Facts & figures
Around 400 employees work every day at GRS. Our scientists come from a wide range of disciplines - from engineering sciences to physics, geology, chemistry and meteorology to computer science and law.
Competences and services
Our employees research and assess issues in the fields of reactor safety - including nuclear safety in fuel supply, decommissioning and dismantling, storage, disposal, physical protection, radiation protection, environment and energy.
We work on around 450 projects each year. Last year, we documented the results of our work in numerous research reports and scientific publications, many of which can be found in our publications database. Another outcome of our work are our simulation codes, which can be used, for example, to represent the behaviour of nuclear power plants in the event of an accident or to model various processes developing in repositories. The calculation codes are currently used by more than 170 institutes from 40 different countries.
