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, ⁸⁵Kr^m, 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)
