1.

The second quarterly composite sample at location AM1 (East Fence) identified Co-60 with an activity of 5.24E-03 pCi/m3. Identification of Co-60 was likely to have occurred during the demolition of the Liquid Radwaste Building. The weekly sample results for alpha and beta particulate met the effluent acceptance criteria in the ODCM. The activity identified in the composite sample would not have resulted in a measurable dose to a member of the public and was well below the effluent concentration limits in 10 CFR 20, Appendix B, Table 2, Column

1. Offsite laboratory analysis of the composited filters reaffirmed that no significant release occurred and the onsite sampling and analytical protocols accurately reflect the HBPP effluents. This event was addressed in corrective action SAPN 1407196.

2.

Composite samples for first, second, third and fourth quarter ODCM Air Samples were analyzed by gamma spectroscopy. Sample analyses were performed by HBPP count room personnel. All samples met the LLD requirements of 6.0E-02 pCi/m3 for Cs-137.

3.

All LLD's were met for Gross Beta (required LLD 1.0E-02 Ci/m3).

4.

All samples reported as <MDA represent results that had no identified gamma peaks.

Year The baseline values for each location were obtained by averaging the readings at each location from 1977 through 1983. These values, however, were obtained using ion chambers instead of TLDs. The average annual values from 1977 through 1983 were Station 1 - 83.0 mRem, Station 2-79.8 mRem, Station 14-80.2 mRem, and Station 25-73.7 mRem.

Year The baseline values for the two areas were obtained by averaging the readings for each area from 1977 through 1983.

These values, however, were obtained using ion chambers instead of TLDs. The average annual value from 1977 through 1983 for the stations near the radwaste activities was 78.6 mRem and the average annual value for other onsite stations was 79.4 mRem.
