(TS)

What do you think about the risks to make it difficult to take out the rest of fuel assemblies, such as disfigured rack by explosion or corrosion of channel box etc..

 

(Happy11311)

There are various risks but disfigured rack or sticking can be managed. The biggest risk is corrosion. The worst senario is fuel assemblies are released from channel box to have channel fastener taken off because of corrosion. There is no contingency plan for it at this moment.
