This study was to analysis the hydration heat and crack index considering the buttress part of the basic nuclear containment walls. The maximum hydration heat of buttress part was higher about 6% than those conventional containment wall. Also, early crack index of buttress part by hydration heat was decreased about 26% than conventional containment wall. Whereas the crack index by external restraint were similar on the all of specimens.
