Chemistry and corrosion in nuclear and coventional power system coolants

这里描述的研究是该项目的发展，该项目始于1992年，当时是新不伦瑞克大学的NSERC工业研究教授。该项目基于电力系统冷却剂技术，主要但不完全是核能，研究小组专注于水路的化学和腐蚀。在高温高压下运行的实验回路最初是由该小组在北卡罗来纳大学化工系的实验室设计和建造的，此后一直在全职使用(经过一些改进和特别修改)。这项研究增进了对腐蚀和材料运输的了解，并解决了迫在眉睫的工业问题，如：系统材料的腐蚀(导致化石工厂和核电站的给水管道破裂，导致工作人员死亡)；蒸汽发生器和其他热交换器被腐蚀产物污染(这降低了效率，促进了腐蚀)；核反应堆初级冷却剂中的材料运输(导致堆芯和其他部件结垢，增加辐射场和工人的辐射剂量)。该小组计划中的一个补充项目开发了一种新的铀加工流程图，该流程图承诺减少CANDU燃料生产中的成本和浪费。来自行业的持续支持证明了该计划的相关性，以前来自AECL和NB Power，他们为最初的IRC提供资金，最近来自CANDU Owners Group(COG)，特别是NB Power、OPG和Bruce Power。该集团的活动应继续吸引电力研究所(EPRI)等组织的研究合同，该研究所自成立以来一直为该集团的项目提供资金，并在过去几年继续签订了五份主要合同。

The research described here is a development of the program that began as an NSERC Industrial Research Chair at the University of New Brunswick in 1992. That program was based on the technology of power system coolants, mainly but not exclusively nuclear, and the research group concentrated on the chemistry and corrosion of water circuits. Experimental loops to operate at high temperature and high pressure were originally designed and built by the group in laboratories in the Chemical Engineering Department at UNB, and have been used (with some improvements and ad hoc modifications) full-time ever since. The research improves understanding of corrosion and material transport and addresses immediate industrial problems such as: corrosion of system materials (which has ruptured feedwater pipes and killed staff in fossil and nuclear plants); fouling of steam generators and other heat exchangers with corrosion products (which reduces efficiency and promotes corrosion); and, material transport in nuclear reactor primary coolants (which leads to fouling in the core and other components and increases radiation fields and worker radiation dose). A complementary project within the group's program develops a novel flow sheet for processing uranium, which promises to reduce costs and waste in the production of CANDU fuel. Continuing support from industry attests to the relevance of the program, formerly from AECL and NB Power who funded the original IRC and latterly from the CANDU Owners Group (COG), specifically NB Power, OPG and Bruce Power. The activities of the group should continue to attract research contracts from organisations such as the Electric Power Research Institute (EPRI), which has funded projects with the group since its inception and has continued with five major contracts over the last few years.
