A single point failure analysis was performed on major equipment of four facilities of the Accelerated Transuranic Waste Remediation Program at the DOE Savannah River Site. The objective was to identify critical equipment whose failure can stop work and result in unacceptable schedule delay and repair cost and to recommend pre‐emptive actions to reduce these impacts. It was an expert based analysis performed by teams of subject matter experts following a systematic process to ensure that all major equipment is included and cost effective recommendations are developed and prioritized. Eighty five systems were analyzed, and two were found to present a potential for single point failure. Acquiring replacement parts for the three most critical components of each system would considerably reduce failure impacts and, therefore, was recommended. This study demonstrates the power of utilizing collective professional judgment of teams of subject matter experts in a systematic process to promptly identify failure vulnerability and reduce its impacts.
