Using modern methods of reactor physics, we performed full-scale calculations of the Oklo natural reactor. For reliability, we used recent versions of two Monte Carlo codes: the Russian code MCU-REA and the well-known international code MCNP. Both codes produced similar results. We constructed a computer model of the Oklo reactorzone RZ2whichtakesintoaccountalldetailsofdesignandcomposition.Thecalculationswereperformed for three fresh cores with different uranium contents.

Oklo reactors and implications for nuclear science
We summarize the nuclear physics interests in the Oklo natural nuclear reactors, focusing particularly on developments over the past two decades. Modeling of the reactors has become increasingly
Criticality of Oklo Natural Reactors: Realistic Model of Reaction Zone 9
Explanation of the so-called Oklo phenomenon can only be found by associating neutron physics and geological observations. The framework of Reactor Zone #9 (RZ9) from the Oklo uranium deposit in
Investigation of the fundamental constants stability based on the reactor Oklo burn-up analysis
The burn-up of few samples of the natural Oklo reactor zones 3, 5 was calculated using the modern Monte Carlo code. We reconstructed the neutron spectrum in the core by means of the isotope ratios:
Effects of the variation of fundamental constants on Population III stellar evolution
Aims. A variation of the fundamental constants is expected to affect the thermonuclear rates important for stellar nucleosynthesis. In particular, because of the very low resonant energies of 8Be and
The variation of the fine structure constant: testing the dipole model with thermonuclear supernovae
The large-number hypothesis conjectures that fundamental constants may vary. Accordingly, the space-time variation of fundamental constants has been an active subject of research for decades.
Spatial variation of fundamental constants: Testing models with thermonuclear supernovae
Since Dirac stated his Large Number Hypothesis the space-time variation of fundamental constants has been an active subject of research. Here we analyze the possible spatial variation of two

The dependence of the effective neutron multiplication factor on the thickness, the radius, the porosity and the uranium content of the reaction zone was investigated by means of the design of experiments method in order to establish a new set of limit values corresponding to critical configurations.
Monte-Carlo Based Numerical Modeling and Simulation of Criticality Conditions Occurrence in Natural Reactor Zone 9 in Oklo Deposit (Gabon)
The occurrence of the criticality with analogue modelled configurations of the fossil reactor zone n°9 (RZ9) from Oklo uranium deposit in Gabon is studied. The RZ9 and the other reaction zones 7 and
Current and future constraints on extended Bekenstein-type models for a varying fine-structure constant
There is a growing interest in astrophysical tests of the stability of dimensionless fundamental couplings, such as the fine-structure constant $\alpha$, as an optimal probe of new physics. The
Dynamical dark energy and variation of fundamental "constants"
In this thesis we study the influence of a possible variation of fundamental "constants" on the process of Big Bang Nucleosynthesis (BBN). Our findings are combined with further studies on variations


The nuclear interaction at Oklo 2 billion years ago
Abstract We re-examine the effort to constrain the time variability of the coupling constants of the fundamental interactions by studying the anomalous isotopic abundance of Sm observed at the
The Oklo bound on the time variation of the fine-structure constant revisited
Abstract It has been pointed out by Shlyakhter that data from the natural fission reactors which operated about two billion years ago at Oklo (Gabon) had the potential of providing an extremely tight
Geochemical and Neutronic Characteristics of the Natural Fossil Fission Reactors at Oklo and Bangombé, Gabon
Isotopic studies have been completed on samples from the natural fission reactors at Oklo and Bangombe in order to determine the conditions under which they functioned when critical and to evaluate
Record of cycling operation of the natural nuclear reactor in the Oklo/Okelobondo area in Gabon.
Nature not only created conditions for self-sustained nuclear chain reactions, but also provided clues on how to retain nuclear wastes, including fission Xe and Kr, and prevent uncontrolled runaway chain reaction.
