     Moltex Energy Limited subsidiary MoltexFLEX has announced the launch of its FLEX molten salt reactor. Through flexible operation and the use of thermal storage technology, the FLEX can support intermittent renewable energy through its rapid responsiveness to changes in demand.
     A MoltexFLEX representative said, “This advanced nuclear technology has the flexibility of gas-fired power stations, but it generates electricity at a lower cost, and without carbon emissions.”
     The FLEX reactor has no moving parts. It is simple in both design and operation. The FLEX can respond to changes in energy demand. It can automatically enter an idle state or return to full power. This makes it an ideal compliment to wind and solar power. Conventional nuclear power reactors are not able to easily and quickly change their output.
     According to MoltexFLEX, the cost of electricity generated by the FLEX reactor is comparable to the cost of wind generated electricity. This cost is roughly forty-four dollars per megawatt. This low cost is achieved by a unique, patented system which uses two molten salts. One of the salts acts as a fuel and the other circulates as a coolant. This permits the heat from the reactor to be extracted through natural convection, without the need for pumps.
     The FLEX reactor is small and modular. This allows the components to be factory-produced and readily transported. This, in turn, increases the speed of construction and minimizes overall cost. The FLEX reactor is passively safe, so it does not require engineered, redundant, active safety systems.
     Once it is online, the FLEX reactor can be operated with the same skill sets and equipment used in a fossil fuel plant. The FLEX reactor has no moving parts and can be fueled to operate for twenty years at a time. This means that there is very little operator input and very low ongoing costs.
      Each FLEX reactor delivers forty megawatts of thermal energy at thirteen hundred degrees Fahrenheit. This heat is stored in MoltexFLEX’s GridReserve thermal storage tanks. The FLEX reactor can deliver three times the power when renewables alone cannot meet the market need for electricity.
     During longer periods of renewable generation, the FLEX reactor can just move passively into idle mode. This produces just enough heat to keep the reactor at operating temperature.
     MoltexFLEX estimates that it will take just twenty-four months to construct a five hundred megawatt power plant. The company hopes to have its first reactor operational by 2029.
     David Landon is the CEO for MoltexFLEX. He said, “We recognized the need for an energy supply that can support renewables when the sun doesn’t shine or the wind doesn’t blow. In the FLEX reactor, we have a solution for consumers and countries alike. The FLEX reactor provides the safety net of affordable domestic energy but is versatile enough for applications ranging from decarbonizing heavy industry to powering cargo ships.”
     The FLEX reactor is the version of Moltex Energy’s stable salt reactor technology that is moderated by thermal neutrons. The same technology is shared with MoltexFLEX’s sister company, Moltex Energy Canada Inc. This company is developing a fast neutron version of the stable salt reactor.
     In May of 2021, the Canadian Nuclear Safety Commission completed the first phase of the pre-licensing vendor design review for Moltex Energy’s three-hundred-megawatt Stable Salt Reactor which is called Wasteburner (SSR-W 300) small modular reactor. The SSR-W is a molten salt reactor that uses nuclear waste as fuel. This company aims to deploy its first such reactor at the Point Lepreau site in New Brunswick by the early 2030s.

     Matthew Memmott is a Brigham Young University professor and nuclear engineering expert. He and his team have designed a new system for safer nuclear energy production. Their new system is a molten salt micro-reactor that may solve many problems with nuclear power.
     Unlike the current light water nuclear power reactors, Memmott’s new reactor stores radioactive materials in a liquid salt instead of fuel rods. He said, “Nuclear energy can be extremely safe and extremely affordable, if done the right way. It’s a very good solution to the energy situation we’re in because there are no emissions or pollution from it.”
      In Memmott’s new reactor, all the radioactive byproducts are dissolved in molten salt. Nuclear waste can emit heat and/or radioactivity for hundreds of thousands of years. This is why finding a safe way to dispose of nuclear waste has been so difficult. But, salt has an extremely high melting temperature of a thousand degrees Fahrenheit. Molten salt cools rapidly and will drop below that temperature very quickly. Once the salt crystalized, the radiated heat will be absorbed into the salt and does not remelt it. This negates the danger of a nuclear meltdown.
      Another benefit from the molten salt reactor is that it has the potential to completely eliminate dangerous nuclear waste. The products of the nuclear reactions are safely contained in the salt. There is no need to store them elsewhere. Many of these products are valuable. They can be removed from the salt and sold.
     Molybdenum-99 is an extremely expensive element used in medical imaging procedures and scans. It can be extracted from molten salt. The U.S. currently purchases all of its Molybdenum-99 from the Netherlands. Extraction from the new reactor would make it more accessible and affordable. Cobalt-60, gold, platinum, neodymium and many other useful elements can also be removed from the salt. These extractions could potentially eliminate nuclear waste completely. Memmott said, “As we pulled out valuable elements, we found we could also remove oxygen and hydrogen. Through this process, we can make the salt fully clean again and reuse it. We can recycle the salt indefinitely.”
    A typical commercial nuclear power reactor requires about one square mile to operate to reduce radiation risk. The core alone is thirty feet by thirty feet. Memmott’s reactor is four feet by seven feet. The new reactor can generate about a megawatt which could power around a thousand homes. Everything needed to run this reactor is designed to fit onto a forty-foot truck bed. This means that this reactor can make power accessible to even remote places.
     Other members of Memmott’s team include re BYU professors Troy Munro, Stella Nickerson, John Harb, Yuri Hovanski, Ben Frandsen, and BYU graduate student Andrew Larsen.
      Memmott remarked that “For the last 60 years, people have had the gut reaction that nuclear is bad, it’s big, it’s dangerous. Those perceptions are based on potential issues for generation one but having the molten salt reactor is the equivalent of having a silicon chip. We can have smaller, safer, cheaper reactors and get rid of those problems.”

     Morefield was also concerned about access to uranium. He said, “It’s unfortunate, but most of the world’s largest suppliers of uranium are not located in the United States. If Virginia is going to be serious about building more nuclear reactors, we must first lift the moratorium on uranium mining in Virginia.” (The biggest unmined uranium deposit in the U.S. is Coal Hill, in Pittsylvania County, Virginia. Virginia enacted its ban on uranium mining in 1982 because of concerns about environmental and public safety hazards.)
     Delegate James W. Morefield said that Republican and Democratic policy makers understand that fossil fuels will not last forever. He said, “If we are going to focus on the use of alternative sources of energy it must be done in manner that is cost effective and not a burden on people who are struggling to pay their utility bills.”
     Governor Youngkin insisted that his new Plan takes concerns about the affordability of electricity in Virginia into account. He added that, “A growing Virginia must have reliable, affordable and clean energy for Virginia’s families and businesses. We need to shift to realistic and dynamic plans. The 2022 Energy Plan will meet the power demands of a growing economy and ensures Virginia has that reliable, affordable, clean and growing supply of power by embracing an all-of-the-above energy plan that includes natural gas, nuclear, renewables and the exploration of emerging sources to satisfy the growing needs of Commonwealth residents and businesses.”
     Youngkin said that retiring baseload generation in favor of solar and wind energy would reduce Virginia’s electricity reliability. He also said, “Nuclear is nearly three times more reliable than both wind and solar. As a result, the industrial world relies on continuous baseload generators such as natural gas, nuclear and coal. Cost, technical concerns related to utility scale storage, and transmission upgrades demand prudence before removing current baseload capacity.”
     Youngkin’s Plan said that the VCEA’s mandates are an “inflexible, 30-year determination with a prescribed route that currently cannot be delivered and do not contain any guidelines ensuring reasonable energy costs for Virginian consumers.”
     Youngkin also said that the VCEA depends on Virginia outsourcing reliable baseload capacity to other states. This would increase Virginia’s dependence on electricity imports. This would result in supply and transmission of energy to Virginia homes and business having the potential to become less reliable than today. (Many of the states that could supply electricity to Virginia have a high percentage of coal and natural gas generation.)
    Terry Kilgore from Scott County is the House Majority Leader of Virginia legislature. He released a statement in response to the SMR Plan. He said, “I want to thank Governor Youngkin for the release of his 2022 Virginia Energy Plan, which outlines a reliable, affordable energy future and includes several exciting opportunities for Southwest Virginia. His endorsement of small modular nuclear reactors supports a technology that can innovate and revitalize abandoned coal mines and diversify Southwest Virginia’s economy.”
