(Closed) Violation (259, 260, 296/82-06-01) Failure to follow procedur This violation identified six specific instances in which plant personnel failed to adhere to plant procedures. TVA responded to the overall violation stating that TVA has expanded considerable effort in improving management control system Since this violation, the number of violations involving failure to follow procedure has decreased significantly. This indicates that the improvement in the management control system has been positive. This item is considered closed; however, the inspectors will continue to monitor TVA's ptogress in this are (Closed) Deviation (259/82-12-04) Failure to update Muscle Shoals Emergency Control Center Implementing Procedure 10. The Division of Nuclear Power has combined all identified commitment dates into a single computerized Committment Control System to ensure commitment dates are met on schedul The inspector had no further questions as the procedure has been adequately revise (Closed) Open Item (259, 260, 296/82-12-05) Update MMI-6 to cover proper diesel engine filter maintenance. The licensee updated MMI-6 to include all diesel engine related filters on a preventive maintenance schedule. The inspector has no further question In the above area, no violations or deviations were identifie . Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptable or may involve violations or deviations. A new unresolved item is identified during the inspection and is discussed in paragraph . Operational Safety The inspectors kept informed on a daily basis of the overall plant status and any significant safety matters related to plant operations. Daily discussions were held each morning with plant management ard various members of the plant operating staf The inspectors made frequent visits to the control room such that each was visited at least daily when an inspector was on site. Observations included instrument readings, setpoints and recordings; status of operating systems; status and alignments of emergency standby systems; purpose of temporary tags on equipment controls and switches; annunciator alarms; adherence to procedures; adherence to limiting conditions for operations; temporary alterations in effect; daily journals and data sheet entries; and control room manning. This inspection activity also included numerous informal discussions with operators and their supervisor General plant tours were conducted on at least a weekly basis. Portions of the turbine building, each reactor building and outside areas were visite Observations included valve positions and system alignment; snubber and

. .

hanger conditions; instrument readings; housekeeping; radiation area con-trols; tag controls on equipment; work activities in progress; vital area controls, personnel badging, personnel search and escor Informal discus-sions were held with selected plant personnel in their functional areas during these tours. In addition a complete walkdown of the plant emergency D. C. power supply batteries was conducte During the walkdown of the Unit 3 battery board room, the inspector observed cable conduit support bracket bolts missing on pipe conduit running from the Unit 3 preferred A. C. bus transformer (37.5 KVA) to the Unit 3 bus A and B alternate source power box. The inspector informed plant management and an investigation was begun to ensure support requirements are properly me The inspector reviewed various workplans to determine when the supports were installed, but no workplans were located to describe the installation to date. This item will remain unresolved and followed up on future inspections. (296/82-18-01).

During an operational safety tour of the Unit I reactor building at 12:45 on July 13, 1982, the inspector observed a posted fire watch at the High Pressure Coolant Injection Pump Room not fully alert. The inspector notified the shift engineer and the plant safety engineer of his obser-vations. The plant safety engineer toured the area at 1318 and noted the firewatch to be apparently asleep. The firewatch was relieved of firewatch duties. The inspector considers this item closed due to prompt management attentio . Independent Inspection Effort During this report period, the licensee identified two surveillance instructions (SI) as being over-due for performance, SI 3.2.8 (Testing of HPCI and RCIC Vacuum Relief Valves) and SI 4.11.D-3 (Monthly Visual Inspection of Fire Protection). The inspector reviewed the licensee's method for identifying and tracking late si If an SI is not completed on the due date, Plant Services places the test on its Weekly Status Reports of sis. This list is distributed to plant management for actio If the SI is still over-due the next week, it is identified as being a repeat item but no reason is given for why it is over-due nor is there a system to adequately alert plant management to a potential proble In the case of SI 3.2.8, it appeared on the Weekly Status Report of sis three times before action was taken to perform the required test. In addition, this SI appeared on the Status of Routine Maintenance list, (which identifies over-due maintenance), four times before action was taken to perform the required work. This item will remain open pending the inspector's review of corrective action (259, 260, 296/82-18-02).

7. Bulletin Review Licensee action on the below listed bulletin was reviewed by a Region II inspector to determine if the evaluation and action taken was appropriate to satisfy the concerns described in the bulletin. The inspection consisted of records, drawings and procedure review and discussions with plant personne The below listed bulletin is cbnsidered closed on Units 1 and 3: IE Bulletin 79-27 " Loss of Non-Class IE Instrumentation and Control Power System Bus During Operation."

In the above area, no violations or deviations were identifie . Surveillance Testing Observation The inspectors observed the performance of the below listed surveillance procedures. The inspection consisted of a review of the procedure for technical adequacy, conformance to technical specifications, verification of test instrument calibration, observation on the conduct of the test, removal from service and return to service of the system and a review of test dat S.I. 4.2.D.1, Off-Gas Post Treatment Radiation Monitor S.I. 4.1.B.2, Reactor Water Level, Unit 3 S.I. 4.2.A.8, Group I isolation; Main Steam Line High Temperature, extensive review was performed for emergency technical specification changes evaluation, to allow operation with a failed switch in the untripped channel condition. The inspector verified that the instru-ment channel was in the tripped condition until emergency technical specification changes can be receive In the above area, no violations or deviations were identified.

l 9. Maintenance Observation

! During the report oeriod, the inspectors observed the below listed main-tenance activities for procedure adequacy, adherence to procedure, proper tagouts, adherence to Technical Specifications, radiological controls, and t

adherence to Quality Control hold points: Torus modifications Unit 2 i Electrical Maintenance Instruction 72, Checking the VS Relays on Speed l Sensing Panels on the 3B Diesel Generator

Electrical Maintenance Instruction 3, Unit 3 Diesel Generator Redundant

! Start Test.

In the above areas, no violations or deviations were identified.

10. Reportable Occurrence The below listed licensee event reports (LERs) were reviewed to determine if-the information provided met NRC. reporting requirements. The determination included adequacy of event description and corrective action taken or planned, existence of potential generic problems and the relative safety significance of each event. Additional inplant reviews and discussions with plant personnel as appropriate were conducted for those reports indicated by an asterisk:
