1. OEF Program in Korea
E t R ti (MEST N ti 2009 37)Event Reporting (MEST Notice 2009-37)Reactor SCRAM (automatic, manual), ESF Actuation, Radioactive material release, External events (fire, earthquake, ..), etc.
• Safety-related equipment failure (TS LCO entry) is also reported by the utility
Corrective Actions imposed by the official letter of MEST/KINSManages the Lessons-learned (corrective actions) efficiently and effectively using the IT based System (CATS : Corrective Actions Tracking System)g y )
Safety Issues & Experiences of Safety Review &Inspection for NPP
Resolving in each regulatory project on safety issues under development of IT based Systematic Feedback Process

under development of IT based Systematic Feedback Process• Currently Safety Issues are managed & evaluated by 8 Expert Groups
(Mechanial, Electrical, Radioactive, Reactor ..)

Annual National Workshop on OEF
Workshop on OEF has been held for 7 yearsP ti i ti f MEST KINS li i d t i d thParticipation of MEST, KINS, licensee, industries and othersMajor discussions about
Optimization of the immediate response for NPP EventsConsistent and Reasonable Evaluation for the eventsConsistent and Reasonable Evaluation for the eventsmore exchange of information

4. Recent Activities for OEF
International activities for OEF information exchangeRCOP-1
to improve nuclear safety by feedback operating experiences of NPP in Northeastto improve nuclear safety by feedback operating experiences of NPP in Northeast Asia
IAEA ANSNl d h l f i f i i i d k l d dto analyze and share nuclear safety information existing and new knowledge and
practical experience among the countiesto construct a complete Asian network for sharing safety information
