'4.21.1 Coneentration Surveillance Renuirements The concentration of radioactive material at any time in liquid effluent released from the site shall be continuously monitored in accordance with Table 3.15-1.

Th'e liquid effluent continuous monitor having provisions for automatic i

termination of liquid releasts, as listed in Table 3.15-1, shall be used to 1,imit the concentration of radioactive material released at any time from the site to areas beyond the site boundary to the limits given in Specification 3.17.1.

The radioactivity concentration of each Retention Basin to be discharged shall l

be determined prior to release by sampling and analysis in accordance with Table 4.21-1, Item A.

The results of Retention Basin pre-release sample analyses shall be used with the calcu14tional methods described in the OFFSITE DOSE CALCULATION MANUAL (ODCH) to ensure that the concentration at the point of release is within the limits of Specification 3.17.1.

B1111 This Specification is provided to ensure that the concentration of radioactive materials released in liquid waste effluents from the site to areas beyond the site boundary will be less than the concent ation levels specified in 10 CFR l

Part 20 Appendix B, Table II, Column 2 for liquid effluent. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will result in exposures within the limits of 10 CFR Part 20.106 to HEMBER(S) 0F THE PUBLIC. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its HPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

There are no continuous releases of radioactive material in liquid effluents from the plant. All radioactive liquid effluent releases from the plant are by batch method, f

Dose Calculations i

Cumulative dose assessments associated with the release of radioactive i

liquid effluent shall be determined by sampling and analysis in accordance l

l with Table 4.21-1 Item B and calculations performed in accordance with the l

l methodology described in the ODCM at the following frequencies:

l a.

Prior to tb9 initiation of a release of radioactive liquid effluent from the A or 8 AHUT; and.

L b.

Upon verification of monthly composite analysis results for radioactive liquid effluent released from the A and B RHUTs.

A dose tracking system and administrative dose limits shall be established and maintained. With the 31-day dose projection in excess of the i

Specification 3.17.4 limits, adjust liquid effluent operating parameters to give reasonable assurance of compliance with the dose lir.its of f

Specification 3.17.2 (10 CFR 50, Appendix I dose guidelines) and mainta'.n radioactive liquid releases as low as is reasonably achievable.

W This specification is provided to implement the requirements of Sections

?

II.A. III.A. and IV.A of App ndix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix 1.

i Specification 4.21.2 provides the required operating flexibility and, at the same time, implements the guides set forth in Section IV.A of Appendix I which assures, by definition, that the releases of radioactive material in liquid effluents will be kept "as low as reasonably achievable." The dose calculation methodology in the ODCH implements the requirements in Section

[

III.A of Appendix ! that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the OOCH for calculating the doses due to the actual release rates of radioactive materitis in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Dose to Man from Routine i

Releases of Reactor Effluent for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977, and Regulatory Guide 1.13, " Estimating Aquatic Dispersion of Effluents from Accidental i
