HFR Reactor Restart Delayed; Some Disruption to Mo-99 Supply Expected

April 9, 2024

The Nuclear Research and Consultancy Group (NRG) communicated that a deviation had been found in the cooling system of the Petten High Flux Reactor (HFR) in Petten, Netherlands, which delayed the restart of HFR for its next cycle.

The HFR team made good progress with the required technical modification, allowing HFR to restart on April 7.

Nuclear Medicine Europe (NMEU) anticipates some disruptions to Mo-99 supply this week, but I-131 supplies are expected to be stable.
