a ANNUAL REPORT
, 5.9.1.3 Annual Reports covering activities as described below for the previous l calendar year shallinclude:
A. A tabulation on an annual basis of the number of station, utility and eihor personnel (including contractors) receiving exposures greater than 100 mrem /yr and their associated man rem exposure l
according to work and job functions,
- e.g., reactor operations and surveillance, inservice inspection, routine maintenance, special l
maintenance (describe maintenance), waste processing, and refutiling.
The dose assignment to various duty functions may be estimates beced on pocket dosimeter, TLD, or film badge measurements.
Small exposures totaling less than 20% of the individual total dose l
need not be accounted for. In the aggregate, at least 80% of the total whole body dose received from extemal sources shall be l assigned to specific major work functions.
- This tabulation supplements the requirement of Section 20.407 of 10 CFR Part 20.
Response: Attached please find a table," Maine Yankee Atomic Power Company Reg. Guide 1.16, Man-Rem Final End of the Year Report for 1996".

ANNUAL REPORT 5.9.1.3 B. The results of specific activity analysis in which the primary coolant exceeded the limits of Specification 3.2. The following information shall be included: (1) Reactor power history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior
! to the first sample in which the limit was exceeded; (2) Results of the last isotopic analysis for radiciodine performed prior to exceeding the limit, results of analysis while limit was exceeded and results of one analysis after the radioiodine activity was reduced to less than limit. Each result should include date and time of sampling and the radioiodine concentrations; (3) Clean-up system flow history starting 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to the first sample in which the limit was exceeded; (4) Graph of the I-131 concentration and one other radiciodine isotope concentration in microcuries per gram as a function of time for the duration of the specific activity above the steady-state level; and (5) The time duration when the specific activity of the primary coolant exceeded the radiciodine limit.
