In recent times, PSA is more broadly being applied to support numerous applications and risk informed decisions on various design related, operational and regulatory issues. The expanded use of PSA in the integrated risk informed decision making process requires that the PSA possess certain features to ensure its technical consistency and quality. The features of a PSA that are necessary to support specific applications vary with the application. It is therefore essential that a comprehensive PSA model be developed addressing all the features so that a wide range of PSA applications can be carried out.
Consultants at RELSAFE are capable of providing full scope services associated with PSA Applications and Risk Informed Decision Making at various life stages of the plant. Some of these applications are listed below:
- Overall plant safety (understand main contributors to risk)
