Collowuo on Previously Identified Items (Units 1 and 2)
- Closed) Unresolved Item 313/8012-07; 368/8012-07
Licensed operator absent from license duties for greater than four months.
The observation training performed by the licensed operator has been documented by a memorandum dated November 5, 1980.
3.
Operational Safety Verification (Units 1 and 2)
The inspectors observed control rocm operations, reviewed applicable logs and conducted discussions with control room operators.
The inspectors verified the operability of selected emergency systems, reviewed tagout-records and verified proper return to service of affected components.
Tours of accessible areas of the units were conducted to observe plant equipment conditions, including potential fire hazards, fluid leaks, and excessive vibrations and to verify that maintenance requests had been initiatea for equipment in need of maintenance.
The inspectors, by observation and direct interview, verified that the physical security plan was being implemented in accordance with the station security plan.
The ir.spectors cbserved plant housekeeping / cleanliness conditions and verified implementation of radiation protection controls.
The inspector walked down the accessible portions of the Unit 2 "A" high pressure safety injection, Unit 2 "A" low pressure safety injection, and Unit 1 motor and turbine-driven emergency feedwater systems to verify opera-bility.
The inspector also witnessed portions of the radioactive waste system controls associated with radwaste shipments and barrelin These reviews and observations were conducted to verify that facility operations were in conformance with the requi* aments established under technical specifications,10 CFR, and adminis *ative procedures.
During a tour of the Unit 1 auxiliary building, the inspector noted that most of the local breaker indication lights on the 4160 KV Emergency Safe-gurads electrical buses (A3 and A4) were not illuminated as designed.
Since the safeguards equipment powered from these electrical buses may have to be operated from their local breakers in an emergency, such as discussed in emergency operating procedure 1202.33, Remote Shutdown, the inspector is concerned that such local operation would be hampered without functioning breaker indication lights.
This item will be included in an existing similar open item for Unit 2 (368/8017-04) pending implementation by the licensee of measures to replace burned out bulbs.
No violations or deviations were identified in this area.
4.
Monthly Surveillance Observation (Units 1 and 2)
The inspector observed the technical specification required surveillance testing on the number 1 Unit 2 Emergency Diesel Generator and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for operation were met, that removal and restoration of the affected components were accomplished, that test results conformed with technical specifications and procedure requirements and were reviewed by personnel other than the individual directing the test, and that any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personnel.
The inspector also witnessed portions of the following test activities:
Quarterly calibration of Unit 1 process radiation monitors (Procedure
.
1304.26)
Monthly test of Unit 1 Decay Heat Removal Pump P34A
.
Annual surveillance on Unit 2 "A" High Pressure Safety Injection pump,
.
2P89A.
(Procedure 2104.39, Supp. I)
.
Recorded test run of the Unit 2 steam-driven emergency feed pump, 2P7A.
While observing the annual surveillance on Unit 2 "A" High Pressure Safety Injection pump (2P89A) the inspector made the following observations:
The pressure gages installed on the suction and discharge lines of
.
the pump had no calibretion stickers.
The licensee reported that the gages were part of a large contingent of gages that were received during the previous month to assist in the recovery effort'from the t
.
.-
--
- -.,
clogging of the service water system by Asian clams and were all calibrated upon their arrival on site.
The inspector's concern is that many of the ne.: pressure gages are being permanently installed in locations that previously utilized removable test gages.
As a result, these gages are being used as process gages and are not under a calibration control system.
This item will remain open pending the inclusion of these new pressure gages into a calibration control system.
(368/8022-01)
The annual surveillance procedure (procedure 2104.39, Supp. I) requires
.
that the High Pressure Safety Injection pump bearing temperatures be measured with a hand-held pyrometer and the values be recorded.
Since a direct bearing temperature cannot be recorded du"ing pump operation using this hand-held instrument, the operator periorming the surveillance is left with a wide choice of locations from which to obtain a tempera-ture reading that would reflect an overheating problem with the pump bearings.
The surveillance procedure, however, provides no guidance as to where to measure the temperature and, therefore, allows for no consistency for trend analysis purposes from one year to the next and makes the utility of an acceptance criteria for the recorded temperature questionable.
This item will remain open pending the implementation of more detailed guidance for obtaining the temperature readings during the annual surveillance tests for the High Pressure Safety Injection pumps.
(368/8022-02)
No violations or deviations were identified in this area.
5.
Monthly Maintenange Observation (Units 1 and 2)
Station maintenanca activities of safety-related systems and components listed below were ibserved/ reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with technical specifications.
The following items were considered during this review:
the limiting conditions for operation were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and we.1 inspected as applicable; functional testing and/or calibrations were pernrmed prior to returning components or systems to service; quality control records were maintained, activities were accomplished by qualified personnel; parts and materials used were properly certified; radiological controls were implemented; and, fire prevention controls were implemented.
l Work requests were reviewed to determine status of outstanding jobs and to assure that priority is assigned to safety related equipment maintenance which may affect system performance.
The following maintenance activities were observed / reviewed:
.
Trouble-shooting and repair of excessive vibration problem on Unit 2
.
"B" High Pressure Safety Injection Pump, 2P898.
(Job Order 1435)
Repair of Unit 2 instrument air header after rupture.
(Job Order 01742)
.
Turbine governor modifications on the Unit 2 steam-driven emergency
.
feed pump, 2P7A.
(Job Order 1305 and Design Change Package 80-0-2174)
Following completion of maintenance on the Unit 2 "B" High Pressure Safety Injection Pump and the Unit 2 instrument air header, the inspector verified that these systems had been returned to service properly.
While observing the overhaul of the "B" High Pressure Safety Injsction Pump motor (2P898) for Unit 2, the inspector noted that post-maintenance equipment restoration was not completed.
Approximately one week after the dpplicable job order (Job Order 1435) was closed out, the inspector dis-covered that the pump motor air screens had not been replaced and were lying on the floor adjacent to the motor.
This finding was relayed to a licensee representative and the problem was corrected on the same day.
Design change package 80-D-2174 modified the governor control mechanism on the steam-driven emergency feed pump (2P7A) for Unit 2 to improve the governor control mechanism's reliability and to provide for additional parameter monitoring locations for t o ting.
The modifications included replacing the existing stainless steel tubing for the electro-hydr.ulic governor control system with new thin walled tubing and installing a signt glass to monitor hydraulic oil level in the EG-R sump.
The inspec-tor noted during his review of this design change that although a seismic analysis was performed on the new stainless steel tubing, no consideration appeared to have been given to the seismic qualification of the added
.
sight glass.
This item will remain unresolved until the seismic qualifi-cation for the EG-R sump sight glass is included in the design change pack-age.
(368/8022-03)
No violations or deviations were identified in this-area.
6.
Precaration for Refuelino (Unit 1)
The inspector reviewed procedure 1503.02, Revision 2, dated July 15, 1980, entitled " Fresh Fuel Inspection and Storage." Also reviewed were the records of the receipt and inspection of Burnable Poison Rod Assemblies on July 17, 1980, and tne records of the receipt and inspection of new fuel assemblies on July 18 and 25, 1980, and August 1, 8 and 15, 1980.
No items of noncompliance or deviations were identified.
This inspection effort, including review of the licensee's procedures for fuel handling, core verification, fuel inspection, fuel sipping, and core internals handling will be continued in the next inspection perio.
-
No violations or deviations were identified in this area.
7.
High Range Noble Gas Effluent Monitor (Units 1 and 2)
This monitor was installed in January 1980, in response to item 2.1.8.b of NUREG-0578.
The licensee's letter of January 18, 1980, to the Commission stated that this "... system will be checked against a remotely installed source monthly, and calibrated every three months." The inspector found that no calibrations have beea performed on this system since the initial calibration when it was placed in service and no monthly checks have been performed.
A licensee representative informed the inspector that an annual calibration is planned for this instrument and that a letter revising the calibration commitment would be sent to the Commission.
The licensee's failure to calibrate this instrument quarterly and to source check it monthly is an apparent deviation from one of the licensee's written commitments to the Commission.
