초록

고화 입자 크기의 관점에서 TROI 용융물-냉각수 반응 실험의 결과에 대한 물질 효과를 분석하였다. 고화 입자 크기를 분석하면 용융물-냉각수 반응에서 초기 조건, 혼합, 폭발을 기적으로 해석할 수 있다. 증기 폭발이 발생한 경우와 폭발이 발생하지 않는 경우의 고화 입자 크기를 분석한 결과 증기 폭발이 발생한 경우에는 미세 입자가 많고 비교적 큰 입자는 적은 것으로 나타났다. 또한, 혼합 과정에 대한 정보를 보존할 수 있는 증기 폭발이 발생하지 않은 용융물-냉각수 반응을 이용하여 용융물 입자 크기에 대한 물질 효과를 분석하였다. 증기 폭발이 잘 발생하는 용융물은 증기 폭발에 참여할 수 있는 큰 입자를 많이 포함하고 있었고, 증기 폭발이 잘 발생하지 않는 용융물은 증기 폭발보다는 냉각되기 쉬운 작은 입자 혹은 미세 입자를 많이 포함하고 있었다.

The effect of materials on fuel coolant interactions (FCIs) was analyzed on the basis of a solidified particle size response for TROI experiments.$^{(1)}$ The solidified particle size response can provide an understanding of the relationship among the initial condition, the mixing, and an explosion. Through a comparison of the size distributions of the solidified particles in the case of explosive and non-explosive FCIs, it is revealed that an explosive FCI results in the production of a large amount of fine particles and a small amount of large particles. The material effect of the size of solidified particles was analyzed using non-explosive FCIs without losing the information on the mixing. This analysis indicates that an explosive melt includes large particles that participate in the steam explosion, whereas a nonexplosive melt includes smaller particles and finer particles.
