a FUEL PERPORMANCE Unit 1 The core average fuel exposure accumulated during October was O MWD /MTU with the total accumulated core average fuel exposure of 0 MWD /MTU.

Unit 2

~

The core average fuel exposure accumulated during October was O MWD /MTU with the total accumulated core average fuel exposure of 8097.51 MWD /MTU.

SPENT FUEL PIT STORAGE CAPABILITIES '

The total storage capability in the spent fuel pit (SFP) is 1,386.

However, there are five cell locations which are incapable of storing spent fuel.

Four locations (A10, All, A24, A25) are unavailable due to a suction strainer conflict, and one location (A16) is unavailable due to an instrumentation conflict. Presently, there is a total of 348 spent fuel bundles stored in the S,PP.

Thus, the remaining storage capacity is 1,033.

SPENT FUEL PIT INVENTORY A complete inventory via cassette tape of all 348 spent fuel bundles was performed on September 17 and 18, 1986. This inventory both resolved a discrepancy report and met a requirement in Plant Instruction TI-l to perform an inventory of fuel at least every twelve months. No discrepancies were observed.

NOTE: An inventory of new fuel in the new fuel storage vault was performed on August 5, 1986.

PORVs AND SAFETY VALVES SUIG4ARY No PORVs or safety valves were challenged in October 1986.

LICENSEE EVENT REPORT (S)

The following licensee event reports (LERs) were reported to the Nuclear Regulatory Commission in October 1986.

LER Description of Event 1-86041 Two inadvertent diesel generator (D/G) starts occurred on September 14, 1986 and September 17, 1986, respectively.

Item 1 -

While replacing "KAZ" actuators on vital board IV, power was inadvertently removed from the logic relay panel for shutdown board 2B-B, causing a D/G start (1A-A, 2A-A, IB-B started). The occurrence was caused due to a procedure inadequacy resulting from a lack of instructions on marking up drawings in the main control room. After a modification on board IV, drawings were updated on unit 2 only; not both units. All electrical prints related to this event have been updated for both units.

l LER DescriDtion of Event i

Item 1 -

.- During this event, when 1B-B diesel generator was returned to (continued) normal, it tripped on high jacket water temperature. Essential raw cooling water is automatically supplied at a given setpoint, however, the supply was isolated to IB-B.

Operations personnel failed to recognize.the flow path of raw water to this diesel.

Personnel involved were cautioned to ensure system lineup is

~

correct.

Item 2 -

While attempting to replace "KAZ" fuses with " MIS" fuses, an inadvertent D/G start occurred when a jumper that was used to mala min guer to che. shutdown board came loose and blew the fuse to the adjacent circuit. The fuse was replaced and the i

D/Gs returned to service. Personnel were cautioned about working in confined areas.

i 1-86042 The following items pertain to Surveillance Requirement 4.0.5,Section XI Requirements which were determined on September 8, 1986.

j Item 1 -

It was determined that SI-129, "Beergency Core Cooling Safet/

Injection Pump Operability," does not require the verification of closing of the discharge check valve during testing if the RCS is less than 1700 psig as required by Surveillance Requirement (SR) 4.0.5.

This test ensures that if one safety injection pump fails to start, flow will not be lost through the failed pump. However, this is performed when the RCS pressure is greater that 1700 psig. This procedural error was caused by interpretation of ASME XI Requirements and complexity of SR 4.0.5.

The instruction will be revised to include this activity before startup.

Item 2 It was determined that thermocouples and resistance temperature detectors have not been calibrated as required by TS Definition 1.3 for channel calibration. Due to the fact that these items cannot be adjusted, a calibration was previously assumed to be nonapplicable. The sensor is required to be calibrated with the rest of the channel, but it was not. Such sensors are used in systems such as the RCS, residual heat removal system, and monitoring of the pressurizer relief tank. A calibration procedure will be implemented to verify these sensors.

i 1-86043 A review of SI-156, " Containment Integrated Leak Rate Test,"

determined that this SI was inadequate for leak testing of the i

containnent isolation valves FSV-30-134, -135 (Annulus Differential Pressure Isolation Valves) and valve 529 (Demineralized Water System) as required for SR 4.6.12.

Venting is required for proper leak testing to ensure the backside will l

be at atmospheric condition. All valves have been properly retested with required venting and zero (0) leakage was determined. SI-156 will be revised to reflect the correct l

Venting procedure. The discovery of this event was September 10, 1986.

4 1-86044 It was determined on September 25, 1986, that SI-137.3,

" Measurement of The Controlled Leakage To The Reactor Coolant Pump Seals," did not adequately ensure that the seal injection flow rate during a loss of coolant was less than or equal to that which was assumed in the accident analysis as required for SR 4.4.6.2.1.C.

This SR is to ensure that a flow of less than or equal to forty (40) gallons per minute is measured while the RCS is at 2235 1 20 psig and a pressure drop of greater than or equal to 100 pounds per square inch exists across the seal injection lines. SI-137.3 will be revised before startup to reflect SR 4.4.6.2.1.C.

1-86045 An emergency D/G sta'rt occurred at 0920 CDT, October 2, 1986, while performing modifications on a limitorque operator for ERCW normal supply valve (1-FCV-67-66) to lA-A diesel generator. As maintenance was being performed, a deenergized wire 7

inadvertently touched an energized part of the circuit. A review indicated a blown fuse contributed to the start. The Bussman " MIS-5" fuse is being investigated to determine its quality and reliability before startup of either unit. The D/Gs were returned to normal position.

INSTRUMENT MAINTENANCE MoWTHLY REPORT FOR OCTOBER 1986 COMMON 1

1.

Work Request (WR) B202885 was initiated by the Operations Section to.

investigate a higher than normal indication on the Auxiliary Building.

Exhaust Stack Flow Monitor (Loop 0-F-30-174).

Flow transmitter

.0-FT-30-5174A was found out of desired tolerance and recalibrated.

~

e PRO 1-86-275 was initiated to evaluate the condition.

2.

WR 12107 was approved to replace the condensate Demineralizer Regenerant Effluent Composite Sample Flow Monitor 0-FI-14-466.

This replacement is being performed in accordance with ECN L6737 (D-FCR-4541RI) and is part of corrective action for PkO 1-86-104.

3.

Received on site the special calibration test equipment for the Static-O-Ring (SOR) differential pressure switches used in the UHI system. These calibrator units were purchased from SOR to calibrate the switches, compensating for the system pressure static shift. This static pressure shift problem was identified to SQN in NRC-IE Notice 86-02 and procurement of the special calibrator units is the corrective action being taken_in response to this NRC notice. Both of the calibrator units purchased were defective from the factory (i.e., they experienced internal pressure leakage) and steps are being taken to remedy this problem. The UHI switches will be recalibrated using these special calibration units. This is required for startup.

4.

Discovered that the Measuring and Test Equipment (M&TE) used in SI-125 (Calibration of Seismic Monitors) had never been included in a calibration certification program. PRO l-86-295 was initiated to 4

evaluate this condition. Steps have now been initiated to include the calibration of the M&TE on a regular schedule at the TVA Central Lab.

t 5.

Completed revisions to SI-98.1 (Functional Test of the Auto Stop Oil for Turbine Trips), SI-695 (Calibration Procedure for Auxiliary Building Steam Line Isolation Temperature Switches), and SI-706 (Vital i

Instrumentation Sense Line Insulation Inspection Procedure), which were all required for unit 2 startup. The SI-l checklist was completed and submitted on these procedures.

6.

'Responsed to Operating Experience Review WBN-NCR-6750s concerning l

problems with the Isokinetic Sampling Systems at Watts Bar Nuclear Plant supplied by Air Monitor Corporation. The two problems identified on the experience review were in regard to:

(1) lack of QA requirements being specified on the contract to meet the requirements of Reg. Guide 1.97 and (2) failure of vendor to provide an Operation and Maintenance Manual showing the latest configuration of the instrumentation, and failure to l

provide equipment upgrades to maintain system operation. Our response noted that the applicability of item (1) to SQN is indeterminate until the SQN Reg. Guide 1.97 review is complete. For item (2) our response indicated that similar problems do exist at SQN and recommendations were made for SQN Division of Nuclear Engineering (DNE) to coordinate with Air Monitor Corporation in determining what system upgrades are needed and to obtain an updated vendor manual.

O-INSTRUMENT MAINTENANCE MONTHLY REPORT POR OCTOBER 1986 COPMON (continued) 7.

Responded to five PROS on various compliance instruments on both units 1 and 2.

The PROS were initially categorized as Not Reportable by the PORS engineer. The PRO numbers are 2-86-096, 1-86-264, 1-86-270, 1-86-271, 2-86-105.

8.

Received final copy of Westinghouse setpoint methodology report (WCAP 11239R2). This report documents adequacy of reactor trip and engineered safety features-instrumentation setpoints. The report will be reviewed by a special subconnittee and submitted to PORC for official issuance.

UNIT 2 1.

A unit 2 containment vent isolation occurred because of spurious high radiation signal spikes from radiation monitor 2-RM-90-106B.

PRO 2-86-098 was initiated to evalute the condition. Investigation revealed that the probable cause for the erroneous high radiation spikes was electrical nois,e from welding machines being used inside containment.

2.

In continuation from unit 2, item 2 in the September 1986 Monthly Report, the WRs for rotating four steam generator level transmitters (2-LT-3-43, 56, 94, 107) were approved and worked. The transmitters were rotated and recalibrated to satisfy SCR-8620Rl. Quality Information Release (QIR) No. SQN86173 was submitted to close this open item in EQ Binder SQNEQ-XMTR-001.

3.

WR B202076 was initiated by the Operations Section to investigate erroneous readings on unit 2 shield building stack flow monitor (loop 2-F-30-242).

Flow transmitter 2-FT-30-5242A sense lines were purged and transmitter was recalibrated. PRO 2-86-100 was initiated to evalute the condition.
