Title: Use of the HAZOP technique for compliance to DOE Order 5480.21, unreviewed safety questions

Abstract

As part of the Waste Isolation Pilot Plant (WIPP) test program, contact-handled transuranic (CH TRU) waste forms were to be measured for gas generation in a controlled environment. One of these programs was to involve a system to circulate humid air saturated with brine through a CH TRU waste loaded container called a Humid Waste Bin. The program involves evaluation of hazards associated with the chemical processes and those due to the presence of radioactive materials in the waste. A series of Hazard and Operability Studies (HAZOPs) was performed to: (1) Identify design characteristics, potential hardware failures, or human errors associated with the design of the Humid Waste Bin Test Program, and (2) Determine hazardous or unacceptable conditions, (i.e., injuries, fatalities, loss of equipment, environmental incidents or loss of test data.) To derive the most benefit from the HAZOPs, the WIPP staff utilized an integrated approach with the engineering design. A preliminary HAZOP was conducted at the 50% design stage and a final HAZOP at the 95% design stage. The preliminary HAZOP served as a primary vehicle for identification of potential hazards. Discussions on hazard mitigation features, an integral part of the HAZOP, identified both the existing mitigation features asmore » well as those needed to ensure a safe and sound design; it also identified responsible organizations for executing the recommended actions. DOE Order 5480.21, Unreviewed Safety Questions, requires that a DOE contractor take actions for systematic identification, evaluation, and disposal of unreviewed safety questions. The HAZOPs conducted at WIPP helped to show there was no unidentified safety questions for the planned Humid Waste Bin Test Program. This particular test with CH TRU waste was cancelled in December 1993.« less
