Management of Spent Fuel from Power Reactors


Technical Meeting on Spent Fuel From Fast Reactors

14 – 16 November 2011,
IAEA Headquaters, Vienna, Austria



I. INTRODUCTION

GIF and INPRO initiatives are looking into generation 4 nuclear energy facilities with the advanced fuel cycles that involve recycle of nuclear fuel and use of fast reactors in order to improve the sustainability of nuclear energy application. In many countries that are receivers of the nuclear technology, the long term storage (of 100 years or even more) is becoming reality. In this period the new generation of reactors and fuel cycles will be deployed.

While there is a pool of information on current storage of spent fuel from light water reactors, there is very little information internationally available on experiences with management of fast reactor spent fuels. There is a significant number of fast reactors (37) in the world that are either in operation or in shutdown and there is experience gained on their spent fuel management. Some of these reactors are experimental, some prototype and there are more than 10 commercial size fast reactors.

The primary objective of this technical meeting is to obtain, exchange and preserve data and information on the experiences on management of spent fuel from fast reactors. The presentations and papers obtained at the TM will be used, through subsequent consultancies, as a basis for a report on the topic of spent fuel management from fast reactors.

IV. PARTICIPATION IN THE MEETING

The primary objective of this technical meeting is to obtain, exchange and preserve data and information on the experiences on management of spent fuel from fast reactors. The presentations and papers obtained at the TM will be used, through subsequent consultancies, as a basis for a report on the topic of spent fuel management from fast reactors.

Each person wishing to participate in the meeting is requested to complete the Participation Form and the Form for submission of a paper (Form A and B attached).

The designation of a participant will be accepted only when transmitted through the Government of a Member States of the IAEA or by an organization invited to participate not later than 28 July, 2011.

V. PAPERS AND PRESENTATIONS

Participants will be asked to prepare a paper on the topic of cost of spent fuel management options. The presentations will have a duration of approximately 20 minutes and it is preferred that they are prepared in MS PowerPoint format. Papers will be published in the resulting technical document. Contributed papers should be submitted in English with an electronic version provided to the scientific secretaries prior to the meeting. The designated participants should provide an abstract of approximately 250 words for their paper as well as the completed Form for Submission of a Paper (Form B attached) to the scientific secretaries by 1 September, 2011. The abstract should be sent by e-mail to the scientific secretary at Z.Lovasic@iaea.org, using MS-WORD and Times New Roman as the text font. The full paper should be sent to the scientific secretaries by mail by 1 November 2011 and the presentations should also be sent to the scientific secretaries by mail by 1 November 2011.

VI. VENUE

The meeting will be held at the IAEA's Headquarters in the Vienna International Centre (VIC), Meeting Room A 2712 Wagramer Strasse 5, 1400 Vienna, Austria. Participants are advised to arrive one hour prior to the convening time of the meeting to allow for timely registration.
