Corrosion of structural materials by lead-based reactor coolants. (open access)

Corrosion of structural materials by lead-based reactor coolants.

Advanced nuclear reactor design has, in recent years, focused increasingly on the use of heavy-liquid-metal coolants, such as lead and lead-bismuth eutectic. Similarly, programs on accelerator-based transmutation systems have also considered the use of such coolants. Russian experience with heavy-metal coolants for nuclear reactors has lent credence to the validity of this approach. Of significant concern is the compatibility of structural materials with these coolants. We have used a thermal convection-based test method to allow exposure of candidate materials to molten lead and lead-bismuth flowing under a temperature gradient. The gradient was deemed essential in evaluating the behavior of the test materials in that should preferential dissolution of components of the test material occur we would expect dissolution in the hotter regions and deposition in the colder regions, thus promoting material transport. Results from the interactions of a Si-rich mild steel alloy, AISI S5, and a ferritic-martensitic stainless steel, HT-9, with the molten lead-bismuth are presented.

Flux Consumption Optimization and the Achievement of 1MA Discharge on NSTX (open access)

Flux Consumption Optimization and the Achievement of 1MA Discharge on NSTX

The spherical tokamak (ST), because of its slender central column, has very limited volt-second capability relative to a standard aspect ratio tokamak of similar plasma cross-section. Recent experiments on the National Spherical Torus Experiment (NSTX) have begun to quantify and optimize the ohmic current drive efficiency in a MA-class ST device. Sustainable ramp-rates in excess of 5MA/sec during the current rise phase have been achieved on NSTX, while faster ramps generate significant MHD activity. Discharges with IP exceeding 1MA have been achieved in NSTX with nominal parameters: aspect ratio A=1.3-1.4, elongation k=2-2.2, triangularity d=0.4, internal inductance li=0.6, and Ejima coefficient CE =0.35. Flux consumption efficiency results, performance improvements associated with first boronization, and comparisons to neo-classical resistivity are described.

Forest Service: Consolidation of the Rocky Mountain Forest and Range Experiment Station With the Intermountain Research Station (open access)

Forest Service: Consolidation of the Rocky Mountain Forest and Range Experiment Station With the Intermountain Research Station

Correspondence issued by the General Accounting Office with an abstract that begins "The Forest Service consolidated its Rocky Mountain Forest and Range Experiment Station with its Intermountain Research Station. The resulting consolidated station was renamed the Rocky Mountain Research Station and was relocated to Fort Collins, Colorado. The Forest Service originally proposed consolidating the two stations in 1992 but delayed taking any action until it completed its reorganizational assessment in May 1997. The Forest Service cut 18 managerial and administrative staff positions during the consolidation. The positions that were eliminated were either transferred to other Forest Service units or were vacated through retirement or employee buyouts. Since 1992, the research funding available to the merged station has remained relatively constant, about 15 percent of the Forest Service's budget for research stations, and the number of employees has remained relatively stable."

Hazard Evaluation for the Saltwell Chempump and a Saltwell Centrifugal Pump Design using Service Water for Lubrication and Cooling

This report documents results of a preliminary hazard analysis (PHA) covering the existing Crane Chempump and the new salt well pumping design. Three hazardous conditions were identified for the Chempump and ten hazardous conditions were identified for the new salt well pump design. This report also presents the results of the control decision/allocation process. A backflow preventer and associated limiting condition for operation were assigned to one hazardous condition with the new design.

High Harmonic Fast Wave Heating Experiments on NSTX (open access)

High Harmonic Fast Wave Heating Experiments on NSTX

A radio frequency (rf) system has been installed on the National Spherical Torus Experiment (NSTX) with the aim of heating the plasma and driving plasma current. The system consists of six rf transmitters, a twelve element antenna and associated transmission line components to distribute and couple the power from the transmitters to the antenna elements in a fashion to allow control of the antenna toroidal wavenumber spectrum. To date, power levels up to 3.85 MW have been applied to the NSTX plasmas. The frequency and spectrum of the rf waves has been selected to heat electrons via Landau damping and transit time magnetic pumping. The electron temperature has been observed to increase from 400 to 900 eV with little change in plasma density resulting in a plasma stored energy of 59 kJ and a toroidal beta, bT , =10% and bn = 2.7.

Lessons Learned from Decontamination Experiences (open access)

Lessons Learned from Decontamination Experiences

This interim report describes a DOE project currently underway to establish what is known about decontamination of buildings and people and the procedures and protocols used to determine when and how people or buildings are considered ''clean'' following decontamination. To fulfill this objective, the study systematically examined reported decontamination experiences to determine what procedures and protocols are currently employed for decontamination, the timeframe involved to initiate and complete the decontamination process, how the contaminants were identified, the problems encountered during the decontamination process, how response efforts of agencies were coordinated, and the perceived social psychological effects on people who were decontaminated or who participated in the decontamination process. Findings and recommendations from the study are intended to aid decision-making and to improve the basis for determining appropriate decontamination protocols for recovery planners and policy makers for responding to chemical and biological events.

A matrix-matrix multiplication approach to the automatic differentiation and parallelization of straight-line codes. (open access)

A matrix-matrix multiplication approach to the automatic differentiation and parallelization of straight-line codes.

A Straight-line code, which consists of assignment, addition, and multiplication statements is an abstraction of a serial computer program to compute a function with n inputs. Given a serial straight-line code with N statements, the authors derive an algorithm that automatically evaluates not only the function but also its first-order derivatives with respect to the n inputs on a parallel computer. The basic idea of the algorithm is to marry automatic computation of derivatives with automatic parallelization of serial programs. The algorithm requires O(M{sub N} log of N) scalar operations, where O(M{sub N}) is the time complexity of a parallel multiplication of two dense N x N matrices and it represents a measure of the complexity of the straight-line code. Although it can be exponential in N in the worse case, it tends to be only polynomial in N for many important problems.
