Processing capacity of the Purex Plant
Discussions with Pile Technology personnel have indicated that instantaneous pile operating levels as high as 14,000 megawatts may be attained in approximately two years. Although not contemplated at the present time, further increases could conceivably be attained by modifying the KE and KW piles. If the above figure of 14,000 megawatts is adjusted for normal pile summer-winter operating level variation and the estimated operating efficiency of the piles, it appears that the ''year-around average'' pile operating level would be approximately 12,000 megawatts. If the uranium is discharged from the piles at the present integrated exposure rate of 600 megawatt-days/ton, an average of approximately 20 tons of uranium must be processed per day (7300 tons/year) through the separations facilities in the 200 Areas. Assuming an 80% operating efficiency for the separations plants the total instantaneous processing rate of the separations facilities must be approximately 25 tons of uranium per day. The instantaneous processing design capacity for the Redox Phase 2 Plant is 8.33 tons. This leaves approximately 16.7 tons of uranium to be processed in the Purex and Bismuth Phosphate Plants. Since it is considerably more costly to process uranium through the Bismuth Phosphate Plants it would be desirable to process the entire 16.7 tons U/day through the Purex facility. In this document the Purex Plant as presently designed is examined to determine the equipment modifications necessary to permit processing at instantaneous processing rates twice the nominal design rate of 8.33 tons/day.
