c. The provisions of cificattin3.0.4 not applicable.

SURVEILLANCE REQUIREMENTS 4.3.8.1 The provisions of Specifi tion 0.4 are not applicable.

4.3.8.2 The above required turbine ov speed protection system shall be demonstrated OPERA 8LE: .

a. At least once per 7 days y cyc1 each of the following valves through at least one c lete cyc1 rom the running pos' tion:
1) Four high press e turbine stop y ves,
2) Four low pre ure turbine intamedia stop valves, and
3) Four low ssure turbine intercept valv . lI
b. At least per 31 days by cycling the four h1 pressure turbine control v vos th ough at least one complete cyc e rom the running position
c. At I of t once per la months by performance of a CHAf81EL turbine overspeed protection system.

ISRATION Il

d. least once per 40 months by disassembling at least one of he above valves and performing a visual and surface inspect 1 of h of Il all valve seats, disks and stems and verifying no unacceptable or excessive corrosion. If unacceptable flaws or excessive corros n are found, all other valves of that type shall be inspected. \

INSTRUMENTATION BASES HONITORING INSTRUMENTATION (Continued) 3/4.3.7.11 RADIOACTIVE 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 and adjusted in accord-ance with the methodology and parameters in the 00CM to ensure that the alarm /

trip will occur prior to exceeding the limits of 10 CFR Part 20. This instru-mentation also includes provisions for monitoring the concentrations of poten-tially explosive gas mixtures in the waste gas hc1 dup 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. .In addition, the.redioactive release paths of the Fuel Building Ventilation Exhaust, Main Plant Exhaust Duct, and the Radwast Building Ventilation Exhaust include post-accident monitors.

The containment ventilation system provides emergency containment heat removal as described in Bases 3/4.6.3. The feedwater system / main turbine trip system is initiated in the event of failure of the feedwater controller under maximum demand. ,
