Domestic Cooperation

ATLAS DSP (Domestic Standard Problem)

  • Four DSP exercises have been successfully completed;
  • Around 17 organizations, including research institutes, a regulatory authority, nuclear industry, and universities have joined DSP exercises.
  • ATLAS DSP exercises contribute to;
  • Effective utilization of the ATLAS integral effect test data for resolution of safety issues
  • Validation of the safety analysis codes which include MARS-KS, SPACE, RELAP5, and TRACE
  • Establishment of a strong human network and sharing of technical expertise in the field of nuclear safety analysis

CUPIDERS Workshop (CUPID Users Group)

  • The CUPID Users Group (CUPIDERS) workshop is held to disseminate the knowledge on the component-scale thermal-hydraulic analysis based on the CUPID code on an annual base;
  • The annual workshop was held on Aug. 2013 at KAIST, Daejeon, Korea, on Aug. 2014 at Pusan National Univ., Busan, Korea, on Aug. 2015 at Seoul National Univ., Seoul, Korea, on Aug. 2016 at DCC, Daejeon, Korea and on Aug. 2017 at Hanyang Univ., Seoul, Korea.
  • Up to now, 14 domestic organizations, including KAIST, SNU, POSTECH, KINS, KHNP are participating to the CUPIDERS group, with official agreements with KAERI, and the CUPID code has been transferred together with relevant technology to several domestic industries including KEPCO-NF, KEPCO-ENC, FNC, SenTech, and KONES.

Short Course on the Severe Accident (Severe Accident Research Committee)

  • A short course on the severe accident was held on July 4 to 6, 2017 to discipline researchers, engineers, and students for phenomenological understanding and evaluation techniques on the severe accidents. The three days course dealt with overall topics on the severe accidents such as overview of the severe accident; core heat-up, melting, and relocation; lower head T/H and vessel failure; in-vessel retention by ERVC; fuel-coolant interactions; MCCI and debris coolability; hydrogen risks and control; fission product source term; severe accident management. More than 50 participants registered the course.
  • A workshop on the severe accident research was also held on July 6 to 7, 2017 to exchange and discuss the research activities on the severe accidents in KAERI, KINS, KHNP-CRI, KEPCO E&C, and academy. The workshop dealt with source term researches under severe accidents as a special topic. More than 80 participants attended the workshop.
