Operations has requested and Reactor Engineering provides, at the
beginning of each cycle, reactivity plans for the following scenarios: 100% to
55% over one hour, 100% to 55% over four hours, 100% to 17% over four hours,
and 100% to 17% over five hours. A set of plans is provided at 1 GWd/MT
intervals for the entire cycle. These plans are based on design data
provided by the vendor model in the NuPOP. Cook does not have an online
core model, so updating the plans would have no effect; they are all provided
at BOC.
