3. DESCRIPTION OF PROGRAM OR FUNCTION

PRISIM allows inspectors to quickly access probabilistic risk assessment (PRA) information and use it to update risk analysis results, reflecting a nuclear plant's status at any time. PRISIM also allows regulators to access PRA information and modify the information to assess the impact the changes may have on plant safety.

4. METHODS

The PRA results in PRISIM are based on core damage frequency. PRISIM does not incorporate the results of assessments of plant damage, containment responses, or public health consequences. Only point estimate PRA results are presented.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Many of the results in PRISIM do not reflect the effects of operator recovery actions. Recovery actions are actions that operators can take to maintain core cooling during accidents involving failures of the designed emergency cooling system.

6. TYPICAL RUNNING TIME

The code is highly interactive and response time is very quick.
