Sure. We have opened a clean energy sorting and recycling centre with the support of McMaster University. It's something we're very proud of at OPG. During the pandemic we were able to open the facility, which is fully licensed and audited by the Canadian Nuclear Safety Commission. We bring our low-level waste to the facility where we sort and recycle.
Some of the very interesting preliminary findings we've had are that approximately 60% of the low-level waste that we store up at the Bruce site is actually medium free release targets. This means that we can eventually release it out from underneath the management of the low-level waste category.
We've also identified that the radioactivity that was originally measured and assigned with the waste has reduced significantly with time and the natural decay of the radioisotopes. On average, it's approximately 10% of the radioactivity that was originally there when we stored the waste. Over the period of 30 to 40 years, the waste has significantly decayed in terms of radioactivity.
The preliminary findings at McMaster will be finalized for us later this year, but it's quite interesting and applicable to our business.
