| Abstract Scope |
There is an increased interest in using carbon composite materials for various reactor core applications due to advancements in material technologies and the development of high temperature micro reactors that require lower neutron dose environments. Vendors are increasingly more interested in using carbon composites due to their unique strength properties, engineered thermal response and high temperature tolerance. Historical data indicates that carbon composites do not tolerate high dose neutron environments well, while silicon-carbide composites have a more stable response. The ASME BPV-III-5 code introduces a pathway to qualify these materials for the use of nuclear reactors. However, the complex nature of ceramic matrix composites together with the combined dimensional instability caused by neutron irradiation, offer challenges when selecting materials. A new experimental irradiation study is underway to support designers with their initial screening of the various composite materials. The test matrix and applied small specimen test techniques will be discussed. |
