1. With K greater than or equal to 1.

1. 1. A reacfN power cutback will cause either (Case 1) Regulating Group 5 or I

Regulating Group 4 and 5 to be dropped with no sequential insertion of additional Regulating Groups (Groups 1, 2, 3, and 4) or (Case 2) Regulating Group 5 or Regulating Groups 4 and 5 to be dropped with all or part of the remaining Regulating Groups (Groups 1, 2, 3, and 4) being sequentially inserted.

In'either case, the Transient Insertion Limit and the withdrawal sequence of Figure 3.1-3 or Figure 3.1-4 can be exceeded for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
