I. SlM4ARY During the period of this repart, tne Nuclear Safety and Cbn-pliance Cbamittee met montnly with its Staff, twice witn Quirman John O' leary ard President Pnil Clark, aM once with the GPt3 03rporate '

Board. 'Ibe Qxmittee visited the Oyster Creek Station twi and D1I-l once. 'Ihe meetings with Mr. O' leary aM Mr. Clark were for the purpose of reporting observations made by the dSOC Staff in tne course of its evaluations which might be beneficial to management to improve operations but had no safety or c:xpliance significance.

'Ibe Staff's evaluations were concerned with a range of station activities that could affect the safe operation of T41-1 and Oyster Creek. 'Iheir purpose was to determine whether each activity is being performed safely ard in cmpliance with governing requirements and sourd operating practices. 'Ihe Staff developed its evaluations through direct observations at operating stations, interviews with various managers and supervisors, and review of relevant written policies, procedures, and reports.

At T4I-1, the Staff wrducted evaluations incitding operations, preventive and corrective maintenance, chemistry, records management, mcmitment tracking, radiological controls, special processes control, design change processirg, accreditation of training, procurement ard control of repair parts, and several specific events.

At Oyster Creek, the Staff conducted evaluations incitding training facilities ard prcgram, preventive maintenance ard surveil-lance, chemistry, radiological controls, control rocan audits, non-mntrol rocm shift operations, instructor training, mntrol of special processes, control of regulatory ccramitments, normal ard emergency operating procedures, procurement and control of parts, records management, and several specific events.

In general, tne Staff found safety attitudes ard practices to be satisfactory. Station operating personnel, supervisors, ard managers exhibit professionalism ard competence in the implementation of policies. Staff evaluation of two scrams which occurred durire Oyster Creek startup in late 1984 revealed a need for improved adherence to procedures and strengthened post-repair maintenance practices. NSCC notes that snagement's responses to these events were prcrapt ad appropriate.

Ma:u 15, 1984, (Clark, 4/gement's response to the NSCC's report of October 1/85) is roted by the NS NSCC enmurages the GPLI4 management to redum response time.

Significant observations are reported in the followire sections on 711-1 and Oyster Creek.

II. IMI-l OBSERVATICLE

.' Oparations - (bntrol roaa activities are conducted in a professiomi manner witn an appropriate degree of formality.

Itintenan - Staff exhibits a professional attitude towards nuclear safety ard cxxpliance. Mministrative procedures are adegaate.

Gemistry - Department has staff, pro dures, and equipment to ensure adequate control. Qantinued management attention to calculational z:ethods for E oar and primary-to-secondarf leak rate is in order. The natural sulfate Mckground levels in cxandensate storage should continue to be examined.

Preventive Maintenance and Surveillance - Established programs are found satisfactory.

Fagulatorf Cbtrtitment Tracking - Tracking System in use is appropriate.

The percentage of past due items, however, exceeds corprate goals.

Radiological Cbntrols - Program is comprenensive and meets or exceeds all regulatory requirements for an operating plant. Improved com:aanications to personnel outside those in PNMIX4 is encouraged in the area of the Radiological Awareness Report system.

Soecial Processes Qantrol - 03ntrol of special processes is adequately administered. Efforts to c:xaplete the Cbrporate Welding Manual cn schedule are important.

Pro ssing of Design Gange Packages - This review, while nat yet ccraplete, shows adequate design configuration control. The area of welding procedures for certain materials is being further evaluated due to some inadequate welding results.

Accreditation of Training - NSCC notes that IMO accreditation was granted for five important operator, shift technical advisor, and radiological technician training programs.

Cbntrol Roczn Monitoring - IM extent of control rocIn monitoring sub-stantially exceeds regulatorf requirements; however, no adverse effects due to this monitoring on control rocra operations were observed.

Fbliowing startup, this should be ::enitored to assure there is na distraction of operators frcxn operatin3 functicns.

, III. OYSTER CRZEK OBSERVATICMS (bre Soray Injection, Oct. 29, 1964 - Difficulty in following an extensive cne-time temporary procedure change was the rmt cause of this event. Management attention to irgrove in this area is apparent.

Reactor Scrams, Oct. 31 aM Dec. 3,1984 'Ibe NSCC believes that these scrams were bath related to Oyster Creek's long maintenance outage aM the resulting lack of operating opportunity. In botn cases, operator and plant responses to the scrams were proper aM effective. Root causes have been determined and appropriate remedial steps taken.

Preventive Maintenan aM Surveillance 'Ihere is a need to strengthen the priority system to assure that important-to-safety equipnent is regularly assigned higher priority than other equipaent.

Drywell Ventilation Valve Modifications - A special NSCC investigation of modifications performed on four main drywell ventilation inlet and outlet valves found that the modifistion decision was pntlent and tnat it was effectively performed.

Q1emistry - Department has adequate tecnnical and administrative proce-dures to ensure safe operations of chemistry-related systems. Upgrade of laboratorf facilities, now in progress, extend the ability to detect chlorides and sulphates at very low concentraticns.

Cantrol Room Aalits - (batrol Room auditing activities are well planned and scheduled. Auditing reports reflect cxzpliance with check lists and QA plans.

Instructor Training and Qualification - Current instructors are quali-fied in acm rdan with appropriate regulations. 'Ihere is a potential snortage of Senior Reactor Operator li nsed instructors. Until addi-tional instructors are qualified, any significant increase in projected training schedules would be un rtain.

Remrds Management 'Ibe records management system is in order.

. Cbrrective Maintenan - Atninistrative controls are adequate.

Control of Smcial Processes (welding, brazing, heat treating, solder-ing, cutting, and burning) 'Ihe program in place is effective and meets the requirements of the OA plan and the intent of 10CER50 Appendix B.

Procurement and Cbntrol of Parts - The processes in use are acceptable.

The mnaept of shelf life vs assuran of materials being acceptable

. prior to use bears examination.

~

Normal and Emrgency Operating Premdures - Megtate written guidance is providea to the operators for safe opration o2 plant eystems and

- components. 'Ihe mechanism for keeping operators informed of new or changed pro dures appears to be satisfactory.

Radiological Cbntrols - Mequate radiological controls exist. Improve-ments in following procedures and timely response to awareness ard deficiency reports can be made.

Ibn-Cantrol Foom Shift Operations 'Ihese operations were found to be in compliance. Trainee progress throtx3h the operator requalification program suggests the need for attention.

Regulatorf Cbctnitments - Ib safety or carapliance findings were roted.

'Ihe numoer of overdue items are being vicprously pursued to bring them in line with corporate goals.
