KẾT LUẬN
Luận văn đã mô phỏng thành cơng bình điều áp lị AP1000 bằng chƣơng trình tính tốn thủy nhiệt RELAP5 tại trạng thái dừng và trạng thái chuyển tiếp khi xảy ra sự cố vô ý mở van an toàn.
Luận văn đã thực hiện đƣợc các tính tốn liên quan đến áp suất, nhiệt độ của bình điều áp trong trạng thái dừng và chuyển tiếp.
Kết quả tính tốn cho thấy, dữ liệu đầu vào của bình điều áp là phù hợp với kết quả của những nghiên cứu trƣớc đó, có thể sử dụng làm cơ sở để hoàn thiện xây dựng dữ liệu đầu vào cho tồn bộ lị AP1000 và thực hiện các phân tích an tồn khác.
Kiến nghị: Tiếp tục nghiên cứu để hồn thiện mơ phỏng tồn bộ lị AP1000, để có thể hỗ trợ cơng tác thẩm định an tồn nếu cơng nghệ AP1000 đƣợc chính thức đề xuất cho dự án điện hạt nhân Ninh Thuận 2.
