This Subsection contains requirements for the material, design, fabrication, and examination required in the manufacture and installation of core support structures. Core support structures are those structures or parts of structures which are designed to provide direct support or restraint of the core (fuel & blanket assemblies) within the reactor pressure vessel. Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.<\/p>\n
