Quad Cities Generating Station is a two-unit nuclear power plant
Nuclear power plant
A nuclear power plant is a thermal power station in which the heat source is one or more nuclear reactors. As in a conventional thermal power station the heat is used to generate steam which drives a steam turbine connected to a generator which produces electricity.Nuclear power plants are usually...

Extended power uprate

During an extended power uprate test on March 5, 2002 (designed to extend the power efficiency of existing BWR reactors), Quad Cities Unit 2 began to experience vibrations in a steam line. On March 29 the plant was manually shut down due to high vibrations causing leaks in the main turbine control system. Unit 2 was restarted on April 2, but vibration broke a main steam pipe drain line. The line was repaired and the restart resumed, but by June 7 the main steam lines were showing unexplained aberrations. The plant was again taken offline for repairs on July 11, and the problem was traced to a hole in the steam dryer. The steam dryer was repaired and Unit 2 was restarted on July 21, 2002. The incident did not result in any increased probability of an accident. The NRC inspected all repairs and the extended power uprate was completed successfully.

defines two emergency planning zones around nuclear power plants: a plume exposure pathway zone with a radius of 10 miles (16.1 km), concerned primarily with exposure to, and inhalation of, airborne radioactive contamination, and an ingestion pathway zone of about 50 miles (80.5 km), concerned primarily with ingestion of food and liquid contaminated by radioactivity.

The 2010 U.S. population within 10 miles (16.1 km) of Quad Cities was 34,350, a decrease of 0.5 percent in a decade, according to an analysis of U.S. Census data for msnbc.com. The 2010 U.S. population within 50 miles (80.5 km) was 655,207, a decrease of 0.3 percent since 2000. Cities within 50 miles include Moline (19 miles to city center).

Seismic risk

The Nuclear Regulatory Commission's estimate of the risk each year of an earthquake intense enough to cause core damage to the reactor at Quad Cities was 1 in 37,037, according to an NRC study published in August 2010.
