The Tritium Laboratory Karlsruhe (TLK) has been mainly designed for the con
duction of technological experiments relevant to fusion under simulation of
the conditions actually expected in the various tritium processing systems
. Presently ongoing experimental and design work is almost exclusively orie
nted towards the needs of JET and ITER-H-FEAT. Basic research, while increa
sing in importance, plays predominantly a complementary role. This paper pr
esents the most recent progress and developments related to the technologic
al and applied experiments at the TLK. (C) 2000 Elsevier Science B.V. All r
