Aquifer tests near the Idaho Falls Foothills, Idaho

Description: Ground water pumping tests were performed in two wells located in the foothills east of Idaho Falls to determine the aquifer characteristics at these locations. These data were used to differentiate this aquifer from the Snake River Plain aquifer. The wells were pumped at rates of 11 and 14 gallons per minute with 0.03 and 0.04 ft of drawdown measured in the pumping wells. The transmissivity is estimated to be 525,000 gpd/ft and 450,000 gpd/ft, respectively. The hydraulic conductivity is 925 ft… more

Review of the margins for ASME code fatigue design curve - effects of surface roughness and material variability.

Description: The ASME Boiler and Pressure Vessel Code provides rules for the construction of nuclear power plant components. The Code specifies fatigue design curves for structural materials. However, the effects of light water reactor (LWR) coolant environments are not explicitly addressed by the Code design curves. Existing fatigue strain-vs.-life ({var_epsilon}-N) data illustrate potentially significant effects of LWR coolant environments on the fatigue resistance of pressure vessel and piping steels. Th… more

MELT RATE FURNACE TESTING FOR SLUDGE BATCH 5 FRIT OPTIMIZATION

Description: Savannah River National Laboratory (SRNL) was requested to provide the Defense Waste Processing Facility (DWPF) with a frit composition for Sludge Batch 5 (SB5) to optimize processing. A series of experiments were designed for testing in the Melt Rate Furnace (MRF). This dry fed tool can be used to quickly determine relative melt rates for a large number of candidate frit compositions and lead to a selection for further testing. Simulated Sludge Receipt and Adjustment Tank (SRAT) product was ma… more

Scalable File Systems for High Performance Computing Final Report

Description: Simulations of mode I interlaminar fracture toughness tests of a carbon-reinforced composite material (BMS 8-212) were conducted with LSDYNA. The fracture toughness tests were performed by U.C. Berkeley. The simulations were performed to investigate the validity and practicality of employing decohesive elements to represent interlaminar bond failures that are prevalent in carbon-fiber composite structure penetration events. The simulations employed a decohesive element formulation that was veri… more

Atomic coherence created by a pulsed dye laser

Description: Level population as a function of laser pulse envelope area for an atom which could be approximated as a two level system was measured. An ideal two-level system under the action of an oscillating force is one of a few quantum mechanical systems for which the time-dependent Schroedinger equation can be solved exactly. The solution predicts that the population of the upper state, for a system which was entirely in the lower state at t = 0, varies as sin/sup 2/A, where A = ..integral../sub 0//sup… more

Primary system temperature limits and transient mitigation

Description: Results of a study to determine the limiting temperature conditions in a large reactor system are presented. The study considers a sodium-cooled breeder reactor system having a loop-type primary system configuration. A temperature range of 930 to 1050/sup 0/F in reactor outlet temperature is covered. Significant findings were that the use of the materials for the 930/sup 0/F reference design, i.e., a core material of 20% cold-worked 316 stainless steel, a primary piping material of 316SS, and a… more

Small, octopole-stabilized tandem mirror reactor

Description: It is shown that the use of octopole stabilization in a tandem mirror allows a large reduction in end-cell length. A novel feature of the method proposed in this report is the placement of the minimum IBI region coonsiderably off axis, thus rendering the core plasma more axisymmetric. The region from the core to the field minimum is bridged by a mirror-confined hot-electron mantle. Low ..beta.., ideal magnetohydrodynamic stability, as evaluated with the interchange criterion, yields an upper li… more

Synchronous particle and bucket dynamics

Description: In accelerator theory of particle longitudinal motion, a classical definition if a synchronous particle (synchronous energy, synchronous phase, synchronous orbit) assumes that there is a one-to-one relationship of the accelerator electrical field. In practice, that relationship may not be sustained because of errors in the magnetic field, radio frequency, or because sometimes we do not want to keep that relationship for some reason. In this report we formulate the concept of adiabatic equilibri… more
