摘要

一些提供核研究反应堆的燃料厂需要提高生产能力,以满足对这类核燃料日益增长的需求。这些工厂的生产能力扩大后,将需要管理新的生产水平。这个级别通常是工业级别,这对管理人员构成了挑战。这些挑战来自这样一个事实,即其中一些工厂目前是在实验室的基础上运行的,并且没有库存。工业生产节奏的变化要求在计划和控制方面采取新的行动。基于UF6水解的生产工艺并不是常用的核燃料生产工艺。该生产路线上燃料生产的工业水平的生产计划和控制是一个新的研究领域。本文的方法是建立一个成本最小化的数学线性模型。我们还对模型进行了敏感性分析。结果有助于在不同的生产方案中最小化成本,并显示库存的需求。数学模型是动态的,因此如果每月执行一次,结果会更好。因此,管理小组将更清楚地了解成本以及新的、必要的生产和库存水平。

Studies on Production Planning of Dispersion Type U3Si2-Al Fuel in Plate-Type Fuel Elements for Nuclear Research Reactors
Several fuel plants that supply nuclear research reactors need to increase their production capacity in order to meet the growing demand for this kind of nuclear fuel. After the enlargement of the production capacity of such plants, there will be the need of managing the new production level. That level is usually the industrial one, which poses challenges to the managerial staff. Such challenges come from the fact that several of those plants operate today on a laboratorial basis and do not carry inventory. The change to the industrial production pace asks for new actions regarding planning and control. The production process based on the hydrolysis of UF6 is not a frequent production route for nuclear fuel. Production planning and control of the industrial level of fuel production on that production route is a new field of studies. The approach of the paper consists in the creation of a mathematical linear model for minimization of costs. We also carried out a sensitivity analysis of the model. The results help in minimizing costs in different production schemes and show the need of inventory. The mathematical model is dynamic, so that it issues better results if performed monthly. The management team will therefore have a clearer view of the costs and of the new, necessary production and inventory levels.
