(A) numerical model for analysis of direct containment heating by dispersed debris
학위논문(석사) - 한국과학기술원 : 원자력공학과, 1992.2, [ viii, 44 p. ] A simple numerical model has been developed to analyze the effects of releasing molten debris into the Containment Vessel (CV) which is filled with air in certain severe reactor accident scenarios. This model predicts the time dependent heat up of...
