    I. BACKGROUND

    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.

    II. TOPICS TO BE COVERED

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

      IV. DEADLINE FOR PAPERS AND PARTICIPATION IN THE MEETING

      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.

      V. VENUE AND ACCOMMODATION

      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.
