FIELD: power industry.
SUBSTANCE: group of inventions refers to design and erection of fuel assembly 10 for fast neutron nuclear reactor (FNNR) and namely for FNNR using liquid metal as heat carrier, for example sodium. According to this invention, assembly 10 includes pipe 2 with cross section in the form of polygon, which contains a pack of bars inside which there is fissible and/or reproducing material, and six projections each of which is located on one of external edges of the above pipe 2. Besides, assembly 10 includes support element 6 located inside pipe 2 and above the specified pack of bars, where projections 7 are attached to support element 6.
EFFECT: improvement of assembly.
