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
Stage 32013 - 2015
  • Optimal design to improve economic feasibility and safety
  • Evaluation on business profitability of construction and entering overseas markets
