A blower, blower mount platform, diffuser modules, aeration manifold, aeration chamber, an adjustable, telescoping aeration chamber extension, baffles, and buoyancy apparatuses attach to a frame. The diffusers are located beneath the surface of the body of liquid at a predetermined, fixed depth. The blower supplies air to the diffusers and liquid-bubble mixture is released into an aeration chamber where artificial aeration is maximized. The mixture then rises through the aeration chamber. Bubble dissipation and flow conditioning baffles force bubbles to coalesce and vertically dissipate into the atmosphere. The liquid flows over the top of the baffles and a flow manipulation rim to radiate outward and parallel to the pond surface with minimum turbulence at an optimum flow discharge rate. The aerator provides optimized oxygen transfer at low energy costs.

In an underwater remote surface inspection method for a reactor constituting member, in order to improve the precision of an operation of inspecting a surface shape of the reactor constituting member, an underwater remote surface inspection apparatus includes a replica picking head, an ultrasonic vibrator, and a replica agent cartridge. The replica picking head is pressed against a surface of core internal structure as an inspection target.
