[en] Interactive teaching tools have been designed and built to provide a new means for teaching a general audience about nuclear physics. The tools connect the chart of the nuclides to the energy released from nucleosynthesis in stars, and focus on the proton-proton chain and Carbon-Nitrogen-Oxygen (CNO) cycle stellar fusion reactions.

[en] Even though they may appear simple to working-level staff, decisions to implement major programs like Second License Renewal involve numerous considerations, and are typically made at the Board Level of a company. These include considerations involving regulatory framework, technical readiness, policy and politics, and economics. Mr. Coward will discuss those considerations from the perspective of senior leadership, and in the process summarize the status, outlook, and future of Second License Renewal in the US.
[en] A code developed by the authors to calculate nuclear fuel cycle parameters for Pressurized Heavy Water Reactors (PHWR) is presented. This paper explains how to use the code, which can calculate the average burnup (MWd/t) and fuel utilization (%) for various fuel compositions involving uranium, plutonium and thorium in a PHWR with a constant flux and online re-fueling interval. Potential benefits of alternative fuel cycles involving PHWRs and international fuel management practices are discussed. (author)
[en] Especially in controversial industry settings, the importance of stakeholder relationships signals a need for greater attention to the role of listening. We use a qualitative approach to learn from women's first-hand experiences of stakeholder listening in a nuclear industry context. Our preliminary analysis from 18 in-depth interviews highlights a variety of stakeholder perspectives on what it means to listen. We further explore the connections between listening and respect, identifying two distinct patterns of non-listening that appear in different contexts. (author)
[en] Despite garnering greater attention in academic literature, uncertainties persist regarding how SLO translates from theory to practice, particularly in the area of gendered perceptions of this concept. By drawing on original qualitative data collected through interviews with a diverse group of female stakeholders this paper seeks to explore varying understandings of this concept. (author)
[en] This paper describes a study on the effect of radiation on the corrosion of pure Ni at different temperatures and pH. Corrosion potential measurements and coupon corrosion tests have been performed on Ni samples in deaerated sodium borate solutions at pH 6.0, 8.4 and 10.6. Results show that radiation increases the oxidation rate, in both oxide formation and metal dissolution pathways. (author)
[en] The objective of this paper is a comparison, of a number of heat-transfer correlations based on forced-convection data obtained in supercritical refrigerants: R-22 and R-134a. This paper is also intended to act as a collection of both heat-transfer correlations and sources of the experimental refrigerant data in order to be a reference for future research. Results of this paper show that the most accurate correlations are by Cheng et al. and Watts and Chou, when predicting forced-convection data obtained in R-22 and R-134a. (author)
[en] This research is focused on understanding the damage structures generated in irradiated materials, of application to components within nuclear power plants. We carry out molecular dynamics (MD) simulations to model the effect of a high-energy impact by neutrons. We use both a model of dislocation energy and MD to explore the habit planes of -type dislocation loops, while cascade simulations are produced to investigate the effect of irradiation on those loops. Using MD/Monte Carlo simulations, the role of Ni-based precipitates on the stability of dislocation loops and their distribution are elucidated in Zr-rich alloys. (author)
[en] The Advanced Fuel CANDU Reactor (AFCR) is an innovative design that is uniquely positioned to play a key role through its use of recycled uranium and thorium-based fuels. The synergistic utilization of recycled uranium from Light Water Reactors (LWRs) creates a near-term path towards closing the fuel cycle, while the deployment of thorium-based fuels increases resource diversification and overall fuel sustainability. The discussion will focus on the strategic cooperation with China to bring this technology to market and the future roadmap for AFCR development over the next several decades.
[en] The main reason the nuclear industry has not met its full potential is the negative public perception associated with it. In order to grow the industry, the discussion needs to shift from reacting to nuclear bombs and very visible disasters to getting people excited about nuclear and its potential. By holding nuclear videoconferencing outreach events for high school students, we could excite them about nuclear and entice them into the industry. A Canadian nuclear outreach event allows students to experience nuclear regardless of where they are located and could attract them into a nuclear career. (author)
