It offers engineering and consultancy, fuel and materials testing, fuel and reactor management software, nuclear and radioactive hazards lifecycle management, nuclear decommissioning facilities, and radioactive waste management designing processes, as well as isotopes for medical and industrial applications. The company also provides fuel and materials technology services comprising fuel qualification, plant life management, hot cell technology, final storage research, and transport of irradiated materials. In addition, it offers a range of products, such as The Excavator Mounted Bucket Assay System designed to assay and determine the radiological contents of excavator bucket; Freeze-Tec for waste management issues; Fluid Bed Steam Reforming for waste treatment; CASMO5, a lattice physics code for modeling power-dependent limits (PWR) and thermal limits (BWR) fuel; HELIOS-2, a generalized-geometry lattice physics code; and SIMULATE5, a 3D multi-group nodal code for the analysis of PWRs and BWRs. Further, the company provides SIMULATE-3K, a two-group nodal code for analysis of PWRs and BWRs; XIMAGE, a graphical fuel management and loading pattern optimization suit; S3R that enables cycle-specific core modeling on the training simulator; GARDEL, an online core monitoring suite with built-in reactivity management tools; MARLA, a tool for planning and optimizing BWR fuel shuffles; and SNF, which calculates isotopic concentrations, radiation source terms, and decay heat of spent PWR and BWR fuel. The company was formerly known as Studsvik Energiteknik AB and changed its name to Studsvik AB (publ) in 1987. Studsvik AB (publ) was founded in 1947 and is headquartered in Nyköping, Sweden.
