PLANT SYSTEMS BASES 3/4.7.13 GROUN0 WATER LEVEL This specification is provided to ensure that groundwater levels will be monitored and prevented from rising to excessively high levels which could cause unacceptable structural stresses in the reactor containment and/or auxiliary building due to uplift forces.

Structural stresses due to high groundwater levels will not exceed allowable stresses until groundwater rises to elevation 732 MSL.

3/4.7.13 STAN08Y SHUTDOWN SYSTEM The OPERABILITY of the SSS ensures that a fire will not preclude achieving safe shutdown.

The SSS equipment are independent of areas where a fire could damage systems normally used to shutdown the reactor.

This capability is consistent with GDC 3 and 10CFR50, Appendix R.

The equivalent shutdown capability provided when the SSS is inoperable depends on the specific equipment involved and, therefore, should be sufficient to assure that the intended shutdown actions can be accomplished, or that fires can be reasonably precluded during that time for which SSS equipment would otherwise be required, consistent with the SSS design basis. Any temporary procedures or special fire watch patrols established to provide this equivalent capability shall be reviewed and approved prior to implementation in accordance with Section 6.0 of Technical Specification.
