Anyone involved in the nuclear power industry could tell you that the operation of nuclear power plants is a demanding and never-ending endeavor. Our machines are complex, our challenges are diverse, and our standards are unyielding. The truth is, however, many of us stay in this field because there’s something at the heart of what we do that makes it all worthwhile.

Westinghouse has signed a contract with Rolls-Royce SMR to develop a fuel design for the British firm’s small modular reactor program, the companies announced last week.

The design work, to be undertaken in the United Kingdom and the United States, will include associated core components and will be based on an existing Westinghouse pressurized water reactor fuel assembly design.

Operating costs for nuclear units have grown significantly since the start of the commercial nuclear power industry. For nuclear power generation to remain competitive, process efficiencies and innovations will need to be introduced. The challenge for any change is to improve the safe operation of the nuclear unit. An area of opportunity to reduce operating costs while improving operational safety is through upgraded fuel design and manufacturing. At Southern Nuclear, the pressurized water reactor fuel engineering team worked with Westinghouse to implement the PRIME fuel features, where simple improvements would yield safer operation and long-term cost-savings due to a more robust fuel design. Implementing the PRIME fuel ensures that the operator’s burden from fuel performance is minimized while keeping the reactor unit in a safe operating condition.

American Centrifuge Operating (ACO), a subsidiary of Centrus Energy, has started enriching uranium hexafluoride gas to high-assay low-enriched uranium (HALEU) levels at the Department of Energy’s enrichment facility in Piketon, Ohio, the DOE announced October 11. The HALEU will be used to help fuel the initial cores of two demonstration reactors awarded under DOE’s Advanced Reactor Demonstration Program and will also support fuel qualification and the testing of other new advanced reactor designs.

It’s late March 2023, and freshman state Rep. Stephanie Barnard (R., 8th Dist.) moves quickly through the halls of the capitol building in Olympia, Wash. She enters a room packed with state legislators—both Democrats and Republicans—who are waiting for a meeting to begin.

The event is part of the recently formed Nuclear Energy Caucus, and the featured speaker is Carol Browner, director of the Office of Energy and Climate Change Policy under President Obama and the administrator of the Environmental Protection Agency during the Clinton administration. The meeting is a success, with animated discussion following Browner’s address.

International engineering, construction, and project-management company Bechtel, which is headquartered in Reston, Va., opened its newest office, the Engineering Execution Center, in Knoxville, Tenn. The office—the second Bechtel has opened stateside in the last few months—will provide engineering support for the company’s numerous mission-based projects, and it is the second new U.S. office opened by Bechtel in the past few months—the other being in Chandler, Arizona.

A couple of years ago, my wife and I were looking to purchase a new car. But just as we made that decision, major pricing inflation and supply constraints became an issue. So, we decided to wait. We also knew that we would need new tires before we could sell our current vehicle. Instead of buying the best quality (and expensive) tires, we got the much cheaper ones, knowing we would only use them for a brief period. Why invest in an asset that won’t be serving its purpose for you that much longer, right?

The Nuclear Regulatory Commission last week issued a preliminary “yellow” finding to Dominion Energy for failing to resolve a two-decade-long problem with cracks in the piping of the V. C. Summer plant’s emergency diesel generator (EDG) fuel oil system.

The Nuclear Regulatory Commission will hold its 2023 Workshop on Advanced Manufacturing Technologies for Nuclear Applications on October 24–26 as a hybrid meeting.

The North Carolina General Assembly has overridden Gov. Roy Cooper’s October 2 veto of S.B. 678—a measure aimed at incentivizing the development of nuclear power facilities in the state.

Researchers at Idaho National Laboratory have a new experimental tool to study nuclear fuel under simulated loss of coolant accident (LOCA) conditions in INL’s Transient Reactor Test (TREAT) Facility. A specialized experiment holder called a TWIST capsule holds a fuel sample surrounded by water, which can rapidly drain away during testing, simulating loss of coolant in a light water reactor environment.

I have jumped on the fusion power bandwagon! Power from fusion is going to happen. When I look at it, there are several factors that reinforce this. Technology has advanced and moved from basic science/research to engineering solutions. Several breakthroughs in supportive technologies have made fusion power plants a possibility. Finally—and most importantly—the private sector is heavily involved and investing to help move engineering solutions forward. This has resulted in a few dozen fusion companies developing different technologies with the same power generation goals. It is very reminiscent of the development of LW fission reactors in the 1950s and ’60s.

Technology has advanced in regard to materials and especially high-temperature superconducting magnets, high-energy lasers, and computer modeling. These improvements have allowed machines to become smaller and achieve the density, temperature, and time needed for fusion to occur.

The International Atomic Energy Agency has released the 2023 edition of its annual look at nuclear’s prospects in the coming decades—Energy, Electricity and Nuclear Power Estimates for the Period up to 2050—revising its global growth projections upward for a third consecutive year.

Following the February 2021 radiation release at the National Institute of Standards and Technology (NIST) resulting from a fuel failure in the 20-MWt NIST Center for Neutron Research (NCNR) research reactor, NIST investigated the root cause of the incident and developed corrective actions. The Nuclear Regulatory Commission’s probe of the incident found apparent violations and resulted in a confirmatory order issued in August 2022.

Do you remember the days when nuclear was a contractor’s dream? When craftworkers could work outages every fall and spring at a high wage and make enough to take summers off? When companies had to turn down craftworkers looking for outage work because there were more people than positions? Well, those days are far behind us. How many of us struggle every year to fill our outage billets for pipefitters, boilermakers, and electricians? How many of us see return rates of less than 50 percent for some sites?

Our own worst enemy

Industrial growth and demand in the United States have skyrocketed over the past 10 years in no small part due to our ability to provide reliable and low-cost power. The Tennessee Valley region’s population is growing at three times the national average. Nashville is growing at the rate of one Chattanooga—that is, 180,000 people—every four years.

Standard Power, a provider of infrastructure as a service to advanced data processing companies, has chosen NuScale Power as the technology provider for its plans to develop two small modular reactor–powered facilities in Ohio and Pennsylvania to run nearby data centers, the Portland, Ore.-based SMR developer announced on October 3.

Maintenance can mean no more than keeping the status quo. But plant maintenance programs at U.S. nuclear power plants do that and then some. Even the programs are themselves maintained and improved—and so a long-lived nuclear fleet has improved with time. Read on.

Through its Minority Serving Institution Partnership Program (MSIPP) and Tribal Education Partnership Program (TEPP), the Department of Energy’s National Nuclear Security Administration has awarded five grants totaling $2.5 million to minority-serving institutions (MSIs) and tribal colleges and universities (TCUs).

Georgia Power, primary owner of the Vogtle nuclear plant, announced last Friday that it will pay $413 million to settle a lawsuit brought against it last year by plant co-owner Oglethorpe Power Corporation.

Here we go again: Another “workaround” on U.S. nuclear waste policy just got shot down in a federal courtroom. On August 25, the 5th U.S. Circuit Court of Appeals found that the Nuclear Regulatory Commission lacked the authority to grant a license to Interim Storage Partners LLC (read: Waste Control Specialists) to accept and store up to 5,000 tons of used nuclear fuel at its proposed facility in Andrews County, Texas. Writing for the court, U.S. circuit judge James Ho found that “the Nuclear Waste Policy Act (NWPA) creates a comprehensive statutory scheme for addressing spent nuclear fuel accumulation. The scheme prioritizes construction of the permanent repository and limits temporary storage to private, at-the-reactor storage or at federal sites. It plainly contemplates that, until there’s a permanent repository, spent nuclear fuel is to be stored onsite at-the-reactor or in a federal facility.”

This decision is not necessarily a knockout blow. The court’s reading of the law is, well, novel. Other appeals courts have recognized the NRC’s authority to license away-from-reactor storage, and the Supreme Court is likely to weigh in. But given the current high court’s proclivities on “textualism” and the Chevron doctrine, we shouldn’t consider it a slam dunk.
