The major European electricity producers work on a common requirement docum
ent for future LWR plants since 1992. They aim at requirements acceptable t
ogether by the owners, the public and the authorities. Thus the designers g
n can develop standard LWR designs acceptable everywhere in Europe and the
utilities can open their consultations to vendors on common bases. Such a s
tandardisation promotes an improvement of generation costs and of safety; p
ublic and authorities acceptance should be improved as well; significant sa

ilities from two other European countries are joining the group. Specific c
ooperation agreements are also in progress with a few extra-European partne
