Description

Recently, according to the improvement of fuel performances, short-lives nuclides such as 19O and 16N have become mainly of the gaseous radioactivity in the turbine system at BWR plants. Therefore, the variation of the flow rate in main steam system greatly influences to the area radiation level, and it is very important to grasp the flow rate and the relations to the dose rate. On the other hand, the conventional flow rate measuring devices are accompanied with their inherent instabilities of indication on measuring the steam flow. In this study, we confirmed the existence of these short-lives nuclides and their contribution to area dose rate by in-situ measurement using a portable Ge(Int) spectrometer, and developed a method for estimating flow rate by radioactive gases analysis
