-2-EXECUTIVE SUMMARY Washington Nuclear Project-2 NRC Inspection Report 50-397/97-15 The inspection of the control of surveillance testing was prompted by past performance problems in implementing the program, which resulted in mode changes being made without all required equipment being operable, Maintenance Significant progress has been made in addressing control problems associated with implementing surveillance testing for meeting both Technical Specification and post-maintenance testing requirements.
However, a comprehensive assessment on the effects of those efforts cannot be made at this time since all licensee actions have not been completed (Section M3.1).
~
The self assessment of the readiness for mode change at the end of the 12'"
refueling outage was thorough and objective.
Good recommendations were made (Section M7.1).
-3-Re ort Details Summar of Plant Status The unit was operating in Mode 1. The unit was at 100.percent power for the majority of the week.
Power was reduced during the performance of, and recovery from, a loss of a feedwater pump te'st conducted during the evening of July 23, 1997.

Ins ection Sco e 61725,
The inspector reviewed Procedure 1.5.1, "Surveillance Testing," Revision 22; Procedure 1.5.13, "Scheduled Maintenance System (SMS)," Revision 4; "WNP-2 Refueling Outage 12 Restart Mode Change Readiness Self Assessment Report,"
dated June 30, 1997; and, the problem evaluation requests listed in the attachment, In addition to reviewing those docurr;ents, the inspector interviewed plant personnel with responsibilities for the implementation of the surveillance testing program.
Observations and Findin s The inspector noted that the procedures controlling the implementation of the surveillance testing program were well written. However, the inspector found, as did the licensee's self-assessment team, that there were weaknesses in the program.
The licensee's self-assessment team concluded that the weaknesses in the program were not significant because of the knowledgeable people implementing the program.
Weaknesses in the program identified by the inspector included the ability to close a work document without completing all of the post-maintenance test requirements.
This potential included surveillance tests that were to be credited for both the surveillance and the post-maintenance tests.
The inspector identified two examples where this occurred (Problem Evaluation Requests 297-0615 and 297-0616).
In both examples, the person annotating the status of the task on the data base did not identify that the task was only partially complete.
While a more knowledgeable person would have been aware of the significance of partial completion of the tasks, the software for the PASSPORT program (i.e., the work control process and
4-planning and scheduling computer program) allowed the task to be annotated improperly.
These errors were identified by the licensee and corrected before declaring the equipment operable and before any entry into a mode where the equipment was required to be operable.
Additionally, while the equipment was inoperable until properly tested, the time allowed by the Technical Specifications was not exceeded in either case.
The inspector noted that, while there were some weaknesses in the procedural controls of the surveillance testing program', the licensee's staff had attempted to identify and correct weaknesses in the individual test procedures in response to escalated enforcement for mode change violations identified in NRC Inspection Report 50-397/96-19, and during the development of the improved Technical Specifications.
The inspector also noted that the licensee was changing the software control program from PASSPORT to BASELINE after this inspection was completed.
The inspector found that, while the licensee has had the BASELINE system running in parallel with the PASSF ORT system, close attention was warranted to assure that surveillance testing was not missed and that entry into a prohibited mode would not occur.
The inspector found these examples to be of minimal significance with respect to the escalated enforcement issues because no Technical Specifications were violated.
The inspector also found that the licensee',s programs and procedures for controlling surveillance and post-maintenance testing, in response to the escalated enforcement, were still being implemented.
C.
Conclusions The licensee had made progress in addressing control problems associated with implementing surveillance testing for meeting both Technical Specification and post-maintenance testing requirements.
However, a comprehensive assessment on the effects of those efforts cannot be made at this time since all actions have not been.
completed.
Additional time is warranted to observe the results of the
. implementation of the BASELINE planning and scheduling system.
M7 Quality Assurance in Maintenance Activities M7.1 Mode Chan e Readiness Self Assessment Ins ection Sco e 61725 The inspector reviewed the licensee's self-assessment report for mode change readiness dated June 30, 1997, and interviewed the assessment leader and plant management personnel.
The inspector also reviewed a sampling of required mode change surveillances for the 12'" refueling outag b.
Observations and Findin s The inspector noted that the self-assessment team identified many weaknesses in the process for controlling mode changes.
The self-assessment team identified that the process was "fractured"; however, they considered the use of knowledgeable personnel to supplement the process for the 12'" refueling outage to have been adequate to prevent a mode change error.
The inspector noted that licensee management had requested the self assessment.
The inspector found that licensee management expressed the position that changes were necessary to the surveillance and work control processes to ensure that no similar problems; as experienced during the previous two assessment periods, would occur.
An operations department representative was assigned the task to develop plans by September 1, 1997, to carry out the recommendations presented by the self-assessment team.
The inspector noted that personnel involved with the process, and who would be affected by changes to the process, were not included in the development of the action plan.
When the inspector discussed the lack of involvement of the affected personnel with licensee management, the inspector was told that those people would be included.
c, Conclusions The self assessment was thorough and objective.
Good recommendations were made.
V. Mana ement Meetin s X1 Exit Meeting The inspector presented the inspection results to members of licensee management at the conclusion of the inspection on July 25, 1997.
The licensee personnel acknowledged the findings presented.
The inspector asked the licensee personnel whether any materials examined during the inspection should be considered proprietary.
