AbstractThe given work concludes a series of total neutron leakage multiplication experiments performed in the RRC ‘Kurchatov Institute’ with several perspective neutron multiplying materials, such as U, Th, Bi, PB and Be. It is devoted to the measurements and calculations for seven beryllium spheres combined from the spherical shells belonging to the USA, PRC and RF. The total leakage multiplication measurements were carried out using the total absorption detector (TAD) method with the use of a boron tank. The calculations were carried out by the MCNP/4A transport code with FENDL-1 and JENDL-FF data. A comparison of experimental and calculated results has shown good agreement (within the experimental uncertainty ∼ 3–4%) of the leakage multiplication values for all the spheres covering the range of beryllium layer thickness from 3 to 20 cm.

本稿は、RRC「クルチャトフ研究所」において、U、Th、Bi、Pb、Beなどのいくつかの有望な中性子増倍材料を用いて実施された一連の全漏洩中性子増倍実験をまとめたものである。本稿は、米国、中国、ロシアの球殻を組み合わせた7つのベリリウム球についての測定と計算に焦点を当てている。全漏洩中性子増倍の測定は、ホウ素タンクを用いた全吸収検出器(TAD)法により実施された。計算は、FENDL-1およびJENDLデータを用いたMCNP/4A輸送コードにより実施された。実験結果と計算結果の比較により、ベリリウム層の厚さが3cmから20cmの範囲のすべての球について、漏洩中性子増倍率の値は実験誤差(約3〜4%)の範囲内で良好な一致を示した。
