Energizer: Nuclear Energy Safety

Development and Installation of HEP and ECP Corrosion Monitoring Systems for Pt. Lepreau NGS

As part of our Atlantic Innovation Fund partnership with the Center for Nuclear Energy Research (CNER), we developed, tested, and manufactured two corrosion monitoring systems for use in CANDU nuclear power stations. The Hydrogen Effusion Probe (HEP) provides an on-line measurement of the rate of wall thinning in carbon steel pipes. It works by measuring the quantity of hydrogen which effuses through the pipe wall. The Electrochemical Potential Probe (ECP) provides an indication of the state of the oxide layer coating, the inside of the pipe and its susceptibility to the initiation of cracking. RPC staff worked with CNER to design and build the probes, prepared all the documents for installation on-site, built practice mock-ups, tested all the hardware, and wrote and tested all the software and electronics.

This project is an excellent example of collaborative research and development. The client has been cooperative and impressed with the rapid and timely developments.

The installation of both systems will take place in May 2006 at Pt. Lepreau NGS. A successful installation will lead to further market opportunities and position the CNER/RPC team for future nuclear research opportunities.
