INSTRUMENTATION I
BASES MONiiORING INSTRUMENTATION (Continued) 3/4.3.7.12 RADIOACTIVE GASEOUS EFFLUEkT MONITORING' INSTRUMENTATION, q
The radioactive gaseous effluent' monitoring instrumentation is provided
)
to monitor and' control, as applicable, the releases of radioactive materials q
in gaseous effluents during actual or potential releases of gaseous effluents.
The alarm / trip setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM utilizing the system design flow rates as specified in the ODCM, This conservative method
-is used because the Fermi 2 design does not include flow rate measurement -
devices. This will ensure the alarm / trip will occur prior to exceediry the limits of 10 CFR Part 20. This-instrumentation also includes provis'ons for monitoring and controlling the concentrations of potentially explos'.ve gas mixtures in the main condenser offgas treatment system. The OPERAr,ILITY and use of this instrumentation =is consistent with the requirements of General Design Criteria 60,, FN and 64 of Appendix A to 10 CFR Part 50.

s ecification is provided to ensure that the turbine overspeed protection s umentation and the turbine speed control valves are OPERABLE and will protec e from excessive overspeed.
Protection
- )
d from turbine excessive overspeed is no to protect safety related components, equipment, or structures. However, it in order to-
~
L improve overall plant reliability.
l 3/4.3.9 FEEDWATER/ MAIN TURBINE TRIP SYSTEMS ACTUATION INSTRUMENTATION l
The feedwater/ main turbine trip systems actuation instrumentation is provided to initiate action of the feedwater system / main turbine trip system in the event of a high' reactor vessel water level.due to failure of the
[
-feedwater controller under maximum demand.
