The Strategic Selection of Five PartnersThe US Department of Energy has officially selected five companies to enter advanced discussions regarding the utilization of surplus Cold War-era plutonium as fuel for nuclear reactors.Oklo and newcleo are leading the initiative.Other partners include Exodys Energy, SHINE Technologies, Standard Nuclear, and Flibe Energy.Financial and Material MetricsThe announcement comes with significant market movement and material volume implications.Oklo saw its stock price surge by over 5.5 percent to $69.51 per share.The program targets approximately 20 metric tonnes of weapons-usable plutonium.The material has a half-life of 24,000 years and is currently held at guarded facilities in South Carolina, Texas, and New Mexico.Policy Shifts and Geopolitical ImplicationsThis move represents a major pivot in nuclear waste management and defense posture.The Trump administration halted a previous disposal program to provide this material for advanced reactors.Senator Edward Markey and others raised concerns, noting the material could produce roughly 2,000 nuclear bombs, citing proliferation risks.US Energy Secretary Chris Wright, a former Oklo board member, played a key role in facilitating this transition.The Path Forward for Nuclear LiabilityIndustry leaders view this as a critical step in modernizing the energy grid.Oklo cofounder and CEO Jacob DeWitte emphasized that this creates a pathway to use existing surplus material as bridge fuel, while Stefano Buono of newcleo highlighted the reduction of US nuclear liabilities. The program aims to help companies secure private funding by offering a solution to the disposal problem.

The Familiar FinalYou could be forgiven for having a sense of deja vu before a fourth Champions League final between the Spanish champions, Barcelona, and French champions, Lyonnes, on Saturday evening.The three-time champions and eight-time champions played each other in the final of Europe's premier competition three times in six years between 2019 and 2024, with Lyonnes earning a 4-1 win over the Catalan giants in 2019 and a 3-1 win in 2022 before Barcelona delivered a 2-0 defeat of the French side in 2024.However, predicting the outcome could not be harder and Barcelona's talismanic No 11, Alexia Putellas, said there is little that can be discerned from those previous meetings. "We can't compare seasons and we can't compare finals," said the two-time Ballon d'Or winner. "Our squad has evolved a lot, so previous finals don't have an influence on the final we are playing tomorrow."The Tactical Chess MatchA lot has changed. Most notably, Lyonnes are now managed by Jonatan Giráldez, who was a coach at Barcelona as they claimed their maiden UWCL title and at the helm for their second and third. Few managers are better equipped to return Lyonnes to the top of European football after a three-year hiatus than the man who understands the way Barça work and exactly how they ended the domination of the French side.As a result, the tactical approach of those on the sidelines is perhaps the most interesting piece of the puzzle in Oslo's Ullevaal Stadion.Giráldez said of Barça's development since he left: "They have some different players but their identity remains the same; this will to dominate and apply pressure. Not thinking about the result as much as about the show and the performance, that's their identity. I feel privileged to face Barcelona as I'm grateful for the experience I had there and I wish them the best – except when we have to win!"Master and ApprenticeOne of Giráldez's two assistants, Pere Romeu, replaced him when he departed for Washington Spirit in June 2024. "We are the two teams that have done the most in this competition to reach the final in recent years," said Romeu. "Tomorrow is going to be a very demanding match. Tomorrow is going to be a match with a lot of quality from both teams. Tomorrow is going to be a match that, as in all finals, is going to be decided by small details. We are going to try to take care of and control it to the maximum."The 32-year-old Barcelona manager won a domestic treble in his first season in charge, but fell short in the Champions League final last season as Arsenal delivered a shock defeat."I see a team that is more mature than last season," said Romeu. "I see a team with greater capacity to change things during the game than last season and I think we have reached a good point."Putellas described Romeu as a "complete coach", before the showdown on Saturday. "We've been working together for several seasons now and he has always tried to help me evolve as a player, which I'm very grateful for," she said. "He's the most complete coach. This season I've tried to do the best I possibly can without forgetting my own qualities in order to help the team."Romeu is relishing the master-apprentice battle in such a significant game. "I, as a coach, am super-excited to be able to face this match against a former coach of the club in Jonatan," he said. "I'm sure we'll both do everything we can to keep our teams' identities and keep doing the best we can to win."Dominate DomesticallyBarcelona secured another domestic treble on Saturday with a 3-1 Copa de la Reina final win over Atlético Madrid in their final game before travelling to Norway. Meanwhile, Lyonnes are one game away from their own domestic treble, having dispatched Nantes with an emphatic 8-0 win in the semi-final of the Premiere Ligue play-offs, with the final between the holders and Paris FC, taking place next Friday.The Lyonnes midfielder Lily Yohannes told Uefa that the club "just have so much hunger in us," after their three-year European dry spell. "We have so much fight. No matter what happens, we stick together, we rise above the challenges, and we just have such a winning mentality in the group."The 35-year-old centre-back Wendie Renard, who has been involved in each of the club's record eight Champions League wins, similarly spoke about a togetherness and desire in the team after a disappointing European run last season."If I had to sum up our journey this season: dedication," she told Uefa. "A Champions League campaign never comes easy, from one game to another. We've also had doubts and fears at times, but the squad has remained strong, and we've kept focusing on work and humility and performed well together."The Midfield BattleThe midfield battle will be key, with the impact of Melchie Dumornay, who was the difference maker in their semi-final fightback against Arsenal, critical for Lyonnes and Barcelona unsure of the readiness of the three-time Ballon d'Or winner Aitana Bonmatí, who is "feeling better every day", according to Romeu, but has not played 90 minutes for the team since November and only played 18 minutes of the Copa de la Reina final.Contrasting StylesThe Champions League final will ultimately be a contest between two different ways of playing, Barcelona's slick tiki-taka football and the more aggressive way Lyonnes play. Both cannot dominate possession in this game, one will have to cede it and find a different way to win. That is what makes it an enthralling fixture.
