tailieunhanh - Effect of central hole on fuel temperature distribution

In this study, a software program called MARCODE is developed in MATLAB environment that can analyze the temperature distribution, gap conductance value, and fuel and clad displacement in both solid and annular fuel rods. With a comparison of the maximum fuel temperature, fuel average temperature, fuel surface temperature, and gap conductance in solid and annular fuel, the effects of a central hole on the fuel temperature distribution are investigated. | Nuclear Engineering and Technology 49 2017 1629 1635 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage locate net Original Article Effect of central hole on fuel temperature distribution CrossMark Mehdi Yarmohammadi a Mohammad Rahgoshay a Amir Saied Shirani b a Department of Nuclear Engineering Science and Research Branch Islamic Azad University Daneshgah Blvd Simon Bulivar Blvd 1477893855 Tehran Iran b Faculty of Engineering Shahid Beheshti University Tehran Iran ARTICLE INFO ABSTRACT Article history Received 5 February 2017 Received in revised form 15 June 2017 Accepted 21 July 2017 Available online 18 August 2017 Reliable prediction of nuclear fuel rod behavior of nuclear power reactors constitutes a basic demand for steady-state calculations design purposes and fuel performance assessment. Perfect design of fuel rods as the first barrier against fission product release is very important. Simulation of fuel rod performance with a code or software is one of the fuel rod design steps.
