PPPL develops novel X-ray crystal spectrometer to measure laser-produced high energy density plasmas in the National Ignition Facility at Lawrence Livermore National Laboratory.
The oxide dispersion strengthened copper alloy (ODS-Cu) is superior in thermal conductivity, electrical conductivity and heat resistance. Although the ODS-Cu can be expected to have various industrial applications, its joint with other materials is extremely difficult because of its intrinsic poor weldability. The research group has developed an extremely novel joint technique that enables us to fabricate any component made of ODS-Cu. This technique contributes to producing the heat removal component for the fusion reactor.
In a major scientific leap, University of Queensland researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see.
This Topical Issue of EPJ A draws together a large collection of papers inspired by the theory of hot matter and relativistic heavy-ion collisions (THOR) European Cooperation in Science and Technology (COST) Action. Running between November 2016 and April 2021, THOR has provided a way for over 300 researchers involved in heavy-ion collision analysis to freely exchange their ideas.
To realize tritium self-sustaining cycle through tritium breeding blanket has been one of the core technologies of future fusion reactor. Therefore the design and function of blanket must be validated by neutronic experiment under D-T neutron environment. But due to the scarcity of DT neutron source, and highly radioactivity during neutronic experiments, it is very difficult to validate the nuclear response of the blanket, the data of tritium production rate mainly rely on Monte Carlo simulation.
A new report finds small modular reactors could provide competitively priced electricity in Washington state's future electricity market.
When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at Fukushima-Daiichi automatically shut down, as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven't been seen since the Chernobyl disaster in 1986.
Scientists created clay bricks that are able to attenuate ionizing radiation to a level that is safe for the human body. These bricks can be used to building walls around nuclear facilities. It is cheap and environmentally friendly.
Researchers from University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the XUV spectrum to generate second harmonics on a laboratory scale. As the team writes in Science Advances, they were able to achieve this effect for the first time with a laser source on a laboratory scale and thus investigate the surface of a titanium sample down to the atomic level.
Scanning technology aimed at detecting small amounts of nuclear materials was unveiled by scientists in Sweden today, with the hope of preventing acts of nuclear terrorism.
