16.7 l_N_STR_UMENTATION 16.7.3 METEOROLOGICAL INSTRUMENTATION i
v' COMMITMENT:
I a.
The meteorological monitoring instrumentation channels shown in Table 16.7-3A shall be OPERABLE.
APPLICABILITY:
At all times.
REMED' KL ACTION:
a.
With one or more required meteorological monitoring channels inoperable for more than 7 days, prepare and submit a Special Report to the Commission pursuant to Technical Specification 6.9.2 within the next 10 days outlining the cause of the malfunction and the plans for restoring the channel (s) to OPERABLE status.
l TESTING REQUIREMENTS:
a.
Each of the above meteorological monitoring instrumentation channels
[]
shall be demonstrated OPERABLE by the performance of a CHANNEL
(/
CHECK and Instrument Calibration operations at the frequencies shown in Table 16.7-3B.

I N/A BASES:
16.7-3 METEOROLOGICAL INSTRUMENTATION The OPERABILITY of the meteorologicalinstrumentation 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.

A CHANNEL CHECK, subsequent to any work performed. This will verify continuity of the signal cable between the sensor and signal processors.
5)
The Wind Speed Sensors and cup-sets or Wind Direction Sensors and Vanes do not require wind tunnel testing as an assembly.
