Persons Contacted
"E. Weeks, Plant Superintendent
- W. Rapp, Power Plant Engineer
- R. Twiddy, Quality Control Engineer D. Voss, Supervisor of Operations The inspectors also interviewed other licensee employees during the course of the inspection including control operators, shif t foremen,
,mcenoLsem=n, anc office personnel.
- Denotes those present at the exit interview on August 17, 1979.
2.
Plant Operations The major items remaining to be completed during the outage have been deferred until resolution of the geologic / seismic issues at the plant. No major work was observed to be in progress during this inspection.
The inspectors walked through areas of the plant to observe activities in progress, to inspect the general state of housekeeping, and to check that monitoring instrumentation was reading or recording as required. Temperature and nuclear monitoring indications appeared normal.
The inspectors observed that neutron monitoring was being performed in accordance with Technical Specification requirements.
Normal radiation control practices were in effect including the estabiishment of barrier controls.
No unusual fluid leaks or piping vibrations were observed. The ventilation systems, nuclear instrumentation, component cooling system, and reactor protection systems were in operation during this tour.
Representative samples of the following logs and records from March-July,1979 were examined and discussed with licensee personnel:
Control Operator's Log Shift Foremen's Log Jumper Log Clearance Logs Plant Staff Review Committee Minutes No items of noncompliance or deviations were identified.

3.
Annual Review of Quality Assurance Program One personnel change occurred in the QA prograr affecting the Humboldt site. The onsite QA engineer has been withdrawn.
His responsibilities have been transferred in part to the onsite quality control engineer and the remainder to the generel office quality assurance department.

_2_ . There were several substantial changes to the program made in the par,t year. The inspectors examined these changes and the associated revised procedures and verified that they conform to the appreved program, applicable codes, standards, and regulatory guides. The most significant change was deleting the Qualified Supplier List and endorsing the Coodinating Agency for Supplier Evaluation (CASE) Program. The inspectors discussed the changes and their imple-mentation with the onsite QC engineer.
flo items of noncompliance or deviations were identified.
4.
Surveillance The inspectors reviewed the Control Room Surveillance Schedule and the following surveillance procedures: OTP 8: Refueling Building Leak Rate Test, Gas Treatment System Check, and Refueling Duilding Isolation Monitor Check OTP 9: Liquid Poison System Check OTP 14C: Fire and Low Pressure Core Flood Pump Test All of the completed surveillance tests were accomplished in accordance with approved written procedures.
The test results were in accordance with Technical Specification requirements.
11 0 items of noncompliance or deviations were identified.
5.
Procurement The inspectors toured the warehouse facility to verify safety-related material and spare parts were being handled, stored, and identified in accordance with approved procedures.
In addition, the inspectors reviewed the following: a.
Procedure D-4: Procurement of Safety-Related Equipment, Services and Materials b.
QA Procedure 3.1: Procurement of Items end Services c.
Procurement Document Review Log (8/78-8/79) The above procedures were reviewed to ensure the procurement pro-gram meets the requirements of the Quality Assurance Program.
Implementation of the procurement program was verified by selecting three safety-related items and checking that procurement documents were prepared, tne vendor's qualification was current, ad vendor ' supplied documentation of quality was available.
flo items of noncompliance or deviations were identified.

-3- . . Reportable Event Followup 6.
The circumstances and ccrrective action described in the Licensee Event Reports listed below were verified by the inspectors through an examination of selected records, interviews with responsible personnel, and examination of equipment. The events have been reviewed by the licensee and reporting requirements were met.
78-04, Revision 1, Low Flow in Gas Treatment System: Licensee perf ormed a troubleshooting program to determine the cause for the low flow condition. After the ceramic packing in the gas absorption column was replaced, the flow rate returned to normal.
Licensee attributes the cause of the low flow rate to De fouling of Ine packing.
(Ciosec) 79-01, Yearly ILRT Missed: Since Humboldt Bay Unit-3 has been shutdown for seisnic upgrading, the licensee decided to. Smit a Technical Specification char,ge to defer the yearly ILRT requirement until :.tartup. Amendment No.18 to the Technical Specifications was approved on July 13, 1979 making the ILRT deferment effective on January 25, 1979.
The ILRT was due on January 26, 1979; therefore, no noncompliance occurred.
(Closed) 79-02, Late Performance of Surveillance Test: Licensee revised surveillance schedule and placed responsibility for meeting surveillance schedules on the onsite Q.C. engineer.
(Clored) 7.
Followup on IE Circulars and Bulletins The inspectors verified that the plant staff had reciived the IE Circulars and Bulletins listed below. An examination of records and discussions with licensee representatives verified that appro-priate corrective action was identified or taken as follows: a.
