... The following activities help ensure safe storage: • Certification of fuel rods using nondestructive examination techniques • Thermal testing of fuel rods • Intermediate nondestructive examinations of fuel rods between several successive tests (if they are performed) • Material science examinations of fuel rods after testing Figure 1 depicts the equipment for testing under dry storage conditions.

... The performance capabilities of the equipment are as follows: • Test temperature range of 300 to 600°С • Remote loading and unloading of fuel rods • Simultaneous testing of up to 18 irradiated full-size fuel rods from VVER-1000 reactors in three independent modules • Concurrent simulation of several storage conditions for spent nuclear fuel both in gaseous media and temperature • Recurrent gas sampling in any module • Profiling of the temperature field throughout the height of the fuel rod • Temperature cycling (simulation of daily or seasonal variations in ambient temperature) • Nonuniformity of axial temperature distribution along the height of no more than ±3 percent, and nonuniformity of radial temperature distribution in the capsule of no more than ±2°C.
