Office of Inspection and Enforcement RII: JNG Region II - Suite 2900 50-321/50-366 101 Marietta Street, tM Inspection Report Atlanta, Georgia 30323 85-15 ATTENTION:
Dr. J. Nelson Grace GENTLEMEN:
The referenced inspection report transmitted by letter of June 14, 1985, identified a violation of NRC recuirements.
We have reviewed the violation and offer the following response.
VIOLATION Technical Specification 6.8.1 recuires that written procedures be established, implemented and maintained covering the applicable procedures recomended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.
Regulatory Guide 1.33 reouires radiation protection procedures including procedures for contamination control.
Plant procedure HPP-8161, Eberline Model PCM-1 Portal Monitor Operation and Calibration, Section (G)(3)(1), recuires that the detector high voltage be increased to a value which is midway on the measured beta plateau.
The Eberline Model PCM-1 is an instrument used to frisk personnel for contamination.
Contrary to the above, the licensee failed to meet the procedural recuirement to increase the detector high voltage to a value which was midway on the measured beta plateau in that PCM #102 and PCM #108 had high voltages which were set 150 volts and 50 volts, respectively, below the knee of the beta plateau.
This is a Severity Level IV violation (Supplement IV).

Georgia Power d U. S. Nuclear Regulatory Commission Office of Inspection and Enforcement Region II - Suite 2900 July 8, 1985 Page Two Admission or denial of the alleged violation:
The violation occurred.
Reason for the violation:
The failure to follow plant procedure HfP-8161, Eberline Model PCM-1 Portal Monitor Operation and Calibration, was the result of personnel error.
Corrective steps which have been taken and the results achieved:
- 102 and PCM #108 were recalibrated on May 10, 1985, and the detector high voltages set at the midpoint of the measured beta plateau per procedure HNP-8161.
Supervisors instructed their technicians on plotting plateaus and properly determining the high voltage setpoint.
Procedure compliance was emphasized.
Corrective steps which will be taken to avoid further violations:
Procedure HNP-8161 will be revised by November 5, 1985 to clarify the setting of the detector high voltage.
An example plateau and blank graph will be added to the procedure.
Technicians will be recuired to plot the plateau to aid in setting the high voltage at the midpoint.
Date when full compliance was achieved:
Full compliance was achieved on May 10,1985.
Should there be any further concerns regarding this issue, please contact this office.
Very truly yours, f 7~ %
