Online monitoring for fuel and control rods damage early detection


• Monitoring system for evaluation of integrity and early detection of damages of fuel and control rods.


• Allows real-time activity monitoring during Flux-Tilt and sequence changes, for quick and easy identification of the damaged fuel elements; also assures detection of second failures.


• Based upon continuous, real-time analysis of the OFF-GAS line for specific nuclides detection before and after the delay line: (133Xe, 135Xe, 137Xe, 138Xe, 85Krm, 87Kr, 88Kr, 89Kr, He).


• Easy installation on the OFF-GAS bypass, so that no modification of the plant major systems is required.


Already installed and functional at the Cofrentes Nuclear Power Plant (Spain)
