Reactor core component of neutron source device of hospital neutron irradiator-I

Abstract

The invention relates to a reactor core component of a neutron source device of a hospital neutron irradiator-I. The reactor core component has the advantages of being low in production cost, easy and convenient to operate and maintain, safe to use, low in operation cost, pollution-free to environment and can be built directly in hospitals and the like, so that the reactor core component is an ideal device as a neutron source of the neutron irradiator. The device realizes innovation and invention of the four reactor core important components, such as a high-equivalent central control rod, a high-effect responsive regulator, a graphite tile and aluminium tile piece adaptive to neutron spectrum as well as low-concentration design of a reactor core fuel element and update of fuel assembly structure material and the like. On the basis that the intrinsic security of a reactor and extremely-low uranium filling volume are maintained and operation is done under nuclear-free engineering personnel caring conditions, the reactor for scientific research which is only used in small sample element activation analysis is developed to be a high-tech clinic cancer-curing medical instrument. The specially-designed reactor core component forms the four mutually-associated invention points in the invention.

Description

technical field [0001] The invention relates to a core component of a hospital neutron irradiator-I neutron source device, in particular to a core component of a hospital neutron irradiator-I neutron source device in the field of high-end clinical cancer treatment medical equipment . Background technique [0002] Boron neutron capture therapy is a new binary targeted therapy technology for the treatment of malignant tumors that is currently being researched and developed in many countries and regions. They all use the existing high-power experimental research reactor as a neutron source, and carry out the experimental tunnel Modified. Because such piles are all built in nuclear technology research centers or universities, away from residential areas and hospitals, it causes great inconvenience and difficulty to the treatment of patients. Therefore, there is an urgent need to provide a new type of core component of the hospital neutron irradiator-I neutron source device. ...
