EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT J SUPPLEMENTAL INFORMATION FIRST HALF 1987 Re ulato Limits A. Fission and Activation Gases in Gaseous Effluent:

1. The average release rate of fission and activation gases is regulated by the dose limits of 10CFR50 Appendix I. The air dose to areas at and beyond the site boundary due to noble gases released in-gaseous effluents per unit shall be limited during any calendar quarter to < 5 mrad for gamma radiation and < 10 mrad for beta radiation; and during any calendar year to < 10 mrad for gamma radiation and < 20 mrad for beta radiation.

B and C. Iodines and Particulates with half lives greater than 8 days in gaseous effluents.

1. The average release rate of iodines and particulates in gaseous effluent is regulated by the dose limits of 10CFR50 Appendix I. The

,dose to a member of the public from radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases with half live greater than 8 days in gaseous effluent ~

released per unit to area at and beyond the site boundary shall be limited to any organ during any calendar quarter to < 7.5 mrem, and during any calendar year to < 15 mrem.

D. Liquid Effluents

1. The average release rate of radioactive liquid effluents is regulated by the dose limits of 10CFR50 Appendix I. The doses or dose commitment to a member of the public from radioactive materials in liquid effluents released from each unit to unrestricted areas shall be limited during any calendar quarter to < 1.5 mrem to the total body and < 5 mrem to any organ and, during any calendar year to < 3 mrem to the total body and < 10 mrem to any organ.

EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION FIRST HALF 1987 Maximum Permissible Concentrations.

A. Fission and Activation Gases in Gaseous Effluent

1. The instantaneous release rate of fission and activation gases is regulated by the dose rate limit of 10CFR20 Appendix B. The dose rate at any time to areas at and beyond the site boundary due to noble gases released in gaseous effluents from the site shall be limited to < 500 mrem/year to the total body and < 3000 mrem/year to the skin.
2. The BFN Offsite Dose Calculation Manual (ODCM) determines the maximum noble gas release rate based upon the dose rate limits in II.A.1. The instantaneous noble gas release rates are limited by the following equation:

gl + g2 < 1 0.15 14.4 Ql = The release rate from the building exhaust vents in Ci/sec.

Q2 = The release rate from the main stack in Ci/sec.

BSC Iodines and Particulates with Half Lives Greater than 8 Days in Gaseous Effluents

1. The instantaneous release rate of particulates and iodines is regulated by the dose rate limit of 10CFR20 Appendix B. The dose rate at any time to areas at and beyond the site boundary due to I-131, I-133, H-3 and particulates with greater than eight days half-lives released in gaseous effluents from the site shall be limited to <1500 mrem/yr to any organ.
2. The BFN ODCM determines the maximum particulate and iodine release rate based upon the dose rate limit of II. B and C.l. The instantaneous iodine and particulate release rates are limited by the following equation:

Q3 + g4 <1 2.19 35.7 Q3 = The release rate from the building exhaust vents in pCi/sec Q4 = The release rate from the main stack in pCi/sec.

EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT 0 SUPPLEMENTAL INFORMATION FIRST HALF 1987 D. Liquid Effluents

1. The concentration of radionuclides in liquid effluents released at any time from the site to unrestricted areas shall be limited to the concentrations specified in 10CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained.

noble gases.

2. For dissolved or entrained noble gases, the concentration shall be limited to 2E-4 pCi/ml total activity.

~ 1 III. 'verage Energy Not applicable IV. Measurements and A roximations of Total Radioactivit A. Fission and Activation Gases:

Noble gases in the building vent and stack, gaseous effluent are continuously monitored. The flow rate of the stack is continuously monitored and the building vent effluent flow rates are calculated once a shift based on the configuration of operating exhaust fans. The flow rate data is consolidated weekly to determine the volume of airborne effluent released from the plant. The noble gas monitor data is consolidated monthly to determine the total curies of noble gases released during the month.

2. Gas grab samples are taken,and analyzed monthly to determine the relative noble gas activity concentrations. This information is used to apportion the total curies of noble gases released between different noble gas radionuclides.
3. The tritium concentration is determined by the analysis of a monthly grab sample for each release point.

BGC Iodines and Particulates Iodines and particulates are continuously sampled on impregnated charcoal filters and particulate filters, respectively. The charcoal and particulate samples are replaced at least weekly and analyzed to determine specific activity concentrations. The specific activity concentrations and vent flow rate data are used weekly to verify that release rate limits were not exceeded. The specific activity concentrations and total volume of gaseous effluent are used on a monthly basis to determine the total curies of each particulate and iodine released during the month.

EFFLUENT AND WASTE DISPOSAL SEMIANNUAL REPORT SUPPLEMENTAL INFORMATION FIRST HALF 1987 IV. Measurements and A roximations of Total Radioactivit (Continued)

2. The gross alpha concentration is determined by analysis of a monthly particulate filter composite sample and strontium -89 and

-90 are determined by analysis of a quarterly particulate filter composite sample for each release point.

D. Liquid Effluents

1. The gamma ray emitting radionuclide concentrations are determined for each batch by gamma ray spectroscopy analysis of a grab sample. The allowable release rate is calculated for each batch based upon the known dilution flow. The flow rate of the liquid effluent is continuously monitored and the tota1 volume released in each batch is determined. The total gamma activity released in each batch is determined by multilying the radionuclide concentrations by the total.

volume discharged. The total gamma activity released during the month is then determined by summing the gamma activity content of each batch discharged during the month.

2. The gross alpha and tritium concentrations are measured on a monthly composite sample. The strontium -89 and -90 and iron -55 are measured

~

on a quarterly composite sample.
