First SACSESS International Workshop
Warsaw, Poland
April 22‐24, 2015
Towards safe and optimized separation processes, a challenge for nuclear scientists
In the continuation of the ACSEPT international workshop series *
Draft Program
deadline for registration: 20 March 2015
http://www.sacsess.eu/home‐international‐workshop.php
Venue
Primate's Palace (Palac Prymasowski) ul. Senatorska 13/15 00‐075 Warsaw, Poland
* The first ACSEPT international workshop gathered more than 120 people in Lisbon in March 2010
The second one was organized as a specific session of the ATALANTE 2012 Conference in Montpellier
Thanks to the “International Workshop”, SACSESS gives not only the floor to its “Young Generation” but also allows you to meet internationally renowned researchers.
SACSESS is an EU collaborative project under the FP7 EURATOM framework and gathers 26 Partners. It aims at optimizing chemical separation processes previously selected within the FP7 ACSEPT project by focusing on all the safety issues related to the industrial implementation of a chemical process involving actinides. In SACSESS, Education and Training is a key issue for preparing the next generation of actinide scientists. www.sacsess.eu
