Location: NE
Operator: Nebraska Public Power Dist
Configuration: 815-MW BWR
Operation: 1974
Reactor supplier: GE
T/G supplier: WH
EPC: Burns & Roe
Quick facts: This is the largest single generating unit in Nebraska. Commercial operation was in Jul 1974. The plant is named after Nebraska public power pioneers Guy Cooper, Jr and Guy Cooper, Sr, whose family had begun electrification work in Humboldt, NE, in the late 1890s. The plant is operated by a management team from Entergy Nuclear under a support contract expiring in 2029. This contract was first signed in 2003 and extended in Feb 2010.

Fort Calhoun
Location: NE
Operator: Omaha Public Power Dist
Configuration: 526-MW PWR
Operation: 1974 (ret)
Reactor supplier: CE
T/G supplier: GE
EPC: Gibbs Hill Durham & Richardson
Quick facts: Fort Calhoun NPP has a 660ac site on the Missouri River north of Omaha. Planning began in 1966. The facility was extensively refurbished in 2006. Ft Calhoun was permanently closed at 12:55p CDT on 24 Oct 2016. At the time, it was the smallest NPP still operating in the USA.

Fort St Vrain
Location: CO
Operator: Public Service Colorado
Configuration: 343-MW HTGR
Operation: 1979 (ret 1989)
Reactor supplier: General Atomics
T/G supplier: GE
EPC: S&L, Ebasco
Quick facts: This was the only full-size HTGR built in the USA. PSC announced the project in Mar 1965, the CL application was filed in Oct 1966, and the CP was issued on 18 Sep 1968. Fuel loading began on 27 Dec 1973 and criticality was achieved on 31 Jan 1974 with the offical COD being 1 Aug 1979. Thereafter, the plant operated intermittently with numerous complex equipment and system issues needed resolution. In Dec 1988, the PSC Board decided to close the plant no later than Jun 1990 but more technical problems during the summer of 1989 caused the shutdwon to be advanced to 29 Aug 1989. The steam turbine was later repowered.

Location: NE
Operator: Atomic Energy Commission
Configuration: 75 MW equivalent HTGR
Operation: 1962 (ret 1964)
Reactor supplier: Atomics International
T/G supplier: GE
EPC: Atomics International, Bechtel, Peter Kiewit
Quick facts: Hallam was a 75-MWe, 240-MWt sodium-cooled, graphite-moderated reactor. Ground-breaking was on 28 Jun 1958 and testing of the reactor began in Aug 1961. Full power was achieved in May 1963. For about two years, steam was supplied to a 120-MW T/G set built for Sheldon coal-fired power station of Consumers Public Power Dist. In 1967, NPPD was authorized to decommission and dismantle the facility, a process concluded in 1969. The U.S. Dept of Energy currently maintains the remaining nuclear-related buildings.

Wolf Creek
Location: KS
Operator: Wolf Creek Nuclear Operating Co
Configuration: 1,226-MW PWR
Operation: 1985
Reactor supplier: WH
T/G supplier: GE
EPC: Bechtel, Daniel
Quick facts: Wolf Creek Nuclear Operating Corp was organized on 14 Apr 1986, to operate and eventually decommission Wolf Creek NGS. WCNOC is jointly-owned by Westar Energy (47%), KCPL 47%, and Kansas Electric Power Coop (6%). The site is near Burlington on 10,500ac. Callaway and Wolf Creek were built as sister units as part of the SNUPPS standardized nuclear plant design.
