It’s not all bad news from Michigan. While it may not make up for the closing of Covert, Mich.’s Palisades nuclear plant, the state’s House of Representatives last week easily approved legislation that calls for a feasibility study to examine the potential for new nuclear generation.

Introduced on April 14 by Rep. Graham Filler (R., 93rd Dist.), House Bill 1609 passed the chamber 85–20 on May 19 (just one day prior to Entergy’s announcement that it closed Palisades 11 days before its scheduled retirement). Now in Senate hands, the measure instructs the Michigan Public Service Commission to engage an outside consulting firm to conduct the study.

Should the bill become law, the commission must deliver a report on the study to the governor and congressional leadership within 18 months.

McMaster University, Ultra Safe Nuclear Corporation (USNC), and Global First Power (GFP) have embarked on a new partnership to study the feasibility of deploying a USNC Micro Modular Reactor (MMR) at McMaster University or an affiliated site. The three partners last week announced a memorandum of understanding that will support research on advanced reactor and small modular reactor technologies in support of Canada’s Net-Zero Emissions by 2050 goal.

The Finnish public’s support for nuclear power is at an all-time high, according to a recent opinion poll conducted by Kantar Public, a London-based consulting and research firm.

Commissioned by Finnish Energy—the trade association for Finland’s energy sector—the poll finds that 60 percent of respondents have either a “fully positive” or “mainly positive” perception of nuclear power as an energy source (34 percent and 26 percent, respectively), up from 49 percent in a 2021 Kantar poll.

The National Nuclear Security Administration announced last week that it is canceling its November 2020 contract solicitation for management and operation of the Pantex Plant and Y-12 National Security Complex and terminating the contract award announced in November 2021 for the two sites. The NNSA intends to hold two new competitions for separate contracts to manage each site.

Despite last month’s strong (and many might say overdue) expression of interest from Michigan Gov. Gretchen Whitmer in extending the operational life of the Palisades nuclear power plant via the Department of Energy’s new Civil Nuclear Credit Program, the facility’s 777-MWe pressurized water reactor was removed from service last Friday—11 days prior to its scheduled May 31 retirement date.

Interest in reducing carbon emissions around the world continues to climb. As a complement to the increasing deployment of variably generating renewables, advanced nuclear is commonly shown in net-zero grid modeling for 2050 because it represents firm electricity production that can flex in output with load demands.¹ However, these projections are challenged by the high levelized cost of electricity associated with legacy nuclear construction, which is often more than double that of modern combined-cycle gas turbine (CCGT) plants.

The U.K. government is providing £120 million (about $149.9 million) for a new fund designed to support the development of new nuclear energy projects, stimulate competition in the industry, and unlock investment.

Penn State University has announced plans to explore siting a Westinghouse Electric Company eVinci microreactor on its State College campus in central Pennsylvania. Under a memorandum of understanding to perform research and development work that could advance the future commercial deployment of eVinci, a team of researchers in Penn State’s Ken and Mary Alice Lindquist Department of Nuclear Engineering also plans to explore how eVinci could displace some fossil-fueled energy sources on campus.

The Department of Energy’s semiautonomous National Nuclear Security Administration funds three university–national laboratory consortia: the Consortium for Enabling Technologies and Innovation (ETI), led by the Georgia Institute of Technology in Atlanta; the Consortium for Monitoring, Technology, and Verification (MTV), led by the University of Michigan–Ann Arbor; and the Nuclear Science and Security Consortium (NSSC), led by the University of California–Berkeley. All three consortia are involved in education and research related to nuclear security and nonproliferation.

The Defense Innovation Unit (DIU), a Department of Defense organization focused on swiftly putting commercial technology to use in the U.S. military, has awarded contracts for two nuclear technologies—compact fusion and radioisotope heat—for spacecraft that could carry a high-power payload and freely maneuver in cislunar space. The objective is to accelerate ground and flight testing and launch a successful orbital prototype demonstration of each approach in 2027.

The Department of Energy today announced an extension to its deadline for applications and sealed bid submissions under the $6 billion Civil Nuclear Credit (CNC) Program, launched earlier this year.

According to the DOE, owners and operators of nuclear power reactors most at risk of premature retirement due to economic difficulties have 47 more days to submit applications for certification and sealed bids for credits. The deadline for the first CNC award cycle, originally set for tomorrow, is now 11:59 p.m. MDT on July 5.

A team from the Department of Energy’s Office of Nuclear Energy joined ANS Executive Director/Chief Executive Officer Craig Piercy on April 27 for an ANS members–only online event to discuss the Biden administration’s fiscal year 2023 NE budget proposal. The proposed total for the office, $1.675 billion, is more than a $20 million increase from the FY 2022 enacted level of $1.654 billion.

The Department of Energy’s National Nuclear Security Administration is establishing an Energy Resilient Infrastructure and Climate Adaptation (ERICA) initiative, which will help position it to deal with climate issues. In a recent press release, the NNSA noted that ERICA will help it to meet the requirements of federal legislature and executive orders, along with the DOE’s climate adaptation, energy resilience, and sustainability goals in support of the agency’s national security missions.

The initiative was outlined in President Biden’s fiscal year 2023 budget request for the DOE.

The Versatile Test Reactor, a custom-designed sodium-cooled fast neutron spectrum test reactor, is one step closer to its goal of providing data to accelerate research, development, and demonstration of diverse advanced reactor designs. The Department of Energy released the Final Versatile Test Reactor Environmental Impact Statement (Final VTR EIS) on May 13, and 30 days after its anticipated May 20 publication in the Federal Register, the DOE will issue a Record of Decision on the project.

Microreactors upend the traditional economics of nuclear power plants by shifting the paradigm from economies of scale (large reactors) to economies of multiple (mass production). While shrinking power output per unit may increase costs per kilowatt compared to large plants, offsetting gains can be expected from simplified and standardized designs, factory fabrication, inherent safety, lower radionuclide inventories, fast installation, and low financing costs. For instance, the lower power density in a microreactor core leads to a greatly reduced decay heat source, simplifying emergency cooling needs. These design aspects can lead to innovations including substantial simplifications to safety and control needs, minimized human operational requirements, a very compact balance of plant, the ability to fabricate almost every component in a factory, shortened construction time, and less daunting financing.

The Massachusetts Institute of Technology’s Plasma Science and Fusion Center (PSFC) recently announced it will expand its involvement in fusion energy research and education under a new five-year agreement with Commonwealth Fusion Systems (CFS), a fusion energy company that got its start at MIT and is now building what it says will be the world’s first net-energy fusion machine—the demo-scale SPARC.

“CFS will build SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” said PSFC director Dennis Whyte in describing the collaboration.

The United States has just 93 operating power reactors at this writing. The fleet last numbered 93 in 1985, when nuclear generation topped out at 383.69 TWh, less than half of the 778.2 TWh produced in 2021.

While the 93 reactors operating today have more capacity, on average, than in 1985, most of that increased productivity is down to operational improvements that pushed the fleet’s average capacity factor from just 57.5 percent in the three-year period 1984–1986 to near 90 percent by the early 2000s.

U.K. nuclear services company Cavendish Nuclear has signed a memorandum of understanding with U.S. reactor and fuel-design engineering firm X-energy to act as its deployment partner for high-temperature, gas-cooled reactors (HTGRs) in the United Kingdom.

Headquartered in Rockville, Md., X-energy is the developer of the Xe-100, an 80-MWe reactor with a modular design permitting it to be scaled into a “four-pack” 320-MWe power plant. As a pebble bed HTGR, the Xe-100 would use TRISO particles encased in graphite pebbles as the fuel and helium as the coolant.

According to a May 11 joint statement from the companies, development and deployment of HTGRs in the United Kingdom would support an increase in the nation’s energy security, contribute toward the government’s net-zero-by-2050 commitment, and create considerable opportunities for the U.K. nuclear supply chain.
