Materials Compatibility Considerations for a Fusion-Fission Hybrid Reactor Design

The Tandem Mirror Hybrid Reactor is a fusion reactor concept that incorporates a fission-suppressed breeding blanket for the production of ²³³U to be used in conventional fission power reactors. The present paper reports on compatibility considerations related to the blanket design. These considerations include solid-solid interactions and liquid metal corrosion. Potential problems are discussed relative to the reference blanket operating temperature (490°C) and the recycling time of fissile materials (<1 year).
