Rainer Moormann (born 1950) is a German chemist and nuclear whistleblower.
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.
In 2008 Moormann published a critical paper on the safety of pebble bed reactors,[1][2] which raised attention among specialists in the field, and managed to distribute it via the media, facing considerable opposition.
[3][4] In 2020, Moormann co-authored a paper that argued in favor of keeping the by then six German nuclear power plants running in order to reduce CO2 emissions.
[5] 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)[6] and of the German section of the International Association of Lawyers against Nuclear Arms (IALANA).
