Alexander C. Kaufman, writing in the Huffington Post, called the ADVANCE (Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy) Act "the biggest clean-energy bill since Biden's climate law." What it really is, is legislation designed to "reverse the American nuclear industry’s decades-long decline and launch a reactor-building spree to meet surging demand for green electricity at home and to catch up with booming rivals overseas." And, according to Diana DeGette (D-Colo.), a “much needed modernization of our nuclear regulatory framework.”
There are a number of very important provisions in the bill but, one of the most important is the provision which tasks the NRC with rewriting its mission statement so as to avoid unduly limiting nuclear and thereby preventing efforts to allow society to benefit from its clean power. The bill also reduces the fees charged to developers and helps speed up the process for licensing new reactors, hiring key staff and coordinating with foreign regulators to speed deployments.
The passage of the ADVANCE Act continues a long-term trend of strong bipartisan unity on nuclear-related bills, demonstrating agreement by Democrats and Republicans on the importance of expanding clean and reliable energy. The House of Representatives had previously passed its corresponding legislation by a vote of 365 to 36, strengthening and expanding upon the version passed back in July by the Senate.
“Republicans and Democrats recognize the development of new nuclear technologies is critical to America’s energy security and our environment,” Sen. Shelley Moore Capito (R-W.Va.), the bill’s lead sponsor, said on the Senate floor Tuesday evening. “Today, nuclear power provides about 20% of our nation’s electricity. Importantly, it’s emissions-free electricity that is 24/7, 365 days a year.”
“This bipartisan policy creates the framework for companies to start building that order book for a second project and a third project and ultimately get the NRC ready to license dozens per year,” said Nicholas McMurray, the managing director of international and nuclear policy at energy policy group ClearPath.
The ADVANCE Act is specifically tailored to boost the next generation of reactors being designed now, that are not currently in commercial production in the U.S. Some of these newer designs will be migrating away from water cooling and will use other types of coolants, such as liquid metal or high-temperature gas, which have a range of benefits, such as enhanced safety, allowing reactors to run on different types of fuel, producing less waste and being able to operate at higher temperatures and be sized to suit the needs of users in more settings than a traditional nuclear plant.
In recognition of these so-called fourth-generation reactor models’ unique uses and the urgency of bringing these designs to market, the bill authorizes the Department of Energy to give out financial awards to the first companies to meet specific goals, such as using fuel made from recycled nuclear waste or generating heat that could be used for industrial process heat, rather than electricity production.
Given that the Biden-Harris Administration has just announced steps to bolster the domestic nuclear industry and advance America's Clean Energy Future, it seems highly likely that Biden will sign the legistlation. Meanwhile, the DOE has also just announced that it has allocated an additional $900 million to accelerate the deployment of next-generation small modular reactors.
Together, these actions amount to laying the foundation necessary to help America finally compete with Russia and China. Speaking in support of the legislation Tuesday, Senate Majority Leader Chuck Schumer (D-N.Y.) said the bill would “support job growth, clean energy and leadership while preserving the NRC’s fundamental safety mission.'

RTO Insider has reported on the discussion at the NARUC meeting in mid-February, in which the Tennessee Valley Authority CEO, Jeff Lyash, made the case for his need for nuclear energy to achieve his goals of 80% carbon-free generation by 2035 and net-zero by 2050.
The TVA already has an early has an early site permit from the Nuclear Regulatory Commission to build its first SMR at Clinch River. But Lyash is not interested in building one reactor. “In order for us to be successful, TVA needs something on the order of 20 reactors over that period of time," Lyash remarked to those gathered at the National Associate of Regulatory Utility Commissioners Winter Policy summit in Washington, D.C.
TVA, a federally-owned utility, will still need a construction permit for the 300 MW GE Hitachi MWRX-300 SMR that it is planning to build but what Lyash really needs is for the construction to reach "nth-of-a-kind costs, supply chain, workforce, project execution" to make constructing a portfolio of 20 or more reactors and slam dunk.
The rising need for nuclear power as a critical technology to enable full decarbonization was a major theme of the NARUC conference. As such, the formation of a new initiative, the Advanced Nuclear State Collaborative, to bring together members of NARUC and the National Association of State Energy Officials was announced by David Wright, an NRC commissioner, and Tricia Pridemore, chair of the Georgia Public Service Commission. The initiative, sponsored by the Department of Energy, will provide technical assistance and expertise for states deploying or considering new nuclear projects, Commissioner Pridemore said.
The new collaborative is the response to growing interest in nuclear by energy insiders. In at least 20 states, “public service commissions and state energy offices are engaged in feasibility studies for advanced nuclear reactor site selection, strategies to reduce regulatory and policy barriers to new nuclear, and other activities to pave the way for advanced reactors,” Commissioner Pridemore said.
With the two new AP1000 reactors at Vogtle just starting to come online, one might think that the troubled Southern Co. experience of building them at more than double the original cost and six years delayed might put a damper on interest in building more nuclear. In fact, Lyash and LPO Director, Jigar Shah, agreed that Vogtle showed that "America is deciding to do big things."
As a result of completing these AP1000s, there are now 13,000 trained men and women with experience in building new power plants. They will next be deployed in building the next AP1000s in Poland, which selected the Westinghouse AP1000 in part because the Vogtle plant got done, produced valuable lessons, and there is current knowhow for building it.
Now, this experience is available to benefit all new buyers, de-risk new builds and improve the financial and public trust in the technology. If more customers step up, whether for the AP1000 or other new designs, the valuable lessons learned can actually benefit the U.S., other nations and our decarbonization efforts and help keep nuclear power competitive in general.
In fact, according to Lyash, nuclear power plants are "highly competitive." And he should know because nuclear generates 42% of TVA's power supply. So while nuclear plants require large up-front capital expenditure, "they have a tremendously long and beneficial life," per Lyash. "They also deliver all the attributes to a power system that you need—voltage, frequency and maneuverability." The key need going forward: Buidling them on time and on budget.
