Mr. Greg Yuhas
Dear Sir:
Subject:
Docket Nos. 50-206, 50-361 and 50-362 Magnetic Tapes of SONGS Meteorological Data for January 1, 1984 to December 31, 1984 San Onofre Nuclear Generating Station, Units 1, 2 and 3 In accordance with your [arch 5, 1985 telephone discussion with Mr. K. S. Helm of the Chemistry Department, enclosed are the requested magnetic tapes containing the final SONGS meteorological data for 1984.
You requested these tapes in order that they can be used by the NRC staff in Washington in an intercomparison study between several plants.
These tapes (#379 and 593) are written in standard ANSI Level 3 format with one file on each tape. They are labeled 9-track, 1600 bpi magnetic tapes written in ASCII. Each file on the tapes is blocked 4000 characters with each record 80 characters in length.
The format of the data contained in each file is presented in Enclosure.1.
When you have completed your study and no longer require use of these tapes we request that they be returned to our Compliance Division. They can be sent Attention: P. A. Croy.
If you require any additional information, please so advise.
