我国压水堆装载MOX燃料对核燃料循环情景影响初步分析

Primary analysis of PWR loaded with MOX fuel and related fuel cycle scenarios in China

为了满足持续增长的国家能源需求,核电将有更大规模的发展。本文对我国未来的核电发展和核燃料循环进行了情景研究,预测了2050年前核电对天然铀资源和燃料制造能力的需求情况,核电站产生的乏燃料量,分离钚产生量。乏燃料后处理能力作为我国核燃料循环体系的重要组成部分,将对我国核燃料循环情景产生重要影响。本文对后处理规模和分离钚的利用进行了假设,研究了两种情景模式下后处理和分离钚利用对我国铀资源需求和核废物产生的影响。

To meet the China＇s energy demand, nuclear power will keep growing in the future. Nuclear fuel cycle system is essential for the nuclear power development in China. In this paper, nuclear fuel cycle issues, including the amount of natural uranium resource, separation work and nuclear fuel for PWR NPP, together with spent fuel and separated plutonium are studied. The influences of spent fuel reprocessing and separated plutonium recycling on the uranium resource demand and accumulation are discussed intwo fuel cycle scenarios.
