초록

방사선 조사선량이 사용후 핵연료 수송용기 등에 사용되는 에폭시수지계 중성자 차폐재들의 인장강도, 압축강도, 굴곡강도, 비중, 무게 변화 및 수소함량 변화 등 역학적 성질에 미치는 영향을 검토하였다. 0.5MGy까지는 방사선 조사선량의 증가에 따라 KNS-ll5A, KNS-ll5B 및 KNS-ll5C(Kaeri Neutron Shield) 차폐재들의 인장강도, 압축강도 및 굴곡강도는 증가하는 경향을 나타냈으나, 0.5MGy 이상에서는 감소하는 경향을 나타내었다. 또한 조사선량의 증가에 따른 차폐재의 비중 및 무게는 크게 변하지 않는 것으로 나타났으나, 수소함량은 감소하는 경향을 나타내었다.

Effects of radiation dose on mechanical properties such as tensile strength, compressive strength, flexural strength, specific gravity and changes of weight and hydrogen content of epoxy resin-type neutron shielding materials to be used for spent fuel shipping casks have been investigated. At radiation dose up to 0.5MGy, the tensile strength, compressive strength and flexural strength of the shielding materials of KNS-115A, KNS-115B and KNS-115C have been increased with increase in the radiation dose. In contract, these mechanical properties have been decreased at radiation dose above 0.5MGy. The amount of radiation dose on the materials of KNS-115A, KNS-115B and KNS-115C has not resulted in a measurable loss of specific gravity and weight of them, whereas the reduction of hydrogen content has been observed.
