Radioactive waste 
Opinion of the Scientific Board on the deep disposal expert appraisal
The IRSN Scientific Board published on the 9th of November 2006 its opinion on the Institute's expert appraisal capabilities and resources concerning the deep, geological disposal of radioactive waste. It considers that the Institute is perfectly ready to carry out appraisal work in this field.

Launch of the European FUTURAE radioecology project under the leadership of the IRSN
The European FUTURAE project (‘A Future for Radioecology in Europe’), a component of European Commission EURATOM FP6 , began work on its two-year program on October 1, 2006. The purpose of the project is to carry out a feasibility study into the establishment of a network of excellence of radioecology as part of FP7. Under the leadership of the IRSN, FUTURAE brings together nine European partners representing research centers active in the field of radioecology together with radiological protection authorities. The first meeting of the consortium is held on October 10 and 11 at the IRSN Le Vésinet site (78).

Four IRSN research projects labelled


Four IRSN environmental research projects were labelled during summer 2006 by the French Territories Risk and Vulnerability Management Cluster. PRIME, PRISMES and MULTISTRESS, coordinated by IRSN, and CLARA II, coordinated by the école des Mines d’Alès - a leading French engineering institution- and to which IRSN participates.

New phase for MOZART
The LEA is going to begin a new test phase of the MOZART programme in the second half of 2006, whose aim is to provide additional data on the oxidation of zirconium alloys in an atmosphere containing air. These alloys are used for nuclear fuel rods cladding, and their oxidation during a nuclear reactor severe accident or an accident involving the draining of a spent fuel storage pool may have a fundamental influence on how this accident evolves. Following a variety of test campaigns on oxidation in pure air, with the zircaloy-4 and M5TM alloys, this new test phase will use as oxidising gases mixes of air + steam and oxygen + nitrogen with a variable proportion of oxygen.

ICRP Publication 85 in French
IRSN is publishing the French translation of International Commission on Radiological Protection (ICRP) publication 85: Avoidance of Radiation Injuries from Medical Interventional procedures
An history of sediments in the Rhone River
A new sediment sampling campaign was recently undertaken along the banks of the Rhone, downstream, with a view to reconstructing the history of how these massive sediment depositions formed. The ultimate goal of this is to assess the consequences of highly intense flood events on the deposition of radionuclides or other contaminants on the river banks. This study is part of Project EXTREME, the aim of which is to analyse the effect of extreme climate events on the deposition of radionuclides in various biosphere compartments.
Second prize for the best poster at the "Plutonium Futures - The Science 2006" conference
Béatrice Boulet, who completed her thesis in IRSN's Radiation Protection and Human Health Sector, was awarded second prize for the best poster at the "Plutonium Futures - The Science 2006" conference, held between 9 and 13 July 2006 in the United States. The prize was for her poster entitled "Selective extraction of Pu by calix[6]arene bearing hydroxamic groups. Application to bioassays".
