chemical reaction of the fuel cladding material zircaloy with hot steam during a
severe core melt accident. Also so-called hydrogen recombiners are distributed all
over the containment to decrease the hydrogen concentrations in the inner contain-
ment in case of slowly developing core melt accidents. In Chap.
8
the safety aspects
of rapid accident progressions with fast hydrogen generation will be discussed.
