[en] There is an opportunity to revisit first principles. new companies entering Canadian nuclear sector many from outside Canada with varying nuclear sector experience seeking to understand how to work within regulatory and industrial environment. Experienced Canadian nuclear companies are adapting themselves to engage in new build discussions. Being a competent plant operator is useful but is also different from overseeing design, construction, commissioning and operation of a new reactor concept. New technologies trying new technological approaches what practices are they expected to follow? How are they expected to demonstrate the practices they plan to use? When is an approach sufficiently proven to be acceptable for use? Who decides? What evidence is needed? When is it appropriate for a new practice to be codified?

[en] Highlights: • Validation of an Uncertainty Quantification method for CFD. • The input uncertainty is evaluated by Latin Hypercube and Deterministic Sampling. • The numerical uncertainty is obtained by Richardson extrapolation. • Downstream velocity and concentration are the subjects of Uncertainty Quantification. - Abstract: Computer simulations are frequently used for design and safety analyses of nuclear installations. In such computer simulations, uncertainties in the outcome are present, for instance, due to uncertainties in the input parameters of the analyses. It is important to assess and quantify these uncertainties, especially when the simulations form the basis for nuclear reactor safety or licensing. Quantification of the uncertainties in Computational Fluid Dynamics (CFD) analyses is currently seldom done, since the existing and robust way of Uncertainty Quantification (UQ) involves a large number of computations, and CFD computations are computationally very demanding. The long run-times and large computational efforts do simply not allow for thousands of CFD simulations. Therefore, smart UQ approaches for CFD are being tested, developed and validated at NRG, which allow a full quantification of the uncertainties, while the required number of computations is still acceptable. The UQ methodology used by NRG is based on the ASME Verification and Validation (V&V) standard for UQ in CFD applications, combined with a propagation technique to evaluate the input uncertainty, and Richardson extrapolation to evaluate the spatial discretization uncertainty. This CFD-UQ methodology proved to be efficient thanks to the Latin Hypercube Sampling (LHS) technique, which samples the uncertain input parameters prior to CFD propagation, in contrast to the computationally expensive and fully random Monte Carlo sampling (MCS) technique. Nevertheless, MCS and LHS are both Random Sampling (RS) techniques, which will always be affected to some degree by a random sampling error. Therefore, Deterministic Sampling (DS) techniques are tested in this work to evaluate the input uncertainty, instead of LHS. The DS techniques proved to be more efficient, producing similar results with less computations.

[en] The Graded Approach is a method or process by which elements such as the level of analysis, the depth of documentation and the scope of actions necessary to comply with requirements are commensurate with the relative risks to health, safety, security, the environment, and the implementation of international obligations to which Canada has agreed as well as the characteristics of a facility or activity. Our approach is driven primarily by assessment of the risk associated with the activities being regulated, and the performance history of the licensee. The degree of oversight is also informed by the complexity and potential harm posed by the licensed activity, technical assessments of submissions, relevant research, information supplied by parties to Commission proceedings, international activities that advance knowledge in nuclear and environmental safety and cooperation with other regulatory bodies

[en] J-Power, which is working on the construction of the Ohma Nuclear Power Plant, has developed the booklet 'What we should be' in order to promote the autonomous performance improvement of the staffs. We have redefined our vision and mission through its development. Then, to obtain a foundation (safety culture, etc.) necessary for achieving the vision, understand the framework (various performance improvement activities), and perform the work, the booklet is composed of contents that help sharing the following four points. 'Relationship among various activities for achieving vision', 'Mission and appropriate behavior of each section', 'Safety culture, values, professionalism, etc.', 'Performance improvement activities.' In this paper, we will introduce the purpose of the booklet, the development process, the outline of the booklet, the status of utilization, issues, and efforts for revision. (author)
