Top line: A full nuclear day: X-energy, Alleima and Doosan Enerbility booked the first steam-generator component order for X-energy's high-temperature SMRs, the UK's MAST Upgrade fusion machine took its 12-tonne heating upgrade into position, and Kazakhstan's president set a 100-year uranium reserve aim. San'ao unit 2 in China finished fuel loading.

X-energy books its first steam-generator component order with Alleima and Doosan

What happened: X-energy, Swedish specialty steelmaker Alleima and South Korea's Doosan Enerbility executed a first order for nuclear-industrial steam generator components. Alleima, which calls it its first tube order for next-generation helium-cooled small modular reactors, received the order through Doosan Enerbility; the companies frame the partnership as securing safety-significant, long-lead components for X-energy's high-temperature reactor line.
What's genuinely new: A first purchase order — not an intent-stage memorandum — placing long-lead manufacturing with two named suppliers before any plant is built. Doosan Enerbility is the same Korean heavy manufacturer that signed on in late October to make reactor-module hardware for NuScale, so its SMR supplier role now spans two US developers.
Watch: Which plant deployments the components are destined for, order volumes and delivery schedule, and whether further long-lead orders follow for the Xe-100 line.
UK's MAST Upgrade fusion machine gets its 12-tonne heating upgrade
What happened: Engineers at Britain's MAST Upgrade fusion machine in Oxfordshire moved a 12-tonne double beam box into position. The heating component is set to double the machine's plasma conditions, to 60 million degrees Celsius (108 million °F).
What's genuinely new: A concrete hardware step in the UK's fusion programme: the beam box is installed, turning a planned capability upgrade into physical reality ahead of heated-plasma operations.
Watch: First heated-plasma results against the doubling claim, the machine's experimental schedule, and how UKAEA's upgrade campaign feeds the UK's broader fusion ambitions.

Kazakhstan aims for a 100-year uranium reserve
What happened: President Kassym-Jomart Tokayev said Kazakhstan aims to develop its strategic uranium reserve to meet the needs of its planned nuclear power plants for more than 100 years.
What's genuinely new: A head-of-state statement tying the country's uranium position to a domestic reactor programme — supply planning measured in a century rather than years. No reserve size, funding or timeline appears in the article, so the aim is statement-grade for now.
Watch: Reserve sizing and any enabling legislation, the planned reactor programme it is meant to supply, and how the claim lands with uranium buyers.

Second San'ao reactor loaded with fuel ahead of startup
What happened: Loading of fuel assemblies into the core of unit 2 at the San'ao nuclear power plant in China's Zhejiang province is complete, ahead of the unit's startup. It is the second of six HPR1000 (Hualong One) reactors planned at the site.
What's genuinely new: A fleet-buildout milestone for China's domestic Hualong One line — the site's second unit moving from construction into the fuel-loading and commissioning phase.
Watch: First criticality and grid connection for unit 2, and construction progress on the site's remaining four units.

Brief
- In a commentary for ANS, the author argues the nuclear industry is primed for growth not seen since the 1970s — with utilities weighing new builds and capacity expansions — but that the same growth poses a talent problem few organizations have planned for, and points to talent development as the differentiator. It carries no new program, hiring or survey data.
- Wedbush launched coverage of the listed small-reactor cohort: Seeking Alpha reports NuScale Power rated Underperform with a $5 price target while Oklo, X-Energy and NANO Nuclear got Outperform ratings; TIKR via Yahoo Finance notes X-energy fell 23% over the past month as investors sold small-reactor stocks, with Wedbush seeing 54% upside from here. Analyst opinion, no company action.
