We normally manually trip the reactor between 15 and 20%, will likely be lower since we uprated by more than 8% this cycle. When we shutdown for Hurricane Katrina, we tripped the reactor and turbine at about 10%.

Fort Calhoun is considering performing a manual reactor trip at 20% power (Turbine Trip is actually at 15%) when coming down for our fall outage... This would save us approximately 2 to 4 hours of critical path.
If you currently perform (or can perform) this type of technique or have/had experience with this, please provide me a point of contact or any related information or opinions.
Thank you in advance,
