IN51KUMENhATICN SASES 3/4.3.3.3.5EISMIC INSTRUMENTATION The OPERABILITY of the seismic instrumentation ensures that suf ficient capability is available to promptly determine the magnitude of a seismic event and evaluate the response of nose features impcrtant to safety.
This ca:2bility is required to permit comparison of the measured response to that used in the design basis for the facility to determine if plant shutdown is required pursuant to Appendix "A" of 10 CFR Part 100.
The instrumentation is consist:nt with the recommendations of Regulatory Guide 1.12, " Instrumentation for Earthquakes," April 1974.
3/4.3.3.4 METEOPOLOGICAL INS'RUMENTATION The OPERABILITY of the meteorological instrumentation ensures that sufficient meteorological data is available for estimating potential radiation doses to the puolic as a result of routine or accidental release of radioactive materials to the atmosphere.
This caoability is required to evaluate the need for initiating protective measures to protect the health and safety of the public and is consistent with the recommendations of Regulatory Guide 1.23, "Onsite Meteorological Programs," Fecruary 1972.
3/4.3.3.5 REMOTE SHUTOCWN INSTRUMENTATICN The OPERABILITY of the remote shutdown instrumentation ensures that sufficient capability is available to permit shutdown and maintenance of HOT STANDBY of the f acility from locations outside of the control room.
This capability is required in the event control room habitability is lost and is consistent with General Design Criteria 19 of 10 CFR 50.
3/4.3.3.6 ACCIDENT MONITORING INSTRUMENTATION The OPERASILITY of the accident monitoring instrumentation ensures that suf ficient information is available on selected plant parameters to monitor and assess these variables following an accident.
This capability is consistent with the recommendations of Regulatory Guide 1.97, " Instrumentation for Lignt-Water-Coolea Nuclear Power Plants to Assess Plant and Environs Conditions Uuring and Following an Accident." December 1980 and NUREG-0737, " Clarification of TMI Action Plan Requirements," November,1980.
