The initial pump, manufactured by Hainan Nuclear Power and Harbin Electric Equipment, was delivered to the site in March. CNNC stated: “Installation of the pump further demonstrates China’s comprehensive strength in the design of new nuclear energy systems, high-end equipment manufacturing and coordinated management of complex projects.”
Development of the Linglong One began in 2010, and in 2016, it became the first SMR to pass an independent safety assessment by International Atomic Energy Agency experts. The integrated pressurized water reactor design, finalized in 2014, incorporates 57 fuel assemblies and integral steam generators, derived from the larger ACP1000 reactor. Featuring passive safety systems, the design allows for potential underground installation.
CNNC officially launched the project in 2019, with approval from China’s State Council in 2021 for the ACP100 Science & Technology Demonstration Project. Construction started in July 2021 with the pouring of first concrete. The lower section of the containment shell was positioned in February 2022, and the final concrete for the nuclear island’s underground retaining walls was completed in August 2022. Upon completion, the reactor is expected to generate enough electricity to power 526,000 households.
The Changjiang site already hosts two operational CNP600 power units. Additionally, construction of two Hualong One power units began in March and December 2021, with operations planned by the end of 2026. The ACP100 project complements these efforts, showcasing advancements in compact, versatile nuclear technology.
The Linglong One’s multi-purpose design supports diverse energy needs, contributing to sustainable development in Hainan Province. Its passive safety features enhance operational reliability, while the use of domestically produced equipment highlights China’s capabilities in nuclear engineering and manufacturing.
The successful installation of the first pump marks a significant milestone in the project’s progress. As construction advances, the ACP100 is poised to demonstrate the potential of small modular reactors in meeting modern energy demands efficiently and sustainably.
