OPAL 2024 shutdown: update on supply

September 2023

Since we last shared an update regarding the planned shutdown of OPAL in 2024, we’ve been working hard to secure supply options for the nuclear medicine community. 

While this work is still ongoing, we have provided an update below on what we anticipate our supply options will be throughout the planned shutdown. 

Current planned shutdown dates are Monday 18 March 2024 to Friday 5 July 2024, any changes in these dates will be communicated with our stakeholders.

Nuclear Medicine Processing and Distribution Facility maintenance

  • For a period of the shutdown (approximately 10 weeks) we will also conduct maintenance on our Nuclear Medicine Processing and Distribution Facility. The current planned dates for this are Monday 18 March 2024 to Friday 24 May 2024.
  • Conducting maintenance on two of our key facilities that enable nuclear medicine supply simultaneously will help support reliable supply for Australian patients into the future.
  • This maintenance will replace the regular scheduled shutdown of our Nuclear Medicine Processing and Distribution Facility in 2024, which usually occurs in September or October each year.

Product supply

  • ANSTO has been working productively with alternative suppliers to source supply for the domestic market during this period.
  • We have broadened our supply networks by establishing new supply arrangements with international suppliers.
  • These supply arrangements, while always subject to the usual risks of disruptions that can occur in nuclear medicine production, will enable ANSTO to provide some supply of critical nuclear medicine products during the shutdown period.
  • Our focus has been on securing alternative supply for Tc-99m generators, I-131 finished products and Lu-177. 
  • We’ve been working to minimise disruption wherever possible; however, where ANSTO imports product, we are subject to our suppliers’ product availability and logistics.
  • Products that are currently being imported and distributed like Cold Kits (MAA, DTPA and MDP), Iodine-123 MIBG, Iodine-131 MIBG and Gallium-68 generators should not be affected by the shutdown.
  • A summary of our nuclear medicine products and their planned availability is below.
  • You will notice that supply of Lu-177, bulk I-131, and Cr-51 is due to recommence later in the month of July 2024; these resupply dates align with current supply scheduling and take into consideration the reactor’s restart schedule.

I-131 Capsules

5 June 2023

ANSTO has identified an appearance defect in a small number of cases following our routine stability testing for Sodium Iodide (I-131) 50-6000MBq Therapy Capsules. This was identified for higher activity capsules only. (300MBq or more for smaller capsules and 3000MBq or more for larger capsules).

While ANSTO continues to investigate and address the issue in the higher activity capsules, in the short term, ANSTO will only supply the capsules at lower activity levels which have demonstrated compliance with all quality and acceptance criteria.

ANSTO will limit the impact of this change by supplying customers who have high-activity requirements with additional capsules to meet higher activity dosage requirements at no additional cost.
