Leon Engle, Project ! tanager, Light Water Reactor Br. # 1 THRU: Thomas it. *:ovak, Chief, Reactor Systems Branch', DSS DAVIS-BESSE 1 PCST-ACCIDENT l10NITORING In accordance with your request, we have reviewed the FSAR for informa-tion readouts available to the operator for.'onitoring key parameters.
With the exception of containnent sump level and SWST level, it would appear that a representative sample of conitoring instrt: mentation is pro-vided; however, it is less clear that they are sufficiently qualified for post-accident monitoring.
As you know, the staff presently has no uniforn basis to review the acceptability of such a list. 'Jhile it would acpear that Davis-Besse does not have fully qualified instrurentaticn for post-accident monitoring of any RSS carareters, there is no clear basis for finding
~
their submittal unacceptable.
A Task Force coordinated by the Accident Analysis Branch has been assigned the responsibility of generating further NRC guidance certaining to c.ost-accic'ent instrumentation.
If the result of this generic effort indicates that additional requirenents are warranted, we will identify en Davis-Besse which modifications are necessary to assure that an acceptable level of safety is maintained.
