Hot Semiworks summary: Run PX-13
This report provides a summary of the Hot Semiworks Unit Run PX-13. During Run PX-12 acceptable HA Column decontamination was demonstrated; however, generally under unstable column operating conditions. The principal objectives of PX-13 were: To duplicate the high PX-12 decontamination factors under stable HA Column operating conditions; to study the effects of fresh solvent, IO Column CP carbonate washed solvent, and IO Column Technical grade carbonate washed solvent on A Column decontamination factors; to study the effect of increasing the HA, HC, and IA uranium processing rates to 14 tons per day (plant equivalent); to study the effect of an intermediate 2A Column scrub on UX{sub 1} decontamination; and to study the effect of sulfamic acid addition to the HAF, HAS, IAF, and IAS and NaNO{sub 2} omission from the HAF and IAF.

EXAMINATION OF TITANIUM PULSE FEEDER DIAPHRAGM FAILURE
A Ti pulse feeder diaphragm failed by cracking after 450 hr service in the Homogeneous Reactor Test mock-up. The diaphragm, which was made of MST Grade III Ti, was vibrated at 78 cpm at 40 to 50 deg C. One side of the diaphragnn was exposed to demineralized H/sub 2/O and the other side was exposed to 10g U/l UO/ sub 2/SO/sub 4/ solution. The main corrosion product was TiO/sub 2/. (W.L.H.)

METALLOGRAPHIC EXAMINATION OF HIGH VELOCITY HEAT EXCHANGER (SHE NO.1)
Judging from the condition of the tube walls, this heat exchanger was close to failure. The depth of intergranular attack on the inner NaK surface (0.003 in.) and the depth of subsurface voids on the fuel side (0.007 in.) were more than half the wall thickness and these measurements were only from a few scattered specimens and on one plane per specimen. The grain size was much larger in the hot end than in the cold end of the heat exchanger. This increased grain size in the hot end could be attributed to the absence of precipitate and greater triaxial stresses due to thermal expansion and a thermal differential across the tube wall. Also, the strain anneal effect due to the thermal cycling during operation at a specific temperature would accelerate grain growth. These stress conditions and the resulting change in microstructures are directly related to the operating temperature at the hot end. The greater depth of corrosion at the hot end could also be due to a greater stressed condition or a corrosion fatigue. Mass transfer was present where the NaK entered the heat exchanger, but this deposition was influenced greatly by flow against the tube walls. The maximum …

THE DETERMINATION OF NIOBIUM IN URANIUM-NIOBIUM ALLOYS
Niobium is determined as the peroxy complex in concentrated sulfuric acid by photometric measurement at 360 m mu . Uranium interference is cancelled by using a solution of the sample for reference in the photometric measurement. The method covers the determination of niobium in uranium --niobium alloys made from pure melting stock. Molybdenum interferes and must be removed if present. Zirconium does not interfere. The calibration curve covers a concentration range from 0.2 to 5.0 mg. (auth)
