Feasibility and Incentives for the Consideration of Spent Fuel Operating Histories in the Criticality Analysis of Spent Fuel Shipping Casks
Analyses have been completed that indicate the consideration of spent fuel histories (''burnup credit'') in the design of spent fuel shipping casks is a justifiable concept that would result in cost savings and public risk benefits in the transport of spent nuclear fuel. Since cask capacities could be increased over those of casks without burnup credit, the number of shipments necessary to transport a given amount of fuel could be reduced.

CRS Report for Congress, Civilian Nuclear Spent Fuel Temporary Storage Options
The Department of Energy (DOE) is studying a site at Yucca Mountain, Nevada, for a
permanent underground repository for highly radioactive spent fuel from nuclear reactors,
but delays have pushed back the facility’s opening date to 2010 at the earliest. In the
meantime, spent fuel is accumulating at U.S. nuclear plant sites at the rate of about 2,000
metric tons per year. Major options for managing those growing quantities of nuclear spent
fuel include continued storage at reactors, construction of a DOE interim storage site near

Fission Product Benchmarking for Burnup Credit Applications
Fission Product Benchmarking for Burnup Credit Applications
Progress toward developing a technical basis for a cost-effective burnup credit methodology for
spent nuclear fuel with initial U-235 enrichment up to 5% is presented. Present regulatory
practices provide as much burnup credit flexibility as can be currently expected. Further progress
is achievable by incorporating the negative reactivity effects of a subset of neutron-absorbing
fission product isotopes. Progress also depends on optimizing the procedure for establishing the

Proposed Alternative Strategy for the Department of Energy's Civilian Radioactive Waste Management Program--A Task Force Report
In his January 12, 1993 letter to Senator Johnston, Secretary Watkins promised to develop a
conceptual revised program strategy for public review. The enclosed document represents the
final report of the Task Force on an Alternative Program Strategy that was established to fulfill
that commitment. The report incorporates refinements to the preliminary draft you received on
March 8, based on discussions with key people in the program.
In developing this alternative strategy, the Task Force has drawn on the extensive analyses of

Managing Nuclear Waste-A Better Idea, A Report to the U.S. Secretary of Energy
When Congress passed the Nuclear Waste Policy Act of 1982, it created the
Office of Civilian Radioactive Waste Management within the Department of
Energy to spearhead the implementation of this landmark legislation.
In Section 303 of the Act, however, Congress directed the Secretary of Energy
to study alternative approaches to managing the radioactive waste program, as
follows:
ALTERNATIVE MEANS OF FINANCING
SEC. 303. The Secretary shall undertake a study with respect to

Alternative Means of Financing and Managing the Civilian Radioactive Waste Management Program
This report is in response to the directive of the House Appropriations Subcommittee for Energy and Water
Development that the Department of Energy (DOE) update a 1984 report of alternative means of financing and
managing (AMFM) the Office of Civilian Radioactive Waste Management (OCRWM) in the DOE. The
President’s FY 2002 budget also stated: “DOE will submit to Congress an updated report regarding alternative
approaches to finance and manage the program by June 30, 2001[.] DOE will identify in this report models of
Managing Commercial High-Level Radioactive Waste
Managing Commercial High-Level Radioactive Waste
After more than 20 years of commercial nuclear power, the Federal
Government has yet to develop a broadly supported policy for fulfilling
its legal responsibility for the final isolation of high-level radioactive waste.
OTA's study concludes that until such a policy is adopted in law, there
is a substantial risk that the false starts, shifts of policy, and fluctuating support
that have plagued the final isolation program in the past will continue.
Final isolation-the last step in radioactive waste management-is intended

Factors Affecting Public and Political Acceptance for the Implementation of Geological Disposal
Factors Affecting Public and Political Acceptance for the Implementation of Geological Disposal
The main objective of this report is to identify conditions which affect public concern (either
increase or decrease) and political acceptance for developing and implementing programmes
for geologic disposal of long-lived radioactive waste. It also looks how citizens and relevant
actors can be associated in the decision making process in such a way that their input is
enriching the outcome towards a more socially robust and sustainable solution. Finally, it
aims at learning from the interaction how to optimise risk management addressing needs and

Environmental Impact Statement Comments, Management of Commercial High-Level and Transuranium-Contaminated Radioactive Waste
Environmental Impact Statement Comments, Management of Commercial High-Level and Transuranium-Contaminated Radioactive Waste
This report summarizes the results of EPA's review of the AEC
draft environmental statement, "Management of Commercial High-Level
and Transuranium-Contaminated Radioactive Waste" (WASH-1539). The
means by which high-level and long-lived radioactive wastes are
managed constitutes one of the most important questions upon which
the public acceptability of nuclear power, with its social and economic
benefits, will be determined. While the generation of power by
nuclear means offers certain benefits from the environmental viewpoint,
Phenomena and Parameters Important to Burnup Credit
Phenomena and Parameters Important to Burnup Credit
Since the mid-1980s, a significant number of studies have been directed at understanding the phenomena and
parameters important to implementation of burnup credit in out-of-reactor applications involving pressurizedwater-
reactor (PWR) spent fuel. The efforts directed at burnup credit involving boiling-water-reactor (BWR)
spent fuel have been more limited. This paper reviews the knowledge and experience gained from work
performed in the United States and other countries in the study of burnup credit. Relevant physics and analysis
Review and Prioritization of Technical Issues Related to Burnup Credit for LWR Fuel
Review and Prioritization of Technical Issues Related to Burnup Credit for LWR Fuel
This report has been prepared to review relevant background information and provide technical discussion that will help initiate a PIRT (Phenomena Identification and Ranking Tables) process for use of burnup credit in light-water reactor (LWR) spent fuel storage and transport cask applications. The PIRT process will be used by the NRC Office of Nuclear Regulatory Research to help prioritize and guide a coordinated program of research and as a means to obtain input/feedback from industry and other interested parties.
Safety Evaluation Report for Disposal Criticality Analysis Methodology Topical Report, Revision 0
Safety Evaluation Report for Disposal Criticality Analysis Methodology Topical Report, Revision 0
In January 1999, the U.S. Department of Energy (DOE)/Office of Civilian Radioactive
Waste Management (OCRWM) submitted the Disposal Criticality Analysis Methodology
Topical Report, Revision 0 (TR) to the U.S. Nuclear Regulatory Commission (NRC) for
review and approval. The TR presents an overall approach for consideration of postclosure
disposal criticality of commercial and defense high-level waste to be placed at
the proposed Yucca Mountain site. During the course of the review and interactions
Disposal Criticality Analysis Methodology Topical Report
Disposal Criticality Analysis Methodology Topical Report
The fundamental objective of this topical report is to present the planned risk-informed disposal criticality analysis methodology to the NRC to seek acceptance that the principles of the methodology and the planned approach to validating the methodology are sound. The design parameters and environmental assumptions within which the waste forms will reside are currently not fully established and will vary with the detailed waste package design, engineered barrier design, repository design, and repository layout.

ANSI/ANS-8.27-2008: Burnup Credit for LWR Fuel
This standard provides criteria for accounting for reactivity effects of fuel irradiation and radioactive decay in criticality safety control of storage, transportation, and disposal of commercial LWR UO2 fuel assemblies.
This standard assumes the fuel and any fixed burnable absorbers are contained in an intact assembly. Additional considerations could be necessary for fuel assemblies that have been disassembled, consolidated, damaged, or reconfigured in any manner.
