<p>A high-pressure safe injection system for nuclear power stations is configured on multiple loops (5) of a loop system of a reactor. The high-pressure safe injection system comprises at least one boric acid injection unit (15) and at least one coolant injection unit (16). The boric acid injection unit (15) comprises a concentrated boric acid injection box (8) and a concentrated boric acid injection pipeline (7). One end of the concentrated boric acid injection pipeline (7) is connected to the concentrated boric acid injection box (8), and the other end of the concentrated boric acid injection pipeline (7) penetrates into a containment vessel (11) and then is connected to a cold tube section (501) of a loop (5) of a loop system of the reactor. The coolant injection unit (16) comprises a water source (14) and a coolant injection pipeline (6) connected to the water source (14). The coolant injection pipeline (6) comprises a cold tube section injection pipeline (9) and a heat tube section injection pipeline (10) that are connected in parallel; the cold tube section injection pipeline (9) penetrates into the containment vessel (11) and then is connected to a cold tube section (501) of a loop (5) of a loop system of the reactor; and the heat tube section injection pipeline (10) penetrates into the containment vessel (11) and then is connected to a heat tube section (502) of a loop (5) of a loop system of the reactor. Multiple pipelines of the injection system are not mutually interfered, thereby facilitating flow control; and the injection system has high security.</p> |
