TMIST-2 Transport Test
Abstract
In anticipation of the TMIST-2 experiment in the Advanced Test Reactor, there was a need to determine if the tritium that is expected to be observed at the outlet of the experiment would be seen or if it may be lost on its way from the experiment in the core to the measurement station. To assist in resolving that issue, a bench-scale experiment was conducted in the Idaho National Laboratory’s Safety and Tritium Applied Research (STAR) facility using deuterium and a mass spectrometer in lieu of tritium with ion chambers, bubblers, and scintillation counting. The experiment replicated the concentration of the hydrogen isotope, the flow rates anticipated, and the residence times. It was found that there was initial uptake on tubing walls, presumably due to oxidation of the hydrogen isotopes to water and adsorption or isotopic exchange, but that saturates relatively quickly, and once saturated, the concentration of deuterium at the outlet of the tubing system was essentially the same as it was at the experiment inlet under the conditions modeled in the experiment.

As prescribed in the Pahute Mesa Corrective Action Investigation Plan (CAIP) (DOE/NV, 1999) and Appendix VI of the Federal Facility Agreement and Consent Order (FFACO) (1996, as amended February 2008), the ultimate goal of transport analysis is to develop stochastic predictions of a contaminant boundary at a specified level of uncertainty. However, because of the significant uncertainty of the model results, the primary goal of this report was modified through mutual agreement between the DOE and the State of Nevada to assess the primary model components that contribute to this uncertainty and to postpone defining the contaminant boundary until additionalmore »

ACTIVATION AND TRANSPORT OF LONG LIVED CORROSION PRODUCTS. CORE I, SEED 2. EFPH 718.7 EFPH 2147.0. Test Results T-641107-A
In ganeral the activity levels of the various nuclides Co/sup 6//sup 0/ Co/sup 5//sup 8/ Hf/sup 1//sup 8//sup 1/, Fe/sup 5//sup 9/, Zr/sup 9//sup 5/, Mn/ sup 5//sup 4/, W/sup 1/ /sup 8//sup 1/, Cr/sup 5//sup 1/. increased in the interval between the test performances. This was particularly true of the Fe/sup 5//sup 9/ and Mn/sup 5//sup 4/ nuclides where very large increases were noted. Zr/sup 9//sup 5/ and W/sup 1//sup 8//sup 1/ were both undetectable in the two performances. During the interval the system was operated with no purification, and it is likely that the increase in the activitymore » -
Guidelines for selecting codes for ground-water transport modeling of low-level waste burial sites. Volume 2. Special test cases
This document was written for the National Low-Level Waste Management Program to provide guidance for managers and site operators who need to select ground-water transport codes for assessing shallow-land burial site performance. The guidance given in this report also serves the needs of applications-oriented users who work under the direction of a manager or site operator. The guidelines are published in two volumes designed to support the needs of users having different technical backgrounds. An executive summary, published separately, gives managers and site operators an overview of the main guideline report. Volume 1, titled ''Guideline Approach,'' consists of Chapters 1more » -
Pneumatic transport of coal in a variable inclined test loop. Quarterly report 2. [Evaluation of cocurrent upflow and downflow of solid-gas mixtures in inclined pipelines]
Despite many frequent references, in the literature on pneumatic transport, to the advisability of employing diagonals rather than vertical runs, research and development in the area of inclined flow are very limited. Another unexplored area in pneumatic transport is the cocurrent downflows of solids and gas, either in vertical or inclined pipes. Flow tests with Virginia Coal were conducted in the Variable Inclined Test Loop, to provide a data base for the evaluation of cocurrent upflow and downflow of solid-gas mixtures in inclined pipelines. Preliminary results indicated that: (a) the classic minimum pressure-drop with gas velocity was present for verticalmore » -
Measurements of radial profiles of He sup 2+ transport coefficients on TFTR (Tokamak Fusion Test Reactor)
Measurements of the spatial structure of the transport coefficients of He{sup 2+} on the Tokamak Fusion Test Reactor is reported. He{sup 2+} profiles were measured using charge exchange spectroscopy after a helium puff into corotating L-mode plasmas. Modelling shows that the He{sup 2+} diffusivity is about 10 m{sup 2}/s near the plasma edge and drops to below 1 m{sup 2}/s inside of the q = 1 surface. The convective velocity ranges from 1--3 m/s near q = 1 to 20--40 m/s near the edge. The helium diffusivity is on the order of the ion momentum and thermal diffusivity and ismore »
