Causes of damage to tube 1794-C

Description: Tube 1794-C was removed from the pile as a leaker on July 15, 1954. The tube had been in-pile since startup and had contained a charge of 32 ``C`` metal slugs just prior to discharge. The tube was slit and examined at the 105-DR underwater viewing facility by Pile Coolant Studies tube examination personnel. A report is made of the examination of tube 1794-C which revealed areas of severe pitting damage. This damage was apparently caused by cocked slugs abrading the tube. The attack was great en… more

Effect of Jet-Nozzle-Expansion Ratio on Drag of Parabolic Afterbodies

Description: The interaction of the flow from one convergent and two convergent-divergent nozzles on parabolic afterbodies was studied at free-stream Mach numbers of 2.0, 1.6, and 0.6 over a range of jet pressure ratio. The influence of the jet on boattail and base drag was very pronounced. Study of the total external afterbody drag values at supersonic speeds indicated that, over most of the high-pressure-ratio range, increasing the nozzle design expansion ratio increased the drag even though the boattail … more

Effect of Molten Sodium on Thermal Insulation Specimens

Description: Every type of thermal insulating material tested showed attack in varying degeces. Many specimens which had been cured at 1000 deg F, with no color change, did show drastic changes at 950 deg F due to the action of sodium. The materials showing the least disintegration and greatest preservation of mechanical properties were Superex paste and Eagle-Picher mineral wool. The uncured Superex Block did not hold up as well as Superax paste, presumably due to the presence of water of crystallization; … more
