Note (General)
出版タイプ: NA
Radiation Shielding design/safety analysis required for licensing of the high intensity proton accelerator facility J-PARC (Japan Proton Accelerator Research Complex) is in progress, using various high-energy particle transport codes. Shielding benchmark problems, mainly based on experiments, on thick target neutron yield, beam dump geometry, deep penetration and radiation streaming were prepared and analyzed by the shielding design codes, in order to estimate the code's accuracy. The results of analyses show that the calculation results agree with the experiments within a factor of two on the whole.
大強度陽子加速器施設J-PARC(Japan Proton Accelerator Research Complex)の放射線遮蔽設計及び許認可申請における安全解析においては、数種類の高エネルギー粒子輸送計算コードが用いられている。そこで、これらの計算コードについて精度評価を行うため、おもに実験に基づいた、厚いターゲットからの中性子生成量,ビームダンプ体系,遮蔽体深層透過及びストリーミングといった遮蔽ベンチマーク問題を作成し、解析を行った。その結果、各計算コードによる結果が、全体としてファクター2以内の精度で実験値を再現することを示した。
