Introduction words

Dear colleagues

The 50èmes Journées des Actinides and 13th School on the Physics and Chemistry of the Actinides were planned to take place in March 2020 in Brittany.

Unfortunately, a microscopic (125 nm diameter) virus emerged and spread around the world at the speed of light. One year later, human kind is still fighting against it and some hope slowly appears with new vaccines and promising medicines.

In this context, we first thought to postpone these scientific events to November 2020, then to March 2021 in Brittany. The situation still being critical all over the world, we had to make a decision to organize them FULLY ON-LINE. We know that the spirit of JdA and SPCA, based on long and lively discussions,  will be partly lost behind our webcams. But we hope our exchanges will be fruitful and will motivate all of us to participate to the next editions.

Our greatest hope is that all of you will stay away from Sars-Cov-2 disease and that we can meet again soon at JdA2022 or other conferences.

We will do our best to organize the most enjoyable on-line meeting.

50èmes Journées des Actinides

50èmes JdA-2021, 22 - 25 March 2021, Fully virtual on-line conference!!!

The 50èmes Journées des Actinides (JdA-2021) will be held on-line from 22 to 25 March 2021, organized by the “Institut des Sciences Chimiques de Rennes” (ISCR,

The Journées des Actinides is an international conference series providing an informal annual forum for the discussion of current research on the physical and chemical properties of actinide elements, their alloys and compounds. Following the editions held in Erice (Italy, 2019), Praia de Porto Novo (Portugal, 2018), Karpacz (Poland, 2017), and Alpe d’Huez (France, 2016), JdA-2021 will cover the following topics:

  • inorganic and organometallic chemistry
  • materials and nanomaterials
  • strongly correlated systems, superconductivity, and quantum criticality
  • theory and band structure
  • actinide production and handling
  • safety of the nuclear fuel cycle
  • nuclear safeguards and security
  • radiation protection
  • environment contamination, remediation, and decommissioning

JdA-2021 encourages open discussions on different topics, from fundamental to applied research, in a mixture of oral presentations and poster sessions. Scientists, engineers, and students from universities, national laboratories, and the nuclear industry are invited to participate and make technical contributions.

Following the philosophy of this conference, recent and/or unpublished results will be presented. Oral presentations by PhD students and young researchers will be favoured.

Oral sessions will be concentrated in the morning (8h30 - 13h00 local time, UTC +1).


The 13th School on the Physics and Chemistry of the Actinides

13th SPCA, 22-25 March 2021, On-line Lectures

The 13th SPCA will be organized FULLY ON-LINE as a tutorial to the JdA-2021 conference. The school is a unique opportunity for students, young researchers and other engineers to gain knowledge from expert master-classes in various areas of different actinide science aspects.

We feel confident that you will enjoy these very special 13th SPCA and 50èmes JdA-2021 events and that the modern videoconference tools will enable fruitful discussions.

On behalf of the Local Organising Committee
