Properties of Unirradiated Graphites PGX, HLM, and 2020 for Support and Permanent Side Reflector LHTGR Components.

摘要

Graphite grades 2020, PGX, and HLM have been evaluated for LHTGR support posts, support floor blocks, and permanent side reflector components, respectively. Data are presented from the first phase characterization of five logs of grade 2020 and two logs each of grades PGX and HLM. The characterization data include bulk density, mechanical properties in tension, flexure and compression, thermal properties, and impurity content. The variations in properties within graphite logs and from log to log are also discussed. (ERA citation 04:005780)
