Research Abstract:
The Generalized Linear Least-Squares Cross-Section Adjustment 
methodology, used in criticality safety problems can handle prior 
parameter correlations and prior response-parameter correlations. In 
this work the two parameters one response model of the generalized 
linear least squares parameter adjustment methodology was used in 
order to analyze the procedure of improving cross sections agreement 
with integral experimental results by tuning. The tuning procedure 
can be achieved by modifying only one parameter, for instance the 
modification of v in ENDF/B-VII.0, in order to improve 
agreement of calculated responses with corresponding integral 
measurements results. The two parameters one response model formulas 
will be presented and reduced to a tuning simulation mode, analyzed 
and illustrated by a criticality numerical example. (Trans. Isr.
