Fuel management


At the end of 2008 a transition procedure from the old Russian designed TVS-M fuel assemblies to the advanced TVSA fuel type was accomplished at Kozloduy NPP WWER-1000 Units 5 and 6.

The TVSA assembly distinguishes itself with much stronger construction and using a mixture of uranium and uniformly distributed Gd as a burnable absorber in 6 or more fuel rods.
