Using Condition Monitoring to Predict Remaining Life of Electric Cables
Electric cables are passive components used extensively throughout nuclear power stations to perform numerous safety and non-safety functions. It is known that the polymers commonly used to insulate the conductors on these cables can degrade with time; the rate of degradation being dependent on the severity of the conditions in which the cables operate. Cables do not receive routine maintenance and, since it can be very costly, they are not replaced on a regular basis. Therefore, to ensure their continued functional performance, it would be beneficial if condition monitoring techniques could be used to estimate the remaining useful life of these components. A great deal of research has been performed on various condition monitoring techniques for use on electric cables. In a research program sponsored by the U.S. Nuclear Regulatory Commission, several promising techniques were evaluated and found to provide trendable information on the condition of low-voltage electric cables. These techniques may be useful for predicting remaining life if well defined limiting values for the aging properties being measured can be determined. However, each technique has advantages and limitations that must be addressed in order to use it effectively, and the necessary limiting values are not always easy to obtain. …

WATER AS A REAGENT FOR SOIL REMEDIATION
SRI International is conducting experiments to develop and evaluate hydrothermal extraction technology or hot water extraction (HWE) technology for remediating petroleum-contaminated soils. Most current remediation practices either fail to remove the polycyclic aromatic hydrocarbons (PAHs) found in petroleum-contaminated sites, are too costly, or require the use of organic solvents at the expense of additional contamination and with the added cost of recycling solvents. Hydrothermal extraction offers the promise of efficiently extracting PAHs and other kinds of organics from contaminated soils at moderate temperatures and pressures, using only water and inorganic salts such as carbonate. SRI has conducted experiments to measure the solubility and rate of solubilization of selected PAHs (fluoranthene, pyrene, chrysene, 9,10-dimethylanthracene) in water using SRI's hydrothermal optical cell with the addition of varying amounts of sodium carbonate to evaluate the efficiency of the technology for removing PAHs from the soil. SRI data shows a very rapid increase in solubility of PAHs with increase in temperature in the range 25-275 C. SRI also measured the rate of solubilization, which is a key factor in determining the reactor parameters. SRI results for fluoranthene, pyrene, chrysene, and 9,10-dimethylanthracene show a linear relationship between rate of solubilization and equilibrium solubility. Also, we …

Attenuation of P-Waves by Wave-Induced Fluid Flow
Analytical expressions for three P-wave attenuation mechanisms in rocks are given and numerically-compared. The mechanisms are: (1) Biot loss, in which flow occurs at the scale of the wavelength between the peaks and troughs of a P wave; (2) squirt loss, in which flow occurs at the grain scale between microcracks the grains and the adjacent pores; and (3) mesoscopic loss, in which flow occurs at intermediate scales between the various lithological bodies that are present in an averaging volume of earth material. Each mechanism is of importance over different frequency bands. Typically, Biot loss is only important at the highest of ultrasonic frequencies (> 1 MHz), squirt-loss (when it occurs) is important in the range of 10 kHz to 1 MHz, while mesoscale loss dominates at the lower frequencies (<10 kHz) employed in seismology.

Children's Health Insurance: Inspector General Reviews Should Be Expanded to Further Inform the Congress
A letter report issued by the General Accounting Office with an abstract that begins "Congress created the State Children's Health Insurance Program (SCHIP) in 1997 to reduce the number of uninsured children in families with incomes that are too high to qualify for Medicaid. Financed jointly by the states and the federal government, SCHIP encourages state participation by offering a higher federal matching rate than the Medicaid program. Concerns have been raised that states might inappropriately enroll Medicaid-eligible children in SCHIP and thus obtain higher federal matching funds than allowed under Medicaid. The Department of Health and Human Services Office of Inspector General (OIG) concluded that Medicaid-eligible children were not being enrolled in SCHIP by the 13 states that administer separate child health care programs. Furthermore, the issue of appropriate enrollment is not limited to states with completely separate child health programs but also applies to those states with combination programs and Medicaid expansions, which also receive the higher SCHIP matching rate. The OIG could not conclude whether states were reducing the number of uninsured children and meeting the objectives and goals they established in their SCHIP programs. The OIG found that some states had set program goals without considering …

Commercial Aviation: Air Service Trends At Small Communities Since October 2000
A letter report issued by the General Accounting Office with an abstract that begins "Most major U.S. airlines began realizing net operating losses early in the 2001, and all of the major U.S. passenger carriers except Southwest Airlines reported losses for the year. Travelers throughout the nation shared in the difficulties. In October 2000, the typical or median small community that GAO analyzed had service from two airlines, with a total of nine daily departing flights. Forty-one percent of the communities were served by only one airline with size being the most obvious factor for service limitations. However, the level of service also varied by the level of local economic activity. The total number of daily departures from these small communities declined by 19 percent between October 2000 and October 2001. Although carriers had reduced total departure levels at small communities before September 11th, airlines made even more reductions after that date. Because profitability is so critical to airline decisions about what markets to serve and how to serve them, the changes in service levels in small communities can be traced to economic factors. Two such factors--the economic decline that began in early 2001 and the collapse of airline passenger …

Debt Collection Improvement Act of 1996: Department of Agriculture's Farm Service Agency Has Not Yet Fully Implemented Certain Key Provisions
A letter report issued by the General Accounting Office with an abstract that begins "The Debt Collection Improvement Act of 1996 seeks to maximize the collection of billions of dollars of nontax delinquent debt owed to the federal government. The act requires agencies to refer eligible debts delinquent more than 180 days to the Department of the Treasury for payment offset and to Treasury or a Treasury-designated debt collection center for cross-servicing. The Treasury Offset Program includes the offset of benefit payments, vendor payments, and tax refunds. Cross-servicing involves locating debtors, issuing demand letters, and referring debts to private collection agencies. The Farm Service Agency (FSA) has initiatives to ensure the timely referral of all delinquent debt. However, the agency's failure to make the act a priority has left key provisions of the legislation unimplemented and has severely reduced opportunities for collection. FSA lacks effective procedures and controls to identify and promptly refer eligible delinquent debts to Treasury for collection action. GAO identified several obstacles to FSA's establishment and implementation of an effective and complete debt-referral process. In the four states with the highest dollar amounts of federal debt excluded from the Treasury Offset Program, GAO reviewed FSA's use of …

Debt Collection Improvement Act of 1996: Major Data Sources Inadequate for Implementing the Debtor Bar Provision
A letter report issued by the General Accounting Office with an abstract that begins "The Debt Collection Improvement Act of 1996 seeks to maximize collections of delinquent nontax debt owed to the federal government. However, the act also seeks to reduce losses by requiring proper screening of potential borrowers and information sharing within and among federal agencies. The major information sources of data on delinquent federal debtors are credit bureau reports, the Department of Housing and Urban Development's Credit Alert Interactive Voice Response System (CAIVRS), and the Financial Management Service's (FMS) Treasury Offset Program's (TOP) database. There is no effective mechanism for federal implementation of the act's debtor bar provision. Although credit bureau reports, CAIVRS, and FMS's TOP database each contain some information on delinquent federal nontax debtors, none provides all-inclusive, timely data or maintains them long enough to serve as an adequate data source for successfully barring future financial assistance to currently delinquent debtors or those who did not meet their past obligations. The TOP database, with modifications, now provides an adequate reference point for identifying delinquent debtors to deny them additional financial assistance. Maximizing the TOP database as a delinquency reporting tool would require several changes, such as …
