Abstract
The (MEGAWatt Pilot Experiment) MEGAPIE target was successfully irradiated in 2006 at the SINQ facility
of the Paul Scherrer Institut. During the irradiation a series of measurements to monitor the operation
of the target, the thermal hydraulics behavior and the neutronic and nuclear aspects, has been performed.
In the post-test analysis phase of the project, the data were analyzed and important information relevant
to accelerator-driven systems (ADS) was gained, in particular: (i) from the operation of the target several
recommendations concern the simplification of the system and the improved reliability; (ii) data from
the thermal hydraulic measurements have offered the opportunity to validate the codes used in the
design phase; (iii) the neutronic analysis confirm the high performance of a liquid metal target and
the importance of the delayed neutron measurements in an ADS target; (iv) the nuclear measurements
of the gas released gave the opportunity to validate the codes used during the design phase and provided
indications for the operation. From the results in these different domains recommendations to further
development of ADS and heavy liquid metal targets are discussed.
