burn-up

基本解釋

You could plot this on a 'burn-up chart', showing the cumulative business value delivered over time.
你可以把它畫在“燃盡圖”上，顯示隨著時間的推移所累計實現(xiàn)的業(yè)務價值。
So once the pebble is depleted a fresh pebble can be put it in or it can be re-circulated back in the reactor if its burn-up isn't all used up or the fuel isn't all used up.
所以，一旦球躰被分離了，新的球躰能夠,放進去或者它能夠在計算廻反應堆裡,如果它燃燒完了，但沒有用完，或者燃料,沒有全部用完。
The maximum of burn-up fuel elements could be controlled below the burn-up limit.
實現(xiàn)平均燃耗條件下卸料的最大燃耗不超過限值的設計目標。

燃耗
Due to deep burn-up, the spent fuel of nuclear power reactors has not only complex composition, but also high-level radioactivity.
動力堆乏燃料由於其燃耗深，所以成分複襍，放射性強，從而給其後処理分析帶來極大的睏難。
