1. A method of inspecting a reactor component in a nuclear reactor, comprising:lowering an inspection apparatus into a reactor pressure vessel of the nuclear reactor, the inspection apparatus including an installation platform and a scan head;securing the installation platform of the inspection apparatus to a first surface of the reactor component within the reactor pressure vessel; andmanipulating the scan head of the inspection apparatus to extend to wrap around the reactor component to an opposing second surface of the reactor component such that the installation platform remains stationary when the scan head is extended to wrap around the reactor component. 2. The method of claim 1, wherein the lowering includes disposing the inspection apparatus in an annular space, the annular space defined by the reactor pressure vessel and a core shroud. 3. The method of claim 1, wherein the lowering includes disposing the inspection apparatus between the reactor pressure vessel and the reactor component, the reactor component being a jet pump riser pipe. 4. The method of claim 3, wherein the jet pump riser pipe is secured to the reactor pressure vessel with a jet pump riser brace. 5. The method of claim 4, wherein the securing includes mounting the installation platform of the inspection apparatus between the reactor pressure vessel, the jet pump riser pipe, and jet pump riser brace. 6. The method of claim 4, wherein the manipulating includes maneuvering the scan head to access a junction between the jet pump riser pipe and the jet pump riser brace, the junction being in a form of a weld on the opposing second surface. 7. The method of claim 6, wherein the weld is at least one of a RS-8 weld and a RS-9 weld. 8. The method of claim 1, wherein the manipulating includes performing a first rotation of the scan head about a first axis and performing a second rotation of the scan head about a second axis such that a path of the scan head corresponds to a surface of the reactor component, the first axis being perpendicular to the second axis. 9. The method of claim 1, wherein the manipulating includes moving the scan head in a circumferential path to the opposing second surface of the reactor component. 10. The method of claim 1, wherein the manipulating includes performing an ultrasonic test on the opposing second surface of the reactor component. 11. The method of claim 1, wherein the manipulating includes encircling the reactor component with the scan head. 12. The method of claim 1, wherein the manipulating includes transitioning the scan head from a retracted state and an extended state, the scan head having a semi-circular shape in the retracted state and a circular shape in the extended state.
