Operational Problems with Uranium Pots Due to Helium Blanketing

Stephanie G. Smith、Ronald E. Johnson、J. M. Miller1995-10-01Fusion Technology

Extensive experience with the refilling of the Amersham Mk IV 1.85 PBq uranium pots has shown that helium-3 resident in the uranium matrix causes “blanketing” of the metal surface and subsequent operational problems. This paper reviews the operational procedures and results observed at Ontario Hydro’s dispensing facil…

Extrapolated partial molar densities of SO 3 , P 2 O 5 , and other oxides in silicate melts

P. H. Warren1995-10-01American Mineralogist

Partial molar densities of oxides in natural silicate melts can be estimated to useful precision by exploiting their strong correlation with densities of the corresponding solid oxides, reflecting the close structural similarity between silicate solids and silicate melts. Using this extrapolation method, partial molar…

Design of a Second Generation Secondary Enclosure clean-Up System

A.G. Heics、W.T. Shmayda1995-10-01Fusion Technology

An upgraded version of a metal hydride based clean-up systema for tritium gloveboxes has been recently designed. An earlier version of a prototypical, recirculating system has been under evaluation in tritium service at OHT for nearly 2 years. A metal getter alloy, Zr2Fe, is used to remove tritium and trace impurities…

In-Bed Accountability of Tritium in Production Scale Metal Hydride Storage Beds

J. E. Klein1995-10-01Fusion Technology

An “in-bed accountability” (IBA) flowing gas calorimetric measurement method has been developed and implemented to eliminate the need to remove tritium from production scale metal hydride storage beds for inventory measurement purposes. Six-point tritium IBA calibration curves have been completed for two, 390 gram tri…
