Mainly a LMAW (low and medium level radioactive waste) processing site. Studsvik is located on the east coast of Sweden, Close to the town of Nyköping, x km south of Stockholm, and waste is transported to its harbor from the european continent for processing, and back.[3] The processing comprises melting of metal components in order to recycle the metal, and burning of dry materials in order to reduce the volume for disposal. The site is owned by the private company Studsvik AB, which besides waste treatment provides a wide range of services to the nuclear industry, mainly relating to decommissioning, maintenance, engineering, and software.[4][5] There are two decommissioned research reactors in Studsvik awaiting dismantling, and there have been three more which are now completely dismantled.[6] The site was founded in the 1950's by AB Atomenergi, a partly state-owned, partly industry-owned company which was founded 1947 with the purpose of developing swedish nuclear technology (both civil and military) and uranium mining.[7] By the 1960's-70's shift, most of the original purposes of AB Atomenergi were outdated or taken over by other bodies, and a process of re-organisation and privatisation started. In the 90's the state transferred its last shares in Studsvik AB to Vattenfall, who then transferred them to private investment companies, and the company started to expand internationally as well.[8] Studsvik AB is listed on the NASDAQ OMX Stockholm.[9] It has employees in seven countries, e.g. Sweden, Germany, USA, UK, and its activities in continental Europe are based in Pforzheim, Germany.[10]

There's two decommissioned, undismantled research reactors at Studsvik:

  • R2 - In operation 1960-2005, awaiting dismantling. (more info to be added)
  • R2-0 - In operation 1960-2005, awaiting dismantling. (more info to be added)

Totally dismantled research reactors:

  • Zebra (Zero Energy Bare Reactor Assembly) - constructed 1953 in central Stockholm, moved to Studsvik 1960, decommissioned and dismantled in the 1980's [11]
  • R0 - in operation 1959-early 1970's & dismantled [12]
  • FR-0 - in operation 1964-1971 [13], totally dismantled, facilities in other use [14]

AB Atomenergi has also previously operated:

  • Research reactor R1 - in operation 1954-1970, totally dismantled 1982. Located in central Stockholm (in the same facilities as ZEBRA). Sweden's first nuclear reactor.[15] After it was decommissioned 1970, the waste was moved to Studsvik, where it was supposed to be stored until 2007, when it was supposed to be shipped to Sellafield, and then back to Sweden for final disposal.[16]
  • (In cooperation with Vattenfall) R3/Ågesta ("Adam") - In operation 1963-74. In principle still totally intact. Located in Huddinge, the municipality next to Stockholm.
  • (In cooperation with Vattenfall) R4/Marviken ("Eva") - finished 1968 but never put in operation, closed down 1970. Reactor tank still intact, and was used for various experiments by Studsvik AB in the 80's and 90's.[17] Located on a peninsula on the southeast coast of Sweden.
