PALISADES NUCLEAR PLANT SEMIANNUAL EFFLUENT RELEASE REPORT July - December 1986 This report provides information relating to radioactive effluent releases and solid radioactive waste disposal operations of the Palisades Plant during the
'eriod of July through December 1986 in the format contained in Plant Tech-nical Specification 6.9.3.la.
The July - December 1986 semiannual ef fluent release report reflects effluent Technical Specification changes. effective January 1, 1985. Due to the extended maintenance outage since May 19, 1986, both the third and fourth quarter gaseous effluent releases reflect only residual activity levels.
1.
SUPPLEMENTAL INFORMATION A.
BATCH RELEASES Information relating to batch releases of liquid and gaseous effluent is provided in Table HP 10.5-1.
B.
ABNORKAL RELEASES l
None.
2.
CASEOUS EFFLUENTS Table HP 10.5-2 lists and summarizes all gaseous radioactive effluents released during the reporting period. The unidentified beta was 9.30E-03% of the total release.
3.
LIQUID EFFLUENTS Tab'e HP 10.5-3 lists and summarizes all liquid radioactive ef fluents released during the reporting period. The unidentified beta was 1.02E-02% of the total release.
4.
SOLID WASTE Solid radwaste classification, sources, volume shipped, curie and nuclide content are detailed in Table HP 10.5-4.
All radwaste shipments were made to either Barnwell, South Carolina or Richland, Washington for burial.
5.
SUMMARY
OF RADIOLOGICAL IMPACT ON MAN Potential doses to individuals and populations were :alculated using CASPAR and LADTAP computer program codes. The third and fourth quarter values for curies released were input for each nuclide and summarized as follows:
