ABSTRACT:
A spacer pad for a nuclear control rod includes first and second halves each including a head and a shank. The shanks are configured for joining together the pad first and second halves, and the shanks are independently locked together for preventing the disassembly thereof. In an exemplary embodiment, the first and second shanks are threadingly joined together, and then independently locked together using a complementary hook and ledge respectively supported by the pad halves which allows assembly together of the pad halves but prevents disassembly thereof.
