The loading on the primary transformers which step down the 230 kv transmission voltage to a distribution voltage of 13.8 kv, at 100-B-C, 100-D-DR, 100-F, and 100-H Areas will be increased by the synchronous motors now being installed in those areas under Project CG-558. This report summarizes: The changes in electric loads (both kv and power factor) which will result when the new motors are placed in service and certain older motors are withdrawn from service. Electric loads are tabulated in section 4.0 for each area for present conditions, the planned changes and the post-CG-558 conditions. The reduction of distribution voltage during the starting of individual 4500 hp synchronous motors. Since the synchronous motors will be started across the line as induction motors, the starting current will be high, and at a low power factor. Voltage drops are calculated for the starting of a synchronous motor, with one and then with two transformer banks paralleled. The current-interrupting capacity of switchgear vs. the maximum short-circuit current which could occur with separate transformers and with two primary transformers in parallel.

The Bevatron is still undergoing a process of gradual improvement to increase both the magnitude of the beam and the reliability. The operating conditions for optimum adjustment at the present stage of development are summarized.

This report discusses the use of solvent extraction techniques at HAPO for separating plutonium from uranium and fission products which is rather expensive. This is in part due to solvent, chemical and process steam costs and in part to the need for complicated equipment to handle the process. It is felt that the use of ion exchange resin techniques might be economically attractive both as to lowered chemical costs and equipment simplification. Also, the decontamination achieved by solvent extraction is at time marginal. Changing to another process following partial decontamination by solvent offers the possibility of greater over-all DF`s.

Separan is a now water plant coagulant chemical which was submitted to the Process Sub-Section for evaluation in late 1954. Beaker tents were run which showed the material to be potentially valuable in modern water filter plants, but thorough evaluation was impossible because proper testing facilities were not available. Since August 1955, Process Sub-Section has operated an experimental filter plant which has shown promise as an evaluation tool. Consequently, as the facility appeared to be adequate for testing Separan, a trial run was made. The results have been so promising that an interim report was thought desirable. The results of our primary tests follow.
