Social Security is the focus of intense public interest. Projected long-range funding problems, public skepticism about its future, and a growing perception that Social Security will not be as good a value for future retirees as it is today are fueling calls for reform. This report discusses a number of the major Social Security issues currently drawing congressional attention.

Social Security is the focus of intense public interest. Projected long-range funding problems, public skepticism about its future, and a growing perception that Social Security will not be as good a value for future retirees as it is today are fueling calls for reform. This report, updated regularly, discusses a number of the major Social Security issues currently drawing congressional attention.

This report provides an overview of the housing issues in the 105th congress.

Water flow in partially saturated fractures under thermal drive may lead to fast flow along preferential localized pathways and heat pipe conditions. At the potential high-level nuclear waste repository at Yucca Mountain, water flowing in fast pathways may ultimately contact waste packages and transport radionuclides to the accessible environment. Sixteen experiments were conducted to visualize heat-driven liquid flow in fracture models that included (1) assemblies of roughened glass plates, (2) epoxy replicas of rock fractures, and (3) a fractured specimen of Topopah Spring tuff. Continuous rivulet flow was observed for high liquid flow rates, intermittent rivulet flow and drop flow for intermediate flow rates, and film flow for lower flow rates and wide apertures. Heat pipe conditions (vapor-liquid counterflow with phase change) were identified in five of the seven experiments in which spatially resolved thermal monitoring was performed, but not when liquid-vapor counterflow was hindered by very narrow apertures, and when inadequate working fluid volume was used.

The NIF PEPC Mechanical Test Stand is to be used in the building 432. Building 432 is being used to test components and processes for NIF. The test stand is to be bolted to the floor. The test stand provides a platform from which the PEPC kinematic repeatability and vibrational characteristics of the PEPC LRU can be tested. The test stand will allow user access to the LRU to install instrumentation and to make adjustments to the kinematics. The mechanical test stand is designed to hold the 1700 lb. PEPC LRU.

Several million cubic feet of hazardous and radioactive waste was buried in shallow pits and trenches within many US Department of Energy (US DOE) sites. The pits and trenches were constructed similarly to municipal landfills with both stacked and random dump waste forms such as barrels and boxes. Many of the hazardous materials in these waste sites are migrating into groundwater systems through plumes and leaching. On-site containment is one of the options being considered for prevention of waste migration. This report describes the results of a proof-of-principle test conducted to demonstrate technology for containing waste. This proof-of-principle test, conducted at the RAHCO International, Inc., facility in the summer of 1997, evaluated equipment techniques for cutting a horizontal slot beneath an existing waste site. The slot would theoretically be used by complementary equipment designed to place a cement barrier under the waste. The technology evaluated consisted of a slot cutting mechanism, muck handling system, thrust system, and instrumentation. Data were gathered and analyzed to evaluate the performance parameters.

U.S. policy on Taiwan is governed by the Taiwan Relations Act (TRA), the 3 U.S. joint communiqués with China, and the so-called "Six Assurances" on Taiwan. This report provides the texts of these documents.

A series of analyses were performed to support the design of the Can Handling Unit (CHU). The subject analyses focused on determining the time to repressurize a subatmospheric storage can containing plutonium metal versus the initial hole size and the transient thermal response to a postulated chemical reaction of 150 grams of plutonium hydride. Limiting the amount of gaseous reactants either by inerting the CHU or using a very small hole size for the initial opening appears to be a viable method of controlling the rate of the exothermic chemical reactions and system temperatures.

This Title III Evaluation Report (TER) provides the results of an evaluation that was conducted on the Material and Personnel Handling System. This TER has been written in accordance with the ''Technical Document Preparation Plan for the Mined Geologic Disposal System Title III Evaluation Reports'' (BA0000000-01717-4600-00005 REV 03). The objective of this evaluation is to provide recommendations to ensure consistency between the technical baseline requirements, baseline design, and the as-constructed Material and Personnel Handling System. Recommendations for resolving discrepancies between the as-constructed system, the technical baseline requirements, and the baseline design are included in this report. Cost and Schedule estimates are provided for all recommended modifications.
