This review of the global Cobalt-60 supply chain is critical in understanding the current state and future prospects of this essential isotope's availability. Cobalt-60, a radioactive isotope used in medical, industrial, and food sterilization applications.

Nordion is at the forefront, expanding Cobalt-60 production capacity to meet growing industry demands. A key initiative is the partnership with Darlington Nuclear Generating Station in Ontario, Canada, which is pivotal in increasing Cobalt-60 production. The station's refurbishment is designed not only to extend its lifespan but also to create its Cobalt-60 production capabilities, ensuring a reliable isotope supply.

Similarly, Westinghouse has been involved in an initiative to augment Cobalt-60 production. Leveraging its extensive experience in nuclear technology, the Westinghouse – Nordion partnership has developed an innovative method to optimize Cobalt-60 output from Pressurized Water Reactors (PWRs) operating in the U.S.. This includes the development of specialized fuel assemblies and reactor core configurations that can maximize Cobalt-60 production without compromising the primary function of electricity generation.

The Pickering Nuclear Generating Station in Ontario is currently in the planning phase of undergoing refurbishments to extend its operational life and potentially boost its Cobalt-60 production capacity. As a significant contributor to the global Cobalt-60 supply, Pickering's enhancements will reinforce its supply chain role.

These efforts, along with ongoing partnerships, signify a collective endeavor to ensure a steady Cobalt-60 supply for critical uses like sterilization and cancer treatment. Nordion's investment in partnerships and technology aims to meet current and future Cobalt-60 demands.
