Marble Hill Nuclear Power Station was an unfinished nuclear power plant in Saluda Township, Jefferson County, near Hanover, Indiana, USA. In 1983, the Public Service Company of Indiana announced it was abandoning the half-finished nuclear power plant, on which $2.5 billion had already been spent.
Construction at Marble Hill began in 1977 and ended in 1984, when the Public Service Company of Indiana (PSI), now Duke Energy, abandoned the half-finished nuclear power plant. With $2.5 billion spent and, as the most expensive nuclear construction project ever abandoned, Marble Hill was a devastating setback for the troubled nuclear power industry, which saw more than 100 plant cancellations following the Three Mile Island accident near Harrisburg, Pennsylvania, in March 1979. On March 18, 2005, demolition of the unfinished facility began.
Long before 1984, Marble Hill had been a controversial enterprise. During 1978 and 1979, regional Ohio Valley environmental advocacy group The Paddlewheel Alliance staged two non-violent "occupations" of the PSI property. [1] As ongoing local support dwindled, Marble Hill's fate rested with Indiana's state government, and PSI sought state funding guarantees for Construction Work in Progress (CWIP).
Eventually, PSI announced it had to abandon Marble Hill because of an overwhelming increase in costs and a shortage of funds to finish construction. [2] In October 1985, PSI staged an auction for roughly $8 million worth of already purchased reactor hardware. [3]
PSI planned to connect the nuclear plant to its network via a pair of 765 kV power lines and by looping in an existing, nearby 345 kV power line. The original plan included a 765 kV line to the existing Columbus substation, just south of Columbus, Indiana, and another 765 kV line to be built to a new substation near Rushville. However, plans for the Marble-Hill-to-Rush 765 kV power line were replaced with plans for a 765 kV link to American Electric Power's Jefferson Station, near Madison (and Clifty Creek Power Plant). Presumably, they would benefit PSI since the AEP Jefferson-Dumont 765 kV power line included an intermediate PSI interconnection substation near Greentown, Indiana.
Transmission line construction began before the plant was completed, but was halted before wires could be strung. For many years, the guyed-V 765 towers stood without wires, until they were purchased by AEP to replace structures on the Jefferson-Dumont line that were destroyed by cascading line failure from an ice storm in the early 1990s.
The two signature containment buildings which would have housed two 1130 MWe Westinghouse pressurized water reactors and the two cooling tower complexes were located just north of the containment buildings. (See photo.) The station was a near architectural one-for-one with Byron and Braidwood stations. The lower portion of the reactor vessel in Unit #1 was already installed at the time construction was halted. The turbine building behind the containment buildings has been demolished, although the multi-story concrete turbine foundations still stand, with what remains of the Unit #1 turbine still in place. During 1990, Power Equipment Supply Co. ("PESCO") was incorporated in Indiana and was established to sell equipment and parts from the Marble Hill Facility project. PESCO also purchased equipment for resale, brokered equipment, and sold equipment on consignment for others. Public Service Indiana discontinued PESCO operations in early 1996.
Marble Hill is currently owned by an undisclosed Michigan-based company and under demolition with a contract from MCM Management Corp. Since 2008, the facility was undergoing continued demolition, in which the Fuel Handling building (the smaller square building between the two containment buildings) was slowly being torn away and scrapped. In August 2010, one of the containment buildings was completely demolished, and the other had its reactor core removed, and was under heavy demolition. By May 2011, most Marble Hill structures were either demolished, or under demolition. As of December 2011, both containment domes had been demolished, with approximately 2/3 of the cooling stacks standing. The control building was also under heavy demolition.
The Chernobyl Nuclear Power Plant (ChNPP) is a nuclear power plant undergoing decommissioning. ChNPP is located near the abandoned city of Pripyat in northern Ukraine, 16.5 kilometers (10 mi) northwest of the city of Chernobyl, 16 kilometers (10 mi) from the Belarus–Ukraine border, and about 100 kilometers (62 mi) north of Kyiv. The plant was cooled by an engineered pond, fed by the Pripyat River about 5 kilometers (3 mi) northwest from its juncture with the Dnieper River.
Chapelcross nuclear power station is a former Magnox nuclear power station undergoing decommissioning. It is located in Annan in Dumfries and Galloway in southwest Scotland, and was in operation from 1959 to 2004. It was the sister plant to the Calder Hall nuclear power station plant in Cumbria, England; both were commissioned and originally operated by the United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the UK's nuclear weapons programme, but they also generated electrical power for the National Grid. Later in the reactors' lifecycle, as the UK slowed the development of the nuclear deterrent as the cold war came to a close, power production became the primary goal of reactor operation.
Donald C. Cook Nuclear Plant is a nuclear power plant located just north of the city of Bridgman, Michigan which is part of Berrien County, on a 650-acre (260 ha) site 11 miles south of St. Joseph, Michigan, United States. The plant is owned by American Electric Power (AEP) and operated by Indiana Michigan Power, an AEP subsidiary. It has two nuclear reactors and is currently the company's only nuclear power plant.
A containment building is a reinforced steel, concrete or lead structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radioactive steam or gas to a maximum pressure in the range of 275 to 550 kPa. The containment is the fourth and final barrier to radioactive release, the first being the fuel ceramic itself, the second being the metal fuel cladding tubes, the third being the reactor vessel and coolant system.
Inverkip power station was an oil-fired power station on the Inverclyde coast, Firth of Clyde, west coast of Scotland. It was closer to Wemyss Bay than Inverkip, and dominated the local area with its 236 m (774 ft) chimney, the third tallest chimney in the UK and Scotland's tallest free-standing structure. In common with other power stations in Scotland it lacked cooling towers; instead, sea water was used as a coolant. The station consisted of three generating units with a combined total rating of 2028 megawatts (MW).
The Saxton Nuclear Experiment Station, also known as the Saxton Nuclear Generating Station or Saxton Nuclear Experimental Corporation Facility, was a small nuclear power plant located in Bedford County, near Saxton, Pennsylvania.
Connecticut Yankee Nuclear Power Plant (CY) was a nuclear power plant located in Haddam Neck, Connecticut. The power plant is on the Connecticut River near the East Haddam Swing Bridge. The plant was commissioned in 1968, ceased electricity production in 1996, and was decommissioned by 2004. The reason for the closure was because operation of the nuclear power station was no longer cost effective. The plant had a capacity of 582MW. Demolition of the containment dome was completed the week of July 17, 2006.
The William H. Zimmer Power Station, located near Moscow, Ohio, was a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Today, the plant is owned and operated by Vistra Corp.
Bradwell nuclear power station is a Magnox-design nuclear power station that is undergoing decommissioning. It is located on the Dengie peninsula at the mouth of the River Blackwater, Essex. In 2019, it was the first nuclear power station in the UK to be placed into long-term decommissioned management. As of 2016, China General Nuclear Power Group is considering Bradwell for the site of a new nuclear power station, named Bradwell B.
Clifty Creek Power Plant is a 1,300-MW coal-fired power station located in Madison, Indiana. Clifty Creek is operated by the Indiana Kentucky Electric Corporation. It is named after Clifty Creek, which enters the Ohio River nearby.
Carolinas–Virginia Tube Reactor (CVTR), also known as Parr Nuclear Station, was an experimental pressurized tube heavy water nuclear power reactor at Parr, South Carolina in Fairfield County. It was built and operated by the Carolinas Virginia Nuclear Power Associates. CVTR was a small test reactor, capable of generating 17 megawatts of electricity. It was officially commissioned in December 1963 and left service in January 1967.
The Cherokee Nuclear Power Plant is an incomplete energy project 10 miles (16 km) outside Gaffney, South Carolina, United States. In the early 1970s, Duke Power started construction on a three-reactor nuclear power plant at the site. However, the project stalled due to economic problems by the early 1980s, leading to the project's eventual abandonment. In 1987, the power plant was the site of an underwater film studio built by Hollywood director James Cameron, for the film The Abyss.
R4 nuclear reactor was a nuclear reactor built at Marviken, Vikbolandet and the fourth nuclear reactor built in Sweden. It was heavy water moderated and intended for the dual role of 130 MWe of power generation as well as plutonium production. It had a central role in the Swedish nuclear weapon programme. During the mid 1960s, the social democratic government officially abandoned the project of designing Swedish nuclear weapons and the Marviken plant became derelict. It was never loaded with fuel, and the project was cancelled in 1970.
The Fukushima Daiichi Nuclear Power Plant is a disabled nuclear power plant located on a 3.5-square-kilometre (860-acre) site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant suffered major damage from the magnitude 9.1 earthquake and tsunami that hit Japan on March 11, 2011. The chain of events caused radiation leaks and permanently damaged several of its reactors, making them impossible to restart. The working reactors were not restarted after the events.
The Brennilis Nuclear Power Plant (EL-4) is a decommissioned site located in the Monts d'Arrée in the commune of Brennilis in Finistère, France.
The Kursk Nuclear Power Plant is one of the three biggest nuclear power plants (NPPs) in Russia and one of the four biggest electricity producers in the country. It is located on the bank of the Seym River about 40 kilometers west of the city of Kursk, midway between it and the town of Lgov, in western Russia. The nearby city of Kurchatov was founded when construction of the plant began. The plant feeds the grid for Kursk Oblast and 19 other regions. As of 2024, the site houses two active reactors and two decommissioned older units. It also houses the partially built Kursk 5 and Kursk 6 units which had construction halted, and two new VVER designs are under construction.
The three primary objectives of nuclear reactor safety systems as defined by the U.S. Nuclear Regulatory Commission are to shut down the reactor, maintain it in a shutdown condition and prevent the release of radioactive material.
The Hartsville Nuclear Plant is a canceled nuclear power plant project located near Hartsville, Tennessee. To be built and operated by the Tennessee Valley Authority (TVA), it was to have four General Electric boiling water reactors.
The Purdue University Reactor Number One (PUR-1) is a research reactor in West Lafayette, Indiana, United States. It is used primarily for teaching purposes in Purdue University's School of Nuclear Engineering. Built in 1962, the PUR-1 is the only nuclear reactor operating in the US state of Indiana. It was the second reactor installed in Indiana, and was the first critical reactor, after a sub-critical reactor was installed at Valparaiso University in 1958.
General Electric's BWR product line of boiling water reactors represents the designs of a relatively large (~18%) percentage of the commercial fission reactors around the world.
