Fuel form
Uranium metal (Magnox) or uranium dioxide (AGR)
Enrichment
Natural uranium to 2.5–3.5% U-235 no enrichment required
Upstream

This unit runs on natural uranium, so its fuel chain has no enrichment step at all: mine → mill → conversion → fabrication. That is the shortest fuel chain of any commercial reactor type, and it makes the operator independent of the four organisations that control enrichment worldwide.

Fabricator capability is recorded against reactor type and model line, not against named units — utilities do not publish fuel contracts. See the fuel chain.
