PBMR REACTOR DESIGN AND DEVELOPMENT

摘要

The PBMR reactor is the first pebble bed reactor that will be utilised in a high temperature direct Braytoncycle. This leads to a number of unique challenges. The impact of these challenges on the structural design of thereactor and its subsystems are discussed. The reactor design and especially the design of the Core Structures aredescribed. This design description covers the functional requirements, structural arrangement and features ofthese subsystems and their components. The design of the reactor results in components utilizing design codesand materials that are currently available.
