National Spent Nuclear Fuel Strategy Meeting April 15, 2009 SRS Spent Nuclear Fuel Acceptance Criteria Dawn Gillas Federal Program Manager Nuclear Material Programs Division DOE-SR
SRS SNF Acceptance Criteria • Environmental Impact Statements • L-Area Authorization Basis • Spent Fuel Engineering Review • DOE Appendix A and B • Nuclear Criticality Safety Review
Environmental Impact Statement DOE/EIS-203F – Programmatic SNF Management EIS, • Existing and newly generated Al-clad spent nuclear fuel will be consolidated at SRS • FRR and DRR Al-clad fuel • INL Al-clad fuel
Environmental Impact Statement DOE/EIS-0218F – FRR SNF EIS • Applies solely to the following types of reactor fuels: • Foreign research reactor spent nuclear fuel which contains uranium enriched in the United States. • Al-clad fuel where the uranium-235 content is >/= 20 percent by weight • Fuel meat configured as U-Al alloy, uranium-oxide,or uranium-aluminide. • Fuels containing significant quantities of uranium-233 are excluded • Al-clad fuel where the uranium-235 content is </= 20 percent by weight • Fuel meat configured as uranium-silicide, uranium-oxide, or uranium-aluminide.
L-Area Authorization Basis • All fuel received and stored in accordance with: • Technical Safety Requirements: S-TSR-L-00002, Technical Safety Requirements, Savannah River Site, L-Material Storage Facilities (U) • Documented Safety Analysis: WSRC-SA-2004-00002, L-Area Material Storage Facilities, Documented Safety Analysis (U)
Spent Fuel Engineering Review • WSRC-TR-98-00199 – Foreign and Domestic Research Reactor Fuel Program Instructions for Engineering Reviews of SNF Receipts and Storage. • Reactor operators prepare and submit Appendix A data, drawings, fuel cycle history, pre and post fuel irradiation data. • Spent Fuel Engineering performs a consistency check of the data by calculation. • ANL/RERTR/TM-26 – Nuclear Mass Inventory, Photon Dose rate and Thermal Decay Heat of Spent Research Reactor fuel Assemblies. • Review of Nuclear Criticality Safety Evaluation and Nuclear Safety Data Sheet
DOE Appendix A • Appendix A: Spent Nuclear Fuel Acceptance Criteria • Detailed Fuel Element and Fuel Assembly Data • Fuel fabrication drawings • Fuel condition statement • Summary of Reactor fuel cycle • Pre and Post irradiation radionuclide data • Used for FRR and DRR fuel data (no “contract” for DRR)
DOE Appendix B • Appendix B: Transportation (Cask) Acceptance Criteria • FRR only • Shipment and transportation package requirements • Criteria for identification of Failed Fuel, Degraded Fuel or Materially Damaged Fuel • Radionuclide (SIP) test for failed fuel • Radiological survey requirements
Nuclear Criticality Safety Review • WSMS-CRT-01-0116 – Nuclear Criticality Safety Methods Manual • Nuclear Criticality Safety Evaluation • Nuclear Safety Data Sheet • Fuel is critically safe for cask unloading and storage • Analysis can be cask specific – unload cask underwater, unload cask using the Shielded Transfer System, unload cask in air by hand (fresh or zero burn up) • Storage system specific • Safe for on site transfer • Nuclear Safety Data Sheet Approved by DOE-SR
