ii - Regulatory Oversight Report for Uranium Mines and Mills in Canada: 2014 EXECUTIVE SUMMARY This report presents the performance of the operating uranium mine and mill facilities regulated by the Canadian Nuclear Safety Commission (CNSC). It covers the 2014 calendar year and, when applicable, shows trends and compares information to previous years. Furthermore, it includes information on the CNSC’s Independent Environmental Monitoring Program, follows up on the two 2015 Key Lake calciner events, and incorporates changes from Commission member recommendations made during the Commission meeting for the Regulatory Oversight Report for Uranium Mines and Mills in Canada : 2013 . The report focuses on the three safety and control areas (SCAs) of radiation protection, environmental protection and conventional health and safety, which cover the key performance indicators for these facilities. The report also highlights rating changes for all 14 SCAs, along with major events and significant facility modifications. Finally, it describes measures taken by licensees, the CNSC and other regulatory bodies to protect the environment, and the health and safety of the public and workers. Evaluations conducted by CNSC staff concluded that uranium mine and mill facilities in Canada operated safely during 2014 and met the following performance expectations: . Radiation protection measures were effective and doses remained as low as reasonably achievable (ALARA), and well below the regulatory limit. Conventional health and safety programs continued to protect workers. The environmental protection programs were effective, with all spills cleaned up appropriately with no residual impact to the environment. This conclusion was based on assessments of licensee activities, site inspections, reviews of reports submitted by licensees, event and incident reviews, Commission hearings and meetings, and ongoing exchanges of information with licensees. - 1 - Regulatory Oversight Report for Uranium Mines and Mills in Canada: 2014 >This page was intentionally left blank< - 2 - Regulatory Oversight Report for Uranium Mines and Mills in Canada: 2014 REGULATORY OVERSIGHT REPORT FOR URANIUM MINES AND MILLS IN CANADA: 2014 1 Introduction 1.1 Background The Regulatory Oversight Report for Uranium Mines and Mills in Canada: 2014 summarizes the Canadian Nuclear Safety Commission (CNSC) staff’s assessment of the safety performance

    ACCIDENTS, LEAKS, FAILURES AND OTHER INCIDENTS IN THE NUCLEAR INDUSTRIAL AND MILITARY 1. 1947, October - U.S.A., ATLANTIC OCEAN A retired navy pilot Lieutenant-Commander George Earl IV has claimed that he dumped radioactive Waste off the Atlantic seaboard on three flights in 1947. Lt-Commander Earl said he disclosed the radioactive dumping because of the U.S. Government's apparent lack of concern over the possibility of the cannisters leaking. ("The West Australian" - 3rd January 1981) 2. 1950, 13th February - U.S.A., PACIFIC OCEAN A B-36 which developed serious mechanical difficulties on a simulated combat mission, dropped a nuclear weapon from 8,000 ft. over the Pacific Ocean before crashing. Luckily only the weapon's explosive material detonated. Nothing is known of attempts to recover the nuclear weapon and presumably it is still in the ocean. (The Defence Monitor Vol.X No.5 1981 Washington D.C. "The National Times" 15th March 1981) 3. 1950, 11th April - NEW MEXICO, U.S.A. A B-29 crashed into a mountain on Manzano Base approximately three minutes after take-off. The bomb case was demolished and some high explosive material burned. The nuclear components of the weapon were recovered and returned to the Atomic Energy Commission. (The Defence Monitor - Vol.X No.5 19981 Washington D.C. "The National Times" 15th March 1981) 4. 1950, 13th Jul. - OHIO, U.S.A. A B-50 on training mission crashed killing 16 crewmen. The high explosive portion of the weapon aboard detonated on impact. No nuclear capsule aboard the aircraft.

  • Uranium in Saskatchewan
    Uranium in Saskatchewan Uranium in Saskatchewan Facts on the Industry for 2017 Attached are fact sheets containing information about the uranium industry in Saskatchewan, prepared by the Saskatchewan Mining Association. These fact sheets identify the companies, operations and projects involved in the uranium industry as well as the industry’s historical economic impact within the province. If you have any questions, please contact the appropriate person listed under Industry Contacts. If it is not clear whom you should contact, please call the media and public relations people listed. Uranium in Saskatchewan Introduction “Uranium in Saskatchewan” is a series of fact sheets produced annually by Saskatchewan’s uranium mining industry. The information contained has been gathered from corporations producing uranium in the province. The fact sheets represent the combined total of all efforts of the companies, their employees and contractors who produce this valuable source of energy used worldwide to generate electricity. Saskatchewan is a world leader in uranium production. The uranium industry provides many jobs and promotes investment and economic development in the province. The Saskatchewan uranium mining industry is one of the top employers of aboriginal people in Canada. The industry provides all of these benefits in an environmentally and socially responsible manner and is held accountable for its performance. Regular internal and external audits on the environment and safety of operations are ongoing and thousands of air, water and vegetation samples are taken annually. These samples demonstrate that the industry is protecting the environment. These fact sheets illustrate the magnitude of this industry and the benefits that accrue to the people of Saskatchewan.

Ce gisement de 1,3 milliard d'années se trouve à une profondeur d'environ 450 m, sous la surface, dans un grès saturé d'eau au contact de la discordance avec les roches métamorphi- ques Précambriennes du Bouclier canadien. Le minerai d'uranium, qui contient principale- ment de l'uraninite (UO2), est entouré d'un halo riche en argile aussi bien dans le grès que dans le socle, reste très bien conservé et intact. La teneur moyenne du minerai est d'environ 8 % en poids d'U; localement, la teneur peut atteindre d'environ 55 % en poids d'U. Le gisement de Cigar Lake comporte de nombreux éléments qui sont équivalents à ceux en cours d'examen dans le contexte du concept canadien de stockage permanent des déchets de combustible nucléaire.
