Kivonat:
Nuclear reactors are a powerful source of energy but also of interesting 
nuclear physics. The future of nuclear energy is intensely debated, but in 
the mean time new reactor types are proposed and investigated.  They are 
expected to be safer and more reliable and produce less waste or even help to 
destroy the accumulated one. Their design requires new and more accurate data 
on neutron reactions (capture and fission) and also on decay data (beta 
delayed neutron fraction and energy released by the decay of fission 
products). Interestingly enough similar nuclear physics information is 
required to understand the evolution and death of stars and the fabrication 
of elements in the Universe (s-process and r-process). Nuclear reactors are 
also a powerful source of anti-neutrinos, which have been used by a new 
generation of experiments to demonstrate their oscillatory nature. They have 
revealed as well some anomalies, which could indicate “new physics” provided 
it is not due to more mundane nuclear physics phenomena. All this reveals a 
close connection between reactor technology, nuclear astrophysics and 
fundamental physics, which is more clearly shown by the fact that the same or 
very similar experiments can contribute to all of them. Examples of this will 
be shown.
