The World's 500 cities over 1 million population and 4,000 cities over 100,000 thousand population are heated, cooled, and propelled by Coal Electricity plants, Oil Refineries, and Natural Gas Wells. That's a lot of CO2 Emissions.
The fastest way to decarbonize such a world is to electrify the top 4,500 cities with as much nuclear electricity as possible - about 500 12 module NuScale Reactors along with 4,000 6 or 4 module NuScale Reactor facilities.
The remainder of the world's cities, towns and villages need to be electrified by Biomass energy sourced Allam Cycle power plants to remove the legacy CO2 from the air.

What The World's Largest Cities Need Most: Modern Modular Nuclear Reactors


The stone-simple gravity-circulation NuScale Modular Nuclear Reactor Power Plant is a very safe design to install adjacent to our natural gas combustion turbine plants.
The reasons for this choice include NuScale site size, access to the existing electrical grid, roads, rail, workforce, and community acceptance.
With a full complement of 12 reactor modules, it will produce 924 megaWatts of electricity, almost twice the power of the coal and/or natural gas turbine power plants it is designed to replace.    Consider the repowering of a worn-out coal power plant with a new nuclear reactor approach:   

In some ways, Greenies are like anti-vaxxers. If Greenies were reasonable, there would be a NuScale nuclear power plant near any U.S. town that could make good use of that much electricity.

Please look again at how much uranium mankind has available.  So much uranium is available there is absolutely no reason to recycle spent nuclear fuel waste into bombs. 
Spent uranium must be buried irretrievably immediately.  In WWII, the United States used spent uranium to easily and quickly make the plutonium nuclear bomb used on Nagasaki.
This should be a warning to us to never allow plutonium to get loose.

Once through and then Subduction Disposal for nuclear.     Since all uranium used as nuclear fuel has some plutonium bred in it during the process, it must be disposed of immediately.

Nuclear Proliferation

The necessity for uranium enrichment for Light Water Reactors and the presence of plutonium in the spent fuel are the primary proliferation concerns.

There are differing national policies for the use or storage of fissile plutonium in the spent fuel, with some nations electing to recycle plutonium for use in new fuels and others electing to leave it intact within the spent fuel (IAEA, 2008a). The presence of plutonium and minor actinides in the spent fuel leads to greater waste-disposal challenges as well. Heavy isotopes such as plutonium and minor actinides have very long half-lives, as high as tens to hundreds of thousands of years (NRC, 1996), which require final waste-disposal strategies to address safety of waste disposal on such great timescales. Alternative strategies to isolate and dispose of fission products and their components apart from actinides could have significant beneficial impact on waste disposal requirements (Wigeland et al., 2006). Others have argued that separation and transmutation of actinides would have little or no practical benefit for waste disposal (NRC, 1996; Bunn et al., 2003).

Alternative nuclear fuel cycles, beyond the once-through uranium cycle, and related reactor technologies are under investigation. Partial recycling of used fuels, such as the use of mixed-oxide (MOX) fuels where U-235 in enriched uranium fuel is replaced with recycled or excess plutonium, is utilized in some nations to improve uranium resource utilization and waste-minimization efforts (OECD and NEA, 2007; World Nuclear Association, 2013).

The thorium fuel cycle is an alternative to the uranium fuel cycle, and the abundance of thorium resources motivates its potential use (see Section 7.4.3). Unlike natural uranium, however, thorium does not contain any fissile isotopes. An external source of fissile material is necessary to initiate the thorium fuel cycle, and breeding of fissile U-233 from fertile Th-232 is necessary to sustain the fuel cycle (IAEA, 2005b).

Ultimately, full recycling options based on either uranium or thorium fuel cycles that are combined with advanced reactor designs — including fast and thermal neutron spectrum reactors — where only fission products are relegated as waste can significantly extend nuclear resources and reduce high-level wastes (GIF, 2002, 2009; IAEA, 2005b). Current drawbacks include higher economic costs, as well as increased complexities and the associated risks of advanced fuel cycles and reactor technologies. Potential access to fissile materials from widespread application of reprocessing technologies further raises proliferation concerns. The advantages and disadvantages of alternative reprocessing technologies are under investigation. - from Energy Systems Chapter 7 - IPCC 5 - IPCC Working Group III - 2014.

Our initial fuel enrichment is 15-20%, making it the lowest strategic value for proliferation potential. Lightbridge Fuel™ contains significantly less plutonium than conventional uranium oxide fuel and consumes more uranium during its operating cycle. Any plutonium in our spent fuel is “useless” for nuclear weapons, according to an April 2018 issue of Nuclear Engineering and Design.


Achieving a proliferation resistant, or possibly even proliferation proof, plutonium is a goal of the nuclear security and safeguards community. Considering that nearly all plutonium is under international safeguards, with the exception of plutonium with greater than 80 at.% 238Pu, reducing the necessity of these safeguards would be beneficial to both those in industry and in national and international security. Due to the 238Pu high decay heat, establishing a technical limit for 238Pu content in which rendering the plutonium useless for weapons purposes may be possible. Following the analysis done by Kessler, the authors analyzed two realistic models for hypothetical nuclear explosive devices seeking to establish this technical limit for 238Pu content. The given plutonium vector used for this analysis was obtained through simulations of the Lightbridge fuel design in a pressurized water reactor. Calculating the temperature profile within the two hypothetical nuclear explosive device models showed that this plutonium vector would render the two models useless by causing the high explosives to undergo self-explosion.

Lightbridge Sets Priorities for SMR Fuel Development

Lightbridge Corporation (NASDAQ:LBTR) has decided to prioritize developing fuel for future small modular reactors rather than fuel for large reactor designs, President and CEO Seth Grae said this week in a business update ahead of a webcast and conference call to discuss the company’s financial results.

DOE awards $20M to project to produce clean hydrogen from nuclear power

The US Department of Energy (DOE) is awarding $20 million in funding to a project to demonstrate technology that will produce clean hydrogen energy from nuclear power. This approach will allow clean hydrogen to serve as a source for zero-carbon electricity and represent an important economic product for nuclear plants beyond electricity.

The project, based in Arizona, will make progress on DOE’s H2@Scale vision for clean hydrogen across multiple sectors and help meet the Department’s Hydrogen Shot goal of $1 per 1 kilogram in one decade.

The project, led by PNW Hydrogen LLC, will receive $12 million from the DOE’s Hydrogen and Fuel Cell Technologies Office (HFTO) and $8 million from DOE’s Office of Nuclear Energy (NE) for a total award of $20 million. The project will produce clean hydrogen from nuclear power at the Palo Verde Nuclear Generating Station in Phoenix, Arizona—the largest nuclear plant and the single-largest generator of carbon-free electricity in the US.

Six tonnes of stored hydrogen will be used to produce approximately 200 MWh electricity during times of high demand, and may be also used to make chemicals and other fuels. The project will provide insights about integrating nuclear energy with hydrogen production technologies and inform future clean hydrogen production deployments at scale.

PNW Hydrogen, LLC will be the primary recipient of the DOE award and will collaborate with multiple stakeholders in research, academia, industry and state-level government including Idaho National Laboratory, National Energy Technology Laboratory, National Renewable Energy Laboratory, OxEon, Electric Power Research Institute, Arizona State University, University of California Irvine, Siemens, Xcel Energy, Energy Harbor and the LA Department of Water and Power.


The future construction of a large-scale SOEC electrolyser production plant by Haldor Topsoe represents the cornerstone of the large-scale launch of industrial electrolysis, powered by renewable sources. Haldor Topsoe's program is in perfect synchrony with the forecasts of the Green Deal Road Map approved on 8 July 2020 by the European Community. The production of LIHC and LOHC, not a play on words, but the synthesis of green hydrogen in inorganic and organic liquid carriers, represents the only real alternative to fossil fuels. The date of 8 July 2020 will be remembered as a historic date for the entire European Community.

A Natural Gas Turbine Site Is A Good Place To Build A NuScale Nuclear Plant
Combined cycle natural gas turbines look like a good idea to fill in for wind farm electricity irregularities.

It's best to build new adjacent nuclear while old gas turbine plant

TVA CEO: Utility Will Invest in SMRs


According to wire service reports, TVA President and CEO Jeff Lyash said last week during an online energy conference hosted by the Atlantic Council that to reach the 100% reduction goal, the utility will need technological advances in energy storage, carbon capture and small modular nuclear reactors. (YouTube video) Lyash said TVA is on track to reduce greenhouse gas emissions by 80% by the year 2035.

Coal Plants Converted to SMRs?

Lyash said that the hundreds of shuttered US coal power plants could be repurposed as small nuclear reactor sites citing easy access to water resources and existing power grid connections. “I see those sites as very viable small modular reactor (SMR) sites.”

Lyash does not see coal as part of the utility’s future, saying TVA will continue to phase it out over the next 15 years because its coal plants are reaching the end of their lives.

Sen. Joe Manchin, D-W.Va., who also attended the virtual meeting, agreed, “You could come online much quicker and we could accomplish this at a much faster rate than anything else we could do.”

“Some of our better manufacturing sites are the coal-fired power plants,” said Senator Joe Manchin, a Democrat from West Virginia. “You could come online much quicker and we could accomplish this at a much faster rate than anything else we could do,” he said about the SMR potential.  - - -

NuScale & UAMPS  (Utah Associated Municipal Power Systems) Take Next Steps to License, Manufacture, and Build the First of 12 SMRs

NuScale Power has gotten the go ahead to prepare a Combined License Application (COLA) to be submitted to the Nuclear Regulatory Commission. The UAMPS COLA is expected to be submitted to the Nuclear Regulatory Commission (NRC) by the second quarter of 2023.

NRC review of the COLA is expected to be completed by the second half of 2025, with reactor construction of the project beginning shortly thereafter. NuScale expects to have the first of 8 units in revenue service before the end of the decade. Eventually, plans are for the site to have 12 SMRs. The power rating of the site is a work in progress as NuScale started with an estimate of 50 MWE, but has since increased its design objective to 60 MWe and indicated it has plans for 77 MWe.

The NuScale reference power plant can house up to 12 NuScale Power Modules for a total facility output of 924 megawatts of electricity (MWe). NuScale also offers smaller power plant solutions in 4-module and 6-module sizes with outputs of 308 MWe (gross) and 462 MWe (gross), respectively. The multi-module NuScale plant design is scalable, allowing customers to incrementally increase facility output to match demand.

NuScale Power announced this week together with Utah Associated Municipal Power Systems (UAMPS) that it has executed agreements to facilitate the development of the Carbon Free Power Project (CFPP), which will deploy NuScale Power Modules at the Idaho National Laboratory (INL).

Fluor Corporation and NuScale (as a subcontractor to Fluor) are to develop higher maturity cost estimates and initial project planning work for the licensing, manufacturing and construction of the CFPP.

 " What’s Needed to Save Funding for the Versatile Test Reactor?   (Please read - Posted on    by djysrv)

It is time for the major developers of advanced nuclear reactors, and small modular light water reactors, in the U.S. to support funding for the Versatile Test Reactor (VTR). 

The reason is that these firms will need its testing capabilities to certify that their fuels, materials, sensors, and components will work in the demanding conditions that these plants are designed to operate in.
There is no other way to do it. Self-certification either directly or with fuel and component vendors, is not a viable strategy.

Real-time measurements and post-irradiation examination techniques will provide valuable information on how fuels, materials, components and instrumentation withstand the extreme conditions inside nuclear power plants. This is crucial information needed to design, license, and build successful implementations of advanced nuclear reactors."
