用质谱法测定反应堆元件的燃耗

Burn-up Determination of Nuclear Fuel by Mass Spectrometry

本文介绍了用质谱法测定反应堆元件燃耗的方法。铀同位素比值法测定燃耗的误差为(3.0—5.0)%,燃耗监测核素(Nd、Mo)和剩余铀含量测定法测定燃耗值的总误差为(1.6—2.0)%。

The mass spectrometric determination of burn-up of nuclear fuel is presented. The measured accuracies determinated respectively on uranium isotopic ratio and indicators are (3.0—5.0) % and (1.6—2.0) %.
