ATMEA1

ATMEA1 is a type of pressurized water reactor (PWR) designed by ATMEA, a joint venture between Areva NP and Mitsubishi Heavy Industries (MHI). The ATMEA1 reactor is designed for use in nuclear power plants to generate electricity.

Design

The ATMEA1 reactor is a Generation III+ PWR, which means it incorporates advanced safety features and has a high level of performance. The reactor has a net electrical output of 1,100 MWe and a thermal output of 3,150 MWth. It is designed to operate for 60 years and has a 24-month fuel cycle.

The reactor's design includes several safety features, such as a core catcher to contain the nuclear fuel in the event of a severe accident, and a passive cooling system that can operate without external power or human intervention.

Development

The development of the ATMEA1 reactor began in 2006 when Areva NP and MHI formed the ATMEA joint venture. The reactor design was completed in 2011, and in 2012, the Canadian Nuclear Safety Commission (CNSC) accepted the ATMEA1 for a vendor design review.

Applications

The ATMEA1 reactor is suitable for use in new nuclear power plants or as a replacement for older reactors. It can be used in a range of site conditions, including areas with high seismic activity or limited water availability.
