Europe’s first EPR, Unit 3 at Finland’s Olkiluoto nuclear power plant, was connected to the nation’s grid on March 12, Teollisuuden Voima Oyj (TVO), the facility’s owner and operator, has announced.
Olkiluoto-3 is also the first new Finnish reactor in four decades, and one of only three new reactors in Europe in the past 15 years. (Romania’s Cernavoda-2 began supplying electricity to the grid in August 2007, and Belarus’s Belarusian-1 in November 2020.)

With three commercial teams under contract to produce reactor designs for nuclear thermal propulsion rockets that would use solid high-assay low-enriched uranium fuel to heat hydrogen propellant, NASA’s investment in nuclear thermal propulsion (NTP) has increased in recent years. But just as there is more than one way to fuel a terrestrial reactor, other fuels are under consideration for future NTP rocket engines.
At the press conference, Grossi explained that the IAEA has stopped receiving safeguards information from certain monitoring systems installed at Ukrainian nuclear facilities, as indicated by the red dots.
IAEA director general Rafael Mariano Grossi traveled to Antalya, Turkey, on March 10 to meet with Ukrainian foreign minister Dmytro Kuleba and Russian foreign minister Sergei Lavrov to discuss the safety and security of Ukraine's nuclear facilities. After returning to Vienna, Grossi held a press conference at which he said that a “common denominator” had emerged from the discussions and that both sides agree that something needs to be done. “They are both ready to work and to engage with the IAEA,” he said. “So this is a very important building block.”

The United Kingdom’s Department of Business, Energy and Industrial Strategy (BEIS) has asked regulators—including the U.K. Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales—to begin a generic design assessment (GDA) of Rolls-Royce SMR’s 470-MWe small modular reactor design.

Unit 3 at Pakistan’s Karachi nuclear power plant has been connected to the national grid, China National Nuclear Corporation (CNNC) announced on March 4, making it the second Hualong One reactor outside of China to have reached the last major step prior to commercial operation. (The distinction of being the first belongs to Unit 3’s twin, Karachi-2, which was connected to the grid in March 2021 and entered commercial operation in May.)
Karachi-3 had achieved criticality on February 21 after completing hot functional testing and entering the fuel loading stage last November.

Ultra Safe Nuclear Corporation (USNC), an advanced reactor and reactor fuel developer, announced last week that it plans to begin operations this summer at its Pilot Fuel Manufacturing (PFM) facility in Oak Ridge, Tenn., pending the receipt of the requisite state and local permits. The facility is located in the East Tennessee Technology Park, site of the Manhattan Project’s K-25 gaseous diffusion plant. USNC purchased an 8.7-acre site—which included a preexisting industrial building—from Heritage Center LLC in 2021.

Constellation Energy’s Dresden nuclear power plant in Illinois is helping University of Chicago researchers to detect neutrinos in an effort to advance knowledge of the fundamental laws governing particle and nuclear interactions. The researchers are taking advantage of the large number of neutrinos generated by Dresden’s boiling water reactors to conduct experiments, using what UChicago calls the world’s smallest neutrino detector to track and record the ghostlike particles.
