A literature survey was conducted to review the safety issues involved in handling hydrogen peroxide solutions. Most of the information found in the literature is not directly applicable to conditions at the Rocky Flats Plant, but one report describes experimental work conducted previously at Rocky Flats to determine decomposition reaction-rate constants for hydrogen peroxide solutions. Data from this report were used to calculate decomposition half-life times for hydrogen peroxide in solutions containing several decomposition catalysts. The information developed from this survey indicates that hydrogen peroxide will undergo both homogeneous and heterogeneous decomposition. The rate of decomposition is affected by temperature and the presence of catalytic agents. Decomposition of hydrogen peroxide is catalyzed by alkalies, strong acids, platinum group and transition metals, and dissolved salts of transition metals. Depending upon conditions, the consequence of a hydrogen peroxide decomposition can range from slow evolution of oxygen gas to a vapor, phase detonation of hydrogen peroxide vapors.

We report on amplification of 100 fsec laser pulses to 250 mJ using flashlamp-pumped, dye converted Ti:Sapphire. The resulting 5 Hz beam is focused to irradiances in excess of 5 {times} 10{sup 18} W/cm{sup 2}.

The operating principles of an Imaging Fourier Transform Spectrometer (IFTS) are discussed. The advantages and disadvantages of such instruments with respect to alternative imaging spectrometers are discussed. The primary advantages of the IFTS are the capacity to acquire more than an order of magnitude more spectral channels than alternative systems with more than an order of magnitude greater etendue than for alternative systems. The primary disadvantage of IFTS, or FTS in general, is the sensitivity to temporal fluctuations, either random or periodic. Data from the IRIFTS (ir IFTS) prototype instrument, sensitive in the infrared, are presented having a spectral sensitivity of 0.01 absorbance units, a spectral resolution of 6 cm{sup {minus}1} over the range 0 to 7899 cm{sup {minus}1}, and a spatial resolution of 2.5 mr.

Approximately 60 million gallons of high-level radioactive waste--caustic liquids, slurries, saltcakes, and sludges--are stored in underground tanks at the Department of Energy`s Hanford Site. At least one-third of the tanks are known to have leaked waste into the enviroranent, and there are many unresolved tank safety issues. In order to resolve the environmental and safety concerns, the Department plans to retrieve the waste, immobilize it, and dispose of it in a permanent geologic repository. Processing all of the tank waste in this manner could cost $40 billion, including $1.2 billion to construct the Hanford Waste Vitrification Plant. The purpose of our audit was to examine the reasons for cost estimate increases and schedule delays on the Hanford vitrification program. We also wanted to report on outstanding technical, safety, and environmental issues that could make the project even more costly and further delay its completion. We found that the Department managed the Hanford remediation system as a number of separate projects not fully integrated into one major system acquisition. Total costs have, therefore, been obscured, and the Department has not yet clearly defined system requirements or developed overall cost and schedule baselines. This lack of visibility could result in additional cost …

We have developed a system that allows compensation of higher order phase terms that limit chirped pulse amplification systems. Results indicate phase can be compensated by a properly adjusted air-spaced doublet within the stretcher.

The challenge of tuning an induction accelerator in real time has been addressed with the new TUNE GUIDE code. The code initializes a beam at a particular position using a tracer particle representation of the phase space. The particles are transported, using a matrix formulation, element by element along the beamline assuming that the field of a solenoid, or steering element is constant over its length. The other allowed elements are gaps and drift sections. A great deal of effort has been spent programming TUNE GUIDE to operate under the IBMPC Windows 3.1 system. This system features an intuitive, menu driven interface, which provides an ability to rapidly change beamline component parameter values. Consequently various accelerator setups can be explored and new values determined in real time while the accelerator is operating. In addition the code has the capability of varying a capability value over a range and then plotting the resulting beam properties, such as radius or centroid position, at a down stream position. Element parameter editing is also included along with an on-line hyper text oriented help package.

The Status of Glueballs is presented considering that most popular candidates from among the isoscalars in the J{sup PC} = 0{sup ++}, 0{sup {minus}+} and 2{sup ++} channels. It is shown that in the 0{sup ++} channel the f{sub 0}(1720) which was discovered earlier (the S*{prime}(1720)) at BNL is highly likely the same state as the SLAC {theta}(1720) now that its spin has been found to be 0 instead of the 2 claimed for a long period. In the {sup ++} channel there is likely a complex of 2-3 states {zeta}/{eta}(1280), {lambda}/{eta}(1420) and {iota}/{eta}(1520) involving at least one extra isosclar. In the 2{sup ++}, the g{sub T}(2010), g{sub T}{prime}(2300) and g{sub T}{double_prime}(2340) {phi}{phi} states found in {pi}{sup {minus}} p {yields} {phi}{phi}n (OZI forbidden glueball filter channel) strikingly, approximately, completely break the OZI suppression and comprise within the errors all the {phi}{phi} cross-section. The only viable explanation of these states in the context of QCD is that they are produced by 1-3 primary 2{sup ++} glueballs. All alternate explanations in the past 15 years have failed.

Lawrence Livermore National Laboratory (LLNL) is a US Department of Energy (DOE)` research and development (R&D) facility operated by the University of California. The R&D activities conducted at LLNL require the use of a wide variety of chemicals which are purchased in sufficient quantities to ensure that the necessary supply is on-hand to meet programmatic schedules and commitments. Purchasing control measures minimize excess inventories of unused chemicals, but small quantities of opened and unopened surplus chemicals still remain at the conclusion of research activities. Drum quantities of surplus chemicals also can be generated if a programmatic activity is abruptly terminated because of loss of funding. A real-time system was needed to route unused surplus chemicals to new experiments and programs instead of to waste treatment and disposal facilities. Representatives from four LLNL organizations (Lasers, Defense Systems/Nuclear Design, Chemistry, and Business Services) combined their skills and ideas to develop and implement an on-Ii ne surplus chemical exchange system for use at LLNL. An electronic surplus chemical bulletin board, referred to. as the ``LLNL Chemical Exchange Data Base,`` is the product of the group`s efforts.

The overall focus of this work was an attempt to better understand the nature of self attenuating particles of SNM for the purpose of developing procedures for correcting for particle self attenuation relative to improving the quantitative non-destructive assay of these materials. This report is a summary of the various schemes, calculations, data and data analysis performed relative to this subject.

A detailed technical plan for research on higher-alcohol synthesis in a slurry reactor was prepared and approved internally, as part of the University`s requirements for the doctoral degree. The focus of this plan is the high-pressure methanol synthesis catalyst, and modifications thereof. A major challenge of the research will be to identify a slurry medium that is stable at the typical operating temperature ofthis catalyst, i.e., about 400{degrees}C. Two shakedown runs were made in the stirred autoclave without catalyst in order to check the mechanical operation of the system and to test some of the analytical equipment. Further preparation, characterization and screening of higher-oxygenate synthesis catalysts based on rhodium were carried out. The catalyst compositions tested during the period were: Rh/Al{sub 2}O{sub 3}, Rh/Nb/Al{sub 2}O{sub 3}, Mo/Rh/Al{sub 2}O{sub 3} and W/Rh/Al{sub 2}O{sub 3}. All catalysts contained a nominal 1 wt. % Rh. Rh/Nb/Al{sub 2}O{sub 3} and Rh/Mo/Al{sub 2}O{sub 3} were about twice as active for COconversion as the other catalysts. However, oxygenate yields were disappointing for all of the compositions tested. The Rh/Mo/Al{sub 2}O{sub 3} catalyst had the highest carbon efficiency to oxygenates, 33%.
