  • Short-term Action Plan
  • Emergency Preparedness and Response
    • Immediately after the Fukushima accident on March 11, 2011, a task force of senior KINS staff joined the emergency response actions under the direction of the Prime Minister's Office. The Ministry of Education and Science Technology (MEST), currently the Nuclear Safety and Security Commission (NSSC), and the Korea Institute of Radiological and Medical Sciences (KIRAM) took part in a range of response measures around the clock.

      Both unmanned and regional radiation monitoring stations measured the radioactivity of air, precipitation, tap water and soil samples at shorter cycles. Weather information was analyzed, and measures were taken to monitor possible radioactive contamination at airports and sea ports. Food and tap water were also monitored for possible contamination. And, the several KINS experts were dispatched to Japan to protect Koreans living in Japan and assist Japanese rescue team by providing them with radiation safety education and monitoring for radioactive contamination.
  • Lessons-learned Activities
    • KINS has taken significant action to enhance the safety of reactors in Korea based on the lessons learned from this accident. A special safety inspection was conducted from March 21 to May 5, 2011 to establish countermeasures against severe accidents triggered by natural disasters that exceed the design basis and check the safety of Kori Unit 1, an aging NPP. The inspection team consisted of 73 experts including 37 KINS staffs and 36 experts from industry, university, and research institute. The safety was examined under a worst-case scenario with progression of an earthquake, large tsunami, power loss, and a severe accident in the areas below :
  • ※ 6 Inspection Areas
    • (Area 1) Safety of the structures and components against earthquakes and tsunamis
    • (Area 2) Safety of electric power, cooling and fire protection systems in case of inundation
    • (Area 3) Responses to severe accidents
    • (Area 4) Emergency response system
    • (Area 5) Aging NPPs and new NPPs
    • (Area 6) Research reactors, nuclear fuel cycle facilities and the Radiation Emergency Medical Center
  • ※ Key Results
    • Based on the results of the special safety inspection, the 50 improvement measures were derived:
  • Mid- and long-term Action Plan
  • As a strategy for enhancing the safety of NPPs, three-tiered activities have been implemented to assure the safety of NPPs against natural disasters and accidents that exceed the design basis.
  • Tier 1 Activities
    • Derivation of near/long-term means of improvement (by Regulatory body)
    • Preparation of comprehensive implementation plan (by Licensee)
  • Tier 2 Activities
    • Detail implementation plan for each means and establishment of standards
    • Evaluation of safety enhancement through analysis of weaknesses
  • Tier 3 Activities
    • Comprehensive re-establishment of the regulatory framework
    • Reflection of domestic/international actions to improve safety
  • The 50 safety improvement projects have been identified and implemented for all domestic NPPs with the aim of completion by 2015.
  • As shown in the following table, 21 of the 50 improvement projects were completed, and 29 are being reviewed.
