【考案の詳細な説明】
この考案は内部発熱が生じる放射性物質粉末を
安全に収容する粉末容器に関するものである。[Detailed description of the invention] This invention relates to a powder container that safely accommodates radioactive substance powder that generates internal heat.
一般に放射性物質粉末は容器内において、崩壊
熱が必然的に発生するものであり、この発熱によ
つて粉末温度が上昇して容器内気体の膨張あるい
は粉末の含有水分の蒸発等によつて容器の内圧が
上昇するために高圧に耐え得る構造を必要として
いた。殊に放射性物質粉末を充填した容器の破壊
による汚染拡大は、安全性の点から重大な問題を
ひき起すおそれがあつた。 In general, radioactive material powder inevitably generates decay heat inside the container, and this heat generation causes the powder temperature to rise and the container to expand due to the expansion of the gas in the container or the evaporation of the moisture contained in the powder. As internal pressure rose, a structure that could withstand high pressure was required. In particular, the spread of contamination due to the destruction of containers filled with radioactive material powder could pose a serious problem from a safety standpoint.
この考案は上述した問題点を改善するためにな
されたものであり、崩壊熱が発生する放射性物質
粉末の最高温度を低く抑えるために伝熱効果を高
めるように形成した粉末容器を提供するものであ
る。 This invention was made in order to improve the above-mentioned problems, and provides a powder container formed to enhance the heat transfer effect in order to suppress the maximum temperature of radioactive material powder, where decay heat is generated, to a low level. be.
以下この考案による一実施例を添付した図面に
もとづいて具体的に説明する。図はこの考案によ

る。 Hereinafter, one embodiment of this invention will be described in detail based on the attached drawings. The figure shows a powder container 1 according to this invention, and the main body 2 is made of a metal with good thermal conductivity, such as aluminum. The inside of the main body 2 has an inner peripheral wall 2a as shown in FIG.
Fins 2b are integrally formed radially from the center toward the center. The radial fins 2b are equally spaced around the periphery at predetermined intervals.
また上記粉末容器１の開口部には蓋体３が装着
されるものであり、この蓋体３は本体２内の内容

のであり、容器内の粉末温度を低くおさえること
ができる。 As explained in detail above, the powder container according to this invention is made of a material with good thermal conductivity in consideration of the heat transfer effect, and has radial fins integrally formed from the inner circumferential wall of the container to the center. , the decay heat inevitably generated from the powder filled in the container can be quickly transferred to the outer periphery of the container, and the temperature of the powder inside the container can be kept low.
なお、上記粉末容器は冷却保存することにより
内部の最高温度を低く抑えることができるもので
あり、放射性物質粉末の崩壊熱が必然的に発生す
る粉末の貯蔵に効果的である。 Note that the powder container described above can keep the maximum internal temperature low by storing it in a cooled state, which is effective for storing powder in which decay heat of radioactive substance powder is inevitably generated.
