Researchers at General Atomics (GA) are proposing a breeding blanket made of modular silicon carbide–based components to withstand the intense conditions in a high-power fusion power plant. The GA modular blanket (GAMBL) concept is described in an article published this month in the journal Fusion Engineering and Design, and was introduced by GA in a July 13 press release.

U.K.-based reactor developer Rolls-Royce SMR last week announced a list of six potential sites for its first small modular reactor factory. According to the company's announcement, the factory—the largest and most complex of three such facilities envisioned by the company—will manufacture the SMR vessels.

NuScale Power and Paragon Energy Solutions have signed a patent license agreement that will make NuScale’s Nuclear Regulatory Commission–approved reactor protection system architecture available to the broader nuclear industry, the two companies announced on July 12.
Known as the Highly Integrated Protection System (HIPS) platform, the system was developed by NuScale and Rock Creek Innovations (RCI), a hardware supplier of commercial nuclear protections systems, over six years of collaboration that began in 2010. Paragon, a supplier of safety-related parts and components, acquired RCI in December 2021.
A construction permit was issued for the first of four proposed reactors at Egypt’s El Dabaa site, about 185 miles northwest of Cairo. (Image: Wikipedia)
The Egyptian Nuclear and Radiological Regulation Authority (ENRRA) recently issued the construction permit for the first of four proposed Russian-designed and -supplied reactors at Egypt’s El Dabaa site, located on the Arab nation’s Mediterranean coast, about 185 miles northwest of Cairo.
An application for the permit was submitted by Egypt’s Nuclear Power Plants Authority (NPPA)—the public entity charged with operating the plant—in June of last year.

The Nuclear Regulatory Commission has published its final environmental impact statement (EIS) for Holtec International’s proposed HI-STORE consolidated interim storage facility (CISF) for spent nuclear fuel in southeastern New Mexico. Based on its environmental review, the NRC staff recommends issuing the license, subject to the findings in the staff’s ongoing safety review of the application.

The Department of Energy’s Office of Environmental Management (EM) said it continues to make progress toward the start of operations of the Idaho National Laboratory Site’s Integrated Waste Treatment Unit (IWTU), having completed a final test run of the facility.
Operation of the IWTU, which was constructed to treat approximately 900,000 gallons of radioactive liquid waste, has been delayed a number of times, most recently due to supply chain issues.
TVA's Watt Bar nuclear power plant.
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.
The Waste Isolation Pilot Plant in southeastern New Mexico.
Reston, Va.-based Tularosa Basin Range Services (TBRS), a single-purpose entity under the umbrella of Bechtel National, has been awarded the 10-year, $3 billion management and operating contract for the Waste Isolation Pilot Plant (WIPP) by the Department of Energy’s Office of Environmental Management (EM). Located near Carlsbad, N.M., WIPP is the DOE’s geologic repository for defense-generated transuranic waste.
The new contract replaces the current WIPP M&O contract held by Nuclear Waste Partnership, which expires on September 30. The contract with TBRS was announced on July 11.

Iran has begun enriching uranium to a purity level of 20 percent using advanced IR-6 centrifuges at its Fordow Fuel Enrichment Plant, a pilot facility located underground near the city of Qom. The Atomic Energy Organization of Iran made the public announcement on June 10, although it reported the news to the United Nations’ International Atomic Energy Agency two weeks before, according to NBC News.

Vattenfall has initiated a study to look into the feasibility of building at least two small modular reactors adjacent to its Ringhals nuclear power plant, the Swedish state-owned power company announced recently.
Located on Sweden’s west coast about 37 miles south of Gothenburg, Ringhals holds two operating power reactors: Unit 3, a 1,074-MWe pressurized water reactor; and Unit 4, a 1,130-MWe PWR. The facility is also home to two retired units: Unit 1, a boiling water reactor shut down in December 2020; and Unit 2, a PWR taken off line in December 2019.
