Abstract
In this report, preliminary requirements are outlined for site PSA documentation, model management and computation. First, overall requirements for site PSA are developed. Second, it is specified what information needs to be documented in different site PSA analysis steps. Third, requirements for a multi-unit dependency database and PSA model management process are listed. Finally, requirements for computation results are specified.
The requirements were mainly outlined based on method development that focused on level 1 PSA. When level 2 PSA and other radioactive sources than the fuel in the reactor core are included in the scope, some additional requirements might be needed. In addition, the overall requirements only consider PSA applications on a general level. It is therefore expected that the set of requirements will be updated when more research and development work is completed and after gaining experience from site PSA work. Guidelines for site PSA model management should also be prepared.
