Apparatus and method for refurbishing a spectral shift mechanism for a nuclear reactor fuel assembly
In combination with a nuclear reactor spectral shift mechanism having at least one elongated hollow water displacer rod being substantially field with a moderator/coolant liquid, a refurbishing apparatus is described comprising: (a) first means disposed in flow communication with an upper portion of the interior of the hollow rod; (b) second means disposed in flow communication with a lower portion of the interior of the hollow rod; and (c) means interconnectable with the first means and second means so as to provide an entrance path for air under pressure to the upper portion to the hollow rod via the first means and an exit path for water from the lower portion of the hollow rod via the second means. The interconnectable means includes: (i) a generally cylindrical member having an opening defined at one end thereof, a pair of first and second ports displaced from one another and a central plenum communicating with the end opening and the ports, and; (ii) a generally cylindrical charging tool having defined therein a pair of first and second flow passageways with corresponding first and second flow opening.
