it is decommissioned in 2018. OPG and Bruce Power are collaborating on an effort to expand 60Co production to the Bruce A and Darlington reactors in order to fully cover Pickering's production (which will end when the plant is decommissioned in 2024) in addition to the inevitable gaps in 60Co production capacity that will be caused by the upcoming refurbishments of six of Bruce's reactors (Units A 3–4 & Units B 5–8), as well as all four of Darlington's reactors. They are also working on expanding the production of HSA 60Co to more reactors. In 2017, Bruce Power became the first Canadian recipient of a Top Innovative Practice (TIP) award from the Nuclear Energy Institute (NEI) for its ongoing work with Nordion to produce cobalt-60. Radioisotope production project Bruce Power is working with Framatome to develop the capability to "produce shorter half-life radioisotopes (such as molybdenum-99, lutetium-177 and iridium-192)" using Areva's proprietary technology for the on-line production of radioisotopes in heavy water reactors. Areva will design and supply the system for installation in the existing Bruce units. In June 2018, Bruce Power and ITG (a subsidiary of Isotopen Technologien München (ITM)) announced the start of a joint effort to explore producing lutetium-177 in Bruce's reactors, with ITG planned to manage the development, processing, and distribution of lutetium-177. The initial Isotope Production System (IPS), producing Lu-177, came online in January 2022. Refurbishment of Units 1–2, 1995–2012 Retubing of Bruce A units was planned in 1992, but deferred, as Ontario Hydro had a surplus of generation at the time. In late 2005, Bruce Power and the Government of Ontario committed to return units 1 and 2 to service, to help meet increasing energy demand in the province of Ontario. The project was originally estimated to cost $4.25 billion. It was determined that while units 1 & 2 could have been restarted without refurbishment, it was economically advantageous to do so, since refurbishment would have been soon required. The goal is to keep units 1 & 2 in service until 2043, 66 years after original commissioning. The refurbishment required pressure tube and calandria tube replacement, steam generator replacement, shutdown System 2 (SDS2) enhancement, an upgrade of turbine control systems, replacing original analog controls with a DCS and significant other work and maintenance (for example, replacement of 30 transformers containing PCBs). A new fuel bundle design (Low Void Reactivity Fuel, LVRF) was considered, using
