McCarter superfinish grinding for silicon -- an update.
A grinding technique, referred to as the McCarter Superfinish, for grinding large size optical components is discussed and certain surface characterization information about flatness and the relative magnitude of the subsurface damage in silicon substrates is reported. The flatness measurements were obtained with a Zygo surface analyzer, and the substrate damage measurements were made by x-ray diffraction and acid etching. Results indicate excellent control of flatness and fine surface finish. X-ray measurements show that the diamond wheels with small particle sizes used in the final phases of the grinding operation renders surfaces with relatively small subsurface damage.

Design Verification Report Spent Nuclear Fuel (SNF) Project Canister Storage Building (CSB)
The Sub-project W379, ''Spent Nuclear Fuel Canister Storage Building (CSB),'' was established as part of the Spent Nuclear Fuel (SNF) Project. The primary mission of the CSB is to safely store spent nuclear fuel removed from the K Basins in dry storage until such time that it can be transferred to the national geological repository at Yucca Mountain Nevada. This sub-project was initiated in late 1994 by a series of studies and conceptual designs. These studies determined that the partially constructed storage building, originally built as part of the Hanford Waste Vitrification Plant (HWVP) Project, could be redesigned to safely store the spent nuclear fuel. The scope of the CSB facility initially included a receiving station, a hot conditioning system, a storage vault, and a Multi-Canister Overpack (MCO) Handling Machine (MHM). Because of evolution of the project technical strategy, the hot conditioning system was deleted from the scope and MCO welding and sampling stations were added in its place. This report outlines the methods, procedures, and outputs developed by Project W379 to verify that the provided Structures, Systems, and Components (SSCs): satisfy the design requirements and acceptance criteria; perform their intended function; ensure that failure modes and hazards have been …

Investigation of Ground-Fault Protection Devices for Photovoltaic Power Systems Applications
Photovoltaic (PV) power systems, like other electrical systems, may be subject to unexpected ground faults. Installed PV systems always have invisible elements other than those indicated by their electrical schematics. Stray inductance, capacitance and resistance are distributed throughout the system. Leakage currents associated with the PV modules, the interconnected array, wires, surge protection devices and conduit add up and can become large enough to look like a ground-fault. PV systems are frequently connected to other sources of power or energy storage such as batteries, standby generators, and the utility grid. This complex arrangement of distributed power and energy sources, distributed impedance and proximity to other sources of power requires sensing of ground faults and proper reaction by the ground-fault protection devices. The different dc grounding requirements (country to country) often add more confusion to the situation. This paper discusses the ground-fault issues associated with both the dc and ac side of PV systems and presents test results and operational impacts of backfeeding commercially available ac ground-fault protection devices under various modes of operation. Further, the measured effects of backfeeding the tripped ground-fault devices for periods of time comparable to anti-islanding allowances for utility interconnection of PV inverters in the United …

1999 Annual Cathodic Protection Survey Report for PFP
This cathodic protection (CP) report documents the results of the 1999 annual CP survey of the underground piping within PFP property. An annual survey of CP systems is required by Washington Administrative Code (WAC). A spreadsheet to document the 1999 annual survey polarization data is included in this report. Graphs are included to trend the cathodic voltages and the polarization voltages at each test station on PFP property. The trending spans from 1994 to 1999. Graphs are also included to trend voltage and amperage outputs of each rectifier during the annual surveys. During the annual survey, resistance testing between the underground piping was conducted at each test station. The testing showed that all piping (with test leads into the test stations) was continuous with every pipe represented in the test stations. The resistance data is not documented in this report but can be accessed in work package 22-99-01003. During the annual survey, the wiring configurations of anode junction boxes AJB(R45-1) and AJB(45-1) were documented. The sketches can be accessed from the JCS work record of work package 22-99-01003. Analysis, conclusions, and recommendations of the 1999 annual CP survey results are included in this report.

Test Plan and Test Specifications for Unloading LR-56 Waste at the 204-AR Waste Unloading Facility
The LR-56 cask is an International Atomic Energy Agency (IAEA), type B (U) certified Medium to High Level Radioactive Liquid Waste Transport Cask. The LR-56 consists of a trailer equipped with the following component and systems: cubic meter lead shielded cask; Self-contained ventilation system including an air pressure/vacuum pump for cask loading and unloading; Waste temperature, level, leak detection, and other surveillance equipment; Control room for control of loading and unloading operations and waste surveillance; Hoist system for removing well caps on the cask; Power connection and control connections for operating the cask from a remote facility; The cask may be unloaded or loaded using either the onboard pressure/vacuum pump or by an external waste transfer pump. Rinse heads and connections allow the cask to be rinsed using supplied rinse water. The cask was designed to be vented using the LR-56 onboard ventilation system, which is connected to the cask via a hose through a penetration in the cask. Three wells located on the top of the cask, offer valved penetrations into the cask for venting, waste pumping, and rinsing. Other penetrations in the cask enable surveillance instrumentation to be used to monitor inside the cask. To date, the LR-56 …

Authority of a President to Modify or Eliminate a National Monument
President Clinton created a number of new national monuments, using authority given the President under the Antiquities Act of 1906. Many of the designations were controversial and renewed discussion of that Act and whether a President can modify or eliminate a Presidentially created national monument. This report examines that question.

The Heavy Ion Fusion Program in the U.S.A.
Inertial fusion energy research has enjoyed increased interest and funding. This has allowed expanded programs in target design, target fabrication, fusion chamber research, target injection and tracking, and accelerator research. The target design effort examines ways to minimize the beam power and energy and increase the allowable focal spot size while preserving target gain. Chamber research for heavy ion fusion emphasizes the use of thick liquid walls to serve as the coolant, breed tritium, and protect the structural wall from neutrons, photons, and other target products. Several small facilities are now operating to model fluid chamber dynamics. A facility to study target injection and tracking has been built and a second facility is being designed. Improved economics is an important goal of the accelerator research. The accelerator research is also directed toward the design of an Integrated Research Experiment (IRE). The IRE is being designed to accelerate ions to >100 MeV, enabling experiments in beam dynamics, focusing, and target physics. Activities leading to the IRE include ion source development and a High Current Experiment (HCX) designed to transport and accelerate a single beam of ions with a beam current of approximately 1 A, the initial current required for each beam …

Nuclear Nonproliferation Policy
Preventing the acquisition of nuclear weapons is a longstanding goal of U.S. national security policy. Five countries are recognized as having legal status as nuclear weapons states: United States, Russia, China, United Kingdom, and France. All five signed the Nonproliferation Treaty (NPT), which recognizes only these five that tested nuclear weapons before 1968 as de jure nuclear weapons states. Three more: India, Israel, and Pakistan, have significant nuclear capabilities, but are not members of the NPT. India and Pakistan tested nuclear weapons in May 1998.
