100 Areas technical activities report -- Physics, November 1946
This report divides the activities for November into three sections: D Pile; F Pile; and general physics. During November the D Pile was down twice for regularly scheduled shutdowns. Two scram occurred during the month, both of short duration. Five Special Request 15 tubes were discharged and recharged with Special Request 15. Some 13 inhour of reactivity were gained during the month. Vertical rod thimbles, 10 through 22, were tested. A Production Test was performed to determine the reactivity power coefficients of the F Pile at low power levels and with practically no xenon poison remaining. Additional experience in the use of temporary poison columns during an extended shutdown of the pile was obtained during the month. Four new bismuth columns were charged during the month and six tubes were charged with LiF. The F Pile had not yet returned to xenon equilibrium following the shutdown of November 27 at the end of the month, but conditions just prior to this shutdown indicate a loss of one inhour since October 31. Two sets of specimens were removed from the ``B`` Test Hole of the F Pile on November 4. Samples were also machined from graphite removed from the No. 9 …

100 Areas technical activities report -- Physics, October 1946
The D Pile was down five times for scheduled shutdowns. The fifth shutdown was of short duration for the purpose of discharging temporary ``P`` columns. Details of the shutdowns are given. Three new bismuth columns were established, Special Requests were charged into seven tubes and three Special Requests were discharged. Three tubes were charged with four-inch slugs. The power level of the F Pile has been corrected for the discrepancy noted last month. Material for irradiation under the Special Request program was charged into six tubes and the B experimental hole during the month. The effect of poison columns and rods on the temperature distribution of the pile was checked for the overall content of the pile. The F Pile gained two in hours in cold, clean reactivity during the month if allowance is made for xenon poison values corresponding to 190 MW for the beginning of the month and 200 MW at the end of the month. The graphite stringer removed from the ``D`` test hole of the D Pile on 3-12-46 was studied physical radiation effects.

100 Areas technical activities report -- Physics, October 1949
This report contains brief summaries of activities at the Hanford production reactors for the month of Oct. The activities for the Pile Physics Group are: (1) H Area start-up; (2) outlet temperature recording systems; (3) reactivity balance for each pile for this period. Activities for the Experimental Physics Group are: (1) graphite testing; (2) 305 testing -- P-slug standardization and graphite standards; (3) shielding. Also status is given on critical mass project.

100 Areas technical activities report - physics, September 1946
The Pine unit was down four times during the month. These were all regularly scheduled shutdowns. Times down vary from 16.9 hours to 19.2 hours. A total of 33.4 tons of metal was discharged. The galvano-meter chamber in experimental hole {open_quotes}A{close_quotes} was replaced. One Special Request was discharged and three tubes have been loaded with Special Request samples. A new bismuth column has been established. Some difficulty has been experienced with high temperatures of both tube exit water and graphite following startup. On one occasion the normal operating level was exceeded for a short period of time.

100-F area unit purge, May 3, 1945
This report discusses the pressure drop on the 100-F unit, as measured on the eight pressure drop tubes, which had increased to 24 lbs./in.{sup 2} above base by May 2. The unit was shut down on May 3 to purge with 50 ppm solids for 1.1 hr. and to take care of necessary maintenance work.
