Workshop N°1:

The coupling of experiments and modelling to enhance experiments in research reactors

Date: Monday, 17 June 2019

Workshop conveners:

Abstract: In-pile experiments and associated studies require accurate measurements in order to enhance the understanding of complex phenomena and behaviors of materials and fuels under extreme nuclear conditions. The coupling of experiments and numerical simulations is crucial at different phases: design, development, tests under laboratory conditions, calibration, qualifications under real conditions, data analysis and interpretations after irradiations inside a research reactor, optimizations.

The workshop will be dedicated to various works focusing on

  • New mock-ups, multi-sensor probes, loops, irradiation devices for material study and characterization

  • Innovative radiation detectors (neutron, photon fluxes)

  • Innovative sensors for measurements of key parameters, conditions, phenomena (temperature, nuclear heating rate, fission gas release, mechanical or thermal properties, …)

  • Measurements during irradiation campaigns

  • Dosimetry

The different talks will deal with experiments under laboratory and under real conditions and with numerical works dedicated to various aspects such as thermal and material sciences, mechanics, thermohydraulics, ray-matter interactions. The workshop will show advancements in instrumentation, measurement methods and phenomena thanks to the coupling of experimental and numerical works.

Workshop N°2:

Wide-band gap radiation detectors

Date: Monday, 17 June 2019

Workshop conveners:

  • Takeshi Ohshima (National Institutes for Quantum and Radiological Science and Technology, Japan, ohshima.takeshi@qst.go.jp) and

  • Ivana Capan (Rudjer Boskovic Institute, Croatia, capan@irb.hr)

Abstract: Nowadays, radiation detectors are used in wide variety of fields, such as space, nuclear and accelerator facilities, medical equipment and border security. High reliability and long lifetime are demanded for radiation detectors even in harsh environments (high radiations and high temperature). Wide band-gap semiconductors such as silicon carbide (SiC) and diamond are expected to be used for radiation detectors with extreme radiation hardness. However, it is not easy to realize the wide band-gap semiconductor radiation detectors since crystal growth techniques and device fabrication process are not yet fully established. Thus, we have to consider both the development of high performance radiation detectors (initial characteristics) and their radiation tolerance when we use new materials.

In the workshop, we will discuss recent progress of the initial performance of radiation detectors based on the wide band-gap semiconductors including a new concept for high performance (new design and advanced fabrication process). Also, the radiation hardness of wide bandgap semiconductor radiation detectors will be discussed including the radiation-induced defects and their evaluation techniques. In addition, future perspective for the wide bandgap semiconductor radiation detectors will be discussed, from materials to their respective applications.

Workshop N°3:

Optical fiber technology in nuclear field

Date: Monday, 17 June 2019

Workshop conveners:

  • Patrice Mégret (University of Mons, Faculty of Engineering, Electromagnetism and Telecommunication Department, Belgium, Patrice.MEGRET@umons.ac.be)

Abstract: Optical fiber technology is more and more studied for its use as transmitting element or as sensors in nuclear industry. The reason for this extensive research work comes from the optical fiber insensitivity to electromagnetic pulses and interferences as the key material is amorphous silica glass (SiO2) or more recently polymer materials. Moreover, the low weight and small dimensions of the fibers make them also very attractive for space applications and reduce the quantity of waste after nuclear power plant dismantlement. This workshop aims to survey the possibilities and advanced in metrology in the nuclear field with optical fibers and related components like fiber Bragg gratings.

Contribution to the following topics (but not limited to) are welcome:

  • Silica-based optical fibers properties under gamma and X radiation

  • Polymer-based optical fibers properties under gamma and X radiation

  • Fiber Bragg gratings for sensing in nuclear field

  • Distributed metrology relevant to nuclear field (in power plant, in waste disposal site, ….)

  • Dosimetry based on optical fibers

  • Data transfer in harsh environment
