NPP WITH 3-CIRCUIT REACTORS

The three-circuit scheme is used at nuclear power plants with fast neutron reactors with sodium coolant of the BN type. To prevent contact of radioactive sodium with water, a second circuit with non-radioactive sodium is constructed. Thus, the circuit turns out to be three-circuit.

Nuclear power solves the problem of exhaustion of natural organic energy sources (coal, gas, oil) and removes the difficulties of moving large quantities of traditional fuel over long distances and to remote settlements.

Miniature nuclear power plants are very efficient and convenient sources of energy for submarines and large surface vessels. Electricity generated by nuclear power plants is among the cheapest.

All developed countries are moving towards an increasingly widespread use of nuclear power plants.

The share of electricity generated by nuclear power plants in France is approaching 80%. In Belgium, this share is about 60%, in Sweden – 42%, South Korea – 40%, Switzerland – 38%, Spain – 36%, Finland – 32%, Japan – 31%, Germany – 30%, England – 26%, USA – 21%, Russia – 13%..
