PRA MODEL DEVELOPMENT

ERIN Engineering and Research, Inc. has unparalleled expertise in the development of probabilistic risk assessment (PRA) models. ERIN provides clients with a breadth and depth of experience built upon the development of models for over half of the U.S. nuclear units and participation in peer reviews of over 100 models.

ERIN is skilled in the development and application of Level 1, 2 and 3 PRAs to address the full range of potential hazards:

Internal Events
Internal Floods
Internal Fires
Seismic Events
High Winds
External Floods
Offsite Hazards, such as toxic gas releases and explosions
Other external hazards

Currently, there is significant interest in fire PRAs. ERIN has developed fire PRAs for nearly half of the plants in the U.S. Many of these are being done in conjunction with transitions to the risk-informed, performance-based fire protection requirements of NFPA-805.
