Measurements of Water and B4C Content of Rackable Can Storage Boxes for HEU Storage at the HEUMF at the Y-12 National Security Complex

Description: Extensive measurements at the Oak Ridge National Laboratory (ORNL) with BoroBond{trademark} blocks of varying thickness, natural boron carbide (B{sub 4}C) content, and water content, and with a simplified mockup of the Rackable Can Storage Box (RCSB) of fixed natural B{sub 4}C and water content, have led to a method of quantifying the water content of RCSBs by fast neutron time-of-flight transmission measurements (NMIS)* and quantifying the B{sub 4}C content with gamma ray spectrometry assuming… more

235U Holdup Measurements in Three 321-M Exhaust HEPA Banks

Description: The Analytical Development Section of Savannah River National Laboratory (SRNL) was requested by the Facilities Disposition Division to determine the holdup of enriched uranium in the 321-M facility as part of an overall deactivation project of the facility. The 321-M facility was used to fabricate enriched uranium fuel assemblies, lithium-aluminum target tubes, neptunium assemblies, and miscellaneous components for the production reactors. The results of the holdup assays are essential for det… more

A multi-attribute utility decision analysis for treatment alternatives for the DOE/SR aluminum-based spent nuclear fuel

Description: A multi-attribute utility analysis is applied to a decision process to select a treatment method for the management of aluminum-based spent nuclear fuel (Al-SNF) owned by the US Department of Energy (DOE). DOE will receive, treat, and temporarily store Al-SNF, most of which is composed of highly enriched uranium, at its Savannah River Site in South Carolina. DOE intends ultimately to send the treated Al-SNF to a geologic repository for permanent disposal. DOE initially considered ten treatment … more

Sensitivity of Subcritical Measurement Simulations to Neutron Cross-Section Data

Description: Evaluation of nuclear data typically includes validation of the data through computation of k{sub eff}for critical assemblies. The sensitivity of the computed k{sub eff} values to the nuclear data is used as an indicator in determining the adequacy of an evaluation. Subcritical measurements offer an alternative to critical experiments as a means to evaluate nuclear data through direct computation of subcritical measurement quantities. In some instances, the subcritical measurement quantities ar… more
