I-131 supply
The state of the reactors and processors that produce the world's Iodine-131, read from their operators, their regulators and the sector's emergency channel. Each line is our own summary of a dated primary document, with the link to the original. Nothing here is a forecast.
Supply status by region
Derived from the reactors and processors documented as suppliers of each region. Amber: a current unplanned or extended outage at a reactor or processor serving it. Red: a shortage notice from an authority or the sector's emergency channel in the last fourteen days. Never on inference.
EuropeNo disruption reported
The ANVS issues an order subject to a penalty payment to NRG PALLAS (operator of the HFR) in a news report dated September 4, 2026.
North AmericaNo news
No news from the sources in the last 60 days.
Latin AmericaNo disruption reported
CNEA · News · Officials from the Secretariat of Nuclear Affairs and the National Atomic Energy Commission presented guidelines for the future operation of the multipurpose reactor as a platform...
Africa and Asia-PacificNo disruption reported
Planned outage at OPAL (Lucas Heights) from September 14 to September 19, 2026, for refuelling and maintenance, according to ANSTO’s cycle schedule; Cycle 176 will remain online starting September 19.
Irradiation reactors
The reactors that irradiate the targets. The status comes from the last availability signal in the last 60 days, and the last signal is the most recent dated document, each with its source.
