Show activity on this post. If you just sum the instantaneous currents of three phases, and they do not sum to zero due to imbalance, you get the instantaneous current running in the neutral wire. But that is also a sine wave, with some amplitude and some phase. So it is a vector su...

A method, using in-core detector readings, is developed for estimating three-dimensional power distributions within boiling water reactors. The power distributions are obtained by a kind of synthesis technique which consists of two types of calculations, i.e., horizontal, two-dimensional whole core,...
