Christmas Light
’Twas the night before Christmas when all through the house
No electrons were flowing through even my mouse.
All devices were plugged by the chimney with care
With the hope that St. Nikola Tesla would share.

The swelling of mixed oxide in fuel elements irradiated within the irradiation program of the German Fast Breeder Project was determined. In fuel pins with a burnup-independent high power level, a constant swelling rate of 0.5% per percent burnup was found at burnups above 4%. It is concluded that this swelling rate is induced by solid fission products. The volume-averaged swelling due to fission gases seems to be saturated at a value of ∼6%.
