Due to the relocation of a magnet power supply, the installation of a buss, and an installation of chokes. and their need for cooling water a redesign of the Low Conductivity Water (LCW) system has been undertaken. This new system required the determination of an optimal pipe diameter for the High Bay pipe as well as the determination of the pressure drop and temperature rise in the buss. Based on numerous calculations it has been determined that the High Bay pipe should be 1 1/2 inch (1.90 O.D. x 1.610 I.D-40S steel). While the pressure drop in the buss was calculated to be 7.699 psi. Based on such a low pressure drop, no need for any additional pumps has presented itself. Finally, the temperature rise in the buss has been determined to be about 29.39 F for the Assembly Hall (route No.1). and 13.93 F for the Collision Hall (route No.2). The purpose of this engineering note is to explain the redesign of the low conductivity water system (LCW) at D-Zero. The areas to be covered include the sizing of the High Bay, the pressure drop and temperature rise in the buss. In addition, I will try to determine if …

In December 1992, the US Department of Energy (DOE) directed that the Plutonium-Uranium Extraction (PUREX) Plant be shut down and deactivated because it was no longer needed to support the nation`s production of weapons-grade plutonium. The PUREX/UO{sub 2} Deactivation Project will establish a safe and environmentally secure configuration for the facility and preserve that configuration for 10 years. The 10-year span is used to predict future maintenance requirements and represents the estimated time needed to define, authorize, and initiate the follow-on decontamination and decommissioning activities. Accomplishing the deactivation project involves many activities. Removing major hazards, such as excess chemicals, spent fuel, and residual plutonium are major goals of the project. The scope of the PUREX Transition Project is described within.

This safety assessment (SA) addresses each of the required elements associated with the installation, operation, and removal of a rotary-mode core sampling (RMCS) device in flammable-gas single-shell tanks (SSTs). The RMCS operations are needed in order to retrieve waste samples from SSTs with hard layers of waste for which push-mode sampling is not adequate for sampling. In this SA, potential hazards associated with the proposed action were identified and evaluated systematically. Several potential accident cases that could result in radiological or toxicological gas releases were identified and analyzed and their consequences assessed. Administrative controls, procedures and design changes required to eliminate or reduce the potential of hazards were identified. The accidents were analyzed under nine categories, four of which were burn scenarios. In SSTS, burn accidents result in unacceptable consequences because of a potential dome collapse. The accidents in which an aboveground burn propagates into the dome space were shown to be in the ``beyond extremely unlikely`` frequency category. Given the unknown nature of the gas-release behavior in the SSTS, a number of design changes and administrative controls were implemented to achieve these low frequencies. Likewise, drill string fires and dome space fires were shown to be very low frequency …

This analysis is prepared by the Mined Geologic Disposal System (MGDS) Waste Package Development Department (WPDD) to compare the criticality potential of Westinghouse 17 x 17 mixed oxide (MOX) PWR fuel with the Design Basis spent nuclear fuel (SNF) analyzed previously (Ref. 5.1, 5.2). The basis of comparison will be the conceptual design Multi-Purpose Canister (MPC) PWR waste package concepts. The objectives of this evaluation are to show that the criticality potential of the MOX fuel is equal to or lower than the DBF or, if necessary, indicate what additional measures are required to make it so.

The purpose of this analysis is to define the spatial requirements of the area (pad) for storage of muck removed from the tunnel area during the construction of the Exploratory Studies Facility (ESF). This analysis uses the estimate for the amount of material to be removed and determines the required area of the storage pad. Two different areas, Areas 1 and 2, considered as primarily suitable areas, will be analyzed (see Attachment I). An Optional Muck Storage Area, to be located to the east of the ESF pad, will also be analyzed for available volume, with an option of raising the stockpile of muck to 49 feet (see Attachments II and III).

Salary information was collected for July 1996 for personnel working as nuclear engineers and health physicists. The salary information includes personnel at the B.S., M.S., and Ph.D. levels with zero, one, three, four to seven, and eight to ten years of professional work experience. Information is provided for utilities and non-utilities. Non-utilities include private sector organizations and U.S. Department of Energy contractor-operated facilities. Government agencies, the military, academic organizations, and medical facilities are excluded. In previous years the salary data have been collected for October. In 1996, the data were collected for July; thus, some caution must be exercised in making annual salary trend comparisons.

The purpose of this engineering note is to explain the method involved in calculating the mass flow rates through venturis and orifice plates at sub-sonic conditions. In particular, the mass flow rate calculations are required for two FLOW-DYNE venturi flow meters, serial no. 35821 and no. 35822, and an orifice plate flow meter, serial no. 35823. The two venturis, FT-4052-H and FT-4053-H, are located in the D-Zero VLPC valve box at the refrigerator and the orifice plate, FO-2019-H, is on the high pressure helium supply line in the assembly building.

The new camera FXI was investigated. Spatial resolution, or its Fourier transform, the modulation transfer function (MTF), is critical for quantitative interpretation of recent hydrodynamic instability data taken on the Nova laser. We have taken data corresponding to backlit straight edges, pinholes, and grids, both on the bench and {ital in}{ital situ} on Nova. For both the pinhole and edge data, the MTF at all wavelengths of interest can be deduced from a single image. Grids are of more limited usefulness, giving the MTF value only at the spatial period of the grid. These different techniques for characterizing the MTF of gated x-ray pinhole cameras are discussed, with results specific to the FXI presented.

Currently, the Morgantown Energy Technology Center, is actively investigating alternative hot fuel gas desulfurization sorbents for application to the Integrated Gasification Combined Cycle (IGCC). A sorbent must be highly active towards sulfur at high temperatures and pressure`s, and under varying degrees of reducing atmospheres. Thus, high conversion of the metal oxide and low hydrogen sulfide exit partial pressures. Also, it must regenerate nearly ideally to maintain activity over numerous cycles. Furthermore, regeneration must yield a sulfur product which is economically recoverable directly or indirectly. This cyclic process requires a holistic approach as any one criteria may eliminate a candidate sorbent from further consideration. Over fifty induration campaigns have been conducted among the fifteens Mn-based sorbent formulations. All indurated sorbents has been tested for crush strength and chemical analysis. Also, fifteen sorbent formulations have been tested in a TGA for at least on e induration condition. Subsequently described are the three main groups of formulations tested. They are the MnCO{sub 3} supported with TiO{sub 2} (with or without bentonite), MnCO{sub 3} supported with Al{sub 2}O{sub 3} (with or without porosity enhancers), and MnO{sub 2} ore supported with alundum (with and without bentonite).

The specific goals of the ASTC program were: to pilot and administer a year round program to engage and support ethnic minority and women students to enter the pre-college teaching profession; and to develop the ASTC program across California on all twenty CSU campuses. The initial goal of piloting a year round program to engage and support ethnic or underrepresented science students to enter the teaching profession was put in place at CSUS in the Fall of 1993, with the recruitment of students to enter the program in the Spring of 1993. Three students were selected to enter the program, one male Latino, one female Latina and one Caucasian female. The areas of study of these students was respectively biology, physics and geology. All of the students were within two years or less of completing their degree requirements. During the first semester of the program the authors worked on the portion of the model dealing with student participation in the schools with a mentor teacher. The idea being the students would spend a minimum of six hours a week in the classroom of the mentor teacher working with them and their students. In addition the students were assigned to a …

Each of the twelve Booster Main Magnet Power Supply modules consist of two three-phase, full-wave rectifier bridges in series to provide a 560 VDC maximum output. The harmonic contents of the twelve-pulse ac-dc converter output are multiples of the 60 Hz ac power input, with a predominant 720 Hz signal greater than 14 dB in magnitude above the closest harmonic components at maximum output. The 720 Hz harmonic is typically greater than 20 dB below the 500 VDC output signal under normal operation. Extracting specific harmonics from the rectifier output signal of a 6, 12, or 24 pulse ac-dc converter allows the detection of SCR firing angle errors or complete misfires. A bandpass filter provides the input signal to a frequency-to-voltage converter. Comparing the output of the frequency-to-voltage converter to a reference voltage level provides an indication of the magnitude of the harmonics in the ac-dc converter output signal.

Solar is developing the technologies for a highly efficient, recuperated, Advanced Turbine System (ATS) that is aimed at the dispersed power generation market. With ultra-low-emissions in mind the primary fuel selected for this engine system is natural gas. Although this gas fired ATS (GFATS) will primarily employ natural gas the use of other fuels particular those derived from coal and renewable resources cannot be overlooked. The enabling technologies necessary to direct fire coal in gas turbines were developed during the 1980`s. This Solar development co-sponsored by the US Department of Energy (DOE) resulted in the testing of a full size coal-water-slurry fired combustion system. In parallel with this program the DOE funded the development of integrated gasification combined cycle systems (IGCC). This report describes the limitations of the Solar ATs (recuperated engine) and how these lead to a recommended series of modifications that will allow the use of these alternate fuels. Three approaches have been considered: direct-fired combustion using either a slagging combustor, or a pressurized fluidized bed (PFBC), externally or indirectly fired approaches using pulverized fuel, and external gasification of the fuel with subsequent direct combustion of the secondary fuel. Each of these approaches requires substantial hardware and system …
