ADMINISTRATIVE CONTROLS ANNUAL REPORTS (Continued) 6.9.1.5 Reports required on an annual basis shall include: -

a. A tabulation on an annual basis of the number of plant, utility, and 1 other personnel (including contractors) receiving exposures greater than 100 mrems/yr and their associated man-rem exposure according to work and job functions,* (e.g. , reactor operations and surveillance, inservice inspection, routine maintenance, special maintenance

[ describe maintenance), waste processing, and refueling). The dose assignments to various duty functions may be estimated based on pocket or thermoluminescent dosimeters (TLD) dosimeters or film badge measurements. Small exposures totalling less than 20% of the indi-vidual total dose need not be accounted for. In the aggregate, at least 80% of the total whole-body dose received from external sources should be assigned to specific major work functions; and

b. Documentation of all challenges to main steam line safety / relief valves, and l

A summary of ECCS outage data including:

c.

i Add 1. ECCS outage dates and duration of cutages, Cause of each ECCS outage, 2.

3. ECCS systems and components in the outage, and

6.9.1.6 Routine reports of operating statistics and shutdown experience shall be submitted on a monthly basis to the Director, Office of Resource Management, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555, with a copy to the Regional Administrator of the Regional Office of the NRC, no later than the 15th of each month following the calendar month covered by the report.

i ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT **

6.9.1.7 Routine Annual Radiological Environmental Operating Reports covering l the operation of the unit during the previous calendar year shall be submitted l prior to May 1 of each year. The initial report shall be submitted prior to May 1 of the year following initial criticality. ,

The Annual Radiological Environmental Operating Reports shall include summaries, j interpretations, and an analysis of trends of the results of the radiological environmental surveillance activities for the report period, including a compar-l ison as appropriate, with preoperational studies, with operational controls, and with previous environmental surveillance reports, and an assessment of'the observed impacts of the plant operation on the environment. The reports shall also include the results of land use censuses required by Specification 3.12.2.  ;

1 The Annual Radiological Environmental Operating Reports shall include the results of analysis of all radiological environmental samples and of all environmental l ,

t l *This tabulation' supplements the requirements of $20.407 of 10 CFR.'Part 20.

A2-3 VP-86-0028 Insert 2 The reports shall also include the results of specific activity analysis in which the primary coolant exceeded the limits of Specification 3.4.5. 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 and one other radioiodine isotope concentrations 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 radioiodine limit.

REACTOR COOLANT SYSTEM BASES 3/4.4.5 SPECIFIC ACTIVITY The limitations on the specific activity of the primary coolant ensure that the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> thyroid and whole body doses resulting from a main steam line failure outside the containment during steady state operation will not exceed small fractions of the dose guidelines of 10 CFR 100. The values for the limits on specific activity represent interim limits based upon a parametric evaluation by the NRC of typical site locations. These values are conservative in that specific site parameters, such as site boundary location and meteorological conditions, were not considered in this evaluation.

Information obtained on iodine spiking will be used to assess the parameters associated with spiking phenomena. A reduction in frequency of j

isotopic analysis following power changes may be permissible if justified by the data obtained.

Closing the main steam line isolation valves prevents the release of activity to the environs should a steam line rupture occur outside containment.

The surveillance requirements provide adequate assurance that excessive specific e activity levels in the reactor coolant will be detected in sufficient time to take corrective action.
