Probabilistic risk assessment success criteria using melcor models

Added: Mar 23, 2011 2:04 pm The MELCOR computer program has historically been used for performance of deterministic light-water reactor severe accident analysis. Recently, MELCOR has been used for a number of other purposes including high-temperature gas reactor analysis, spent fuel pool analysis, and light-water reactor design-basis confirmatory analysis. In addition, MELCOR has recently been employed for probabilistic risk assessment (PRA) success criteria analysis, both at the NRC and elsewhere. An example of this usage is NUREG-1953, "Confirmatory Thermal-Hydraulic Analysis to Support Specific Success Criteria in the Standardized Plant Analysis Risk Models - Surry and Peach Bottom."

The objective of this contract is to obtain contractor technical assistance in: 1) Existing Model Upgrade and Maintenance and New Model Development, 2) Quick-Turn-Around Calculations to Support Emergent Issues, 3) Investigation of Underlying Modeling Assumptions, 4) Support for Comparative Analysis with the Modular Accident Analysis Package, 5) Scoping of Success Criteria Issues for a New Site Level 3 PRA and 6) Technical Assistance and Draft NUREG/CR Development.

The performance period will be from day of award (estimated June 2011) through two years.
