In March 2002, plant staff discovered that the borated water that serves as the reactor coolant had leaked from cracked control rod drive mechanisms directly above the reactor and eaten through more than six inches [23] (150 mm) of the carbon steel reactor pressure vessel head over an area roughly the size of a football (see photo).
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 ...
A new reactor is assembled with its control rods fully inserted. Control rods are partially removed from the core to allow the nuclear chain reaction to start up and increase to the desired power level. Neutron flux can be measured, and is roughly proportional to reaction rate and power level. To increase power output, some control rods are ...
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 ...
This is a list of electricity-generating power stations in the U.S. state of Ohio, sorted by type and name. In 2022, Ohio had a total summer capacity of 27,447 MW and a net generation of 135,810 GWh. [ 2 ]
The metal used for the tubes depends on the design of the reactor. Stainless steel was used in the past, but most reactors now use a zirconium alloy which, in addition to being highly corrosion-resistant, has low neutron absorption. The tubes containing the fuel pellets are sealed: these tubes are called fuel rods. The finished fuel rods are ...
Inside the core of a typical pressurized water reactor or boiling water reactor are fuel rods with a diameter of a large gel-type ink pen, each about 4 m long, which are grouped by the hundreds in bundles called "fuel assemblies". Inside each fuel rod, pellets of uranium, or more commonly uranium oxide, are stacked end to end.
The origin of the project explains why the Shippingport reactor used 93%-enriched uranium, unlike later commercial power reactors that do not exceed 5% enrichment. [5] Other significant differences from commercial reactors include the use of hafnium for its control rods, [13] although these were necessary and used only in the reactor's seed. [6]
