-term Energy Plan before Committing to Major Energy Projects
GAO-15-436: Published: Sep 3, 2015. Publicly Released: Sep 3, 2015.
The Architect of the Capitol (AOC) implemented many measures since 2008 to manage the energy-related costs of the Capitol Complex (the complex) and has opportunities to further manage these costs. AOC updated some of the Capitol Power Plant's (CPP's) production and distribution systems to reduce energy use and increase efficiency. AOC also implemented measures to reduce energy consumption in the c...
Modernizing the Nuclear Security Enterprise: NNSA Increased Its Budget Estimates, but Estimates for Key Stockpile and Infrastructure Programs Need Improvement
GAO-15-499: Published: Aug 6, 2015. Publicly Released: Aug 6, 2015.
The National Nuclear Security Administration's (NNSA) 25-year budget estimates for modernizing the nuclear security enterprise in its fiscal year 2015 budget materials total $293.4 billion, which is an increase of $17.6 billion (6.4 percent) compared with the prior year's materials.
