letter. The needed additional information relates to your onsite J
netcorolog'. cal measurements program described in the FSAR (Section 2.3) 4" i
which you are using as the basis in support of several proposed sections i
in the new format Technical Specifications.
3 You should file your response to this request for additional information in the usual manner as an amendment to your application.

REQUEST FOR ADDITIONAL INFORMATION YANKEE NUCLEAR POWER STATION (YANKEE-ROWE)
DOCKET NO. 50-29 FSAR, SECTION 2.3 METEOROLOGY r
1.
You evaluated the site meteorology using data collected during
~
the period October, 1971 through September 1972 and you provided
[
summaries of the data in Section 2.3 of the FSAR.
In order for g
us to determino if the dispersion factors computed by you reflect
~,
the average meteorology for the Yankee-Rowe site, provide onsite meteorological data with at least 90% data recovery that cover at least two annual cycles including calm wind class and data recovery rate. Also, provide monthly wind roses.
2.
In order for us to determine if the proximity of the meteorological tower (500 feet) to the containment introduces a wake effect that may influence realistic wind representation, provide a site plan showing the location of the containment sphere and the position of the new meteorological tower.
3.
Provide a description of the maintenance and calibration procedures for the acteorological equipment in sufficient detail to show that the equipment is adequately inspected and serviced at a frequency that will assure at least 90% valid data recovery.
