INSTRUMENTATION BASES 3/4.3.3.2 MOVABLE INCORE DETECTORS -

The OPERABILITY of the movable incore detectors with the specified minimum complement of equipment ensures that the measurements obtained from use of this system accurately represent the spatial neutron flux distribution of the core. The OPERABILITY of this system is demonstratea by irradiating each detector used and determinirv! the acceptability of its voltage curve.

For the purpose of measuring Fo(Z) or F% a fullincore flux map is used. Quarter-core flux maps, as defined in WCAP-8648, June 1976, may be used in recalibraG0n of the Excore Neutron Flux Detection System, and full incore flux maps or symmetric incore thimbles may be used for monitoring the QUADRANT POWER TILT RATIO when one Power Range channelis inoperable.

UNTIL TIIE NRC APPROVES THE RELOCATION AS REQUESTED IN NOC-AE-000367.

LIMITING CONDITION FOR OPERATION 3.3.3.4 The meteorological monitoring instrumentation channels shown in Table 3.3-8 shall be OPERABLE.

APPLICABILITY: At all times.

ACTION:

a.

With one or more required meteorological monitoring channels inoperable for j

more than 7 days, prepare and submit a Special Report to the Commission l

pursuant to Specification 6.9.2 within the next 10 days outlining the cause of the i

malfunction and the plans for restoring the channel (s) to OPERABLE status. This ACTION may be applicable to both units simultaneously.

l b.

The provisions of Specification 3.0.3 are not applicable.

SURVEILLANCE REQUIREMENTS 4.3.3.4 Each of the above meteorological monitoring instrumentation channels shall be demonstrated OPERABLE by the performance of the CHANNEL CHECK and CHANNEL CALIBRATION at the frequencies shown in Table 4.3-5.

INSTRUMENTATION BASES 3/4.3.3.3 SEISMIC INSTRUMENTATION 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 1

measured response to that used in the design basis for the facility to determine if plant shutdown i

is required pursuant to Appendix A of 10 CFR Part 100. The instmmentation is consistent with the recommendations of Regulatory Guide 1.12, " Instrumentation for Earthquakes," April 1974.

3/4.3 3.4 METEGROLOGICAL INSTRUMENTATION The OPERABILITY of the meteorological instmmentation ensures that sufficient meteorological data are available for estimating potential radiation doses to the public as a result of routine or accidental release of radioactive materials to the atmosphere. This capability 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," February 1972.

3/4.3.3.7 CHEMICAL DETECTION SYSTEMS DELETED.

i 3/4.3.4 TURBINE OVERSPEED PROTECTION I

This specification is provided to ensure that the turbine overspeed protection instrumentation and the turbine speed control valves are OPERABLE and will protect the turbine I

from excessive overspeed. Protection from turbine excessive overspeed is required since excessive overspeed of the turbine could generate potentially damaging missiles which could impact and damage safety-related components, equipment, or structures.
