Results of the pressure drop vs. coolant flow measurement in the mockup of the irradiation channel.
Fig. 2
One-dimensional code validation. Measured to computed temperature differences as a function of the rig power. Note that the last point on the horizontal axis is out of the scale.
Fig. 3
Result of the 1D heat transfer calculation of the ISHTAR rig. The dimensions of the layers in the radial direction are marked approximately.

ISHTAR thermostatic rig overview.
Fig. 7
Allotted irradiation locations for the ISHTAR irradiation rig in MARIA reactor core marked in green. The scheme covers the core without the reflector blocks. The fuel elements are marked with dark gray circles, e.g., j-5.
