摘要
Abstract
The program of nuclear medical ship,funded by the cancer healing program of IAEA,was proposed according to the existing Miniature Neutron Source Reactor (MNSR)technology.The nuclear medical ship equipped with Boron Neutron Cap-ture Therapy(BNCT)device was developed,which opened a new scope of nuclear science application.The reactor of nuclear med-ical ship was designed in accordance with In-hospital Neutron Irradiator mark I (IHNI-1).In IHNI-1,heavy concrete was used as shielding material,and the reactor pool was cylindrical.Whereas,the volume and total weight of the reactor were too large to meet the ship’s requirement.After the design and optimization of the reactor’s shielding system by M-C method,stainless steel and B-polyethylene were chosen as shielding materials,and square pool was substituted by compact cylindrical pool.The result shows that on the premise of guaranteeing safety,shielding system’s mass and volume were cut down greatly,i.e.,this design can meet the requirement of nuclear medical ship.关键词
