Conference Theme

The primary objective of the  » Tracer  » conferences remains to present the current status and trends on tracing methods and their applications. It is opportunity for attendees from different fields to exchange scientific information and knowledge about tracer methodology and applications in one field that may also be applied, with modifications, in another field.

The target participants are scientists, engineers and technologists in various areas of research and industry: chemistry and chemical engineering; metallurgy; environ mental aspects; air and water quality; pollutant transport in soils, aquifers, rivers and the atmosphere; bio-engineering and food engineering; pharmacy and medicine; petroleum industry etc.

Both fundamental aspects and industrial applications are planned to be covered. Advances in various fields will be high-lighted as shown below in development and applications section.

Development and applications


  • New tracers (including radiotracers, chemical tracers, isotopic ratios, nanoparticles etc.) 
  • Detection techniques and equipment (online, offline, scanning, camera, tomography, particle tracking, etc.) 
  • Reactive tracer experiments and interpretation 
  • Validation of computational fluid dynamics (CFD) simulations by tracer experiments 
  • Numerical residence time distribution (RTD) 
  • Data treatment and modeling
  • Macro and micro-mixing
  • Modeling and simulation of reactors, flows, etc.


  • Pure science experiments
  • Industrial process equipment
  • Oil field evaluations and production
  • Energy production
  • Tracer methods (new methods and applications)
  • Geology, hydrogeology, hydrology, and soils remediation
  • Environment
  • Food and biological engineering
  • Mineral and metallurgy processes
  • Pharmaceutical and medical examinations

Scientific and organizing committees

  • The committee of the international TRACER Series of conferences composed of the two chairs Julien Laurent and Olivier Potier, who succeeded to Jean-Pierre Leclerc in 2017, and a representative of IAEA Patrick Brisset. Jean-Pierre Leclerc was the initiator of the TRACERS Series of conferences at the Université de Lorraine (formally Institut National Polytechnic de Lorraine) in 1998.
  • An international scientific committee. This committee may be different from one conference to another. It is nominated by the committee of the international TRACER Series of conferences.
  • Local organizing committee of the host country defined by the committee of the international TRACER Series of conferences, and UL-PROPULS (Université de Lorraine), formally PROGEPI for the global international organization.

Previous events

The first conference on « Tracers and tracing methods » was arranged in Nancy, France, in November 1998 as a national French event. The main organizer was former Laboratoire des Sciences du Genie Chimique, (LSGC, UPR CNRS 6811) that became in 2010 Laboratoire Réaction et Génie des Procédés (LRGP, UPR 3349).

The second conference on the same subject was organized as an international event, also in Nancy and by the same main organizer as the first conference. It took place in May 2001.

The third conference briefly called « Tracer 3 », moved outside France to the small holyday resort city of Ciechocinek in Poland and was arranged in June 2004. The local organizer was Warsaw University of Technology.

The fourth conference with the nickname « Tracer 4 » moved back to France to the small village of Autrans and was arranged in October 2006. The local organizer was Commissariat à l’Energie Atomique, CEA, Grenoble.

The fifth conference, « Tracer 5 » moved outside Europe to the cultural heritage village of Tiradentes in the state of Minas Gerais in Brazil, and was arranged in October 2008. The local organizer was Centro de Desenvolvimento da Technologia Nuclear, CDTN, in Belo Horizonte, Brazil.

The sixth conference, « Tracer 6 » moved back in the north of the all continent to Oslo, the beautiful capital of Norway, and was organized in June 2011 by the Institut For Energy technology (IFE).

The seventh conference, “Tracer 7” moved for the first time in Africa, in the wonderful city of Marrakech in Morocco. It was organized in October 2014 by CNESTEN (Centre National de l’Energie des Sciences et des techniques Nucléaires), in cooperation with MORIA (Morocoo Radio-Isotrope Association).

After Oslo – Norway in June 2011 and Marrakech – Marocco in octobre 2014. The 8th edition of Tracers conferences took place in 2019 in Đà Nẵng‎, Vietnam.
