Single Element Flow Tests for Type 3 (SM-2) Fuel Elements in SM-1, SM-1A, and PM-2A Cores
Channel-to-channel flow distribution within Type 3 (SM-2, stationary and control rod fuel elements modified for use in the SM-1, SM1-1A, and PM-2A core support structures and control rod tubes was measured in single element flow testing. Plots of channel-to-channel flow distribution and element pressure drop at various element flow rates are given. Flow distribution for the top-orificed SM-1A and PM-2A stationary elements was within the plus or minus 12% deviation from element average utilized in previous thermal analyses of these cores. Testing of the bottom-orificed SM-1 stationary element and the SM-1, SM-1A, and PM-2A control rod assemblies showed flow distribution exceeded plus or minus 12% devation from average. Simple modifications to the SM-1 stationary element indicated the possibility of improvng fiow distribution in that element. (auth)

Mine Safety and Health Administration: Implementation of the Inflation Adjustment Act
Correspondence issued by the General Accounting Office with an abstract that begins "The Federal Civil Penalties Inflation Adjustment Act of 1990 went under a governmentwide review by GAO earlier this year. The act required each federal agency to issue a regulation adjusting its covered maximum and minimum civil monetary penalties for inflation by October 23, 1996, and requires them to make necessary adjustments at least once every 4 years thereafter. GAO determined that the Mine Safety and Health Administration within the Department of Labor published its first round of penalty adjustments in April 1998, but has not published a second round of adjustments for at least two eligible penalties."

Medicare+Choice: Oversight Lapses in HCFA's Review of Humana's 1998 Florida Contract
Correspondence issued by the General Accounting Office with an abstract that begins "Humana, Inc., a large Medicare Choice Plan, provided a prescription drug benefit with a coverage limit that was below the amount listed in its 1998 Florida Medicare Choice contract. Ernst and Young, the contractor hired by the Health Care Financing Administration (HCFA) to review Humana's contract submission, did not detect the discrepancies because it failed to follow HCFA's review procedures. HCFA has revised its processes and procedures for monitoring the accuracy of the information in Medicare Choice plans' contracts. The Humana case shows that the agency did not follow procedures that could have revealed the contract discrepancies that caused some beneficiaries to receive less coverage for brand name prescription drugs than the amount specified in their plan's basic package. Unless HCFA adheres to its revised monitoring procedures, beneficiaries will have few guarantees that they will receive the prescription drug benefits for which the government contracted and paid."

Justice Discretionary Grants: Byrne Program and Violence Against Women Office Grant Monitoring Should Be Better Documented
A letter report issued by the General Accounting Office with an abstract that begins "GAO reviewed grant monitoring and evaluation efforts by the U.S. Department of Justice's (DOJ) Office of Justice Program (OJP). This report discusses the monitoring of discretionary grants awarded by the Bureau of Justice Assistance's (BJA) Byrne Program and the Violence Against Women Office (VAWO) within OJP. In constant 2000 dollars, Byrne and VAWO discretionary grants grew about 85 percent--from $105 million to $194 million between fiscal years 1997 and 2000. These funds were awarded to state and local governments, either on a competitive basis or pursuant to legislation allocating funds through congressional earmarks. BJA and VAWO, together with OJP's Office of the Comptroller, are responsible for monitoring these grants to ensure they are implemented as intended, are responsive to grant goals and objectives, and comply with statutory regulations and policy guidelines. OJP's monitoring requirements include the development of monitoring plans that articulate who will conduct monitoring, the manner in which it will be done, and when and what type of monitoring activities are planned. Grant managers are to maintain documentation in grant files using such techniques as written reports of on-site reviews and telephone interview write-ups. …

Social Security Death Data: Additional Action Needed to Address Data Errors and Federal Agency Access
A letter report issued by the Government Accountability Office with an abstract that begins "The Social Security Administration (SSA) receives death reports from multiple sources, including state vital records agencies (states), family members, and other federal agencies to create its set of death records. In accordance with the Social Security Act (Act), SSA shares its full set of death data with certain agencies that pay federally-funded benefits, for the purpose of ensuring the accuracy of those payments. For other users of SSA's death data, SSA extracts a subset of records into a file called the Death Master File (DMF), which, to comply with the Act, excludes state-reported death data. SSA makes the DMF available via the Department of Commerce's National Technical Information Service, from which any member of the public can purchase DMF data. Certain procedures that SSA uses for collecting, verifying, and maintaining death reports could result in erroneous or untimely death information. For example, SSA does not independently verify all reports before including them in its death records. In accordance with its policy, the agency only verifies death reports for Social Security beneficiaries in order to stop benefit payments, and then, verifies only those reports from sources it …

Securities Regulation: Improvements Needed in the Amex Listing Program
A letter report issued by the General Accounting Office with an abstract that begins "The Securities and Exchange Commission (SEC) has indicated that one-third of Amex's new listings did not meet the exchange's equity listing standards. Amex's listing guidelines address factors that are the same or similar to those addressed by other U.S. stock markets. Quantitative requirements addressed share price, stockholders' equity, income, and market value of publicly held shares. However, the minimum thresholds for meeting these requirements varied to reflect the differences in the companies that each market targeted for listing. The most significant difference between Amex's guidelines and the listing standards of other U.S. stock markets was that Amex was one of only two markets that retained discretion to initially list companies that did not meet all of its quantitative requirements. Amex had not implemented the Office of Compliance Inspections and Examinations' (OCIE) recommendations on the exchange's discretionary listing decisions. OCIE officials told GAO that in the absence of an Amex agreement to address the recommendations, they would include them among the open significant recommendations to be reported to the SEC Commissioners as a result of a 1998 GAO recommendation. The Commission can require Amex to implement OCIE's …

Overseas Presence: More Work Needed on Embassy Rightsizing
A letter report issued by the General Accounting Office with an abstract that begins "The Department of State is leading an interagency assessment of staffing needs in U.S. embassies and consulates to improve mission effectiveness and reduce security vulnerabilities and costs. This process, called "rightsizing," was begun in response to the recommendations of the Overseas Presence Advisory Panel. In the aftermath of the August 1998 bombings of U.S. embassies in Africa, the Panel determined that overseas staffing levels had not been adjusted to reflect changing missions and requirements; thus, some embassies and consulates were overstaffed, and others were understaffed. The Panel recommended a rightsizing strategy to improve security by reducing the number of embassy staff at risk. The Panel also recommended the establishment of a permanent committee to regularly adjust the U.S. presence, and the adoption of explicit criteria to guide decisions on the size and location of posts. A State-led interagency committee conducted pilot studies at six embassies in 2000 to (1) develop a methodology for assessing staffing at embassies and consulates during the next five years and (2) recommend adjustments to staffing levels at the embassies studied. The interagency committee formed teams that visited U.S. embassies in Amman, …

Securities Operations: Update on Actions Taken to Address Day Trading Concerns
A letter report issued by the General Accounting Office with an abstract that begins "Concerns arose in the late 1990s about day trading, particularly the use of questionable advertising to attract customers without fully disclosing or by downplaying the risks involved. Concerns were also raised that traders were losing large amounts of money. Day traders as a group and day trading firms have continued to evolve and are generally more experienced and sophisticated about securities markets and investing than was the case several years ago. Likewise, day trading firms' operations have evolved, and many have shifted their primary focus away from retail customers and toward attracting institutional customers, such as hedge funds and money market managers. Furthermore, more firms are likely to engage in proprietary trading activities through professional traders that trade the firms' own capital. Finally, although the number of day trading firms appears to have remained constant, several day trading firms have been acquired by other brokerages and market participants whose customers want the direct access to securities markets and market information that technology used by day trading firms provides. Since GAO's 2000 review, the Securities and Exchange Commission and the self-regulatory organizations have addressed many of the …

Reservoir characteristics in Uinta basin gas wells. Final report, September 1, 1978-January 31, 1980
Volumes of 29 lenticular tight gas sandstone reservoirs in the Uinta Basin, Utah have been approximated from long-term pressure buildups on 6 wells. Average reservoir volume was interpreted to be about 240,000 ft/sup 3/ per ft of net pay. Outcrop reservoir geometry studies indicate an average reservoir volume (without any reservoir interconnection assumed) of about 30% less than the average based upon production analysis. Therefore, some reservoir interconnection may exist. Results of this study are consistent with the Knutson lenticular reservoir model in which average reservoir width is 22 times the gross sand thickness, length is 10 times the width, and reservoir interconnection is a function of the sand fraction in the productive interval. Apparent reservoir permeabilities, assuming radial flow, range from .009 to .052 millidarcies and actual sandstone matrix permeabilities are interpreted to range from .06 to .21 millidarcies. Fracture half lengths are interpreted to be about 0.1 ft/bbl of fluid with an average proppant load of 1.2 to 1.7 lb/gal at injection rates of 18 to 24 BPM and injection pressures of 2,500 to 4,600 psi for each 100 ft of gross sand in the fracced interval.

Strangelet Search at the BNL Relativistic Heavy Ion Collider
We have searched for strangelets in a triggered sample of 61 million central (top 4percent) Au+Au collisions at sqrt sNN = 200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion Collider. We have sensitivity to metastable strangelets with lifetimes of order>_0.1 ns, in contrast to limits over ten times longer in BNL Alternating Gradient Synchrotron (AGS) studies and longer still at the CERN Super Proton Synchrotron (SPS). Upper limits of a few 10-6 to 10-7 per central Au+Au collision are set for strangelets with mass>~;;30 GeV/c2.

Seismic imaging of reservoir flow properties: Resolving waterinflux and reservoir permeability
Methods for geophysical model assessment, in particuale thecomputation of model parameter resolution, indicate the value and thelimitations of time-lapse data in estimating reservoir flow properties. Atrajectory-based method for computing sensitivities provides an effectivemeans to compute model parameter resolutions. We examine the commonsituation in which water encroaches into a resrvoir from below, as due tothe upward movement of an oil-water contact. Using straight-forwardtechniques we find that, by inclusing reflections off the top and bottomof a reservoir tens of meters thick, we can infer reservoir permeabilitybased upon time-lapse data. We find that, for the caseof water influxfrom below, using multiple time-lapse 'snapshots' does not necessarilyimprove the resolution of reservoir permeability. An application totime-lapse data from the Norne field illustrates that we can resolve thepermeability near a producing well using reflections from threeinterfaces associated with the reservoir.

Radiation damage to BSCCO-2223 from 50 MEV protons.
The use of HTS materials in high radiation environmentsrequires that the superconducting properties remain constant up to aradiation high dose. BSCCO-2223 samples from two manufacturers wereirradiated with 50 MeV protons at fluences of up to 5 x 1017 protons/cm2.The samples lost approximately 75 percent of their pre-irradiation Ic.This compares with Nb3Sn, which loses about 50 percent at the samedisplacements per atom.

Analysis of Order Formation in Block Copolymer Thin Films UsingResonant Soft X-Ray Scattering
The lateral order of poly(styrene-block-isoprene) copolymer(PS-b-PI) thin films is characterized by the emerging technique ofresonant soft X-ray scattering (RSOXS) at the carbon K edge and comparedto ordering in bulk samples of the same materials measured usingconventional small-angle X-ray scattering. We show resonance using theoryand experiment that the loss of scattering intensity expected with adecrease in sample volume in the case of thin films can be overcome bytuning X-rays to the pi* resonance of PS or PI. Using RSOXS, we study themicrophase ordering of cylinder- and phere-forming PS-b-PI thin films andcompare these results to position space data obtained by atomic forcemicroscopy. Our ability to examine large sample areas (~;9000 mu m2) byRSOXS enables unambiguous identification of the lateral lattice structurein the thin films. In the case of the sphere-forming copolymer thin film,where the spheres are hexagonally arranged, the average sphere-to-spherespacing is between the bulk (body-centered cubic) nearest neighbor andbulk unit cell spacings. In the case of the cylinder-forming copolymerthin film, the cylinder-to-cylinder spacing is within experimental errorof that obtained in the bulk.

Characterization of Nuclear Fuel using Multivariate Statistical Analysis
Various combinations of reactor type and fuel composition have been characterized using principle components analysis (PCA) of the concentrations of 9 U and Pu isotopes in the 10 fuel as a function of burnup. The use of PCA allows the reduction of the 9-dimensional data (isotopic concentrations) into a 3-dimensional approximation, giving a visual representation of the changes in nuclear fuel composition with burnup. Real-world variation in the concentrations of {sup 234}U and {sup 236}U in the fresh (unirradiated) fuel was accounted for. The effects of reprocessing were also simulated. The results suggest that, 15 even after reprocessing, Pu isotopes can be used to determine both the type of reactor and the initial fuel composition with good discrimination. Finally, partial least squares discriminant analysis (PSLDA) was investigated as a substitute for PCA. Our results suggest that PLSDA is a better tool for this application where separation between known classes is most important.

CRISPR - a Widespread System That Provides Acquired Resistance Against Phages in Bacteria and Archaea
Arrays of clustered, regularly spaced short palindromic repeats (CRISPR) are widespread in the genomes of many bacteria and almost all archaea. These arrays are composed of direct repeats sized 24-47 bp separated by similarly sized non-repetitive sequences (spacers). It was recently experimentally shown that CRISPR arrays, along with a group of associated proteins, confer resistance to phage. Following exposure to phage, bacteria integrate new spacer sequences that are derived from the phage genome. Acquisition of these spacers enables the bacterial cell to shutdown the phage attack, presumably by an RNA-interference-like mechanism. This progress discusses the structure and function of CRISPRs and the implications of his new antiviral mechanisms in bacteria.
