Active reactors ( gross ):

The nuclear power plant Byron (English Byron Nuclear Generating Station ) is a nuclear power plant in Byron, Rockford in Ogle County in northern Illinois in the U.S., about 90 kilometers west of Chicago. The nuclear power plant, which consists of two pressurized water reactors, has a total capacity of 2,421 MW. The owner and operator is the Exelon Generation. It provides power to the northern part of the State of Illinois and for the city of Chicago.

Reactors

The nuclear power plant Byron consists of two pressurized water reactors Byron and Byron -1 -2. Construction of both reactors was on 31 December 1975. The first block was for the first time critically on February 2, 1985, the second on January 9, 1987. On March 1, 1985, Byron -1 first synchronized to the power grid and is since September 16, 1985 commercial operation. The first network synchronization of the reactor Byron -2 took place on 6 February 1987, after more than eleven years of construction time he went into commercial operation on 21 August 1987. As things stand, to Byron -1 in 2024 be shut down in 2026 to Byron -2 follow. The reactors were supplied by Westinghouse. The reactors cost around 4.5 billion U.S. dollars. The produced in nuclear power plant electricity sufficient to power two million average U.S. houses with electricity. In the plant, about 690 employees of Exelon work. Exelon pays annual property taxes of 28 million U.S. dollars.

Performance

The net electrical output of the reactor Byron -1 is 1164 MW, 1225 MW gross capacity. Byron - 2 has a net output of 1136 MW and a gross capacity of 1196 MW.

Cooling

The nuclear power plant has two natural draft wet cooling towers with a height of 495 feet each. The nearby Rock River is taken from cooling water for cooling the reactors.

Security

After the terrorist attacks on 11 September 2001, the safety devices have been greatly exacerbated by the power plant. To the power plant, there is a so-called security zone that can not be built on.

Since February 2006, Exelon is working with the Illinois EPA to investigate tritium contamination in groundwater.

On 19 October 2007 there was a leak in a cooling water pipe in the non-nuclear part of the plant that was discovered during a patrol. This was the first time since the mid -1990s that both blocks were simultaneously inoperative. On 31 October 2007 the reactors went into operation again.

On 30 January 2012, probably due to a defect of a component of a substation to power the reactor, tritium off steam. The reactor was shut down and powered by diesel generators with power, assessed the incident by the U.S. Nuclear Regulatory Commission as " unusual event ," the lowest of the four levels of danger.
