A letter report issued by the General Accounting Office with an abstract that begins "The first Internet pharmacies began online service in early 1999. Public health officials are concerned about Internet pharmacies that do not adhere to state licensing requirements and standards. Public officials are also concerned about the validity of prescriptions and international drugs that are not approved in the United States being sent by mail. The unique qualities of the Internet pose new challenges for enforcing state pharmacy and medical practice laws because they allow pharmacies and physicians to reach consumers across state and international borders and remain anonymous. Congress is considering legislation to strengthen oversight of Internet pharmacies."

We report on the raw disk i/o performance of a set of Compaq StorageWorks RAID arrays connected to our cluster of Compaq ES40 computers via Fibre Channel. The best cumulative peak sustained data rate is l17MB/s per node for reads and 77MB/s per node for writes. This value occurs for a configuration in which a node has two Fibre Channel interfaces to a switch, which in turn has two connections to each of two Compaq StorageWorks RAID arrays. Each RAID array has two HSG80 RAID controllers controlling (together) two 5+p RAID chains. A 10% more space efficient arrangement using a single 1l+p RAID chain in place of the two 5+P chains is 25% slower for reads and 40% slower for writes.

These valves are 1/4-inch ball valves fabricated of 316 stainless steel. Packing is TFE (standard). They are used as normally closed isolation valves for test ports in the SCHe System between the gage root valve and the pressure indicator.

This as-built verification plan outlines the methodology and responsibilities that will be implemented during the as-built field verification activity for the Canister Storage Building (CSB) MCO HANDLING MACHINE (MHM). This as-built verification plan covers THE ELECTRICAL PORTION of the CONSTRUCTION PERFORMED BY POWER CITY UNDER CONTRACT TO MOWAT. The as-built verifications will be performed in accordance Administrative Procedure AP 6-012-00, Spent Nuclear Fuel Project As-Built Verification Plan Development Process, revision I. The results of the verification walkdown will be documented in a verification walkdown completion package, approved by the Design Authority (DA), and maintained in the CSB project files.

The BAGPIPE sub-critical experiment was executed on September 26, 1998, at about 13:07 hours. A steel and fibercrete containment barrier had been built at the entrance to the U1a.101b drift at the Nevada Test Site to form the BAGPIPE zero-room. The invert of the zero-room was covered with concrete and the ribs and back were covered with about 15 cm of fibercrete. The face was left uncovered to facilitate gas bleed-off into the alluvial formation. The volume of the room was approximately 3894 ft{sup 3}. Four small experimental packages were detonated. The LLNL containment goal for the BAGPIPE experiment was to confine all special nuclear material (SNM) to the zero-room and the alluvium surrounding the zero-room. The experiment and containment objectives are discussed more fully in the BAGPIPE Containment Prospectus and the associated addendum. Alpha-particle radiation detectors outside the BAGPIPE zero-room remained at pre-shot background levels after the experiment. A large number of swipes were taken around the BAGPIPE primary containment barrier and in the diagnostics room. No evidence that any SNM was released into the tunnel complex was found and the BAGPIPE containment was considered successful.

Yucca Mountain comprises a series of north-trending ridges composed of tuffs within the southwest Nevada volcanic field, 120 km northwest of Las Vegas, Nevada. These ridges are formed of east-dipping blocks of interbedded welded and nonwelded tuff that are offset along steep, mostly west-dipping faults that have tens to hundreds of meters of vertical separation. Yucca Mountain is currently under study as a potential site for underground storage of high-level radioactive waste, with the principle goal being the safe isolation of the waste from the accessible environment. To this end, an understanding of the behavior of ground-water flow through the mountain in the unsaturated zone and beneath the mountain in the saturated zone is critical. The percolation of water through the mountain and into the ground-water flow system beneath the potential repository site is predicated on: (1) the amount of water available at the surface as a result of the climatic conditions, (2) the hydrogeologic characteristics of the volcanic strata that compose the mountain. and (3) the hydrogeologic characteristics of the structures, particularly fault zones and fracture networks, that disrupt these strata. This paper addresses the hydrogeologic characteristics of the fault zones at Yucca Mountain, focusing primarily on the central …

A numerical ground-water flow model is being constructed for the Death Valley regional ground-water system, an area that encompasses approximately 80,000 km{sup 2} in southern Nevada and southeastern California. Effective construction and calibration of the regional-scale steady-state flow model, developed using MODFLOW-2000, is dependent upon integration of hydrogeologic data and parameter-estimation techniques. A three-dimensional hydrogeologic-framework model of the region was initially constructed to provide a conceptual model of the geometry, composition, and hydraulic properties of the materials that control the regional ground-water flow system. This framework was resampled at the scale of the flow model to define the hydrogeologic units present in each of the 15 flow-model layers. In addition, there are non-traditional types of geologic data in the hydrogeologic-framework model that are used during flow-model calibration. For each hydrogeologic unit, the spatial distribution of geologic features important to the hydrologic system is defined. The volumetric cells can be populated by various hydrogeologic data such as the hydrogeologic unit, lithology, hydraulic conductivity, faulting, tectonic features, stratigraphic or lithologic facies, porosity, and derivative data calculated from these attributes. The approach for using this arsenal of geologic data is dependent on utilizing parameter-estimation techniques available within MODFLOW-2000. The principle of parsimony is …

A letter report issued by the General Accounting Office with an abstract that begins "The Nuclear Regulatory Commission (NRC) has decided to move its technical training center from Chattanooga, Tennessee, to near its headquarters in Rockville, Maryland. The relocation is intended to improve the effectiveness and efficiency of the agency's operations. The center provides diverse training curricula on such topics as nuclear power plant technology augmented by training on simulators, risk assessment, radiation protection, and regulatory skills. NRC used a reasonable methodology to determine the costs of relocating its facility. It considered costs related to staff salaries, travel costs for center participants, and lease payments. However, NRC used several assumptions that, if changed, would affect the cost of the move. For example, a change in the number of staff who would relocate would have an impact on costs. According to NRC, the objective of the move was not to minimize the cost of operating the center but rather to improve the effectiveness and efficiency of the agency's operations. NRC believes that the move would yield many benefits, including greater access to training facilities by its headquarters staff and frequent use of simulators in investigations. NRC needs to resolve several issues …

Taxes have been a major focus of congressional attention during the first half of 2000. In part, Congress has returned to many of the issues it addressed last year. In August, 1999, Congress passed a set of tax cuts with the Taxpayer Refund and Relief Act (H.R. 2488; TRRA). However, President Clinton vetoed the bill, arguing that the cuts were too large (an estimated $792 billion over 10 years), would drain funds from Social Security surpluses, and would force reductions in domestic spending. Early in 2000, Congress signaled its intention of revisiting tax cuts with passage on April 13 of a fiscal year (FY) 2001 budget resolution (H.Con.Res. 290) calling for a 5-year tax cut of $175 billion.
