Abstract
Abstract The irradiation specimen installation apparatus comprises a gripper mechanism capable of being disposed through a hole in the nuclear reactor core barrel flange and capable of gripping the irradiation specimen. The apparatus is also capable of transporting the irradiation specimen so that the irradiation specimen can be deposited in the specimen container. The apparatus also comprises a visual verification mechanism for positively determining if the irradiation specimen has been properly located in the specimen container. A second instrument may be used in conjunction with this apparatus for seating the irradiation specimen in the specimen container once visual verification of its location has been made.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
Apparatus for remotely manipulating irradiation specimens comprising: a tubular member having a cap on its lower end and having an opening therein near its lower end; a central rod slidable disposed in said tubular member; a plurality of pivotable grippers attached to said cap and arranged to contact said central rod for gripping an irradiation specimen when said central rod is moved within said tubular member; a camera disposed in said tubular member near said opening for remotely viewing said irradiation specimen; and a diverting mechanism attached to said central rod and arranged near said opening for causing said camera to slide out of said tubular member and into a configuration for viewing said irradiation specimen as said irradiation specimen is being held by said grippers.
Claim 2
Dependent Claim
126 words
Apparatus for remotely manipulating irradiation specimens comprising: a tubular member having a cap on its lower end and having an opening therein near its lower end; a central rod slidable disposed in said tubular member; a plurality of pivotable grippers attached to said cap and arranged to contact said central rod for gripping an irradiation specimen when said central rod is moved within said tubular member; a camera disposed in said tubular member near said opening for remotely viewing said irradiation specimen; and a diverting mechanism attached to said central rod and arranged near said opening for causing said camera to slide out of said tubular member and into a configuration for viewing said irradiation specimen as said irradiation specimen is being held by said grippers.
Claim 3
Dependent Claim
44 words
The apparatus according to claim 1 wherein said apparatus further comprises a thin member disposed in said tubular member and attached to said central rod and said diverting mechanism for allowing said camera to be disposed is said tubular member near said diverting mechanism.
Claim 4
Dependent Claim
44 words
The apparatus according to claim 2 wherein said apparatus further comprises travel limiting means attached to said diverting mechanism and extending through a slot in said tubular member for limiting the travel of said diverting mechanism said central rod relative to said tubular member.
Claim 5
Dependent Claim
32 words
The apparatus according to claim 3 wherein said apparatus further comprises a locking mechanism attached to said tubular member for maintaining said central rod at specific locations relative to said tubular member.
Claim 6
Dependent Claim
36 words
The apparatus according to claim 4 wherein said apparatus further comprises a block attached to the lower end of said central rod for contacting said grippers and causing said grippers to pivot relative to said cap.
