ABSTRACT: Multi-physics analyses, including coupled three-dimensional (3-D) neutron transport and full eld computational uid dynamics (CFD), represent the future in advanced modeling of reactor cores. 3-D neutron transport and full- eld CFD simulations provide highly re ned and accurate solutions based on rst principles. Such an approach incorporates the full spatial and temporal coupling of interrelated physical phenomena for more detailed reactor analysis. Ultimately, this provides an advanced analysis environment leading to improvements in the level of detail in modeling and reduction of uncertainties in reactor safety. A model of a pressurized water reactor (PWR) fuel pin was developed for a 3-D neutron transport calculation and a full- eld CFD calculation in support of the proof-of-concept for a coupled simulation tool. This work discusses the model requirements for predicting localized feedback e ects in a nuclear reactor using a multiphysics approach. All aspects of the coupling methodology are presented, including results from the independent models, initialization of the coupled calculation, and the data exchange between the codes.
Classroom Techniques to Help Students Engage with Content
Can your students encode critical information into their long-term memories? Academic standards call for increased rigor, but simply raising complexity is not enough. Students must also know how to retrieve critical information and comprehend key features of the content. Teachers must strategically impart the skills students need to authentically engage with content so they can effectively process the learning and store it for future use. Processing New Information: Classroom Techniques to Help Students Engage With Content explores explicit techniques for mastering a crucial strategy of instructional practice: processing new information. It includes: Explicit steps for implementation Recommendations for monitoring if students are able to process new information Adaptations for students who struggle, have special needs, or excel in learning Examples and nonexamples from classroom practice Common mistakes and ways to avoid them The Essentials for Achieving Rigor series of instruction

Collaborative Teams That Transform Schools: The Next Step in PLCs offers K-12 teachers and administrators a practical, comprehensive model of effective professional learning communities (PLCs). Authors Robert J. Marzano, Tammy Heflebower, Jan K. Hoegh, Phil Warrick, and Gavin Grift and contributors Laurel Hecker and Janelle Wills present a clear look at the future of the PLC process. Beginning with essential research and theory, they then detail the fundamental features of effective collaborative teams. Throughout the book, the authors go deeper to present guidelines and strategies readers can use to expand the responsibilities of collaborative teams.
