The bow deformation of fuel rod usually occurs in Pressurized Water Reactor (PWR). As the
flow channel in fuel assembly changes due to the bowing, coolant in subchannels is …

The validation process is done to ensure the performance of nuclear codes compared to
experimental results and to determine the degree of reliability of codes output. The …

The effect of assemblies bowing in PWR nuclear reactors onto core neutronics is an
observed phenomenon still poorly understood which can lead to Power Ratio Tilt. Studies of …

Abstract The Lateral deformation of Fuel Assembly (FA) under the operational conditions of
the reactor cores is called FA bowing. This phenomenon is caused by factors such as …

Fuel assembly bow has been increasing in Ringhals 3 and 4 since 2012/2013. To get a
better understanding of this development a new measurement device was taken in use in …

The calculations performed for the design and operation of a Nuclear Power Plant (NPP) are
a key factor for their safety analyses. The standard for the computational analysis of NPPs is …

Neutron noise analysis has been done over the last decades to predict fuel assembly and
pressure vessel vibrations to evaluate safety related issues. In order to have a better insight …
