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 Nuclear Energy eXperimental Testing (NEXT) Laboratory at Abilene Christian University in Texas created quite a bit of buzz within the nuclear community in August when it submitted the first application for a new U.S. research reactor in more than 30 years. The construction permit application submitted to the Nuclear Regulatory Commission is for a molten salt research reactor (MSRR)—the first-ever university application for an advanced research reactor. Assuming NRC acceptance of the application, which could happen this year, a formal technical review of the lab’s MSRR plan will then begin, and construction of the MSRR could be completed by 2025. The Abilene campus’s new Science and Engineering Research Center—a 28,000-square-foot multiuse facility for chemistry, physics, and engineering research and education—is expected to be completed by July 2023 and will house the advanced reactor. The final step is to obtain the NRC operating license for the MSRR and commence operation.

While deep geological repositories (DGRs) are the globally preferred and scientifically proven solution to store high-level radioactive waste, societal challenges remain. Given the long time frames associated with DGR development and implementation, and a rise in global interest in nuclear energy to meet urgent climate mitigation targets, building and maintaining human capacity is now even more of a priority.

Unit 2, a 1,028-MWe pressurized water reactor, was shut down in April 2020; Unit 3, a 1,041-MWe PWR, was closed one year later. (Unit 1 was decommissioned in 1974.)

Just days before COP27 and the U.S. midterm elections, the White House announced $1.55 billion in Inflation Reduction Act (IRA) funding for national laboratories and the launch of a Net-Zero Game Changers Initiative based on a new report, U.S. Innovation to Meet 2050 Climate Goals. Out of 37 research and development opportunities identified, fusion energy was selected as one of just five near-term priorities for the new cross-agency initiative. Together, the announcements signal policy and infrastructure support for fusion energy—the biggest chunk of Department of Energy Office of Science (DOE-SC) IRA funding went to ITER, via Oak Ridge National Laboratory—and for advanced nuclear technologies to power the grid and provide process heat to hard-to-decarbonize industrial sectors.

Since at least June of last year—when TerraPower and PacifiCorp announced plans to site the Natrium reactor demonstration project at one of Wyoming’s retiring coal plants—the concept of repurposing those plants to host nuclear reactors has been a popular topic of conversation among the energy cognoscenti.

An agreement between the United States and Mexico on civil nuclear cooperation has entered into force, the U.S. State Department announced last week. While first proposed in 2016 and finalized and signed in 2018, the pact only received approval from the Mexican Senate this March.
A Northrop Grumman Antares rocket, with the Cygnus spacecraft Sally Ride aboard (so named for first American woman to fly in space), launched at 5:32 a.m. EST on November 7, from NASA's Wallops Flight Facility in Virginia. The rocket is captured just after liftoff in this still image from NASA’s live broadcast of the event.
Seeds from the joint laboratories of the International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations (FAO) are onboard a Cygnus spacecraft launched from NASA’s Wallops Flight Facility in Virginia early on November 7. Now orbiting the Earth en route to the International Space Station, the seeds are part of a commercial resupply mission with a payload that includes resources to support more than 250 scientific investigations.
Curie and Meitner (Photos: Wikicommons)
Marie Curie was born in Warsaw in 1867 on this day, 155 years ago. Exactly 11 years later, in 1878, Lise Meitner was born in Vienna. November 7 is also the date when, in 1911, the Swedish Royal Academy of Science decided to award Curie a second Nobel Prize for her 1898 discovery of the elements radium and polonium (coincidentally, her 44th birthday). Curie, who at age 36 had shared the 1903 Nobel Prize in Physics with her husband, Pierre Curie, and Henri Becquerel, later accepted the chemistry prize on December 10, 1911. She remains to this day the only person—man or woman—to receive two Nobel Prizes in two different fields of science. (Linus Pauling was also awarded Nobel Prizes in two categories: chemistry and peace.) On this unofficial day of women in nuclear science, let’s take a moment to acknowledge the fundamental discoveries of both Curie and Meitner.

New Orleans-based Entergy Corporation yesterday announced changes to its senior leadership, including the selection of Kimberly Cook-Nelson as executive vice president and chief nuclear officer, replacing Chris Bakken.
Cook-Nelson, Entergy’s first female CNO, will be based in Jackson, Miss., the company’s nuclear operations headquarters. She joined Entergy in 1996 as a design engineer at the Waterford nuclear plant in Killona, La., rising to general manager of plant operations in 2011. Most recently, she held the position of chief operating officer, nuclear operations. (In addition to the Waterford facility, Entergy owns and operates Arkansas Nuclear One in Russellville, Ark., Grand Gulf in Port Gibson, Miss., and River Bend in St. Francisville, La.)
Participating in the forum were (from left) John Hopkins (NuScale Power), Renaud Crassous (EDF), Daniel Poneman (Centrus Energy), Adriana Cristina Serquis (CNEA), and Boris Schucht (Urenco).
The nuclear industry leaders assembled in Washington, D.C., last week to discuss small modular reactor supply chains agreed that lost generation capacity from the expected retirement of hundreds or thousands of coal power plants over the next decade—a cliff, in one panelist’s words—represents an opportunity that developers of SMRs and advanced reactors are competing to meet.
“I think in total 80 projects are ongoing,” said Boris Schucht, panel moderator and chief executive officer of Urenco Group, as he opened the forum. “Of course not all of them will win, and we will discuss today what is needed so that they can be successful.”
