The U.S. nuclear power standards are based on original technologies, forming a comprehensive system that emphasizes professionalism and covers a wide range of categories. This system is adaptable to the development of various technologies and fully meets the requirements for nuclear power welding. It has been widely adopted across the United States, North America, Asia, and some European countries.
Inspired by American standards, France developed its own design and construction standards for pressurized water reactor nuclear islands, known as the RCC-M standard. This standard focuses on engineering design and construction, featuring a simple structure, limited application scope, and strong operational efficiency. The RCC-M standard has evolved from the 1993 version to the 2010 edition. After the 2007 version, the original French NF standards were gradually replaced by more universal EN or AWS standards, which are considered more reasonable and practical in real-world applications.
China has also established a set of welding-related standards for its nuclear power industry. These include administrative regulations such as the "Nuclear Power Plant Quality Assurance Safety Regulations HAF003," which is mandatory. There are also supplementary guidance documents like "Nuclear Power Plant Quality Assurance Safety Guide HAD003/01-10." Additionally, technical documents such as HAF J0011~J0014, F0045, HAFt5007, and J0048 provide detailed nuclear safety guidelines.
Other reference documents include the "Civil Nuclear Safety Equipment Welder Welding Operator Qualification Management Regulations" (HAF603), the "Welding Procedures for Nuclear Island Machinery and Equipment of Pressurized Water Reactor Nuclear Power Plants" (EJ/T1027.1~19), and the "Qualification Examination Rules for Welders for Civil Nuclear Pressure Equipment" (DL/T833-2003). In addition, general welding standards such as GB, NB, and JB play an important role in supporting the welding processes within China's nuclear sector.
CSA cement is considered as calcium sulphate aluminium cement. It shows the performance of high strength, rapid hardening or fast setting, corrosion resistance and carbonation resistance. It can be used in many fast setting applications such as non-shrink grout, self-leveling compound, fast setting tile adhesive or tile grout and fast setting repair system etc.
