Criteria for low activation materials in fusion applications
Four criteria are proposed for defining low activation materials (LAMs), based on limits for the short and long term radioactivity. The first criterion proposes a 50 mSu limit for the early dose at 1000 m produced by the accidental release of a LAM. The second is that in order to perform prolonged maintenance operations within the plasma chamber, the dose rating inside the chamber should be limited to 10,000 Gy/h. The third and fourth criteria suggest limits for the contact dose rating and the decay heat of a LAM after disposal into a deep geological repository or alternatively after hands-on recycling. The materials investigated were reference steels, reduced activation steels and low activation alloys.
