Review of radioactive gaseous and liquid effluent arisings in CAGR

The sources of the active nuclides present in gaseous and liquid effluents arising during the normal operation of CAGR power stations are identified. The methods of calculation used to predict the activity of nuclides present in effluents discharged during normal station operation are outlined. The results of calculations based on these methods are compared with operating station measurements to obtain an indication of their accuracy. Reasonable consistency between prediction and measurement is obtained in general, but where appropriate the comparison is used to make corrections to input data and the calculational route. (author)
