Inspection Summary:
Inspection on July 3, 1985, (Report No. 50-272/85-17 and 50-311/85-19)
Areas Inspected:
Special reactive inspection to review licensee reported problems with waste gas tank sampling and control of contaminated tool Results:
No violations of radiological requirements were identifie DETAILS 1.0 Persons Contacted During the course of this special inspection the following personnel were contacted or interviewed: Licensee Personnel
- L. Miller, Assistant General Manager, Salem Operation
- J. Trejo, Radiation Protection Manager
- J. 0 1Connor, Radiation Protection Engineer
- J. Clancy, Senior Radiological Engineer G. Dzieuba, Technical Supervisor - Chemistry
- G. Slaby, Senior Chemistry Supervisor V. Morales, Contract Engineer, Rad. Pro. Services
- Attended the Exit Meeting on July 3, 198.2 NRC Personnel R. Borchardt, Resident Inspector 2.0 Purpose The purpose of this special inspection was to review the circumstances and corrective action relative to licensee identified problems reported on July 2, 1985:
Improper sampling of Unit 1 and Unit 2 waste gas decay tanks,
Inadequate surveys of potentially contaminated tool.0 Sampling of Waste Gas Decay Tanks Technical Specification Appendix B, Section 2.3.4 and Table 2.3-2 require sampling of waste gas decay tanks prior to release and continuous vent stack monitoring during the releas Limits on release rate and total activity are provided in Technical Specification Appendix B, Section 2. Instructions for sampling the gas decay tanks are provided in licensee procedure CH-3.5.01 Samples are normally drawn via the Hydrogen/Oxygen Gas Analyzer syste This system was recently relocated and repiped in an attempt to resolve problem with condensatio In further attempts to obtain representative gaseous activity grab sample, the licenses provided for alternate sampling point.

On April 12, 1985, a On-the-Spot Change was incorporated into procedure CH-3.5.012 to allow sampling from Panel 108 (a panel of pressure gauges that shows pressure in each decay tank).
However, the gauges do not connect directly to the tanks but receive a compressed air signal from a pressure transduce Therefore, the sample obtained at the panel consisted of 11 clean 11 ai The licensee discovered this error on July 1, 1985, and deleted the On-the-Spot Chang All discharges were monitored and recorded by the stack monitor (R-16) and verified by a redundant stack monitor (R-41).
All 36 batch releases of waste gas from Units 1 and 2 between April 12 and July 1, 1985, appear to be well within Technical Specification limits based on preliminary licensee calculatio The licensee indicated that a Licensee Event Report will be submitted for this matte The licenseee 1 s investigation and corrective action will be reviewed in a future inspection (50-272/85-17-01 and 50-311/85-19-01).
The inspector concluded that there were no unmonitored releases from the waste gas decay tanks and no radiological hazard to the publi However, the inadequate control and engineering review of the On-the-Spot change to the sampling procedure will be reviewed by the Resident Inspecto.0 Contamination Survey of Tools The licensee has established criteria for unconditional release of potentially contaminated equipment in procedure RP4.00 In June, during the recovery from an outage, a few instances were reported of tools released from the control point, resurveyed in the tool crib, and found to have slightly contaminated spots above the procedural limit for unconditional relase of materials.(1000 DPM/100cm2
~~)
An HP supervisor was sent to an offsite contractor (Catalytic) tool center to resurvey tools and equipment that had been shipped off-sit Two tools were found with small areas contaminated to slightly above the licensee 1 s limit (Approximately 2000 DPM/100cm2
~P)
The licensee has subsequently established a policy that all tools, and equipment must be resurveyed by Radiation Protection personnel prior to removal from the sit The inspector concluded that this action will enhance the licensees control of radioactive materia.0 Exit Interview At the conclusion of the special inspection on July 3, 1985, the inspector met with licensee personnel denoted in Section 1.0 to discuss the scope and findings of the inspectio At no time during this inspection was written material provided to the licensee by the inspector.
