INSTRUMENTATION BASES 3/4.14.1 RADI0 ACTIVE LIQUID EFFLUENT INSTRUMENTATION The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarm / trip setpoints for these instruments shall be. calculated in accordance with the methods in the OFFSITE DOSE CALCULATION MANUAL (ODCM) to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.
3/4.14.2 -RADI0 ACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The alarm / trip setpoints for these instruments shall be calculated in accordance with the methods fn the ODCM to ensure that the alarm / trip will occur prior to exceeding the limits of 10 CFR Part 20.
The monitoring instrumentation includes provisions for monitoring (and controlling) the concentrations of potentially explosive gas mixtures in the main condenser offgas treatment system.
The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.
Surveillance frequencies for augmented ventilation systems are only required when the system is installed and releases are being made via that pathway. The_ augmented ventilation systems are designed to assist normal release paths for temperature control and reduction of excess noble gas concentrations.
Their use is oc a temporary basis only; i.e.,
they are not permanent modifications to tha plant.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to an individual at or beyond the exclusion area boundary to s 500 mrem / year to the total body or to s 3000 mrem / year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem / year, j
This specification applies to the release of gaseous effluents from all reactors at the site.
For units with shared radwaste treatment systems, the gaseous effluents from the shared system are proportioned among the units sharing that system.
l Sampling for augmented ventilation systems is only required when the system is installed.gnd releases are being made via that pathway.

3/4.15.2.2 DOSE, NOBLE GASES This specification is provided to implement the requirements of Sections II.8, III.A, and IV.A of Appendix I, 10 CFR Part 50.
The LCO implements the l
guides set forth in Section II.B of Appendix I.
The ACTION statements I
provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I, assuring that the releases of radioactive material in gaseous effluents will be kept ALARA.
The Surveillance Requirements implement the requirements in Section III.A of Appendix I, which state that conformance with the guides of Appendix I is to be shown by calculational procedures based on models and data such that the actual exposure of an individual through the appropriate pathways is unlikely to be substantially underestimated.
The dose calculations established in the OFFSITE DOSE CALCULATION MANUAL (00CM) for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents will be consistent with the methodology provided in Regulatory Guide 1.109, Calculation of Annual Doses to Man from Routine l
Releases of Reactor Effluents for the Purpose of Evaluating Compliance with l
10 CFR Part 50, Appendix I, Revision 1, October 1977; and Regulatory Guide 1.111, Methods for Estimating Atmosphere Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors, Revision 1, July 1977.
The ODCM equations provided for determining the air doses at the exclusion area boundary will be based upon the historical average atmospheric conditions. NUREG-0133 provides methods for dose calculaticns consistent with Regulatory Guides 1.109 and 1.111.
