PHONE CALL FROM DUKE POWER COMPANY, OCONEE, DOCKET NOS. 50-269, 50-270, AND 50-287 Messrs P. Barton and C. Dewey called on September 3 to indicate status on additional meteorological studies underway at Duke.
Mr. Dewey said that he was not as far along as expected and that he was still working on inversion tables and compiling information on inversions by thermo-graphic data. Also, they were compiling information on the 4 months of coincidence tower /near-ground data.
They have two primary objectives they hope to realize from this work (1) prove or disprove usage of the thermographs (Mr. Dewey considers the tower data very reliable) and (2) to obtain a full month of coincident pole data classified by tower stability data.
They expect to prepare a matrix of wind speed vs inversion strengths under poor diffusion conditions.
If this data does not look encouraging, they will then review data for each hour studying the charts for X/Q.
In the area of additional testing they have scheduled smoke tests around the reac-tor location during nighttime conditions, probably Wednesday, Thursday, and Friday of next week (subject, of course, to meaningful weather conditions).
Mr. Dewey also indicated that they have purchased an M.R.I. weather station from Pasadena having capabilities of accurate measurement of wind speeds in the range of 0.2 to 0.8 miles per hour. This M.R.I. weather station is first going.to be located down in the valley between the station and the river on low ground.
During *the smoke tests they plan to release on the order of one-half million cubic feet of smoke, plan to have photographers on hand, and also men stationed down the valley, near the intake structure and also back up the lake at the interconnecting canal area.
During this period of time they will be taking full data from the tower and from the new M.R.I. station.
Mr. Dewey estimated that by the end of next week, September 11 or 12, they would like to report progress to us.
He will set this up by phone call some time on Thursday, September 11.
