Abstract
In the operation of a nuclear reactor it is essential to continuously determine the rate of leakage of fission products from the reactor core into the primary coolant stream. Unfortunately, due to the mode of generation and release of fission products, the complex nature of their gross decay and their varied physical and chemical characteristics, standard monitoring equipment, techniques and analytical procedures are inadequate. In this article a unique method is described for continuously determining the fission product release rate from an open cycle gas cooled reactor as well as the methods of calibration analysis.
