Nuclear Power Accidents By Country
Worldwide, many nuclear accidents and serious incidents have occurred before and since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US. The French Atomic Energy Commission ( CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation. Nuclear safety The nuclear power industry has improved the safety and performance of reactors, and has proposed new safer (but generally untested) reactor designs but there is no guarantee that the reactors will be designed, built and operated correctly. Mistakes do occur and the designers of reactors at Fukushima in Japan did not anticipate that a tsunami generated by an unexpected large earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake. According to UBS AG, the Fukushima I nuclear accidents have cast doubt on whether even an advanced economy like Japan can master nuclear safety. Catastrophic scenarios ...

Bruce Nuclear Generating Station
Bruce Nuclear Generating Station is a nuclear power station located on the eastern shore of Lake Huron in Ontario, Canada. It occupies 932 ha (2300 acres) of land. The facility derives its name from Bruce Township, the local municipality when the plant was constructed, now Kincardine due to amalgamation. With eight CANDU pressurized heavy-water reactors, it was the world's largest fully operational nuclear generating station by total reactor count and the number of currently operational reactors until 2016, when it was exceeded in nameplate capacity by South Korea's Kori Nuclear Power Plant. The station is the largest employer in Bruce County, with over 4000 workers. Formerly known as the Bruce Nuclear Power Development (BNPD), the facility was constructed in stages between 1970 and 1987 by the provincial Crown corporation, Ontario Hydro.

Pickering, Ontario
Pickering (2021 population 99,186) is a city located in Southern Ontario, Canada, immediately east of Toronto in Durham Region. Beginning in the 1770s, the area was settled by primarily ethnic British colonists. An increase in population occurred after the American Revolutionary War, when the Crown resettled Loyalists and encouraged new immigration. Many of the smaller rural communities have been preserved and function as provincially significant historic sites and museums. The city also includes the development of Durham Live, a multi-billion-dollar casino complex. History Early period The present-day Pickering was Aboriginal territory for thousands of years. The Wyandot (called the Huron by Europeans), who spoke an Iroquoian language, were the historical people living here in the 15th century. Archeological remains of a large village have been found here, known as the Draper Site. Later, the Wyandot moved northwest to Georgian Bay, where they established their historic homela ...

WR-1
The Whiteshell Reactor No. 1, or WR-1, was a Canadian research reactor located at AECL's Whiteshell Laboratories (WNRL) in Manitoba. Originally known as Organic-Cooled Deuterium-Reactor Experiment (OCDRE), it was built to test the concept of a CANDU-type reactor that replaced the heavy water coolant with an oil substance. This had a number of potential advantages in terms of cost and efficiency. The 60 MWth reactor was designed and built by Canadian General Electric for a cost of $14.5 million CAD. The construction started 1 November 1962. It achieved criticality on 1 November 1965 and full power in December 1965. An effort to commercialized the design began in 1971 but ended in 1973 when the heavy water cooled units became the standard. From then on WR-1 operated at reduced power limits for irradiation experiments and heating the WNRE site. WR-1 was shut down for the last time on 17 May 1985, was defuelled, and is undergoing decommissioning scheduled to be completed in 2023. ...

National Research Universal Reactor
The National Research Universal (NRU) reactor was a 135 MW nuclear research reactor built in the Chalk River Laboratories, Ontario, one of Canada’s national science facilities. It was a multipurpose science facility that served three main roles. It generated radionuclides used to treat or diagnose over 20 million people in 80 countries every year (and, to a lesser extent, other isotopes used for non-medical purposes). It was the neutron source for the NRC Canadian Neutron Beam Centre: a materials research centre that grew from the Nobel Prize-winning work of Bertram Brockhouse. It was the test bed for Atomic Energy of Canada Limited to develop fuels and materials for the CANDU reactor. At the time of its retirement on March 31, 2018, it was the world's oldest operating nuclear reactor. History The NRU reactor design was started in 1949. It is fundamentally a Canadian design, significantly advanced from NRX. It was built as the successor to the NRX reactor at the Atomic Energy ...

Iodine-131
Iodine-131 (131I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production. It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Fukushima nuclear crisis. This is because 131I is a major fission product of uranium and plutonium, comprising nearly 3% of the total products of fission (by weight). See fission product yield for a comparison with other radioactive fission products. 131I is also a major fission product of uranium-233, produced from thorium. Due to its mode of be ...
