3/4.9 REFUELING OPERATIONS i

}/4.9.1 BORON CONCENTRATION ijk MING CONDITION FOR OPERATION 3.9.1 The boron concentration of all filled portions of the Reactor Coolant  :

System and the refueling canal shall be ;aaintained uniform and sufficient to -

ensure that the more restrictive of the following reactivity conditions is met: ,

a. Either a K,ff of 0.95 or less, or  ;

b. A boron concentration of greater than or equal to 2000 ppm.

APPLICABILITY: MODE 6*, with the reactor vessel head closure bolts less than I fully tensioned or with the head removed. -

ACTION:

With the requirements of the above specification net satisfied, immediately suspend all operations involving CORE ALTERATIONS or positive reactivity changes and initiate and continue boration at greater than or equal to 30 gpm ,

of"a so'1ution containing greater than or equal to 7000 ppm boron or its equivalent until K is reduced to less than or equal to 0.95 or the boron i concentrationisrINoredtogreaterthanorequalto2000 ppm,whicheveris the more restrictive.

SURVEILLANCE REQUIREMEMT; 4.9.1.1 The more restrictive of the above two reactivity conditions shall be determined prior to:

a. Removing or vnbniting 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 vessel.

[ 4'. 9.1. 2 The boron concentration of the Reactor Ccolant System and the

', refueling canal shall be determined by chemical malysis at least noce per y .72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
