j Document Control Desk Page 3 Restatement of the Violation Section 6.8.1 of the Technical Specification requires establishing and implementing written procedures and administrative policies that meet the requirements of Sections 5.1 and 5.3 of ANSI N18.7-1972 and Appendix "A" of Regulatory Guide 1.33 (1972).
Contrary to the above, the electronic calibrations of the liquid radwaste effluents radiation monitor performed prior to and on May 5, 1989, were performed without a written and approved procedure.
Cause of the Violation The electronic calibrations of the liquid radwaste effluent radiation monitor (LRERM) were performed prior to and on May 5, 1989 without the use of an approved controlled procedure as a result of not having a procedure available.
I A surveillance test existed to perform the radioactive source calibrition l
required by Technical Specifications (Tech Specs).
The survelliance test is performed by chemistry personnel, if this test fails, as was the case in the May 5, 1989 event, a maintenance request is generated and Instrumentation and l
Control (l&C) personnel perform an electronic calibration. On May 5, 1989, the electronic calibration was performed in accordance with the controlled vendor manual rather than an approved controlled procedure.
Corrective Steps Taken and Results Achieved An I&C controlled procedure was approved on 1/23/90.
This procedure covers the electronic calibration of the LRERM.
Similar Tec' Spec instrumentation was reviewed to determine if controlled and approved calibration procedures existed. This resulted in the generation of a controlled procedure for the calibration of the Main Stack Noble Gas Monitor on 2/26/91.
Corrective Steps Which Will Be Taken To Avoid further Violations l
In addition to the corrective actions identified above, an I&C surveillance l
procedure was generated for the tRERM.
This procedure requires that a yearly electronic calibration of the LRERM be performed regardless of the results of the yearly radioactive source calibration surveillance.
This procedure was l
approved by the Plant Operations Review Committee on 4/23/91.
I Date When Full Compliance Will Be Achieved Full compliance will be achieved upon the next performance of the electronic calibration of the LRERM which is scheduled to be completed by 6/30/91.
This l
calibration will utilize the new surveillance procedure and the I&C procedure l
as required.
