Review of Plant Operations A review of plant operations was conducted to ascertain whether facility operation was in conformance with the requirements established in Technical Specifications, 10 CFR, and administrative procedures, or licensee commit-ments discussed in correspondence to the Commission.
Included in the inspection were observation of control room activities, review of.iperational logs and records, and a tour of accessible areas.
Logs and records reviewed included:
Shift Supervisor Log (April 5 - July 11,1979)
Reactor Operators Log (April 5 - July 11, 1979)
Technical Specification Compliance Log (March 19 - July 11,1979)
Surveillance Logs 1-3 (February 25 - June 30, 1979)
Operating. Order Book Form 1 Log ((jumper log)
Plant Trouble Rcport During the tour of accessible areas, particular attention was directed to the following:
Monitoring Instrumentation Radiation Controls llousekeeping FJuid Leaks Piping Vibrations llanger/Scismic Restraints Clearance Tags Annunciators Control Room }bnning The inspector also witnessed performance of surveillance test 4.1.3.2.b.M, Feedwater Flow Test.
During observations in the control room, on July 10, 1979, at 2:00 p.m.,
the inspector noted that Recorder XVI 4102-1 for the circulating water makeup storage pond was not inking. A check of the chart showed that it had not been inking since at least 10:00 p.m. on July 8, 1979, and that the chart

had not been date stamped on July 9, 1979. Additionally, no Plant Trouble Report (PTR) had been written, as required by ADM 28, to report that the recorder was not working properly.
On July 13, 1979 at 8:15 a.m. this same instrument, XVI 4102-1 was again observed not to be inking and a check of the chart showed that it had not been inking since 2:00 p.m. on July 12, 1979 and although it was dated properly at 12:00 p.m. on July 12, 1979, no PTR had been written as required.
On July 11, 1979, at 8:45 a.m., the blue pen which records PCRV surface temperature of instrument TR 4637 was observed not to be inking. A check of the chart indicated that the pen had not been inking since 2:00 p.m. on July 10, 1979, had been date stamped at 12:00 p.m. on July 10, 1979, but no PTR had been written as required.
Technical Specification AC7.4.a requires in part that, " Written Procedures shall be established, implemented and maintained.
." and Administrative
..
Procedure No. 28 for Data Logs, Data Sheets and Charts, Section 3.2 states that a responsible person shall check the charts or recorders at least once per shift to be sure that the recorders are inking and that at midnight they are to stamp each chart with a new date and if the recorder is not working properly, write a Plant Trouble Report.
Contrary to these re-quirements, the charts were apparently not checked for inking as required, PTR's were not written as required and in one instance the chart was not dated as required. The failure to fulfill these requirements were dis-cussed with the licensee at which time it was pointed out that this was an apparent item of nonconformance for failure to follow procedures and was considered an infraction.
During the inspector's review of data logs, data sheets and charts the inspector determined that the temperature readings of all the fuel storage wells were not taken at the times and dates as follows, nor were any reasons given on the data sheets for omission of the readings.
3/31/79 1400 6/10/79 1600, 1800, 2000, 2200 6/14/79 0600, 0800, 1000, 1200, 1400 6/26/79 1400 Technical Specification AC7.4a requires in part that " Written Procedures shall be established implemented and maintained.
." and Administrative Procc-
..
dure No. 28, Section 2.3 requires that the person responsible for taking data shall take the data at specified intervals unless specifically exempted by an operations order and that all log sheets are to be completed (dates, times, names, etc.) by the operator unless specifically exempt by an operations order.

The Operations Order for System 14 dated March 26, 1979, states that " Readings of temperatures of all fuel storage wells shall be taken at such times as indicated by the attached log anytime there is new fuel or irradiated fuel in the storage wells.
Log the temperature and initial in appropriate columns."
Contrary to the above requirements, no data was taken for the dates and times specified, nor were they exempted by an operations order. The failure to log this data was discussed with the licensee who was informed that this was an apparent item of nonconformance for failure to follow procedures and was considered an infraction.
The inspector had no additional questions in this area.
5.
Maintenance The inspector reviewed selected maintenance activities to determine that these activities met acceptable maintenance practices, the licensee's applicable administrative and maintenance procedures, and were in accordance with Technical Specifications.
The activities reviewed were as follows:
PTR 5-908 Repair of V-11752 PTR 5-823 Repair of V-11677 PTR 5-511 Removal of M-11701 to Verify Proper Distance Between Rupture Diaphragm and Cutter PTR 5-105 Repair or Replace Bistable Board A3 0 counterclockwise limit Bistable PTR 4-592 Repair Switch for H-1302 PTR 2-316 Perform Annual Inspection of H-1402 PTR 1-201 Perform Work Described in CN 4387 During review of the data package for PTR 5-908 it was determined that item 9.6.2 on page 1 of MP-4 and all of page 2 of FT-4, Repair and Modifi-cation of Velan Globe Valves, had been left blank.
Item 9.6.2 is " Tack Welds Replaced", and page 2 contains space for completing a listing of tools and equipment that require calibration, materials utilized for cleaning, purchase orders and bulk materials and an inspection report.
A review of the PTR indicated that the tack welds had been replaced and that an inspection had been made, however, this was not indicated in the appropriate sections of MP-4 nor were there any indications that the information was not applicable.
Technical Specification AC7.4.a requires in part that, " Written procedures shall be established, implemented and maintained.
." and Administration Procedures
..
No. 12 for Maintenance and Repair Procedures, Section 5.1.3(10)f states that

work / test instructions include the following instruction to personnel per-forming work and/or tests,
" Sign off, where applicable, all records and data sheets.
Indicate not applicable (N/A) on all sign off blanks associated with steps that were not required to complete the necessary repairs."
The failure to comply with these requirements as indicated above were discussed with the licensee who was informed that this was an apparent items of non-conformance for failure to follow procedures and was considered an infraction.
The inspector had no additional questions this area.
6.
Exit Interview An exit interview was conducted with representatives of the licensee on July 13, 1979, at the conclusion of the inspection. At the interview, the inspector discussed the findings indicated in the previous paragraphs. The licensee acknowledged these findings.
