Big Rock Point Nuclear Power Plant
Big Rock Point was a nuclear power plant near Charlevoix, Michigan, United States. Big Rock operated from 1962 to 1997. It was owned and operated by Consumers Power, now known as Consumers Energy. Its boiling water reactor was made by General Electric (GE) and was capable of producing 67 megawatts of electricity. Bechtel Corporation was the primary contractor.
Big Rock was Michigan's first nuclear power plant and the nation's fifth. It also produced cobalt-60 for the medical industry from 1971 to 1982.
Ground was broken on July 20, 1960. Construction was completed in 29 months at a cost of $27.7 million. Its license from the Nuclear Regulatory Commission was issued on August 29, 1962. The reactor first went critical on September 27 and the first electricity was generated on December 8, 1962.
A promotional video for the plant featured then GE spokesman Ronald Reagan.
Consumers Energy had previously announced that Big Rock Point's operating license would not be renewed when it expired on May 31, 2000. However, economics proved in January 1997 that it was not feasible to keep Big Rock Point running to the license's expiration date.
The reactor was scrammed for the last time at 10:33 a.m. EDT on August 29, 1997, 35 years to the day after its license had been issued. The last fuel was removed from the core on September 20. Decontamination was completed in 1999.
During the decommissioning process it was discovered that a backup safety system at the plant had been inoperable for at least the previous 14 years. The Liquid Poison System (LPS) consisted of a tank filled with a liquid solution containing boron, a neutron absorber. In the event of a control rod failure during a reactor scram, the LPS system would have drained the boron solution into the core thus halting the nuclear chain reaction. However, during decommissioning when technicians attempted to drain the tank they were unable to do so due to a corroded pipe.
Because of its contributions to the nuclear and medical industries, the American Nuclear Society named Big Rock Point a Nuclear Historic Landmark.
