摘要
研究型反应堆在放射性同位素的生产中发挥了至关重要的作用。中国原子能科学研究院正在进行新型多功能泳池式研究堆(492-2)的设计,该堆可以承担放射性同位素生产任务。本文利用蒙卡程序MCNP6(Monte Carlo N-particle 6)对492-2的辐照能力进行了分析,介绍了适宜在492-2上生产的同位素的特性及生产制备方式,同时为验证492-2堆辐照生产放射性同位素的可行性,利用SCALE6.1程序对辐照生产^(131)I、^(177)Lu和^(90)Y同位素的产量和比活度进行了理论计算。计算结果表明,利用492-2堆可以生产高比活度同位素。
Research reactors play a vital role in the production of radioisotopes.The China Institute of Atomic Energy is designing a new multifunctional pool-type research reactor(492-2),which can undertake radioisotope production tasks.In this paper,the irradiation capacity of 492-2 was analyzed by using the Monte Carlo N-particle 6 program(Monte Carlo N-particle 6),the characteristics and production methods of isotopes suitable for production on 492-2 were introduced,and in order to verify the feasibility of producing radioisotopes by irradiation of 492-2 reactor,the production of isotopes of 131I,177Lu and 90Y was theoretically calculated by SCALE6.1 program,and parameters such as yield and specific activity were obtained.The theoretical calculation results show that high specific activity isotopes can be produced by using the 492-2 reactor.
