The final draft of a paper entitled The Oklo Reactors: Natural Analogs to Nuclear Waste Repositories has been submitted for publication. This paper discusses the chemical stability of the fossil reactors with respect to uranium, neodymium, ruthenium, and technetium, the transport of elements in the geologic environment at Oklo; and the geochemical conditions that may have influenced these processes. Measurements of barium isotopic ratios limit the abundance of fissiogenic barium to <10/sup -7/ g/g and <2 x 10/sup -6/ g/g in two samples peripheral of Oklo reactor zone 9. Samples from the Oklo mines have been sent to Australia for cooperative studies on the geochemistry of palladium, silver, cadmium, tin, and tellurium. Four samples representing a traverse to the east of reactor zone 9 are being analyzed to determine the isotopic composition of molybdenum and ruthenium.
