AP-600 PASSIVE SYSTEM I
T/H RELIABILITY
- Passive safety systems rely on natural forces, such as gravity and stored energy to perform their functions i
- 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 i
- Quantification of passive system TlH j
performance reliability is very difficult
