EU-APR Safety Features Reflecting Recent European Requirements

The redundancy design of safety systems, the diversity design of safety functions, and the dedicated mitigation systems for severe accidents were taken into account to resolve the differences between licensing approaches in Korea and the Europe. Also, new safety issues on the extreme external hazards were implemented in the plant design. Finally, the EU-APR achieved a high level of compliance with the EUR and certified by the EUR organization in November 2017. In this paper, its design modifications from the APR1400 are presented with emphasis on the safety features. The EU-APR is a 1400 MWe Gen III+ reactor intended for European market. We derived the refined DiD approach, reinforced failure criteria for safety features, protection against CCF, SA dedicated mitigation systems, the aircraft crash protection, and countermeasures against Fukushima accident to cope with the safety issues with European approach so that the EU-APR will be licensed in any of the European countries with minimum changes.
