The Peach Bottom nuclear plant in Pennsylvania gained permission for its two reactors to each generate an additional 140 megawatts of electricity, federal regulators said.

Exelon applied for a 12.4 percent extended power uprate for units 2 and 3 in the fall of 2012. (Peach Bottom unit 1 was a smaller gas-cooled reactor shut down in 1974).

Plans call for improvements to increase each unit’s power by 437 megawatts-thermal. A release from the Nuclear Regulatory Commission (NRC) reported Exelon plans to increase the power at unit 4 during a refueling outage this fall and at unit 3 during its refueling outage a year later.

The reactors near Lancaster, PA, entered service in 1973 and 1974. Both are General Electric type 4 boiling water reactors with Mark I containment.

NRC records indicate the reactors gained approval for a 5 percent uprate in the mid-1990s and a 1.62 percent uprate in 2002.
