Part of the Advances in Cryogenic Engineering book series (ACRE, volume 21)


The TRIGA MARK II research reactor in Otaniemi has maximum steady-state power of 250 kW. The reactor peak power at the pulse mode is 250 MW. To study radiation damage processes with this reactor subjected to high fast-neutron flux densities a new low-temperature irradiation device was installed.
