2.0 Surveillance Testing And Calibration Program 2.1 Scope / Criteria Administrative controls were reviewed to evaluate the licensee's program for implementing requirements associated with surveillance .

testing and calibration activities. Also reviewed was the usage and l control of measuring and testing equipment utilized during the per-formance of various surveillance / calibration activities. The objec-l tives were to assure that the licensee programs in place were

! consistent with the Technical Specifications, Regulatory Guide 1.33, 1 ANSI N18.7, Appendix B of 10 CFR 50 and applicable site administra- '

tive procedure Administrative Control Procedure (ACP)-QA-9.02 delineates how the conduct of the surveillance / calibration program is accomplishe Specific surveillance procedures are utilized during the performance of surveillance / calibration testing. Attachment A lists those ACPs and surveillance procedures that were reviewed during the conduct of this inspectio .2 Review / Implementation A review of administrative procedures, surveillance and calibration procedures, the master surveillance schedule, several departmental

! surveillance schedules and Unit-1 I&C Forms Index was conducted to verify the following.

The technical content of surveillance testing procedures complied with technical specification requirement *

Calibrations were performed to the required accurac *

Measuring and test equipment used during the performance of calibrations were traceabl The documents and procedures listed in Attachment A were reviewed to verify the above attributes. Discussions were held with I&C manage-ment personnel to review the automated Preventive Maintenance Management System (PMMS) program used for scheduling all surveillance and calibrations via automated work orders. In addition, the inspectors reviewed the status of all required l refueling outage surveillance as indicated on the master surveillance index and verified that all required surveillance were either completed or in the process of being completed. The program used for identify!ng and controlling "high risk" surveillance was also reviewed. It was verified that high risk surveillance were

. identified as such by the PMMS on the automated work orders printed for those surveillanc These work orders required written acknowledgements by the Operations Superviso A review of the program used for calibrating technical specifica-tions-related instrumentation was made. This included identifying instrumentation needed to satisfy Technical Specifications and then

'

verifying that the instruments were identified and calibrated under

,

the licensee's calibration program. It was verified through PMMS

!

that these instruments had been calibrated at the frequency specified by the licensee and that procedures or data sheets had been develoned l for each instrument. Most M&TE are calibrated annually.

l During the review of Surveillance Procedure (SP)-412K, LPCI/Contain- i ment Cooling System Logic Test, the inspector discovered that the '

p ocedure did not restore the LPCI pumps suction valves from the j torus to the open position, However, it was verified that the Opera- l tions department would perform a valve lineup of the LPCI system i prior to declaring the system OPERABLE following the surveillance test. A review of the operations valve ' lineup sheet showed that the subject suction valves were identified and their position correctly j l

indicated. The licensee made a procedural change to correct the l above procedure prior to completion of this inspection.

!

l 2.3 Test Witnessing

]

The inspectors also observed the performance of three Technical Specification surveillance / calibration tests performed by licensee personnel during the course of the inspection. The three surveil- ,

lances witnessed included: (1) pump operability tests for the )

l electric fire pump and the Standby Liquid Control pumps, and (2) the l calibration and functional tests of the Average Power Range Monitors '

(APRM). NRC observation of these surveillance was to verify the following was accomplishe I i

i 2.4 Findings q

.

During the conduct of the electric-fire pump surveillance test, thel

inspector questioned the operators as to the station's policy regarding the usage of' lead seals. The inspector had~ noticed that' i l both.a pressure switch isolation valve and a gauge drain.line-I isolation valve had been operated during the test even though lead- ,

seals were . attached to the valve ' handles. Further discussions with  !

other licensee personnel indicated that the lead' seals' intended -  !)

purpose was to prevent inadvertent operation of the-valves. . The valves had been. lead sealed per an American Nuclear Inspector (ANI) 'jl inspection conducted ~in 1985, since shutting the. pressure switch isolation valve would' prevent an automatic start of the electric fire pum .It was evident, however, tha.t the lead. seals affixed ~to the isolation - j and. drain valves, as observed, would'not have prevented. inadvertent- i operation of these valves. It was also' determined that a station 1 policy in regard to the purpose,and usage of lead seals did not exist. The-inspector also noted that lead seals had been affixed in' l a similar manner on the diesel fire pump syste l

!

The inspector determined that this_ problem did not present a 1 significant safety concern since' both pumps were housed in'a locked {

building and were routinely checked by operations personnel, however, ,

there was still a need for further clarification as to the usage of-  !

lead seals.- The Operations Supervisor agreed with the inspector's concern and stated that action would be taken to resolve the ,

situatio Prior to exit meeting on July 24, 1987, the Operations Supervisor presented to the inspector'the following actions that would'b ,

take l l

l

Lead seals would be removed from the valves in question. .The

'

ANI inspector concurred with this action'. ~

All reference to lead seals for these valves would be removed from applicable procedure (

An Operations Instruction would be written delineating the 'i station's policy in regard to usage and intent of. lead seal The inspector stated that these actions adequately addressed his  !

concern _____L_-____-____-______-_-___________-________ - _ - _ _ - _ _ . _ - . . - - - .

! and Test Equipmen l 3.2 Review / Implementation '

The inspector reviewed the administrative program for M&TE, ]

ACP-QA-9.04, against the standards / requirements identified above and q verified the program met all regulatory requirements. .In addition,  !

the inspector reviewed implementation of the program by the I&C-department, the maintenance department and the calibration la ]

The inspector verified that I&C had 1) a. department list of M&TE; 2) 5 an automated program (PMMS). for issuing work orders each week' for ' 4 M&TE requiring calibration; 3) controls on logging out and of M&TE;  ;

4) had tagged each piece of equipment which-identified the- .l calibration due date and the calibration completion date; and 5) 3 developed positive access controls over the area where M&TE was-  !

stored. The maintenance. department was found to have' established j similar controls over their M&TE except that the PMMS did not j identify work orders specific to a piece of equipmen Instead PMMS.- i produces a weekly generic work order which requires maintenance to  !

check each piece of equipment on their M&TE equipment' list against the calibration due date. It was noted that the maintenance depart-

ment calibrated most of their own equipment and that a small backlog l l of M&TE awaiting calibration existed at the time of inspection,

'

However, sufficient spare calibrated equipment was available so that ]

the maintenance program was not impacte j i

The onsite calibration laboratory either calibrates all the M&TE the '

receive or send it out to approved vendors for calibratio It was i verified that M&TE was calibrated against NBS standards or against ]

calibrated equipment which was.at least four times as sensitive'as the M&TE being calibrated. It was also verified that adequate ];

administrative controls existed f.or all M&TE undergoing calibratio ;
