High Temperature Irradiation (Planned)<br />

• Motivation<br />

– Radiation damage is controlled by a thermally<br />

activated processes, so some temperature<br />

control is desirable<br />

• Planned Work<br />

– Neutronics/gamma heating calculations<br />

– Thermal hydraulics calculations (safety case)<br />

– Can design and T&C specifications<br />

Muroga (2001)<br />

OPAL contains empty space (“hot<br />

source”) in the RPV. By developing a<br />

suitable holder (such as the ORNL<br />

HFIR sample heating holder, left),<br />

samples may be irradiated in OPAL at<br />

higher temperatures, thereby enabling<br />

elevated-temperature damage mechanisms<br />

to be characterised.
