"Criticality HaZoP": Efficiently Evaluating Hazards of New or Revised Criticality Safety Evaluations
- Fluor Daniel Hanford, Inc., Richland, WA (United States)
The "Criticality HazOp" technique, as developed at Hanford's Plutonium Finishing Plant (PFP), has allowed for efficiencies enabling shortening of the time necessary to complete new or revised criticality safety evaluation reports (CSERs). For example, in the last half of 2007 at PFP, CSER revisions undergoing the "Criticality HazOp" process were completed at a higher rate than previously achievable. The efficiencies gained through use of the "Criticality HazOp" process come from the preliminary narrowing of potential scenarios for the Criticality analyst to fully evaluate in preparation of the new or revised CSER, and from the use of a systematized "Criticality HazOp" group assessment of the relevant conditions to show which few parameter/condition/deviation combinations actually require analytical effort. The "Criticality HazOp" has not only provided efficiencies of time but has brought to criticality safety evaluation revisions the benefits of a structured hazard evaluation method and the enhanced insight that may be gained from direct involvement of a team in the process. In addition, involved personnel have gained a higher degree of confidence and understanding of the resulting CSER product.
