Abstract
The SCANAIR code, developed by the Institut de
Radioprotection et de Sûreté Nucléaire (IRSN), is
designed for modelling the behaviour of a single fuel rod
in fast transient and accident conditions during a
reactivity initiated accident (RIA) in pressurized water
reactor (PWR). In SCANAIR, the available fuel material
properties and the thermal-hydraulics (TH) model are for
PWR fuel and coolant conditions, respectively, but the
code does not have similar models for boiling water
reactor (BWR) to be applied in BWR RIA, the rod drop
accident (RDA). Thus, the code lacks material properties
of Zircaloy 2 (Zry-2) which is the cladding material in
BWR fuel rod. Up until now, the only Zry-2 models
implemented into the code are the laws for yield stress
(YS) and ultimate tensile stress (UTS) of irradiated
cladding from a bibliographic study, and the laws have
not been validated with SCANAIR. New YS and UTS laws are
now fitted based on PROMETRA mechanical tests and
implemented into SCANAIR
