RCC-MRx, developed especially for Sodium Fast Reactors (SFR), Research Reactors (RR) and Fusion Reactors (FR-ITER) can also be used for components of other types of nuclear facilities. It has been consider for instance in the frame of a CEN-Workshop (CEN-WS 64 - Design and Construction Code for mechanical equipments of innovative nuclear installations) in order to develop, on its basis, the...

The microstructures of components in nuclear systems exposed to high-energy particle radiation are altered during operation by various processes typically referred to as radiation damage. The microstructural damage in turn alters the mechanical properties of the component, usually in a deleterious manor manifested as a loss of ductility and fracture toughness. It is critical that components...

The planned Mu2e experiment at Fermilab requires a high-Z production target to generate pions from an incoming 8kW proton beam. The refractory metal tungsten is an ideal target material since it is able to directly radiate the beam heat load to its surroundings without the need for a coolant, thus avoiding the cost of an active cooling circuit and greatly simplifying the remote target exchange...

HiRadMat (High Irradiation to Materials), constructed in 2011, is a facility at CERN designed to provide high-intensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies can be tested. The facility uses a 440 GeV proton beam extracted from the CERN SPS with a pulse length of
up to 7.2 s, to a maximum pulse energy of 3.4 MJ (3*10^13...

The Facility for Rare Isotope Beams (FRIB) is a new national user facility for nuclear science, funded by the Department of Energy Office of Science (DOE-SC) Office of Nuclear Physics, and under construction at Michigan State University (MSU), East Lansing, USA. FRIB will provide intense beams of rare isotopes by making use of an in-flight production technique employing a superconducting...

Beryllium is one of the candidate materials for beam windows and target components in the new high intensity, multi-megawatt proton accelerator particle sources. An international research project Radiation Damage In Accelerator Target Environments (RaDIATE) was recently launched in order to explore radiation damage issues in materials under the relevant environment and investigation of...

This work summarizes our latest results on ion-induced degradation of thermal diffusivity and mechanical response of carbon materials for production targets and beam catchers applications in high power accelerator facilities. Investigated materials include graphitic grades like high-density isotropic graphite, flexible graphite and carbon- carbon composites. Irradiations have been performed at...

Radiation Damage and Material Limits
Contributed Focus Session Oral Presentation
Techniques for extracting mechanical property information from small volumes of material have been in existence for many years. A good fraction of the development has occurred in the radiation effects community due to a desire to limit exposure to radioactive material, and/or due to limited amounts of irradiated material. Some existing test methods continue to be refined, and new methods are...

Alloy 718 is commonly used as a vacuum beam window for numerous high energy accelerator-based facilities. Specifically, at Los Alamos National Laboratory, it is used for the Isotope Production Facility and the Lujan Center at the Los Alamos Neutron Science Center. Recently, the beam window for the Isotope Production facility was replaced after 5 years of operation. To determine the usable...
