LIMITING CONDITIONS FOR OPERATION 3.1.3 CONTROL ASSEMBLIES MECHANISM (ENERGIZATION) 3.1. 3.1 All control rod drive mechanisms shall be deenergized except that one mechanism at a time may be energized as allowed by procedure (s) approved by the NRC staff in accordance with Technical Specification 6.8.2.
APPLICABILITY: When fuel is in the reactor pressure vessel.
i ACTION:
None except as provided in Specification 3.0.3.

O 3/4.1 WATER INJECTION COOLING AND REACTIVITY CONTROL SYSTEMS BASES 3/4.1.1 BORATION CONTROL The limitation on minimum boron concentration ensures that the core will remain subcritical under all possible conditions which may exist during the long-term cooling mode.
The maximum boron concentration is provided to ensure that precipitation of boron will not occur in the reactor coolant system and thereby cause possible flow restrictions.
The specification requiring the OPERABILITY of two systems capable of injecting borated cooling water into the Reactor Coolant system are provided to ensure that makeup water can be injected into the reactor coolant system and that the reactor coolant will be maintained within the required boron concentration limits.
The required volume of borated water in the BWST provides sufficient water to cool the core via low pressure injection for at least three days, during which time alternate cooling means could be provided.
3/4.1.3 CONTROL ASSEMBLIES Normally maintaining the control rod drive mechanisms deenergized provides assurance that the rods will not be inadvertently withdrawn.
Preparation of specific procedure (s) to allow energizing individual mechanisms and obtaining NRC approvals ensures sufficient evaluation and ettention has been paid to assure the health and safety of the public.
