REACTOR CORE

The reactor core belongs to the field of nuclear power engineering. The reactor core includes at least one module, solid (4) and liquid neutron moderators. The module contains a casing (1), at least one heat pipe, one fuel element and thermal insulation (5). The heat pipe is made in the shape of a casing (2) with a wick (6), and contains a coolant. The fuel element is made of nuclear fuel (8), arranged in the evaporation area of the heat pipe around its casing (2) in thermal contact with it, and enclosed in a can (3). Low-melting metals with a high boiling point, for example, lithium, calcium, lead, silver are used as the coolant of the heat pipe. Thermal insulation (5) is arranged between the can (3) and the casing (1) of the module. At least one hole is made in the solid neutron moderator (4), in which at least one module is arranged. The space between the casing (1) of the module and the solid neutron moderator (4) is filled with a liquid neutron moderator. The technical result is an increase in the efficiency of reactor plants and the expansion of the scope of the core.
