During this period the B Pile operated at its assigned power level of 25 MW below rated level, except for 10 hours on January 5. The operating level of the D Pile remained at 25 MW below rating. The rate gain in excess reactivity during equilibrium operation has been about 1.8 inhours/day. On January 1, the power level of the F Pile was dropped to 25 MW below rating from its previous rated level. Rod A was in a favorable position to make a determination of the reactivity coefficients at the time. The data does indicate an upper limit of {minus}0.21 ih/MW for the metal coefficient. An overall coefficient of 0.20 ih/MW was obtained. The unit was shut down on January 3 for discharge of 129 tubes of metal. A summary of the present reactivity states of the B, D, and F Piles are given. Iron content of process water for the three piles is also given.

The B Pile operated 25 MW below rated power level without interruption during the week. The D Pile was shut down on January 29. During the shutdown 103 tubes were discharged. The shut down lasted for 15 hours. During operation after the shut down power was reduced to meet graphite temperature restrictions. The F Pile was run steadily throughout the week at 25 MW below rated level. Iron content in the process water averaged 0.015, 0.011 and 0.010 ppm at B, D, and F Areas, respectively. Examination of the slugs discharged from four corrosion tubes at F has been completed. A summary of conditions found in the vertical and horizontal aluminium thimbles at D and F during a recent inspection are given. Results are given on the graphite expansion problem.

100 Areas technical activities report: Engineering, August 1947

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 damage had been done by the leak in that tube. Forty one tubes have been charged in the F Pile on Production Test 105-90-P, ``Exposure of TX Metal Slugs.`` The routine job of taking vertical bowing measurements was turned over to the Instrument Department after working with them once in each Area. Installation of Van Stone test units was completed and a brief run was started. Van Stone flanges at both ends of 64 process tubes in both the B and F Piles were measured with a micrometer to determine the minimum amount of metal remaining.

100 Areas technical activities report: Engineering, June 1947

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 the standpoint of blistering. However, no extensively blistered pieces were found in either the rolled metal are being held for more extended exposure. Inspection of a large number of Van Stone flanges in the D and F Piles has confirmed that the inlet flanges are in generally good condition but that the rear Van Stone flanges of tubes in the 0.140-inch orifice sone of both piles were badly corroded and generally contained deep pits that extended about half-way through the flange. The Van Stone test units are to be installed unshielded in the risor room at the rear of the D Pile, since the shielding required in the X Sample Room exceeded the allowable floor loading. Recent experimental observations indicate that solid …

100 Areas Technical Activities Report - Physics, January 1947

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 were present. No leaks were observed but No. 2 Rod and No. 8 Rod had heavy gouge marks along the longitudinal axes. Several thimbles contained white corrosion. During the month two new bismuth tubes were established, 2871-D and 2877-D. This now gives the desired pattern of ten bismuth tubes.
