Rooppur 1 achieves criticality — Bangladesh's first unit goes self-sustaining
From the Energy digest for 2026-10-12
What happened: The first unit at Bangladesh's Rooppur Nuclear Power Plant achieved criticality — a self-sustaining nuclear reaction — at 15:34 on Sunday, 2026-10-11 (Bangladesh time, ≈5:34 AM US Eastern). World Nuclear News carried the report on 2026-10-12 (~8:47 AM ET).
What's genuinely new: Debut — no storyline in the memory tracks Rooppur. The nearest existing line is "newgen — Rosatom export push: Tanzania (Mkuju River)" (opened 2026-10-11), but that thread covers Rosatom's East-Africa uranium-belt outreach (mining, workforce, possible SMR cooperation), not a South-Asian large-build; Rooppur is the same exporter's construction program reaching its first physical milestone and is logged as its own line rather than folded into the Tanzania thread.
Watch: Follow-on milestones for the unit (grid synchronisation through to commercial operation), and whether Rosatom's export ledger — now spanning Tanzania and Bangladesh on this record — continues adding entries.
