As general experimental and irradiation capabilities three planned spaces or experimental areas are currently planned in the facility: The Test Cell, the Complementary Experiments area, room 160, located just behind the Test Cell and connected with...
Of many structural materials for fusion reactors, the basic strategy of neutron irradiation data acquisition for reduced activation ferritic/martensitic steel F82H for application to DEMO reactors is presented, and a staged irradiation test plan utilizing the fusion neutron irradiation facility is described. In addition, the recent status of developmental techniques to evaluate the onset of...
IFMIF-DONES, the International Fusion Irradiation Facility-DEMO Oriented NEutron Source, is a major international project aimed at testing and studying materials under extreme neutron irradiation conditions expected in future fusion reactors. It seeks to create an environment that accurately simulates the irradiation conditions of fusion reactors, enabling researchers to evaluate material...
In order to predict irradiation effects of materials in fusion DEMO reactors with high accuracy, developing a mechanistic model is necessary based on theoretical understating the dependence of material behaviors on irradiation parameters such as irradiation temperature, dose rate and helium production rate. In this presentation, the current status of modeling and simulation research activities...

Irradiation experimental plans are being considered for testing with fusion neutron sources in QST. The multi-purpose usage of neutrons is also being considered. As a high neutron flux irradiation, the irradiation test of F82H, a reduced...
In this work, a comprehensive overview of a series of critical experiments and tests vital for the advancement of fusion reactor technologies and their qualification is given. Indeed, the qualification of these technologies is an unquestionable prerequisite for the development of fusion power plant and is essential for the licensing of fusion nuclear systems.
The resolution of the...
The are several documents regarding the issue of concrete composition in fusion program. In general, the material specifications for IFMIF/DONES need to be compliant with the materials and compositions considered for DEMO in the PPPT programme. A reference document is Material compositions for PPPT neutronics and activation analyses that guides to *Recommended chemical composition of...
Neutronics analyses performed in this work continue the task of neutron spectra assessments [1] inside the Complementary Experiments Room (CER) collimated by the Neutron Beam Tube and Shutter (NBT&S) system. The NBT&S system is developed to supply neutrons from the D-Li target of the IFMIF-DONES Test Cell (TC) to the CER (Room R160) for conducting experiments with neutron spectra variated from...
The intense flux of high energy neutrons, that will be generated at the upcoming DONES facility offers a unique possibility for material production, cross section measurements and investigation of exotic nuclear properties.
Radioactive material for samples that are interesting for nuclear astrophysics, but difficult to produce in the right amount and purity, could be made here. This enables...
Neutron imaging is a non-intrusive inspection tool of interest in many applications. The most employed technique involves thermal neutrons, in most cases from a nuclear reactor, that offer an excellent contrast for light elements, mainly hydrogen, thus complementing gamma- and X-rays. However, all these have serious limitations when dealing with large samples. In these cases, only fast (MeV)...
Neutron-induced reactions play a fundamental role in astrophysics, in particular for the understanding of the origin of the heavy elements in the Universe, which is one of the main open questions in science and a fascinating topic of research.
Thus far, most of the existing neutron-capture cross section measurements have been made on stable isotopes, with only a handful of experiments...
Cyclotron U120M in NPI CAS produce deuteron beams in the 10-24 MeV range and are they used in activation cross-section measurements and in FNG (Fast Neutron Generators). The experiences with activation measurements helped to contribute to SPIRAL2/NFS with the Pneumatic Transfer System (developed in KIT) and the Irradiation Chamber that allows to study short-lived isotopes produced in the...
Neutron-dominated mixed field irradiation testing stations at CERN are employed for scientific, technological, and industrial application. Currently operating infrastructure include the NEAR irradiation station at the n_TOF facility and a similar infrastructure at ISOLDE, called ISIS (ISOLDE Irradiation Station). NEAR is operating to the neutron time-of-flight (TOF) facility n_TOF [1] served...
The radiation environment (e.g. gamma, neutrons) can damage or destroy electronic devices or sensors, corrupt signals in analogue or digital circuits, corrupt data or programs in digital circuits (memories, microprocessors, microcontrollers, FPGAs, etc. ). These effects can appear gradually due to cumulative phenomena, or instantaneously due to a single particle (e.g. a neutron) causing a...
Particle beam radiation, and therefore neutrons, are classified as ionising radiation due to their biological effect. They can affect biological tissue in two main ways: by inducing cell death and by inducing genetic alterations that can lead to stochastic or deterministic effects in cells. Neutrons have been classified as high LET (Linear Energy Transfer) particles and, due to the large...
Most cancer patients worldwide who undergo radiotherapy are treated with megavoltage X-rays, though other forms of radiation (such as protons or heavy ions) are being incorporated to clinics. In all these treatment types, the absorbed dose is the fundamental magnitude to determine the effects of ionising radiation on both normal or tumor living tissues. However, a single relationship between...
The International Fusion Irradiation Facility-DEMO Oriented NEutron Source (IFMIF-DONES) will be an experimental facility that will provide a characteristic spectrum of high energy and intensity neutrons. Its primary functionality will be to test materials under equivalent nuclear fusion irradiation conditions to qualify them for the future nuclear fusion power plant DEMO. The material...
Nuclear medicine and radiopharmacy are two disciplines that are making great strides in the development of new radiotracers. Theragnosis with radiopharmaceuticals represents a breakthrough in increasingly targeted cancer therapies. This concept involves diagnosis and treatment with two radionuclides of the same element or related molecules with different isotopes ensuring that what you image...
The IFMIF-DONEA facility in Granada is ESFRI single-site facility. For access to research infrastructures, ain in particular ESFRI facilities, the administration for requesting and granting time should be users’ friendly and kept to a minimum, in accordance with the principles stated in the European Commissions' document „European Charter for Access to Research Infrastructures“[1]. There are...
The IFMIF-DONES Facility will be classified as a 1st Category Radioactive Facility according to the Spanish Regulations. As such, its commissioning and operation are subjected to the license permit granted by the Spanish nuclear regulatory body, Consejo de Seguridad Nuclear (CSN). The unicity and one-of-kind characteristics of IFMIF-DONES (both in Spain and worldwide) requires the development...
