NUCLEAR REACTOR ALIGNMENT PLATE CONFIGURATION

摘要

This invention achieves the foregoing objective by providing a pressurize d water nuclear reactor having a pressure vessel with a core region for supp orting fuel assemblies A core barrel Is removably disposed within the pressu re vessel around the core region A core shroud is disposed within the core b arrel between the core barrel and the fuel assemblies The core shroud has an alignment slot that orients the core shroud with the core barrel An upper s upport plate is removably disposed above the fuel assemblies and the core sh roud The upper core support plate also has an alignment slot for aligning th e upper core support plate with the core barrel and the core shroud An align ment plate Is attached to the core barrel and is disposed within the alignme nt slot of the core shroud and within the alignment slot of the upper core s upport plate to maintain alignment
