Content:
Revision 4 - October 2003 36 Reactor coolant pumps (RCPs) contain a significant quantity of lubricating oil in proximity to extremely hot surfaces. A large combustible liquid fire inside containment could significantly threaten safe shutdown capability and would be extremely difficult to suppress. For these reasons, oil collection systems should be installed to safely contain oil leakage or discharge from ruptures. The specific design of oil collection systems should meet the guidelines in Regulatory Guide 1.189.
