Pile Engineering reports on: metal deformation studies, status of group I metal, flow laboratory activities, boroscope inspection details, pile control details, elimination of silica feed, controlled exposure temperature for graphite samples, naval fuel test channel, strength of masonite at elevated temperatures, carbon dioxide pile temperature, H pile graphite temperature, sampling of pile graphite, special pile motion measurements, pile expansion, far side restraining clamps, vortical thimble thermocouples, and boiling studies. The Physical Chemistry Group reports on: pile annealing studies, thermal annealing studies, empty process tube temperature, X- ray line broadening, X-ray diffraction studies, the CSF program, the WSF program, and higher temperature exposures.

Progress is reported by the Mechanical Development group and by the Plant Assistance group. The Mechanical Development group reports on the thimble removal program, special pile measurements and instruments, graphite sampling, and the ruptured slug problem. The Plant Assistance group reports on technical information on the B, D, F, and H piles, special request container slug, exposure of P-10 fuel slugs, slug corrosion studies, front tube corrosion, and flow laboratory experiments.

This is a progress report of the production reactors on the Hanford Reservation for the month of August 1950. This report takes each division (e.g. manufacturing, medical, accounting, occupational safety, security, reactor operations, etc.) of the site and summarizes its accomplishments and employee relations for that month.
