We have concluded that the provisions for preventing continuous control rod withdrawal during operation are sufficient to assure that withdrawal rates under all conditions will not result in excessive reactivity insertion. The typical time required to withdraw a control rod one notch is between 4 and 8 seconds and complete withdrawal requires withdrawing 23 notches.

Therefore we have also concluded that a control rod can not be withdrawn in less than 23 seconds in tt.e notch mode.

Based on the above considerations, we have concluded that the require-ments for control rod withdrawal test every six months during power operation may be deleted.

'r'e therefore conclude that the proposed changes to the Tecnnical Specifications are acceptable.

Environmental Considerations Me have determined that the amendment does not authorize a change in effluent types or total amounts nor an increase in power level and will not result 'n any significant environmental impact. Having made this determination, we have further concluded that the amendment in"olves an action which is ir.significant from the standpoint of environmental impact and pursuant to 10 CFR 551.5(d)(4) that an environmental impact statement or negative declaration and environ-inntal impact appraisal need not be prepared in connection with the issuance of this amendment.

Conclusions We have concluded, based on the considerations discussed above, that:

(1) because the amendment does not involve a significant increase in the probability or consequences of accidents previously considered and does not involve a significant decrease in a safety margin, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the health and safety of the public will not be erdangered by operation in the proposed manner, and (3) su:h activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
