What's the Best Term for Damaged Nuclear Fuel Handling?

[Jack8rkin]

Hello everyone!
Anybody deals with nuclear waste?
I got a question about the maintenance vessel Lepse, which is fully loaded with radwaste.
Here is a link:
http://www.bellona.org/english_import_area/about_bellona/33320
There are many cases (or tubes) containing one spent fuel assembly each, as well as caissons (basically tube-like containers) filled with several damaged fuel assemblies each.
The assemblies are in bad condition and, as I understand, some parts are broken off of them, some fuel is spilled.

1. What would you call the things that are broken off the FAs, including nuclear fuel?
Is it "debris" or "spillage"?

2. What would you call the eqipment to remove the fuel assembleis from the ship?
Is it "retrieval equipment" or "unloading equipment"?

Please, share your experience.

Thank you

Apparently Lepse contains spent fuel from the Lenin icebreaker.

Lenin had 3 PWRs producing 90MW. The assemblies are likely relatively small, but probably of high burnup (which means a lot of fission products).

Apparently there were "two accidents onboard the nuclear powered icebreaker Lenin. The first took place in February 1965, when Lenin was undergoing repairs and refuelling. The vessel sustained severe mechanical damages to the fuel assemblies, some of which were broken in two pieces, and were detected during the unloading of fuel from reactor number two. About 95 spent nuclear fuel assemblies were transferred to the nuclear service ship Lepse and unloading was halted after that. "

So Lepse contains 'damaged fuel'. Ostensibly, it would require special 'fuel handling' equipment to retrieve and safely disposition the fuel.
