Meetings/Workshops on Nuclear Energy in France

Institute of Radioprotection and Nuclear Safety (IRSN)

Currently, new reactor designs (AP1000 and HPR1000 in particular) involving an IVR strategy were built in different countries and some of them are already in operation. Therefore it is important to share, as much as possible, scientific knowledge and methodology about IVR in order to help safety authorities making decisions. For this, a consensus on several issues should be reached between R&D experts.

The first objective of this seminar is to present the main outcomes of the European project IVMR (2015-2019) and to draw conclusions from that project. Among the main issues, the impact of transient evolutions of oxide and metal layers on the focusing effect and the issue of the long term mechanical behaviour of the ablated vessel wall will be discussed in details. Issues about external cooling efficiency, innovations and back fitting will also be addressed.

A second objective is to bring together an international panel of actors involved in severe accident management issues, either from the regulatory side or from research or industry, in order to share knowledge and views about the IVR strategy. Through panel discussions and technical sessions, all the important issues of the IVR strategy will be covered and discussed. The technical sessions will also include presentations from experts out of the IVMR project, in order to give the widest overview as possible on the IVR topic.

The IVMR seminar will be followed by a forum, open to all participants interested in continuing R&D about IVR. The purpose of the forum is to provide inputs for the R&D orientation of new research projects and to discuss about possible frameworks to continue collaborative R&D actions about IVR. This forum will focus on defining priorities for R&D on IVR and listing all the relevant experimental facilities or possible new facilities that could provide new and useful data for the improvement of the evaluation of IVR.

ATH2020 topical meeting is the fifth in a growing series organized by the ANS Thermal Hydraulics Division consisting of peer-reviewed, full-length technical papers covering recent advances in thermal hydraulics for nuclear applications. After San Diego (CA), Reno (NV) and New Orleans (LA) the last edition in Orlando (FL) in 2018 received more than 140 full-length papers. It is the first time this meeting is organized outside ANS summer or winter meetings.

Energy perspectives for the current century are dominated by the anticipated significant increase of energy needs due to the population growth and the likely economic development of emerging countries. Particularly, electricity consumption is anticipated to increase by a factor higher than two before 2050. Furthermore, the global climate change has now been proven to be partially related to the release of greenhouse gases from anthropogenic activities, including energy production. Considering that about 80% of our current primary energy comes from fossil energies, we have to face in the near-future a challenging issue: meeting the increasing energy needs while curbing the GHG emissions.

From this perspective, nuclear energy is considered as a potential contributor to the future energy portfolio to meet the energetic needs while preserving the climate but it also has to demonstrate that it can contribute safely and on a sustainable way. Its acceptance is closely associated to our capability to reduce the lifetime of the nuclear waste, to manage them safely and to propose options for a better use of the natural resources. Therefore, for its sixth edition and in the continuation of the series, the organisers propose to focus the ATALANTE Conference on the nuclear chemistry issues for all the fuel cycles and waste management options by giving the floor the international nuclear chemistry community.
