某核电站乏燃料冷却系统出现腐蚀退化现象。制定了一项系统和全面的调查计划，以揭示退化的根本原因。进行了一系列的腐蚀试验、力学、显微组织和微生物研究。此外，还对操作条件和焊接参数进行了模拟。根据结果，确定了降解过程的主要贡献者，并提出了可能的降解机理。
Corrosion degradation was observed in a nuclear power plant spent fuel cooling system. A systematic and comprehensive investigation program was developed to reveal the root cause of the degradation. Series of corrosion tests, mechanical, microstructural and microbiological investigations were carried out. Also, simulations of the operating conditions and welding parameters were performed. Based on the results, the major contributors to the degradation process were identified and a possible degradation mechanism was proposed.
