Abstract

Monitoring of 16N produced in the core is expected to provide an effective means to monitor the performance of components such as steam generators and reactor coolant pumps, which are located within the reactor pressure vessel in the IRIS reactor. The concentration of 16N at key locations within the reactor pressure vessel will depend on the flow path and rate, and can be used to monitor long-term system performance through trending and to monitor short-term transient events. Calculations show favorable 16N count rates for a gamma-ray detector located at a pressure-vessel port adjacent to a steam generator location. The gamma-ray dose to the detector electronics is within acceptable limits, and the background activity is not expected to interfere with the detection of 16N. Candidate gamma-ray detectors have been evaluated, and demonstration measurements have been carried out with a bismuth germanate (BGO) scintillator detector. Excellent separation between 16N gamma rays and background ( 60Co) gamma rays was observed.
