BIG ROCK POINT SEMIANNUAL EFFLUENT RELEASE REPORT JANUARY - JUNE 1986 i This report provides information relating-to radioactive effluent releases and solid radioactive waste disposal operations'of the Big Rock Point Plant during the period of January through June 1986 in the format contained in Plant Technical Specification 6.9.2.2. The January - June 1986 Semiannual Effluent Release Report reflects effluent Technical Specification changes effective January 1, 1986. Big Rock Point has been on-line for mostlof this reporting. period. 1. Supplemental Information a. Batch Release Information relating to batch and continuous releases of liquid and gaseous effluents is provided in Table HP 10.3-1. l b. Abnormal Releases A small tube leak within the emergency condenser is suspected to have developed during the 1st Quarter. Based on a calculated leak rate of 3 1.1 liters per day,.the following activity levels are reported as having been released to the atmosphere (via the condenser vent): 1st Quarter - 0.80 mci tritium 27 mci fission gases 1 2nd Quarter - 0.80 mci tritium J 36 mci fission gases These calculated activity amounts have been included with the Semi-i annual Radioactive Effluent Release Report totals. The emergency l condenser is to be thoroughly inspected and tested during the next scheduled maintenance outage. 2. Gaseous Effluents Table HP 10.3-2 lists and summarizes all gaseous radioactive effluents released during the reporting period. There was no unidentified beta i released. The maximum noble gas release rate for the first and second ) quarters were 2.09E+03 and 2.42E+03 uCi/second, respectively. 3. Liquid Effluents I -Table HP 10.3-3 lists and summarizes all liquid radioactive effluents-released during the reporting period. The unidentified beta was 2.35% of the total release. The maximum liquid effluent release concentration for the first and second quarters were 9.00E-08 and 7.00E-08 uCi/ml. MIO687-0034A-HP01-NLO4
4. Solid Waste Solid radwaste classification, sources, volume shipped, curie and nuclide content are detailed in Table HP 10.3-4. 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 calculated using GASPAR and LADTAP computer program codes. The first and second quarter values for curies released were input for each nucilde and summarized as follows: The maximum offsite air doses at site boundary due to noble gases a. were 8.69E-02 and 1.13E-01 millirads beta for the first and second quarters respectively. The maximum offsite air doses for gamma were 1.35E-01 and 1.75E-01 millirads, respectively. b. The most restrictive organ dose to an individual in an unrestricted area (based on identified critical receptors) from gaseous effluents ) (tritium, particulate and iodine) was the infant thyroid. Doses were j 1.38E-02 and 1.73E-02 millirem for the first and second quarters. c. The maximum total body doses to individuals in unrestricted water-related exposure pathways were 8.02E-03 and 3.42E-03 millirem for first and second quarters, respectively, with the maximum organ dose being (child bone) 1.17E-02 and 6.14E-03 millirem per quarter, respectively. d. Integrated total body doses to the general population and average doses to individuals within the population from liquid effluent releases within a distance of 50 miles from site boundary were 3.54E-03 and 1.87E-03 manRem for the first and second quarters, respectively, and 2.30E-05 and 1.21E-05 millirem per quarter, respectively, Integrated total body doses to the general population and average e. doses to individuals within the population from gaseous effluent releases within a distance of 50 miles from site boundary were 1.30E-01 and 1.72E-01 manRem for the first and second quarters respectively with 8.44E-04 and 1.12E-03 millirem per quarter respectively, f. There were no entrained noble gas isotopes present in any liquid releases for this reporting period. 6. Process Control Program (PCP) There were no changes to the PCP this reporting period.
