The requirements of Equation (2) are then met as follows:

Y+(A) = MPCfF + f\

\f / .

Since, by definition, Y > X and Y(A) > X(A), then (c) = I(A) < MPC[F + f

( f a The setpoint concentration (c) can then be converted to a setpoint count rate value by use of the monitor calibration factor.

Setpoint (cpm) = "("i*} (3)

Cal. Factor (pCi/ml per cpm)

The setpoint for the dilution water flow (cooling tower blowdown) is 5000 gpm from either cooling tower basin. The setpoint for the LRW discharge flow can then be determined from:

F+f= (A) Y f MPC Sample calculations for determining the release concentration limits and setpoints are given in Section A.l.1 of Appendix A.

The Service Water System provides screened water from the cooling tower basin for cooling plant systems and equipment.

The Residual Heat Removal (RHR) Service Water System provides water from the Engineered Safeguard Service Water (ESSW) spray pond to the RHR heat exchangers. In post-accident conditions, RHR Service Water can supply water for vessel and containment flooding. The Service Water and RHR Service Water Systems are not normal pathways for liquid effluents. Radiation monitors are in place on these systems to provide indication of leaks across heat exchangers into the service water. The high JAN 201984

- 8b -

~

radiation setpoints for these monitors are set at 2E-5 pCi/cc cesium-137 equivalent. Considering the radionuclides predominant in SSES liquid effluents, e.g., Co-58, Co-60, Fe-59,

. Mn-54 and Cr-51, use of a setpoint based on the Cs-137 MPC is conservative based on the following parameters: -

1) photon abundance (85%)
2) magnitude of applicable MPC (2E-5 pCi/cc)

Because Service Water & RHR Service Water are not normal release pathways for liquid effluents, no credit should be taken for possible dilution scenarios. All service water should be maintained below 2E-5 pCi/cc Cs-137 equivalent.

MONITORING INSTRUMENTATION CHANNELS SHOWN IN TABLE 3.3.7.11-1 SHALL BE OPERABLE WITH THEIR ALARM / TRIP SETPOINTS SET TO ENSURE THAT THE LIMITS OF SPECIFICATION 3.11.2.1 ARE NOT EXCEEDED. THE ALARM / TRIP SETPOINTS OF THESE CHANNELS SHALL BE DETERMINED IN ACCORDANCE WITH THE METHODOLOGY AND PARAMETERS IN THE ODCli.

Noble gas activity monitors. iodine samplers, and practiculate samplers are present on the reactor building ventilation system (Units 1 and 2), the turbine building ventilation system (Units 1 and 2), and the standby gas treatment system. Effluent system flow rate and sampler flow rate are measured on all of the systems allowing the vent monitor microgrocessor to calculate release rates based on measured flow rates. Precautions, limitations, and setpoints applicable to the operation of the SSES gaseous effluent monitors are provided in the applicable plant Procedures. Setpoints are conservatively established for each ventilation effluent monitor so that the instantaneous dose

~

rates corresponding to 10 CFR 20 annual dose limits in unrestricted areas will not be exceeded. Conservatism is to be incorporated into the determination of each setpoint to account for:

JAN 201984

o -
1. All expo,are pathways of significance at the critical receptor locations; 2 Dose contributions to critical receptors from multiple release points; and
3. Dose contributions from major radioisotopes expected to be present in gaseous effluents.

The general methodology for establishing plant ventilation gaseous effluent monitor setpoints is based upon vent release rates (pCi/sec) derived from site-specific meteorological

. dispersion conditions, vent flow rates, and expected radioiso-topic mixtures in the gaseous effluents. The vent release rate can then ,be converted to cpm depcoding upon the particular monitor's method of operation, sampling rate, and detection -

efficiency. It is not practical to apply alarn/ trip setpoints to integrating radiation monitors sensitive to radiciodines, radioactive materials in particulate form, or radionuclides other than noble gases. Therefore, only the noble gas activity monitors in the five ventilation systems at the SSES will have established setpoints.

The calculated alarm and trip action setpoints for each noble gas ventilation effluent monitor and flow measurement device must satisfy the following equation for whole body dose:

3 500 (4) q, i*

(K )(X/Q)y and by the following equation for skin dose:

It is appropriate that these noble gas radionucides be used as the reference isotopes for establishing the particular monitor setpoints.

Vent flow rates and sample flow rates are monitored and recorded for each of the five SSES release points. The measured flow rates are used to calculate vent concentrations and release ,

rates. Flow channel setpoints are set at 10% and 90% of the calibrated sensor ranges to provide indication of possibly abnormal flow rates.
