A bolt fixing device is configured so that a lock cap is pushed up by elastic force of an elastic member and engages upper surface teeth with lower surface teeth, the upper surface teeth being formed on the upper surface of a flange of a lock cap, the lower surface teeth being formed on the lower surface of an engagement flange of a body housing. Thus, the head bolt of a jet pump beam is fixed. With the configuration, when installing an inlet mixer, the head bolt of the jet pump beam is simply and reliably locked against rotation.

Jet pump and bolt fixing device of jet pump beam

A reactor metering pipe fixing device fixes a reactor metering pipe disposed in a reactor to a cylindrical outer surface of a jet pump diffuser and reduces stress that may be induced in a weld zone in the reactor metering pipe. An outer holding memberis held on the cylindrical outer surfaceof a jet pump diffuserby a C-shaped holding member. The reactor metering pipeis clamped from radial directions by the outer holding memberand inner holding membersand. Wedgesandare wedged into a gap between the cylindrical outer surfaceand the inner holding memberand a gap between the cylindrical outer surfaceand the inner holding memberto fix the reactor metering pipefirmly to the cylindrical outer surface
