l 3/4.9.1 BORON CONCENTRATION

= LIMITING CONDITION FOR OPERATION-3.9.1 With the reactor, vessel head closure bolts less-than fully tensioned or-

-with the head removed, the boron concentration of all filled portions of the Reactor Coolant System-and the refueling canal shall be maintained uniform and sufficient to ensure that the more restrictive of the following reactivity conditions is met:

Either a K,ff of 0.95 or less, which includes a 1% delta k/k conser a.

vative allowance for uncertainties, or b.

A boron concentration of greater than or equal to 2000 ppm, which includes a 50 ppm conservative allowance for uncertainties.

APPLICABILITY:

MODE 6*

ACTION:

With the requirements of the above specification not satisfied, immediately

.. suspend all operations involving CORE ALTERATIONS or positive reactivity changes and initiate and continue boration at greater than or equal to 10 gpm of a solution containing greater than or equal to 20,000 ppm boron or its equivalent until Keff is reduced to less than or equal to 0.95 or the boron concentration is restored to greater than or equal to 2000 ppm, whichever is the more restrictive.

The provisions of Specification 3.0.3 are not applicable.

SURVEILLANCE REQUIREMENTS

4. 9.1.1 The more restrictive of the above two reactivity conditions shall be determined prior to:

a.

Removing or unbolting the reactor vessel head, and b.

Withdrawal of any full length control rod in excess of 3 feet from its fully inserted position within the reactor pressure vessel.

4.9.1,2 The boron concentration of the reactor coolant system and the refueling canal shall be determined by chemical analysis at least once per 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

• The reactor shall be maintained in MODE 6 whenever fuel is in the reactor vessel with the vessel head closure bolts less than fully tensioned or with the head removed.
