Improvement of periodic inspection system by strengthening DiD using PSA results

1. Background
2. Objective
  • Re-definition of detailed items of the current periodic inspection in a perspective of Defense-in-Depth(DiD)
  • Development of an inspection methodology based on the risk concept of Probabilistic Safety Assessment(PSA)
  • Establishment of a periodic inspection system that can be converted from deterministic inspection to accident scenario-based inspection according to major events of PSA

Current status of research on improving periodic inspection system by strengthening Did using PSA results

  • Consultation on the application of nuclear regulatory safety standards
  • Research on the improvement of the continuous operation system of NPPs
  • Development of guidelines for preparing safety analysis reports for LWR
  • Consultation with Northease Asia International Nuclear Safety Cooperation
  • Research on nuclear safety culture
  • Development of guidelines for classification of NPP materials, etc.

Development of HRA methodology in digital MCR for regulatory verification

1. Background
  • Digital Main Control Rooms(MCR) are being introduced in NPPs, starting with APR1400
  • The existing analog MCR-based Human Reliability Analysis(HRA) failed to simulate the digital environment, resulting in poor reliability results
2. Objective
  • Development of a digital MCR-based HRA methodology based on the latest cognitive engineering theory
  • Derivation of human error factors(diagnostic and performance errors) and performance impact factors caused in the digital MCR environment
  • Development of a human error database for HRA performance
