Dear Mr. Groce:
RE:
COMPLETION OF SEP TOPIC II-2.8 - YANKEE R0WE Your letter dated June 25, 1979, indicated that you have examined our draft evaluation of the subject topic dated May 29, 1979.
You suggested editorial or corrective changes to the assessment to make it more accurately reflect your facility design. We have incorporated your suggested modifications in the enclosed assessment. With these modifications our review of SEP Topic II-2.8 is complete anc will be a basic input to the integrated assessment of your facility.
The subject assessment compares your facility design with the criteria currently used by the staff in licensing new facilities. This assessment may need to be re-examined if you modify your facility or if the criteria are changed before we complete our integrated assessment.
Sincerely, y
Mi

Complete - November 15, 1979 SYSTEMATIC EVALUATION PROGRAM METEOROLOGY YANKEE R0WE Topic II-2.B Onsite Meteorological Measurements Program The safety objective of this review is to assure that adequate meteorological data are available to quantify poten N. 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 33, 195 Dry bulb temperature 33 Vertical temperature gradient 33 to 195 Precipitation, solar radiation Near Ground Level The data are ecorded on a floppy disk with analog strip charts provided as backup. All the recording equipment located inside the control room. The recorders will provide a reco, of the meteorological conditions following any accidental releases as well as for routine releases during plant operation.
I799 9b
. 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.
