-2-An apparent weakness was identified, however, in the licensee's calibration program for I&C devices not addressed in the TS. The apparent weakness involves a lack of procedural controls which resulted in a large number of installed I&C device calibration deferrals. This issue has been identified as an.aresolved item.
Inspection Conducted January 9-13 and 23-27, 1989 (Report 50-499/89-01)
Areas Inspected:
No inspection of Unit 2 was conducted.
Results: Not applicable.

Calibration of Plant Instrumentation (56700)
This inspection was to accertain whether the licensee had developed and
.
implemented a program for the calibration and testing of plant installed I
I&C devices. This includes the I&C devices specified in the Technical'
Specification (TS) and-I&C devices that are used for the operation and testing.
of equipment but not specifically addressed in the TS as requ' iring

2.1 Calibrations Specified by TS Calibrations required by TS are controlled as part of the STP Plant Surveillance (PS) Program. The inspection determined.that procedures for calibration of plant. installed I&C devices, specified by.TS, are being implemented in accordance with the calibration program administrative-i
'
controls, as prescribed by the STP FS/.R. Sections 7.0 and 17.2, and related commitments to Regulatory Guides and Standards. The TS surveillance program data base is well established and re flects.the status.of. all planned 'in-plant
'
surveillance tests and inspections. This schedule.is outlined in STP Operations QA Plan - Instrumentation and Calibration Control (QAP),
.
l-Section 12, phragraph 6.1, and STP Plant Procedures Manual.(PPM)
l OPG P03-ZM-0016, Revision 1.
Technical Specification surveillance and
'
calibration requirements'are further controlled by Procedure OPG P03-ZE-0004, Revision 2, and together with the QAP include requirements-that verify
..
completion of, surveillance tests.and inspections required by the TS.
)
The NRC inspector verified that installed I&C device channel calibrations (CCs), analog channel operational tests (ACOTs), trip l
actuating device operational tests (TAD 0Ts), actuation logic tests (ALTs),
master / slave relay tests (MRTs/SRTs), and response time tests (RTTs),
specified by the TS were performed.at the required frequencies. The NRC inspector used the TS Surveillance Program Data Base for STP-1 dated January 11, 1989.
.
.
.
l The NRC inspector examined completed test and calibration procedures (documentation packages) for surveillance performed during the last 18 months. This review verifiedi (1) test documentation was complete; (2) approved procedures were utilized; (3) acceptance criteria were met; (4) performance was in accordance with the procedures; and (5) completed procedures contained "as found" conditions.
The specific documentation packages examined by the NRC' inspector are listed below:

Train R Reactor Trip Breaker, TAD 0T The NRC inspector made the following observations with regards to the licensee's PS program:
2.1.1 RTT Procedures Data packages were prepared by HL&P, using preoperational test data prior to station startup of STP-1, in lieu of RTT requirements by TS.
Many RTT procedures for frequencies of 18-months and greater, have l
not yet been issued.
At the tine of this inspection, 207 out of I

approximately 1000 RTT procedures still remain in draft form.
These procedures will be issued at STP-1 prior to the first TS required RTT period.
2.1.2 CC Procedures Preoperational test data packages for STP-1 were used in lieu of. CC procedures to meet initial CC surveillance requirements. The CC surveillance were short-period calibrations which have since been
!
accomplished using newly issued CC procedures. The NRC inspector estimated that 10 percent of STP-1 CC surveillance were performed, taking credit for test data packages.
2.1.3 ACOT, TADOT, ALT, MRT, and SRT Procedures All initial and' subsequent ACOTs, TAD 0Ts, ALTs, MRTs, and SRTs-for STP-1 are being. accomplished using issued surveillance procedures.
No' violations or deviations were identified.
,
2.2 Calibrations Not Specified by TS The programmatic controls for the calibration of installed I&C devices used at STP for safety-related/ quality-related applications, associated:
but not addressed in the TS, are part of the STP preventive maintenance (PM)
<
,
l Program. These instruments are used during surveillance testing and -
operation of safety-related equipment and are referred to in the STP plant routine operating procedures.
The schedule of calibration and verification for these insta11ed'I&C devices is outlined in the STP QAP, Section 12 and
,
l Procedure No. OPGP03-ZM-0002, Revision 16. "PM Program."
HL&P has accomplished an engineering review of some 7000 safety-related/
quality-related instrument devices to determine their requirements with regards to PM calibration activities.
HL&P has established an approved and active PM list of approximately 1500 instrument devices based on the following criteria:
HL&P reviewed the Architect Engineer's (Bechtel's) instrument index
l and included safety-related instrument classification groups on the approved PM list.
HL&P reviewed all STP routine operating and surveillance procedures and included all instruments contained in these procedures on the
'
approved PM list.
HL&P accomplished an engineering review of the STP main control room
and included all these instruments on the approved PM list.

The.NRC inspector reviewed the licensee's implementation of Procedure OPGP03-ZM-0002 to ascertain whether calibration of'the, selected-
~
instrument devices in the.PM program were~being accomplished effectively.
d-The NRC inspector reviewed the licensee's PM Schedule. Data Base,L ated
,
January 25, 1989.' The data base.is used by HL&P to prioritize:the scope and frequency of the required PM calibration activities. - The NRC -
~
.,
inspector. sampled PM data packages listed on the data base-for::
.
'
(1) backlog of past due calibrations; (2) reasons' for deferrals, inactivations,.and cancellations; (3) availability of approved procedures.
for calibration of instrument devices; and.(4) examination of technical
'
content. The sample PM data packages were limited to instrument device calibrations performed by the maintenance. I&C division. - The-followingL is a list of PM procedures reviewed:
