Tuesday, January 6, 2026 - RTE

Proposals must be submitted by 4 p.m. MT / 6 p.m. ET Thursday, Jan. 29. This user access allocation process offers an avenue for researchers to perform irradiation effects studies of limited scope on nuclear energy relevant fuels and materials using NSUF facilities. Completion of Rapid Turnaround Experiment (RTE) projects should be completed within nine months of award. Prospective researchers may request samples from the NSUF Nuclear Fuels and Materials Library. RTE proposals are reviewed and evaluated for technical merit, relevancy and feasibility.
