These Stations were for Rad Chem analysis, Project 11.1. ENGINEERING. Thecriteria were received on 1 October. Two drawings were started on 27 October. The drawing for Station 1110 was submitted by 3 November and approved on 21 December. The drawing for the other Stations was submitted on 27 October and approved on 17 November. CONSTRUCTION. Work was scheduled to commence on 1 November and to be comp!cted by 31 December. Actual construction starting dates varied from 6 to 20 January. All Stations were completed on 30 January 1954. STATION 1120.01 PORTABLE COLLECTOR - SITE ZEBRA USER: LASL ¢ corridor and utility room that housed the electrical and mechanical equipment. Access to the utility room was provided through a 4’ - 2” wide x 9’ 0” high tunnel. At about 18 feet from the end of the utility room. the tunnel turned 90 and extended for about 40 feet on a slight upward grade to a covered entrance. The tunnel entrance had two openings, each enclosed by a steel, blast-resistant door. A 5’-0” x 7’-0" protected area outside the opening was completely housed hy a smail reinforced concrete box-like structure called the vestibule. The main entrance opened onto a reinforced 16’-0” x 20-0” concrete ioading platform and a 20’-0” x 68’-0” loading ramp. This Station was used for Reaction History, Project 12.1. STATION 1200 - RECORDING STATION SITE CHARLIE - USER: UCRL MECHANICAL. Dehumidification was provided in the three instrument rooms. The corridor utility room was ventilated with filtered fresh air. The rooms were kept under a dry air pressure preventing infiltration of large quantities of humid corridor air whenever the doors to these rooms were opened. Conditioning units in each room recirculated, cooled and reheated the room air as required to maintain desired conditions. GENERAL. This was a heavy reinforced, earth covered rectangular structure, 41'-0” x 49’-0” with a tunnel entrance. It was divided into three rooms and opened at one end into a ELECTRICAL. The power to the Station was received from the gencrators at Station CH-500 through three 75 KVA transformers’ in Substation CH-1200-X. One feeder served the light- GENERAL. An area with a 25-foot radius was staked out and cleared in the center of which a geographic position was determined. This Station was for a sample cullection, Project 11.2. ue! woot Page 2-107 . : oe. 1 i 3 boynem ulebes wii atas re ocd }\
