  In connection with the question of possible existence of sterile neutrino the
laboratory on the basis of SM-3 reactor was created to search for oscillations
of reactor antineutrino. A prototype of a neutrino detector with scintillator
volume of 400 l can be moved at the distance of 6-11 m from the reactor core.
The measurements of background conditions have been made. It is shown that the
main experimental problem is associated with cosmic radiation background. Test
measurements of dependence of a reactor antineutrino flux on the distance from
a reactor core have been made. The prospects of search for oscillations of
reactor antineutrino at short distances are discussed.
