The GUINEVERE project was launched in 2006 within the 6th Euratom Framework Program IP- EUROTRANS in order to study the feasibility of transmutation in Accelerator Driven subcritical Systems ADS . This zero-power facility hosted at the SCK CEN site in Mol Belgium couples the fast subcritical lead reactor VENUS-F with an external neutron source provided by interaction of deuterons delivered by the GENEPI-3C accelerator and a tritiated target located at the reactor core center. In order to test on-line subcriticality monitoring techniques the reactivity of
