The DANSS project is aimed at creating a relatively compact neutrino spectrometer which does not contain any flammable or other dangerous liquids and may therefore be located very close to the core of an industrial power reactor. As a result, it is expected that high neutrino flux would provide about 15,000 IBD interactions per day in the detector with a sensitive volume of 1m(3). High segmentation of the plastic scintillator will allow to suppress a background down to a similar to 1% level. Numerous tests performed with a simplified pilot prototype DANSSino under a 3GW(th) reactor of the Kalinin NPP have demonstrated operability of the chosen design.

The DANSS detector surrounded with a composite shield is movable by means of a special lifting gear, varying the distance to the reactor core in a range from 10m to 12 m. Due to this feature, it could be used not only for the reactor monitoring, but also for fundamental research including short-range neutrino oscillations to the sterile state. Supposing one-year measurement, the sensitivity to the oscillation parameters is expected to reach a level of sin(2)( 2 theta (new)) similar to 5 x 10(-3) with Delta m(2) subset of (0 : 02-5 : 0) eV(2).
