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.
Axial Burnup Profile Database for Pressurized Water Reactors
Axial Burnup Profile Database for Pressurized Water Reactors
The data were obtained directly from utilities whose reactors represent the range of commercial PWR fuel lattices. The work was performed by Yankee Atomic Electric for Sandia National Laboratory. All axial burnup profiles were calculated from 3-D depletion analyses of the core configuration. The organizations and utilities providing axial burnup profiles for the database used different model codes for the 3D-depletion calculations. The model codes used were: SIMULATE-3, NEMO, ANC, and PRESTO-II. Cross-section inputs describing the assemblies are derived from assembly lattice calculations.
Regulations for the Safe Transport of Radioactive Material - 2005 Edition
Regulations for the Safe Transport of Radioactive Material - 2005 Edition
101. These Regulations establish standards of safety which provide an
acceptable level of control of the radiation, criticality and thermal hazards to
persons, property and the environment that are associated with the transport of
radioactive material. These Regulations utilize the principles set forth in both
the “Radiation Protection and the Safety of Radiation Sources”, Safety Series
No. 120 [1] and the “International Basic Safety Standards for Protection
against Ionizing Radiation and for the Safety of Radiation Sources”, Safety
ANSI/ANS-8.27-2008: Burnup Credit for LWR Fuel
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.
Criticality Analysis of Assembly Misload in a PWR Burnup Credit Cask
Criticality Analysis of Assembly Misload in a PWR Burnup Credit Cask
The Interim Staff Guidance on burnup credit (ISG-8) for spent fuel in storage and transportation casks, issued by the Nuclear Regulatory Commission’s Spent Fuel Project Office, recommends a burnup measurement for each assembly to confirm the reactor record and compliance with the assembly burnup value used for loading acceptance. This recommendation is intended to prevent unauthorized loading (misloading) of assemblies due to inaccuracies in reactor burnup records and/or improper assembly identification, thereby ensuring that the appropriate subcritical margin is maintained.

Identification of Sites within the Palo Duro Basin: Volume 2--Palo Duro Location B
This three-volume document narrows to two sites for continued investigations for potential nuclear waste repository sites in the Palo Duro Basin of the Texas Panhandle. Volume 1 narrows a site previously identified in Deaf Smith County, Texas; Volume 2 narrows a site previously identified in Swisher County, Texas; and Volume 3 contains responses to comments received regarding the drafts of Volumes 1 and 2 (BMI/ONWI-531).<br/>These volumes discuss the methodology and logic used as well as the results that narrowed these sites.

DOE Announces Three Potential Sites for Proposed Monitored Retrievable Storage Facility
Press Release - Three potential candidate sites for a facility to handle, package and temporarily store spent nuclear fuel have been identified by the U.S. Department of Energy (DOE). If approved by Congress, the facility would receive spent fuel from commercial nuclear power plants nationwide and package it for delivery to a permanent repository for final disposal.
