PALISADES NUCLEAR POWER PLANT RADIOACTIVE EFFLUENT AND WASTE DISPOSAL SEMI-ANNUAL REPORT JULY - DECEMBER 1979

• This report provides information relating to radioactive effluent releases and solid radioactive waste disposal operations of the Palisades Plant during the period of July through December 1979 in the format contained in plant Technical Specification Section 6.9.3.1.A.

1. Supplemental Information

a. Batch Releases Information relating to batch releases of liquid and gaseous effluents is provided in Table 1.

b. Abnormal Releases One abnormal gaseous release occurred during the reporting period totaling 0.569 Curies. The release a.mounted to less than 3% of the total gaseous releases during the reporting period. The maximum dose to off-site populations from this release is calculated to be less than 0.0002 mrem. No release limits were exceeded.

2. Gaseous Effluents Table 2a presents a summary of all gaseous radioactive effluents released during the period. Release totals for each radionuclide determined to be present in gaseous effluents are contained in Table 2b. The unidentified-

~ortion of the total release was 0.0009% of the total release.

3. Liauid Effluents Table 3a presents a summary of all liquid radioactive effluents released during the period. Release totals for each radionuclide determined to be presen~ in liquid effluents are contained in Table 3b. The unidentified portion of the total release was 0.01% of the total release.

4. Solid Waste Quantities of solid waste shipped off-site and the disposition of these shipments are presented in Table 4.

5. Radiological Impact on Man Potential doses to individuals and populations were calculated using effluent data contained in Tables 2 and 3, and the dose conversion factors contained in the i;ebruary/March 1979 Appendix I submittal.

a. Total body and significant organ doses to individuals in unrestricted areas from receiving water1 related exposure pathways were calculated to be less than 1 millirem:

b. The maximum off-site air doses due to beta and gamma radiation at loca-tions near ground level from gaseous effluents were calculated to be less than 1 millirad.

c. Organ doses to individuals in unrestricted areas from radioactive iodine and radioactive material in particulate form from the major pathways of exposure were calculated to be less than 1 millirem for any organ.

d. Total body doses to the population and average doses to individuals in the population from receiving water-related pathways to a distance of 50 miles from the site were calculated to be less than 1 manrem and 1 millirem, respectively.

e. Total body doses to the population and average doses to individuals in the population from gaseous effluents to a distance of 50 miles from the site were calculated to be less than 1 manrem and l millirem, res-pectively .
