On July 16, the Unit 1 stack monitor was out of service; the inspector verified grab samples were being run every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> as required by the Technical Specification Unit 2 operated at or near 100% power during the majority of the inspection period except for a reduction to 27% power on July 18, 1986, to replace a leaking gland on "B" main feedwater regulating valve. The unit returr.ad to 100% power on July 20, 198 . Monthly Maintenance (62703)

Station maintenance . activities affecting safety related systems and components were observed / reviewed, to ascertain that the activities were conducted in accordance with approved procedures, regulatory guides and industry codes or standards and in conformance with Technical Specification (Closed) Unresolved Item 333/86-13-04 (see paragraph 8 of 50-338/86-17 and 50-339/86-17 report). A meeting was held with the superintendent of maintenance concerning the failure of 1-CH-P-1B. The licensee was not able to determine the root cause of the failure. The motor was replaced after refurbishment by Westinghouse and periodic test 14.2 was run on July 14, 1986. The periodic test showed that the pump was still in a vibration alert requiring more frequent surveillance. Since no violation or deviation is evident this item is considered close Work Requests The inspector requested and received a list of outstanding open safety related work requests which totaled 1,790. These requests can be broken down as follows: Programmatic - 911; Outage Related - 399; All Modes - 48 A review of this list indicates several priority 1 and priority 2 work requests are still open, although they are listed as outage related and were identified before the last outage. An example is charging pump 1-CH-P-1B referenced in inspection report 338, 339/86-17, Section 8 which had an outstanding work order dated April 16, 1985, for high vibration in the pum ~

This work order was identified as priority 2 which, according to Admini-strative Procedure 16.5, " Work Requests", is required to be started within one week. However, this work order was not accomplished until the pump failed, due to a lack of lubrication (cause unknown), in April of 198 Other examples are the Accumulator drain valves 1-SI-122 "A" Accumulator; 1-SI-135 "B" Accumulator, and 1-SI-156 "C" Accumulator which have priority 2 work orders written in August 1984, identifying that the valves leak b These work orders still have not been worke The inspectors are concerned that outstanding work requests may have caused problems that could have been avoided. A review of the work requests revealed a work order approved on May 1, 1986, to make a permanent repair to the packing on "B" Main Feedwater Regulating Valve. On June 29, 1986,

Unit 2 tripped as a result of a fault on a 230 kv line feeding the #2 main 500 kv bus. The work order in question was not accomplished during this outage and on July 18, 1986, the Unit had to be ramped down to 27% power to repack the "B" Main Feedwater Regulating Valve. The inspector also reviewed a work request indicating a need for cleaning the component cooling water-heat exchangers dated March 17, 1983. These work requests are still outstanding with the exception of 2-CC-E-1A which has been cleaned. The licensee has experienced difficulties in maintaining containment temperature during hot weather and the cleaning of the component cooling water heat exchangers could help alleviate this proble The inspectors are concerned that important work requests get lost in the large backlog of work requests and consequently, the proper priority mayLnot be given to completing the work. The inspectors will continue to review,the safety related work orders to determine if there is a failure 'of the licensee to take prompt corrective action. This will be identified as an Unresolved Item 338, 339/86-18-01 pending further inspector revie The licensee presently has a program in place to review the- backlog of work requests. The inspectors will monitor the progress made on reducing the number of safety related and non-safety related work request Miscellaneous Maintenance The inspector witnessed weld repair of Unit 2 blow down tank he'ade m On July 23, 1986, the inspector observed repair of mechanical seal on 1-CH-P-1C using maintenance procedure MMP-C-CH-2. This pump is out'of servic Unit 2 CH-P-1B remains out of service. The motor has been sent off site for diagnosis and repair. The inspectors will followup on the cause of failur No violations or deviations were identifie . Monthly Surveillance The inspector observed / reviewed TS required testing and verified that testing was performed in accordance with adequate procedures, that test instrumentation was calibrated, that limiting conditions for operation (LCO)

were met and that any deficiencies identified were properly reviewed and resolve ,

The inspector observed a check of 1H Diesel Generator Overspeed backup trip switch, procedure IMP-P-1-PROC-13 The inspector also observed the procedure for calibration of diesel generator 1H Jacket L.0. Discharge Temperature IMP-P-1-PROC-14 The tast of uninterruptable power supply for the security system was observed on July 17. The test was run satisfactoril s

Calorimetric calculation for Unit I was reviewed by the inspector on July 16. The action status logs for Unit 1 and Unit 2 were also reviewe On July 16, the stack gas monitor, Vent B was out of servic The inspector reviewed the grab sample data taken by health physics on an eight-hour basi On July 21, the inspector reviewed 1-PT-37, Radiation Monitoring Equipment Chec The following four Unit 1, radiation monitors are out of service: SW 107 " Component Cooling Heat Exchanger Service Water" Cables loose. Work request dated 3/29/8 RMS 161 " Containment" Service window stuck open. Work request dated 4/10/8 RMS 162 " Manipulator Crane" Work request dated 4/12/8 RMS 264 "In Core Instrument Area" Work request dated 9/9/85.

The inspector reviewed the 1986 periodic tests for all Unit 1 and Unit 2 component cooling water pumps and service water pump No problems were found.

. No violations or deviations were identifie . ESF System Walkdown The following selected ESF systems were verified operable by performing a walkdown of the accessible and essential portions of the systems on July 22, 23, 24, and 30, 1986.

Through log review and plant tours, the inspectors verified compliance with selected TS and Limiting Conditions for Operations requirement On a regular basis, radiation work permits (RWP) were reviewed and the specific work activity was monitored to assure the activities were being conducted per the RWPs. Selected radiation protection instruments were periodically checked and equipment operability and calibration frequency was

.

verifie The inspectors kept informed, on a daily basis, of overall status of both units and of any significant safety matter related to plant operation Discussions were held with plant management and various members of the operations staff on a regular basis. Selected portions of operating logs and data sheets were reviewed dail The inspectors conducted various plant tours and made frequent visits to the Control Room. Observations included: witnessing work activities in progress; verifying the status of operating and standby safety systems and equipment;

confirming valve positions, instrument and recorder readings, annuciator alarms; and housekeepin No violations or deviations were identifie . Safeguards Inspection (71707)

In the course of the monthly activities, the resident inspectors included a review of the licensee's physical security progra The performance of various shifts of the security force was observed in the conduct of daily activities to include: protected and vital areas access controls, searching of personnel, packages and vehicles; badge issuance and retrieval; escorting of visitors; patrols and compensatory posts. In addition, the resident inspectors observed protected area lighting, protected and vital areas barrier integrity and verified an interface between the security organiza-tion and operations or maintenance. Specifically, the resident inspectors witnessed the test of the uninterruptable power supply for the security syste No violations or deviations were identified.
