Cyclic Pressure Tests of Large Size Pressure Vessels

Description: This investigation into the plastic fatigue strength of large size pressure vessels is a part of a general research program on plastic fatigue problems in pressure vessels which is being carried out at several laboratories. While the overall program includes identical pairs of vessels fabricated from A-201, A-302, and T-1 steels, the work in progress concerns only the A-201 vessels. This report covers the progress in the period from 15 January 1960 to 15 February 1960.

Progress letter No. 11 for January 1, 1960 through January 31, 1960

Description: A stainless steel autoclave for superheated water corrosion test was installed and "conditioned". Tests were begun to investigate the feasibility of densifying slip cast stainless steel by means of liquid phase sintering. Attempts to prepare tubular fuel elements by vacuum forming were resumed. Although thick-walled vacuum formed casting have been sintered on the aluminum mandrels without cracking, this has not yet been accomplished with the think sections of interest.

Progress Report for Period Covering January 15, 1960 - February 15, 1960

Description: Thorium Procedure: As was mentioned in the last report, ammonium nitrate was substituted for ferric nitrate as a salting agent. Also, the acidity of the nitrate solution was reduced from 3.0 molar to 0.5 molar. the revised thorium procedure is described in the report. Radium Procedure: Work has ben initiated on the procedure of Petrow, Nietzel and DeSesa (Winchester Procedure) to determine if the procedure is suitable for very low level concentrations of radium.
