Fuel innovation: Powering nuclear modernization

The $111.2 million in financial assistance awarded by the Department of Energy in late 2018 to nuclear fuel developers Framatome, General Electric, and Westinghouse for the development of accident tolerant fuel has yielded some encouraging results.

Framatome reports that the first 18-month fuel cycle test of its GAIA Enhanced Accident Tolerant Fuel (EATF) technology, conducted at Southern Nuclear’s Vogtle-2, has “demonstrated expected results and excellent performance.”

And last month, Westinghouse announced that the topical report on its Advanced Doped Pellet Technology fuel has been accepted for review by the Nuclear Regulatory Commission, calling the decision “a major achievement for the advanced fuel portfolio Westinghouse is developing.”

Amid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.

The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.

A Montana Senate committee last week passed a joint resolution calling for the creation of a legislative panel to study the feasibility of replacing the coal-fired units at the state’s Colstrip power plant with advanced small modular reactors.

Two of Colstrip’s four coal boilers were permanently closed in January 2020, and most energy-sector observers expect the remaining two units to be retired within the next few years, given coal’s declining prospects in states such as Washington, which has passed legislation banning utilities from using coal power after 2025.

The resolution, known as SJ3, also calls on the panel to evaluate current Montana regulations that need revision in order to enable the construction and operation of advanced nuclear reactors. The study would need to be concluded before September 15, 2022.

The Nuclear Regulatory Commission has opened registration for its annual Regulatory Information Conference (RIC), the largest public meeting the agency hosts. Scheduled for March 8–11, the 33rd RIC will be an all-virtual event.

The full conference program and registration information can be accessed from the RIC Web page.

Details: In addition to remarks from the NRC commissioners and the executive director of operations, RIC 2021 will feature two special plenary sessions, including one in recognition of the 10th anniversary of the Fukushima Daiichi accident, and 28 technical sessions covering a wide range of topics, such as advanced reactors, accident tolerant fuel, artificial intelligence, cybersecurity, microreactors, and risk-informed decision making.

ANSI/ASME/ANS RA-S-1.4-2021, “Probabilistic Risk Assessment Standard for Advanced Non-Light Water Reactor Nuclear Power Plants,” has just been issued. Approved by the American National Standards Institute (ANSI) on January 28, 2021, this joint American Society of Mechanical Engineers (ASME)/American Nuclear Society (ANS) standard sets forth requirements for probabilistic risk assessments (PRAs) used to support risk-informed decisions for commercial nuclear power plants and prescribes a method for applying these requirements for specific applications.

ANSI/ANS-RA-S-1.4-2021 and its preview are available in the ANS Standards Store.

The landscape of Exelon Generation’s nuclear business has continued to evolve—even before the complications of a pandemic—but people will always remain the core focus. Our employees and our future employee pipelines are changing almost as fast as technology, which is why the development of the workforce, both present and future, along with the transfer of knowledge across all departments and levels of the organization, must remain adaptable and advance as well.

Westinghouse last week announced via blog post that a topical report on its Advanced Doped Pellet Technology (ADOPT) fuel has been accepted for review by the Nuclear Regulatory Commission, calling the decision a “major achievement for the advanced fuel portfolio Westinghouse is developing as part of our EnCore fuel program.”

The company submitted the report in May of last year, requesting approval by February 2022. According to Westinghouse, a draft safety evaluation from the agency is expected this summer.

The Nuclear Regulatory Commission has opened for public comment the license transfer proceedings for the Palisades nuclear power plant, with the opportunity to request a hearing and petition for leave to intervene. Notice of the open proceedings was published in the February 4 Federal Register. Deadlines are February 24 for requests for a hearing and March 8 for comments.

In December, Entergy Corporation and Holtec International jointly submitted an application to the NRC for approval of the transfer of the licenses for the Palisades nuclear plant–located in Covert, Mich.—to Holtec, following the plant’s permanent shutdown and defueling in the spring of 2022. The application also requests approval of the license transfer of Entergy’s decommissioned Big Rock Point facility near Charlevoix, Mich., where only the independent spent fuel storage installation (ISFSI) remains.

Czech Republic political parties have agreed to exclude China from participating in a tender to build an additional reactor at the Dukovany nuclear plant but have yet to decide whether to allow Russian participation, according to a report last week from Reuters.

Other bidders on the project, estimated to be worth some €6 billion (about $7.2 billion), include Korea Hydro & Nuclear Power of South Korea, EDF of France, and Westinghouse of the United States.

The Nuclear Regulatory Commission has accepted for review NextEra Energy’s subsequent license renewal (SLR) application for its Point Beach reactors, making them the fifth and sixth units currently under consideration for a second 20-year license renewal. (SLR applications for Dominion Energy’s North Anna-1 and -2 and Surry-1 and -2 are also being reviewed, while SLR approval has been granted for Exelon’s Peach Bottom and NextEra’s Turkey Point units.)

NextEra submitted the SLR application in November of last year—the first such application involving a Midwestern nuclear plant. The NRC approved the plant’s initial license renewal in December 2005, allowing Unit 1 to operate through October 5, 2030, and Unit 2 through March 8, 2033.
