o 3/4.9 REFUELING OPERATIONS 3/4.9.1 BORON CONCENTRATION LIMITING CONDITION FOR OPERATION l
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 restnctive of the reactivity conditions specified in the COLR is met.
i APPLICABILITY: MODE 6*.
ACTION With the requirements of the above specification not satisfed, immediately suspend all operations involving CORE ALTERATIONS or positive res@vity changes and initiate action to restore boron concentration to within COLR limits.
SURVEILLANCE REQUIREMENTS 4.9.1.1 The more restnctive of the above two reactivity conditions shall be determined prior to:
1 a.
Removing or unbotting the reactor vessel head, and b.
Withdrawal of any full 4ength CEA in excess of 3 feet from its fully inserted I
position within the reactor pressure vessel.
l 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 reactor vessel head closure botts less than fully tensioned or with the head removed.
