Effect of bi-directional excitation input on boiling water reactor scrammability
Nihon Kikai Gakkai ronbunshu, 2020 When a large earthquake occurs, a boiling water reactor is automatically shutdown through the insertion of control rods among fuel assemblies. A fuel assembly can vibrate in-plane when two seismic waves act on it in directions at right angles to each ...

Fretting Wear and Fatigue Life Analysis of Fuel Bundles Subjected to Turbulent Axial Flow in CEFR
Science and Technology of Nuclear Installations, 2019 In a fast spectrum reactor, the fuel rod bundle is mainly positioned radially by the wire which can make contact with the adjacent fuel rods, and then it is inevitable that flow-induced vibration (FIV) will cause fretting wear and vibration fatigue of ...

HTGR fuel rod deconsolidation [PDF]
, 1978 High-Temperature Gas-Cooled Reactor fuel particles are bonded into rods by a carbonaceous matrix. In conjunction with the development of a system to determine fuel failure fractions from gamma analysis of individual particles, a technique was developed to separate the particles from the matrix after irradiation.

Influence of grid-to-rod fit on fuel rod fretting
Periodica Polytechnica Mechanical Engineering, 2013 The fretting behavior of nuclear fuel assemblies is influenced by a number of parameters. One of these is the fit between the fuel rod and the spacer grid, which changes during the fuel residence time in the core. The influence of fit on fretting has been investigated by performing model tests on a typical fuel rod support configuration.
