研究了通过轻核素诱发的火花使长寿命裂变产物嬗变的情况，目的是确定这种方法在经济和环境方面对长寿命裂变产物的可行性。横截面数据来自TAPIS评估核数据库（TENDL）。采用厚靶模型研究了嬗变过程中靶同位素的消耗。嬗变产额是使用中国主动加速器驱动系统可用的最高光束强度计算的。结果表明，轻核素诱发的放射性反应能显著降低所研究的长寿命裂变产物的放射性毒性。使用由元素LLFP制成的嬗变靶和强度为5 mA的质子束，Sr-90、Zr-93、Pd-107或Cs-137的消耗量可达到每年约500 g。
The transmutation of long-lived fission products through spallation induced by light nuclides was investigated for the purpose of determining the feasibility of this approach for long-lived fission products, in both economic and environmental terms. The cross-section data were obtained from the TALYS Evaluated Nuclear Data Library (TENDL). A thick target model was used to study the consumption of the target isotopes in the transmutation process. The transmutation yield was calculated using the highest beam intensity available with the China initiative accelerator-driven system. It was found that the light nuclide-induced spallation reaction can significantly reduce the radio toxicity of the investigated long-lived fission products. Using the transmutation target made of elemental LLFP and the proton beam with an intensity of 5 mA, the consumption of Sr-90, Zr-93, Pd-107, or Cs-137 can reach approximately 500 g per year.
