The Interim Staff Guidance on burnup credit issued by the U.S. Nuclear Regulatory Commission's Spent Fuel Project Office recommends restricting the use of burnup credit to assemblies that have not used burnable absorbers. This restriction eliminates a large portion of the currently discharged spent fuel assemblies from cask loading, and thus severely limits the practical usefulness of burnup credit.
The purpose of this report is to provide an estimate of potential waste inventory and waste form
characteristics for the DOE UNF and HLW and a variety of commercial fuel cycle alternatives in order to
support subsequent system-level evaluations of disposal system performance. This report is envisioned as
a “living document” which will be revised as specific alternative fuel cycles are developed
The Materials Characterization Center (MCC) at Battelle Pacific Northwest Laboratory (PNL) has the responsibility to select appropriate spent fuel Approved Testing Materials (ATMs) and to characterize, via hot-cell studies, certain detailed properties of the discharged fuel. The purpose of this report isto develop a collective description of the entire spent fuel inventory in terms of various fuel properties relevant to ATMs using information available from the Characteristics Data Base (CDB), which is sponsored by the U.S.
Background The U.S. Department of Energy (DOE) established medical screening
programs at the Hanford Nuclear Reservation, Oak Ridge Reservation, the Savannah
River Site, and the Amchitka site starting in 1996.Workers participating in these programs
have been followed to determine their vital status and mortality experience through
December 31, 2004.
Methods A cohort of 8,976 former construction workers from Hanford, Savannah River,
Oak Ridge, and Amchitka was followed using the National Death Index through December
This report evaluates the potential for directly disposing of licensed commercial Dual Purpose
Canisters (DPCs) inside waste package overpacks without reopening. The evaluation considers
the principal features of the DPC designs that have been licensed by the Nuclear Regulatory
Commission (NRC) as these relate to the current designs of waste packages and as they relate to
disposability in the repository. Where DPC features appear to compromise future disposability,
those changes that would improve prospective disposability are identified.

The purpose of the Foreign Research Reactor (FRR) Spent Nuclear Fuel (SNF) Shipments Institutional Program was to meet the goals and commitments of the Implementation Strategy Plan for the FRR SNF Shipments. This program provided a systematic approach to planning, implementing, evaluating, and validating preparedness for the first west coast shipment of SNF from Asian countries to the Idaho National Engineering and Environmental Laboratory (INEEL).
This report is part of a report series designed to document benchmark-quality radiochemical assay data
against which computer code predictions of isotopic composition for spent nuclear fuel can be validated
to establish the uncertainty and bias associated with the code predictions. The experimental data analyzed
in the present report were acquired from two international programs: (1) ARIANE and (2) REBUS, both
coordinated by Belgonucleaire. All measurements include extensive actinide and fission product data of
Consumers Energyhas fulfilled its promise to restore the Big Rock Point nuclear plant site to a greenfield — free for unrestricted use by new generations of Michigan residents.
The significance of this small 67-megawatt nuclear energy pioneer — tucked away along northwest Michigan’s picturesque shoreline — will long be remembered as a shining example of operational excellence and good citizenship.
The purpose of this analysis report is to document the screening decisions and technical bases for inclusion or exclusion of each FEP identified as relevant to the TSPA and the Yucca Mountain disposal system, in accordance with the regulatory screening criteria identified for the Yucca Mountain Site.
Disposal of radioactive waste from nuclear weapons production and power generation has
caused public outcry and political consternation. Nuclear Wastes presents a critical review
of some waste management and disposal alternatives to the current national policy of
direct disposal of light water reactor spent fuel. The book offers clearcut conclusions for
what the nation should do today and what solutions should be explored for tomorrow.

U.S Court of Federal Claims Senior Judge James F. Merow issued a favorable ruling on September 30, 2006 for the three former Yankee nuclear power plants in their litigation with the federal government over its failure to remove used nuclear fuel from the three New England sites. Yankee Vice- President and Chief Financial Officer Michael Thomas said, “While the Court’s decision will need to be reviewed and evaluated, the Yankee companies’ initial reaction to the monetary award is very positive.
The Connecticut Yankee Atomic Power Company (CY) today announced that it has been notified by the U.S. Nuclear Regulatory Commission (NRC) that its former plant site has been decommissioned in accordance with NRC procedures and regulations. The NRC has formally approved Connecticut Yankee’s Final Status Survey Reports in accordance with the License Termination Plan. The site under the federal license is now reduced to the approximately 5 acres surrounding the Independent Spent Fuel Storage Installation site.
The search for sites for radioactive waste management (RWM) facilities attracts attention from implementers, government bodies, local communities, and the public at large. Facility siting processes, in general, tend to be marred by conflicts, disagreements, and delays.
The Interim Staff Guidance on burnup credit (ISG-8) issued by the United States Nuclear Regulatory
Commission’s (U.S. NRC) Spent Fuel Project Office recommends restricting the use of burnup credit to
assemblies that have not used burnable absorbers. This recommended restriction eliminates a large portion
of the currently discharged spent fuel assemblies from cask loading, and thus severely limits the practical
usefulness of burnup credit. In the absence of readily available information on burnable poison rod (BPR)
This report highlights the findings and conclusions of the Blue Ribbon Commission on America’s Nuclear Future (BRC) and presents recommendations for consideration by the Administration and Congress, as well as interested state, tribal and local governments, other stakeholders, and the public.
An Act to provide for the development of repositories for the disposal of high-level radioactive waste and spent nuclear fuel, to establish a program of research, de- velopment, and demonstration regarding the disposal of high-level radioactive waste and spent nuclear fuel, and for other purposes.
This document summarizes DOE’s commercial nuclear energy RD&D program based on a R&D roadmap and on DOE/NE’s budget request for fiscal year 2011. The roadmap is written at a high level and is mostly qualitative in terms of activities, milestones and decisions to be made and does not contain budget information. The fiscal year 2011 budget request contains more specific and detailed information on activities, milestones, decisions, and budgets but only for fiscal year 2011 and the two preceding fiscal years.

The management of spent nuclear fuel (SNF) and defense high level waste (HLW) is a complex sociotechnical
systems challenge. Coordinated, reliable, and safe performance will be required over very long
periods of time within evolving social and technical contexts. To accomplish these goals, a waste
management system will involve a host of facilities for interim storage and longterm disposal, a
transportation infrastructure, and research and development centers. The complexity of SNF and HLW

This manual discusses the routines to estimate radiological doses from normal operations used in
Version 6.0 of the Total System Model (TSM) as described in the TSM User Manual prepared
for the U.S. Department of Energy (DOE) by Bechtel SAIC Company (BSC) (BSC 2007a). The
TSM estimates doses during the simulation of the Civilian Radioactive Waste Management
System (CRWMS) mission. The TSM is not intended to provide a robust dose evaluation tool
and should only be used for relative comparisons of scenarios to general understand if doses are
