利用中国实验快堆生产放射性同位素的可行性研究

摘要

China Experimental Fast Reactor (CEFR) is used not only for all kinds of fuels and materials irradiation ,but also as a good platform for production of radioiso-topes .Irradiation performance of CEFR was described in this paper .The production and the specific activity of 32 P ,33 P ,35 S ,89 Sr ,14 C and 60 Co were obtained by calculation code .T he results show that high purity 32 P ,33 P and 35 S can be obtained in CEFR core , and none carrier 89Sr can be produced by fast neutron (n ,p) reaction .Meanwhile ,high specific activity 14 C and 60 Co can be produced in CEFR blanket by setting moderator .It is feasible to product these radioisotopes in CEFR .%中国实验快堆（CEFR）不仅能进行各种燃料、材料辐照实验，也是放射性同位素生产的优良平台。本文对CEFR的辐照性能进行了描述，并利用计算程序对适宜在CEFR上生产的同位素32 P、33 P、35 S、89 Sr、14 C、60 Co进行理论计算，得到了产量和比活度等参数。计算结果表明，在CEFR堆芯辐照可得到纯度极高的32 P、33 P、35 S ，利用快中子的（n ，p）反应可得到无载体的89 Sr ，在CEFR反射层布置慢化材料可得到比活度较高的14 C、60 Co。以上结果表明，在CEFR上生产同位素是可行的。
