Breaker-to-Breaker Runs 2 runs
Breaker-to-breaker runs measure continuous operation between refueling outages using a cycle-adjusted threshold (90% of cycle length minus RFO duration). An active streak means the unit has been running continuously since the last refueling with no trips to 0% power.
Palisades has logged 2 breaker-to-breaker runs, continuous stretches from one refueling to the next with no trip to zero power. Its longest ran 577 days, and its runs average 512 days.
