摘　　要：基于^(62)Ni(n,γ)^(63)Ni制备放射性同位素^(63)Ni的原理,将中国实验快堆(CEFR)作为辐照平台,设计了高富集^(62)Ni靶件。采用MCNP和SCALE6.1作为计算程序,研究在CEFR上生产同位素^(63)Ni的可行性。计算结果表明,将堆芯反射侧层区域位置2作为辐照位置,并将靶件内部设计为具有良好慢化性能的氢化锆慢化剂,经满功率运行辐照8年以上,理论上CEFR具备生产高比活度^(63)Ni同位素的可行性,但综合考虑CEFR现实因素,认为CEFR生产^(63)Ni同位素不具有良好的经济性、时效性和现实的可行性。Based on the principle of^(62)Ni(n,γ)^(63)Ni preparing radioactive isotope^(63)Ni,using the China Experimental Fast Reactor(CEFR)as an irradiation platform and design a high enrichment^(62)Ni target.Using MCNP and SCALE6.1 calculation codes,study and analyze the feasibility of producing isotope^(63)Ni on CEFR.The calculation results show that by using position 2 on the reflection side of the core as the irradiation position and designing the target as a ZrH moderator with good moderating performance,and operating at full power for more than 8 years,CEFR theoretically has the feasibility of producing high specific activity^(63)Ni isotopes.However,considering the practical factors of CEFR,it is believed that CEFR’s production of^(63)Ni isotopes does not have good economic,timeliness,and practical feasibility.
