! The OPERABILITT of the radiation monitoring channels ensures that 1) the

! raaiation levels are continually measured in the areas served by tne

! individual channals and 2) the alara or automatic action is initiated when the

racistion level trip setpoint is exceeded.

2/4.3.3.0 INCORE DETECTORS

! The OPERABILITT of the incore detectors ensures that the sessurements cotained j from use ci this system accurately represent the spatial neutron flux i districution of the reactor core. See Bases Figures 3-1 and 3-2 for examples l

of acceptable minimum incore detector arrangements.

i 3/4.3.3.3 SEISMIC INSULUMENTATION

} The OPERASILITT of the seismic instrumentation ensures that sufficiant capacility is available to promptly determine the ensaitude of a seismic event so tnat the response of those featuras important to safety may be evaluated, i

This capability is required to 9:rnit comparison of the measured response to

! that used in the design basis for the facility. This instrumentation is

' consistent with the recommendations of Regulatory Guide 1.12 " Instrumentation j for Eartaquakes," April 1974.

l 3/4.3.3.4 METEOROLOGICAL INSTRUNINTATION The OP3ARILITT of the meteorological instrumentation ensures that sufficient meteorological data is available for estinating potential radiation doses to j the public as a result of routine or accidental release of radioactive j saterials to the atmosphere. This capability is required to evaluate the need for initiating protective measures to protect the health and safety of the public. This instrumentation is consistent with the recoemendatioss of

Regulatory Guida 1.23 "Onsite Meteorological Programs," February 1972.
