Development Purpose
- Overall goal: To develop a domestic reactor that can compete with foreign GEN III+ reactors
- Safety level: 10 times higher than the APR1400 reactor
- Economic feasibility: 10% better than the APR1400 reactor (construction period: 36 months(F/C-F/L))
Goals of each stage in developing APR+ technology
- Stage 12007 - 2009
-
- Pre-evaluation on technological feasibility and establishment of development strategy
- Development of basic core technology
- passive safety facility
- complex module
- Development of APR+ standard design
- Stage 22010 - 2012
-
- Development of basic core technology
- complex module
- reevaluate APR+ standard design
- Development of APR+ standard design
- detailed design at the level of FOAKE (first of a kind engineering)
- Evaluation of APR+ safety and approval of standard design
- Development of basic core technology
- Stage 32013 - 2015
-
- Optimal design to improve economic feasibility and safety
- Evaluation on business profitability of construction and entering overseas markets
