325-B FACILITY

Description: Due to the continuing high air sample results over the past six months, a thorough review of conditions and procedures was felt necessary for 325-B facility. A complete survey of the facility was made, looking for possible or definite problems. A discussion about procedures and conditions was held with all Radiation Monitoring personnel involved with the facility. The following items we felt needed attention to improve the working environment for the personnel in the facility. 1. Recommend glovebox be decontaminated and gloves changed to reduce dose rates. 2. Repair fume hood for proper airflow. 3. Move slurp jug inside fume hood and provide lead shielding. 4. Change storage of samples outside of cells to reduce dose rates. 5. Recommend contaminated waste from cells be bagged when removed through transfer tray. 6. Recommend fume hoods be installed at cell transfer trays. During a recent house cleaning, personnel in 325-B took action to correct items number 1 through 5, which leaves item number 6 to be considered. The need for fume hoods is based on high air sample results. These fume hoods would be very helpful in the unpackaging of contaminated samples. The removal of samples from the cell requires good air flow due to contamination levels.

ABSOLUTE ASYMMETRIC SYNTHESIS. I. ON THE MECHANISM OF THEPHOTOCHEMICAL ABSOLUTE ASYMMETRIC SYNTHESIS OF HELICENES WITH CIRCULARLYPOLARIZED LIGHT. . WAVELENGTH DEPENDENCE OF THE OPTICAL YIELD OFOCTAHELICENE.

Description: The synthesis of nonracemic yields of hexa-, hepta-, octa-, and nonhelicene with circular light was observed, and the structural and wavelength dependence of the induced optical yields was examined. The results obtained, together with a detailed consideration of the mechanism of helicene synthesis from the parent diarylolefins, indicate that the induced optical activity is due to selective reaction of enantiomeric conformations of the parent cis diarylolefins by circular light.

AFNOL synthesis. Quarterly report, October--December, 1971

Description: Five batches of unplasticized AFNOL, each approximately one pound, were synthesized using 4,4-dinitropimelic acid as the starting material. Two 10 g batches were completed prior to the pound batches to assure the usability of the acid chloride. Characterization of each of the larger batches was by differential thermal analysis (DTA), infrared spectrophotometry (IR), and cure tests. Some characterization was also done on the commercial chemicals used in the synthesis.
