Tiernan (BGE) to NRC Document Control Desk, dated August 9,1988, Regulatory Guide 1.97 Review Update In Reference (a), the NRC concluded that Category 2 shutdown cooling heat exchanger inlet or outlet temperature is an acceptable alternative to containment sump water temperature. In Reference (b), we stated that since Residual Heat Removal Heat Exchanger Outlet Temperature is already considered as a Category 2 instrument, it would be utilized to meet the requirement for containment sump water temperature. Plant modifications to upgrade the Residual Heat Removal Heat Exchanger outlet temperature element to safety-related and environmentally-qualified resistance temperature detectors were completed in spring 1989 under Facility Change Request 83-24. All actions for this item are complete for Units 1 and 2.
