This data is presented on page 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 rcport of the total number of individuals for whom personnel monitoring was provided for the reporting year. This number and a statistical summary of whole i body exposure to these individuals is presented on page four of this attachment. An explanation of the statistics is provided on page five of this attachment.

i k-Attachment i l ST-HL-AE-4020 Page 5 of-5 ANNUAL PERSONNEL EXPOSURE REPORTS The difference in total man-rem recorded on these two reports is due to the use of TLD values on the 10CFR20.407 report and use of SRD values on the Technical Specification 6.9.1.2.a report.

Single individuals are listed in more than one work category on the Technical Specification 6.9.1.2.a report. This accounts for the apparent discrepuncy in the number of individuals with a whole body exposure greater tiG 7 100 mrem on the 10CFR20.407 report.
