  • Th-232를 Fertile로 사용한 핵연료는 U-238을 Fertile로 사용한 핵연료보다 핵확산 저항성, 방사성 폐기물 생성면에서 유리하다. 본 연구에서는 MHTGR의 핵연료에 사용된 탄소피막 입자 기술을 토륨 핵연료에 적용하여 새로운 가압경수로용 핵연료로 개념 설계하였다. 핵연료의 설계안을 울진 3,4호기 집합체 설계안에 적용하여 해적 타당성을 살펴보았다.

  • An optimization of KTF thorium fuel assembly design was performed on the basis of the design parameter studies. Optimization goals ware to make the core have both proliferation resistance and fuel cycle economics. Four kinds of proliferation resistance indexes were used; SNS, TG, BCM, Toxicity. A new index, FEI was regarded as a limiting index for the maximization of fuel cycle economics. Optimized thorium fuel design was applied for APR-1400 reactor core. Nuclear core design procedures were examined to solve the thorium fuel reactor problems. It was shown that heterogeneous thorium fuel core option is acceptable in safety and economics aspects.

  • 건식공정 (pyrochemical process 혹은 pyroprocessing)은장수명핵종의 소멸처리를 위해서는 장수명핵종을 분리한 뒤 연료로 제조하여야 하며, 분리 공정은 습식공정과 건식공정으로 크게 나누어진다. 용융염을 사용하는 습식공정에 비해 2차 방사성폐기물의 발생량이 적고 공정이 간단하고, 핵확산에 대한 저항성이 매우 크다는 장점 때문에 미래의 핵주기 기술로서 주목받고 있다. 소멸처리를 위해서는 사용 후 핵연료 내에 존재하는 장수명 핵종군 원소들을 분리하고 소멸처리용 연료에 적합한 형태의 물리 화학적 형태로 전환시켜야 한다.(중략)

  • Various type of tritium wastes can be produced from nuclear fuel cycle process satisfying non-proliferation, CANDU reactors, and nuclear industry. Activities of tritium processing in the world were surveyed to develope the processing technologies of tritium wastes. The tritium wastes were classified into gas phase, liquid phase, and organic phase. And the treatment techniques for the tritium wastes are analyzed. Development of tritium processing technologies is essential to finding public acceptance of radioactive wastes and forming a solid foundation to foster the growth of nuclear industry in Korea.

  • The leading countries in nuclear technology development are concentrating their efforts on the development of Sodium-cooled Fast Reactor, which is one of the Generation-IV nuclear reactor systems characterized by a sustainability, an enhanced safety, proliferation resistance, and improved economics. Especially, the Republic of Korea is developing a Sodium-cooled Fast Reactor equipped with metallic-fuel. This type of fast reactor has superior inherent safety and passive safety characteristics. Further, sodium-cooled fast reactors enable the reuse of spent fuel and the closing of fuel cycle, thus, it increases the sustainability of nuclear energy. Many countries are planning the deployment of sodium-cooled fast reactors before 2050 in their energy mix.
