An apparatus for testing a nuclear fuel assembly for leaks by sweeping a fluid along the fuel assembly while the fuel assembly is disposed in a pool. The apparatus includes a bridge overlying the pool and a mast assembly depending from the bridge. The mast assembly includes an outer, stationary mast and an inner, movable mast adapted to hold the fuel assembly and to position the fuel assembly in the interior channel between the upper and lower ends. The apparatus includes an injection assembly including an injection conduit, a nozzle and a clamp system for securing the nozzle to the outer mast. The apparatus also includes a suction conduit having an inlet disposed in fluid communication with the interior channel for collecting the fluid after the fluid sweeps the fuel assembly.
