介绍深圳大学核技术所几年来对微型反应堆（ 简称微堆） 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； 研究成功一种新颖、简单、准确， 又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． 由于腐蚀、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． 但应指出， 这并不是说深大微堆已安全无事．由最近国外发生的一系列核泄漏事故说明， 核安全管理、人员因素至关重要． 不管放射性物质泄漏多少， 影响都很大， 万万不能麻痹大意．
Introduced a series of improvements made by the Institute of Nuclear Technology of Shenzhen University over the past few years to the microreactor (referred to as micro-reactor), including: taking special measures to extend the safe operation time of microreeds, extending from the original 6 ~ 8h to about 40h; successfully developed the treatment Liver cancer rare earth-containing radioactive glass microspheres; established a hyperpyretic tube and computer-controlled circulation run rabbit device, extending the scope and field of micro-reactor activation analysis; a successful, novel, simple, accurate, and without the need to purchase Method for measuring absolute core neutron flux density of any equipment - xenon poisoning method. Although deep micro-heap with inherent security, but it is currently in operation. Due to corrosion, fatigue and other reasons, nuclear fuel components will be more and more likely to break the cladding. Therefore, a safety monitoring computer system has been developed to detect radioactive leaks quickly in the event of nuclear fuel component cladding failure. Nuclear pollution plays a very important role. However, it should be pointed out that this does not mean that the deep micro-heap is safe and sound. A series of nuclear leaks that took place recently abroad shows that nuclear safety management and personnel factors are of the utmost importance. Regardless of the amount of radioactive material leakage, the impact is great, must not be careless.
