Natural nuclear fission reactor had operated as a natural fission reactor. Other observations led to the same conclusion, and on September 25, 1972, the CEA announced their finding that self-sustaining nuclear chain reactions had occurred on Earth about 2 billion years ago. Later, other natural nuclear fission reactors were discovered in the region. Neodymium and other elements were found with isotopic compositions different from what is usually found on Earth. For example, Oklo contained less than 6% of the isotope while natural neodymium contains 27%; however Oklo contained more of the isotope. Subtracting the natural isotopic Nd abundance from the Oklo-Nd, the isotopic composition
