Abstract
Mitigation of fast neutron irradiation damage on reactor vessel and improvement of mechanical integrity are desired for the successful plant life-time extension. In this study, the performance of metallic hydride for this application is reviewed and compared. First, selected prospective metallic hydrides are evaluated by MCNP code and put into the attenuation test using Cf-252 neutron source. Since for the reactor application high moderation and reflection with no absorption are favored, Z factor is introduced for the evaluation. According to the Z value estimation
자체 개발한 수소화금속을 이용하여 고속 중성자 방사선을 효율적으로 차폐할 수 있다면 방사선 안전신기술 개발과 확립에 큰 기여를 할 것으로 생각되어 본 연구를 시행하였다. 여러 수소화 안정 금속들을 대상으로 핵적 특성, 단위 부피당 수소원자함유 수 등의 예비평가를 통하여 수소화금속(
