The Separations Technology Laboratory was requested to study what happens when a filtrate solution, which will be a F B-Line product, is neutralized with sodium hydroxide. The primary concern was the formation of solids that could cause damage in pump seals, resulting in their failure. The results of these experiments indicate that under process conditions, granular, crystalline sodium fluoride will be produced by rapid neutralization of the filtrate solution with 50% NaOH plus a 25 volume percent excess. Postprecipitation of sodium oxalate-sodium fluoride and its accumulation can occur over a three-week storage period of the neutralized filtrate. Such solids could pose operational problems from pump seal abrasion and potential failure caused by them.

A new glove-box system that was designed around a high-pressure tritium pump is described. The system incorporates new containment ideas such as ''burpler'' passive pressure controls, valves that can be turned from outside the box, inflatable door seals, ferro-fluidic motor-shaft seals, and rapid box-to-hood conversion during cryostaging. Currently under construction, the system will contain nine separate sections with automatic pressure-balancing and venting systems. 3 refs., 5 figs.
