Abstract

Dependence of gas gap properties on bu
rnup has been obtained with use of
TRANSURANUS [ 2] code. Implem
ented dependency on burnup is based on
TRANSURANUS calculations of different fuel pins upon different linear power Ql. Obtained
dependence was implemented into DYN3D ¹ code and results of new dependence effect on
characteristics of WWER fuel loadings are presented.
The work was perform ed in fram ework of orders BMU SR 2511 and BMU R0801504
(SR2611). The report describes the opinion and vi ew of the contractor ? SSTC N& RS – and
does not necessarily represent the opinion of the ordering party – BMU-BfS/GRS and T?V
S?D.
