LWR Core Materials

  • J. T. Adrian Roberts
Part of the Modern Perspectives in Energy book series (MOAC)

Abstract

The key component of the fission reactor core is the fuel pellet. The other core materials are used either for structural support or for nuclear control, and both their amounts and their geometries are carefully controlled to ensure maximum efficiency of the fission reaction. Experience with LWR cores is extensive and has been widely published in several important meeting proceedings.(1–3) Early problems with fuel rods such as hydriding, clad collapsing, and unanticipated growth and fretting, which were mainly caused by inadequate design or manufacturing, have been eliminated. In this chapter, therefore, the intent is to focus on those material limitations that are under current study, and to only briefly summarize past developments.
