A low-temperature (750{degrees}C) process to produce aluminum, employing dimensionally-stable electrodes, was investigated under this contract. Tests were carried out at a 10-ampere scale to develop a nonconsumable anode and to evaluate certain cell operating parameters. The work was carried out in conjunction with a NSF SBIR research grant to study the fundamental science aspects of the process. A scaled up 300-ampere cell was built and a preliminary test run was made with encouraging results. The new technology has the promise of producing aluminum at 5.0 kWh/lb as compared to the US average of about 7.5 kWh/lb, and to produce it at lower cost. Preliminary technical discussions have been held with a major US aluminum company under secrecy agreement for eventual licensing.

The baseline risk assessment [WSRC91] has demonstrated that the hazard at PAR Pond is solely from external exposure to Cs-137, a gamma emitting radionuclide. Between 1954 and 1964, approximately 222 curies of radioactive cesium (Cs-134 and Cs-137) were released to the Lower Three Runs Creek system from R Reactor [Ma9l]. These releases were associated with leaking fuel and target slugs in the reactor disassembly basin. Independent studies show that approximately 45 curies of Cs-137 (half-life of 30 years) still resides in the sediments of PAR Pond [Wh9l; Wi9l]; Cs-134 has a relatively short half-life (2 years) and has decayed to insignificant quantities since it was released.

Research continued on relative biological effectiveness, in the following areas: radial distribution of dose about the path of an energetic heavy ion; the response of E. Coli mutants to ionizing radiations; the application of a fragmentation model to to the calculation of cell survival and mutation with heavy ion beams; biological radiation effects from gamma radiation and heavy ion beams on organisms; cancer induction in the Harderian Gland by HZE particles; and effects of low dose radiations.

The Solenoidal Tracker At RHIC (STAR) will search for signatures of quark-gluon plasma (QGP) formation and investigate the behavior of strongly interacting matter at high energy density. The emphasis win be the correlation of many observables on an event-by-event basis. In the absence of definitive signatures for the QGP, it is imperative that such correlations be used to identify special events and possible signatures. This requires a flexible detection system that can simultaneously measure many experimental observables. The physics goals dictate the design of star and it's experiment. To meet the design criteria, tracking, momentum analysis, and particle identification of most of the charged particles at midrapidity are necessary. The tracking must operate in conditions at higher than the expected maximum charged particle multiplicities for central Au + Au collisions. Particle identification of pions/kaons for p < 0.7 GeV/c and kaons/protons for p < 1 GeV/c, as well as measurement of decay particles and reconstruction of secondary vertices will be possible. A two-track resolution of 2 cm at 2 m radial distance from, the interaction is expected. Momentum resolution of {Delta}p/p {approximately} 0.02 at p = 0.1 GeV/c is required to accomplish the physics, and,{Delta}p/p of several percent at p …

The significance of the low k{perpendicular} part of the Lipatov equation for the QCD soft Pomeron is discussed. It is then argued that light quarks are essential for the emergence of confinement and a Pomeron with the right physical properties. The implications for small {times} parton distributions are considered.

The objective of the work reported herein is to develop an understanding of the mechanical behavior of advanced ceramic composites subjected to elevated temperature and dynamic (cyclic) loading, to develop a test system and test methods to obtain the properties and performance information required to design engineering components made from ceramic composite materials, and to provide critical and comprehensive evaluations of such materials to material synthesizers and developers to support and enhance progress in ceramic composite material development. The accomplishments of the investigation include the design, development, and demonstration of a high temperature, biaxial mechanical test facility for ceramic composite tubes and the development and validation of a performance simulation model (MRLife) for ceramic composites.
