Book Description
Progress in the Fluorox program is reported. The chemical reaction of primary interest in the Fluorox program is the oxidation of UF/sub 4/ with O/sub 2/, 2UF/sub 4/ + O/sub 2/ = UO/sub 2/F/sub 2/ + UF/sub 6/; however, to study this process at higher temperatures, the thermal decomposition of UO/sub 2/F/sub 2/, 3UO/sub 2/F/sub 2/ = 2/3 U/sub 3 /O/sub 8/ + UF/sub 6/ + 1/3 O/sub 2/, is being investigated by thermogravimetric methods in the temperature range 750 to 900 deg C.A fluidized bed reactor and a flame reactor have been used successfully to perform the continuous oxidation of UF/sub 4/ with O/sub 2/. The 3-in. fluidized bed reactor was operated up to 825 deg C on both a continuous and batch basis while the flame reactor was used to continuously react finely divided UF/sub 4/ with O/sub 2/ in a CO-O/sub 2/ flame at temperatures greater than 1200 deg C.

Book Description
NSA is a comprehensive collection of international nuclear science and technology literature for the period 1948 through 1976, pre-dating the prestigious INIS database, which began in 1970. NSA existed as a printed product (Volumes 1-33) initially, created by DOE's predecessor, the U.S. Atomic Energy Commission (AEC). NSA includes citations to scientific and technical reports from the AEC, the U.S. Energy Research and Development Administration and its contractors, plus other agencies and international organizations, universities, and industrial and research organizations. References to books, conference proceedings, papers, patents, dissertations, engineering drawings, and journal articles from worldwide sources are also included. Abstracts and full text are provided if available.

Book Description
The reaction of U0/sub 2/F/sub 2/ with hydrogen at 700 to 850 deg C was briefly investigated since it could constitute a major step in the recycle of U0/ sub 2/F/sub 2/ in the Fluorox process. The reaction in this temperature range proceeds according to the equation U0/sub 2/F/sub 2/ + H/sub 2/ yields U0/sub 2/ + 2 HF. Rates of the chemical reaction were not obtsined, since, with the thermogravimetric technique used, the rate-controlling process was bed diffusion. However, there is no doubt that the rate of chemical reaction is sufficiently high for the desired application. No significant amount of UF/sub 4/ was formed by the back-reaction, U0/sub 2/ + 4 HF yields UF/sub 4/ + 2 H/sub 2/0. (auth).
