I Itmiting F i tilt of 1.025 can be tolerated before the margin for uncertainty in g s depleted. The limit of 1.02 was selected to provide an allowance for the uncertainty associated with the indicated power tilt.

The two hour time allowance for operation with a tilt condition greater than 1.02 but less than 1.09 is provided to a11ow identification and correction of a cropped or misaligned contre) rod. in the event such action does not correct the tilt, the margin for uncertainty on F isgreinstated by reducing the maximum allowed power by 3 percent for each percent of tilt in excess of 1.0, For purposes of monitoring QUADRANT POWER TILT RATIO when one encore detector is inoperable the movable incere detectors are used to confirs that '

the normalized symmetric power distribution is consistent with the QUADRANT POWER TILT RATIO. The incore detector monitoring is done with a full incere flux map or two sets of 4 symmetric thinoles. These locations are C 8. E 5 E-11, H 3, H-13. L 5, L 11, N-8. +
