ENCLOSURE TO NYN-89061 NUREG-0896, Safety Evaluation Report related to the operation of Seabrook Station, Supplement No. 5, required that the following information be L
provided to allow the Staff to complete its review of New Hampshire Yankee's l'
actions on NUREG-0737. Item II.F.2:
Item'fa) notification that the system installation, functional testing, and calibration are complete and test results are available for inspection Responses y
The Inadequate Core Cooling Monitoring (ICCM) system L
installation, functional testing, and calibration has been completed and test results are available for NRC inspection.
Item (b) summary of applicant conclusions based on test results, e.g.,
o performance of the system in accordance with design expectations and within design error tolerances, or o description of deviations from design performance specifications and basis for concluding that the deviations are acceptable
Response
The ICCM system performed in accordance with design requirements. Minor firmware conditions requiring system enhancements were identified during testing. These system enhancements will be implemented prior to exceeding SZ power.
Item (c) description of any deviations of the as-built system from previous design descriptions with any appropriate explanation
Response
The ICCM system was deceribed in SBN-952 dated February 24, 1986.
The ar-built system contains no deviations from that described in SBN-952; however the following two clarifications are provided: i
Item (c) (Continued) o The B train plasma display located at the Shift Technical Advisor's console is powered by a 120 VAC power source. backed by an emergency diesel generator.
It should be noted that NHY does not take credit for the B train plasma display in meeting our commitment for providing Accident Monitoring Instrumentation as required by USNRC RG 1.97.
O The RVLIS page 3 display is used by the operators for obtaining numerical values of the RVLIS parameters on an as-needed basi;.
Item (d) confirmation that the emergency operating procedures (EOPs) used for operator training are complete and conform to the technical content of NRC-approved E0P guidelines (generic or plant specific)
Response
The Emergency Operating Procedures (EOP's) used for operator training are Seabrook Station specific adaptations of the generic Westinghouse Owners Group (WOG) Emergency Response Guidelines which were approved by the NRC in Generic Letter 83-22.
The operator training program utilizes the most.recent revision of these' Emergency Operating Procedures which are complete in all respects and are identical to the procedures used in the plant.
The current revision to these procedures is WOG Rev. lA (Station 1
Revision 6) which has an effective date of December, 1988.
