Civilian Power Reactor Program. Part II. Economic Potential and Development Program. Heavy Water-Moderated Power Reactor (open access)

Civilian Power Reactor Program. Part II. Economic Potential and Development Program. Heavy Water-Moderated Power Reactor

The reactor design which forms the base for the current economic status of D/sub 2/O-moderated reactors was estimated from developments in several reactor programs. However, since a heavy water-moderated reactor was not operated on natural U fuel at power reactor conditions, considerable improvement from this current status can be foreseen. A summary of improvements is presented concerning the concept which would result solely from operation of succeeding generation plants without a parallel development program, and improvements which would result from the successful completion of the development program as presented. One plant size was used in the evaluation of plant potential, with a 300 Mw/sub e/ nominal rating. The boiling D/sub 2/O-cooled, pressure tube direct cycle plant design was used. The current development program is outlined; this work includes several items leading to the long-range development of the concept. (auth)

Civilian Power Reactor Program. Part III. Status Report on Large (100 and 300 MWe) Heavy Water-Moderated Power Reactors--as of 1960 (open access)

Civilian Power Reactor Program. Part III. Status Report on Large (100 and 300 MWe) Heavy Water-Moderated Power Reactors--as of 1960

An evaluation of 300- and 100-Mwe power plants was conducted using ground rules prescribed by the USAEC for this study. Costs corresponding to two average discharged fuel burnups are: 8.6 mills/kwh (8500 Mwd/ metric ton) and 8.8 mills/kwh (7500 Mwd/metric ton) for the 300-Mw plant. Costs for the 100 Mw plant are 14.7 mills/kwh for an average discharged fuel burnup of 6010 Mwd/metric ton. Estimates of future potential indicate that the 300 Mw/sub 3/ (8500 Mwd/metric ton) plant could produce power for 7.3 mills/kwh in a second generation, full scale plant of the same type. A further reduction to 6.4 mills/kwh should be possible as the result of the recommended ten-year development program. The current development program is adequate for providing the data needed to design and construct a prototype reactor. However, there is no natural U-fueled prototype and no prototype of the chosen reference design scheduled in the U.S. Current technology is sufficiently developed to initiate the design and construction of a pressure tube, boiling D/sub 2/Ocooled, natural UO/sub 2/- fueled reactor prototype plant in the immediate future. This plant would demonstrate the main features of a full scale plant and, in addition. would provide design data which could …

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent (open access)

Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-scale, fixed-bed reactor. Durability may be defined as the ability of the sorbent to maintain important physical characteristics such As size, strength, and specific surface area during 10 cycles of sulfidation and oxidation.

Child Care: Overview of Relevant Employment Laws and Cases of Sex Offenders at Child Care Facilities

A letter report issued by the Government Accountability Office with an abstract that begins "Very little is known about sexual abuse among children that are regularly cared for by more than 1.3 million child care providers every week in the United States. In this context, GAO was asked to (1) provide an overview of federal and state laws related to the employment of sex offenders at child care facilities and (2) examine cases where individuals who were convicted of serious sexual offenses were subsequently employed or present at child care facilities. To provide an overview of selected laws, GAO searched for prohibitions against offenders being present at child care facilities, requirements for conducting criminal-history checks, and penalties for violating these requirements. The cases GAO examined focus only on individuals who were convicted of serious sexual offenses and cannot be generalized to all child care facilities. To identify the cases, GAO reviewed open-source information from 2000 to 2010. GAO also compared the years 2007 to 2009 in employment databases from 20 states and the District of Columbia to data in the National Sex Offender Registry. GAO ultimately selected 10 cases from eight states and the District of Columbia for review. For …

Welfare Reform: HHS Should Exercise Oversight to Help Ensure TANF Work Participation Is Measured Consistently across States

A letter report issued by the Government Accountability Office with an abstract that begins "The debate over reauthorization of the Temporary Assistance for Needy Families (TANF) block grant has focused on work requirements and brought attention to the measure of TANF work participation. The measure is used to assess states' performance and determine whether a state is subject to penalty for not meeting TANF work requirements. The 2003 work participation rates ranged from 9 to 88 percent for the 50 states based on data they submit to the U.S. Department of Health and Human Services (HHS). To help Congress understand these rates, GAO looked at (1) how selected states are defining the categories of work activities, (2) whether selected states have implemented internal controls over the work participation data, and (3) what guidance and oversight HHS has provided states."

A letter report issued by the General Accounting Office with an abstract that begins "The federal government has many vacant and underutilized properties that are no longer needed. Retaining unneeded real properties presents federal agencies with significant potential risks for (1) lost dollars because such properties are costly to maintain; and (2) lost opportunities because the properties could be put to more cost-beneficial uses, exchanged for other needed property, or sold to generate revenue for the government. The General Services Administration (GSA), the Department of Veterans Affairs (VA), and the U.S. Postal Service (USPS) hold a significant number of real property assets. GAO was asked to provide information on how these agencies identify vacant and underutilized real properties and the numbers, types, and locations of these properties."

Effects of Plasma Shaping on Nonlinear Gyrokinetic Turbulence (open access)

Effects of Plasma Shaping on Nonlinear Gyrokinetic Turbulence

The effects of flux surface shape on the gyrokinetic stability and transport of tokamak plasmas are studied using the GS2 code [M. Kotschenreuther, G. Rewoldt, and W.M. Tang, Comput. Phys. Commun. 88, 128 (1995); W. Dorland, F. Jenko, M. Kotschenreuther, and B.N. Rogers, Phys. Rev. Lett. 85, 5579 (2000)]. Studies of the scaling of nonlinear turbulence with shaping parameters are performed using analytic equilibria based on interpolations of representative shapes of the Joint European Torus (JET) [P.H. Rebut and B.E. Keen, Fusion Technol. 11, 13 (1987)]. High shaping is found to be a stabilizing influence on both the linear ion-temperature-gradient (ITG) instability and the nonlinear ITG turbulence. For the parameter regime studied here, a scaling of the heat flux with elongation of χ ∼ ℵ-1.5 or ℵ-2.0, depending on the triangularity, is observed at fixed average temperature gradient. While this is not as strong as empirical elongation scalings, it is also found that high shaping results in a larger Dimits upshift of the nonlinear critical temperature gradient due to an enhancement of the Rosenbluth-Hinton residual zonal flows.

EVALUATION OF SULFATE ATTACK ON SALTSTONE VAULT CONCRETE AND SALTSTONESIMCO TECHNOLOGIES, INC. PART1 FINAL REPORT

This report summarizes the preliminary results of a durability analysis performed by SIMCO Technologies Inc. to assess the effects of contacting saltstone Vaults 1/4 and Disposal Unit 2 concretes with highly alkaline solutions containing high concentrations of dissolved sulfate. The STADIUM{reg_sign} code and data from two surrogate concretes which are similar to the Vaults 1/4 and Disposal Unit 2 concretes were used in the preliminary durability analysis. Simulation results for these surrogate concrete mixes are provided in this report. The STADIUM{reg_sign} code will be re-run using transport properties measured for the SRS Vaults 1/4 and Disposal Unit 2 concrete samples after SIMCO personnel complete characterization testing on samples of these materials. Simulation results which utilize properties measured for samples of Vaults 1/4 and Disposal Unit 2 concretes will be provided in Revision 1 of this report after property data become available. The modeling performed to date provided the following information on two concrete mixes that will be used to support the Saltstone PA: (1) Relationship between the rate of advancement of the sulfate front (depth of sulfate ion penetration into the concrete) and the rate of change of the concrete permeability and diffusivity. (2) Relationship between the sulfate ion concentration …

Failure analysis of Ti - 15% Ta getter wire used for sublimation in the vacuum chambers of the Tandem Mirror Experiment (open access)

Failure analysis of Ti - 15% Ta getter wire used for sublimation in the vacuum chambers of the Tandem Mirror Experiment

The Tandem Mirror Experiment uses Ti-15% Ta getter wire for sublimation in the vacuum chambers in which the magnets are located. These wires have failed prematurely in service, resulting in increased costs and downtime. We have used optical metallography to show that the reason for these failures was the cycling of the material through the alpha-beta transition temperature, causing alpha-titanium precipitation at the grain boundaries, depression of the melting temperatures of those boundaries, and the subsequent melting of those boundaries in areas where the wires had achieved localized higher temperatures.

Uranium-232 production in current design LWRs (open access)

Uranium-232 production in current design LWRs

The spectrum-dependent zero dimensional depletion code, LEOPARD, was modified to permit a study of uranium-232 buildup in pressurized (PWR) and boiling water reactors (BWR). The results of the study showed good agreement with comparable calculations performed by Westinghouse for PWRs but poor agreement with General Electric calculations for BWRs. Differences noted were attributed to the nuclear cross section data and, in the case of the BWR results, the method of calculation. This study indicates that even at the high burnups projected for current light water reactor fuels, the discharged fuels do not reach concentrations of U-232 in excess of the current gaseous diffusion plant feed specification of 110 ppB (U-232/U-235) provided the fuel charged to the reactor is free of thorium and U-236 and that the reactor achieves a reasonable load factor. However, the U-232 concentration in reactor fuel increases between the time it is discharged from the reactor and the time it is reprocessed. After about two years of storage the U-232 concentration reaches the 110 ppB limit. The following conditions were shown to cause the U-232 concentration in reactor fuel at discharge to exceed the current GDP feed specification: a fuel loading with in excess of 88 ppB …
