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)
BEACON is used to generate six standard cases.. Ramp to 15% power in 7 hours. Ramp to 15% power in 2 hours. Rapid power reduction to 90%, 70%, 50% and 30%.
Specific ramp plans are generated for planned ramps.
How often are standard ramp plans updated at each site? (we do monthly for two of our sites, quarterly at the other two)
Standard ramp plans are valid for 2,000 MWD/MTU (about 48 days).
