The Idaho National Engineering and Environmental Laboratory (INEEL) Advanced Test Reactor (ATR), a DOE Category A reactor, was designed to provide an irradiation test environment for conducting a variety of experiments. The ATR Safety Analysis Report, determined by DOE to meet the requirements of 10 CFR 830, Subpart B, provides versatility in types of experiments that may be conducted. This paper addresses two general types of experiments in the ATR facility and how safety analyses for experiments are related to the ATR safety basis. One type of experiment is more routine and generally represents greater risks; therefore this type of experiment is addressed with more detail in the safety basis. This allows individual safety analyses for these experiments to be more routine and repetitive. The second type of experiment is less defined and is permitted under more general controls. Therefore, individual safety analyses for the second type of experiment tend to be more unique from experiment to experiment. Experiments are also discussed relative to ''major modifications'' and DOE-STD-1027-92. Application of the USQ process to ATR experiments is also discussed.

We present an update of computer simulation results for some features of the electron cloud at the Large Hadron Collider (LHC) and recent simulation results for the Super Proton Synchrotron (SPS). We focus on the sensitivity of the power deposition on the LHC beam screen to the emitted electron spectrum, which we study by means of a refined secondary electron (SE) emission model recently included in our simulation code.

This report discusses issues debated in the 107th Congress while is considering various proposals to amend the Endangered Species Act of 1973 (ESA). Major issues in recent years have included changing the role of science in decision-making, changing the role of critical habitat, reducing conflicts with Department of Defense activities, incorporating further protection for property owners, and increasing protection of listed species, among others. In addition, many have advocated including significant changes to ESA regulations made during the Clinton Administration in the law itself.

Testimony issued by the General Accounting Office with an abstract that begins "The Immigration and Naturalization Service (INS) developed strategies in the 1990s to control illegal immigration across U.S. borders and to address enforcement priorities within the country. In 1994, INS's Border Patrol issued a strategy to deter illegal entry through "prevention through deterrence;" that is, to raise the risk of being apprehended for illegal aliens to where they would consider it futile to try to enter. The plan called for targeting resources in a phased approach, starting in areas with the greatest illegal activity. In 1999, INS issued its Interior Enforcement Strategy to focus resources on areas that would have the greatest impact on reducing the size and annual growth of the illegal resident population. The strategy established the following five areas: (1) identify and remove criminal aliens and minimize recidivism; (2) deter, dismantle, and diminish smuggling or trafficking of aliens; (3) respond to community reports and complaints about illegal immigration; (4) minimize immigration benefit fraud and other document abuse; and (5) block and remove employers' access to undocumented workers. For these to be effective, INS needs better data to determine staff needs, reliable information technology, clear and consistent …

The Kinetic Stabilizer, employing injected and mirror-reflected ion beams, represents a method for stabilizing axisymmetric mirror and tandem mirror systems. Building on earlier work, this paper presents further calculations on the concept and explores some new options that promise to enhance its capabilities.

The primary research objective of this effort is to develop a portable, capillary electrophoresis microchip capable of sensitively and rapidly monitoring hazardous waste metal ions critical to the successful deactivation and decommissioning (D&D) of contaminated equipment and structures at various DOE sites. Hazardous waste metal ions to be adapted for sensing on the microchip include UO{sub 2}{sup 2+}, Be{sup 2+}, Cr{sup 6+}, Hg{sup 2+}, Pb{sup 2+}, Co{sup 2+}, Ni{sup 2+}, Cs{sup +}, and Sr{sup 2+}. Particular emphasis will be placed on developing viable, new extraction methods for metal ion sampling from both the air via a microimpinger which is integrated onto the microchip itself, and from contaminated surfaces, both techniques being amenable to on-line introduction onto the microchip. Two different detection methods for monitoring the electrophoretic separations taking place down the microchannel will be exploited in this research, indirect and direct detection. Special emphasis will be placed on maintaining the ultimate portability of the final microchip device through the careful selection of metallochromic dyes and fluorophores which are amenable to use of small, inexpensive light sources (e.g., LED's) and photodetectors.

We have used optical velocimetry for 25 years at LLNL to measure velocity-time histories of many dynamic experiments. In certain ones, the shifted light was often quite weak compared to non-shifted light returning from surfaces and imperfections in glass components. In an intensity-measuring VISAR system, this would mean failure, and even with Fabry-Perot (FP) based systems which handle multiple frequencies, data is lost where the fringes coincide. We designed, constructed and successfully used an experimental facility for doing experiments under such conditions by selectively eliminating most of the non-shifted light. Instead of making experimental records which were mostly non-shifted light prior to the use of the filter, we now obtain records where almost all of the light is shifted. The first system had a maximum efficiency of 25% for the desired light, but another version is under construction with a maximum efficiency of over 50%. The first version excluded the non-shifted light by a factor of 300 when manually tuned, and by 150 when run in a Window-based auto-tuning mode. Our first version used a 50 mm diameter FP as the filter with a spacing of 1.65 mm and reflectivities of 77%. It was constructed for use in one of …

An integrated model of a complete discharge in the FIRE experiment has been developed based on the TSC simulation code. The complete simulation model includes a choice of several models for core transport, combined with an edge pedestal model and the Porcelli sawtooth model. Burn control is provided by feedback on the auxiliary heating power. We find that with the GLF23 and MMM95 transport models, Q >10 operation should be possible for H-mode pedestal temperatures in the range of 4-5 keV.

The radiation environment at the NuMI experiment has received a lot of attention in the last few years in preparation for project construction. One important issue is the induced radioactivation of the components in the beam line and the shielding materials. This arises from irradiation by hadrons that are generated in the target. Since the level of the residual activity has to be considered when determining access procedures for maintenance during NuMI operation, an understanding of the properties of the remnant radiation is important. To this end, experimental studies were performed in the target vault at AP0 which is similar in design to the NuMI target area. Here 120 GeV protons bombard a target, generating the hadrons that produce the induced radioactivity. Two sets of samples each consisting of three small cylindrical or rectangular solids of iron and steel, one sample of aluminum, and one of concrete were irradiated. One set was hung just below the bottom of a module near the lithium lens (in-vault), and the other was placed on top of the modules downstream of this location (above-vault), just beneath the movable concrete roof of the vault at AP0. Further, four thin activation foils of Au, Au+Cd, In, …

Other written product issued by the General Accounting Office with an abstract that begins "This report updates GAO's strategic plan for serving Congress from fiscal year 2002-2007. Although the overall framework of the old plan is still valid, greater emphasis is being placed in a number of areas to reflect the altered agenda of policymakers. Recognizing that Congress and the federal government will focus considerable effort and resources on homeland security, GAO is proposing to increasing its emphasis on overseeing the efficiency and effectiveness of effort across the public and private sectors to protect against and respond to various forms of terrorism. In light of the changing public expectations and needs as well as fiscal pressures, GAO has redefined one of its strategic goals to focus on transforming the federal government's role to meet the challenges of the 21st century--what it does and how it does business. Because of the far reaching demographic and fiscal trends that will affect the United States, GAO excepts to add greater long-range focus to its work to support Congress in addressing program priorities and budget decisions."

In studies with positron beams in the Advanced Photon Source, a dramatic amplification was observed in the electron cloud for certain bunch current and bunch spacings. In modeling presented previously, we found qualitative agreement with the observed beam-induced multipacting condition, provided reasonable values were chosen for the secondary electron yield parameters, including the energy distribution. In this paper, we model and discuss the build-up and saturation process observed over long bunch trains at the resonance condition. Understanding this saturation mechanism in more detail may have implications for predicting electron cloud amplification, multipacting, and instabilities in future rings.

Testimony issued by the General Accounting Office with an abstract that begins "Social Security not only represents the foundation of our retirement income system; it also provides millions of Americans with disability insurance and survivor's benefits. Although the Social Security Trustees now project that under the intermediate or "best estimate" assumptions the combined Social Security Trust Funds will be exhausted 3 years later than in last year's estimates, the magnitude of the long-term funding shortfall is virtually unchanged. Without reform, Social Security, Medicare, and Medicaid are unsustainable, and the long-term impact of these entitlement programs on the federal budget and the economy will be dramatic. Social Security reform is part of a larger and significant fiscal and economic challenge. Absent reform, the nation will ultimately have to choose between persistent, escalating federal deficits, significant tax increases, or dramatic budget cuts. Focusing on trust fund solvency alone is not sufficient. Aiming for sustainable solvency would increase the chance that future policymakers would not have to face, on a recurring basis, the difficult questions of whether the government will have the capacity to pay future claims or what else will have to be squeezed to pay those claims. Comparing the beneficiary impact …
