200 ft are relatively free from a background of ground-scattered neutrons. In each experiment the neutron flux reaching a BF, detector placed inside the detector tank and near a side wall was measured as the altitudes of the source and the detector were varied simul- taneously from the ground to 200 ft. The only major difference between the two experiments was the shielding placed around the TSF reactor. In the first case the reactor was placed in the reactor tank at a distance (p) of 45 cm from the tank wall and a reactor angle (e) of 330 deg from the source- detector axis;14 in the sec:ond case the reactor was placed in a mockup of the GE-ANP 8-1 shield design (see “TSF Experiment with the Mockup of the GE-ANP R-1 Shield Design,” in Sec. 15). In order to estimate the actual ground-scattered contribution at the 200-ft altitude, attempts were made to analytically separate the experimental measurements into their air- and ground-scattered components. A calculation16 of the number of neutrons singly scattered into a point isotropic detector as a function of the solid angle in which they had left the source had been made previously PERIOD ENDING DECEMBER 70, 7954 Fig. 12.9.

Also, a calc~lation~~ Emitted from GE-ANP R-1 Shield Mockup. of the number of air-scattered neutrons lost because of the presence of the ground and the number of ground-scattered neutrons reaching the detector as a function of source solid angle and altitude had been made, All three calculations assumed single isotropic scattering, air attenuation, and a separation distance of 64 ft.I8 The integration over the source solid angle to obtain curves of air and ground scattering as a function of altitude was weighted in each case by the anaular d -of neutrons emitted from ata, it was assum e ground- 18The measurements with the GE-ANP R-1 mockup were actually for a 70.8-ft separation distance. c .- 2 c 3 4 ? 3 ._ e - X 3 _J LI z z 8 t- 3 z Li 2 W > I 5 _J w n e€m?!r 2-01-056-3-T 20 0 0 20 60 80 100 120 140 1’50 180 8, ANGLE WITH RESPECT TO REACTOR-CREW SHIELD AXIS (degl scattered contribution to the data at 200 ft was negligible, and the single air-scattering curve as a function of altitude was normalized at this point. This normalized curve was then used to subtract the air-scattered contribution from the experimental measurements at lower altitudes, and thus (1 series of experimental ground-scattering points was obtained. A fit of the calculated ground-scattering curve through these points gave an estimate of the ground-scattered contribution to the experimental data at the high altitude. The air-scattering was then renormal ized, with this ground-scattered contribution taken into account. This method of iteration, of course, quickly converges. The analysis (Fig, 12.10) for the differential typeof experiment resulted in an estimate of 1% for _. the ground-scattered co water-filled reactor tank. The estimate obtained 19H. E.
