barge on which were installed a salt water shower system with necessary pump and fuel systems and two 8-mantents; one for a dressing room and stowage of clothing and the other for an office and radio-phone station, In order to provide for continuous operations in the dock area at Eninman after contamination (as a result of the BRAVO event), the area was cleared of several inches of surface, All equipment required for operations at Bikini which had become contaminated to an extent precluding operation without overexposure was decontaminated by washing down until the level was reduced sufficiently to permit safe operation. Airukiiji - Airukiraru islands airstrip, which was non-operational for eight days due to wave-deposited debris from the BRAVO shot, was made operational when radiation levels permitted TG 7.5 working parties to reenter the area. The wave from UNION also put the airstrip out of commission but it was placed in operational condition within three days after the shot, Rolling stock, equipment and personaleffects were shipped from the Bikini area to Eniwetok for decontamination. The existing Rad-Safe facilities at Parry Island, however, were taxed beyond capacity, especially in regard to heavy equipment. It was therefore necessary to build an additional fenced-in wash-down area on Parry, which was approximately 150 ft. x 200 ft. contain- ing a 50 ft. x 50 ft. concrete slab for water run off. Fresh and salt water lines were laid, and a boiler was installed to supply the necessary live steam to clean off engine and chassis grease. Salt water was used for washing down the contaminated equipment. TG 7.5 personnel decontaminated the equipment without delay to allow the various Task Groups to make preparations for an ‘Wy early return of their equipment to the Z.I, CHAPTER 3.1 3. CONSTRUCTION EQUIPMENT COMMENTS In June 1952 the Field Manager requested the Contractor to prepare a report on probable facilities required on Bikini Atoll. This request resulted in a careful study of construction equipment and other long delivery items for the purpose of evaluating the capability of carrying on construction work at two widely separated sites, Since reinforced concrete construction is one of the major items in any operation, the requirements for large scale coral aggregate production equipment were finalized. Two rock crushing and screen- ing plants were ordered and were delivered in March 1953. By April 1953, the scientific construction scope was well defined for both atolls. Islands and locations were selected for material stockpiles, crushing plants were placed in operation and concrete batching plants were set up. Coral aggre- gate quarries were located at four locations on Bikini Atoll and at three lo- cations on Eniwetok Atoll. Two crushing plants were assigned to Bikini and one plant to Eniwetok; all three plants were in production inApril 1953. Hav- ing this equipment available for an early start on this work was one of the major factors in meeting scheduled construction completion dates. 3 Copled/DOE LANL, J-Div. 65 CS
