CHAPTER IV, SECTION 2 expendable buildings or were set up without housing. Figure 4-20 indicates the building used at Nan to honse the power and distillation plant. _The following power plants were expended during test operations: Tare 500 Charhe 500 Dog 500 rox Camp . Three Three Five Two units units umits units A fourth 1000 K.W. generating unit with necessary switchboards and auxiliary machinery was installed in the CMR plant at Elmer. A submarine cable was then laid between this plant and site Fred so that the power load of that site could be partialiy carried by the Elmer plant. Due to the power demands at both Elmer and Fred during the operational phase, Figure 4-20. only part of the Fred load could be supplied by the Elmer plant; it was therefore necessary to operate the Fred plant throughout the operation to carry a share of the lead. Complete operating and production records of all fixed installations were maintained and reported monthly to the AEC. Power consump- tion for the entire operation is shown graphically in Fivure 4-21 for Eniwetok Atoll and in Figure 4-22 for Bikini Atoll. For reasuns of economy, electrical power distribution was generally made through overhead lines on sites Elmer and Fred. A’ submarine cable was required between these sites, however. and underground cables were used at ali other sites for scientific reasons. For the transfer of power over the submarine cable, the generated 2400 volts was first stepped up to 4160 volts and then stepped down to 2:00 Camp Po. er and Distillation Plant - Site Nan 1 eaeom ee cealiases er alt
