The Savannah rods were air cooled to room temperature on the cooling bed and then were cold straightened in a Medart Straightener. Rods to be beta heat treated by-pass the cooling bed and were lifted into the beta heat treating furnace by means of a hoist, to be held at 1,320–1,365 °F for 11–20 minutes and then quenched in cold water.
Control rod assembly for a pressurized water reactor, above fuel element Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium . Their compositions include chemical elements such as boron , cadmium , silver , hafnium , or indium , that are capable of absorbing many neutrons without ...
The Perry Nuclear Power Plant is located on a 1,100 acres (450 ha) site on Lake Erie, 40 miles (64 km) northeast of Cleveland in North Perry, Ohio, US. The nuclear power plant is owned and operated by Vistra Corporation. The reactor is a General Electric BWR-6 boiling water reactor design, with a Mark III containment design. The original core ...
Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio, that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission (AEC), the U.S. nuclear weapons program and Navy nuclear propulsion; in later years, it produced low-enriched uranium for fuel for ...
The reactor was shut down from 2002 until early 2004 for safety repairs and upgrades. In 2012 the reactor supplied 7101.700 GWh of electricity. [14] In 1973, two more reactors were also ordered from Babcock & Wilcox. However, construction on Units Two and Three never commenced, and these two units were officially canceled in 1981. [15]
Fermi 2 is a 1,202 MWe General Electric boiling water reactor owned and operated by DTE Energy. Plans to build were announced in July 1968. Initial criticality was achieved in July 1985, and full commercial operation commenced on January 23, 1988. [5] The reactor vessel holds 764 fuel assemblies and 185 control rods which modulate the power.
The plant was first proposed February 1, 1956 when the local public utility company in Piqua, Ohio proposed to build a 12,500 kilowatt nuclear power plant using an organically moderated reactor by asking to join the U.S. government's small reactor construction program which provided joint government-utility participation.

Its single Combustion Engineering pressurized water reactor weighs 425 tons and has steel walls 8 + 1 ⁄ 2 inches (220 mm) thick. The containment building is 116 feet (35 m) in diameter and 189 feet (58 m) tall, including the dome. Its concrete walls are 3 + 1 ⁄ 2 feet (1.1 m) thick with a 1 ⁄ 4-inch-thick (6.4 mm) steel liner plate. The ...
