This paper presents the thermal behavior of concrete structure due to hydration heat. To determine thermal properties in concrete induced from hydration heat, temperature variation, strain and thermal stress were measured by using the embedded type concrete gauges in the tendon gallery wall of the containment building. The test results showed that concrete temperature, strain and thermal stress were strongly affected by the location of measuring points and surrounding environmental conditions of members. A finite element analysis was also performed to clarify the thermal behavior of concrete. The analytical results correlated very well with the tendency of measuring value. Slight differences in stress value and generation timing were noticed due to the differences in restraint condition of the basemat against the walls and creep characteristics of high temperature concrete.
