' Surveillance Requirement 4.5.2.C.2 requires that the visual inspection of the containment be performed at least once daily if the containmant has been entered that day and when the final containment entry is made.. This will reduce the number of unnecessary inspections and also reduce personne'l exposure.

.' ECCS ensures that a sufficient supply of borated water is available for injec-tion by the ECCS in the event of a LOCA. The limits on RWST minimum volume and boron concentration ensure that: (1) sufficient water is available within l containment to permit recirculation cooling flow to the core, and (2) the  ;

reactor will remain subcritical in the cold condition following a large break

, (LB) LOCA, assuming mixing of the RWST, RCS, ECCS water, and other sources of water that may eventually reside in the sump, with all control rods assumed to be out. These assumptions are consistent with the LOCA analyses.

t The contajned water volume limit includes an allowance for water not usable becaus'e of tank discharge line location or other physical characteristics.

The limits on contained water volume and boron concentration of the RWST also ensure a pH value of between 7.0 and 7.5 for the solution recirculated within containment after a LOCA. This pH band minimizes the effect of chloride

, and caustic stress corrosion on mechanical systems ard components.
