大粒子と小粒子を用いたスフェアパック充填技術に関して、4種類の模擬粒子を用いた充填試験を実施した。小粒子の浸透特性は材質と比重に依存しないため、燃料ピンの内面腐食を防止する酸素ゲッターとして働く金属ウラン粒子を、スフェアパック燃料に添加する可能性が提案された。

A vibrational sphere-pack technology employing large and small particles is discussed in the manner of simulation to the fabrication of atomic fuel pin, by four kinds of model particles.The infiltration property is almost free from the sort of materials and the weifht density.From this result,the feasibility to mix the heavy metallic uranium as the getter for absorbing oxygen, thereby prevents the oxidization of fuel pin is suggested.
