Abstract
The Advanced PWR reactor class was designed by Mitsubishi Heavy Industries (MHI) through an evolutionary approach involving steady improvements implemented through the construction of 24 nuclear power plants over a 45 year period. Conceptually based on the Advanced PWR, the EU-APWR is a reactor intended for the European market whose design was adapted to achieve compliance with the European Utility Requirements (EUR) and the Finnish regulatory guides on nuclear safety (YVL). This paper describes how the EU-APWR design evolved to be EUR compliant, as certified in 2014.
