1. Apparatus for inspecting a nuclear reactor comprising: a boom rotatably connected to a pivot point on a base;  means for controllably rotating the boom with respect to said pivot point on said base; and  a camera assembly affixed to said boom and being longitudinally slidable thereto such that the camera assembly may be slidably adjusted with respect to said boom.  a boom rotatably connected to a base at a pivot point, said base being affixed atop a nuclear reactor, said boom having a caster at one end such that said boom can rotate with respect to said pivot point and said caster;  means for selectively rotating and positioning said boom and said caster about said pivot point;  a camera slidably mated with said boom between first and second positions on said boom;  means for slidably moving said camera between said first and second positions along said boom;  means for rotating said camera means in a first direction with respect to said boom; and  means for rotating said camera means in a second direction with respect to said boom.  a boom rotatably fixed about a pivot point on said reactor head, said boom having a caster at one end such that said boom can rotate 360.degree. with respect to said pivot point and said caster;  means for rotating said boom about said caster;  camera and light means slidably mated with said boom such that said camera and light means can move between first and second positions on said boom; and  means for moving said camera and light means between said first and second positions on said boom.  (a) affixing a camera to a boom member;  (b) placing said boom member and camera on a rotational pivot point set on a position in said reactor and  (c) selectively rotating said boom member such that said camera and boom member can be selectively positioned within said reactor; and  (d) selectively rotating said camera and boom member can be selectively positioned within said reactor. 2. Apparatus of claim 1 further comprising means for adjusting said camera assembly in a vertical direction. 3. Apparatus of claim 1 further comprising means for adjusting said camera assembly in a horizontal direction. 4. Apparatus of claim 1 further comprising a light means lamp affixed to said camera assembly for illuminating said nuclear reactor. 5. Apparatus of claim 1 wherein said camera assembly is slidably adjustable by a drive screw situated longitudinally along the boom, which is in threaded connection with said camera assembly, such that when said drive screw is rotated in a first direction, the camera assembly slides in a first longitudinal direction along said boom, and when said screw is rotated in a second longitudinal direction, the camera assembly slides in the second direction with respect to said boom. 6. Apparatus of claim 1 further comprising a control module for controlling the rotation of the boom and the sliding of the camera assembly. 7. Apparatus for inspecting the reactor head of a nuclear reactor comprising: 8. Apparatus of claim 7 wherein said first direction is the horizontal direction. 9. Apparatus of claim 7 wherein said second direction is the vertical direction. 10. The apparatus of claim 7 further comprising light means connected to said camera for illuminating the area to be inspected by said camera. 11. Apparatus for inspecting the reactor head of a nuclear reactor comprising: 12. A method for inspecting a nuclear reactor comprising the following steps:
