y Oconee Nuclear Station Technical Specification 3.6 requires containment integrity be maintained when all three of the following conditions exist:
1.
Reactor coolant pressure is 300 psig or greater 2.
Reactor coolant temperature is 200 F or greater 3.
Nuclear fuel is in the core Containment integrity is defined by Section 1.7 of the Technical Specifi-cations.
It is required that both doors of the personnel hatch and emergency hatch be closed and sealed except that at least one door of the personnel hatch and the emergency hatch must be closed and sealed during refueling or during personnel passage through these hatches.
There are no provisions under the current definition which permit preventative or corrective maintenance to be performed on one of these doors when containment integrity must exist.
Pursuant to 10CFR 50.59, it is requested that Section 1.7 of the Oconee Nuclear Station Technical Specifications be revised such that maintenance on one door of either the personnel or emergency hatch is permitted for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> provided the reraining door is closed and sealed.
This proposed change ir shown on the attached replacement page for the Oconee Technical Specifica tions.
A maintenance period of up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is considered acceptable since the other door will be kept closed and sealed.
Containment integrity is not impaired since either door meets the design specifications for structural integrity and leak rate.
The period of 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is requested 8042
