Beaver Valley-2 Nuclear Power Plant, United States

The Beaver Valley nuclear power plant is a nuclear power plant that produces electricity on the Ohio River in the city of Shippingport, in the county of Beaver, in the western corner of Pennsylvania, USA. The last two nuclear reactors of the nuclear power plant were approved for commissioning in 1975 and 1986, while the previous 1957 Atomic Energy Station for Vessels was permanently closed in 1982. The original work was the first power plant nuclear in the United States.

The two facilities are located in the same place on the Ohio River. The maximum installed power in the current plant with two reactors is 1 738 MW, and the annual production in 2007 was approximately 14.53 TWh of electricity, which was higher than the average production of the last five years.

The nuclear plant is owned by FirstEnergy Nuclear Operating Co. The nuclear power facility has a total of two reactors in operation, each with 920 megawatts (MW) and 970 megawatts (MW) of power.

Surrounding Population

The Nuclear Regulatory Commission defines two emergency planning zones around the nuclear power plants: an area of exposure path of plumes with a radius of 10 miles (16 km), which is mainly concerned with the exposure and inhalation of pollution radioactive in the air and an ingestion path zone of about 50 miles (80 km), is primarily concerned with the ingestion of food and liquids contaminated by radioactivity.

According to an analysis of the US Census data. In, the population of the USA. In 2010 at a distance of 10 miles (16 km) from Beaver Valley was 114,514, a decrease of 6.6 percent in a decade. The 2010 US population at 50 miles (80 km) was 3,140,766, a decrease of 3.7 percent since 2000. The cities at 50 miles include Pittsburgh (27 miles against the city center).

The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake severe enough to cause damage to the reactor core in Beaver Valley was Reactor 1: 1 at 20,833; Reactor 2: 1 at 45,455, according to an NRC study published in August 2010.

Pressurized Water Nuclear Reactor

The reactor at the Beaver Valley nuclear power plant is a reactor of the PWR ( pressurized water reactor) type. The nuclear water pressure reactor is the type of nuclear reactor most used worldwide in nuclear power plants. Its main characteristic is the use of water subjected to high pressure in the primary circuit to prevent it from boiling.

The nuclear fuel used in this type of reactor is Uranium.

Operation of the Pressurized Water Nuclear Reactor

Operation of pressurized water nuclear reactors is divided into 4 main steps: initially the reactor core inside the reactor vessel generates heat. Finally, the high-pressure water from the primary circuit transports this heat to a steam generator. Next, inside the steam generator, the heat coming from the primary circuit converts the water in the secondary circuit into steam. Finally, the generated steam drives a turbine that produces electricity.
