Safety and Packaging Analyses
Provided independent review of and confirmatory analyses for safety analysis reports for packaging (SARPs) for various component shipping containers used at the Y-12 plant. This work was performed using the SCALE code system on the classified mainframe computers at Y-12.
Provided the shielding analysis chapter for a SARP for a RTG shipping assembly and associated conveyance for the Mound Laboratory. This included using the ANISN computer code for the neutron shielding analysis and ISOSHLD code for the photon shielding study. Both of these models were confirmed against physical measurements made by the staff at Mound.
Provided independent technical review of the shielding and criticality chapters of an Onsite Safety Assessment (analogous to a SARP) performed by the Savannah River Site Packaging and Transportation Group for the LR-56S Radioactive Liquid Transfer Package. This package is a modified version of a French design that will be used to transfer large quantities of neptunium- and plutonium-bearing solutions on the Savannah River Site. These reviews included confirmatory calculations made using the MCNP-4A and KENO-Va computer codes.
Provided shielding analyses in support of SARPs for the Sandia National Laboratory.
Performed review and independent confirmatory analyses of SARPs prepared for the Los Alamos model FL container. This effort included resolution of conflicts between analyses performed for the same container by different groups. DOE Quality Assurance specifically complemented SRA’s procedures for performance and documentation of calculations.
Provided criticality safety engineering in support of licensing efforts for the K-25 site Toxic Substance Control Act (TSCA) Incinerator and related support facilities.
