Neutronic Impact of Pressure Tube Creep in a CANDU Lattice
- 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)
Description
In the CANDU reactor, the coolant channel diameter increases due to the pressure tube creep resulting from neutron irradiation damage. Along with the creep, the pressure tube also undergoes a slight sagging phenomenon. It is well known that a crept pressure tube leads to a non-uniform coolant flow causing a concern in the fuel cooling. In this work, the pressure tube creep was evaluated from the neutronic point of view with the HELIOS code. Impact of the crept pressure tube is evaluated in terms of the lattice reactivity, void reactivity, pin-wise power, atom density of plutonium isotopes, and fuel temperature coefficient
