Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On December 22nd, China’s first domestically developed boron recovery system (TEP) steam compressor for third-generation pressurized water reactor nuclear power plants, the “Hualong One”, was officially produced and shipped out by Shandong Zhangqiu Blower Co., Ltd. The official debut of this equipment not only marks a crucial step forward in the localization of key nuclear power equipment in our country, but also serves as an important node in the restructuring of the global nuclear power equipment supply chain, drawing widespread attention from within and outside the industry. The TEP steam compressor is the core equipment in a nuclear power plant’s boron recovery system; it is required to deliver boron-containing radioactive steam in a stable manner over a long period of time, which imposes extremely stringent technical requirements. Previously, this equipment relied for a long time on foreign suppliers such as those in Germany; its high cost and long maintenance periods posed a major obstacle to the autonomous development of nuclear power in our country. Since 2021, Shandong Zhanggu has been working together with China General Nuclear Power Group Co., Ltd. to carry out research and development; by leveraging the Hualong One nuclear power technology, they have developed the first domestically produced TEP steam compressor. This device features a Roots-type design, offering excellent sealing performance, stable operation, a service life of up to 60 years, and the ability to undergo over 60,000 start-ups. Its key performance indicators such as compression ratio and energy efficiency rate are at the international advanced level. It has been evaluated positively by the China Machinery Industry Federation and the China General Machinery Industry Association, which noted that it fills a gap in domestic technology.
