A core spray sparger T-box attachment assembly for a nuclear reactor pressure vessel may include a downcomer pipe coupling and a sparger T-box clamp (1000). The pressure vessel may include a shroud, the sparger T-box penetrating the shroud, a plurality of sparger distribution header pipes (302, 304) coupled to the sparger T-box, and a downcomer pipe (108). The sparger distribution header pipes (302, 304) may include at least one sparger nozzle. The sparger T-box clamp (1000) may include an anchor plate (1004) having a draw bolt opening (1022) to receive a draw bolt (1002), a first clamp block (1006) substantially aligned at a first end (1010) of the anchor plate (1004), and a second clamp block (1008) substantially aligned at a second end (1012) of the anchor plate (1004). The anchor plate (1004) may be connected to the first clamp block (1006) by a first multiple-degree-of-freedom connection (1014). The anchor plate (1004) may be connected to the second clamp block (1008) by a second multiple-degree-of-freedom connection (1016). |
