    摘要： A breaker valve assembly (10) for a nuclear reactor containment includes a valve body (12), a valve body insert (14), and a lid (36). The valve body includes a first side wall (28) defining a chamber, a first opening (52) in a top portion of the first side wall, and a second opening (50) in a bottom portion of the first side wall. The second opening communicates with the first opening of the valve body. The valve insert body includes a second side wall (30) defining a second chamber, and a third opening (62) in a bottom portion of the second side wall. The valve insert body is nested in the valve body. The lid is arranged on an upper edge of the side wall of the valve insert body. The valve insert body is configured to move substantially vertically with respect to the valve body.
