The advanced boiling water reactor (ABWR) is a Generation III boiling water reactor. The ABWR is currently offered by GE Hitachi Nuclear Energy (GEH) and Toshiba. The ABWR generates electrical power by using steam to power a turbine connected to a generator; the steam is boiled from water using heat generated by fission reactions within nuclear fuel. Kashiwazaki-Kariwa unit 6 is considered the first Generation III reactor in the world.

Nuclear power in Taiwan accounts for 2,945 MWe of capacity by means of 1 active plant and 2 reactors. In 2015, before the closure of 3 reactors, they made up around 8.1% of its national primary energy consumption, and 19% of its electricity generation. The technology chosen for the reactors has been General Electric BWR technology for 2 plants and Westinghouse PWR technology for the Maanshan Nuclear Power Plant. Construction of the Lungmen Nuclear Power Plant using the ABWR design has encountered public opposition and a host of delays, and in April 2014 the government decided to suspend construction.
