Power & Operations

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.

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.

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.

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.

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.

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.

Holtec International has taken another step on the arduous stairway to Palisades resurrection, announcing last Friday that it has filed with the Nuclear Regulatory Commission to “formally begin the process of seeking federal reauthorization of power operations” at the Covert Township, Mich., facility.

A digital twin is a virtual replica of a real system or physical asset. It is a trusted data source containing vital information about an asset, which could include dimensions, relevant manufacturer information, operations history, and maintenance records. To realize the maximal benefit from a digital twin at a nuclear power plant, for example, it must evolve as the facility is designed, constructed, and operated. Some general attributes and the resulting benefits of a digital twin follow:

Early last month, Newswire reported that a pronuclear bill under consideration in North Carolina looked likely to make its way to Gov. Roy Cooper’s desk, but less likely to be signed into law. We were right on both counts.

The U.K. government has chosen six companies to participate in the next stage of its small modular reactor competition: EDF, GE Hitachi Nuclear Energy, Holtec Britain Limited, NuScale Power, Rolls-Royce SMR (the only real home team), and Westinghouse Electric Company UK Limited. According to the government’s October 2 announcement, the advanced technologies offered by these firms are “the most able to deliver operational SMRs by the mid-2030s.”

Technology, Experience, and Efficiency in Fire Protection & Physical Security

The Texas Advanced Nuclear Reactor Working Group—formed recently by the Public Utility Commission of Texas (PUCT) at the direction of Gov. Greg Abbott—hosted its first public meeting last Thursday to discuss the group’s organizational structure and outline a plan to turn Texas into a national leader in the use of advanced nuclear energy.

Canada will provide C$3 billion (about $2.2 billion) in export financing to Romania’s nuclear operator, Nuclearelectrica, in support of Canadian participation in the project to complete Units 3 and 4 at the Cernavoda nuclear plant, Canadian minister of energy Jonathan Wilkinson announced last week.

Just one week after inking a consortium agreement to partner on the design and construction of Poland’s first nuclear power plant, Westinghouse Electric Company and Bechtel joined state-owned Polish utility Polskie Elektrownie Jądrowe (PEJ) in Warsaw on Wednesday for the signing of the project’s engineering services contract.

Poland’s General Directorate for Environmental Protection (GDOŚ) has given its imprimatur to the Central European nation’s plan to build and operate its first nuclear power facility, state-owned utility Polskie Elektrownie Jądrowe announced last Friday.

PEJ, which submitted its environmental impact report for the proposed project to GDOŚ in March 2022, called the decision “a key permit obtained in the investment process, because subsequent administrative approvals, including the decision to determine the location of the investment and the building permit, must comply with the arrangements and conditions contained in the decision on environmental conditions.”

Canada’s Alberta province is investing C$7 million (about $5.2 million) to help Cenovus Energy study how small modular reactors could be used in northern Alberta to decarbonize oil sands production and what additional information might be needed to pursue their regulatory approval.

Westinghouse Electric Company and engineering, construction, and project management firm Bechtel on September 20 announced the signing of a consortium agreement to partner on the design and construction of Poland’s first nuclear power plant.

The U.S. Embassy in Ghana last week announced $1.75 million to support establishing the West African nation as a small modular reactor regional training hub and center of excellence for the sub-Saharan African region.

The project is backed by the Foundational Infrastructure for Responsible Use of Small Modular Reactor Technology (FIRST) capacity-building program, in which Ghana has participated since 2022.
