Low Level Waste Repository

The established nuclear industry in South Australia is focused on uranium mining, milling and the export of uranium oxide concentrate for use in the production of nuclear fuel for nuclear power plants.
 The state is home to the world's largest known single deposit of uranium, which is worked by BHP Billiton at the Olympic Dam mine.
 Contaminated legacy sites exist at Maralinga and Emu Field, where nuclear weapons tests were conducted in the 1950s and 1960s and at former uranium mines and milling sites.
 Nuclear waste is stored by CSIRO at Woomera and future waste storage prospects were considered during the deliberations of the Nuclear Fuel Cycle Royal Commission in 2016.
 The Commission has recommended that South Australia considers opportunities in nuclear waste storage (including developing a repository for spent nuclear fuel), the establishment of a nuclear fuel leasing scheme and the repeal of prohibitions which currently prevent future nuclear industrial development nationally.
The Yucca Mountain Nuclear Waste Repository, as designated by the Nuclear Waste Policy Act amendments of 1987, is to be a deep geological repository storage facility within Yucca Mountain for spent nuclear fuel and other high level radioactive waste in the United States.
 The site is located on federal land adjacent to the Nevada Test Site in Nye County, Nevada, about 80 mi northwest of the Las Vegas Valley.
James 'Jim' Wilson Voss is an American senior nuclear engineer who has managed nuclear materials and radioactive waste since graduating from Arizona University in the 1970s.
 Voss became known to Australians through his managing directorship of Pangea Resources, a consortium which planned to establish a nuclear waste repository in Australia in the late 1990s.
 Pangea's proposal was ultimately rejected following the efforts of the anti-nuclear movement in Australia.
 Voss is currently working at UCL Australia as an Honorary Reader.
 As of 2015 Voss is a partner at Predicus Consulting and a director of companies in the USA and the United Kingdom.
Yucca Mountain is a mountain in Nevada, near its border with California, approximately 100 mi northwest of Las Vegas.
 Located in the Great Basin, Yucca Mountain is east of the Amargosa Desert, south of the Nevada Test and Training Range and in the Nevada National Security Site.
 It is the site of the Yucca Mountain nuclear waste repository, which is currently identified by Congressional law as the nation's spent nuclear waste storage facility.
 However, while licensure of the site through the Nuclear Regulatory Commission is ongoing, political maneuvering led to the site being de-funded in 2010.
Robert Frank "Bob" List (born September 1, 1936) is an American attorney and politician.
 He served as the 24th Governor of Nevada from 1979 to 1983.
 He was raised in Exeter, California.
 He served as the Carson City District Attorney and the Nevada Attorney General before becoming governor.
 Currently List practices law in Las Vegas with the law firm Kolesar & Leatham, Chtd.
 He was the last Governor to serve from outside Clark County until Jim Gibbons' election.
 After his term ended, he became a supporter of the Yucca Mountain nuclear waste repository.
 List was defeated for re-election in 1982 by Nevada Attorney General Richard Bryan.
 He is a member of the Republican Party.
A deep geological repository is a nuclear waste repository excavated deep within a stable geologic environment (typically below 300 m or 1000 feet).
 It entails a combination of waste form, waste package, engineered seals and geology that is suited to provide a high level of long-term isolation and containment without future maintenance.
 The Waste Isolation Pilot Plant, under construction in the USA, is the only one which actually contains nuclear waste.
 However, the facility suffered a chemical explosion which led to a serious radiological accident in 2014.
The Onkalo spent nuclear fuel repository is a deep geological repository for the final disposal of spent nuclear fuel, the first such repository in the world.
 It is currently under construction at the Olkiluoto Nuclear Power Plant in the municipality of Eurajoki, on the west coast of Finland, by the company Posiva.
 It is based on the KBS-3 method of nuclear waste burial developed in Sweden by Svensk Kärnbränslehantering AB (SKB).
Yucca Mountain Johnny is a cartoon miner created by the United States Department of Energy (DOE) to present information to children on nuclear waste disposal and the Yucca Mountain Project.
 Serving as the virtual guide for the DOE's Youth Zone web site and appearing "live-action" in Nevada schools, Yucca Mountain Johnny has drawn harsh criticism as a propaganda tool.
Gudmundur Svavar (Bo) Bodvarsson (November 11, 1952 – November 29, 2006) was an Icelandic hydrogeologist who is known for his work with the Yucca Mountain nuclear waste repository.
 From 1980 until his death, he was affiliated with the Berkeley Lab, serving as the director of its earth science division from 2001.
 He was also a prolific writer on the subject of hydrology.
Low Level Waste Repository (LLW Repository Ltd) is the UK's low-level radioactive waste repository located on the West Cumbrian coast, on the seaward side of the Cumbrian Coast Line, approximately 6 km south east of the Sellafield nuclear site at Drigg village.
 The site stores waste from Sellafield, MoD sites, nuclear power stations, hospitals, universities, medical companies and the oil industry.
 It has been operating since 1959.
