Technical Experts from the CNSC conducted a Type II Inspection at the facility from April 23rd – 25th, 2019. The CNSC will summarize the results of the inspection in a formal report and provide it to TRIUMF.
|2019-02||On May 28, 2019 TRIUMF released gaseous krypton at a level 2000 times below the regulatory limit during routine medical isotope production. The event was reported to the regulatory authority. TRIUMF is investigating and will take appropriate action to address the matter.|
|2019-03||On June 14, 2019 technical experts from PLC Fire Safety Solutions inspected TRIUMF’s Facility Fire Hazard Assessment and Fire Protection Systems. Their report will be shared with TRIUMF and CNSC and used to strengthen fire safety across our site.|
|2019-04||On June 18, 2019 TRIUMF detected a slow release of xenon gas from a |
|2019-05||On Aug. 27 and Aug. 28, during routine medical isotope production on a rubidium target, gaseous krypton was released from TRIUMF at a level less than 1/1000 of the regulatory limit. The event was reported to the regulatory authority. As a result of this release, TRIUMF has voluntarily stopped irradiation of rubidium targets for medical isotope production until the root cause of the issue can be identified and appropriately addressed.|
As part of a scheduled safety exercise, there will be an evacuation drill involving all on-site TRIUMF staff and visitors on the morning of September 10, 2019.
On the week of September 23rd, the Canadian Nuclear Safety Commission will be on site to sample collect samples of air, vegetation and soil around the TRIUMF site as part of the Commission’s Independent Environmental Monitoring Program (IEMP). This work is routine and not in response to any particular event or concern with respect to TRIUMF’s operations. Results from the last round of IEMP sampling at TRIUMF can be found here: http://www.nuclearsafety.gc.ca/eng/resources/maps-of-nuclear-facilities/iemp/triumf.cfm
Two small releases of radioactivity occurred in October during medical isotope production. Their combined impact to a member of the general public corresponded to less than 1/15,000 of the regulatory limit, or 1/5,000 of the dose received during the course of a flight from Vancouver to Toronto. TRIUMF investigated the incidents and implemented process improvements to address their root causes and prevent future releases of this type.
On Dec 10th – 13th, 2019, technical experts from the Canadian Nuclear Safety Commission conducted a routine inspection of TRIUMF pursuant to the facility’s operating license. The inspection focused on the operational performance of TRIUMF programs and facilities.
A shielded container containing material used for medical isotope production was damaged by the freight carrier while in transit from TRIUMF. No radiation was released. A new container was procured and the package was conveyed to the intended destination. There was no hazard to personnel or the public.
