A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO provided information on the Internal Revenue Service's (IRS) use of nonaudit contacts with taxpayers, focusing on: (1) the frequency of use, variation in timing, and types of taxpayer responses for three major types of nonaudit contacts; and (2) analyzing the IRS' use of data from the three types of nonaudit contacts to improve compliance and service to taxpayers."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the results of its review of the Joint Strike Fighter (JSF) aircraft program, focusing on whether the acquisition strategy: (1) is designed to demonstrate to a low level of technical risk those critical technologies, processes, and system characteristics necessary to produce an affordable family of strike aircraft that meets all participants' needs before entering engineering and manufacturing development; and (2) is being implemented in a manner that will ensure that this objective will be achieved."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed the National Aeronautics and Space Administration's (NASA) International Space Station, focusing on: (1) areas where the Russian-built Zarya and Service Module do not comply with safety requirements; (2) NASA's review and approval of noncompliances; and (3) whether NASA was due any compensation from the Zarya contractor for noncompliance or performance problems."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed airport screeners' role in enforcing aviation security, focusing on: (1) the causes of screener performance problems in detecting threat objects; (2) the status of efforts being made by the Federal Aviation Administration (FAA) to address these causes; and (3) the screening practices in five other countries as compared with the United States."

Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed federal acquisition issues, focusing on: (1) the changing acquisition environment; (2) recent reform efforts; and (3) current and future challenges in this area."

Five commercial reactor criticals (CRCs) for the LaSalle Unit 1 boiling-water reactor have been analyzed using KENO V.a, the Monte Carlo criticality code of the SCALE 4 code system. The irradiated fuel assembly isotopics for the criticality analyses were provided by the Waste Package Design team at the Yucca Mountain Project in the United States, who performed the depletion calculations using the SAS2H sequence of SCALE 4. The reactor critical measurements involved two beginning-of-cycle and three middle-of-cycle configurations. The CRCs involved relatively low-cycle burnups, and therefore contained a relatively high gadolinium poison content in the reactor assemblies. This report summarizes the data and methods used in analyzing the critical configurations and assesses the sensitivity of the results to some of the modeling approximations used to represent the gadolinium poison distribution within the assemblies. The KENO V.a calculations, performed using the SCALE 44GROUPNDF5 ENDF/B-V cross-section library, yield predicted k{sub eff} values within about 1% {Delta}k/k relative to reactor measurements for the five CRCs using general 8-pin and 9-pin heterogeneous gadolinium poison pin assembly models.

The isotopic composition of mixed-oxide fuel (fabricated with both uranium and plutonium isotopes) discharged from reactors is of interest to the Fissile Material Disposition Program. The validation of depletion codes used to predict isotopic compositions of MOX fuel, similar to studies concerning uranium-only fueled reactors, thus, is very important. The EEI-Westinghouse Plutonium Recycle Demonstration Program was conducted to examine the use of MOX fuel in the San Onofre PWR, Unit I, during cycles 2 and 3. The data, usually required as input to depletion codes, either one-dimensional or lattice codes, were taken from various sources and compiled into this report. Where data were either lacking or determined inadequate, the appropriate data were supplied from other references. The scope of the reactor operations and design data, in addition to the isotopic analyses, was considered to be of sufficient quality for depletion code validation.

The propagation of optical Code Division Multiple Access (CDMA) signals was studied by computer simulation. Group velocity dispersion produces the worst impairment. With dispersion management, the decoder successfully recovers the signals, even in the presence of severe multi-access interference.
