Joint IAEA-GIF Technical Meeting/Workshop on Safety of Sodium-Cooled Fast Reactors

One of the key areas in both the Generation IV International Forum (GIF) and the IAEA programmes on innovative nuclear systems is the harmonization of safety approach, safety requirements and safety design criteria for the GEN-IV Sodium-cooled Fast Reactors (SDC_SFR). This topic has gained an increased importance in the aftermath of the accident that occurred in 2011 at the Fukushima Dai-ichi NPP.

In this framework, a series of joint IAEA-GIF Workshops on safety of Sodium-cooled Fast Reactors (SFR) has been held since 2010. The first joint IAEA-GIF SFR workshop, titled “Operational and Safety Aspects of Sodium-Cooled Fast Reactors” was held on 23-25 June 2010 at the IAEA headquarters. This was followed by a second Workshop titled “Safety Aspects of Sodium-cooled Fast Reactors”, held on 30 November-1 December 2011.

A third joint IAEA-GIF Workshop on “Safety Design Criteria for Sodium-Cooled Fast Reactors” was held on 26-27 February 2013. The Workshop focused on the development of the SDC_SFR, initiated by the GIF Policy Group (PG) in 2011. The GIF PG in July 2013 decided to invite the Regulators from GIF Member States and some International Organizations (IAEA, OECD-NEA, MDEP) to review the Phase 1 Report of the SDC_SFR, and to proceed with a Phase 2 work intended to quantify the design criteria as well as develop detailed guidelines to implement the general criteria. Meanwhile, the GIF and the IAEA have agreed to invite design organizations of innovative SFRs currently under development, with the aim to present engineering solutions able to meet the SDC_SFR.

In order to discuss these topics, and following the recommendations provided by the participants in the third IAEA-GIF Workshop, a fourth joint IAEA-GIF Workshop on “Safety of Sodium-Cooled Fast Reactors” is being organized by the IAEA. The main purpose of the Technical Meeting/Workshop is to present and discuss: i) the status of the SDC_SFR Phase 1 Report review by national Regulators and International Organizations; ii) the implementation of current SDC_SFR by the designers of innovative SFRs concepts; iii) the status of SFR_SDC Phase 2 development; and iv) specific safety design criteria e.g. practical elimination of accident situations, design extension conditions, sodium void reactivity effect.
