Current fission-based methods of ⁹⁹Mo production require single use uranium targets which leads to spent uranium waste. This waste could be reduced if a target is developed that does not require dissolution so that it can be reused for multiple production runs. MCNP6.2 was used to model reusable targets of 20% and 1% enrichment for activity produced, target efficiency and burnup. The 1% enriched target was found to be much more efficient but had a lower activity produced compared to the 20% enriched target. The ideal target design for ⁹⁹Mo production that optimises efficiency and reusability and reduces the self-shielding effect of UO₂ was found to be a target that is made from 1% enriched UO₂ with density as high as allowable for sufficient yields, efficient ⁹⁹Mo extraction and having an irradiation time of 5 days, with the target able to be re-irradiated and re-processed 2–4 times.

当前基于裂变的⁹⁹ Mo 生产方法需要一次性使用的铀靶，这会导致废铀废物。如果开发的靶材不需要溶解，从而可以重复用于多次生产运行，则可以减少这种浪费。MCNP6.2 用于模拟 20% 和 1% 富集的可重用目标，用于产生的活动、目标效率和燃耗。发现与 20% 富集的目标相比，1% 富集的目标效率更高，但产生的活性较低。发现优化效率和可重复使用性并降低 UO ₂自屏蔽效应的⁹⁹ Mo 生产的理想靶材设计是由 1% 富集的 UO ₂制成的靶材密度达到足够高的产量，高效提取⁹⁹ Mo，辐照时间为 5 天，靶材可以再辐照和再加工 2-4 次。
