The idea of measuring the coherent elastic nuclear scattering of neutrinos emitted by a high intensity 51 Cr radioactive source is investigated. To produce the high intensity source, the radioactive material used in the GALLEX experiment (36 kg of Chromium 38.6% enriched in 50 Cr) could be reactivated to an intensity of few MCi. The advantages of this source are that the activity can be measured at few per mill level and that the neutrino spectrum is well known. With a target volume of 2 dm 3 of low-threshold detectors, if the background is limited, the crosssection might be measured with few percent precision. In this work the requirements for the experiment will be shown and the envisioned experimental challenges will also be discussed.
