ジャーナル フリーThe continuous release of fission-gas from ceramic fuel was measured during irradiation in the Hitachi Training Reactor. Two different types of in-core assemblies were devised. In these assemblies, UO2 specimens were heated up to 2, 000°C by a heater rod, or else cylinder of tungsten. These assemblies can usefully serve in the study of fission-gas release rate at tem-peratures conducive to grain growth.
In these assemblies, the fission-gases are purged by continuously flowing Ar or else He, and led out of the reactor, where the radioactivity was measured with γ-ray spectrometer. The radioactivity of Ar and fission-gas was left to decay in a radioactivity decay tank and a fission product collection train submerged in the reactor pool.抄録全体を表示PDF形式でダウンロード (466K) -

ジャーナル フリーIntense ebullition occurs at the liquid front heading a falling sheet of water over a heated vertical surface, as in the case of emergency cooling. It has been ascertained that the displace-ment velocity of this liquid front is nearly constant for the values of specified parameters such as wall temperature before cooling, flow rate of cooling liquid, and the physical properties of heated wall and cooling liquid. Observations were conducted on the liquid front velocity using a heated wall of stainless-steel and with tap water as cooling liquid. An analysis has been made on the basis of a two-dimensional transient heat conduction model, the result of which proves to be valid for explaining the liquid front behavior when account is taken of boiling heat transfer. The liquid front velocity is given by
where N denotes a reference state. The above relation is applicable in the region of flow rate from 0.245 kg/m • sec to 2.45 kg/m • sec.抄録全体を表示PDF形式でダウンロード (536K) -
