Using FEP's List and a PA Methodology for Evaluating Suitable Areas for the LLW Repository in Italy
In Italy following a referendum held in 1987, nuclear energy has been phased out. Since 1998, a general site selection process covering the whole Italian territory has been under way. A GIS (Geographic Information System) methodology was implemented in three steps using the ESRI Arc/Info and Arc/View platforms. The screening identified approximately 0.8% of the Italian territory as suitable for locating the LLW Repository. 200 areas have been identified as suitable for the location of the LLW Repository, using a multiple exclusion criteria procedure (1:500,000), regional scale (1:100.000) and local scale (1:25,000-1:10,000). A methodology for evaluating these areas has been developed allowing, along with the evaluation of the long term efficiency of the engineered barrier system (EBS), the characterization of the selected areas in terms of physical and safety factors and planning factors. The first step was to identify, on a referenced FEPs list, a group of geomorphological, geological, hydrogeological, climatic and human behavior caused process and/or events, which were considered of importance for the site evaluation, taking into account the Italian situation. A site evaluation system was established ascribing weighted scores to each of these processes and events, which were identified as parameters of the new evaluation system. The …

VA and Defense Health Care: Potential Exists for Savings through Joint Purchasing of Medical and Surgical Supplies
Testimony issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) spent $500 million and the Department of Defense (DOD) spent $240 million for medical and surgical supplies in fiscal year 2001. Since the 1980s, To achieve greater efficiencies through improved acquisition processes and increased sharing of medical resources, VA and DOD signed a memorandum of agreement in 1999 to combine their buying power. VA and DOD saved $170 in 2001 by jointly procuring pharmaceuticals, by agreeing on particular drugs to be purchased, and contracting with the manufacturers for discounts based on their combined larger volume. VA and DOD have not awarded joint national contracts for medical and surgical supplies as envisioned by their memorandum of agreement, and it is unlikely that the two departments will have joint national contracts for supplies anytime soon. However, a few VA and DOD facilities have yielded modest savings through local joint contracting agreements. The lack of progress have made in jointly contracting for medical and surgical supplies has, in part, been the result of their different approaches to standardizing medical and surgical supplies. Other impediments to joint purchasing have been incomplete procurement data and the inability …

VA Information Technology: Management Making Important Progress in Addressing Key Challenges
Testimony issued by the General Accounting Office with an abstract that begins "In March of this year, GAO testified before the House Subcommittee on Oversight and Investigations, Committee on Veterans' Affairs, about the Department of Veterans Affairs' (VA) information technology (IT) program, and the strides that the Secretary had made in improving departmental leadership and management of this critical area--including the hiring of a chief information officer. At the Subcommittee's request, GAO evaluated VA's new IT organizational structure, and provided an update on VA's progress in addressing other specific areas of IT concern and our related recommendations pertaining to enterprise architecture, information security, the Veterans Benefits Administration's replacement compensation and pension payment system and maintenance of the Benefits Delivery Network, and the government computer-based patient record initiative."

Veterans' Benefits: Despite Recent Improvements, Meeting Claims Processing Goals Will Be Challenging
Testimony issued by the General Accounting Office with an abstract that begins "The Department of Veterans Affairs (VA) will provide $25 billion in compensation and pension benefits in fiscal year 2002 to more than three million veterans, dependents and survivors. For years, the compensation and pension claims process has been subject to long long waits for decision and large claims backlogs. VA's goal for fiscal year 2003 is to complete accurate decisions on rating-related claims in an average of 100 days. To achieve this, the Veterans Benefits Administration (VBA) is focusing on increasing production of rating decisions and reducing the inventory of claims to about 250,000. As of the end of March 2002, VBA was completing claims in an average of 224 days and had an inventory of about 412,000 claims. VBA is trying to significantly increase regional offices' rating decision production to reduce the inventory, and, in turn, reduce the time required to complete decisions. VBA expects to increase production by hiring more staff and increasing the proficiency of new staff. Although VBA has recently increased its production and reduced its inventory, meeting its production and inventory reduction and its timeliness goals will be challenging."

Vibrational and Electronic Properties of Fullerene and Carbon-Based Clustors. Final Reports for period July 1, 1997 - June 30, 2001
Lattice dynamics is of central importance for the mechanism of ferroelectricity. In particular, the soft mode behaviors are directly related to many of their ferroelectric and dielectric properties. In this project, we have carried out experimental studies of the vibrational spectra of SrTiO{sub 3} films grown by pulsed laser deposition using a metal-oxide bilayer structure. Raman scattering, with and without bias electric field, and Fourier-transform far-infrared ellipsometry were utilized. These results are compared with the low-frequency dielectric properties. We found that in the films the soft mode is harder compared to that in bulk crystals, in agreement with the Lyddane-Sachs-Teller (LST) formalism. We have studied electric field-induced Raman scattering in SrTiO{sub 3} thin films using an indium-tin oxide/SrTiO{sub 3}/SrRuO{sub 3} structure. The soft mode polarized along the field becomes Raman active. Experimental data for electric field-induced hardening of the soft modes and the tuning of the static dielectric constant are in agreement described by the LST formalism. The markedly different behavior of the soft modes in thin films from that in the bulk is explained by the existence of local polar regions. The study was extended to Ba{sub x}Sr{sub 1-x}TiO{sub 3} films with Ba contents x = 0.05, 0.1, 0.2 …

The Waste Isolation Pilot Plant: A Success Story with International Cooperation
The U.S. Department of Energy (DOE) Carlsbad Field Office (CBFO) administers and operates the Waste Isolation Pilot Plant (WIPP) site, which hosts a deep geologic repository for safe disposal of U.S. defense-related TRU waste and is located 42 kilometers (km) east of Carlsbad, New Mexico. CBFO also manages the National Transuranic Waste Program (NTP), which oversees TRU waste management from generation to disposal. The WIPP began receiving waste in March 1999. In some areas of broad international interest, the CBFO has developed a leading expertise through its 25-year WIPP repository and TRU waste characterization activities. In addition to participating in relevant and beneficial experiments, the CBFO will provide the international community convenient access to this information by sponsoring and hosting symposia and workshops on relevant topics and by participation in international waste management organizations and topical meetings. In recognition of the successes at WIPP, the Inter national Atomic Energy Agency (IAEA) has designated WIPP as an International Center of Excellence and part of IAEA's Network of Centers of Excellence. The IAEA will foster cooperative training in and demonstration of waste disposal technologies in underground research facilities (URFs).such as WIPP. The CBFO, supported by its Science Advisor, has agreed to exchange …

Waste Issues Associated with the Safe Movement of Hazardous Chemicals
Moving hazardous chemicals presents the risk of exposure for workers engaged in the activity and others that might be in the immediate area. Adverse affects are specific to the chemicals and can range from minor skin, eye, or mucous membrane irritation, to burns, respiratory distress, nervous system dysfunction, or even death. A case study is presented where in the interest of waste minimization; original shipping packaging was removed from a glass bottle of nitric acid, while moving corrosive liquid through a security protocol into a Radiological Control Area (RCA). During the transfer, the glass bottle broke. The resulting release of nitric acid possibly exposed 12 employees with one employee being admitted overnight at a hospital for observation. This is a clear example of administrative controls to reduce the generation of suspect radioactive waste being implemented at the expense of employee health. As a result of this event, material handling procedures that assure the safe movement of hazardous chemicals through a security protocol into a radiological control area were developed. Specifically, hazardous material must be transferred using original shipping containers and packaging. While this represents the potential to increase the generation of suspect radioactive waste in a radiological controlled area, arguments …

Waste Minimization Policy at the Romanian Nuclear Power Plant
The radioactive waste management system at Cernavoda Nuclear Power Plant (NPP) in Romania was designed to maintain acceptable levels of safety for workers and to protect human health and the environment from exposure to unacceptable levels of radiation. In accordance with terminology of the International Atomic Energy Agency (IAEA), this system consists of the ''pretreatment'' of solid and organic liquid radioactive waste, which may include part or all of the following activities: collection, handling, volume reduction (by an in-drum compactor, if appropriate), and storage. Gaseous and aqueous liquid wastes are managed according to the ''dilute and discharge'' strategy. Taking into account the fact that treatment/conditioning and disposal technologies are still not established, waste minimization at the source is a priority environmental management objective, while waste minimization at the disposal stage is presently just a theoretical requirement for future adopted technologies . The necessary operational and maintenance procedures are in place at Cernavoda to minimize the production and contamination of waste. Administrative and technical measures are established to minimize waste volumes. Thus, an annual environmental target of a maximum 30 m3 of radioactive waste volume arising from operation and maintenance has been established. Within the first five years of operations at …

Waste Stream Generated and Waste Disposal Plans for Molten Salt Reactor Experiment at Oak Ridge National Laboratory
The Molten Salt Reactor Experiment (MSRE) site is located in Tennessee, on the U.S. Department of Energy (DOE) Oak Ridge Reservation (ORR), south of the Oak Ridge National Laboratory (ORNL) main plant across Haw Ridge in Melton Valley. The MSRE was run by ORNL to demonstrate the desirable features of the molten-salt concept in a practical reactor that could be operated safely and reliably. It introduced the idea of a homogeneous reactor using fuel salt media and graphite moderation for power and breeder reactors. The MSRE reactor and associated components are located in cells beneath the floor in the high-bay area of Building 7503 (Figure 1). The reactor was operated from June 1965 to December 1969. When the reactor was shut down, fuel salt was drained from the reactor circuit to two drain tanks. A ''clean'' salt was then circulated through the reactor as a decontamination measure and drained to a third drain tank. When operations ceased, the fuel and flush salts were allowed t o cool and solidify in the drain tanks. At shutdown, the MSRE facility complex was placed in a surveillance and maintenance program. As a result of the S&M program, it was discovered in 1994 that …

Worker Protection: Labor's Efforts to Enforce Protections for Day Laborers Could Benefit from Better Data and Guidance
A letter report issued by the General Accounting Office with an abstract that begins "Day laborers generally are individuals who work and get paid on a daily or short-term basis. To find work, they often congregate on street corners and wait for employers to drive by and offer them work. Day laborers may also be employed by temporary staffing agencies that assign them work on a daily basis with client employers. Day laborers have an informal relationship with the labor market, often working for different employers each day, being paid in cash, and lacking key benefits, such as health or unemployment insurance. However, day laborers may be eligible for wage and safety protections provided by the Fair Labor Standards Act (FLSA) and the Occupational Safety and Health (OSH) Act. The U.S. Department of Labor administers both acts. Its Wage and Hour Division (WHD) is responsible for ensuring that all covered workers receive at least the federal minimum hourly wage and overtime pay. The Occupational Safety and Health Administration (OSHA) is required to ensure that employers provide safe and healthy workplaces to help their workers avoid injury or death. Coverage under both laws does not depend on a worker's immigration status. …

X-ray lenses fabricated by deep x-ray lithography.
Refractive x-ray lenses have been fabricated using deep x-ray lithography. Lenses were produced directly in 1- to 6-mm-thick sheets of polymethylmethacrylate (PMMA) with as many as 100 cylindrical lenses along the optical axis. The fabrication process consists of exposing the PMMA sheets to high-energy synchrotron radiation through a mask of 50-micron-thick gold on silicon and subsequent development in ketone. The lenses are suitable for use in synchrotron radiation from a bending magnet at the Advanced Photon Source in the energy range of 8-16 keV. Results of measurements of focus quality, flux density gain, and scatter are presented and discussed with regard to the quality of lens material and fabrication method. Means for improving the performance of the lenses is discussed.

YUCCA MOUNTAIN PROJECT RECOMMENDATION BY THE SECRETARY OF ENERGY REGARDING THE SUITABILITY OF THE YUCCA MOUNTAIN SITE FOR A REPOSITORY UNDER THE NUCLEAR WASTE POLICY ACT OF 1982
For more than half a century, since nuclear science helped us win World War II and ring in the Atomic Age, scientists have known that !he Nation would need a secure, permanent facility in which to dispose of radioactive wastes. Twenty years ago, when Congress adopted the Nuclear Waste Policy Act of 1982 (NWPA or ''the Act''), it recognized the overwhelming consensus in the scientific community that the best option for such a facility would be a deep underground repository. Fifteen years ago, Congress directed the Secretary of Energy to investigate and recommend to the President whether such a repository could be located safely at Yucca Mountain, Nevada. Since then, our country has spent billions of dollars and millions of hours of research endeavoring to answer this question. I have carefully reviewed the product of this study. In my judgment, it constitutes sound science and shows that a safe repository can be sited there. I also believe that compelling national interests counsel in favor of proceeding with this project. Accordingly, consistent with my responsibilities under the NWPA, today I am recommending that Yucca Mountain be developed as the site for an underground repository for spent fuel and other radioactive wastes. …

Zero Temperature Hope Calculations
The primary purpose of the HOPE code is to calculate opacities over a wide temperature and density range. It can also produce equation of state (EOS) data. Since the experimental data at the high temperature region are scarce, comparisons of predictions with the ample zero temperature data provide a valuable physics check of the code. In this report we show a selected few examples across the periodic table. Below we give a brief general information about the physics of the HOPE code. The HOPE code is an ''average atom'' (AA) Dirac-Slater self-consistent code. The AA label in the case of finite temperature means that the one-electron levels are populated according to the Fermi statistics, at zero temperature it means that the ''aufbau'' principle works, i.e. no a priory electronic configuration is set, although it can be done. As such, it is a one-particle model (any Hartree-Fock model is a one particle model). The code is an ''ion-sphere'' model, meaning that the atom under investigation is neutral within the ion-sphere radius. Furthermore, the boundary conditions for the bound states are also set at the ion-sphere radius, which distinguishes the code from the INFERNO, OPAL and STA codes. Once the self-consistent AA …
