The detection of coherent-neutrino nucleus scattering opens up new opportunities to probe physics beyond the Standard Model such as the search for a neutrino magnetic moment or sterile neutrinos. We present a novel cryogenic neutrino experiment at a nuclear power reactor which allows for precision measurements with a miniaturized detector size. With a recent demonstrator we have achieved ultra-low thresholds of 20eV, one order of magnitude lower than previous devices, using a novel type of detector based on CRESST technology. We have initiated the NU-CLEUS experiment which aims to operate at close distance to a power reactor. A promising site about 80m away from the twin reactor cores of the CHOOZ power plant is currently being characterized by on-site background measurements with our French collaborators at CEA. This poster will report on the most recent results on the NU-CLEUS cryogenic detector, the ongoing background measurements at CHOOZ and the experimental strategy of NU-CLEUS.
