Abstract: 

Interaction of fast neutrons with oxygen atoms of cooling water in reactor core leads to the production of 16N isotope which emits 6.13 MeV gamma ray. A system is developed to measure the16N gamma ray activity using a ф5.08cm x5.08cm NaI(TI) detector. A suitable electronic system is used to count 16N gamma rays in different reactor powers in order to calibrate the 16N system in terms of reactor power. Some non-linearity in the system behavior have been observed and discussions have been presented for this effect.
