Title: Experimental status of geo-reactor search

Abstract: Existence of a natural nuclear fission reactor inside the Earth's core has been proposed as an energy source that powers Earth's magnetic field. Geo-reactor model implies existence of electron anti-neutrinos from the core with energy spectrum characterized by those produced in commercial fission reactors. The putative geo-reactor could be observed by the Kamioka liquid scintillator anti-neutrino detector (KamLAND) and its power, which is proportional to the rate of emission of anti-neutrinos, could be measured. Here we present the first attempt at detecting the geo-reactor power.
