The first university-based molten salt research reactor (MSRR) is one step closer to reality with Abilene Christian University’s Nuclear Energy eXperimental Testing (NEXT) Laboratory recently signing a contract with Teledyne Brown Engineering. After considering more than a dozen engineering firms, the NEXT Lab selected Teledyne Brown to perform the front-end engineering and design work to produce the reactor on the Abilene campus. The contract was described by NEXT Lab director Rusty Towell as “a significant step into the detailed design and construction phase of this project.” The hope is that the 1-MWt MSRR will go critical in 2025.

“If we’re serious about dealing with climate change, then we’re going to need all the tools in the toolbox, which includes nuclear, not just now but in the future,” Keith Schue, an electrical engineer affiliated with Nuclear New York is quoted as saying in an article on the (Lower Hudson Valley) Journal News website, lohud. Schue adds, “We do believe that closing Indian Point was a mistake. But are we going to continue making mistakes or can we learn from them?”

The Nuclear Regulatory Commission needs to “add security features to its licenses to make it harder for people to use a fraudulent license to purchase radioactive material,” which could then be used to make a “dirty bomb,” according to a Government Accountability Office report exclusively obtained by NBC News. The recent report was publicly released on the GAO website.

A dirty bomb, also known as a radiological dispersal device, is a bomb made with conventional explosives to spread illicitly obtained radioactive materials, such as materials intended for generating nuclear power, conducting research, treating cancer, or sterilizing medical instruments. Such a weapon in the hands of a terrorist group or other “bad actor” could cause “hundreds of deaths from evacuations and billions of dollars of socioeconomic effects,” according Preventing a Dirty Bomb (GAO-22-103441).

The Nuclear Waste Technical Review Board has issued a report to the U.S. Congress and the secretary of energy examining the programs for managing spent nuclear fuel and high-level radioactive waste in more than a dozen countries.

The report, Survey of National Programs for Managing High-Level Radioactive Waste and Spent Nuclear Fuel: 2022 Update, is an update of a survey report issued by the NWTRB in 2009, in which the board described 30 institutional and technical attributes of nuclear waste management programs in 13 countries. Those countries, which include the United States, France, China, and the United Kingdom, account for 80 percent of worldwide nuclear power–generating capacity.

Romania’s Nuclearelectrica, the state-owned operator of the two-unit Cernavoda nuclear power plant, has awarded Candu Energy a contract to conduct design and engineering services for the facility’s Unit 1 refurbishment project, according to an announcement last week from SNC-Lavalin, Candu Energy’s parent company.

The June 2017 special report on the ANS Nuclear Grand Challenges (available online at ans.org/challenges/) identified low-dose radiation as a crucial focus area for ANS. Specifically, the challenge is to “Establish the scientific basis for modern low-dose radiation regulation.” This is particularly difficult given the long review cycles associated with International Commission on Radiological Protection (ICRP) and National Council on Radiation Protection and Measurements (NCRP) recommendations. Additionally, while the Environmental Protection Agency is tasked with issuing guidance on radiation exposure standards in the United States, responsibility for implementing and enforcing radiation protection regulations is distributed throughout the federal government. Finally, while it is accepted that tissue reactions (previously called deterministic or nonstochastic effects) exhibit a dose threshold, there is still substantial scientific debate over the shape of the dose response at low doses for stochastic effects, such as cancer. Despite these hurdles, substantial progress has been made over the past five years on the low-dose radiation grand challenge.

To provide a place for constructive conversation and exchange of ideas, I have built the website lmfbr.com. There, interested persons will find a description of the liquid metal fast breeder reactor technology and an outline of its history. The site is intended for an audience already generally familiar with light water reactors—but most particularly, it is meant to encourage comments so that the community can identify a pathway for deployment of LMFBRs through a conceptual design and institutional approach that draws upon collective experience, recent innovation, and re-visitation of approaches previously considered that have been long lying dormant. The website is also intended to suggest areas where further creative thought could be directed to improve the economic and operational performance of the LMFBR concept to make it highly competitive with LWRs.

Westinghouse Electric Company was awarded an engineering contract with Norsk Nukleær Dekommisjonering (NND) to plan the decommissioning of the country’s two nuclear research reactors, located in Halden and Kjeller. The three-year agreement includes options up to six years and is valued at up to $100 million (NOK 1 billion).

The Department of Energy earlier this year approved part one of a loan application from Holtec International for small modular reactor construction and invited the firm to apply for a loan to help build four of its SMR-160 units and grow its manufacturing capacity to produce the first wave of SMRs.

While the construction of two additional reactors at Slovakia’s Mochovce nuclear plant (Units 3 and 4) may get most of the attention, it isn’t the only major project underway there. In October of last year, plant owner Slovenské Elektrárne commenced the first phase of an effort to revitalize two of the four 125-meter-tall, Iterson-type cooling towers that serve the facility’s two operating reactors—both of which began generating electricity in the late 1990s. Towers #11 and #21 had been refurbished in 2011 and 2012, respectively. The other two, however, towers #12 and #22, had never undergone refurbishment.

Rockville, Md.–based X-energy announced yesterday that it has selected Zachry Group and a combined team from Burns & McDonnell and Day & Zimmermann to work with the company on the next phases of design and deployment for its Xe-100 small modular reactor fleet.

When the Department of Energy announced Innovation Network for Fusion Energy (INFUSE) awards earlier this month, Savannah River National Laboratory was named a recipient of two of the 18 awards. SRNL released a statement on July 19 explaining how a national lab with a long history of supporting environmental management and national security missions can lend a hand in the development of future commercial fusion power.

The European energy data-analysis company EnAppSys has released its second quarter (April–June 2022) electricity market reports: GB Electricity Market Summary and European Electricity Generation Summary. A major focus of both publications is the considerable effects of the war in Ukraine on the European energy markets. The reports also describe how the nuclear energy market in Europe during the second quarter was forced to adapt to reductions in supplies from France due to corrosion and cracking problems that prompted shutdowns in the French nuclear fleet.

The U.K. government has granted a development consent order (DCO) for EDF Energy’s proposed Sizewell C plant near Leiston in Suffolk, moving the new nuclear build project closer to a reality.

Nuclear New Build (NBB) Generation Company, an EDF Energy subsidiary, submitted the DCO application to the government’s Planning Inspectorate in May 2020, setting out the range of measures the project would implement to mitigate construction effects and maximize community benefits. The Planning Inspectorate accepted the application in June 2020 and completed its examination in October 2021. Recommendations were made to the secretary of state for business, energy, and industrial strategy this February.

California-based TAE Technologies has announced that its accomplishments with its fifth-generation fusion research reactor, Norman, have allowed it to secure sufficient strategic and institutional investments to fund the construction of its sixth-generation research reactor, Copernicus.

The 26th Annual Nuclear Generator and Supplier Executive Summit, hosted by Utilities Service Alliance (USA), was held at the Coeur d’Alene Golf and Spa Resort in Idaho from June 28 through July 1. About 375 attendees were present for this year’s meeting, themed “Nuclear’s Next Wave” which featured presentations and discussions on emerging nuclear technologies and designs, as well as an integrated tradeshow with about 50 industry suppliers exhibiting products, services, and ideas.

As part of its “Made in Ontario” strategy announced last year, Bruce Power has awarded a contract valued at C$130 million (about US$100.8 million) to BWXT Canada in support of the ongoing major component replacement (MCR) project at the utility’s eight-unit Bruce nuclear plant.

The National Academies of Science, Engineering, and Mathematics released a report in June recommending that the United States invest a total of $1.5 billion in low-dose radiation research over the next 15 years. Congress is working through the Fiscal Year 2023 appropriations process at this writing, and many in the nuclear community are hopeful that research programs that have been starved of funding and leadership will be reinvigorated and bring long-overdue clarity to questions of low-dose radiation science, policy, and regulation.

Kairos Power needs a source of high-purity fluoride salt to test its molten salt reactor design and ultimately to serve as the coolant in its grid-scale fluoride salt–cooled, high-temperature reactor (KP-FHR). As part of a cooperative development agreement with Materion Corporation, Kairos Power designed a molten salt purification plant (MSPP) that has just been commissioned at Materion’s campus in Elmore, Ohio.

Westinghouse has signed a new contract with Energoatom, Ukraine’s state-owned nuclear utility, to provide technical information in support of Energoatom’s feasibility study update for the construction of two Westinghouse AP1000 reactors at the Khmelnytskyi nuclear power plant in Ukraine.

The contract, according to Westinghouse’s announcement, advances the previously signed agreement between Westinghouse and Energoatom for the construction of two of the Generation III+ reactors at Khmelnytskyi Units 5 and 6.
