The OPERABILITY of the seismic instrumentation ensures that sufficient capability is available to promptly determine the magnitude of a seismic event

and evaluate the response of those features important to safety. This capability is required to permit comparison of the measured response to that used in the design basis for the facility.

3/4.3.3.4 METEOROLOGICAL INSTRUMENTATION The OPERABILITY of the meteorological instrumentation ensures that j sufficient meteorological data is available for estimating potential radiation i doses to the public as a result of routine or accidental release of radioactive

! materials 'o the atmosphere. This capability is required to evaluate the need 3 for initiating protective measures to protect the health and safety of the

! public. This instrumentation is consistent with the recommendations of 3

Regulatory Guide 1.23 "Onsite Meteorological Programs," except for the

recommendations regarding the minimum accuracies for the instrumentation to i monitor air temperature - delta T and wind speed (when wind speeds are greater

! than 5 mph).
