FFTF auxiliary system testing program: results and overview (posters)

The most important aspects of the Auxiliary System Testing Program to the overall startup of FFTF were in the areas of integrated testing of inerted cells, integrated leak rate testing of the containment building and testing of the waste gas processing systems for effluent cover gas and effluent cell atmosphere gases. The basic test methods and test results for these areas of the FFTF startup program are presented.

Analysis of binary vapor turbines

The effect the binary mixture has on the turbine is examined in terms of design and cost. Several flow theories for turbines and turbine blading are reviewed. The similarity method, which uses dimensionless parameters, is used in determining rotative speeds and diameters for a variety of inlet temperatures and exit pressures. It is shown that the ratio of exit to inlet specific volume for each component in the mixture is the same for each specie. The specific volume ratio constraints are combin… more

Deactivation and cleanout of the 308 Fuels Laboratory and the 232-Z Incinerator at the Hanford site

This paper describes the deactivation and source term reduction activities conducted over the recent past in two plutonium-contaminated Hanford Site buildings: the 308 Fuels Development Laboratory and the 232-Z Incinerator. Both of these facilities belong to the U.S. Department of Energy, and the projects are unique success stories carried out in direct support of EM-60 functions and requirements. In both cases the buildings, for different reasons, contained unacceptable amounts of plutonium, a… more

Fast Flux Test Facility acceptance test program and early results

At the present time, approximately 65% of the Phase 1 and 2 tests have been completed. The major systems which have been tested and are now operational to support sodium fill are summarized. On July 2, 1978 the first secondary loop was filled with sodium and pony motor flow initiated on July 3. Sodium sampling and cold trapping procedures were started immediately thereafter and are proceeding well. The preoperational Integrated Leak Rate Test of the containment building was satisfactorily compl… more

Integrated leak rate testing of the fast flux test facility reactor containment building

The initial Integrated Leak Rate Test (ILRT) of the Fast Flux Test Facility containment building was performed from May 27 to June 2, 1978. The test was conducted in air with systems vented and with the containment recirculating coolers in operation. 10 psig and 5 psig tests were run using the absolute pressure test method. The measured leakage rates were .033% Vol/24 hr. and -.0015% Vol/24 hrs. respectively. Subsequent verification tests at both 10 psig and 5 psig proved that the test equipmen… more

Comparative Experimental Study of X-Ray Absorption Spectroscopy and Electron Energy Loss Spectroscopy on Passivated U Surfaces

X-ray absorption spectroscopy and electron energy loss spectroscopy are complementary analytical techniques on energy and spatial resolution. These techniques are based on the same fundamental physical process of core excitation with either an incident photon or incident electron. In the proper experimental configuration the electron and photon inelastic scattering amplitudes are comparable and thus the x-ray and electron absorption edges look identical. We have applied these two complementary … more

Grain Size Effect on the Microhardness of BCC Metal Vapor Deposits

The physical vapor deposition methods of evaporation and sputtering are used to prepare foils of the body-centered-cubic metals, vanadium and tantalum. A two-fold increase in the micro-hardness is measured as the grain size decreases to the sub-micron scale. The micro-hardness of vanadium increases to 2.7 GPa and for tantalum to 2.9 GPa.

Utilizing Nano-focussed Bremstrahlung Isochromat Spectroscopy (nBIS) to Determine the Unoccupied Electronic Structure of Pu

Understanding the behavior of 5f electrons remains an unrealized ambition of condensed matter physics [1,2]. Recently, there has been a large amount of interest in the actinides, particularly plutonium, driven by the complex and intriguing behavior of Pu and several of its compounds [3-5]. This has prompted both theoretical and experimental investigations of 5f metals and compounds. Of the different allotropes of Pu, the d-phase is of particular interest because of the high symmetry crystal str… more

Experimental Benchmarking of Pu Electronic Structure

The standard method to determine the band structure of a condensed phase material is to (1) obtain a single crystal with a well defined surface and (2) map the bands with angle resolved photoelectron spectroscopy (occupied or valence bands) and inverse photoelectron spectroscopy (unoccupied or conduction bands). Unfortunately, in the case of Pu, the single crystals of Pu are either nonexistent, very small and/or having poorly defined surfaces. Furthermore, effects such as electron correlation a… more
