Resistance to Grid-to-Rod Fretting: Twin Grids in 14ft – 4 loop reactor
Beginning of the 2000’s, AREVA experienced grid-to-rod
fretting of AFA 2G fuel assemblies in some 17x17 14 ft
GTRF issue occurred after GEMMES fuel management implementation
in the14ft 4 loop plants (Fuel assembly burnup Increase)
Higher axial flow rate (+14%) and higher transverse flow (+60%) in the
first span of the fuel assembly in a 14ft 4 loop plant
Only at the bottom grid level
Development and Implementation of the “twin grid”
concept on the 14 ft designs in 2002
14 ft AFA 3G design has not been concerned any more by GTRF
As of May 2012, more than 8,300 fuel assemblies were irradiated in 23
14 ft plants

Resistance to FA deformation: Monobloc® Guide Tube and Hold Down
system Optimization
Mid of the 90’s, AREVA experienced severe fuel assembly
distortions of AFA 2G fuel assemblies with 17x17 designs
Extensive fuel assembly bow measurements (14,000 available as of
December 2010) to support understanding program and modeling
Systematic rod drop time measurements at end of each cycle
Prompt implementation of a thick MONOBLOC® guide tube with
appropriate Hold Down spring force reduction
As of May 2012, more than 26,500 fuel assemblies are made of MONOBLOC®
guide tubes
These improvements reduced the in-core deformation by about a factor 2

Move to the AFA 2G grid design
Improvement of the vane size and pattern
Capability to meet higher CHF performance request
Move to Zy4 low tin cladding and anti-debris nozzle from 1991
Increased burn-up and high duty conditions required cladding with higher
performances with regard to corrosion
At that time, debris fretting brought about most of the cladding failures
