    Our solar system
    About 5 billion years ago, the temperature and pressure at the centre of our sun became sufficient to induce nuclear fission. Soon after the formation of the planets about 4.8 billion years ago, Earth melts due to radioactive heating, gravitational collapse and heavy meteorite bombardment. The dense particles sink and the densest of them, including uranium, thorium and any remaining plutonium, collect at the very centre of Earth.

    Rutherford offers insight into nuclear energy
    At McGill University, Sir Ernest Rutherford demonstrates that alpha particles are helium atoms and determines their decay series. He coins the term "half-life" and prophetically states, in his book Radio-Activity: "There is reason to believe that an enormous store of latent energy is resident in the atoms of radioactive elements… If it were ever possible to control at will the rate of disintegration of the radioelements, an enormous amount of energy could be obtained from a small quantity of matter.” In 1908, Sir Ernest Rutherford would go on to win the Nobel Prize for Chemistry for his work in radioactivity.

    Radium Girls
    The Radium Girls are a group of female factory workers who contract radiation poisoning from painting watch dials with glow-in-the-dark paint at the United States Radium factory in Orange, New Jersey around 1917. The women, who had been told the paint was harmless, ingest deadly amounts of radium by licking their paintbrushes to sharpen them; some also paint their fingernails with the glowing substance. Five of the women challenge their employer in a court case that consequently establishes the right of individual workers who contract occupational diseases to sue their employers.

The MAPLE concept featured an H2O-cooled and D2O-reflected core, and would have operated with a thermal power of 5 to 40 MW(th). It offered a high thermal neutron flux, small core volume, and accommodation for multiple beam-tubes and in-core experimental sites, as well as driven spectrum-specific facilities in the reflector (cold-neutron source, fast-neutron flux trap, etc.). Two MAPLE reactors were constructed for isotope production at AECL's Chalk River laboratories, for MDS Nordion, a radiopharmaceutical supplier. These 10-MW(th) reactors were intended to replace the isotope-production capability of AECL's NRU reactor. For a variety of reasons (technical, financial, managerial, political, regulatory), the MAPLE Medical Isotope Reactor (MMIR) project was abandoned on May 16, 2008. The NRU remains in operation as both a research reactor and supplier of medical radioisotopes.

    The CNSC holds public hearings on the shipment of 16 used steam generators
    The CNSC holds a public hearing on Bruce Power’s application to package and transport 16 steam generators through the Great Lakes and St. Lawrence Seaway to Sweden for recycling. Initially non-radioactive, the bus-sized steam generators become contaminated on the inside with low levels of radioactivity during their service life. Through the licensed Swedish facility, the generators would be recycled such that 90% of the metal could be decontaminated and sold as scrap, leaving 10% of the original volume returned to the licensee for storage. The CNSC conducts a thorough environmental review under the NSCA and concludes the shipment to be low risk. However, in light of public concern about the potential impact on health and the environment, the CNSC decides to hold a public hearing to allow the public to be heard before the Commission Tribunal, and to facilitate the presentation of accurate information relating to the health and safety risks of the proposed shipment. Seventy-seven intervenors take part at the hearing. (Source: CNSC)

    Massive earthquake and tsunami lead to severe damage of Fukushima Daiichi reactors in Japan
    An earthquake measuring 9.0 on the Richter scale strikes Japan. Thousands of people lose their lives in the earthquake and resulting tsunami. At the Fukushima Daiichi nuclear power station, the earthquake causes severe damage to the reactors. The 15-metre tsunami – twice the height of any previously recorded in the region – also knocks out generators powering the cooling systems of the Fukushima Daiichi nuclear power station . People are evacuated 20 kilometres from the site. Heat and pressure build up in the reactors and lead to explosions and leaks. To cool the reactors and spent fuel storage pools, nuclear energy and emergency workers drop sea water and then fresh water on the reactors, install diesel generators, and seek ways to prevent this water, now contaminated, from flowing into the sea. Japan rates the nuclear power station event as level 7 on the International Nuclear and Radialogical Events scale – the highest level and only once previously recorded at Chernobyl in 1986. While cooling efforts gradually see results, the area surrounding the plant remains highly toxic. Radioactivity levels are also monitored elsewhere in Japan and around the world. (Source: CNSC)
