3.H.A LIQUID EFFLUENTS (cont'd) t 'ie guides of Appendix I he shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate patnways is unlikely to be sibstantially under-estimated. The equations specified la the ODCM for calculating the ooses due to the actual release

_ces of radioactive materials in liquid effluen*.s will be consistent with the methodology provided in Regulatory Guide 1.109, " Calculation of Annual Dosos to Man fram Routine Releases of Reactor Effluents for the Purpose of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977. NUREG-0133 provides methods far dose calculations consistent with Regulatory Guide, 1.109 and 1.113.

Specification 3.8.A.5 requites that the appropriate portions of the lieuid radwaste treatment systen be used when specified. This provides assurance that the releases of radf uactive materials in liquid effluents will be kept "as low as is reasonably achievable."

This specification implements thc requirements of 10 CFR Part 50.36a, General Desv;n Criterion 60 of Appendix A to 10 CFR Part 50 and design objective Secti an 11.D of Appenaix ! to 10 CFR Part 50.

The specified limits governit.g the use of appropriate portions of the liquid radwaste treatment system were specified as a suitabic fraction of the guide set f orth in Section 11. A of Appendix 1, 10 CFR Part 50, for liquid effluents Specification 3.8.A.6 requires submittal of a special report if the limiting values of Specification 3.8.A.5 are exceeded and unexpected failures of non-redundant radwaste processing equipment halt vaste treatment.

Specificacion 1.8.A.7 requires that suitable equipment to control and monitor the releases of radioactive materials in the liquid effluents are operating during any period when these releases are taking place.

3.8 B AIRBON E EFFLUENTS Specificatian 3.8.B.1 is provided to ensure that t'ae dose rate at any-time at the exclusion boundary from gaseous effluents from all units on the site will be within the annual dose limits of 10 CFR Part 20 for-unrestricted arean. The annual dose limits are the doses associated wi.th the concentrations of 10 CPR Part 20, Appe.. dix B, Table II.

These limite provide reasonable assurance that radioactive materi?1 discharged in gaseous effluents will not result in the exposure of an individaal in an unrestricted area, either within or outside the exclusion area boundary, to annual average concentrations exceeding the 11mfes specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR Part 20.106(b))

For individuals who may at times be within the exclusion area boundary, the occupancy of the individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the ex-clusion area boundary.

6.10 OFFSITE DOSE CALCULATION MANUAL (ODCM)

FUNCTION 6.10.1 The ODCM dee cibes the methodology and parameters used in the calculation of offsite doses due to radioactive gaseous and liquid effluents and in the calculation of gaseous and liquid effluent monitoring instrumentation alarm / trip secpoints consistent with the applicable LCO's contained in these Technical Specifications.

(Methodologins and calcula.

tional procedures acceptable to the Commission are contained in NUREG-O'.33.)

6.10.2 Changes to the ODCM shall be made by either of the following methods:

A.

Licensee initiated changes:

1.

Shall be submitted to the Commissior by includion in the Monthly operating Report pursuant to Specification 6.9.1.10 within 90 days of the date the change (s) was made ef fective v

and shall contain:

Y a.

Sufficiently detailed information to totally support the rationale for the change without benefit of additional or supplemental information.

Information submitted should consist of a package of those pages of the ODCM to be changed with each page numbered and provided with an approval and date box, together with appropriate analyses or evaluations justifying the change (s);

b.

a determination the the change will not reduce the accuracy or reliability of dose calculations or setpoint determinations; and c.

documentation of the fact that the change has been reviewed and found acceptable by PORC.

2.

Shall become effective upon a date specified and agreed to by PORC following their review and acceptance of the change (s).
