Studsvik applies to build more reactors; Sweden seeks majority control of SMR company
New developments in Sweden’s nuclear energy industry continue to make headlines. Last week, Swedish engineering services firm Studsvik submitted an application to build between 600 MWe and 1,400 MWe of new nuclear power capacity “at and around” its Nyköping Municipality headquarters. Separately, the Swedish government is looking to acquire a majority ownership stake in Videberg Kraft AB.

For in-scope structures, systems, and components (SSCs), applications such as the Licensing Modernization Project (NEI 18-04 Rev. 1) and Reliability Integrity Management (ASME BPVC Section XI Division 2) call for setting low-level reliability targets that collectively satisfy various higher-level risk goals and also satisfy considerations related to defense in depth. In a specific plant design application, given • a PRA, • SSC-level reliability targets, • the associated SSC-level capability requirements assumed in the PRA, and • a good understanding of the stressors and processes that degrade the constituent materials of those SSCs, the processes associated with monitoring and non-destructive examination can be formulated so as to show whether SSC-level targets are being satisfied in operation. If they are not being satisfied, satisfaction of the plant-level goals may be threatened. The reliability targets chosen clearly affect not only the safety case, but also the resource implications of the required monitoring and non-destructive examination. The process of setting reliability targets is not yet standard, and panel discussion of that topic is expected to be fruitful.
