In July 2005, the company formally signed a contract for four circulating water pumps for nuclear power projects and delivered them on schedule within two years.

In April 2006, the company signed a supply contract for 26 conventional island pumps from Lingao Phase 2 of Daya Bay Nuclear Power Station and signed a supply agreement for 52 pumps for follow-up projects. This is the first project of the first conventional island BOP system in China's 900,000 kilowatts nuclear power plant. It also marks the long advancement of Hunan Electric Power Co., Ltd. into the field of nuclear power equipment.

In order to further enhance the company's competitive strength in the field of nuclear power equipment, in April 2007, Hunan Fossa Hunan Long Pump Pump Co., Ltd. was established by a joint venture between Hunan Xiangdian Long Pump and American Flowserve. Since then, Xiangdian Long Pump has rapidly moved to the forefront of China's nuclear power equipment R&D and manufacturing. In November 2007, the Consortium won the supply contract for eight large-scale concrete scroll pumps in the No. 1 and No. 2 projects of China Guangdong Nuclear Power Hongyanhe 1000MW nuclear power plant. Then, they successively tendered for the No. 1 and No. 2 units of Ningde, No. 3 and No. 4 units of Ningde, the Shidao Bay nuclear power transformation project, and the No. 3, No. 4, No. 5 and No. 6 units of Yangjiang Nuclear Power Phase I project. Repeatedly won the bid.

On July 15 this year, Xiangdian Long Pump won the bid for the AP1000 condensate pump for No. 1 and No. 2 units of the Taohuajiang Nuclear Power Plant and became the first domestic manufacturer of the condensate pump for the AP1000 nuclear power plant in China.

“Software and Hardness” enhances strength While developing products and its market at a large scale, Xiangdian Long Pump has vigorously promoted the soft and hard strength of nuclear power equipment manufacturing. In order to improve soft power, they focus on the nuclear culture of the company. The company's management system and "three things" in the culture of nuclear power (everything according to the procedure, all in writing, all speaking on the basis of data) and "four common things" (everything is ruled, all things can be followed, Everyone is responsible, everything is supervised) Fully connected. At the same time, the company has successively passed nuclear power companies such as China Nuclear Power, China Nuclear Power and other nuclear power companies, Qinshan, Tianwan, and Taohuajiang nuclear power sources, as well as third-party assessments from international companies such as French nuclear power, ALSTON, and the United States Flowserve. In August 2007, the company obtained nuclear II design and manufacturing qualification certification.

In order to enhance hard power, the company launched an overall relocation in 2006, and purchased 400 acres of land in the Ningxiang Economic Development Zone and Changsha Lugu High-tech Zone to build a new cast plate and machine-installed test plate.
