Notes
China's sodium-cooled fast reactor demonstration unit. Capacity discrepancy flagged: file 560 MW net vs WNA reactor page 600 MW net (682 gross) vs Wikipedia 642 net — needs PRIS-direct resolution; values frozen. Low-power operation since mid-2023 per fissilematerials.org (HEU/TVEL initial core); grid connection unconfirmed in any source — opacity noted, not asserted.
