Figure No. 2-50.
Fluor Tunnel Connecting Stations 1525 and
1526 — 65% Complete.
This station utilized a room space 25 feet
long by 15 feet wide, with a 934-foot ceiling
height with an extended area 17% feet long
by 12 feet wide. The long east side wall of the
station, except for the north 544-foot length,
was an existing retaining wall portion of Station
1524. The west side wall and the 5\4-foot-long
east wall were 12 inches thick over a continuous
‘spread footing. The roof slab was keyed and
dowelled into the existing retaining wall, 14
inches thick under a 5-foot barricade fill over
the larger room space and 12 inches thick over
the smaller extended room area. The east side
retaining wall surface contdifed the hydraulically
operated guillotine door assembly portion of
Station 1524. Access to the station was provided through the wood frame tunnel portion
of Station 1525. The station contained portable
lights, convenience outlets, power panel, field
phone, and portable power and field phone cable
to Station 1525 through the wood from the tunnel to the Fluorstructure.

Detector Station 1611 consisted of a re
inforced concrete structure, 21 feet long, 7%
feet wide by 7 feet high, divided into fourcells.
The work point of each cell was 100 feet from
the work point of Station 20 on radial lines.
The length of this structure was along the arc
of the radial lines of the four collimator pipelines of Station 1527, diverging from a radial
center at Station 20. Each cell contained a copper box. 144x1x1-5/12 feet high, lead and paraffin shielding, micarta detail, and precast wall
panels on the Station 20 side of the structure.
Extending away from Station 20 and beginning
at each cell of the concrete structure were four
48-inch-diameter corrugated metal pipes under
13 feet of fill, diverging in radial lines to terminate at the four Mirror Tower Stations 1523.01
through 1523.04. Shaft openings over the pipe
sections were filled with sandbags during the
test operation.
Beginning at the north wall of the Detector
Station and on converging alignment toward
the Station 20 work point were four T-shaped
steel plate duct sections 144% feet long, terminating at a concrete retaining wall and separated
from a second and nearly parallel retaining wall
by approximately three feet. The duct sections
