The Salem Nuclear Power Plant is a two-unit nuclear power plant nuclear power plant located in Lower Alloways Creek Township, in Salem County, New Jersey, in the United States. It is owned by PSEG Nuclear LLC and Exelon Generation LLC.

Reactor Edit
The reactor, both PWR, was built by Westinghouse, and started commercial operations in 1977 (Unit 1) and 1981 (Unit 2). The two-unit plant has a capacity of 2,275 MWe. Unit 1 was licensed to operate until August 13, 2036 and Unit 2 was allowed to operate until April 18, 2040. In 2009, PSEG applied for a 20-year license renewal for both units, approved by the NRC in 2011.
Population Surrounding Edit
The Nuclear Regulatory Commission defines two emergency planning zones around a nuclear power plant: exposure zone zone with a radius of 10 miles (16 km), mainly related to exposure, and inhalation, airborne radio contamination and consumption line lanes about 50 miles (80 km ), mainly related to the consumption of food and fluids contaminated by radioactivity.
The 2010 US population within 10 miles (16 km) of Salem was 52,091, an increase of 54.1 percent in a decade, according to a US Census data analysis for msnbc.com. The US population of 2010 within 50 miles (80 km) is 5,482,329, an increase of 7.6 percent since 2000. Cities within 50 miles include Philadelphia (43 miles to the city center).
Security issues Edit
The New York Times has reported that, in the 1990s, Salem reactors were closed for two years due to maintenance problems. Consultants found some difficulties, including leaking generators, unreliable controls on reactors, and workers who were worried about reporting issues would lead to retaliation. In 2004, the Nuclear Regulatory Commission took additional oversight of the factories in Salem and increased their oversight.
Extensive investigations by the Nuclear Regulatory Commission, and subsequent review by employed consultants have found many minor issues, such as lack of regular maintenance and low morale among personnel, but state that the plant is safe.
On Thursday, August 22, 2013, Salem's nuclear plant was closed after a slightly radioactive water leak. The spill was confined to factory containment buildings, and regulators said there was no risk to the public. The factory resumed on August 24, after closing less than 48 hours.
In May 2014, the blackout scheduled for refueling in Salem 2 was extended after a breaking bolt from the coolant pump was found in the reactor vessel. Westinghouse sent a team to check the pump. Inspection reveals a bolt at the bottom of the coolant pump as well as the bottom of the reactor vessel. Unit 2 resumed operations on July 11, 2014.
Seismic risk Edit
The Nuclear Regulatory Commission's estimate of the risk of each year's strong earthquake to cause core damage to reactors in Salem is 1 in 90,909, according to an NRC study published in August 2010.
Water Usage Edit
Both reactors use Delaware Bay as a cooling water source. Salem units 1 and 2 have a water intake building with a rotating screen to collect debris that was then washed. Sometimes a thick layer of grass clogs the intake and the reactor runs with less power for weeks as a result. All the waste heat generated in the steam cycle (about 2 gigawatts) is discharged into the bay. The resulting increase in water temperature is set to less than 1 Ã, Â ° C in the summer months, and up to 2 Ã, Â ° C remainder of this year. The large covered cycle cooling tower on site is part of an adjacent Hope Creek plant and is not used by the Salem reactor.
Famous employees Edit
