Neutrino geophysics at Baksan I: possible detection of georeactor antineutrinos

J.M. Herndon in 90s proposed a natural nuclear fission georeactor at the center of the Earth with a power output of 3 - 10 TW as an energy source to sustain the Earth magnetic field. R.S. Raghavan in 2002 pointed out that under certain condition antineutrinos generated in georeactor can be detected using massive scintillation detectors. It is considered that underground Baksan Neutrino Observatory (4880 m w.e.) as a possible site dor development in Geoneutrino physics. Here the intrinsic background level of less than 1 event/yr in a liquid scintillation ∼1000-t target detector can be achieved and the main source of background is the antineutrino flux from power reactors. It is find that this flux is ∼ 10 times lower than at KamLAND detector site and two times lower than at Gran Sasso laboratory and thus at Baksan the georeactor burning nuclear fuel by analysis of the antineutrino energy spectrum
