Please respond to PWR Reactivity Management pwrrm@retaqs.com
Two Questions involving standard ramp plans (the plans given to ops for common ramping needs- turbine balance shot, misaligned rod, backing off RTP, securing MFP):
How many cases are run for the standard ramp plans given to ops? (our sites run between six per month per unit to 16 per quarter)
How often are standard ramp plans updated at each site? (we do monthly for two of our sites, quarterly at the other two)
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.
