One last thing-- Section VIII UW-15(d) requires that reinforcing pads have a telltale hole to check the soundness of the welds joining the nozzle to the vessel wall. No mention of gas or air or water trapped in the space. The hole can be plugged in service but not with anything that can sustain pressure between the plate and the wall of the vessel. Even a pinhole leak in a nozzle weld could pop off a reinforcing pad.
