Experimental Confirmation of the Concept of Two-Section Cascade-Type Blankets

Experiments on cascade-reactor models

“…Information on the arrangement and the results of the first experiments has already been presented in [17]. In the present paper, similar information is presented on the later experiments Nos.…”

“…Since the physical processes determining the ratio of the intensities and the cascade gain are related, the experimental coefficient can be determined from the simple proportionality rule A exp = (1.715/1.470)A comp (Table 4). The cascade gain per source neutron can be compared with the analogous data in the first experiment performed with 252 Cf as the neutron source (see Table 1 [17]). Essentially, in the second experiment appreciably higher experimental and computed values were obtained for the same models: in the first experiment 1.71 and 1.82, respectively, and in the second experiment 2.71 and 2.32.…”

“…The experimental values of P 1 in the neptunium section were obtained using Eq. (2) of [17], and P 2 and P 0 in the salt section were obtained by directly summing the number of fissions in all uranium pellets. The results of the measurements and the calculations of the neutron characteristics of the laboratory models are presented in Table 5.…”
