Neutron irradiation treatment module for medical ship

Abstract

The invention belongs to the technical field of radioactive irradiation treatment, and particularly relates to a neutron irradiation treatment module for a medical ship. The neutron irradiation treatment module is arranged on the medical ship. The neutron irradiation treatment module is a cubic-type square cabin and is divided into four layers from bottom to top, and a vertically arranged cylindrical stack body and a pool are disposed at the center of the neutron irradiation treatment module and penetrate through the space of the first layer to the fourth layer; and the first layer located at the lowermost layer is provided with an observation room, a mixed beam irradiation room and a superheat beam irradiation room, the second layer is provided with a loading and unloading transport passage, the third layer is provided with a reactor main control room and a reactor stack hall, and the forth layer at the top is provided with a transfer crane. The neutron irradiation treatment module meets the nuclear radiation protection requirements, the module space size is combined with a hull structure, the arrangement of human flow, logistics and emergency escape channels is realized, the radioactive zoning management of activities such as operation, maintenance, refueling and spent fuel outward transportation during the active period of the reactor is realized, and evacuation of personnel in an emergency state is ensured.

Description

technical field [0001] The invention belongs to the technical field of radiation irradiation therapy, and in particular relates to a neutron irradiation therapy module used in a medical ship. Background technique [0002] Boron neutron capture therapy (BNCT) is a biologically targeted radiation therapy mode with "inherent" safety. It injects non-toxic boron-containing drugs with pro-tumor tissue into the patient's body. When thermal neutrons or epithermal neutrons irradiate the tumor site, the neutrons contact the boron-10 nuclide in the cancer cells and undergo a nuclear reaction, and the released He ions and Li ions move in the opposite direction. The energy is enough to kill cancer cells, and the side effects are very serious. Small. At present, the neutron sources used for BNCT mainly include nuclear reactor neutron sources and accelerator-based neutron sources. Compared with accelerator-based neutron sources, nuclear reactor neutron source devices are smaller in size a...

AI Technical Summary

Problems solved by technology

The medical ship mainly includes the engine room, the driving room, the living area, the conventional treatment module and the neutron irradiation treatment module. The existing model is a land-based reactor. Obviously, its shape and structure and the overall layout of various process systems cannot be copied and used. It needs to be combined with the overall design of the hull and consider factors such as the construction, operation, maintenance and refueling of the reactor on the ship.
