摘要
腐蚀产物在压水堆(Pressurized Water Reactor,PWR)燃料表面沉积后形成的污垢(Chalk Rivers Unidentified Deposits,CRUD)会对反应堆安全性和经济性造成影响。直接检测燃料污垢存在诸多客观条件限制,且目前尚未对PWR燃料污垢行为开展系统研究。本文阐明了PWR运行数据与燃料污垢行为之间的关系,提出了一种适用于PWR的燃料污垢行为分析方法,并对某PWR连续循环开展了燃料污垢行为分析。结果表明,本文提出的分析方法能够较真实反映PWR燃料污垢水平,研究成果可为PWR在运机组开展燃料污垢行为分析提供参考。
The corrosion products may deposit on fuel surface and form CRUD,which makes impact on the safety and economics of reactor core.Direct measurement of fuel CRUD is restricted by multiple objective conditions,and the systematic study of PWR fuel CRUD behavior has not been conducted in domestic and foreign regions.This article clarifies the correlation between PWR operating data and fuel CRUD behavior,proposes a fuel CRUD behavior analysis methodology and applies the methodology on a PWR consecutive cycles.Results show that the methodology is able to reflect the true level of PWR fuel CRUD,and could provide reference for fuel CRUD behavior analysis of operating PWRs.
