SYSTEMATIC EVALVATICA PROGRAM METEOROLOG*

YANKEE R0WE Topic II-2.8 Onsite Meteorological Measurements Program The safety objective of this review is to assure that adequate meteorological data are available to quantify potential offsite exposures from routine and accident releases of radioactive products.

The operational meteorological measurements program for Yankee Rowe consists of a 200 foot free standing tower located approximately 600 feet north of the reactor containment. Listed below are the instrumentation and the heights of measurement on the tower.

Measured Parameter Elevation Above Ground (Feet)

Wind direction and speed 32, 196 Ory bulb temperature 32 Vertical temperature gradient 32 to 196 Precipitation, solar radiation Near Ground Level The data are recorded on magnetic tape with analog strip charts provided as backup. All the recording equipment is located inside the control room. The recorders will provide a record of the meteorological conditions following any accidental releases as well as for routine releases during plant operation.

2307 126

. Based on examination of the measurements system, which conforms to the position stated in Regulatory Guide 1.23 for system accuracies, the meteorological data collected at the onsite tower provide adequate meteorological data for assessments of meteorological conditions in the vicinity of the site for routine and accidental releases.

Therefore, we conclude that the onsite meteorological measurements program provides the licensee with adequate meteorological data to quantify offsite exposures from routine and accidental releases.

This completes the evaluation of this SEP topic. Since the plant design conforms to current licensing criteria, no additional SEE review is required.
