Rainer Moormann (born 1950) is a German chemist and nuclear power whistleblower. He grew up in Osnabrück. After finishing highschool he studied physical chemistry in Braunschweig and received a doctor's degree with Raman spectroscopic and theoretical investigations on hydrogen bonds in liquids. Since 1976 he has been working at the Forschungszentrum Jülich, doing research on safety problems with pebble bed reactors (especially with the AVR reactor), fusion power and spallation neutron sources.
In 2008 Moormann published a critical paper on the safety of pebble bed reactors, which raised attention among specialists in the field, and managed to distribute it via the media, facing considerable opposition.
For doing this despite the occupational disadvantages he had to accept as a consequence, Moormann was awarded the whistleblower award of the Federation of German Scientists (VDW) and of the German section of the International Association of Lawyers Against Nuclear Arms (IALANA).
