Van Brunt, Executive Vice President Haynes, Vice President - Nuclear Production Ide, Director, Corporate gA/gC Zerinque, Technical Support Manager Papworth, Operations Engineering Manager Shriver, Compliance Manager Kirby, Unit 3 Project Manager 2.'ana ement Discussion A management meeting was held on October 14, 1987, at the NRC Region V
office in Malnut Creek, California.
A summary of each area discussed is provided below.
3.
Annunciator Goals During a meeting held between NRC Region V and ANPP on September 24, 1987, Region V suggested that goals be established with regard to the ANPP Bogus Annunciator Reduction Program and that a schedule be determined to meet those goals.
Mr. Zerinque opened the discussion -by providing a summary of the ANPP short-term goals and schedule.
For Units 2 and 3, the short-term goal is to reduce the number of inappropriately lighted annunciators to 25.
The goal for Unit 1 is 30, due to Unit 1 having an additional number of annunciators which serve systems common to all three units.
The schedule to reach the goal is as follows:
Unit 1 within 90 days of the completion of the current outage; Unit 2 at the completion of the first refueling outage; Unit 3 within 120 days of commercial operation.
Mr. Zerinque then described long-term initiatives in this area, which are intended to improve upon the short-term goals.
An Annunciator Evaluation Program will commence in December, 1987, the purpose of which is to evaluate the appropriateness of modifying or eliminating a number of the existing annunciators.
The onsite engineering group is responsible for this program and will solicit input from operations personnel in conducting the evaluation.
The licensee estimated that the evaluation will be completed by April, 1988.
The licensee also stated that a design reliability analysis will be performed for hardware associated with the annunciator system.
The purpose of the study is to identify recurring hardware failures and system weaknesse J II
The licensee stated that one reason a large number of inappropriately lighted-annunciators exists is the relatively high failure rate of components in annunciator loops.
The reliability schedule is the responsibility of ANPP corporate engineering.
A November, 1988 completion date has been scheduled.
The goals for inappropriately lighted annunciators will be reassessed based on the results of the two programs in December 1988.
Mr. Zerinque noted that approximately 15 annunciators are intended by design to be lighted during normal power operations and, Wherefore, w
"black board" is not presently an ANPP goal.
Mr. Martin questioned the design goals of the original annunciator system and recommended that ANPP clearly think through what is the most desirable normal status for the system.
Mr. Martin also questioned whether ANPP considered their efforts in this area to be worthwhile.
Mr. Van Brunt and Mr. Haynes both stated that ANPP considers improvements in the Palo Verde annunciator system to be important and well worth the project's attention.
Mr. Martin requested that a written description of the ANPP commitments in this area be submitted to Region V.
Mr. Van Brunt agreed to Mr. Martin's request.
4.
Maintenance Backlo During the September 24 NRC/ANPP meeting, the status of the maintenance backlog and the ANPP system for trending the backlog had been questioned.
Mr. Zerinque opened the discussion by describing ANPP efforts to more clearly focus the size of the backlog.
For trending purposes, ANPP has now defined a maintenance item to be backlogged. if<he wtem.is".over-24 hours old for priority 1; over 30 days old for priority 2; and over 120 days old for priority 3.
ANPP has also reassessed ihe assignment of priorities to existing items and eliminated duplicate items <rom<heir system.
The licensee stated that as a result of this effort,.the total number of items identified as backlogged has significant1y decreased and is therefore more easily followed.
For example, in the, area of corrective maintenance at Unit 3, as of October 9, 1987, there were no backlogged priority 1 items, 40 safety-related prioriiy,2 items, and 27 nonsafety-related priority 2 items.
Mr. Zerinque commented that all but, 16 of these items will be worked by initial criticality.
Mr. Ide stated that 45 priority 2 corrective maintenance items exist at Unit 2.
Mr. Martin questioned whether a continuing periodic review of maintenance trends will be performed.
Mr. Zerinque stated that a management review of backlogged items would be conducted every two to four weeks and that a monthly status summary would be provided to Mr. Van Brunt.
Mr. Martin requested that the maintenance area be a continuing meeting agenda item in the future and that the Unit 1 backlog status specifically be discussed:at
%he next Region V/ANPP meeting.
Mr. Martin also questioned whether the ANPP method of tracking the backlog would be formalized in writing and Mr. Van Brunt responded that it would.
5.
~Trainin Mr. Kirby described the actions taken by ANPP to reassess the training area.
In this regard, ANPP had requested the Institute for Nuclear Power Operations (INPO) and the Southern California Edison (SCE)
Company to
evaluate the Palo Verde training program, with emphasis on licensed operator training.
Mr. Kirby reported that INPO and SCE had identified several aspects of the training program where improvements were recommended.
These aspects included the requalification program; the utilization and,,performance of the simulator; the interaction between the-training department and other ANPP organizations; and the guidelines provided to operators regarding shift conduct and division of responsibility.'r.
Kirby then outlined actions scheduled or already implemented Co improve the above areas.
Mr. Van Brunt stated that the assessments had also concluded that the management in the training area has been acceptable; however, the participation of'management personnel, not directly responsible for
%raining, could be increased in the training area.
Mr. Martin reiterated his concern Chat several recent problems in this area indicate that training management has been weak.
Mr. Martin commented that Region V
will continue to make prompt note of any developments in the training area.
6. 'ire Doom Hr. ?de opened'the discussion by describing the background behind the identification of fire door problems at Palo Verde.
A number of inspections of fire doors has been conducted by the licensee.
Two
"categories of 'problems were found.
The first problem concerns modification or repair of doors without proper documentation and the
,~second~roblem..concerns doors which were installed with excessive gaps
.-between the door.and the floor or frame.
Mr. Martin questioned how the doors came to he. modified or repaired without proper documentation.
Mr.
Zde replied that during plant construction, the facility architect-engineer had not maintained sufficient control over the subcontractor responsible for fire door installation.
Mr. Ide stated Chat all discrepancies were expected to be repaired by June, 1988, and that in the interim, compensatory fire watches had been posted in compliance with Technical Specification requirements..
Mr. Martin requested that ANPP provide a table to Region V, which clearly describes the number of fire doors associated with each problem.
Mr. Martin also stated that'egion V would review the significance of maintaining fire
,watches for an extended period of time.
7.
