We present details of a model for calculating the mass spectrum of light-quark mesons and decay constants of the pseudoscalar meson octet from a phenomenological model based on Dyson-Schwinger and Bethe-Salpeter equations. In this model the Bethe-Salpeter kernel is approximated by a separable ansatz obtained from input quark propagators. 13 refs., 2 tabs.

The present Report completes the investigations in the frame of the project for the first year. It is important to estimate our achievements in the investigation of properties of nanocrystalline materials obtained by severe plastic deformation and their production. We think that the main results obtained can be summarized as follows: (1) We performed an improvement of the die-set for equal channel (ECA) pressing and torsion under high pressure with the aim to increase dimensions of the samples produced and to conduct processing of low ductile materials. (2) It was established that in pure metals severe plastic deformation led to the formation of an ultra fine-grained structure with a mean grain size of 100-200 nm, while in alloys due to severe plastic deformation and/or special methods of treatment (a decrease in the temperature of deformation, an increase of the pressure applied etc.) the grain size could be decreased down to a few tens of manometers.

The theory of the reactive Robinson instability is formulated in terms of the terminal variables, its stopband structure is analysed, and the results are applied to the X-ray ring of the NSLS. The reactive Robinson instability for the case of multiple cavities in the storage ring is also studied.

The scientific base of magnetic fusion research comprises three capabilities: experimental research, theoretical understanding and computational modeling, with modeling providing the necessary link between the other two. The US now faces a budget climate that will preclude the construction of major new MFE facilities and limit MFE experimental operations. The situation is rather analogous to the one experienced by the DOE Defense Programs (DP), in which continued viability of the nuclear stockpile must be ensured despite the prohibition of underground experimental tests. DP is meeting this challenge, in part, by launching the Accelerated Strategic Computing Initiative (ASCI) to bring advanced algorithms and new hardware to bear on the problems of science-based stockpile stewardship (SBSS). ASCI has as its goal the establishment of a ``virtual testing`` capability, and it is expected to drive scientific software and hardware development through the next decade. The authors argue that a similar effort is warranted for the MFE program, that is, an initiative aimed at developing a comprehensive simulation capability for MFE, with the goal of enabling ``virtual experiments.`` It would play a role for MFE analogous to that played by present-day and future (ASCI) codes for nuclear weapons design and by LASNEX for ICF, …

This safety evaluation for packaging (SEP) provides the analysis and authorization to transport high-activity waste from the 324 Facility to PUREX, using the SEG 3-82B Type B cask. For the proposed campaign, the payload has larger quantities of radioactive material, is not fissile-exempt, and has higher decay heat loads than that specified by the 3-82B cask certificate of compliance. No changes will be made to the current design of the packaging. Onsite transport of the package with the higher source term will be authorized by this SEP to demonstrate equivalent safety of the package, as specified in PNL-MA-81, Hazardous Material Shipping Manual.

Objective is to demonstrate that a development program based on advanced reservoir management methods can significantly improve oil recovery and to transfer this technology to oil and gas producers in the Permian Basin. The demonstration plan includes developing a control area using standard reservoir management techniques and comparing the performance of the control area with an area developed using advanced management methods. Specific goals are (1) to demonstrate that a development drilling program and pressure maintenance program, based on advanced reservoir management methods, can significantly improve oil recovery compared with existing technology applications, and (2) to transfer the advanced technologies to oil and gas producers in the Permian Basin and elswhere in the US oil and gas industry. This is the first quarterly progress report on the project; results to date are summarized.

The work accomplished during the first six-month period of Phase II consisted of process laboratory experimentation and computer modeling of the process. Work on demonstration unit design and fabrication has awaited the results of these two tasks. Now that data are available from the laboratory phase, some of the design work can be initiated. The laboratory work has included equipment development, shakedown operations and actual process runs with the laboratory scale units. The computer modeling has been delayed by some logistical issues. Prof. Ruthven, project modeling consultant, moved from the University of New Brunswick to the University of Maine during the early stages of Phase II. He was still able to take delivery of Prof. Alpay`s gProm computer simulation package (from Imperial College in the UK) during that period, but was not able to make any runs with the system. The University of Maine`s Sun Workstations were not totally compatible with the gProm program. It has now been installed at the University of New Brunswick and Prof. Ruthven will be able to make simulation runs at that University. Results will-be available in the immediate future.

Title 1 of the Clean Air Act Amendment (CAAA) of 1990 requires NO{sub x} controls in ozone non- attainment areas. The initial Title 1 regulations, implemented over the last few years, required Reasonably Available Control Technologies (RACT). In most areas, the NO{sub x} levels for RACT are based on Low NO{sub x} Burners (LNB) and are in the range of 0.4 to 0.5 lb/10{sup 6} Btu. As a result, there has been little industry demand for higher efficiency and more expensive NO{sub x} controls such as reburning, Selective Non-Catalytic Reduction (SNCR), and Selective Catalytic Reduction (SCR). However, the current RACT requirements will not be the end of NO{sub x} regulations. Much more stringent NO{sub x} control will be required to bring many of the ozone non-attainment areas into compliance, particularly in the Northeast. This paper describes second generation advanced reburning for nitrogen oxides control.
