The Department of Energy is seeking a contractor to perform a leak test demonstration of a representative spent nuclear fuel transportation canister, as part of its operations planning for a federal Consolidated Storage Facility (CSF). The procurement involves system design, test planning, execution, and reporting to support the development of helium leakage rate testing, which is crucial for verifying the containment integrity of spent nuclear fuel canisters during transport. This initiative is significant as it addresses the need for reliable testing methods under off-normal transportation conditions, ensuring safety and compliance with Nuclear Regulatory Commission regulations.
