Nuclear NewsNEW Finding a nuclear nicheResearchers at the University of South Carolina are maintaining a comprehensive database and providing specialized material testing for molten salt nuclear reactors. Led by engineering professor Ted Besmann, the facility supports developers, national laboratories, and safety regulators across the nuclear industry. Molten salt reactors dissolve uranium in liquid mixtures, eliminating high-pressure water loops and reducing risks associated with traditional solid-fuel plants. As utilities seek smaller, scalable power sources to meet rising electricity demand, specialized thermodynamic data and testing services help accelerate commercial deployment timelines. A one-of-a-kind database and specialized testing are making USC a destination for an emerging nuclear technology. If you want to build,...
Nuclear NewsNEW Deep Fission and Youngquist Brothers Announce Collaboration on Deep, Large-Diameter Borehole DrillinDeep Fission and Youngquist Brothers are partnering to develop specialized drilling methods for underground small modular reactor installations. The collaboration leverages commercial drilling expertise to construct the deep, wide boreholes required for housing pressurized water reactors about a mile underground. The companies recently completed an equipment demonstration in Florida using a full-size prototype canister. FORT MYERS, Fla., September 21, 2026--Deep Fission, Inc. (Nasdaq: FISN) ("Deep Fission" or the "Company"), an advanced nuclear energy company working to place small modular pre...
Nuclear NewsNEW Idaho researchers develop new tool to advance nuclear research, nonproliferation missionsIdaho National Laboratory installed a mobile nuclear fuel chopping and decladding platform at its Moran facility. The modular system crimps, peels, and chops fuel rods to expose uranium cores for analysis. Researchers successfully completed the first radioactive test using actual Magnox fuel rods in May. Funded by the National Nuclear Security Administration, the equipment supports advanced fuel cycle development and nonproliferation missions. The adaptable hardware accommodates various fuel geometries and incorporates high-speed monitoring systems. This capability expands domestic processing...
Nuclear NewsNEW Progress Report on Palisades’ March to StartupHoltec International began loading fuel into the Palisades reactor vessel on August 30, 2026, entering Mode 6. During the process, a fuel assembly tilted, prompting a root cause evaluation and preparations for retrieval. Meanwhile, the plant successfully reconnected to its high voltage switchyard on September 11. The single unit, 767 megawatt facility remains offline as operators address the fuel handling event and complete required system testing. Progression toward commercial operation depends on resolving the affected assembly and securing necessary regulatory approvals from the Nuclear Reg...
Nuclear NewsNEW Georgia Power agreement with Google to provide approximately $900 million in projected benefits for Georgia Power filed an agreement with state regulators in which Google will subscribe to planned nuclear uprates at Plants Hatch and Vogtle. The arrangement adds roughly 96 megawatts of capacity while generating about $900 million in projected customer benefits. The proposal introduces a new tariff structure allowing corporate buyers to fund capacity increases and receive zero-emission credits in return. This model provides a financial pathway for utilities to expand generation at existing reactors while shielding non-participating ratepayers from incremental costs associated with the upgrades...
Nuclear NewsNEW Kairos Power and Samsung C&T Agree to Pursue Strategic Investment and Collaboration for KP-FHR DeploKairos Power and Samsung C&T Agree to Pursue Strategic Investment and Collaboration for KP-FHR Deployment | Kairos Power Samsung C&T agreed to provide up to 100 million dollars in direct investment and engineering services to Kairos Power. The funding supports the Hermes 2 demonstration plant in Oak Ridge, Tennessee. Additionally, Samsung joined the integrated engineering, procurement, and construction team for future reactor deployments. The partnership combines Kairos Power's fluoride salt-cooled reactor technology with Samsung's global construction experience. The collaboration aims to impr...
Nuclear NewsNEW TerraPower, Bechtel part ways on Natrium projectTerraPower and Bechtel ended their partnership on the Natrium reactor project after failing to agree on terms for the next phase. The split prompted Bechtel to file a WARN notice indicating potential layoffs for approximately 200 workers in Virginia. TerraPower stated that the transition will not alter the 2030 construction completion schedule for the Wyoming facility, and the engineering contract will be rebid. Engineering, construction, and project management firm Bechtel will no longer be involved with TerraPower’s Natrium power plant project in Kemmerer, Wyo., after the two companies were...
Nuclear NewsNEW The Navy Dropped Atomic Bombs on More Than 90 Ships. The ‘Ghost Fleet’ Is Still ThereThe Navy Dropped Atomic Bombs on 90+ Ships. The ‘Ghost Fleet’ Is Still There Eighty years after Operation Crossroads, dozens of warships remain at the bottom of Bikini Atoll. The United States Navy assembled more than ninety vessels for the 1946 atomic bomb tests, sinking historic carriers, battleships, and submarines in the lagoon. These submerged hulks offer a physical record of early nuclear weapons effects on naval architecture and equipment. The tests also forced the permanent displacement of local residents and introduced widespread radioactive contamination, establishing early precedent...
Nuclear NewsNEW Hanford’s TSCR system restarted after extended downtimeOperations resumed at the Hanford Site after storage Tank AP-106 gained sufficient capacity to accept additional processed material. The system had been idle for six months because the receiving tank was too full to handle more low-level waste. Site managers noted that the bottleneck supports proposals for a dual glass and grout disposal strategy to prevent future operational delays. Earlier this week, the Tank-Side Cesium Removal (TSCR) system at the Department of Energy’s Hanford Site near Richland, Wash., returned to service following a pause in operation that began on February 25. The syst...

GeneralShift Test Engineer Career PathsI am doing my Shift Test Engineer initial qualification at a public shipyard. I'm going to complete my STE qualification but I have some doubts as to whether I am going to stay at this shipyard long-term. If after completing my initial qualification, I decide to go to a different shipyard, will I take my STE qualification with me and only have to cross-qualify to my new yard' platform(s) or will I be starting from scratch initial qualifying again?If I decide to go the commercial route, what are good departments for former STEs besides operations?
