chengdu, september 14 (china news service) (liu zhongjun, he wei, li jin) on september 13, the completion ceremony of the forged pump casing of the first rcc-m standard hualong one main pump "made in china" was held at the deyang base of sinomach heavy equipment group co., ltd. (hereinafter referred to as "sinomach heavy equipment"). this project fills the gap in rcc-m standard forged pump casings and is another milestone achievement of sinomach heavy equipment in the field of nuclear island main equipment development.

it is understood that rcc-m is the abbreviation of france's "rules for the design and construction of mechanical equipment for pressurized water reactor nuclear islands". it was compiled by the french association for the design and construction of nuclear island equipment (afcen) to standardize the design and construction of mechanical equipment for french pressurized water reactor nuclear power plants and has been adopted by the french government.

since the second heavy equipment of sinomach heavy equipment co., ltd. undertook the task of developing the forged pump casing of the main pump of hualong one, it has relied on its profound technical accumulation, fully utilized its nuclear energy equipment development capabilities and advantages, and carried out project development work in accordance with the nuclear first-level quality assurance requirements. through lean control and precision manufacturing throughout the entire process, it has completed a number of technical breakthroughs and completed the project development work efficiently and on schedule. the product material performance, manufacturing process, reliability and safety have been highly evaluated.
