Research and development activities in the field of fluorine chemistry are summarized. Information is included on: synthesis of tetrafluorochlorates, formation of boron nitride and titanium oxides, properties and reactions of silicon fluorides and germanium fluorides, thermodynamic properties of fluorine compounds, and synthesis of halide compounds. (N.W.R.)

Separate abstracts were prepared for 18 of the 28 papers presented; 8 were previously abstracted in NSA. Topics covered include safety programs and philosophy, nuclear safety aspects of SNAP desigu and of propulsion reactor design, environmental factors, and re-entry and postmission disposal. (R.E.U.)

Information is presented on accidents andd incidents occurring during 1961 and 1962 in plants owned and operated by the AEC. Revised reporting requirements established by the AEC in April 1962 are outlined. Data are summarized on radiation exposure of AEC contractor personnel, accidents involving radioactive materials, andd accidents involving fatalities. (C.H.)

The requirements and potential applications for radioisotope and reactor SNAP systems are summarized. A technical review of the SNAP reactor programs, including the associated lithium cooled reactor experiment, is presented; and alternate approaches are evaluated. Radiation and safety considerations of isotopic SNAP systems are discussed, together with the economics of such systems and isotope availability. Characteristics and uses of SNAP systems are also tabulated. (D.C.W.)

Experimental and analytical investigations to determine the effects of irregular heat flow through reactor channels on the operating conditions that cause burnout (departure from nucleate boiling) are being planned. Tubular specimens having four axial power shapes and annular specimens having five power shapes will be used, and an effort to correlate the experimental data with empirical and analytical models will be made. The experimental program will be conducted on a vertical test section in a closed loop through which water is circulated at a given rate. A 1.8Mw d-c power supply will heat the test section. (auth)

Progress is reported in six sections on chemicalmetallurgical processing, fuel cycle applications of volatility and fluidization techniques, calorimetry, reactor safety, energy conversion, and routine operations. Separate abstracts were prepared for the first five sections. (D.L.C.)

Summaries of the computer programs initiated or modified are listed, and the programs developed for the GUS digital computer complex are described. Information included in bulletins or newsletters on computers is indicated, and the new routines for the IBM-704, IBM-1401, and GEORGE are listed. The computer equipment (including GEORGE) presently available for computations is briefly described. An automatic data processing system (CHLOE) was developed for spark chamber photograph analysis. It uses a fiber optics cathode ray tube scanner and an ASI-210 digital computer. (D.C.W.)

Experimental and analytical investigations are being conducted to determine the effects of irregular heat flow through reactor channels on the operating conditions that cause burnout (departure from nucleate boiling). Time was spent de signing, procuring, fabricating, and formulating plans in preparation for the initial test work. The bus bars, loop piping, and Test Section No. 1 were completed and installed except for the final connections. The primary elements for the instrumentation and control modifications are ready for installation. Considerable effort was expended to obtain a satisfactory supply source for the non-uniform test sections. It appears that the azimuthal variation of heat generation will be between plus or minus 2.5 to 5%. Procedures are being formulated for checking out the equipment and loop modifications prior to test operations. (auth)
