The CDT project aimed at going further:
 Starting from the outcome of different FP projects (PDS-XADS,
EUROTRANS) and national initiatives (MYRRHA),
 Obtain a more advanced design of a flexible irradiation facility,
FASTEF, able to work in both sub-critical and critical mode,
 Setting also up a centralised multi-disciplinary team, based at
Mol for its core group,
 Concentrating on primary and core systems and on reactor
building design & plant layout,
 The project started in April 2009 for a duration of 36 months.

Building design & plant layout have been optimized:
 The plant comprises a front-end accelerator building, a LINAC
tunnel, a RF gallery, a reactor building (total length about 450 m)
and several auxiliaries; room should be kept for future extensions;
 Within the reactor building, several workflows have been
considered (entry of experiments, fuel & components; evacuation
of experiments & commercial productions, spent fuel & waste);
 Short-term activities (production of medical radioisotopes &
silicon ingots) should not interfere with long-term operations
(irradiations);
 So the whole facility should be versatile and flexible, therefore
complex.

Conclusions
 MYRRHA is conceived as a flexible fast spectrum irradiation facility;
 Able to work in sub-critical and critical mode; foreseen to be in full
operation by 2024;
 Operated in the first years as an Accelerator Driven System
 to demonstrate the ADS technology and
 the efficient demonstration of Minor Actinides in subcritical mode.
 In function of needs, MYRRHA can also work as a critical flexible fast
spectrum irradiation facility.
 MYRRHA will be able to significantly contribute to the development of
LFR Technology;
 Will play the role of European Technology Pilot Plant in the roadmap for
LFR.
 This project is intended to be organised as an international open user
facility.
