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

Click For Summary
SUMMARY

The discussion focuses on the terminology used for handling damaged nuclear fuel, specifically regarding the maintenance vessel Lepse, which is loaded with radioactive waste. Participants debate whether broken pieces of fuel assemblies should be referred to as "debris" or "spillage." Additionally, they discuss the appropriate term for the equipment used to remove fuel assemblies from the ship, considering "retrieval equipment" versus "unloading equipment." The context includes historical incidents involving the Lenin icebreaker, which contributed to the current state of the Lepse.

PREREQUISITES
  • Understanding of nuclear fuel assembly terminology
  • Familiarity with radioactive waste management practices
  • Knowledge of nuclear vessel operations and maintenance
  • Awareness of safety protocols for handling damaged nuclear materials
NEXT STEPS
  • Research "nuclear waste retrieval equipment" and its specifications
  • Study "nuclear fuel assembly damage assessment techniques"
  • Explore "safety protocols for handling radioactive spillage"
  • Investigate "historical incidents involving nuclear icebreakers" for context
USEFUL FOR

Nuclear engineers, radiation safety officers, and professionals involved in nuclear waste management will benefit from this discussion, particularly those focused on the terminology and equipment related to damaged nuclear fuel handling.

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.
http://www.bellona.org/english_import_area/international/russia/civilian_nuclear_vessels/icebreakers/30131

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.
