poison coefficientとは 意味・読み方・使い方

To provide a fuel assembly for boiling water type atomic reactors, in which the void coefficient becomes a proper value and the adjustment of reactivity can be realized in a proper flammable poison amount in a reactor core having high burnup and continuously operating for a long term.例文帳に追加

高燃焼度、長期連続運転の炉心において、ボイド係数が適切な値になりかつ反応度調整を適切な可燃性毒物量で実現できる沸騰水型原子炉用燃料集合体を得る。 - 特許庁

To provide a new burned material having a high Seebeck coefficient, a high electric conductivity, a sufficiently high thermoelectric conversion efficiency, a little poison and by which a thermoelectric conversion material can be obtained at a low cost because molding at low temperature and normal pressure burning can be performed and to provide the thermoelectric conversion material made from the same.例文帳に追加

高いゼーベック係数及び高い電気伝導度を有し、充分に高い熱電変換効率を有し、毒性が少なく、低い温度での常圧焼成によって成形を行うことができるために、低コストで熱電変換材料を得ることができる新規な焼成物及びそれからなる熱電変換材料を提供する。 - 特許庁

To prevent the increase of absolute value of void reactivity coefficient and reduction of neutron absorption effect of flammable poison and average axial power distribution by suppressing the increase of reactivity loss and the local power peaking of fuel rods adjacent to short size fuel rods and 4 corners position fuel rods for raising burnup.例文帳に追加

高燃焼度化を図る際、反応度損失や短尺燃料棒隣接燃料棒・４隅位置燃料棒の局所出力ピーキング増大を抑制しつつ、ボイド反応度係数の絶対値の増大や可燃性毒物の中性子吸収効果減少を防止し、軸方向出力分布を平均化する。 - 特許庁
