Nuclear SoftwareNEW Looking for Rados softwareUpdate: I found out that Mirion bought Rados. I called Mirion and they informed me that they have discontinued the model and software. I haven't had any luck by reaching out to third parties.You're my only hope Obi-Wan :)
History & TriviaNEW The Hiroshima Atomic Blast Forged a Metal Never Seen Before on EarthGeologists led by the University of Florence have identified a previously unknown iron-chromium alloy within microscopic fallout debris from the 1945 Hiroshima atomic bombing. The 10-micrometer grain exhibits a complex, highly ordered cubic crystal structure that formed due to the extreme temperatures and rapid cooling rates of the nuclear fireball. This discovery highlights that nuclear blast debris contains a unique library of metastable materials that are difficult to replicate in laboratory settings. For the nuclear industry, these findings demonstrate that fallout particles serve as a phy...

Nuclear NewsNEW Utilities eye small modular nuclear reactors for reliability as hyperscalers drive demandTechnology companies and defense installations are leading the adoption of small modular reactors and microreactors to secure reliable, low-carbon power. Utilities are exploring these technologies through three-party agreements that share financial risk, though they remain constrained by existing grid infrastructure, long interconnection timelines, and the need for supportive state legislative frameworks. The industry is shifting from prototype testing toward commercial deployment by standardizing designs to reduce costs. While developers focus on fleet-scale construction, stakeholders note th...
Nuclear NewsNEW Opinion: Modern regulation for a new nuclear eraThe Nuclear Regulatory Commission has proposed a modernization of its radiation protection framework to replace subjective expectations with a graded, objective approach. The agency maintains that current dose limits for workers and the public will remain unchanged under the new rules. This proposal aims to provide clearer, predictable requirements for licensees. The shift seeks to replace the open-ended ALARA standard with defined thresholds to reduce regulatory uncertainty for advanced reactor developers and existing operators. By establishing technically defensible requirements, the NRC int...
