Multi-Unit PSA Made Simple

The RiskSpectrum team has developed a method for making Multi-Unit PSA simple and scalable.

The scalability of the application is ensured using existing MCS lists for the single units.

As the failure combinations that are relevant for a single unit are represented by the single unit MCS list, the failure of several reactors should also be contained within those MCS lists.

What is the Impact?

Two large size PSA model were used simulating multi-unit CCFs and multi-unit human error dependencies.

As expected, an increase in the multi-unit release probability can be seen when multi-unit dependency is considered.

The only inputs necessary for the quantification were the MCS of the single units and a list of the multi-unit CCF events and human error dependencies.
