Attachment 1 ST.HL-AE-3700 Page 1 of 5 ANNUAL PERSONNEL EXPOSURE REPORTS Technical Specification 6.9.1.2a reqaires a tabulation on an annual basis of the number of station, utility, and other personnel (including contractors) receiving exposures greater than 100 mrom/yr and their associated man rem exposures according to work and job functions. This data is presented on pago two of this attachment. Specific tasks included in the Special Maintenance work and job function are listed on page three.

10CFR20.407(a) requires a report of the cotal number of individuals for whom personnel monitoring was provided for che reporting year. This number and a statistical summary of whole body exposure to these individuals is ll presented on page four of this attachment. An explanation of the statistics is provided on page five of this attachment.

During 1990, 2840 personnel were monitored and no single individual received greater than 2.0 rem. A majority of the dose,193 rem, was roccived during planned refueling outages performed in each Unit. The increase in the 1990 total man rem when compared 1989 is primarily due to the two refueling outages perforced in 1990 versus one in 1989.
