Research and Development of One Dimensional Two-phase System Code Used in PT-SCWR

Abstract

The main content of this paper is to build up a program to simulate the PT-SCWR moderator system. The system is a passive two phase natural circulation loop and can be parted into two parts: loop and heat exchanger. Along the whole loop, we chose the two-fluid model to describe the physical phenomenon, while some particular equations are added for different characteristic.Finally, we simulate the test loop to gain the computational result. The results show that the system is able to remove the redundant heat of moderator and can help to design the parameters of the test facility.
