MEDICAL NEUTRON SOURCE, NUCLEAR REACTOR FOR MEDICAL NEUTRON SOURCE, METHOD FOR USING MEDICAL NEUTRON SOURCE

摘要

FIELD: nuclear physics; medicine.SUBSTANCE: invention relates to neutron therapy of human malignant tumors. Invention comprises feeding, into a nuclear reactor core of a medical neutron source in a subcritical state, a heat carrier is supplied with specified temperature. Nuclear reactor core is brought out of subcritical state into critical state to reach rated power of nuclear reactor. Neutron output channel is opened for a neutron therapy session and operation of reactor is maintained at rated power during neutron therapy session. After expiry of time for neutron therapy session, neutron output channel is closed while simultaneously transferring reactor core into subcritical state. Heat carrier temperature at input of core is kept invariable and equal to preset temperature during transfer of core into critical state, and in process of nuclear reactor operation at rated power.EFFECT: higher safety of neutron source.26 cl, 8 dwg
