Leak Testing Project :
Nuclear Decommissioning Authority's Dounreay Site



NDA Dounreay Site

  • In the first quarter of 2009 H.T. Products' engineers travelled to the Dounreay Power Station near Thurso, Caithness, Scotland to conduct a leak testing operation in cooperation with the Nuclear Decommissioning Authority.


  • Sealed I.F. Container

    The focus of the operation was to establish the integrity of a proposed system built to seal containers of radioactive waste. The irradiated fuel, taken from the fast reactor core, had to be sealed into the 3 metre containers by a Remote Orbital Welding System (ROWS), drop-tested and leak tested under vacuum to measure the success of the weld and the container's durability.


  • In addition to the on-site leak testing and consultancy our engineers also provided:
    • A Mass Spectrometer Leak Detection system, designed and built by H.T. Products in Sussex.
    • A full training program for the staff who would be operating the leak detection system during the decommissioning.
    • Certification and supporting documents for the Leak Detection system, with traceability to National Standards.


    I.F. Container Under Test.

  • The leak test system itself incorporated a Pfeiffer HLT570 - Mass Spectrometer Leak detector and an Edwards XDS10 - Vacuum Schroll Pump with specially manufactured fittings and components for use with the I.F. containers. The system was built for use with Helium as the tracer gas but also implemented a specially designed Argon back fill system to eliminate the risk of contamination.




    The I.F. Container Leak Detection System


  • The Leak Detection System was also supplied with a calibrated reference leak and instructions for calibration to ensure the system performed accurately and effectively for it's required term of operation without the need for third party intervention.


  • H.T. Products is a supplier of leak detection equipment and is able to offer a system design and consultancy service for leak detection as well as a full range of vacuum components and fittings and a wide range of leak detection services including:


    • A range of calibrated reference leaks manufactured in house with our patented leak technology.


    • A calibration / recalibration service for leak equipment.


    • Professional advice or training in leak detection and leak technology.
