burn-up

基本解释

You could plot this on a 'burn-up chart', showing the cumulative business value delivered over time.
你可以把它画在“燃尽图”上，显示随着时间的推移所累计实现的业务价值。
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，一旦球体被分离了，新的球体能够,放进去或者它能够在计算回反应堆里,如果它燃烧完了，但没有用完，或者燃料,没有全部用完。
The maximum of burn-up fuel elements could be controlled below the burn-up limit.
实现平均燃耗条件下卸料的最大燃耗不超过限值的设计目标。

燃耗
Due to deep burn-up, the spent fuel of nuclear power reactors has not only complex composition, but also high-level radioactivity.
动力堆乏燃料由于其燃耗深，所以成分复杂，放射性强，从而给其后处理分析带来极大的困难。
