Report On External Criticality of Plutonium Waste Forms In A Geologic Repository
Report On External Criticality of Plutonium Waste Forms In A Geologic Repository
This report presents the analyses and results for the potential occurrence of external criticality events which could result from plutonium waste forms emplaced in a geologic repository similar to the one being developed at Yucca Mountain. The analyses evaluate both the MOX spent fuel and the immobilized plutonium waste forms in a repository if the waste package has degraded and if the fissile material has migrated to the invert and out into the far-field.
Initial Radionuclide Inventories
Initial Radionuclide Inventories
The purpose of this analysis is to provide an initial radionuclide inventory (in grams per waste package) and associated uncertainty distributions for use in the Total System Performance Assessment for the License Application (TSPA-LA) in support of the license application for the repository at Yucca Mountain, Nevada. This document is intended for use in postclosure analysis only.

Transportation System Requirements Document Revision 5
The Nuclear Waste Policy Act of 1982 (NWPA), as amended, authorized the DOE to develop and manage a Federal system for the disposal of Spent Nuclear Fuel (SNF) and High-Level Radioactive Waste (HLW). The Office of Civilian Radioactive Waste (OCRWM) was created to manage acceptance, transportation and disposal of SNF and HLW in a manner that protects public health, safety, and the environment; enhances national and energy security; and merits public confidence.
ANS Position Statement: Licensing of Yucca Mountain as a Geological Repository for Radioactive Wastes
ANS Position Statement: Licensing of Yucca Mountain as a Geological Repository for Radioactive Wastes
The American Nuclear Society (ANS) supports (1) the development and use of geological
repositories for disposal of high-level radioactive wastes and (2) expeditious processing of the
Yucca Mountain license application in an open, technically sound manner. Geological disposal
means placing the wastes hundreds of feet underground and far from the biosphere. The U.S.
Nuclear Regulatory Commission (NRC) is following a legislatively well-defined regulatory
process to evaluate the safety of the proposed Yucca Mountain Site to meet both the scientific
Key Issues Associated with Interim Storage of Used Nuclear Fuel
Key Issues Associated with Interim Storage of Used Nuclear Fuel
The issue of interim storage of used (spent)1 fuel is dependent on a number of key factors, some
of which are not known at this time but are the subject of this study. The first is whether or not
the Yucca Mountain Project continues or is cancelled such that it may be able to receive spent
fuel from existing and decommissioned nuclear power stations. The second is whether the United
States will pursue a policy of reprocessing and recycling nuclear fuel. The reprocessing and
Drift-Scale THC Seepage Model
Drift-Scale THC Seepage Model
The purpose of this report is to document the thermal-hydrologic-chemical (THC) seepage model and model simulations. The simulations predict the composition of fracture water that could potentially seep into repository emplacement drifts and the composition of the associated gas phase. The THC seepage model is not used to feed the total system performance assessment (TSPA) for the license application (LA).

Dear Co-Chairs Hamilton and Scowcroft:
The Obama Administration believes that nuclear energy has an important role to playas America moves to a clean energy future. One of my goals as Secretary of Energy is to help restart America's nuclear industry, creating thousands of new jobs and new export opportunities for the United States while producing the carbon free energy we need to power America's economy.
Closing Yucca Mountain: Litigation Associated with Attempts to Abandon the Planned Nuclear Waste Repository
Closing Yucca Mountain: Litigation Associated with Attempts to Abandon the Planned Nuclear Waste Repository
Passed in 1982, the Nuclear Waste Policy Act (NWPA) was an effort to establish an explicit statutory basis for the Department of Energy (DOE) to dispose of the nation’s most highly radioactive nuclear waste. The NWPA requires DOE to remove spent nuclear fuel from commercial nuclear power plants, in exchange for a fee, and transport it to a permanent geologic repository or an interim storage facility before permanent disposal. Defense-related high-level<br>waste is to go into the same repository.
Disposal of High-Level Radioactive Wastes in a Proposed Geologic Repository at Yucca Mountain, Nevada; Final Rule
Disposal of High-Level Radioactive Wastes in a Proposed Geologic Repository at Yucca Mountain, Nevada; Final Rule
The Nuclear Regulatory Commission (NRC) is publishing licensing criteria for disposal of spent nuclear fuel and high-level radioactive wastes in the proposed geologic repository at Yucca Mountain, Nevada. As mandated by law, this final rule changes the Commissions technical requirements and criteria, as necessary, to be consistent with final environmental standards for Yucca Mountain issued by the U.S. Environmental Protection Agency (EPA).
Public Health and Environmental Radiation Protection Standards for Yucca Mountain, Nevada; Proposed Rule
Public Health and Environmental Radiation Protection Standards for Yucca Mountain, Nevada; Proposed Rule
We, the Environmental Protection Agency (EPA), are proposing to revise certain of our public health and safety standards for radioactive material stored or disposed of in the potential repository at Yucca Mountain, Nevada. Section 801(a) of the Energy Policy Act of 1992 (EnPA, Pub. L. 102Ð 486) directed us to develop these standards. These standards (the 2001 standards) were originally promulgated on June 13, 2001 (66 FR 32074).
On Petitions for Review of Orders of the EPA, the DOE, and the NRC
On Petitions for Review of Orders of the EPA, the DOE, and the NRC
In sum, we vacate 40 C.F.R. part 197 to the extent that it incorporates a 10,000-year compliance period because, contrary to EnPA section 801(a), that compliance period is not<br> "based upon and consistent with " the recommendations of the National Academy of Sciences. The remaining challenges to the EPA rule are without merit. We vacate the NRC rule insofar as it incorporates EPAÕs 10,000-year compliance period. In all other respects, we deny NevadaÕs petition for review challenging the NRC rule.

Nuclear Waste Management: Key Attributes, Challenges, and Costs for the Yucca Mountain Repository and Potential Alternatives
Nuclear Waste Management: Key Attributes, Challenges, and Costs for the Yucca Mountain Repository and Potential Alternatives
The Yucca Mountain repository is designed to provide a permanent solution for managing nuclear waste, minimize the uncertainty of future waste safety, and enable DOE to begin fulfilling its legal obligation under the Nuclear Waste Policy Act to take custody of commercial waste, which began in 1998. However, project delays have led to utility lawsuits that DOE estimates are costing taxpayers about $12.3 billion in damages through 2020 and could cost $500 million per year after 2020, though the outcome of pending litigation may affect the government’s total liability.
