The difference between the first wall and plasma-facing

[Edward33]

I have read an article talking about material research in fusion. One part in the context is divided into three aspects about the material capable of using in a fusion power reactor. Material selection in the first wall and plasma-facing components are two of the aspects. But it does not mention the difference between them. Thanks for any advice.

The first wall is a mechanical structure that is composed of many different components. The plasma facing components are the parts of the first wall that face the plasma.
