RSV TAPIRO and TRIGA RC-1 research reactors activities

Neutrons produced by research reactors have an important role in the development of nuclear science and technology and also in education and training on these applications. These facilities, originally constructed during the ‘60 s and ‘70 s decades, were initially used for the national nuclear program, then their original mission was converted to host the activities correlated with the neutrons and gamma radiations. The increasing interest in neutron radiation damage analysis, due to the very...

Assessing social impacts and Energy Justice along green hydrogen supply chains: a capability-based framework

This paper presents a comprehensive and versatile framework for assessing the social impacts and energy justice concerns of green hydrogen supply chains using a capabilities and human rights-based approach. As global efforts to decarbonise the energy sector accelerate, green hydrogen emerges as a key component to replace fossil fuels, achieve energy security and meet climate targets. Despite its potential, the transition to a hydrogen economy must address significant social justice challenges...

Activation of the visual system by space radiation: A novel study on Ca2+ signalling in ex-vivo rabbit eyes exposed to visible light, X-rays and high-energy protons

Space radiation interactions with the visual system have been the subject of many investigations, starting from astronauts reporting the perception of light flashes (visual illusions in absence of light stimuli). These perceptions have been attributed to single-ion hits, able to induce an electrophysiological response in the eye. Searching for a more general mechanism of radiation interaction with cortical neuronal networks and with sensory systems, a valuable hypothesis is that of the pertur...

The Thomson Scattering System for DTT (Divertor Test Tokamak) edge-pedestal

The preliminary design of the Thomson Scattering (TS) System devoted to the measurement of the electron density and temperature in the edge-pedestal region of DTT (Divertor Tokamak Test) is described. The evaluation of the DTT pedestal width based on the presently elaborated models tested on JET and DIIID (EPED1 model) leads to a pedestal width Δ = 10 mm along a radial line of sight on the equatorial plane, assuming a scenario with maximum core temperature Te = 20 keV and density ne = 5 1020 ...

Recovery of metallic gold, silver and copper from end-of-life mobile phones by hydrometallurgy

The global amount of end-of-life mobile phones is increasing over the years and their proper valorization is nowadays of strategic importance. Mobile phones can be considered as an important source of valuable materials, such as metals, plastics, and glass, which can be recovered and reintroduced into new production cycles. In this paper, a recovery process based on selective materials’ separation and hydrometallurgy was proposed. After manual dismantling followed by the separation of the dif...
