Power announced an uprate to 6,550 MWe. On March 23, 2022, Bruce Power announced an uprate to Unit 1 to 821 MWe On May 6, 2022, Bruce Power announced an uprate to Unit 2 to 823MWe, adding 39MW of capacity to the 784MWe it was producing previously. Other features on site There are more than 56 kilometres of roads on site, and at least 25 major structures. The site has its own fire department, laundry and medical centre. Douglas Point, 1960–1984 Encompassed by the Bruce site is the shut-down Douglas Point reactor, an earlier version of the CANDU design. Construction began in 1960; was operational in 1967; and was shut down in 1984. The present Bruce reactors each are roughly 4 times the capacity of the 200 MW Douglas Point unit. Bruce Heavy Water Plant, 1973–1997 The Bruce Heavy Water Plant (BHWP) also occupied the site. Atomic Energy of Canada Limited contracted the Lummus Company of Canada Limited in 1969 to design and construct the first phase of the plant, while Ontario Hydro was responsible for commissioning and operating. It was planned to consist of four sub-plants, A through D: A was in production in 1973, shutdown in 1984, and demolished in 1993; B was in production in 1979, partially shutdown in 1993, completely closed in 1997, and subsequently demolished; C was cancelled, and never built; D was 70% completed when cancelled, and subsequently demolished in 1995. During its lifetime, BHWP produced 16,000 tonnes of reactor grade heavy water. Capacity of each sub-plant was planned to be 800 tonnes/annum. The plant size was approximately 960 m by 750 m. The heavy water was 99.75% pure. The production of a single kilogram of heavy water required 340 tonnes of feed water. Bruce Bulk Steam System, 1972–2006 Steam from Bruce A could be diverted to the Bruce Bulk Steam System (BBSS) to provide energy for the production of heavy water (750 MW thermal), to heat buildings within the development (15 MW th), or to provide energy (72 MW th) for the adjacent Bruce Energy Centre (BEC). The BEC supported industries such as greenhouses and plastic manufacturers. As one of the largest bulk steam systems in the world, this system could produce 5,350 MW of medium-pressure process steam, and had over 6 km of piping. It was demolished by the end of 2006. Because of the requirement to provide steam, the Bruce A
