Meteorological Instrumentation 16.7-3 BASES The FUNCTIONALITY of the meteorological instrumentation ensures that sufficient meteorological data is 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, for wind speed, wind direction, and air temperature at two elevations. Precipitation is not required by Regulatory Guide 1.23, Revision 0. However, it is monitored since it is used by the model for offsite dose assessment calculations.

With respect to the control room chart recorder, the regulatory guide states:

Either analog (strip chart) or digital recording of data may be used as a basis for analysis. In lieu of providing redundant digital recorders, digital outputs may be supplemented by strip chart recorders to minimize possible loss of data due to instrument malfunction. Recorders (analog or digital) for wind direction and speed and temperature difference (two temperatures or one temperature difference measurement on a tower or mast) should be located in the reactor control room for use during plant operation.

Thus, the chart recorder in the control room is required in order to comply with the regulatory guide.

An instrument calibration will consist of the following test:

1) A bench based test, certification, and/or calibration of the tower mounted sensors for:
  • wind speed
  • wind direction
  • ambient and delta temperature RTDs
2) An instrument loop calibration from the input of the signal processors to the end devices. The identification of an out-of-tolerance condition or failure of a component within the instrument loop renders the channel non-functional until the component is calibrated or repaired/replaced.
3) For wind direction a line phase differential compensation will be performed, which includes the tower signal cable.
4) For precipitation, a measured volume of water will be poured into the sensor and the signal conditioner module's output verified correct.
5) A CHANNEL CHECK, subsequent to any work performed. This will verify continuity of the signal cable between the sensor and signal processors.
6) The wind speed sensors and cup-sets or wind direction sensors and vanes do not require wind tunnel testing as an assembly.

Meteorological Instrumentation 16.7-3 BASES (continued)

7) Replacement of cup-sets or vanes does not require an instrument calibration of the affected channel.

The greater than or equal to 90% annual data recovery requirement is to ensure that the meteorological instrumentation is maintained to minimize extended periods of instrument outage. The reporting cycle is a calendar year (January 1 through December 31). A 60-day period from the end of the calendar year is allowed for data reduction, validation, and data quality assurance, before the data recovery report is generated.

The 90% data recovery is a statistical analysis of the respective data for the required parameters. This analysis includes out-of-service time resulting from components being in Condition A of this SLC and routine calibration/servicing time.
