Study of the physical characteristics of the BN-350 reactor on starting

Successive development phases for sodium-cooled fast reactors

“…In addition, some of the most important results of BN-350 operation are [8][9][10][11]: 1) reliability of the full-scale equipment of a power-generating unit operating in a sodium medium (reactor vessel and in-vessel mechanisms, pumps, heat-exchangers, pipelines, and fixtures Du 500 and Du 600, cold traps, and others); the failure of evaporators during the first few years of operations was due to manufacturing defects; 1) perfection of the technology used to prepare large sodium volumes (~1000 m 3 ), preparation of tanks, the reactor vessel, branching pipelines, and other large-size equipment for filling with sodium and the technology for filling the equipment; In addition, some of the most important results of BN-350 operation are [8][9][10][11]: 1) reliability of the full-scale equipment of a power-generating unit operating in a sodium medium (reactor vessel and in-vessel mechanisms, pumps, heat-exchangers, pipelines, and fixtures Du 500 and Du 600, cold traps, and others); the failure of evaporators during the first few years of operations was due to manufacturing defects; 1) perfection of the technology used to prepare large sodium volumes (~1000 m 3 ), preparation of tanks, the reactor vessel, branching pipelines, and other large-size equipment for filling with sodium and the technology for filling the equipment;…”
