APWR

APWR‏‎ or Advanced Pressurized Water Reactor is a type of nuclear reactor designed and manufactured by Mitsubishi Heavy Industries (MHI). It is a third-generation nuclear reactor design and is one of the most advanced and efficient types of pressurized water reactor (PWR) currently in operation.

Design and Operation

The APWR‏‎ design is based on the traditional PWR design, but incorporates several significant improvements and innovations. The reactor core is designed to operate at a higher temperature and pressure than traditional PWRs, which increases the efficiency of the steam turbine and reduces the amount of nuclear fuel required.

The APWR‏‎ also features advanced safety systems, including a passive cooling system that can operate without external power, and a core catcher designed to contain the meltdown of the reactor core in the event of a severe accident.

Deployment

The first APWR‏‎ units were commissioned in Japan in the 1990s, and the design has since been adopted by several other countries, including the United States and China. The largest APWR‏‎ plant in operation is the Oma Nuclear Power Plant in Japan, which has a capacity of 1,383 MW.

Future Developments

MHI is currently developing a larger version of the APWR‏‎, known as the APWR+‏‎, which will have a capacity of up to 1,700 MW. This design is intended to be even more efficient and safer than the current APWR‏‎ design.
