100 Areas Technical Activities Report - Engineering, April 1947

Description: This is the first of a series of monthly reports covering details of the work of the Engineering Group of the Pile Technology Section of the Technical Department. The monthly Slug Inspection Report is being discontinued as a separate document and is being incorporated in this group report. Included is work on corrosion and blistering; graphite expansion; and irradiation studies.

100 Areas technical activities report: Engineering, August 1947

Description: There were seven charges of metal inspected during the month for corrosion and blistering studies. There were no unusual cases of blistering noted and the corrosion rates were normal for this time of year. Borescopic examination of the graphite packing around the ``B`` Hole in the F Pile revealed that the graphite is no more severely cracked than in the D Pile when it was inspected about a year ago. Examination of the graphite at the downstream and of Tube 1385-D did not indicate that any damag… more

100 Areas technical activities report -- Engineering, July, 1947

Description: This monthly report covers activities for the production reactors. The 100 Area activities include: corrosion and blistering studies of slugs and flanges; study of the process tube leak at 105-D; graphite expansion studies which include galling of process tubes and stresses in biological shields; and irradiation studies.

100 Areas technical activities report: Engineering, June 1947

Description: There were no cases of unusual blistering of slugs being followed under Production Tests. Two normal production tubes were borescoped following trouble with discharge. In Tube 3188-D a distorted slug became stuck in the region of sharp curvature near the inner end of the rear gun barrel; this is the first time this phenomenon has occurred. Examination of irradiated slugs of rolled metal after normal exposure indicates that rolled material has no particular advantages over extruded material from… more

100 Areas technical activities report - physics, December 1946

Description: This report summarizes physics experiments carried out in different parts of the 100 area at Hanford during December, 1946. This included work on the D pile, F pile, and experiments aimed at studying the irradiation properties of graphite and metal samples exposed to different radiation environments. Pile tests included reactivity tests, calibrations of control rods, and power coefficient tests.

100 Areas Technical Activities Report - Physics, January 1947

Description: Four routine shutdowns were experienced during the month. A measurable amount of the excess reactivity held in the control rods at the first of the month has been lost in the decrease in the average accumulated exposure of all the metal in the pile. The vertical safety rod guides have been measured for vertical alignment by the Maintenance Dept. A definite pattern has been found in the misalignment of the guides. The horizontal rod thimbles were borrowed on January 2, 1947 to see if any leaks w… more

100 Areas technical activities report: Physics, March 1947

Description: U.M. Staebier reports from the pile areas. Foil tests were conducted at the B pile. A power coefficient test was performed at the D pile; special request materials and reactivity balance are also reported. The new No. 2 horizontal rod of the F pile has been slightly resized. Graphite temperature readings, thermal conductivity calculations, special request materials, and reactivity balance are also reported. General physics are considered. Production tests 105-85-P and 106-1-P are reported. Egg … more

The 1350 F stress-rupture properties of two wrought alloys and three cast alloys

Description: From Summary: "These properties compare favorably with those of the strongest similar alloys previously investigated. However, compared with a 60Cr-25Fe-15Mo alloy, the three cobalt-chronium-nickel cast alloys are inferior. A correlation of NACA and OSRD (Project NRC-8) data is presented, showing the variation of rupture strengths with temperature in the range of 1350^o to 2000^o for alloys."
