Differences in the Raman spectrum of the crater wall in samples with and without gold nanorodsFigure 3 compares the normalized Raman spectra recorded in a non-irradiated spot and on the crater wall of doped (UDMA-Au1) and undoped (UDMA-X) samples. Between 1400 and 2000 cm-1 all the spectra are dominated by the characteristic Raman peaks of the UDMA:TEGDMA polymer8. A closer look shows, however, that in the spectrum of the crater walls the bands at 1640 and 1715 cm-1 (and also at 1400 cm-1) decrease remarkably, and this effect is more pronounced for the higher pulse energies. These peaks are related to C = C and C = O…

Deep Fission has announced the installation of an underground 15 MWe modular nuclear reactor at Great Plains Industrial Park in Parsons, Kansas. The project is part of the Department of Energy’s (DOE) Reactor Pilot Program, an accelerated framework aimed at quickly authorising demonstration reactors on industrial sites. The reactor will be buried 1.6 km deep in a 30-inch borehole, with criticality targeted for July 4, 2026. Borehole-based architecture using oil and geothermal components The Gravity model developed by Deep Fission is based on a conventional pressurised water reactor (PWR) design, combined with a deep vertical borehole installation. The design uses…

GREIFSWALD, GERMANY – OCTOBER 29: A worker explains a photo taken about a year and a half ago that shows construction of the interior plasma chamber of the Wendelstein 7-X experimental fusion reactor at the Max Planck Institute for Plasma Physics on October 29, 2013 in Greifswald, Germany. Scientists hope to heat a miniscule amount of hydrogen to 100 million degrees in order to melt the atomic cores into helium, thereby releasing large amounts of energy in a similar way as the sun. Due to be completed in 2014, the reactor could help scientists to get closer towards creating atomic…

Deep Fission is leading an unprecedented undertaking in the energy industry by opening the world’s first underground nuclear facility in Kansas. Their radical new ‘Gravity Reactor’ is transitioning the industry. This will be the first facility exceeding the nuclear developmental boundaries of the foregoing ground reactors. American nuclear technology: The future of electricity supply? Deep Fission is an American nuclear technology company and is working on an underground 15-Megawatt Electric (MWe) reactor that will supply clean and economically reliable electricity to industrial customers and other critical infrastructure in the area. Unlike other reactors, Deep Fission has designed and engineered a…

Plasma is a non-equilibrium system of strong nonlinearity that provides rich phenomena for modern physics. One such physical topic is the roles of fluctuations and turbulence in the structural formation and dynamics of plasmas. Particularly, in the research of magnetically confined plasmas, various phenomena associated with turbulence have been found and investigated, especially in the research of magnetized plasma for realizing a nuclear fusion reactor. The phenomena include the non-local transport1,2,3,4,5,6 the global linkage of the turbulent activity7,8,9turbulence spreading and avalanche10,11,12,13,14,15,16which are thought to be caused by nonlinear interactions between disparate scale fluctuations covering the entire plasma17,18. The investigation of…

PARSONS — Ground was broken on the world’s first mile-deep nuclear reactor Tuesday afternoon in Parsons. Deep Fission, an advanced nuclear energy company founded in 2023, is building the reactor as part of the U.S. Department of Energy’s Reactor Pilot Program. It is the company’s first project.The concept is relatively simple. A mile-deep borehole will be drilled, and a pressurized water reactor will be placed at the bottom. The hole will be sealed and filled with water, with the reactor transferring heat to water that rises to the surface, becoming steam that turns turbines. The steam then cools down and…

The model presented here combines a database of primary damage configurations obtained through MD simulations with the PKA distribution given by a BCA code to generate the material damage produced by highly energetic ions in an efficient way.We focus our research on self-ion irradiation of Fe and W, both corresponding to body-centered cubic (bcc) crystal structures, since they are widely used and because of our particular interest in fusion reactor structural materials. Therefore, the parameters and results below correspond to them.Binary collisions approximation codeFor the BCA component of our model, we utilise SRIM31,32,33, a commonly used programme to calculate the…
