Geoantineutrino spectrum and slow nuclear burning on the boundary of the liquid and solid phases of the Earth's core

Abstract

[1] We give an alternative description of the data produced in the KamLAND experiment. Assuming the existence of a natural nuclear reactor on the boundary of the liquid and solid phases of the Earth's core, a geoantineutrino spectrum is obtained. This assumption is based on the experimental results of V. Anisichkin and his collaborators on the interaction of uranium dioxide and uranium carbide with iron-nickel and silica-alumina melts at high pressure (5-10 GPa) and temperature (1600-2200°C), which led to the proposal of the existence of an actinide shell in the Earth's core. We describe the operating mechanism of this reactor as solitary waves of nuclear burning in 238 U and/or 232 Th medium, in particular, as neutron fission progressive waves of Feoktistov and/or Teller et al. type. Next, we propose a simplified model for the accumulation and burn-up kinetics in Feoktistov's U-Pu fuel cycle. We also apply this model for numerical simulations of neutron fission wave in a two-phase UO 2 /Fe medium on the surface of the Earth's solid core. The proposed georeactor model offers a mechanism for the generation of

Traveling Wave Reactor and Condition of Existence of Nuclear Burning Soliton-Like Wave in Neutron-Multiplying Media

“…With that end in view we have compared the Gaussian ensemble statistics (41) with well-known computational experimental data [8,[23][24][25][26][27] and have obtained a good accordance of calculation data with the theoretical dependence, which is described by the Gaussian symplectic ensemble statistics (see Table 1 and Figure 4). Thus, we can conclude that the wave velocity u (see Equation (34)) is predetermined by the following approximate equality…”

“…The corresponding system of differential equations, which describes the kinetics of Feoktistovs U-Pu fuel cycle with consideration of delayed neutrons, i.e., the kinetics of initiation and propagation of neutron-fission wave n(x, t), is as follows [23] ∂n(x, t) ∂t…”

Geoneutrino Measurements and Models Investigate Deep Earth

“…KamLAND data restrict the power of an Earth-centered georeactor to be less than 20% of the terrestrial heat flow [Abe et al, 2008]. This eliminates some georeactor models [Rusov et al, 2007] yet allows others, including one recently highlighted model that suggests a georeactor at the core-mantle boundary [Ball, 2008]. An antineutrino detector operating at a location where the flux from human-made reactors is minimal, such as at Hanohano in the mid-Pacific, would be sensitive to georeactors with power as low as a few percent of the terrestrial heat flow.…”

Galactic cosmic rays—clouds effect and bifurcation model of the Earth global climate. Part 2. Comparison of theory with experiment

“…Now let us consider geophysical consequences induced by the significant increase of the Earth liquid core temperature. It is known that the induced fission cross-section of 238 U, which is the natural fuel for the georeactor (Rusov et al, 2007), strongly depends on the ambient temperature Т (σ f ~T 4 ) in the resonance region. It means that the nuclear burning rate on the boundary of the liquid and solid phases of the Earth core increases with ambient temperature growth.…”

“…Moreover, this low interaction between solar wind and the Earth magnetosphere is veiled by the intrinsic variations of the Earth's magnetic field due to the specificities of the Earth liquid core kinetics and the stochastic properties of magnetic field energy source, i.e. slow nuclear burning on the boundary of liquid and solid phases of the Earths core (the georeactor of 30 TW) (Rusov et al, 2007).…”
