Subject:
Non-availability of fuel and funding to convert NBSR from HEU to LEU in 2025.
Ref: NBSR Facility License TR-5, Docket 50-184 Sir/Madam:
The NBSR facility is expected to convert from highly enriched uranium (HEU) to low enriched uranium (LEU) fuel in accordance with 10 CFR 50.64. At this time, the Department of Energy and the National Nuclear Security Administration (NNSA) have not developed and qualified a replacement LEU fuel acceptable to the Commission, and funds for such a conversion are not available. An updated LEU fuel development schedule released by NNSA proposes to convert the NBSR no earlier than 2030.
