Abstract

This work was performed at the Portsmouth Gaseous Diffusion Plant where hydrogen fluoride is produced upon the hydrolysis of UF{sub 6}. This poses a problem for in this setting and a method for determining the mole percent concentration was desired. HF has been considered to be a non-ideal gas for many years. D. F. Smith utilized complex equations in his HF studies in the 1950s. We have evaluated HF behavior as a function of pressure from three different perspectives. (1) Absorbance at 3877 cm{sup -1} as a function of pressure for 100% HF. (2) Absorbance at 3877 cm{sup -1} as a function of increasing partial pressure HF. Total pressure = 300 mm HgA maintained with nitrogen. (3) Absorbance at 3877 cm{sup -1} for constant partial pressure HF. Total pressure is increased to greater than 800 mm HgA with nitrogen. These experiments have shown that at partial pressures up to 35mm HgA, HIF follows the ideal gas law. The absorbance at 3877 cm{sup -1} can be quantitatively analyzed via infrared methods.

Neutron experiments at Portsmouth for measuring flow and {sup 235}U content in UF{sub 6} gas

Technical Report Stromswold, D; Reeder, P; Peurrung, A

The Portsmouth Gaseous Diffusion Plant produces enriched uranium for use in commercial power reactors. The plant also aids disposal of excess high-enrichment uranium (HEU) by blending it with lower-enrichment material. Experiments were conducted to test two neutron-based methods for monitoring the down-blending of HEU. Results of the initial experiments showed that gas (on-off) could be detected, but that additional tests and data are needed to quantify the flow velocity and {sup 235}U content. The experiments used a {sup 252}Cf neutron source to induce fission in a small fraction of the {sup 235}U contained in the UF{sub 6} gas. The firstmore »« less

VAPOUR-PRESSURES OF NpF$sub 6$ AND PuF$sub 6$ THERMO-DYNAMIC CALCULATIONS WITH UF$sub 6$, NpF$sub 6$ AND PuF$sub 6$

Journal Article Weinstock, B; Weaver, E; Malm, J - J. Inorg. & Nuclear Chem.

The vapor pressures of NpF/sub 6/ and BuF/sub 6/ were measured from 0 to 77 deg C with a quartz sickle gage. The data were fitted to interpolation formulas from which the triple points. 55.10 deg C,758.0 mm Hg for NpF/sub 6/ and 51.59 deg C. 533.0 mm Hg for BuF/sub 6/, and boiling points, 55.18 deg C for NpF/sub 6/ and 62.16'C for BuF/sub 6/, wens calculated. The derived heat and entropy of fusion for NpF/sub 6/ and PuF/sub 6/ are 4198 and 4456 cal mole/sup -1/ and 12.79 and 13.72 cal mole/sup -1/ deg/sup -1/. respectively. Upon comparisonmore »« less

Hydrofluoric Acid Corrosion Study of High-Alloy Materials

Technical Report Osborne, P

A corrosion study involving high-alloy materials and concentrated hydrofluoric acid (HF) was conducted in support of the Molten Salt Reactor Experiment Conversion Project (CP). The purpose of the test was to obtain a greater understanding of the corrosion rates of materials of construction currently used in the CP vs those of proposed replacement parts. Results of the study will help formulate a change-out schedule for CP parts. The CP will convert slightly less than 40 kg of {sup 233}U from a gas (UF{sub 6}) sorbed on sodium fluoride pellets to a more stable oxide (U{sub 3}O{sub 8}). One by-product ofmore »« less

THE ESTIMATION OF HYDROGEN FLUORIDE IN MIXED GAS SYSTEMS BY INFRA-RED SPECTROSCOPY

Technical Report Deane, A

>The variation of the infrared absorption near 2.5 microns of hydrogen fluoride was studied for the systems HF, HF/N/sub 2/, HF/Ar, HF/N/sub 2//Ar, HF/H/ sub 2/O/N/sub 2/, HF/UF/sub 6/, and HF/UF/sub 6//N/sub 2/ at both 20 tained C and 60 tained C. Pressure broadening coefficients for many of these systems were derived but the room temperature results from the last system could not be simply expressed; an empirical relation for the broadening coefficient is given for UF/sub 6/ at 60 tained C. In general the results confirmed the earlier studies at higher temperatures by Smith. Both handling and spectroscopic techniquesmore »« less
Low temperature cold trapping of uranium hexafluoride containing hydrogen fluoride

Technical Report Hobbs, W; Barber, E; Jones, C

The use of a freezer-sublimer system operating at low desublimation pressures to replace 10-in. nuclearly safe cold traps for low assay (<5% U-235) uranium hexafluoride (UF{sub 6}) would significantly simplify operations and is economically attractive provided the nuclear safety of the system can be assured. A major requirement of such assurance is the availability of conditions guaranteeing that the nuclear safety design criterion, which requires that the H/U atomic ratio in the condensate in the freezer-sublimer always be less than 0.33 for assays up to 5%, will never be violated. A general vapor pressure equation giving the vapor pressure ofmore »« less
