Facility Safety Assessment

ARSS staff are experienced in conducting a variety of safety assessments for commercial nuclear power plants, advanced reactors, research reactors, and nuclear support facilities including probabilistic risk assessments (PRAs) and failure modes and effects analyses (FMEAs). Our staff pioneered the use of PRA techniques to quantify the significance of events considered to be precursors to potential core damage accidents for NRC. We recently provided support to NRC in evaluating the PRA as submitted as part of a preapplication licensing review of an advanced CANDU reactor, the ACR-700. We have developed a tool for applying PRA techniques during the design phase for reactor systems, the Risk-Based Design Optimization Tool (RBOT), that has been applied to make design improvements relative to safety and reliability for both space fission power systems and Westinghouse's IRIS small reactor design.

We have and continue to be integrally involved in assessing safety issues for lunar fission power systems as well as nuclear thermal propulsion systems for NASA.
