A total of 70 batches was started in the Canyon Buildings, 69 were processed through t h e Concentration Buildings, and 77 were conpleted through the Isolation Building. The machicing yield was 78.0 percent, The average purity of com7lsted batches The electrical peak demand for the month was 72,700 KW, slightly higher than seasonal expectations. A critical power condition, Grade 2, the first complete loss of power occurred on June 6, 1950 due t o a fault on t h e newly energized Coulee line, caushg a complete loss of 7ouer for three minutes.

However, increased graphite temperatures i n the H-10 region increase the incentive for early removal of the vertical thimbles from the Hpile.

It was also established tn at the critical mass increases with increesing temperatme of t h e solutions. Vertical bowing measurements of the top c ez tr al tubes at the E and D piles during the past month give further evidence that as light annealing of previous expansion of the graphite near the front face i s occurring with t h e 100 percent carbon dioxide atmosphere. meesurements at the H pile indicate that significant vertical expansion of the filler blocks i s occurring.
