摘要： The present disclosure relates to a pellet containing an oxide additive to improve a nuclear-fission-gas-adsorption ability of a uranium-dioxide pellet used as nuclear fuel and increase the grain size thereof, and to a method of manufacturing the same. A La2O3—Al2O3—SiO2 sintering additive is added to uranium dioxide so that mass movement is accelerated due to the liquid phase generated during sintering of the uranium-dioxide pellet, which promotes the growth of grains thereof. Further, since less volatilization occurs during sintering due to the low vapor pressure of the liquid phase, efficient additive performance is exhibited, so the liquid phase surrounding the grain boundary effectively adsorbs cesium, which is a nuclear fission gas.

摘要： A heat exchanger that can mechanically automatically control a level of cooling water according to heat generation of the fuel cell. The heat exchanger includes a housing having a cooling water inlet and an outlet connected to a fuel cell stack, a moving plate which moves reciprocally in the housing and discharges cooling water filled in the housing to the stack when it moves in a one direction and when it receives a steam pressure from the stack it moves in an opposite direction, and an elastic member that applies a force to the moving plate in the one direction. The heat exchanger can automatically maintain the level of cooling water despite a difference in heat generated between a full and a partial load operation of the fuel cell obviating complicated electronics such as a thermo-sensor, a valve, or a controller. Also, under a partial load, the exposure of flow channels to superheated steam is avoided, thereby extending the lifetime of the fuel cell.
