COMPUTERIZED CONTROL OF NUCLEAR MATERIALS FOR URANIUM RESIDUE REPROCESSING

During the manufacture of uranium fuel cores, many diverse types of residues are generated. The uranium values of these residues must be recovered and returned to the main uranium processing stream. Normally, these uranium values are returned to the solvent purification step; however, most of the residues require several pretreatment operations before they become amenable to the HNOs-Tri Butyl Phosphate Extraction Process. The number and types of residues involved and the diverse pre- treatment operations required multiply nuclear materials control problems and create many scheduling problems in reintroducing the uranium into the main processing stream. Several Honeywell- 200 digital computer programs were therefore written and are being used to aid in the evaluation, scheduling and control of these residues. These programs, when completely linked, will eliminate many manual computations and clerical operations now required for: 1, Nuclear Materials control. 2. Evaluation and assignment of residues„ 3« Advanced production scheduling.
