1) nuclear reactor
2) pile
3) atomic pile
4) reactor
5) atomic reactor
6) fission reactor
a device in which a self-sustaining nuclear fission chain reaction can be maintained and controlled
GRM: n, (1,2,3,4,5,6)
Note: the term is sometimes applied to a device in which a nuclear fusion reaction can be produced and controlled, i.e. a fusion reactor
