关于PWR及CANDU堆先进燃料管理策略的研究

阐述开展先进燃料管理策略研究的必要性与紧迫性。对我国秦山核电厂的燃料管理策略的改进进行了初步探讨，包括提高富集度延长循环长度、增大平均卸料燃耗、应用先进可靠毒物和低泄漏优化换料、改进燃料组件设计和适当提高功率等，并对可能取得的重大经济效益进行了讨论。提出研究ＰＷＲ的乏燃料在ＣＮＡＤＵ堆中应用及形成ＰＷＲ／ＣＡＮＤＵ联合燃料循环的可行性，以提高燃耗深度，增加能量输出，降低发电成本。

Study of Advanced In-Core Fuel Management Strategy for PWR and CANDU Nuclear Power Plants

This paper summarizes the preliminary study on improving the in core fuel management strategy of Qinshan PWR Nuclear Power Plant,including the extended cycle length,higher discharge bur nup,application of advanced burnable poisons and low leakage loading pattern,improvement of assembly design and uprating of thermal power.The possible benefit and efficiency in economics are discussed.The feasibility of using the spent PWR fuel in CANDU and an advanced fuel cycle of PWR/CANDU Synergism are described,which is of great economical and practical significance for the countries possessing both of the PWR and CANDU nuclear power plants.
