The Susquehanna nuclear power plant ( English Susquehanna Steam Electric Station (SSES) ) is located on the Susquehanna River in Luzerne County in the state of Pennsylvania in the United States.

history

The power plant from 1970 was planned on November 2, 1973, the start of construction of the two was made General Electric - boiling water reactors of type BWR-4 Mark 2. Identical reactors are among others in the Limerick Generating Station . The first unit became critical on September 1, 1982, and started operations on November 16, 1982. From June 8, 1983, the block began to feed electricity into the public power grid. Unit 2 became critical for the first time on May 8, 1984 and started operations on July 3, 1984. Unit 2 went into commercial operation on February 12, 1985. The power plant cost over $ 4.1 billion. The operating license for Unit 1 will expire in 2022 and that of Unit 2 in 2024.

Originally the reactors had an output of 1,100 megawatts. The steam has a temperature of 280 ° C and the turbines of the reactors are 63 meters long. The reactors are two boiling water reactors with a coolant flow rate in excess of 817 m³ per minute (216,000  gallons per minute). The fuel elements in the reactor are enriched from 0.71% to 4.95%. The fuel tablets are in tubes made of zircalloy . The system's cooling towers are 164 meters high.

In 2003 and 2004 the turbines of the plant were modernized. The reason was that more and more cracks appeared in this part of the system. The modernization made it possible to produce 80 megawatts more power, so that the reactors could be shut down by 50 megawatts, whereby the material was spared and the burnup was somewhat reduced. Replacing the turbine required the reactors to be shut down for 38 days. There is also a plan to increase the thermal output of the reactors by 13%. A further modernization of the turbine was to be carried out in 2007 and 2008.

In addition to the nuclear power plant, a new nuclear power plant called Bell Bend and a US EPR (Evolutionary Power Reactor) was to be built. All licenses for the building should be obtained by the end of 2008. In March 2015 Areva announced that it would pursue a new business strategy. This does not involve building new reactors.

Disruptions

• On September 10, 2003, both reactors had to be shut down slightly because of an oil fire. The fire broke out on one of the circulation pumps in Unit 1.
• On April 28, 2005, Unit 2 had to be taken off the grid because there was a problem with a transformer.
• On June 6, 2005 at 12:33 p.m. ( EDT ) there was an automatic shutdown of Unit 2 due to a problem with the electrical transmission in the public network.
• On March 2, 2006, an alarm occurred in the fire alarm center of the nuclear power plant, which reported a fire in Block 2. A technician noticed that there was no fire. The reactor was shut down anyway. The incident was reported to the local regulatory authority.
• On April 29, 2006, Block 2 had to be shut down due to a water leak. Although this incident would not have affected the operation of the unit because the leak was too small, the reactor was shut down as a precautionary measure to repair the leak.
• On December 17, 2012, Unit 2 was automatically shut down during a routine turbine test. The cause is still being investigated.
