Abstract
Characteristics of heat release process, while the Wigner energy was drawn off the graphite during DSC(Differential Scanning Calorimenter) measurement as an example of annealing process which is one of release methods of Wigner energy that is contained in the irradiated graphite, was studied. Linear temperature rise method in DSC operation was selected to estimate the total Wigner energy content and the heat release rate of each graphite samples, which were located in several positions in the thermal column in KRR-2 research reactor. As an annealing process in DSC operation Wigner energy of the irradiated graphite samples were totally released by heat supplying to the graphite from room temperature to
중성자가 조사된 흑연에 내재되어 있는 Wigner 에너지를 배출시키는 방법의 하나인 가열냉각공정의 적용 예로 DSC(미분 주사선 열량계) 측정을 통해 흑연으로부터 Wigner 에너지가 배출되는 열 배출 특성을 연구하였다. 일정온도 상승 방법 에 의한 DSC 운전에서 중성자가 조사된 흑연을 가열냉각(annealing)하는 동안 배출되는 Wigner 에너지의 총량과 처리온도에 따른 배출속도를 측정하였다. 연구로 2호기(KRR-2) thermal column 내에 위치별로 중성자의 조사량에 차이가 나는 흑연 시료를 분말로 만들어 상온에서
