Mike Kramer has a background in finance, not engineering, but a combined 20 years at Exelon and Constellation and a key role in the deals that have Meta and Microsoft buying power from Constellation’s Clinton and Crane sites have made him something of a nuclear expert.

Kramer spoke with Nuclear News staff writer Susan Gallier in late August, just after a visit to Clinton in central Illinois to celebrate a power purchase agreement (PPA) with Meta that closed in June. As Constellation’s vice president for data economy strategy, Kramer was part of the deal-making—not just the celebration.

It has been about three months since the Department of Energy named 10 companies for its new Reactor Pilot Program, which set an ambitious goal of having three reactors achieve criticality by July 4, 2026.

Hawthorne, Calif.–based reactor start-up Valar Atomics recently announced that it has raised $130 million in its Series A funding round, led by venture capital groups Snowpoint, Day One, and Dream.

Canada’s Fusion Fuel Cycles Inc. (FFC), a joint venture between Canadian Nuclear Laboratories and Japan’s Kyoto Fusioneering, announced that it has officially entered the construction phase of its flagship project, the Unique Integrated Testing Facility (UNITY-2), at CNL’s Chalk River Laboratories in Ontario.

The Department of Energy’s Idaho Operations Office has approved the Nuclear Safety Design Agreement (NSDA) for Oklo Inc.’s Aurora Fuel Fabrication Facility (A3F) at Idaho National Laboratory. The A3F is being built to fabricate fuel assemblies for Oklo’s Aurora Powerhouse, a liquid metal–cooled, metal-fueled fast reactor with a maximum power of 75 MWe.

Advanced reactor and fuel developer X-energy has officially begun confirmatory irradiation testing at Idaho National Laboratory on its TRISO-X fuel. The testing, which is taking place over the course of the next 13 months, will evaluate the fuel across a variety of operating scenarios and—if all goes according to plan—will be instrumental in qualifying it for commercial use.

At the American Nuclear Society’s Winter Conference & Expo, leaders of advanced reactor start-ups Radiant Industries, Oklo, and Valar Atomics praised the Department of Energy’s Reactor Pilot Program, in which the companies are participating. The program aims to get at least three reactors on line by July 4, 2026.

BWX Technologies and Purdue University have signed a memorandum of understanding to collaborate on research focused on next-generation nuclear technologies, including small modular reactors and microreactors.

In a letter to the Office of the U.S. Trade Representative, the Source Security Working Group (SSWG) is urging the U.S. government to withhold from imposing tariffs on Canadian-orgin cobalt-60 and to preserve the duty-free treatment of the radioisotope.

During speeches at the American Nuclear Society’s Winter Conference & Expo, happening this week in Washington, D.C., Energy Secretary Chris Wright and Nuclear Regulatory Commission Chair David Wright both promised that the Trump administration will speed up nuclear reviews so the U.S. can maintain leadership in nuclear energy.

The DOE’s Wright took a stab at the NRC’s traditionally slow bureaucratic processes in approving primarily large light water reactors in the past, saying that the agency needs to speed up to meet the greater demand for new small modular reactors.
