摘要： In forming a coolant flow hole at the bottom part fixing structure (2), big holes (13,13') are formed in the front surface and a number of small holes (14,14') are formed in the opposite surface. Two kinds of the holes are penetrated to communicate with each other so that limiters (Q,Q') are formed naturally in the center. The big impurity likely to give fatal damage to the fuel assembly can not pass through the limiters, but only the small impurity not damaging the assembly pass through. The sum of the small hole surface is almost the same as the sum of the big hole surface.

摘要： A method and a sintering furnace for sintering of uranium-zirconium mixed powder compacts in a low-vacuum environment are provided to produce a homogeneous sintered metal by preventing the evaporation of uranium and Zr(O) phase formed in the sintering process due to the inflow of air according to high vacuum. A sintering furnace for sintering of a uranium-zirconium powder compact comprises: a housing including a crucible housed in the housing to prepare a uranium-containing powder compact, and a heater hosed in the housing and disposed on an outer periphery of the crucible to supply heat to the crucible to sinter a uranium-zirconium powder compact; a vacuum system communicating with an opening at one side of a bottom part of the housing to control the degree of vacuum of the housing; and an inert chamber in which the housing is housed, and which has a gas inlet and a gas outlet formed at predetermined positions on upper and lower side faces thereof. The housing is maintained to a low-vacuum environment with a vacuum range of 1.0Î10^-4 to 1.0Î10^-1 torr by the vacuum system, and the crucible supplies a heat with a temperature range of 1300 to 1500 deg.C to sinter the powder compact.

摘要： 본 발명은 우라늄-지르코늄 분말 성형체의 저진공 소결 방법 및 소결로에 관한 것이다. 특히, 우라늄 및 지르코늄 분말을 혼합·성형한 후 저진공 분위기에서의 우라늄-지르코늄 혼합 분말 성형체의 소결 방법 및 소결로에 대한 것이다.
본 발명에 따르면, 우라늄-지르코늄 분말 성형체를 소결하는 과정에서, 고진공 상태인 소결로 챔버 내부에 불활성 기체인 아르곤 가스를 직접 장입하거나 고진공 소결로 외부에 아르곤 가스 분위기를 유지할 수 있는 챔버를 부착하여 소결로 내부로의 공기 유입을 방지하고 진공도를 제어함으로써 우라늄-지르코늄 소결체 합금에서 Zr(O) 상 형성과 우라늄의 증발 현상을 동시에 억제하여 균질한 우라늄-지르코늄 소결체 합금을 제조하는 유용한 효과를 제공할 수 있다.
