A study was undertaken to identify means to achieve reactor vessel life extension goals for Zion units 1 and 2. Neutron flux reduction measures were examined, which included fuel management methods. The low-leakage loading pattern L {sup 4}P fuel management schemes have been implemented at both Zion units 1 and 2, and unit 1`s scheme has been augmented with hafnium absorber assemblies in order to meet fluence reduction goals. The desired flux reduction factors are being achieved with no discernible deleterious operational impact. Use of these fuel management schemes to reduce neutron fluence allows a decision on vessel internals modification to achieve life extension goals to be delayed.
