INSTRUMENTATION BASES RADIOACTIVE LIQUID EFFLUENT MONITORING INSTRUMENTATION (Continued)

Subsequent CHANNEL CALIBRATIONS will be performed using sources that have been related to the initial calibration in order to ensure that the detector is still operational, but the sources need not span the full ranges used in the initial CHANNEL CALIBRATION.

3/4.3.5.9 RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent monitoring 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 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 and 64 of Appendix A to 10 CFR Part 50.

The main condenser air ejector monitoring instrumentation, the main condenser offgas treatment system monitor, and the explosive gas monitoring instrumen-tation shown in Table 3.3.5.9-1 are not considered effluent monitoring instrumentation in the same sense as the other instrumentation listed in the table. Therefore, their alarm / trip setpoints are not necessarily set to ensure that the limits of Specification 3.11.2.1 are not exceeded.

The main condenser air ejector monitoring instrumentation channels are l

provided to monitor and control gross radioactivity removed from the main condenser. The alarm / trip setpointo for the main condenser air ejector monitor are set to ensure that the limits of Specification 3.11.2.7 are not exceeded. The alarm / trip setpoint for this monitor shall be calculated in accordance with NRC approved methods to provide reasonable assurance that the potential total body accident dose will not exceed a fraction of the limits specified in 10 CFR Part 100.

This specification also includes provisions for monitoring the concentrations l

of potentially explosive gas mixtures in the offgas treatment system (hydrogen l

monitors).

"Without delay" implies that the operator, upon determining the limiting condition for operation is being exceeded, takes the next appropriate action to comply with the specification.
