Abstract

Abstract

In applying the design of secondary-side passive residual heat removal system (PRS) of Generation 3 PWR to Generation 2⁺PWR, there are limitations due to the long distance between the cooling water tank of the PRS with the shell of the PWR, which complicates the arrangement of the relatively long steam pipe and condensation pipe of the PRS. This paper presents an improved design for PRS. The ARSAC code was used to simulate and calculate the transient process of the system under different operating conditions, namely, the initial isolation valve of the steam pipeline was closed and the pipeline was filled with nitrogen, steam, and water, respectively. The results were compared with those obtained under the initial condition of an open valve. The comparison results show that all designs can meet the requirement of residual heat removal, but have advantages and disadvantages in engineering feasibility and system operational stability. Therefore, the improvement design with the steam pipe are full of nitrogen is most recommended to apply in engineering.
