SUBJECT:
Washington Public Power Supply System (WPPSS)
WPPSS Nuclear Project No.
2 (WNP-2)
SUMMARY
OF MEETING WITH WASHINGTON PUBLIC POWER SUPPLY SYSTEM ON OCTOBER 29, 1991$
TO DISCUSS STATUS OF SIMULATOR FACILITY CERTIFICATION On October 29, 1991, members of the NRC staff met with representatives of the Washington Public Power Supply System (the licensee or WPPSS) to discuss the status of the WPPSS Nuclear Project Number 2 (WNP-2) simulator.
The licensee began the meeting by presenting background information regarding its previous request for exemption from the simulation facility certification requirements of 10 CFR 55.45.
The NRC crarited the request for exemption and extended the deadline for certificatiorI of tlIe llNP-2 plant referenced simulator to June 30, 1992.
The request for extension was based on the projected delivery date for the plant referenced simulator by Westinghouse of December 31, 1991.
The licensee stated that it had been informed by the vendor that delivery of the simulator would be further delayed.
The delay is due to difficulties encountered during the development of the boiler model.
The licensee stated that woI'I;ablIe boiler models had been developed by both Singer and Exitech; however, it had not pursued obtaining other models as yet.
The licensee also stated that simulator software architecture had not been proven to simulate plant response on a real time basis.
The licensee stated that Westinghouse was also working on the simulator for Oyster Creek and that GPU Nuclear had also been notified that simulator delivery dates were uncertain.
Although a definitive delivery date for the WNP-2 simulator had not been identified, WPPSS stated that delivery was projected around December 1992.
The licensee also noted that the initial operator licensing exams currently scheduled for August 1992, are required to be conducted on the new plant referenced simulator.
In light of the revised delivery date, the licensee stated that revisions to the operator licensing exam requirements or schedule might be necessary.
The NRC acknowledged the licensee's presentation, suggested that the licensee continue to follow the progress of the simulator vendor closely and requested that it keep the NRC informed of any changes to the simulator schedule.

ONGOING CONCERNS
~
Boiler Model - Supply System still captive to GPU Nuclear's model development.
Progress has been unsteady and until recently, not critical path.
Other Models - uncertain about main energy loop models not yet reviewed.
~
Quality - balance between our determination to have the highest fidelity and to deliver our simulator.
9J'estinghouse's haste may indicate future problems.
Schedule -The vendor is over a year behind the original delivery schedule. The critica1 gath has been model development and documentation.
The test program is urdRely, to be complete by our deferred date for certification.

SUPPLY SYSTEM ACTIONS To stimulate Westinghouse to perform and to expedite the program me have:
- l. Limited the scope of prelinnnary testing to verify the simulator's readiness, the Supply System's test program shrill validate the simulator's performance.
- 2. Demanded that a parallel path to install an alternative boiler model be initiated; procure a completed model from another vendor.
- 3. ivIKintain top management oversight and pressure on westinghouse executI:ves to attend to their simulator development problems.
- 4. Invoked liquidated damages provided by the contract for late delivery.

CERTIPICATIONPROGRAM The simulator procurement Technical Specification provides basis to certify physical and dynamic fidelitywithout exceptions.
Test program designed meet CFR requirements and ANSI/ANS 3.5, Regulatory Guide 1.149, and NUREG-1258 guidance.
The Supply System maintains a configuration management system which tracks plant changes for updates on delivery of the simulator.
A certification plan has been established which detaQs each functional area and section of our planned submittal.
Abstracts of tests and assessment of available data and analysis, plant procedures, LER's, FSAR's, etc. have been made to establish the test program.
Test results are, and remain the missing element for our submittal.
WNP-2 SIMULATOR October 29, 1991
CURRENT SIMULATORPERFORMANCE In April 1990, outlined the upgrades made to the current simulator to support its
- remairmg useful life.
Upgrades included new or significantly improved boiler/recirculation, condensate
~
and feedwater and steam line models, enhancements to the instructor system and installation of a stimulated plant process computer and graphics display system.
Since the upgrade project we have continued to address discrepancies identified by the training and examination programs and enhanced the simulator s transient response to support training and examination for emergency operating conditions.
The simulator has continued to be used successfully to support traixung and operator license examinations.
Listed below are significant NRC examinations that have been conducted on the simulator in 1991:
- March Annual R/Q Examination and Operational Evaluation
- June Operational Evaluation and Re-examination
- August Annual R/Q Examination September Annual R/Q Examination and Operational Evaluation WNP-2 SIMULATOR October 29, 1991
