Licensee Action on Previous Inspection Findings Infraction 78-08-02:
Inspector reviewed licensee action on item 78-08-0 This item is considered close Additionally the inspector reviewed Revision 3 to PT-25.1 "Pressurizer Safety Valve Testing - Refueling Interval" and verified that changes discussed in Inspection Report 78-08 have been accom plishe.
Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve noncompliance or deviation New unresolved items identified during this inspection are discussed in paragraph.
Calibration The inspector conducted a review of the calibrations worked under the following Trouble Tickets (TT) for 1979:
-2 TT E-025 Align Power Range TT IC-007 Calibrate CVCS Flow Indicators FI-1 122, 124, 127, 130 TT IC-085 Calibrate Pressurizer Vapor Space RTD TT IC-053 Calibrate Accumulator Pressure Transmitters TT IC-099 Calibrate Containment Pressure Instrument TT IOP-671 Calibrate "B" CVCS Pump Pressure Gages TT IC-066 Calibrate BIT Header Pressure TT IC-070 Calibrate RC Pump Seal Water Return Temperature TT IC-069 Calibrate RHR Flow TT IC-073 Calibrate Spray Addition Tank Level TT IC-077 Calibrate Pressure Relief Tank (PRT) Level TT IC-078 Calibrate PRT Temperature TT IC-144 Calibrate Accumulator Pressure Transmitter TT OP-494 Temperature Indicator 432C Reads Low TT IC-094 Calibrate RWST Level The inspector also reviewed the calibration records for measuring and test equipment:
-
TT OP-46 (1978) Calibrate General Radio Strobotac # 30562
-
TT IC-47 (1977) Calibrate Tracerlab AX30 Meter # 5009-504993
-
Mansfield/Green Deadweight Testers # 4031 and 4177
-
Digitec Digital Voltmeter # 9480-9674 The calibrations above were reviewed to verify:
-
Reviews and approvals were being conducted, and data was recorded and evaluate Test instruments were listed and identified in test result Adherence to Technical Specifications required and limiting condi tions for operation Technical contents were correct and verification of return of equipment to service and removal of test equipment was being don The inspector conducted an inspection of the following areas:
-
Instrument and Controls Shop
-
Instrument Standards Room
-
Instrument Storage These facilities were inspected to verify:
-
That standard test instruments were labeled and included in the calibration progra Instruments were being calibrated on schedule and labeled with cali bration statu Storage facilities were proper for protecting the equipmen Certification and calibration records were available and being maintained for test equipmen The inspector used one or more of the following acceptance criteria for evaluating the above items in the calibration program:
-
Maintenance Instruction N, Procedure No. 22 - General Calibra tion Procedure (M16/22)
-
Maintenance Instruction MI-9 -
Control of Measuring Devices and Test Equipment
-
Procedure QAP-6 - Calibration of Special Tools and Equipment

Technical Specifications Within the areas inspected, one apparent item of noncompliance was identifie As required by 10 CFR 50, Appendix B, Criterion V, ANSI N18.7 (1972) and implementing documents Volume II and MI 6/22 safety related instruments are required to be calibrated to within certain accuracie During the review of T#IC-053-Calibrate Accumulator Pressure Transmitters dated 3/17/79, the inspector noted that the High Alarm actuation point for Box # PC-929 on sheet 789 was out of the acceptable range given in MI 6/2 This calibration had received two independent reviews (Supervisor and QA)
and was filed in the vault. Neither of the reviews had identified the out of specification alarm actuation and no apparent corrective action had been take This is designated as an item of noncompliance (261-79-10-01). Maintenance The inspector conducted a review of maintenance documentation as follows:
-4 Trouble Tickets (TT) for 1978 TT 2056 "B" CVCS Pump TT 2108 V2-14A Body to Bonnet (B/B) Leak TT 2308 Containment Spray Pump Pressure Gages TT 2337 Safeguards Train "A" TT 2377 Safeguards Train "B" Test Switch TT 2507 Adjust NIS TT 2512 V2-14A B/B Leak TT 2523 TR410A Indicates High - "A" Cold Leg TT 3009 LT461, 462 Pressurizer Level TT 3057 Power Operated Relief Valve "C" TT 3528 Engine Driven Fire Pump - Propane Leak TT 3555 LT461 Indicates High TT OP-167 R-16 Indicates High (RMS Drawer)
Trouble Tickets (TT) for 1979 TT OP-589 Boron Injection Tank Heaters TT OP-722 Motor Driven Fire Pump TT E-008 QA Vault Fire Protection Modification TT E-013B 4"-SI-110 Needs Support TT MM-028 GE20K Chem Pump Stators The inspector also reviewed the training and qualification records of five maintenance mechanics,'technicians and foreme The inspector used one or more of the following acceptance criteria for inspecting the above items:
-
ANSI N18.7 (1972)
-
ANSI N45.2.9 (1971)
-
Technical Specifications
-

-

-
Inspector Judgement The above documentation was reviewed to verify:
-
Administrative approval was obtained prior to initiating work
-
Where required, maintenance was performed using an approved procedure
-5
-
Where required, functional testing was performed prior to return to service
-
Quality Assurance review was performed
-
Maintenance was performed by qualified personnel
-
Where required, a reportable occurance report was submitted in connection with the maintenanc Within the areas inspected, no items of noncompliance or deviations were identifie However within the areas of post maintenance functional testing, administrative approval to perform work and system restoration an item of concern exists. The licensee accomplishes the above through the use of an Operations Work Procedure (OWP). These documents are written in accordance with the Licensee's Standing Order N and normally contain, a description of maintenance required, technical specification required post-maintenance testing, valve/switch/breaker alignments required for maintenance and restoration and any redundant equipment testing prior to and during mainte nanc These documents are not now reviewed by the Plant Nuclear Safety Committee (PNSC),
this is a recent change as they have been PNSC reviewed in the pas NRC headquarters is presently evaluating whether this type of document is a procedure as defined by ANSI N18.7 (1972)
and therefore is required to be PNSC reviewed per technical specification This item will be considered unresolved pending receipt of NRC headquarters evaluation (261/79-10-02). IE Bulletin 78-06A Refer to Inspection Report 50-261/79-11 for discussion of this inspection effor.
Plant Tour The inspector toured the control room, relay rack rooms, auxiliary feed pump room and turbine area lower leve No items of noncompliance or deviations were identified.
