erpressurization event should include additional analyses DRAFT Rev. 3 - April 1996 5.2.2-12 considering inadvertent system initiation/actuation or provide justification to show that existing analyses bound such an event. 10. If pressure relief is from a low pressure system, not normally connected to the primary 54 system, the overpressure protection function should not be defeated by interlocks which would isolate the low pressure system from the primary coolant system.

Item Source Description 1. Editorial A punctuation error that caused confusion regarding the meaning of the sentence was corrected. The punctuation is now properly placed between the phrase describing the primary and the phrase describing the secondary. 2. SRP-UDP format item Revised Review Interface section of Areas of Review to be consistent with SRP-UDP required format which uses a number/paragraph format to distinguish individual reviews performed by other PRBs. 3. Integrated Impact 238. Added a review interface with proposed SRP Section 6.8 related to review of PWR depressurization systems. Overpressure protection may be a subsystem or function of the depressurization system. 4. PI # 15465, Editorial SRP Section 5.2.2 evaluates the over-pressure protection systems that provide protection of the reactor coolant pressure boundary from failure resulting from over-pressure events.
