The Novelty (What)

创新性（主要内容）

In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of "Single Energy Interval Value (SEIV)" and "Energy Spectrum Total Value (ESTV)", which significantly improved the production efficiency of isotopes such as ²⁵²Cf (by 15.08 times), ²⁴⁴Cm (by 65.20 times), ²⁴²Cm (by 11.98 times), and ²³⁸Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.

这项研究开发了一种新型快速诊断方法，用于优化基于超高通量反应堆产生超钚同位素的辐照方案。所提出的方法基于"能群价值（SEIV）"和"能谱总价值（ESTV）"的概念，显著提高了诸如²⁵²Cf（15.08倍）、²⁴⁴Cm（65.20倍）、²⁴²Cm（11.98倍）和²³⁸Pu（7.41倍）等同位素的生产效率。作为一种替代传统蒙卡燃耗计算方法的有效选择，这种方法为评估辐照方案和优化设计参数提供了一种更高效的途径。该研究为进一步完善超钚同位素生产分析提供了理论依据，从而实现更高效、可持续的生产方法。未来的研究将专注于能谱转换技术的实施，以进一步提高最佳能谱。

The Background (Why)

研究背景（主要原因）

The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as ²⁵²Cf, ²⁴⁴Cm, ²⁴²Cm, and ²³⁸Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.

超钚同位素在军事和航天技术等众多领域至关重要。尽管通过超高通量反应堆生产，但超钚同位素的生产仍然效率不高。过去关于通过超高通量反应堆优化超钚同位素生产的研究受到传统方法（如蒙卡燃耗计算）计算复杂性的限制。这些限制阻碍了辐照方案评估、筛选和优化。因此，本研究旨在开发一种快速诊断方法来评估辐射方案，以提高²⁵²Cf, ²⁴⁴Cm, ²⁴²Cm和²³⁸Pu等同位素的生产效率。研究结果表明，这种方法在推进超钚同位素生产方面具有很大潜力，这些同位素在军事、能源和航天技术等领域有着广泛的应用。
