l.
Restored to OPERABLE status within its above specified alignment requirements, or 2.

- 3. 1.3.6 and 3. 1.3.7 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(s) shall be aligned to within 6.6 inches of the inoperable CEA(s) while maintaining the allowable CEA sequence and insertion limits shown on Figures
- 3. 1-3 and
- 3. 1-4; the THERMAL POWER level shall be restricted pur-suant to Specifications
- 3. 1.3.6 and 3. 1.3.7 during subse-quent operation.
