We wish to calculate the Lorentz body force associated with pure multipole helical magnetic fields (i.e, proportional to cos(n{theta})) whose strength varies purely as a Fourier sinusoidal series of the longitudinal coordinate z (say proportional to cos(2m-1){pi}z)/L, where L denotes the half-period of the wiggler field and m= 1,2,3... We also wish to apply such forces to the current sheet, and solve for the stress distribution required to maintain such a coil in equilibrium. In the calculations of Lorentz forces we include the self field contribution as well as possible contributions arising from additional nested helical windings. We shall demonstrate that in cases where the current is situated on a surface of discontinuity at r=R (i.e. J=f({theta},z)) and the Lorentz body force is integrated on that surface, a closed form solution for the stress distribution can be obtained and such a solution includes contributions from possible nested multi pole magnets. Finally we demonstrate that in the limiting 2D case where the field strength does not vary with z ( period 2L tends to infinity) the stress reduces to known 2D expressions.

Seismic responses of the Zion nuclear power generation complex accounting for structure-to-structure interaction effects as predicted by CLASSI and FLUSH Codes are presented in this paper. Two aspects of the multi-structure analyses were considered: the effect of structure-to-structure interaction on structure response and the variability in structure response as predicted by different codes, including structure-to-structure interaction. The effect of structure- to-structure interaction on the response of the Zion reactor building and AFT complex (the auxiliary/fuel-handling/turbine building complex) was assessed by comparing the results of CLASSI analyses with and without interaction between structures. The results show that the reactor building has a very small effect on the AFT complex, but the effect of structure-to-structure interaction on the reactor building from the AFT complex is substantial. A comparison of the reactor building`s response as predicted by CLASSI and FLUSH, structures including structure-to-structure interaction, shows significant differences. Modeling three-dimensional configuration of a complicated power plant structure such as the Zion`s with equivalent two-dimensional models for structure-to-structure interaction analysis requires careful consideration.

Specification requirements for engineering, fabrication, and performance of cone penetrometer (CP) soil multisensor and sampling probes (CP-probes) which are required to support contract procurement for services are presented. The specification provides a documented technical basis of quality assurance that is required to use the probes in an operating Hanford tank farm. The documentation cited in this specification will be incorporated into an operational fielding plan that will address all activities associated with the use of the CP-probes. The probes discussed in this specification support the Hanford Tanks Initiative AX-104 Tank Plume Characterization Sub-task. The probes will be used to interrogate soils and vadose zone surrounding tank AX-104.

A major function of the Tank Waste Remediation System (TWRS) is to characterize wastes in support of waste management and disposal activities at the Hanford Site. Analytical data from sampling and analysis, along with other available information about a tank, are compiled and maintained in a tank characterization report (TCR). This report and its appendixes serve as the TCR for double-shell tank 241-AN-105. The objectives of this report are: (1) to use characterization data in response to technical issues associated with tank 241-AN-105 waste; and (2) to provide a standard characterization of this waste in terms of a best-basis inventory estimate. The response to technical issues is summarized in Section 2.0, and the best-basis inventory estimate is presented in Section 3.0. Recommendations regarding safety status and additional sampling needs are provided in Section 4.0. Supporting data and information are contained in the appendices. This report also supports the requirements of the Hanford Federal Facility Agreement and Consent Order (Ecology et al. 1996) milestone M-44-10.

This document is the final laboratory report for Tank 241-BY-111. Push mode core segments were removed from risers 15 and 12A between August 13, 1996, and September 3, 1996. Segments were received and extruded at 222-S Laboratory. Analyses were performed in accordance with Tank 241-BY-111 Rotary Mode Core Sampling and Analysis Plan (TSAP) (Kruger, 1996) and Safety Screening Data Quality Objective (DQO) (Dukelow, et al., 1995). None of the subsamples submitted for total alpha activity (AT) or differential scanning calorimetry (DSC) analyses exceeded the notification limits stated in DQO. Two cores of nine segments were expected from this tank. Sampling problems prevented the acquisition of complete cores. Attachment 1 illustrates subsamples generated in the laboratory for analysis and identifies their sources. This reference also relates tank farm identification numbers to their corresponding 222-S Laboratory Information Management System (LIMS) sample numbers.

This document contains review comment records for the CVDF 90% design review. Spent fuels retrieved from the K Basins will be dried at the CVDF. It has also been recommended that the Multi-Conister Overpacks be welded, inspected, and repaired at the CVD Facility before transport to dry storage.

This report contains tables of the analytical results from sampling Tank 241-A-101 for the following: fluorides, chlorides, nitrites, bromides, nitrates, phosphates, sulfates, and oxalates. This tank is listed on the Hydrogen Watch List.

A root-mean-square (rms) phase gradient specification seems to allow a good connection between the NIP optics quality and focal spot requirements. Measurements on Beamlet optics individually, and as a chain, indicate they meet the assumptions necessary to use this specification, and that they have a typical rms phase gradient of {approximately}80 {angstrom}/cm. This may be sufficient for NIP to meet the proposed Stockpile Stewardship Management Program (SSMP) requirements of 80% of a high- power beam within a 200-250 micron diameter spot. Uncertainties include, especially, the scale length of the optics phase noise, the ability of the adaptive optic to correct against pump-induced distortions and optics noise, and the possibility of finding mitigation techniques against whole-beam self-focusing (e.g. a pre- correction optic). Further work is needed in these areas to better determine the NIF specifications. This memo is a written summary of a presentation on this topic given by W. Williams 24 April 1997 to NIP and LS&T personnel.

The Department of Energy`s (Department) network of management and operating contractors, as well as other prime contractors, procure over $270 million in goods and services from each other on a yearly basis by using intra-Departmental requisitions. The objective of the audit was to determine whether intra-Departmental requisitions were used appropriately. Specifically, that they were not used to (1) obtain commercially available goods and services; (2) acquire services outside the performing contractor`s mission; (3) procure the services of subcontractors; and (4) augment staffing. The audit disclosed that the Department`s prime contractors did not use intra-Departmental requisitions appropriately for 40 of the 104 requisitions reviewed. As a result, the Department did not always receive the most cost effective goods and services. For example, on two requisitions the Department could have saved almost $850,000 out of $1.6 million if the prime contractors had used normal procurement channels and competed the acquisitions. In other instances, using intra-Departmental requisitions resulted in multiple overhead rates being added to the cost of the goods or services procured. We recommended the Department issue criteria on the use of intra-Departmental requisitions. We also recommended operations offices establish policies and procedures over the use of these requisitions and provide a …

Research Triangle Institute (RTI), Eastman Chemical Company, and Bechtel collectively are developing a novel process for the synthesis of methyl methacrylate (MMA) from coal-derived syngas, under a contract from the US Department of Energy, Federal Energy Technology Center. This three-step process consists of synthesis of a propionate, its condensation with formaldehyde, and esterification of resulting methacrylic acid (MAA) with methanol to produce MMA. Eastman has focused on the propionate synthesis step. the resultant Mo catalysts work efficiently at much less severe conditions (170{degrees}C and 30 atm) than the conventional Ni catalysts (270{degrees}C and 180 atm). Bechtel has performed an extensive cost analysis which shows that Eastman`s propionate synthesis step is competitive with other technologies to produce the anhydride. In the second step, RTI and Eastman have developed active and stable V-Si-P ternary metal oxide catalysts Nb/SiO{sub 2} and Ta/SiO{sub 2} catalysts for the condensation of propionic anhydride and acid with formaldehyde. RTI has demonstrated a novel correlation among the catalyst acid-base properties, condensation reaction yield, and long-term catalyst activity. Current research focuses on enhancing the condensation reaction yields by better understanding of the acid-base property correlation, in situ condensation in a high-temperature, high- pressure (HTHP) slurry reactor, and alternate formaldehyde …
