absolute reactivityとは 意味・読み方・使い方

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

In the case of 100% heavy water, the absolute value of void reactivity in an initial state of combustion is as small as about 0.55 $, but the void reactivity is transferred to positive side by the accumulation of ^239Pu generated by neutron capture reaction of ^238U or nuclear fission product according to combustion.例文帳に追加

重水１００％の場合、燃焼初期におけるボイド反応度の絶対値は０．５5＄程度と小さいが、燃焼に伴い^２３８Uの中性子捕獲反応によって生成される^２３９Ｐuや核分裂生成物の蓄積によってボイド反応度は正側に移行する。 - 特許庁

To provide a dielectric ceramic composition having a high dielectric constant, a high quality coefficient, a temperature coefficient of a small absolute value, and non-reactivity with a low sintering temperature and an internal conductor material.例文帳に追加

高誘電率、高品質係数、絶対値の小さい温度係数、低焼結温度および内部導体材料との非反応性を有する電体磁器組成物の提供。 - 特許庁
