. Att:chment to AECM-82/597 Page 7 of 8 Docket No. 50-416 Date 12/15/82 Completed by: J. D. Richardson Telephone: 601-969-2630 OPERATING DATA REPORT SUPPLEMENTAL INFORMATION A temporary modification, following a 10CFR50.59 evaluation, was made on November 2, 1982 to allow bypassing the Containment Cooling Ventilation Exhaust System while maintenance activities were performed in the suppression pool. The following information is submitted pursuant to the requirements of Technical Specification 6.15.1:

6.15.1

a. An evaluation was conducted and a determination was made in conformance with 10CFR50.59, that the temporary bypassing of the Containment Cooling Ventilation Exhaust System did not involve an unreviewed safety question or Technical Specification change. This determination was based upon the present plant operational condition (cold shutdown) and the fact that no appreciable fission product inventory is present. The modification was determined to not involve an increase in the probability of an ' occurrence or the consequences of an accident previously considered in the FSAR and does not involve a significant decrease in the safety margin.

No changes to Technical Specifications were determined to exist in that primary and secondary containment integrity was not required per Technical Specifications 3.6.1.1 and 3.6.6.1 for Operational Condition 4. During this period, the function of gaseous effluent monitoring, required by Technical Specification 3.3.7.12, was accomplished by portable sampling systems,

b. The reason for the temporary modification was to bypass the Containment Cooling Ventilation Exhaust System to reduce sandblasting dust concentrations and painting fumes from maintenance activities in the suppression pool area. The passing of this dust and fumes through the containment cooling filter trains of the permanent plant equipment could damage the filter trains and associated equipment.
c. The temporary modification consisted of the use of temporary exhaust fans taking a suction from the area of the suppression pool and discharging through ventilation hoses directly to the environment.
d. No exhaust gases with radiation significantly above background, as measured by portable monitoring instrumentation, were discharged.

The releases were negligible and within the limits addressed in the FSAR.

e. Since non-radioactive gases were diccharged, there were no significant changes in expected maximum exposures to individuals in unrestricted areas, nor significant differences from exposures previously calculated in the FSAR.
f. Since no prior release data of significant quantities is available, this non-radioactive discharge cannot be meaningfully compared.
g. The change in exposure to plant operating personnel will be negligible, since no gases with radioactivity significantly above background radiation were discharged.
h. The documentation of the PSRC review is addressed in the PSRC meeting notes and the 10CFR50.59 evaluation form.
