Summary of Group Development and Testing for Single Shell Tank Closure at Hanford

Integrating the Safety Evaluation for a Molten Salt Reactor Operation and Fuel Cycle Facility Application

“…Additional local processing of the used reactor vessel will depend on the amount of shielding necessary for transport to a final disposal site. The fuel salt space within the otherwise graphite-filled reactor vessel may be backfilled with grout to produce a long-term, stable, non-water-soluble waste form [83]. Overall, the used reactor vessel would be anticipated to be prepared to meet the requirements for near-surface disposal under the ongoing updating of 10 CFR 61.…”

Molten Salt Reactor Technical and Safety Considerations Outside of Guidance Documents

“…DOE has recognized this potential in its reconsideration of the disposal pathway for MSRE components and fuel salt residues. The experience gained in grouting waste tanks at the Hanford and Savannah River sites (Harbour 2005) that include highly radioactive residues shows the potential for used MSR SSCs to be encapsulated into stable, robust waste forms.…”
