脉冲堆 meaning in English
pulsed reactor
Examples
- Expected value of finite fission chain lengths of pulse reactors
脉冲堆有限裂变链长的数学期望值分析 - Correction calculation for the duct of nuclear power institute of china ( npic ) pulsed reactor shows the results are more close to the measured ones
校算了中国核动力院脉冲堆的切向孔道，其中耦合抽样方法的计算结果更接近于实验测量值。 - The y rays detecting system for physical diagnosis in nuclear exploding must be calibrated in the pulse radiation field according to field spots . so the 12mv pulse x rays accelerator and the fast neutron reactor are selected as radiation sources for calibrating
核爆物理诊断探测系统需要在脉冲辐射场中按场点光子注量进行标定，为模拟核爆产生的辐射场，选定12mv脉冲x射线加速器和快中子脉冲堆为标定用脉冲辐射源。 - The let factors rlet ( rlet = 0 . 05 ) of neutron response for liftld in various n + y mixed fields in the fast neutron reactor have been determined experimentally due to the existing let effects of the response for liftld to neutron absorbed dose . the experimental results show that the let factor for neutrons from thermal energy to 5mev energy is about 0 . 050 . so it is workable to measure the photon fluence in the pulse reactor with 7liftld
为确定liftld能否用于n 、混合场的区分测量，本文定义了let效应因子，并对liftld的let效应因子进行了实验测定，测量结果表明： liftld对热中子至5mev中子响应的let效应因子值约为0 . 050 ，因此，选用~ 7liftld用于脉冲堆光子注量测量是可行的。 - A uniform state ion chamber with double layers has been developed for distinct measurement in various n + y mixed fields in the fast neutron reactor . the cavity material is 6lif + 7lif . the inner wall material is 6lif and the outer wall material is 7lif
根据let效应因子的测量结果和快中子堆y谱、中子谱等基本资料，以及~ 6lif和~ 7lif对中子响应灵敏度有较大差异这一特点，研制了以~ 6lif + ~ 7lif为空腔、 ~ 6lif为外壁、 ~ 7lif为内壁的具有双层室壁结构的均匀固体电离室，并将其用于快中子脉冲堆n 、混合场区分测量，彻底剔除了热中子的干扰。
