Looking back at 2022—January through March

January 3, 2023, 3:00PMNuclear News

Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from January through March 2022.

Stay tuned this week for the top stories from the rest of the past year.

But first, click here for some of ANS’s activities for 2022.

The Steam Generating Team (SGT)—a joint venture of Framatome and United Engineers & Constructors Inc.—has completed a project to replace the Unit 2 steam generators at the Watts Bar nuclear plant, Framatome announced last week.

Watts Barr’s owner and operator, the Tennessee Valley Authority, awarded Framatome the contract for the work in early 2020.

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced the three recipients of its fourth and final round of 2022 vouchers on October 10. The vouchers were awarded to Curio Solutions, which is developing a spent fuel recycling process, and to two companies that are separately investigating advanced reactor siting—Elementl Power and the Tennessee Valley Authority (TVA). The funds for each award will go directly to Oak Ridge National Laboratory.

The Nuclear Regulatory Commission issued a draft environmental impact statement (EIS) recently on Kairos Power’s application for a permit to construct Hermes, a 35-MW nonpower version of the company’s fluoride salt–cooled reactor design (KP-FHR), at the East Tennessee Technology Park in Oak Ridge, Tenn.

The Tennessee Valley Authority and GE Hitachi Nuclear Energy (GEH) have signed an agreement to support planning and preliminary licensing for the potential deployment of a BWRX-300 small modular reactor at the Clinch River site near Oak Ridge, Tenn., the utility’s president and chief executive officer, Jeff Lyash, announced last week.

An evolution of GEH’s 1,520-MWe Generation III+ ESBWR design, the BWRX-300 is a 300-MWe water-cooled, natural-circulation SMR with passive safety systems.

As part of its strategy to achieve net-zero status by 2050, the Tennessee Valley Authority yesterday issued a request for proposals for supplying up to 5 GW of carbon-free energy that must be operational before 2029.

NN Asks: How do a meteorologist’s forecasts shape nuclear utility planning?

July 6, 2022, 12:06PMNuclear News


Jennifer Call, Meteorologist:
When you think of a meteorologist, what is the first thing that comes to mind? For many it is your local TV meteorologist delivering a weathercast for the 5 o’clock news, or perhaps a meteorologist at the National Weather Service issuing severe storm warnings. But did you know that utilities rely on meteorologists for daily support?

U.S. nuclear capacity factors: A smaller fleet invested in the future

May 13, 2022, 2:59PMNuclear NewsSusan Gallier

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.

Kairos Power forms advisory consortium with four nuclear utility partners

April 20, 2022, 12:00PMNuclear News

Kairos Power announced today that it has assembled an advanced nuclear development advisory consortium with four North American nuclear operators—Bruce Power, Constellation, Southern Company, and the Tennessee Valley Authority—dubbed Kairos Power Operations, Manufacturing and Development Alliance (Kairos Power-OMADA).

Clinch River in the Spotlight

Last week’s announcement from the Tennessee Valley Authority about its “New Nuclear Program,” which outlines the potential development of the Clinch River site near Oak Ridge National Laboratory in Eastern Tennessee, is the catalyst for this week’s #ThrowbackThursday post. The Clinch River site was originally planned to be the location for the Clinch River Breeder Reactor, a project that, at the time, was meant to be the future of the nuclear industry in the United States.

TVA board approves advanced reactor program; initial focus on Clinch River

The Tennessee Valley Authority’s board of directors has given the go-ahead for a program that will explore the development and potential deployment of small modular reactors as part of the utility’s decarbonization strategy.

Tennessee governor gives nuclear another rhetorical boost

February 3, 2022, 7:22AMNuclear News

Lee

In his annual State of the State Address on January 31, Tennessee Gov. Bill Lee offered more praise for nuclear energy, after lauding it earlier in the month during a tour of the Tennessee Valley Authority’s Watts Bar nuclear plant

“For decades, East Tennessee has been home to some of the best-kept secrets in nuclear energy and American innovation,” Lee told the state’s General Assembly. “Today, many may not realize that Tennessee derives more power from nuclear energy than from any other source. Recently, I visited the TVA’s Watts Bar nuclear facility, the last nuclear facility to be built in America, to see firsthand how nuclear power keeps our grid dependable even when the weather is not. Nuclear power is clean energy that actually works for the private sector.”

Tennessee governor backs nuclear energy and TVA's plans for SMRs

During a tour last week of the Tennessee Valley Authority’s two-unit Watts Bar nuclear power plant in Tennessee, Gov. Bill Lee said, "Nuclear energy is so important not only because it is an important part of TVA's power generation but also because of the value that clean energy via nuclear energy can have for sustainability in this country,” according to an article in the Chattanooga Times Free Press.

Lee added that he would support TVA’s plans if it decided to build small modular reactors.

TVA gives up construction permits for Bellefonte units

September 22, 2021, 7:02AMNuclear News

Nearly 47 years after being issued construction permits for two reactors at the Bellefonte site in northeast Alabama, the Tennessee Valley Authority has decided against renewing them, essentially extinguishing any remaining hope for the project, on which the utility has reportedly spent more than $5 billion.

Woke nuclear?

After decades of relinquishing its value and return on investment as “emission-free” electricity generation, segments of the nuclear industry are pursuing actions in several states to secure emission credits for avoiding greenhouse gas emissions. To harmonize electricity market stability and greenhouse gas emission reduction goals, states such as New York and New Jersey have enacted programs to award zero emission credits (ZECs) to nuclear plants for their emission-free output.

Dearly earned and too long forgone, air emission credits have been the economic birthright of the nuclear industry since the passage of the 1990 Clean Air Act (CAA) amendments, when emission control capability first became a tradable commodity. Yet it took until 2016 for ratepayers and shareholders to receive even a small fraction of this valuable return on investment.

A federal court last week sided with the Tennessee Valley Authority in its legal dispute with Nuclear Development LLC over the proposed sale of the unfinished Bellefonte nuclear power plant. The court, however, also ordered the utility to refund millions to Nuclear Development over the aborted transaction.

In an evaluation report released last week on the Sequoyah nuclear plant’s chemistry/environmental program, the Tennessee Valley Authority’s Office of the Inspector General identified certain risks, both behavioral and operational, that could impact organizational effectiveness. Program behavior was assessed from interviews and field work conducted from September 21 through November 3, 2020, with operations assessed in February of this year.

2020 enforcement cases rise but still below five-year average

June 22, 2021, 9:29AMNuclear News

The Nuclear Regulatory Commission recently released its Enforcement Program Annual Report for calendar year 2020, showing a total of 61 escalated enforcement actions taken last year against licensees, non-licensees, and individuals—an increase of 7 percent from CY 2019, but a number that remains below the five-year (2016–2020) average.
