Accelerator Driven system (ADS) are being considered for their potential use in the transmutation of nuclear waste. Such a device typically requires a 600MeV to 1GeV accelerator delivering a beam of few mA intensity. Because of the induced thermal stress to the subcritical core, the high-power proton LINAC will have to fulfill stringent reliability requirements, with less than a dozen of unwanted beam trips per year. One working package of the EUROTRANS project* is dedicated to the design, realization and tests of a prototypical cryomodule for the LINAC high energy section equipped with a 5 cells superconducting cavity and its tuning system. Developed at INFN, this RF cryogenic device will be tested at IPNO, early 2010. We will describe the status of the R&D activities, regarding the cryogenic system, the cavity, the power coupler, the doorknob transition and the RF source developed by Thales Electron Devices. Then, we will review the foreseen experimental reliability characterization of the cryomodule with its RF control system in nominal operating conditions.
