  • The hold-down spring forces of Kori nuclear fuels were measured for seven fuel assemblies having 1 to 4 cycles of irradiation histories in the Kori Unit-1 and -2 reactor. The fuel assemblies examined had burnup from 17 to 38 GWD/MTU and the examination was conducted in KAERI PIEF spent fuel storage pool with the newly developed underwater hold-down suing force measuring device. The measurement was made within the elastic deformation ranges and the trends of hold-down spring force relaxation behavour were examined.

  • The code WIMS-AECL has been used for the lattice analysis of DUPIC fuel. The lattice parameters calculated by the code is sensitive to the choice of number of parameters, such as the number of tracking lines, number of condensed groups, mesh spacing in the moderator region, other parameters vital to the calculation of probabilities and burnup analysis. We have studied this sensitivity with respect to these parameters and recommend their proper values which are necessary for carrying out the lattice analysis of DUPIC fuel.

  • 소형원자로는 크기가 작아서 경제성이 떨어지는 단점이 있지만 안전성이 높아 수출용 원자로로서 가능성이 높다. 소형원자로의 이용 범위는 지역난방용 원자로, 담수화플랜트, 선박 및 잠수함의 추진용 원자로 그리고 우주 탐사용 원자로 등으로 확대되었으며 다양한 형태로 개발되었다. 소형원자로 개발에 있어서 주기길이 연장은 핵연료주기 경제성에 매우 큰 영향을 미친다.(중략)

  • Metal fuel, which was abandoned in the 1960's in favor of oxide fuel, has since then proven to be a viable fast reactor fuel. Key discoveries allowed high burnup capability and excellent steady-state as well as off-normal performance characteristics. Metal fuel is a key to achieving inherent passive safety characteristics and compact and economic fuel cycle closure based on electrorefining and injection-casting refabrication.
