Maintenance and supply

11 October

Significant progress has been made to date on scheduled maintenance of ANSTO’s Nuclear Medicine Processing and Distribution Facility.

COVID-19 working conditions impacted some milestones; as a result, we will supply Technelite generators for an additional week, transitioning to Gentech generators from 25 October.

Gentech Generators

  • Our operational teams will continue working on A/B rosters for the foreseeable future to mitigate any risk associated with COVID-19.
  • Your Gentech generator delivery schedule will resume to your pre-maintenance shutdown profile, individual customer schedules will be advised next week.

I-131 capsules and solutions

  • I-131 capsules and solutions calibrated Monday 25 October will be available for delivery from Tuesday 19 October. There will be no calibration Monday 18 October.
  • Large solutions over 1201 MBq will be available from Thursday 21 October.
  • Order cut-off for I131 capsules and solutions will remain at 1pm the day prior to despatch.

I-123 radiochemical

I-123 radiochemical will be available for delivery and calibration Tuesday 19 October and Tuesday 30 November.  


Lutetium-177 will be available via import supply returning to ANSTO manufactured supply from Monday 25 October, an updated schedule will be sent to Lutetium-177 customers.  

Chromium- 51

Under A/B rosters, November and December Calibration is currently unavailable, we will keep all customers updated with any changes to this.

I-123 radiochemical

COVID-19 transmission within nuclear medicine presents a risk to the security of supply. Any positive case within ANSTO's supply chain will likely see our facilities quarantined for a lengthy time.

To mitigate risk, we continue to operate an altered staffing arrangement, similar to 2020. As a result, the supply of I-123 radiochemical will be available for 19 October only.

We are assessing an additional delivery for 1 December, which we'll confirm by 4 October.ANSTO apologises for these changes, which are a result of the extension to restrictions related to COVID-19. We ask those customers who intend to place orders for I-123 radiochemical to call Customer Service to discuss requirements.
