Abstract
An assembly adapted to access a weld extending circumferentially around a core shroud of a nuclear reactor, wherein the core shroud is contained in a pressure vessel reactor, the assembly including: a baffle plate rail having a lower surface adapted to abut a baffle plate in a gap between the core shroud and the pressure vessel reactor; a telescoping rail slidably coupled to an upper region of the baffle plate rail, and a reciprocating rail slidably coupled to an upper region of the telescoping rail, wherein the reciprocating rail includes at least one of a weld conditioning tool, a weld inspection sensor and a weld repair device.
