Lifetime and ageing management of nuclear power plants: A brief overview of some light water reactor component ageing degradation problems and ways of mitigation

The susceptibility and tendency for nuclear power plant (NPP) components to undergo changes in their mechanical and physical properties in the course of the NPP lifetime is generally termed as “ageing”. The light water reactor (LWR) nuclear environment is not a begnign one; it is characterized not only by fast neutrons, which can degrade metallic structures, but also relatively high temperatures of coolant water (around 300°C) which may contain impurities (e.g. sulphate, chloride, peroxides) which can cause corrosion. The hydrodynamical conditions of the coolant in steam generators, for example, can cause thermal fatigue, erosion and corrosion; suspended particulate matter can accelerate erosion processes which can lead to wall thinning and lowering of safety margins. Ageing is, therefore, a very complex mixture of factors concerned with materials, temperatures, times of exposure to environments which vary with time and with respect to chemical composition and flow charactertistics.

The paper describes a few ageing phenomena which can be considered important due to their impact on nuclear safety issues; their influence on economic aspects (availability) of NPP is outlined. Mitigation measures for NPP component ageing problems are given together with recommendations for addressing such issues in NPP now and in the future.     

蓖麻油酸二乙醇胺硼酸酯合成工艺及摩擦性能

为开发环境友好型润滑油添加剂，以蓖麻油酸、二乙醇胺为原料，采用两步合成法制备蓖麻油酸二乙醇酰胺（RA），然后与硼酸合成蓖麻油酸二乙醇酰胺硼酸酯（RAB）。利用FTIR对RA及RAB的结构进行表征，并以菜籽油为基础油，考察RAB的摩擦学性能。通过单因素实验得到合成RA的最佳条件为：酰化反应中蓖麻油酸和二乙醇胺物质的量比为1.0：0.8，150 ℃下反应6 h；胺解反应中蓖麻油酸和二乙醇胺物质的量比为1.0：0.4，催化剂氢氧化钠用量为蓖麻油酸和二乙醇胺总质量的1%，95 ℃下反应3 h，RA产率达88.10%；RAB的最佳合成条件为：RA与硼酸物质的量比为1.8：1.0，催化剂对甲苯磺酸用量为RA和硼酸总质量的1.5%，140 ℃下反应100 min，RAB产率达92.78%。添加RAB的菜籽油在摩擦表面形成含B、N的复合润滑保护膜，当RAB添加量为菜籽油总质量的2%时，油样最大无卡咬负荷（PB）相比菜籽油提高了61%；当RAB添加量为1%时，油样表现出良好的摩擦保护性能。

含磷本质阻燃环氧树脂的研究进展

综述了含磷本质阻燃环氧树脂(包括含磷协同本质阻燃体系)的发展、现状和未来趋势。与添加型阻燃剂阻燃环氧树脂相比,通过含磷环氧化合物和/或含磷固化剂把磷元素嵌入环氧树脂结构中制得的含磷本质阻燃环氧树脂,具有阻燃效率高、阻燃持久、物理力学性能不受影响、燃烧过程中毒性腐蚀性挥发物质的生成量低等优势。利用协同阻燃效应,可以进一步提高阻燃性能。但是,含磷本质阻燃环氧树脂和含磷协同本质阻燃体系存在制备工艺复杂、生产成本较高等不足。     

Effect of amide type modified rapeseed oil as lubricating additive on friction and wear behavior of steel-steel and steel-aluminum alloy systems

A new type of environmentally friendly lube additive-amide type modified rapeseed oil was synthesized and characterized by infrared spectrum. Its effect on the friction and wear behavior of steel-steel and steel-aluminum alloy systems were investigated with a four-ball machine and an Optimol SRV friction and wear tester respectively.The morphographies of the worn surfaces were analyzed by means of scanning electron microscopy(SEM). The worn surfaces of the 2024Al alloy block were analyzed by means of X-ray photoelectron spectroscopy(XPS). The results show that the modified rapeseed oil as additives can obviously decrease the wear rate and friction coefficient of steel pair and steel-aluminum frictional pair. Its lubrication mechanism is inferred that a high strength complex protection films form on the worn surface of the Al alloy due to the adsorption or tribochemistry reaction of a long chain additive molecule and high reaction activity of N element.
