Abstract

Apparatus for remotely obtaining sample scrapings from the inner surface of a fuel channel of a nuclear reactor with coolant in the fuel channel. A
sampling tool is introduced into a fuel channel. The sampling tool has a cylindrical casing in which are mounted cutters for obtaining the scrapings. Forward movement of a central shaft in the sampling tool actuates the cutters in sequence to project through a slot as they move forwards and the sample scrapings fall into sample receiving pockets in the sampling tool. A
pusher having a cylindrical casing of substantially the same inner diameter as the inner diameter of the fuel channel has a floating plunger mechanism with a sliding internal housing mounting a plunger rearwardly biased in the housing. The ram head of a fuelling machine engages the trailing end of the plunger, moves the housing forwardly until it stops against the casing of the sampling tool and then advances the plunger to cause forward movement of the central shaft of the sampling.
tool to obtain the scraping.
A preferred form of the apparatus obtains sample scrapings at desired orientations. For example, it obtains scrapings at desired ones of a 11:00 o'clock, 12:00 o'clock or 1:00 o'clock orientations. An orientation device is installed in the end of a fuel channel and it has a rotatable ring which may be rotated to one of three selectable positions corresponding to respective ones of the 11:00 o'clock, 12:00 o'clock and 1:00 o'clock orientations: A ring key on the orientation device cooperates with a keyway in the sampling tool to orient the sampling tool.
