STATION DESIGNS The following is a complete list of scientific stations by number, location, User, descriptive identification, and brief design history. (A list of Users may be found in Chapter 1.2, Volume 1 of this report. ) Station 1 - Engebi, Eberiru, Runit, and E#% These stations were zero towers, discussed in Chapter 5.11 of this Volume, Station 2 - Engebi, The Aomon Group, Runit, and E*- NRL, The re- quirements of this building necessitated only a 9 foot by 3 foot by 7 foot wooden building strong enough to withstand normal loadings plus 2 feet of earth cover; it did not have to withstand blast conditions. The floor was placed 3 feet, 6 inches below natural grade, so that only half the hut extended abeve grade, J-Division for the AEC furnished H&N the floor plan, building description, and location on March 31, 1950. Further information was given on May 12, 1950, The locations of the buildings at the various sites were revised on May 24, 1950, and again on November 10, 1950, by J-Division, Stations 3, 4, and 5 - Engebi, Runit, The Aomon Group, and E+- NRL. Stations 3, 4 and 5 were power outlets on posts, The original sketch was furnished April 24, 1950, All Stations 3 and 4 were relocated on November 10, 1950 by J-Division, At the same time Station 5 was added to the program, Station 5 at Engebi was deleted by AEC on December 19, 1950. Station 3 on Engebi was relocated and Station 5 on Runit added by AEC on February 6, 1951. Station 6a — Engebi, The Agaon Group, and Runit — NRL, These concrete buildings were built for the Sandstone Operation, amd the revamping consisted of plugging the conduits in the front wall and drilling 34 new holes in the side and rear walls. These holes varied in size from 2 inch to 8 inch diameter, Because of the desire for uniformity of dehumidification equipment, the existing units were removed and new ones installed. _ Run: A Because of the increased. scope of WRLTs projects, an additional timing station was required of the same interior size as Station 6a - 23 feet by 13 feet, by 7+ feet, The preliminary sketches furnished in October 1949 contained sufficient information so that only minor revisions, such ss changing an electrical panel at the Jobsite on February 12, 1951, were necessary. The walls and roof of the building were 14 inches thick, The structure was streamlined by placing earth fill up to the top of the roof slab, The earth was kept away from the access doors in the rear by concrete wing walls. Station 6c - Engebi, The Aomon Group, and Runit - NRL, This station was a 16 foot by 32 foot tent placed adjacent to the Station 6a and 6b structures for use as a work shop, The description and locations were furnished by the AEC on October 10, 1950. 9-157
