Single failure analysis for several modification projects

Westinghouse pressurised water reactor, Ringhals AB

Application: Operational power plant.
Project scope: Safety analysis.
Client: Ringhals AB, Väröbacka, Sweden.

Our work with Ringhals AB involves their facility that uses a pressurised water reactor of Westinghouse design. We are helping to solve safety deviations by performing verification analysis and evaluating safety upgrades for plant modifications. We have performed single failure analysis for several modification projects, including a modified auxiliary feedwater system, isolation valve function, component cooling system and residual heat removal / containment spray systems.
