Dear Dr. Murley:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. OPR-73 Docket No. 50-320 Inspection Report 86-09 Inspection Report 50-320/86-09, dated September 21, 1986, identified one (1) j item of non-compliance. This item was previously reported to the NRC via l
Licensee Event Report (LER) 86-06.
The attached GPU Nuclear response to the l

I41C NOTICE OF VIOLATION As a result of the inspection conducted July 19 through August 29, 1986, and in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (Enforcement Policy 1986), the following violation was identified:
Technical Specifications, Appendix A, Section 6.11 requires that personnel radiation protection shall be consistent with the requirements of 10 CFR 20 and the Radiation Protection Plan.
The Radiation Protection Plan, 1000-ADM-4010.01, Revision 1, dated May 1, 1986, permits equipment to be released for unrestricted use when the removable beta-gamma contamination is less than 1000 disintegrations per minute per 100 square centimeters of surface area (dpm/100 cm2),
Contrary to the above, on July 15, 1986, a camera tripod found in an unrestricted area had removable beta-gamma contamination between 8000 and 12,000 dpm/100 cm2, This is a Severity Level IV violation (Supplement IV).
GPU NUCLEAR RESPONSE At 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on Tuesday, July 15, 1986, during a routine survey by GPU Nuclear Radiological Controls personnel, a contaminated camera tripod was discovered in a scrap metal dumpster in an unrestricted area. The duty Group Radiological Controls Supervisor was notified and the dumpster was posted as a radiologically controlled area. The tripod was removed from the dumpster and moved inside the protected area to be surveyed. Smear samples indicated that the removable surface contamination level of the tripod ranged from 8,000 to 12,000 dpm/100 cm2 (beta-gamma) with a maximum exposure rate of 0.8 mR/hr (gamma). The camera tripod and dumpster were decontaminated and released for unrestriced use.
In order to identify the causal details of this event, an investigation was initiated which included the following actions:
o An inquiry was held which determined that the dumpster was last surveyed on July 7, 1986, at which time no radiological contamination was detected. Therefore, it was concluded that the tripod was placed in the dumpster sometime between July 7,1986 and July 15, 1986.
o Personnel were interviewed and purchasing records were reviewed in order to determine if there was evidence of a missing tripod.
o Workers in shops in the vicinity of the dumpster were interviewed.
o Interviews were conducted with drivers of vehicles transiting through the protected area between July 7,1986 and July 15, 1986, who routinely carry trash or contaminated materials.
o Decontamination workers who removed stored materials from the 281' elevation of the Auxiliary Building were interviewed.
l l
c o
11aste Management personnel responsible for equipment storage areas were interviewed.
Based on the above actions, GPU Nuclear was unable to identify the origin of the tripod, the method of transport from the controlled area to the unrestricted area, or the identify of the responsible person (s).
To stress the importance of controlling contaminated material, the following corrective actions have been taken:
o The event was discussed with Radiological Controls Personnel to stress the importance of ensuring proper surveys when transporting equipnent/ materials from a controlled area to an unrestricted area.
o The event was discussed with TMI-2 Department Managers at the Office of Director staff meeting on July 24, 1986.
o The event was highlighted at the monthly TMI-2 Radiological Awareness Meeting on July 16, 1986, and August 13, 1986.
GPU Nuclear believes that this highlighting of the event to TMI-2 personnel will stress the importance of controlling contaminated material and that full compliance has been achieved.
