1 significantly different from those resulting from operation within the target band. The instantaneous consequences of being outside the band, provided rod insertion-limits are observed, is not worse than a-10 percent increment.in l peaking factor.for flux difference in the range 1 (y + 3) percent (t y percent to
.4 percent indicated) increasing by 1 1 percent for each 2 i
percent decrease in rated power. Therefore, while the deviation exists the power level is limited to 90% of PT or lower _ depending on the indicated flux difference.
If, for any reason, flux difference is not controlled within the AI target band for as long a period as one hour, then xenon distribution may i
be significantly changed and operation at 50 percent is required to protect-against.potentially more severe consequences of.some accidents.
As discussed above, the essence of the procedure is to maintain the xenon distribution in the core i
as close to the equilibrium full power condition as possible. This is accomplished by.using the boron system to position the full length control rods to produce.the required indicated flux difference.

For Condition 11 events, the core is protected g
from overpower and a minimum DNBR of the applicable design limit DNBR by an automatic r+

procedures is assumed as a precondition for Condition 11 transients; however, operator error o,
