The upper containment cylinder of the world's first commercial onshore small modular reactor (SMR), the Linglong One, was successfully installed on July 6 at Changjiang Nuclear Power Plant in South China's Hainan province.

The upper cylinder is an important component in ensuring the safety of the reactor building, and its installation lays a solid foundation for advancing the Linglong One demonstration project.

The Linglong One, also known as the ACP100, is a multi-purpose pressurized water reactor (PWR) design developed by the China National Nuclear Corporation (CNNC) with independent intellectual property rights. It is the world's first third-generation SMR to pass a safety review by the International Atomic Energy Agency (IAEA).
