This paper presents an overview of the VISA (Visual System Analyzer) and RELAP5 (Reactor Excursion and Leak Analysis Program, version 5) softwares Preliminary results of modellings, simulations and calculations of the thermal hydraulic system of a practical VVERtype PWR nuclear power plant (NPP) using these softwares are presented as well This research has important practical implications, especially for the nuclear power plant that will be built in Ninh Thuan, Vietnam The reactors adopted in the Ninh Thuan NPP would be the Russian VVER PWR At this point, our research is a basic important step towards a practical study case TCr khoa: VISA, RELAP5, Nuclear Reactor, PWR, Nulcear Power Plant (NPP), Thermal hydraulic VVER-1000 Ninh Thugn NPP I MO DAU Cac chuong trinh tinh toan mo phong thuy nhiet uoc lucmg tot nhat (vi du Relap5) da dugc phat trien tir kha lau va cang dugc hoan thien nham mo hinh hoa he thong thuy nhiet 16 phan ung va nha may dier hat nhan, cGng nhu tinh toan va mo phong cac hien tugng thuy nhiet quan trong nha may dien hat nhan Viec ung dung, sir dung cac chuong trinh CO xu huong gioi ban cac nhom chuyen gia Su phat trien nhanh cua may tinh cho phep cac chuong trinh tinh toan co the chay tot tren may tinh ca nhan tao diSu kien cho viec cap chiing rgng rai Tuy vay mgt ban che Ion \h\ t6n tai la viec chuan bi file so lieu dau vao cho chung thucmg phuc tap va d l co sai sot Chuong trinh VISA da dugc KAERI va KHNP Han Quoc hgp tac phat trien de thuc hien nhiem vu la mgt giao dien hga tien dung giiip nguoi su dung co the khai thac hieu qua ban cac chuong trinh tinh toan mo phong thuy nhiet [1] VISA co the tich hgp dugc voi chuong trinh: MARS, RETRAN3D va RELAP5 O day chung toi chi nghien cuu, tim hieu kha nang lam viec va h6 trg cua VISA cho RELAP5 (VISA_RELAP5) Cac dac tinh co ban cua VISA bao g6m [2]: - dam bao tinh nguyen ven ciia dir Heu d^u vao cua RELAP;
