Researchers at Idaho National Laboratory in early 2023 manufactured commercial-grade high-assay low-enriched uranium (HALEU) fuel pellets to the specifications of a General Electric accident tolerant fuel design, INL announced November 21. A team working at INL’s Experimental Fuels Facility at the Material and Fuels Complex fabricated about two dozen uranium dioxide pellets using HALEU enriched up to 15 percent U-235.

Investment opportunities for nuclear energy

Nuclear energy stocks “have become far more compelling to many investors in recent years,” and “there are good reasons to support this carbon-free source of energy,” according to investment entrepreneur and financial lecturer Jason Hall. In an article recently published by The Motley Fool, Hall discusses the opportunities and risks of investing in nuclear energy companies and offers his perspective on three top nuclear energy stocks.

Nuclear basics and new innovations: Hall started at the beginning, describing the most basic aspects of nuclear energy: the production of heat through fission, the generation of electricity via turbines, and the mining and enrichment of uranium for fuel. He noted that there “are only a small handful of companies with the expertise and financial strength to deal with nuclear reactors, and almost all are either private, state-owned, or the subsidiary operation of a large industrial conglomerate.”

NuScale Power announced yesterday that it has joined the Romanian Atomic Forum, aka Romatom, as a supporting member “to champion the association’s nuclear energy goals and further the next generation of advanced nuclear technology experts, technologists, and operators in Romania.” The move further deepens the American small modular reactor company’s commitment to the deployment of a VOYGR SMR plant in the Central European state.

Promising nuclear technologies receive $22.1 million from DOE

May 10, 2023, 12:01PMNuclear News

The Department of Energy yesterday announced the awarding of $22.1 million to 10 industry-led nuclear projects, including two aimed at expanding clean hydrogen production and one at advancing a microreactor design. Other projects selected for funding are focused on addressing nuclear regulatory hurdles, improving existing reactor operation, and facilitating new advanced reactor developments.

Abstracts for all 10 projects can be found here.

NRC to start review of NuScale uprated SMR design

March 28, 2023, 9:31AMNuclear News

The Nuclear Regulatory Commission recently announced that it will begin reviewing most of the standard design approval (SDA) application for NuScale Power’s uprated small modular reactor technology, with the remainder of the review on hold until the company provides additional details on a key safety topic.

The Tennessee Valley Authority took Browns Ferry-2 off line February 17 for a refueling and maintenance outage, following a nearly two-year, breaker-to-breaker run—the first in the Alabama nuclear plant’s history.

According to the utility, the unit established a new record for itself with 665 days of continuous operation, producing more than 20 billion kilowatt-hours of electricity.

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.

Mexico’s Laguna Verde-2 receives 30-year life extension

Unit 2 at Mexico’s Laguna Verde nuclear plant has been given the go-ahead to operate into the 2050s, plant owner and operator Comisión Federal de Electricidad (CFE) announced last week.

Mexico’s secretary of energy, Norma Rocío Nahle García, approved a 30-year extension to the unit’s operating license on August 25, following a review by the country’s National Commission for Nuclear Safety and Safeguards. The reactor, one of two at the plant, is now authorized to run until April 10, 2055.

NRC to issue rule certifying NuScale design

The Nuclear Regulatory Commission has directed its staff to issue a final rule certifying NuScale Power’s small modular reactor design for use in the United States, the agency announced last Friday.

Certification of the Portland, Ore.–based SMR developer’s design will become effective 30 days after publication of the rule in the Federal Register. The design will be incorporated as Appendix G to 10 CFR Part 52, Licenses, Certifications, and Approvals for Nuclear Power Plants.

The origins of The Reactor Safety Study

In March 1972, Stephen Hanauer, a technical advisor with the Atomic Energy Commission, met with Norman Rasmussen, a nuclear engineering professor at the Massachusetts Institute of Technology. The AEC had recruited Rasmussen to develop a report, The Reactor Safety Study (WASH-1400), to estimate the probabilities and consequences of a major nuclear power plant accident. With thousands of safety components in a modern reactor, the task was mind-boggling. Rasmussen proposed a novel approach based on more powerful computers, “fault tree” methodology, and an expanding body of operational data. By calculating and aggregating probabilities for innumerable failure chains of components, he believed he could develop a meaningful estimate of overall accident risk. WASH-1400 would be a first-of-its-kind probabilistic risk assessment (PRA).

Framatome declares ATF test at Vogtle a success

February 8, 2021, 7:00AMNuclear News

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.”

Fuel innovation: Powering nuclear modernization

January 18, 2021, 9:35AMNuclear NewsBen Holtzman

Today’s U.S. commercial nuclear power plants are fueled with uranium dioxide pressed into cylindrical ceramic pellets—and have been for decades. These pellets are stacked inside long fuel rods made of a zirconium alloy cladding. Innovation in nuclear fuel, however, can improve safety, reduce operating costs, and further enable the development of a new generation of non-light-water reactors.
