China plans 60 MWE modular nuclear reactor by 2020 and a floating reactor by 2025

China General Nuclear (CGN) expects to complete construction of a demonstration small modular offshore multi-purpose reactor by 2020, the company announced yesterday.

CGN said development of its ACPR50S reactor design had recently been approved by China’s National Development and Reform Commission as part of the 13th Five-Year Plan for innovative energy technologies.

The company said it is currently carrying out preliminary design work for a demonstration ACPR50S project. Construction of the first floating reactor is expected to start next year, it said, with electricity generation to begin in 2020.

The 200 MWt (60 MWe) reactor has been developed for the supply of electricity, heat and desalination and could be used on islands or in coastal areas, or for offshore oil and gas exploration, according to CGN.

CGN promotes the advantages of a small modular marine reactor

ACPR SMR: Safe, Flexible, Efficient Advanced Small Pressurized Water Reactor

Multi-purpose Small Pressurized Water Reactor independently developed by CGN;
Adopting advanced safety design concepts, satisfying safety requirements for eliminating off-site emergency;
To be used in small-scale grid, comprehensive supply of heat, electricity, water and steam and marine energy.
ACPR50S: Marine Small Modular Reactor

Mature technology: compact reactor design, combined with mature marine engineering technologies
High safety level: combination of active and passive safety systems, to make use of the advantage of sea water in cooling and shielding
Economical and Practical: adopting long-cycle refueling scheme to be more competitive than conventional marine energy; it could be used as a comprehensive energy make-up station for marine exploitation and to satisfy demand for electricity, heat, water and steam in marine environment.

The Chinese company said it is also working on the ACPR100 small reactor for use on land. This reactor will have an output of some 450 MWt (140 MWe) and would be suitable for providing power to large-scale industrial parks or to remote mountainous areas.
