摘要:
介绍深圳大学核技术所近年来对微型反应堆进行的一系列改进,包括:采取特殊措施,延长微堆安全运行时间,从原来的6-8h延长至40h左右,成功研制了治疗肝癌的含稀土元素的放射性玻璃微球;建立了超热辐射照管和计算机控制的循环跑兔装置,扩展了微堆活化分析范围和领域;研制出一种新颖、简单、准确,且无需添置任何设备的测量堆芯绝对中子通量密度的方法——氙中毒法. 尽管深大微堆具有固有的安全性,但它目前处于运行后期. 因腐蚀、疲劳等原因,核燃料元件包壳破损的可能性将越来越大,为此研制了安全监测计算机系统,一旦发生核燃料元件包壳破损时,系统能很快监测放射性泄漏,这对控制核污染起到十分重要的作用. 但这并不说明深大微堆已安全无事. 国外发生的一系列核泄漏事件昭示人们,在核安全管理中,人员因素至关重要. 不管放射性物质泄漏多与少,影响都很大,万万不能麻痹大意.
Abstract:
Progresses of the Miniature Neutron Source Reactor(MNSR) in Joint Institute of Applied Nuclear Technology in Shenzhen University are introduced in this paper. The following main issues are concluded: ① The continuous safety operating time is increased from 6-8 hours to 40 hours by special measures. This important progress opens the future of producing radioactive isotopes of micro-sphere containing rare-earth element 166Ho which can cure liver cancer and has been obtained in MNSR; ② The superheat rabbit device and cycle rabbit device controlled by computer has been established. That extends the scope of activation analysis; ③ A new, simple and accurate method, xenon poisoning method, measuring absolute neutron flux has been developed; ④ A system to check the radioactive release from the reactor by computerized devices has been set up.
