REACTIVITY CONTROL SYSTEMS 3/4'.1. 3 MOVABLE CONTROL ASSEMBLIES CEA POSITION-LIMITING CONDITION FOR OPERATION 3.1.3.1 CEAs which are inserted in the core, shall be OPERABLE with given group positioned within 7 inches (indicated position) of all other CEAs in 'ts group.
APPLICABILITY:
H0 DES 1* and 2*.
ACTION:
With one or more full-length CEAs inoperable due to being innovable a.
as a result of excessive friction or mechanical interference or known to be untrippable, determine that the SHUTDOWN MARGIN require-ment of Specification 3.1.1.1 is satisfied within I hour and be in at least HOT STANDBY within 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />.
b.
With more than one full-length or part-h ngth CEA inoperable or misaligned from any other CEA in its group by more than 19 inches (indicated position), be in at least. HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
With one full-length or part-length CEA misa11gned from any other c.
CEA in its group by more than 19 inches, operation in H0 DES 1 and 2 may continue, provided that core power is reduced in accordance with Figure 3.1-1A and that within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> the misaligned CEA is either:
1.
Restored to OPERABLE status within its above specified alignment requirements, or 2.
Declared inoperable and the SHUTDOWN MARGIN requirement of Specification 3.1.1.1 is satisfied.
After declaring the CEA--
inoperable, operation in MODES 1 and 2 may continue pursuant to the requirements of Specification 3.1.3.6 provided:
a)
Within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> the remainder of the CEAs in the group with the inoperable CEA shall be aligned to within-7 inches of the inoperable CEA while maintaining the allowable CEA sequence and insertion limits shown on Figure 3.1-2; the THERMAL POWER level shall be restricted pursuant to Specification 3.1.3.6 during subsequent operation.
b)
The SHUTDOWN MARGIN requirement of Specification 3.1.1.1 is determined at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
Otherwise, be in at least HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
