Licensee Action on Previous Inspection Findings (Closed) Violation (50-267/8205-01) Inadvertent Radioactive Liquid Waste Release. The surveillance procedure used for liquid waste releases, SR 5.8.2bc-M, has been modified to include an independent valve position verificatio . Operational Safety Verification The NRC inspector reviewed licensee activities to ascertain that the facility is being operated safely and in conformance with regulatory requirements, and the licensee's management control system is effectively discharging its responsibilities for continued safe operation. The review was conducted by direct observation of activities, tours of the facility, interviews and discussion with licensee personnel, independent verification of safety system status and limiting condition for operations, and review of facility record >

The operability of selected systems or portions of systems were verified by walkdown of the accessible portions. The NRC inspector verified the operability of the Decontamination and Radioactive Liquid Waste System No problems were identified during the system walkdown Procedures were also reviewed and implementation observed for Gaseous Effluent Releases No. 618 and 623 and Liquid Waste Release No. 553. The releases appeared to have been made in a satisfactory manne On May 21, 1982, the NRC inspector monitored an unplanned release of radioactive gases that resulted from the inadvertent closure of V-63232, C-6301/6301S Discharge Tie Line, which occurred at approximately 1:22 MDT. This event was subsequently reported to the NRC as an Unusual Event at 3:15 p.m. MDT, resulting in the issuance of PNO-IV-82-19 by Region IV on May 24, 1982. The reactor building was administrative 1y evacuated of all nonessential personnel at 1:25 p.m. MDT, and at 3:45 p.m. MDT, unlimited access to the reactor building was authorize This event resulted in three workers receiving minor contamination and a release out of the plant stack of approximately 52 microcuries of Cs 138 and Rb 88, whose MPC is 1 E-6 microcuries per milliliter. The maximum activity indicated inside the reactor building was reported at 1:40 p.m. MDT, to be 5.6 E-7 microcuries per millilite The NRC inspector determined that this event was apparently caused from a lack of the same type of controls that the licensee places on safety-related activities. System 63, " Radioactive Gas Waste System," is classified by the licensee as nonsafety-related and is not afforded the same controls as does a safety-related syste As a result, the NRC inspector determined that the failure to use a procedure to vent the "A" Gas Waste Compressor Containment Tank had resulted in the inadvertent closure of the cross connect valve V-63232 and the opening of a valve which was under clearance control to be in the shut position. This resulted in the release of gaseous radioactivity through the manhole of the containment tank and into the reactor building. The inspector determined that the licensee does not have a procedure for venting the gas waste compressor containment tank The NRC inspector informed the licensee of the above problems. The licensee stated that the issuance of a newly approved administrative procedure for nonsafety-related maintenance work control would resolve the problems noted above. The NRC inspector has no further questions in this are On June 3, 1982, G. L. Madsen met with 3. R. Lee, Vice President Electric Production to discuss the Region IV concerns regarding past radioactive gas releases which were attributable to personnel error or lack of control for activities on systems other than those normally classified as safety-related. Mr. Lee indicated a similar concern and that corrective actions were being considere , No violations or deviations were identifie _ _ _ _ _ _ _ _ _ _ _ J
