(0 pen) Open Item (338/79-03-0?), Verification of Respirator Qualification.
Health Physics has established a respirator qualifications log.
Instruc-tions for use of the log,:ere not in an approved procedure. The HP Super-visor stated that the instructions would be included in an HP Admiuistrative Procedure by January 1.
(Closed) Open Item (338/79-03-04)., Annual Retraining in Respiratory Pro-tection. This was an additional example of noncompliance item C, Inspec-tion Report No. 50-338/79-08, which was addressed in VEPCO's response dated June 19, 1979, and reviewed and closed in Inspection Report No. 50-338/79-36.
The inspector had no further questions.
(Closed) Infraction (338/79-11-01, 339/79-16-01), Release of Radioactivity to an Unrestricted Area. An inspector reviewed corrective actions, as discussed in VEPCC,s response dated April 10, 1979, and had no further questions.
(open) Open Item (338/79-11-0I, 339/79-16-02), Evaluate Cause and Duration of Leaking Relief Valves.
de licensee has completed the evaluation and will submit an update to I1R 79-024. % s item remains open pending receipt and review of that updated report.
(Open) Open Item (339/79-20-01), Reevaluate Radiation Monitoring System Calibration Procedures. A licensee representative stated the procedures have been revised to inc?ude a two-point source calibration. This item remains open pending a review of the procedures by the inspector.
(0 pen) Open Item (339/79-20-02), Evaluate Containment Air Monitois for Representative Sampling. Licensee representatives said that Plant Engineering is currently evaluating pipe runs, bends, etc.
4.
Unresolved Items No new unresolved items were identified during this inspection.
5.
Unit 2 Radiation Monitoring System An inspector reviewed the completed 2-P0-10, Radiation Monitoring System, as well as selected RMS instrument calibration procedure completed data sheets. The inspector determined that the preoperational testing and calibrations were performed in accordance with the approved procedures, and any deviations were adequately reviewed and resolved. The inspector noted several references over an extended period of time to an inoperable multi-point recorder for RMS data. At the exit interview, the Technical Services Superintendent said that he would review the status of that recorder to insure operability prior to criticality. The inspector had no further questions.

6.
Surveillance of Reactor Coolant and Secondary Water An inspector reviewed Chemistry Logs for the period 7/27/79 through a.
9/12/79 and determined that the licensee met both the RC. chemistry limits of Technical Specification Table 3.4-1 and the analysis fre-quencies of Technical Specification Table 4.4-3.
b.
By review of Chemistry Logs for the period 7/4/79 through 9/12/79, an inspector determined that the secondary coolant was within the speci-fied activity limits of Technical Specification 3.7.1.4, and the sample analysis frequency met or exceeded that required by Technical Specification Table 4.7-1.
This period coincides with the period during which a steam generator tube leak had been identified.
By review of Chemistry Logs for the period 6/30/79 through 9/12/79, an c.
inspector determined that the primary coolant radioactivity sample and analysis program met or exceeded all requirements of Technical Speci-fication Table 4.4-4.
This review also revealed no data which exceeded the specific activity limits of Technical Specification 3.4.8.
On September 6, 1979, the licensee initiated a Deviation Report, after identifying that the RC activity exceeded 1 microcurie / gram.for about 11 hours1.273148e-4 days <br />0.00306 hours <br />1.818783e-5 weeks <br />4.1855e-6 months <br /> on September 23, 1978, and the requirement (Technical Speci-fication 6.9.2) for a special report was overlooked. A licensee representative said that a 30-day report will be sent to the NRC, and that chemistry personnel were being reinstructed regarding data review.
The inspector had no further questions.
7.
Radioactive Waste Processing, Packaging, and Shipping The licensee continues to use the Chem-Nuclear Systems, Inc., de-a.
mineralization system for processing liquid waste, with temporary rubber " jumper" hoses connecting the system to plant piping.
This was previously discussed in RII Inspection Report No. 50-336/78-28. A licensee representative stated that Design Change 78-67, which in-cludes permanent piping of this system and was submitted in October 1978, is still retained at the Corporate Office. The inspector stated that long term use of the rubber hose was not good practice. The Station Manager stated that he would determine the status of the design change (338/79-35-01).
b.
In July, 1979, the licensee identified a small steam generator tube leak. This has resulted in low level contarrination of powdex resin removed from the full-flow demineralizers of the secondary water system. This resin is being transferred to 55 gallon drums and, in some cases, resin liners, for dewatering and shipment to a licensed burial facility.
.
An inspector discussed IE Bulletin No. 79-19, " Packaging of Low-Level c.
Radioactive Waste for Transport and Burial", with licensee management.
The licensee's response to this bulletin was still in preparation.

The inspector emphasized that management approved procedures should cover all aspects of radwaste activities including drumming, dewatering resin, verification of dewatering, etc. The inspector also stressed the importance of a member of station management having the responsi-bility and authority to plan and coordinate radwaste activities. The Station Manager acknowledged the inspector's comments. The licensee's response to IEB No. 79-19, and implementation, will be reviewed during a subsequent inspection.
8.
Health Physics Coverage for Unit 1 Outage The first Unit I refueling outage is due to start in early October and is planned to last 3 to 4 months. Licensee representatives said that station health physics personnel would be assigned to 12 hour1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> shifts, seven days /
week, with one day off about every three weeks.
The inspector expressed concern that working this schedule for an extended period of time could lead to fatigue and result in degradation of radiological safety.
Licen-see management acknowledged the inspector's concerns, and stated at the exit interview that a proposal co provide contract HP technicians would be solicited promptly.
The inspector stated that the question of adequate and effective HP coverage would be reviewed during the outage (338/79-35-02).
9.
Followup on IE Circulars IE Circular 79-09, " Occurrences of Split or Punctured Regulator Diaphragms in Certain Self-Contained Breathing Apparatus".
IE Circular 79-15, " Bursting of High Pressure Hose and Malfunction of Relief Valve and 0-Ring in Certain Self-Contained Breathing Apparatus".
The above circulars described problems identified with certain Scott Air Pac, Presur-Pak, and SurvivAir breathing apparatus. Discussions with health physics personnel revealed that none of these units are used at North Anna Station. The inspector had no further questions.
10.
Followup on IE Information Notices TN 79-07, " Rupture of Rad Waste Tanks" a.
The licensee's evaluation of Unit 1 and 2 actions to be taken has not been completed.
VEPCO has requested of Stone & Webster that, for North Anna 3 and 4, the radwaste bottoms system should be designed and the boron evaporator bottoms system should be modified such that the feed flow to the bottoms tanks should be terminated by the tank high level signals.
b.
IN 79-08, " Interconnection of Contaminated Systems With Service Air Systems Used as the Source of Breathing Air" The licensee's evaluation of this topic has not been completed. As yet, no supplied air system is used at North Anna for breathing air.
Y
-5-
.
The licensee was considering use of the service air system for breath-ing air in the future. However, as a result of the potential problem described in this Information Notice, as well as the fact that the service air compressor intakes are located in a potentially contamina-ted area (top floor of auxiliary building), the licensee is reevalua-ting the method to be used for supplying breathing air.
IN 79-09, " Spill of Radioactively Contaminated Resin" c.
The licensee's evaluation centered on the Chem-Nuclear Systems, Inc.,
liquid waste processing system. An inspector reviewed this evaluation and had a questions except that related to the design change as discussed in Paragraph i.a above.
