But the Commission ultimately makes the decisions 17 HOW DOES THE CNSC ASSESS THE CLAIMS BEING MADE BY AN APPLICANT? • We use requirements and guidance contained in the CNSC’s regulatory framework • Requirements: “Shall”, “Must” – Based on proven fundamental safety principles: must be achieved to demonstrate an appropriate level of safety to a high degree of confidence • Guidance: “Should” – typically drawn from experience and past practice - information that needs to be considered in addressing requirements These form the starting point for an assessment regardless of the technology type and level of novelty 18 nuclearsafety.gc.ca WHAT ABOUT SMRs AS NEW TECHNOLOGIES? They will need to be proven to be effective and must still meet requirements. • The more important to safety they are, the higher the burden of proof (scientific data, modelling, testing) • Where there are knowledge gaps, an applicant will need to compensate

  • Nuclear Consultation. by Ricardo Acuna
    Issues: Another contentious issue, another phony consultation Nuclear Consultations Ricardo Acuña / ualberta.ca / parkland Why bother? Does anyone in Alberta really believe that "consultations" and "expert panel" reports generated by the provincial government are ever anything more than attempts to whitewash contentious issues and unpopular policies? Yet the government continues to spend millions of dollars on these public relations exercises, and continues to try to pass them off as genuine and objective consultations. The latest supposed information gathering and public consultation effort launched by the government is no different. When Albertans responded loudly and angrily to a proposal from Ontario's Bruce Power to build up to four nuclear reactors in northern Alberta, the government sought to quell the outcry by assuring us that they would not take a position on nuclear power without first studying the pros and cons in depth and fully consulting the public. As always, the first step in this process was the appointment of an "expert panel" to produce a "comprehensive and balanced" research report, which would look at the environmental, safety and myriad other issues related to nuclear power generation. Unfortunately, the panel itself was neither comprehensive nor balanced. The panel is chaired by Harvie Andre, a former Conservative MP who remains closely allied with pro-nuclear Conservatives, including Stephen Harper. Also on the panel is John Luxat, who is a past president of the Canadian Nuclear Society, and a current board member of Atomic Energy of Canada Limited (AECL). Rounding out the panel are Joseph Doucet, an energy policy professor from the University of Alberta, and Harrie Vredenburg, a prof from the University of Calgary who has done work in the past for energy companies holding a direct stake in Bruce Power.

  • The Use of Small Modular Nuclear Reactors for Canadian Oil Sands Applications: a Proposal and Way Forward
    The use of Small Modular Nuclear Reactors for Canadian Oil Sands Applications: A proposal and way forward By Dennis Attwood, P.Eng, Ph.D Principal, Human Factors Applications and Mohamed Moledina Senior Nuclear Engineer, Nuclear Energy Business Unit WorleyParsons Resources & Energy Canada 1. ABSTRACT It has been estimated that Canada’s Oil Sands contain between 160 and 200 billion barrels of oil reserves – the second largest accumulation of oil in the world after Saudi Arabia. It is also estimated that by 2015, output from the oil sands should increase from about 1 million barrels per day (mbbl/day)to approximately 4 mbbl/day. However, Canada and the world have to pay a price for oil extraction from the sands.It is estimated that about 40 cubic metres of natural gas as fuel must be burned for each barrel of synthetic crude produced. Therefore, if oil sands production did reach 4 mbbl/day,natural gas use for oil production could seriously limit exports of natural gas to the US. It has also been estimated that every barrel of synthetic oil pollutes about 950 litersof fresh water and emits about 100 Kg of Carbon Dioxode (CO2)along with other pollutants. Clearly an alternate source of energy is required for oil sands production that will allow our natural gas to be put to better use while simultaneously sustaining our environment. The energy must be continuously obtainable and not be subject to the intermittentavailability of wind or sunlight. Nuclear energy is the obvious choice. Nuclear energy for power generation has been prevalently used around the world since the 1950’s.

Nuclear fission is the common form of nuclear energy used currently. Nuclear fission is the process by which the nucleus of an atom (typically uranium) is split into two or more smaller atoms, while releasing energy.

  • Considerations in Recycling Used Natural Uranium Fuel from CANDU Reactors in Canada
    The 31st Annual Conference of the Canadian Nuclear Society CNS2010 UNRESTRICTED Montréal, Québec, Canada May 24 - 27, 2010 CW-124940-CONF-003 Rev. 0 Page 1 Considerations in Recycling Used Natural Uranium Fuel from CANDU Reactors in Canada P.G. Boczar1, J.T. Rogers2 and D.H. Lister3 1 Atomic Energy of Canada Limited, Chalk River Laboratories, Chalk River, Ontario, Canada 2Professor Emeritus, Carleton University, Ottawa, Ontario, Canada 3Professor Emeritus and Research Chair in Nuclear Engineering, University of New Brunswick, Fredericton, New Brunswick, Canada Abstract This paper identifies the key factors that would affect the recycling of used natural uranium (NU) fuel from CANDU reactors which are in operation in Canada and in several other countries. There has been little analysis of those considerations over the past 25 years and this paper provides a framework for such analysis. In particular, the large energy potential of the plutonium in used CANDU NU fuel provides a driver for consideration of used-fuel recycling. There would be a long lead-time (at least 30 years) and a large investment required for establishing the infrastructure for used-fuel recycling. While this paper does not promote the recycling of used CANDU NU fuel in Canadian CANDU reactors, it does suggest that it is timely to start the analysis and to consider the key factors or circumstances that warrant the recycling of used CANDU NU fuel. 1. Introduction From the earliest days of nuclear power, the recycling of fissile material in used fuel from conventional thermal reactors was seen as eventually being necessary to ensure long-term availability of fuel resources.
