Abstract
This paper presents an overview of the current and
planned technological activities at JET in support of
ITER operation and safety. The scope is very broad and it
ranges from analysis of components from the ITER-like
Wall (ILW) to determine material erosion and deposition,
dust generation and fuel retention to neutronics
measurements and analyses. Preliminary results are given
of the post-mortem analyses of samples exposed to JET
plasmas during the first JET-ILW operation in 2011-2012,
and retrieved during the following in-vessel
intervention. JET is the only fusion machine capable of
producing significant neutron yields, up to nearly 1019
n/s (14.1 MeV) in DT operations. Recently, the
technological potential of a new DT campaign at JET in
support of ITER has been explored and the outcome of this
assessment is presented. The expected 14 MeV neutron
yield, the use of tritium, the preparation and
implementation of safety measures will provide a unique
occasion to gain experience in several ITER relevant
technological areas. A number of projects and experiments
to be conducted in conjunction with the DT operation have
been identified and they are described in this paper
