    The purpose of the meeting is to provide a forum for the presentation and discussion of the progress in methods and technologies used for the irradiation testing of nuclear fuel achieved since the last IAEA meeting in the area held in 2007. Emphasis will be placed on advanced techniques applied for the understanding of high burnup fuel behaviour of water cooled power reactors, but the meeting will also be open for discussion of testing techniques applied or to be developed specifically for new fuel and structural materials considered for Generation IV (GIF) systems. These reactors require development, qualification, testing and deployment of improved and innovative nuclear fuel and structural materials with very high radiation resistance, corrosion/erosion and other key operational properties. At present, a major effort in the area has been made on systems with sodium cooled fast reactors, and 2 more FR designs (lead and gas-cooled) were selected within GIF. That is why presentations on fast neutron fuel and structural materials testing are welcome.

    Presentations could include items such as innovative methods for testing fuel in non-rod configurations (e.g. discs, wafers, etc.), re-fabrication techniques for irradiated fuel, ramp testing facilities, as well as more traditional techniques for the measurement of temperature, fission gas release and dimensional changes. Experimental methods used to control local power of the fuel under test to match operational conditions such as transients or load follow operation could also be described as well as in-reactor loops for controlling water chemistry or other environmental conditions (e.g. liquid metal, supercritical water, molten salt). Theoretical and computational studies supporting the results expected from different techniques are welcome, as are results demonstrating successful implementation of particular techniques. The aim of the meeting, however, is to strengthen and widen the knowledge base on in-pile measurement techniques as applied to nuclear fuel rather than to exchange and present fuel properties and performance data.


    Papers are invited on all aspects of in-core testing of fuel materials.

    Particular topics include, but are not limited, to:

    Fuel rod instrumentation:

    • Fuel centre temperature

    • Irradiated fuel pellet drilling

    • Thermal-hydraulic conditions in loop systems (temperature, pressure and flow)
    • Coolant chemistry including injection / addition systems
    • Power monitoring and control including transients and load follow
    • Temperature monitoring and control
    • Gas flow monitoring and control

    • Clad thermal conductance including effects of oxide and crud
    • Clad creep
    • Clad irradiation growth
    • Clad corrosion rates (in situ monitoring)
    • Fuel thermal conductivity degradation
    • Fuel creep
    • Fuel densification and swelling
    • Fission gas release (e.g. with gas flow and spectrometry)
      Development of new instruments for in-pile testing of Generation IV fuel and structural materials: Instruments able to operate in liquid metals, supercritical ‘steam’, molten salt etc.
    • Linear Voltage Differential Detectors for high temperature (above 400oC)
    • Online cladding corrosion detectors (potential drop, EIS / ECN)
    • Electrochemical sensors (ECP, conductivity etc.)
    • In core Eddy-current techniques e.g. for detecting development of defects
    Theoretical and computational techniques:
    • Thermocouple de-calibration
    • Interpretation of instrumentation results
    • Finite element analysis for thermal / stress calculations
    • Modelling of instrumentation (e.g. LVDTs) for improved design and fabrication

      The meeting may be attended only upon official designation. Participants should complete the attached Form A (Participation form) and B (Form for submission of a paper) and send them, together with an abstract of approximately 300 words to the appropriate national authority (Ministry of Foreign Affairs or National Atomic Energy Authority) for subsequent transmission to the IAEA, not later than 11 June 2012, with copies to the Scientific Secretary Mr. Victor Inozemtsev, the Meeting Co-ordinator Mr. Wolfgang Wiesenack, and the Meeting Chairman, Mr. Rudi Van Nieuwenhove. The abstracts should summarize the content and principal conclusions of the paper. The format of the IAEA Technical Meetings presumes active contribution from all participants either in the form of papers/presentations, or e.g. chairing sessions and preparation of topical summaries.

      Prospective participants will be notified about the acceptance of their applications, and a preliminary programme will be published on the meeting web-site by 2 July 2012. As usually practised in this type of meetings, the programme will include a summary session to permit participants to discuss section summaries and to make recommendations to the IAEA on future work in this field.

      Upon arrival to the meeting venue the authors are requested to bring in electronic form (on a CD or a memory stick) their papers in MS Word format and their presentations in Power Point or PDF format.


      The meeting will be held at the: Kaserna, Fredriksten Festning (Fortress), Halden

      Accommodation for delegates and any accompanying persons will also be at Kaserna and delegates should arrange this through the meeting Administrative Officer, Ms Turid Danielsen. It is anticipated that accommodation costs will be around 525 NKr per day. Depending on demand, help and advice in arranging activities for accompanying persons will be provided.

      Overlooked by the mighty Fredriksten Fortress, Halden possesses great historical treasures and a variety of sights. As well as the beautiful manor house of Rød Herregård with its peaceful garden, the harbour and old town offers the opportunity for strolling in pleasant surroundings. For the more active, it is possible to enjoy a round of golf in the historical surroundings of the Fredriksten Fortress.

      Half a day of the meeting will be set aside for a technical visit to the facilities of the Halden Project.

      Further details of travel arrangements, technical visit and social events will be provided to participants at the meeting website. The link to this website will be made available in due course.

      Designated participants who require a visa to enter Norway should submit the necessary application form in due time to the nearest diplomatic or consular representative of Norway.


      In accordance with the established rules, Governments or other national authorities are expected to bear the travel and other costs of designated participants in the meeting. Limited funds are, however, available to help cover the cost of participants from Member States eligible to receive technical assistance under the IAEA’s technical cooperation programme. Such assistance can be offered, upon specific request, to one participant per country provided that, in the IAEA’s view, this participant will make an important contribution to the meeting. The application for financial support should be made at the time of designation of the participant.

      Please note that compensation is not payable by the IAEA for any damage to or loss of the expert’s personal property. However, for the period of the expert’s participation in the above IAEA meeting on the dates indicated, including travel between the expert’s residence and the duty station, the expert will be covered under the IAEA’s insurance policy for permanent total disablement or death resulting from service-incurred accidents or illness up to a maximum of €100 000, for permanent partial disablement resulting from service-incurred accidents or illness up to a maximum of €100 000 and for medical expenses up to a maximum of €20 000 plus €10 000 for supplementary travel and accommodation expenses in case of illness or injury resulting from service-incurred accidents or illness, in accordance with the terms of the IAEA’s relevant insurance policy.
