Abstract
In the present study, an independent RELAP5-RT input deck for the LungMen Nuclear Power Station of Taiwan Power Company is developed. LungMen nuclear power station employs the Advanced Boiling Water Reactor (ABWR) designed by General Electric. RELAP5-RT is a thermohydraulic system analysis program developed by INEL. The work involved in the study includes: 1. combine the RELAP5-RT thermal hydraulic input decks of reactor vessel and balance of plant into an integrated deck. These input decks are parts of the Advanced Lungmen Plant Simulator (ALPS) developed by the Nuclear Power Plant Dynamic Simulation and Analysis Lab of National Tsing Hua University. 2. Implement the control logic of feedwater control system (FWCS), and steam bypass and pressure control system (SBPC) into the merged deck. These control logics are adopted from ALPS. Together with the control logics of recirculation flow control system (RFCS), reactor protection system (RPS), rod control and information system (RCIS), which have been developed in previous work, a transient analyses tool of LungMen NPS has been completed. The deck developed is used to simulate two power test transients of the plant-“one feedwater pump trip” and “Load Rejection” . The results are compared with the results of the GE’s STAR and the ALPS’s simulation. The comparisons show that the RELAP5-RT input deck of Lungmen Nuclear Power Station developed in the present study functions properly.
