Stress Analysis of Pressure Vessels in Nuclear Power Plants (Part II : Stress Analysis of Tapered Cylinder in the Shell-Head Junction)
원자로압력용기의 응력해석 (제 2 보, 원데이퍼진 원통부의 응력해석)
Abstract
Stress analysis of tapered cylinder of reactor vessels is investigated by means of the intersection method. The tapered cylinder is approximated into three models-average cylinder, conical frustum, and ring. The results are compared with those of the finite element method program and an experiment. In this paper, the following results are obtained: (1) the best aproximation has been obtained by the ring model analysis: (2) the intersection analysis of the tapered cylinder by the ring model shows a sufficient accuracy for the stress analysis of reactor vessels.
