Breaker-to-Breaker Runs 8 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.
Point Beach 1 has logged 8 breaker-to-breaker runs, continuous stretches from one refueling to the next with no trip to zero power. Its longest ran 550 days, and its runs average 511 days.

About This Site
Written by NukeWorker from public records: facts that do not change. Operator, status and capacity come from the live data elsewhere on this page. Sources: Wikipedia: Point Beach Nuclear Plant.
Point Beach Nuclear Plant sits on the western shore of Lake Michigan in the Town of Two Creeks, Manitowoc County, Wisconsin, near the city of Two Rivers.

Wisconsin Electric Power Company built the plant, with a groundbreaking on November 28, 1966. It has two Westinghouse two-loop pressurized water reactors. Construction of Unit 1 began in July 1967 and Unit 2 in July 1968. Unit 1 reached initial criticality on November 2, 1970, and entered commercial operation on December 21, 1970. Unit 2 followed in 1972, with commercial operation dated October 1, 1972. Steam generator degradation held Unit 1 to reduced power from December 1979 until replacement steam generators were installed in October 1983. Unit 2's steam generators were replaced in 1996 and 1997.
