NUCLEAR REACTOR CORE

A nuclear reactor core relates to the field of atomic power. A nuclear reactor core comprises at least one module, a solid neutron moderator (5) and a liquid neutron moderator. The module comprises a housing (2), at least one heat pipe, at least one fuel element, a casing (1) and thermal insulation (6). The heat pipe is formed from a housing (3) and a wick (7), and contains an evaporating coolant. The fuel element consists of a shell (4) and nuclear fuel (9). An evaporation zone of the heat pipe and the fuel elements are enclosed in the casing (1) which is filled with a liquid coolant. Liquid metals having a high boiling point, for example lithium, calcium, lead and silver, are used as the heat pipe coolant and the liquid coolant in the casing (1). The thermal insulation (6) is placed in a space between the casing (1) and the module housing (2). The solid neutron moderator (5) has at least one opening in which at least one module is arranged. A space between the solid neutron moderator (5) and the module is filled with the liquid neutron moderator. The technical result is an increase in the efficiency of reactor plants and an extension of the field of use of a core.
