An economic and mathematical model has been developed to determine the competitiveness of REMIX-A and -C uranium-plutonium fuel obtained by reprocessing spent fuel from thermal reactors. The presented model makes it possible to calculate the cost metrics of nuclear fuel components and the fuel component of the cost of NPP electricity as a function of the cost metrics of key process changeovers. It is shown that as the market quotations for natural uranium and separation work increase, REMIX fuel becomes more competitive and, more importantly, all the more significant, the lower the cost of reprocessing spent fuel. However, even with zero cost of reprocessing the gain from the introduction of REMIX fuel does not exceed 25%. At the same time, its use allows a 20-fold reduction in the mass of radioactive waste going to final disposal, 24% (REMIX-A) to 36% (REMIX-C) savings of natural uranium, and 8–18% of separation work (REMIX-A) as well as 18% (REMIX-A) to 40% (REMIX-C) reduction in the accumulation of depleted uranium hexafluoride.

已经开发了一个经济和数学模型来确定通过后处理来自热反应堆的乏燃料获得的 REMIX-A 和 -C 铀钚燃料的竞争力。所提出的模型使计算核燃料组件的成本指标和核电厂电力成本的燃料组件成为可能，作为关键过程转换的成本指标的函数。结果表明，随着天然铀和分离工作市场报价的增加，REMIX 燃料变得更具竞争力，更重要的是，乏燃料后处理成本越低越显着。然而，即使后处理成本为零，引入 REMIX 燃料的收益也不超过 25%。同时，它的使用可使最终处置的放射性废物质量减少 20 倍，
