CHAPTER II, SECTION 3 STATIONS: PURPOSE: SITE: USER: PARTICIPATION: CONSTRUCTION: 3012.01 and 3012.02 Fireball Study Sally DOD-30 1 and 2 4-12-56/5-13-56 These stations were two User-furnished 75-mm recoilless rifles mounted on the roofs of Stations 1 and 2 and aimed to fire down at Stations 3013.01 thru 3013.03 which were located on the sides of the towers at the 175’ and 275’ levels. Power consisted of 1 KW, 110- of earth with a 2:1 side slope. An area for batteries was provided. Unistruts located in the ceiling and walls secured the User equipment. A 16’x 16’ tent was located nearby for project use. Power was supplied from the main island powerhouse to a substation outside of Station 3020 through a 100-amp, 3-phase oil fuse cutout. Minus 45 minutes, 15 minutes, 1 minute, minus 15 seconds, and zero test signals were required. A total of 365 cubic yards of concrete was used which had an average 28-day cylinder break of 3,735 psi. volt, single-phase. Timing signals of minus 15 minutes, minus 5 minutes, and minus % second plus 1 millisecond were required. STATIONS: PURPOSE: 3013.01 thru 3013.03 75-MM Projectile Catchers SITE: Sally USER: DOD-30 PARTICIPATION: 1 and 2 CONSTRUCTION: 5-20-56/5-22-56 These stations were projectile catchers weighing approximately 2400 pounds each. Station 3013.01 was mounted on structural steel brackets at the 175-foot level of Station 2, Wr te Station 3013.02 was at the 275-foot level, and Station 3013.03 at the 175-foot level of Station 1. No power or timing signals were required. STATIONS: PURPOSE: SITE: USER: PARTICIPATION: CONSTRUCTION: 3014.01 and 3014.02 Projectile Catcher Basins Sally UCRL 1 and 2 4-2-56/5-23-56 These stations were concrete basins filled with water to catch the 75-mm projectiles fired from towers 1 and 2. Station 3014.01 was 10’ x 30’ x 6’ deep and Station 3014.02 was 10’ x 47’ x6’ to 9 deep. The stations were located at the foot of each tower. No power or timing signals were required. A total of 79 cubic yards of concrete was poured. STATION: PURPOSE: SITE: USER: PARTICIPATION: CONSTRUCTION: 3020 Recording Shelter Yvonne 30.2 (Sandia Corp.) 24 1-3-56/4-28-56 Station 3020 was a reinforced concrete structure with inside dimensions of 10’ x 28’x 7’-6” high, and with 4’-thick walls and tapered wing walls on each side of the entrance. The station was covered with approximately 3 feet Page 2-120 Figure 2-113. Station 3020 - 85% Complete STATIONS: PURPOSE: SITE: USER: PARTICIPATION: CONSTRUCTION: 3021, 3022, 3023 and 3024 Vulnerability Test Yvonne 30.2 (Sandia Corp.) 24 2-10-56/4-19-56 These stations each consisted of two standard 5-inch pipes approximately 10 feet long embedded in 4’ x 4’x 4’-4” deep concrete footings and guyed with two %-inch steel rods which were embedded in 4’x 4’x 3’ concrete anchor blocks. The rods were designed to give way upon the arrival of the shock wave. Between each pair of pipe towers, the User suspended a large device on cable which was designed to slip off of the pipe column tops when the shock wave arrived. Pipe gage mount towers with User-furnished gages were used in connection with these stations. Stations 3022, 3023 and 3024 had minus 45 minutes, 15 minutes, 1 minute, and minus 15 seconds timing signals. No signals were provided at Station 3021, and no power was required for any of these stations. Eighteen yards of concrete were used in Station 3021 and a total of 86 cubic yards was used in Stations 3022 thru 3024.
