<\/p>\n\n\n\n

The USA is showing the strongest momentum toward a nuclear renaissance in decades, with tangible policy wins, the first new commercial reactor construction permit in nearly 10 years, reactor restarts underway, and regulatory reforms finally delivering after years of talk. <\/p>\n\n\n\n

However, it remains an early-stage acceleration rather than a fully realized boom: actual new gigawatts online at scale are still years away, and persistent bottlenecks in grid transmission, fuel supply, and project timelines mean the \u201cverge\u201d is real but not guaranteed without sustained execution.<\/p>\n\n\n\n

By Duggan Flanakin<\/a><\/p>\n\n\n\n

It has been more than seven years since President Donald Trump signed the Nuclear Energy Innovation and Modernization Act (NEIMA) into law \u2013 and it has taken all seven years (including four during the Biden Administration) for the Nuclear Regulatory Commission to issue a final rule implementing its provisions.<\/p>\n\n\n\n

Even\u00a0The Washington Post<\/em>\u00a0admits<\/a>\u00a0that the new Part 53 rules, intended to reduce review times from decades to 18 months or less, will make President Trump\u2019s goal of revitalizing the U.S. nuclear energy industry more competitive \u2013 \u201cto everyone\u2019s benefit.\u201d<\/p>\n\n\n\n

The old NRC permitting review process was built around light-water-cooled reactors (like the Westinghouse AP1000) and included prescriptive safety requirements specific to those designs \u2013 not the advanced reactors of all sizes being planned and built today.<\/p>\n\n\n\n

Many nuclear companies are designing reactors that use liquid metals (like molten salt) or gases as coolants, enabling them to operate at higher temperatures. These reactors are ultimately safer than the (still very safe) water-cooled reactors, as they rely on natural forces like gravity or convection rather than pumps and motors to automatically stop the reactor in case of an incident.<\/p>\n\n\n\n

The NRC says its final rule responds to NEIMA by creating an alternative, technology-inclusive regulatory framework that can accommodate licensing of future commercial nuclear plants, including advanced reactor designs that may not employ light-water technology. The new rules will hopefully expedite permitting of small modular reactors, microreactors, and even full-size reactors already under development.<\/p>\n\n\n\n

The NRC says its alternative requirements and implementing guidance incorporate technology-inclusive approaches and risk-informed and performance-based techniques to ensure an equivalent level of safety to that of operating commercial nuclear plants. Part 53 is designed to provide optionality and flexibility for licensing and regulating a variety of technologies and designs for commercial nuclear reactors.<\/p>\n\n\n\n

Not everyone is convinced that an agency with a lifelong track record of thwarting nuclear reactor permits has fully reformed. Noting that the real timeframe for the Part 53 rules is decades (not just 7 years), nuclear energy advocate Steven Curtis says \u201cIt\u2019s hard to imagine the NRC being objective enough to lessen the burden for licensing, even for safer SMRs. The NRC sees its mortality in simplifying their process, so what is their incentive?\u201d<\/p>\n\n\n\n

NANO Nuclear Energy CEO James Walker calls the new Part 53 rules \u201ca bridge to fleet deployment,\u201d in that it does not fully eliminate site-specific licensing, environmental review installation review, or lifecycle issues around refurbishment, refueling, decommissioning, and relocation,\u201d all needed for the microreactor industry. The NRC is reportedly developing guidance and another round of rulemaking \u2013 suggesting that Part 53 is foundational, not final.<\/p>\n\n\n\n

The proof of a reformed NRC, if indeed it is now eager to move permits forward, will soon be made evident. Previous Presidents waited in vain. Trump waited 7 years for Part 53 regulations; the real microreactor rules have yet to be formally proposed.<\/p>\n\n\n\n

More evidence that the Trump administration is serious about a nuclear energy revival comes from the National Reactor Innovation Center (NRIC), which\u00a0announced<\/a>\u00a0last week that its Demonstration of Microreactor Experiments (DOME) test bed is now complete. This first-of-its-kind facility, located at Idaho National Laboratory (INL), will enable the rapid development, testing, and demonstration of privately developed advanced nuclear reactors.<\/p>\n\n\n\n

The Department of Energy says DOME is an actual 100-foot-tall dome that is 80 feet in diameter \u2013\u00a0large enough<\/a>\u00a0to provide a safe environment to test experimental reactor concepts and gather performance data for use in informing future commercial licensing applications. Its completion dovetails with the new Part 53 NRC rules \u2013 as the U.S. seeks to accelerate the development and demonstration of advanced nuclear technologies.<\/p>\n\n\n\n

Built from the repurposed Experimental Breeder Reactor-II containment structure, DOME will help reactor developers accelerate testing timelines \u2013 saving money and reducing project risk \u2013 and hopefully deployment timelines.<\/p>\n\n\n\n

These microreactors are designed to be factory-built and portable, able to be placed in remote communities or to respond to natural disasters but perhaps primarily to serve independent microgrids (such as data centers), field-level military operations, and even space travel.<\/p>\n\n\n\n

DOME is the only test bed in the world specifically designed to host fueled microreactor experiments that can generate up to 20 megawatts of thermal energy that can be used as heat or converted to electric power. [This is comparable in size to the reactors that have powered America\u2019s nuclear submarines ever since the\u00a0USS Nautilus<\/em>\u00a0was deployed in 1954.]<\/p>\n\n\n\n

DOE Deputy Assistant Secretary for Nuclear Reactors Dr. Rian Bahran says the DOME is a vital component of reestablishing U.S. leadership in advance nuclear technologies \u2013 yet one wonders how many decades ago such a facility could have been built. Nuclear submarines can operate for 20 to 30 years without refueling, whereas conventional subs need refueling several times a year.<\/p>\n\n\n\n

Better late than never \u2013 the DOME has already started a scheduled year-long test of Radiant Industries\u2019 Kaleidos Demonstration Unit, a microreactor that uses TRISO fuel and is cooled by helium to produce 1 MW of electrical power or 3.5 MWt of thermal power. The U.S. Air Force is but one entity awaiting authorization for deploying Kaleidos. Other companies are queuing up to test their designs in DOME.<\/p>\n\n\n\n

With the DOE envisioning nuclear megacities for such activities as uranium enrichment and fuel fabrication, at least four states have announced their willingness to serve as hosts even if managing high-level nuclear waste is part of the commitment. Idaho and Tennessee have long-term experience in nuclear energy, while Utah and Nebraska are looking at the jobs and revenues to be gleaned from joining the nuclear community.<\/p>\n\n\n\n

By contrast, Nevada has fought against managing nuclear waste and Texas and New Mexico have also objected to private interim nuclear waste storage (despite Texas\u2019 push for nuclear energy development).<\/p>\n\n\n\n

Meanwhile, the U.S. continues\u00a0its ban<\/a>\u00a0on reusing nuclear waste to power reactors designed to burn (and thus dramatically reduce the volume of) nuclear waste by 95% and dramatically lower the cost of nuclear energy generation while virtually eliminating the controversial issue of nuclear waste storage.<\/p>\n\n\n\n

Of course, a major increase in the number of nuclear power plants in the U.S. will necessitate a major increase in the supply of nuclear fuel \u2013 and there is good news on that front as well. Newly launched FluxPoint Energy\u00a0announced<\/a>\u00a0it is developing what would be the first new uranium conversion facility in the U.S. in 70 years.<\/p>\n\n\n\n

FluxPoint says its mission is to \u201cestablish a fully American, vertically integrated nuclear fuel capability \u2013 supporting energy independence, enabling advanced reactor development, and strengthening national security.\u201d Development of the facility, which will convert uranium oxide (U3<\/sub>O8<\/sub>) into gaseous uranium hexafluoride (UF6<\/sub>) that can be enriched in fissile uranium-235 for use as nuclear fuel, is \u201cwell under way.\u201d<\/p>\n\n\n\n

For that matter, these and other developments \u2013 and a reinvigorated nuclear energy industry \u2013 are signs that the U.S. is \u201cwell under way\u201d to restoring its faith in a future and a renaissance already signified by the highly successful and warmly received Artemis II mission to the moon, another area of American excellence that was put into mothballs for decades.<\/p>\n\n\n\n
