IRSN announces collaboration with 6 new European projects
The IRSN is participating in 6 of the new European projects selected in June following the 2012 call for tenders for Euratom's 7th Framework Programme, which is focusing on research into
nuclear safety. The institute is coordinating one of these projects, Passam (Passive and Active Systems on Severe Accident source term Mitigation) the aim of which is to investigate the possibilities of systems developed inside nuclear reactors for limiting emissions in the event of a core melt accident, especially passive systems. The IRSN is also the protagonist of Project Cesam (Code for European Severe Accident Management). This project is designed to improve the AstecGLO software package, the European benchmark for calculating severe nuclear reactor accidents, so that it can also be used for accident management analysis. The institute is also participating to a varying extent in four other projects: Nuresafe (Nuclear Reactor Safety Simulation Platform), Alliance (Allegro - Implementing Advanced Nuclear Fuel Cycle in Central Europe), Sacsess (Safety of Actinide Separation processes) steered by the CEA, and Prepare (Innovative integrative tools and platforms to be prepared for radiological emergencies and post-accident response in Europe) coordinated by the Karlsruher Institut für Technologie.

Results of IRSN’s 2012 thesis seminar
IRSN’s annual “Journées des Thèses” (Thesis Seminar) was held this year from the 2nd to
the 5th October 2012 in Le Croisic (South Brittany).
This residential seminar, a privileged moment for meetings and exchanges within the world of IRSN research, is the occasion for PhD students and post-doctoral fellows of the Institute to present their results to colleagues and scientists from different research organisations.
The first day, dedicated to presentations by academics and young researchers, shed light on the various research work being carried out within different collaborations.
Over the following days, the presentations of research directors, PhD students and post-docs of the different units enabled a comprehensive overview of research within the Institute to be drawn up. The seminar was also the occasion for PhD students and researchers to become familiar with the challenges and expectations with respect to the basic foundations of higher education and research and to prepare a contribution. In total, nearly 80 presentations were given at the seminar, which was attended by some 200 persons.

The IRSN signs a research convention with the IRSTV
On August 9, the IRSN signed a research convention with the Institute of Research into Urban Sciences and Techniques (IRSTV) for a period of 4 years, following on from a partnership led since 2010 on two projects initiated by the French Research Agency
(Vegdud and Inogev).
The IRSTV is a multi-disciplinary research federation which acts as a federating force in the field of urban sciences and techniques. Its main mission is to develop the knowledge and tools which contribute to sustainable urban development but also to lead federative research projects in this field in response to regional, national and European invitations to tender.
The IRSN will participate in the overall coherence of projects in the atmospheric domain and on issues linked to the transfers of gases and aerosols, particularly exchanges between interfaces (air-surface of a building, air-vegetation, air-soil). In the framework of the convention, the IRSN’s Laboratory of Radioecology of Cherbourg-Octeville (LRC) will firstly study the dispersion and deposit of radionuclides in the urban environment.
Very little research has been led in this field, either by experiments and modelling, due to the heterogeneity of the urban environment (different surface properties, variable meteorological conditions), which is hard to take into account in operational models to assess the dosimetric impact on humans when radionuclides are released into the environment following an accident or during the normal functioning of nuclear facilities. The IRSN’s partners in this research will be the École Centrale de Nantes, the French Institute of Science and Technology for Transport, Development and Networks (IFSTTAR), and the Scientific and Technical Centre for Building (CSTB).

The IRSN attributes the first Creativity Award
Sabine Charmasson, IRSN manager working at the LERCM (Laboratory of Radioecology Studies of Continental and Marine Environments) received the IRSN’s first Award for Creativity in Research.
The award was attributed during the first Exploratory Research Seminar, organized during one of the days devoted
to the 2012 thesis presentations, and recognizes her work studying the high levels of radioactivity of organisms living near hydrothermal sources at great depths in the ocean. This research has led to the publication of two articles, one in the 'Journal of Environmental Radioactivity' and the other in 'Science of the Total Environment'.
The exploratory research performed at the IRSN aims to encourage innovation and the creativity of the Institute’s researchers by offering them the chance to work on an original idea concerning subjects that are not dealt with in the research programs underway and which therefore fall outside of the usual sphere of programmed research. The IRSN has created this award to recognize the efforts of those who lead particularly innovative exploratory research projects presenting a high degree of risk.
Three to five ‘exploratory’ projects per year are selected by a permanent internal evaluation committee, named by the Scientific Director of IRSN. Each project receives a maximum budget of 150,000 Euros, attributed by the Scientific Director for 18 to 24 months of research, and is evaluated at the end of this period on the basis of a final report. Between 2007 and 2011, 15 projects have been selected from the 41 put forward.
For this first IRSN Award for Creativity, the Scientific Director of the IRSN chose five particularly worthy projects from those which had been completed. The initiators of these five pre-selected projects were asked to present them during the Seminar and the final choice of the winner was made by a panel of experts from the IRSN. Plans are afoot to create a new Award for Innovation within two or three years when sufficient projects have been completed.

IRSN conducting research with AECL on the effects of low doses of tritium
IRSN and AECL (Atomic Energy of Canada Limited) are conducting an experimental research programme on the possible health effects of chronic exposure to low doses of tritium. Both
organisations want to find solutions for problems caused to society by the emission of this radionuclide by new generation power stations.
The four-year collaboration agreement was signed in June 2011 and aims to acquire new scientific knowledge on this radioelement that is present around nuclear power stations or installations such as ITER. The first contamination experiments aiming to study the effects of tritium were successfully carried out in Canada in March and July of this year. IRSN is contributing its scientific knowledge in nuclear toxicology analysis (biochemistry, histology, gene expression) on different types of biological tissues (LRTOX - Experimental Radio-Toxological Laboratory) as well as its capacity to study DNA damage (chromosome anomalies, breakage) (LDB - Biological Dosimetric Laboratory). As for AECL, it has the infrastructure required to study the effect of tritium contamination on mice over several months and to examine the biokinetics and bioaccumulation of tritium in cases of chronic contamination. The programme should be finished by the end of 2014.
