内容記述 |
Significant quantities of neutrons and gamma rays deduce the nuclear heating on the shielding walls of the test cell (TC) in the A-FNS. This study presents nuclear and thermal analyses of the shielding wall in the A-FNS to evaluate its radiation-shielding effectiveness and cooling capacity. Previous designs incorporated cooling water pipes embedded in the concrete shielding wall for thermal management. However, we determined that this approach failed to maintain concrete temperatures within specified limits due to the low thermal conductivity of concrete and the challenge of ensuring adequate contact between the concrete and piping. We developed a new shielding wall design that eliminates the need for cooling pipes inside the concrete. This updated design integrates an 85 cm of stainless steel 316 L (SS316L) structure containing 20 % cooling water positioned in front of the concrete, which maintains concrete temperatures within acceptable limits. In addition, nuclear assessments of this revised shielding wall structure were conducted to verify its radiation shielding capacity. Results indicate that the effective dose criteria are met at thicknesses of 255 cm for heavy concrete and 335 cm for ordinary concrete when the 85 cm of combing structure of SS316L/water (20 % water) is included. |
