Kel F-800 fluorocarbon polymer has been selected as the binder for the TATB explosive in the B77 bomb. Kel F-800 is a 3M copolymer derived from the monomers chlorotrifluorethylene (CTFE) and vinylidine fluoride (VF/sub 2/). To understand and define Kel F-800 in relation to its intended use, as well as to generate guidelines for controlling the WR material, a thorough evaluation of its properties and the expected variations from different production lots was made. The research showed that Kel F-800 varies in both mechanical and thermal properties because of its high Tg (glass transition temperature) and because of its crystallinity. However, no evidence that these variabilities are detrimental to any of the end-use properties of Kel F-800 was found.

In this phase of work the Process Development Unit is to be remodeled by incorporation of appropriate subsystems to permit operation in continuous process mode. The PDU will be operated for a period of time sufficient to demonstrate process viability. The modifications include the installation of ''Alonized'' pipe and equipment. A portion of the equipment to be ''Alonized'' was received from Alon Processing Inc. on June 27, 1977. The remainder of the order is expected about mid-July--some six weeks beyond the most optimistic delivery date. Computer modeling is complete except for instructions which anyone skilled in computer modeling could employ.

A program of making ''global'' fits to the large amount of experimental equation-of-state data on monatomic metals that has become available in recent years is described. The fits are made within the framework of a phenomenological scaling theory for metallic liquids which incorporates recently discovered general theoretical properties of the EOS of liquids. The theory is expected to be applicable to monatomic metals up to high temperatures (approximately 10 to 100 times the melting temperature, T/sub m/) and at all densities, so long as the metallic bonding does not change character.

The molar absorbanceted by the RSI/TRANCO finite-element computer code and results obtained by ORNL personnel for the Lyons, Kansas site. A determination of the transient temperature field for the room and pillar configuration that is proposed for the New Mexico pilot-plant site is included along with an analysis of the thermoelastic stress distribution in the near-field vicinity of the sleeve-waste container at the New Mexico pilot-plant site.
