A meeting of the Thorium Working Committee was held at FMPC on September 20, 1955. The current status of the thorium production program was discussed and a limited development and evaluation program was outlined which it is felt will (1) clear up some of the more important question marks in thorium metal quality and (2) develop a more satisfactory method for processing solid metal scrap. The basic parts of this immediate program are (1) SRL would evaluate ingot sections of as-cast double arc-melted virgin metal in order to classify typical ingot defects and determine their frequency of occurrence; (2) Du Pont would request for evaluation purposes ingot sections from typical recycle ingots which incorporated vacuum-induction melting for the consolidation of recycle metal in the form of consumable electrodes for arc-melting; (3) after completion of item (2), du Pont would then request approximately 200 slugs, made from suitably processed recycle metal, which would be used for canning and steam autoclave tests. This program should lead to definite specifications (and/or classifications) for ingots to be stockpiled for future AEC use.
