Studsvik has long experience of thermohydraulic analysis and development of calculation models. An often-used calculation tool is the thermohydraulic system simulation code RELAP5.
Extensive calculation models have been developed for several of the Swedish reactor facilities. Simulations of feedback from control and safety systems and core kinesthetics constitute important components of models and analyses. Other areas of calculation consist of detailed analysis of flow and temperature fields with regard to CFD methods. We also undertake investigations, such as evaluation of regulatory requirements and review of safety analysis reports for facilities, such as primary safety review of preliminary safety analysis report ahead of plant change.s
