Bases 1he total steam generator tube leakage llelt of ] GPM for all steamIgenerators ensures that the 3.3.3
~
dosage contribution f rom the tube leakage will be Ilmited to a small fraction of Part 100 limits i
4.3.3 in the event of either a steam generator tube rupture or steam Ilne break. 1he 1 GPM limit is consistent with the assumptions used in the analysis of these accidents.
The 500 gpd leakage j
limit per steam generator ensures that steam generator ensures that steam generator tube integrity 2
15 maintained in the event of a main steam line rupture as under LOCA conditions.
(
j Pressure Isolation Valves (PtVs) are defined for each interface as any two valves in series within the Reactor Coolant System (RCS) pressure boundary,which separate the high pressure RCS from the attached low pressure systems. PIVs fall into two risk categories. The high risk PIVS are those j
whose gross failure could result in an Event V accident as identified in WASH-1400. "Reactor Safety Study". II.he Event V valves at Zion are,1dentified as those valves that isolate the residual heat removal system (RNR) from the RCS. These valves represent a high risk because their i
j failure could lead to en overpressurization of The RHR piping and its subsequent failure.
The failure of the RNR piping represents a high risk. factor in the eventual occurrence of core melt due to the inability to estabilsh recirculation from *he containment sump.
It also represents a i
higher risk because the rupture of the RNR piping results in a LOCA that bypasses the i
containment. The remaining PIVs are of a lower risk because they do not lead to a LOCA that 1
bypasses containment or that ruptures lower pressure piping. Leakage past these valves still constitutes a degradation of the RCS pressure boundary as defined in 10 CFR 50.2.
~
Periodic tests or verifications of the leak tight integrity of all pressure isolation valves are necessary in order to ensure the integrity of the RCS pressure boundary. The Survelliance 4
Requirements for PIVs provides added insurance of valve integrity and thereby reduce the l
probability of an letersystem LOCA.
