Audit of controls over Superconducting Super Collider Laboratory subcontractor expenditures (open access)

Audit of controls over Superconducting Super Collider Laboratory subcontractor expenditures

In January 1989 the Department of Energy contracted with Universities Research Association, Inc. to design, construct, manage, operate, and maintain the Superconducting Super Collider Laboratory. Through Fiscal Year 1992, costs for subcontractor goods and services accounted for about 75 percent of the Superconducting Super Collider Laboratory expenditures. The Office of Inspector General evaluated the adequacy of controls in place to ensure that subcontractor costs were reasonable, as required by the contract. The following conclusions were drawn from the audit. The Superconducting Super Collider Laboratory did not consistently exercise prudent business judgment in making subcontractor expenditures. As a result, $60 million in expenditures already made and $128 million planned with commercial subcontractors were, in the authors opinion, unnecessary, excessive, or represented uncontrolled growth. The audit also found inadequate justifications, accountability, and cost controls over $143 million in expenditures made and $47 million planned with other Department of Energy laboratories. Improvements were needed in subcontract administration and internal controls, including appropriate audit coverage of the subcontracts. In addition, Department of Energy guidance concerning procurement actions between the laboratories needed to be established.

Audit of economic development grants and a cooperative agreement with East Tennessee not-for-profit organizations (open access)

Audit of economic development grants and a cooperative agreement with East Tennessee not-for-profit organizations

As a result of the end of the Cold War, the Department of Energy (Department) has downsized many of its facilities. This may have a negative impact on many communities that were heavily dependent on Departmental operations for economic stability. To lessen the negative effects on these communities, the Department has encouraged the formation of community reuse organizations that are responsible for acting on behalf of the community to determine and sponsor initiatives to offset the consequences of the Department`s downsizing. One such initiative has been the award of economic development grants and cooperative agreements. The objective of the audit was to determine whether economic development grants and a cooperative agreement with East Tennessee not-for-profit organizations were achieving the Department`s intended purposes.

Beam-beam deflection and signature curves for elliptic beams (open access)

Beam-beam deflection and signature curves for elliptic beams

In this note we will present closed expressions for the beam-beam deflection angle for arbitrary elliptic beams including tilt. From these expressions signature curves, i.e., systematic deviations from the round beam deflection curve due to ellipticity or tilt are derived. In the course of the presentation we will prove that it is generally impossible to infer individual beam sizes from beam-beam deflection scans. 3 refs., 2 figs.

Coal reburning for cyclone boiler NO{sub x} control demonstration. Quarterly report No. 14, July--September 1993

The Coal Reburning for Cyclone Boiler NO{sub x} Control Demonstration project progress for July, August and September 1993 is identified in this 14th quarterly report and pertains to the activities on draft Final Report Preparation. The project involves retrofitting/testing the reburning technology at Wisconsin Power & Light`s 100 MW, Nelson Dewey Unit {number_sign}2 in Cassville, Wisconsin to determine the commercial applicability of this technology to reduce NO{sub x} emission levels. Phase III - Operation and Disposition activities emphasized preparation of the final report. A draft has been completed and it was provided to DOE/PETC in September for review and comment. The preliminary results of the hazardous air pollutant (HAP) testing indicate no major impact of reburn on volatile organics emissions. HAP results were completed and reported by Acurex in July, 1993.

Coarsening in Multicomponent Multiphase Systems [Final Report, November 1, 1995--October 31, 1998] (open access)

Coarsening in Multicomponent Multiphase Systems [Final Report, November 1, 1995--October 31, 1998]

The goal of the project was to extend the theory of particle coarsening, which is well established for binary systems, to the case of multicomponent and multiphase alloys. The theoretical approach involved three stages: (1) a mean field description based on the Lifshitz-Slyozov-Wagner (LSW) [1,2] formulation (recently published in Acta Mater. [3]), (2) an analytical description of coarsening valid at small volume fractions where the Marqusee and Ross [4] model was employed and (3) a numerical simulation of three phase coarsening where the boundary integral method of Akaiwa and Voorhees [5] was implemented. The main result of the mean field analysis can be stated as follows. The growth rate of a particle from a particular phase in a multiphase system is precisely the same as that derived for a single phase, multicomponent system. Also, it was found that the scaled particle size distribution for each phase in the system has exactly the same form as that originally derived by LSW. Since it neglects particle interactions, the mean field theory is clearly unrealistic and as such the formulation of coarsening in low volume fraction multiphase systems was undertaken.

CSER 97-008: 327 Building hot cell and SERF one-gallon can criticality analysis

This CSER gives the limits for the storage of one-gallon cans in the hot cells and the SERF in the 327 Building. The 327 Building is used to perform post irradiation testing of fissionable materials in remotely manipulated hot cells. Historically, scrap pieces of fuel cladding, cleanup materials, and other items have been placed into one-gallon paint cans for storage and ultimately disposal. These cans of materials had been assumed to contain no (or essentially no) fissionable materials, and therefore were not specifically controlled for material accountability. Recently, eight cans with high radiation levels were selected to be assayed for content. These cans contained from 0 to 2.5 grams of fissionable material, with an average of 1 gram per can. Since several of the hot cells contained a significant quantity of the cans, concerns were raised as to whether a CPS nonconformance had occurred, and should the cans have some limits for operation placed on them. This analysis is a response to the concerns raised, and gives guidance for incorporating operating limits for the one-gallon waste cans.

Design of 118 MHz twelfth harmonic cavity of APS PAR (open access)

Design of 118 MHz twelfth harmonic cavity of APS PAR

Two radio frequency (RF) cavities are needed in the Positron Accumulator Ring (PAR) of the Advanced Photon Source. One is for the first harmonic frequency at 9.8 MHz, and the other is for the twelfth harmonic frequency at 118 MHz. This note reports on the design of the 118 MHz RF cavity. Computer models are used to find the mode frequencies, impedances, Q-factors, and field distributions in the cavity. The computer codes MAFIA, URMEL, and URMEL-T are useful tools which model and simulate the resonance characteristics of a cavity. These codes employ the finite difference method to solve Maxwell`s equations. MAFIA is a three-dimensional problem solver and uses square patches to approximate the inner surface of a cavity. URMEL and URMEL-T are two-dimensional problem solvers and use rectangular and triangular meshes, respectively. URMEL-T and MAFIA can handle problems with arbitrary dielectric materials located inside the boundary. The cavity employs a circularly cylindrical ceramic window to limit the vacuum to the beam pipe. The ceramic window used in the modeling will have a wall thickness of 0.9 cm. This wall thickness is not negligible in determining the resonant frequencies of the cavity. In the following, results of two- and three-dimensional modeling …

Development of a video-based slurry sensor for on-line ash analysis. Eighth quarterly technical progress report, July 1, 1996--September 30, 1996 (open access)

Development of a video-based slurry sensor for on-line ash analysis. Eighth quarterly technical progress report, July 1, 1996--September 30, 1996

Automatic control of fine coal cleaning circuits has traditionally been limited by the lack of sensors for on-line ash analysis. Although several nuclear-based analyzers are available, none have seen widespread acceptance. This is largely due to the fact that nuclear sensors are expensive and tend to be influenced by changes in seam type and pyrite content. Recently, researchers at VPI&SU have developed an optical sensor for phosphate analysis. The sensor uses image processing technology to analyze video images of phosphate ore. It is currently being used by PCS Phosphate for off-fine analysis of dry flotation concentrate. The primary advantages of optical sensors over nuclear sensors are that they are significantly cheaper, are not subject to measurement variations due to changes in high atomic number minerals, are inherently safer and require no special radiation permitting. The purpose of this work is to apply the knowledge gained in the development of an optical phosphate analyzer to the development of an on-fine ash analyzer for fine coal slurries. During the past quarter, installation of the video-based ash analyzer at the Middle Fork plant site was completed. A method of measuring and automatically adjusting for small variations in the sensor illumination scheme was developed …

Dispersion calculations for non-radiological hazardous chemical emissions from the Defense Waste Processing Facility and related activities (open access)

Dispersion calculations for non-radiological hazardous chemical emissions from the Defense Waste Processing Facility and related activities

The Environmental Protection Agency's (EPA) Industrial Source Complex -- Short Term (ISCST) air dispersion model was used to examine potential atmospheric impacts of routine benzene and mercury emissions from the Defense Waste Processing Facility (DWPF), In-Tank Precipitation (ITP) facilities, and the Saltstone Facility. The highest model estimated 8-hour average ground-level benzene concentrations were found to occur in the immediate vicinity of the ITP filter/stripper building (241-96H). Subsequent model calculations were used to determine minimum stack release heights that would be necessary to achieve compliance with this workplace exposure standard for currently anticipated emission levels. The highest 24-hour average site boundary concentrations of benzene and mercury generally occurred to the north of S and H areas. Concentrations were well below the ambient concentration standards that have been identified for these substances in an air toxics policy proposed by the State of South Carolina. Estimates of annual average benzene concentrations for offsite locations were used to estimate the excess lifetime cancer risk. Assuming continuous 70-year exposure to the estimated annual benzene concentrations, the excess cancer risk to the maximum exposed individual was estimated to be 3 {times} 10{sup {minus}7}. Similar lifetime exposure summed over the surrounding population resulted in an estimated average …

Effect of Pb and air absorber thickness on [sup 137]Cs signal

We present the results of a measurement to understand the effects of transverse misplacement of the [sup 137]Cs source tube inside the cast Pb plates of the SDC EMC calorimeter. The PMT current from a scintillator was measured as the [sup 137]Cs source was displaced by varying thicknesses of Pb, as well as varying thicknesses of air gap. At a nominal depth of 2 mm in Pb, we find a change in scintillator output of about 25%/mm, and about 10%/mm of air gap. The data are compared to a simple calculation. By taking the sum of the scintillators on top and below a source tube, we estimate a source tube displacement of [plus minus]450[mu] will cause an error in the PMT output by 1%.

The effects of 450 kg surface explosions at the E layer of the ionosphere. Los Alamos Source Region Project

A network of hf ionospheric sounders consisting of two transmitter and two receiver stations was deployed to detect the effects of acoustic waves generated by surface ground motion following an underground nuclear test (UGT) at the Nevada Test Site. The frequency of the transmissions were chosen so that the hf radio waves were totally reflected in the E layer of the ionosphere at an altitude of approximately 100 km. The transmissions were highly stable cw tones at two frequencies separated by 100 kHz so that two altitudes separated by approximately .5 km could be sensed. The network sampled four geographic locations in the ionosphere ranging from almost directly overhead of the UGT out to a horizontal range of 60 km. The ionospheric sounders detected disturbances on all the paths beginning at approximately 325 s after the UGT which persisted for up to 100 s. These disturbances will be described in detail in a later paper. Shortly after the UGT an extended series of ionospheric disturbances were detected which we ascribe to the arrival of acoustic shock waves at the E layer caused by the surface detonation of ordinance with effective yields of 450 kg of high explosive during an unrelated …

(Environmental impact of radionuclide release during the Kyshtym, Windscale, and Chernobyl accidents)

The traveler attended the conference, Comparative Assessment of the Environmental Impact of Radionuclides Released During Three Major Nuclear Accidents: Kyshtym, Windscale, and Chernobyl and presented an invited paper giving a western perspective of the Kyshtym (Chelyabinsk-40) high-level waste explosion that took place in 1957. Papers of interest to several ORNL and DOE programs were presented. These covered the topics of accident source terms, atmospheric dispersion, resuspension, chemical and physical forms of contamination (e.g., hot'' particles), environmental contamination and transfer, radiological effects on humans and the environment, and countermeasures. The traveler also made valuable contacts with Soviet and other scientists related to an ongoing assessment sponsored by the International Union of Radioecologists of releases from the Chelyabinsk-40 site. This included an agreement in principle for direct participation by key Soviet scientists.

Environmental Protection Agency: FY2000 Budget Issues

State and local wastewater and drinking water capital needs were the most prominent budgetary issues. Senate and House authorizing and appropriating chairmen expressed concern over the requested 17% decrease in the State and Tribal Assistance Grants account from $3.41 billion in FY1999 to $2.84 billion in FY2000. The conference agreement on H.R. 2684 provides a total of $3.47 billion. For clean water state revolving funds, the conference committee approved the Senate's level of $1.35 billion, about $175 million more than the House approved and roughly $550 million more than requested. The conference agreement included $332 million for special project grants, about $73 million more than the House's proposal, roughly $232 million more than the Senate approved, and about $304 million more than requested. For drinking water state revolving funds, the conference committee approved $820 million, $45 million more than the House's amount and $5 million less than the Senate approved and the President requested. The conference committee also approved the Administration's request of $885 million for state and tribal administrative grants, which is roughly the same as the amount enacted for FY1999.

An evaluation of foaming potential in the IDMS melter

The present DWPF flowsheet calls for the chemical treatment of waste sludge with 90 wt% formic acid prior to the addition of the Precipitate Hydrolysis Aqueous (PHA) product. An alternative processing methodology, denoted the ``Nitric Acid Flowsheet``, has been proposed. In the application of this flowsheet, nitric acid would be used to neutralize sludge base components (hydroxides and carbonates) prior to the addition of late wash PHA. The late wash PHA will contain sufficient quantities of formic acid to adequately complete necessary reduction-oxidation (REDOX) reactions. The use of this flowsheet may result in a change in the nominal concentrations of two of the major REDOX reaction participants: formate (HCOO{sup minus}) and nitrate (NO{sub 3}{sup minus}).
