1947
AB Atomenergi was formed in 1947 for the purpose of developing, building and operating nuclear power stations in Sweden. Initially, 57 per cent of the company was owned by the Swedish state and the remainder by local government-owned and private electricity companies in Sweden, as well as some industrial enterprises.
1950's
The business largely consisted of basic research and development into the production of uranium as well as fuel and materials technology and was initially conducted in Stockholm. In 1954, the first Swedish experimental reactor was completed. Known as R1, it was located in an underground rock cavern in Stockholm. In the 1950s the company also established operations near Nyköping, where a number of laboratories and experimental reactors of various types were constructed.
1960's
Gradually, the activities were relocated from Stockholm to Nyköping, where intensive research activities continued. Studsvik's existing reactors, R2 and R2-0, were commissioned in 1960. In 1969, AB Atomenergi's resources for fuel fabrication and the design of nuclear reactors were taken over by Asea-Atom. At the same time, the Swedish state acquired all the shares in AB Atomenergi, whose business in the future was intended to comprise research and development activities and consulting services for the Swedish nuclear power industry.
1970's
In the 1970s the state successively reduced its funding for AB Atomenergi, as a result of which the financing of the business was gradually taken over by industry.
AB Atomenergi changed its name to Studsvik Energiteknik AB.
1980's
In the early years of the 1980s several new units were established or acquired.
The Group was re-organised into a nuclear division and an energy division. In 1987, the company changed its name to Studsvik AB.
1990's
The Swedish state transferred its shares in Studsvik AB to Vattenfall. The units that were not related to nuclear power were wound up or sold. Vattenfall successively divested its holding of shares in
Studsvik AB in the mid 1990s to private investment companies. In 1998, a Germany company, SINA Industrieservice GmbH, which is active in health physics and decontamination, was acquired. The nuclear power division of Scandpower AS in Norway, which develops in-core fuel management codes, was also acquired. The same year also saw the start of the construction of the facility in Erwin, Tennessee, for volume reduction of low- and intermediate-level radioactive waste from the US nuclear power industry. During 1998 the development of a method for treating brain tumours, based on the BNCT method, also started.
2000's
The Erwin facility in the USA was taken into commercial production in April 2000. Studsvik Polymer AB was divested with effect from December 31, 1999 to a British company, Bodycote Materials Testing Group. Studsvik AB was listed on Stockholmsbörsen's (Stockholm stock-exchange) O list on May 4, 2001.The business conducted by Studsvik Instrument AB was wound up in 2001.Some of its activities were taken over by Stensand Specialserviceföretaget AB and the remainder was either closed down or sold. The BNCT facility for the treatment of cancer patients was taken into operation. In June 2002, together with Washington Group Inc, Studsvik founded the company, THOR Treatment Technologies, LLC (TTT). The purpose of the company is to market waste management to the US Department of Energy and other players on the US federal nuclear waste market. An agreement was signed with Vattenfall concerning the acquisition of real-estate and the shares in AB SVAFO. The German group, Industrieanlagen Fritz & Marx (IFM) was acquired in April 2003. Studsvik's 50 per cent stake in Marieholm Stensand Industrirengöring AB (MSI) was sold to Skanska Miab on July 1, 2003.
In December 2004 Studsvik decides to cease its own reactor operations and initiates collaboration with Institutt for energiteknikk (IFE) in Norway.
Studsvik strengthens its position in the British market by acquiring Environmental Remediation Services Ltd in 2005. Studsvik acquires the ISS health physics business, with operations in Sweden, the United Kingdom and Canada. Studsvik signs an agreement with the State of South Carolina in the USA which will guarantee Studsvik disposal capacity at the Barnwell waste facility at a fixed price for the next three years.
On June 16, 2005, the operation of the R2 and R2-0 reactors is ceased and Studsvik Medical AB, the base for Studsvik's BNCT project is sold to Hammercap AB.
In 2006 Studsvik acquires the American company RACE LLC. In December 2006 Studsvik AB sold its wholly-owned subsidiary Stensand AB to Coor Service Management. In April 2007 Studsvik acquires the German company Dr Fary GmbH & Co KG. In August 2007 Studsvik acquires the English company Alpha Engineering Ltd.
