To achieve this goal\, a multi-national laboratory (ANL\, INL\, PNNL\, and SRNL) project called Athena was established to steward plutonium processing competency. These l aboratories are working in tandem to retain the capability to process acti nides and leverage that knowledge for other applications.\n\nThis work has allowed researchers from various national laboratories to visit each othe r and participate in process demonstrations that use various solvent extra ction equipment. Therefore\, this talk will also briefly discuss some of S RNL’s contributions to the Athena program in using unique mini-mixer set tler with centrifugal contactors to process surrogate spent nuclear fuel.\ nBio\nJarrod Gogolski\, Ph.D.\nSenior Engineer\nSavannah River National La boratories\nDr. Jarrod Gogolski has primarily studied nuclear fuel dissol ution and solvent extraction flowsheets. He is a nuclear engineer by train ing\, with a strong radiochemistry focus - predominantly with Np and Pu se parations. He contributes to a variety of projects to support SRNL’s cor e competencies and missions: formation of solids from dissolved nuclear fu el\, recovery of uranium from U-10Mo fuel\, PuO2 interactions with fire ex tinguishants\, dissolution of U-Al alloy surrogates in a variety of inorga nic acids\, metal oxide dissolution in organic liquids\, etc.\n\nAbstract\ nThe H-Canyon facility at the Savannah River Site (SRS) is the only large- scale spent nuclear fuel (SNF) reprocessing plant still operating in the U nited States. However\, a recent pivot in the facility mission was made to expedite the disposal of SNF stored at the site.\n\nHighly enriched forei gn and domestic aluminum-clad research reactor fuels are dissolved\, down- blended with depleted uranium to less than 5 wt % uranium-235\, combined w ith a neutron absorbing poison\, neutralized\, and discarded to the SRS hi gh-level waste tank farm for subsequent vitrification in the Defense Waste Processing Facility. The Savannah River National Laboratory is supporting the direct disposal of the SNF in each area of the disposition flowsheet. Development of dissolution processes for the aluminum-clad fuels\, includ ing the prediction of the hydrogen generation rate from aluminum dissoluti on and the controls necessary to ensure the hydrogen concentration does no t exceed 25% of the lower flammability limit\, will be highlighted.\n\nRec ent work to evaluate the co-precipitation of neutron poisons and fissile m aterials during neutralization will also be discussed.\n\nA potential mech anism for the precipitation of fissile materials during the storage of sol utions containing SNF in H-Canyon tanks prior to neutralization will be pr oposed for future study.\nBio\nTracy Rudisill\nLaboratory Fellow\nSavannah River National Laboratories\nTracy Rudisill is a Laboratory Fellow in th e Separations and Actinide Science group at the Savannah River National La boratory (SRNL) with 39 years of experience in nuclear materials R&\;D. In this position\, Tracy has performed R&\;D activities associated wit h most uranium\, neptunium\, plutonium\, americium\, and curium processing activities at the Savannah River Site (SRS). His research focuses on sepa ration processes associated with the nuclear fuel cycle and processes used to recover\, purify\, and isolate actinide materials. Tracy works as a pr incipal investigator for the Department of Energy’s (DOE’s) Nuclear En ergy Fuel Cycle Technologies program\, leads both the SRNL aqueous process ing support provided to potential molybdenum-99 producers through the DOE National Nuclear Security Association’s (NNSA’s) national laboratory a ssistance program and the aqueous process development for the NNSA’s Hig h-Performance Research Reactor fuel scrap recovery program. Tracy also lea ds the team of SRNL researchers who support used fuel processing in the SR S H-Canyon facility. Tracy serves as the SRNL technical lead for the Athen a project\, which is supported by the DOE NNSA as a Nuclear Nonproliferati on Stewardship program to mentor younger staff members in technology areas associated with the recovery of actinide materials from spent nuclear fue ls.
