AP-600 PASSIVE SYSTEM T/H RELIABILITY

- Passive safety systems rely on natural forces, l such as gravity and stored energy to perform their functions

- Such forces are relatively small compared to pumped systems; their magnitude vary from one i scenario to another

- This requires assessment of the passive system TlH performance reliability

- Quantification of passive system TlH performance reliability is very difficult
