摘要： The invention relates to the field of nuclear physics and medicine, and specifically to the neutron therapy of malignant tumors in humans. A coolant having a set temperature is fed into the nuclear reactor core of a medical neutron source, which is in a subcritical state. The nuclear reactor core is transitioned from the subcritical state to a critical state until the nominal power of the nuclear reactor is achieved. A neutron output channel is opened in order to conduct a neutron therapy session, and the operation of the reactor is maintained at nominal power while the neutron therapy session is conducted. At the end of the neutron therapy session, the neutron output channel is closed at the same time as the reactor core is transitioned to a subcritical state. The temperature of the coolant entering the core is maintained un-changed and equal to a set temperature, both when the core is transitioned to a critical state and during the operation of the nuclear reactor at nominal power.

摘要： The invention relates to the field of nuclear energy, more particularly to low-power and particularly low-power reactors. A nuclear reactor contains a housing with a reflector which forms a reactor core. The core has arranged therein primary process tubes, which are intended for circulating a coolant, and secondary process tubes, which are intended for accommodating elements of a control and protection system. The reactor also contains an intake chamber for coolant of a primary loop, and a discharge chamber for coolant of the primary loop, which are separated by a partition. The primary process tubes are designed in the form of Field tubes, the outer tubes of which are secured on the bottom of the intake chamber for the coolant of the primary loop, and the inner tubes are secured on the partition. Fuel assemblies are mounted in the inner tubes of the Field tubes on suspensions, which are secured on an upper portion of the discharge chamber for the coolant of the primary loop. The secondary process tubes are sealed off from the intake and discharge chambers for the coolant of the primary loop, and the inter-tube space of the core is filled with a medium or material which is transparent to neutrons.
