The VVER-440-type plants differ considerably from western-type pressurized water reactors (PWR). The two main distinguishing characteristics are horizontal steam generators and loop seals in both hot and cold legs, which are lately a great safety concern worldwide. In 1987, the International Atomic Energy Agency (IAEA) organized and sponsored one of the tests performed on the Hungarian PMK-NVH test facility and called it IAEA-SPE-2. The test was chosen from a wider test matrix performed to investigate emergency core cooling system capability in VVER-440 plants for a small-break loss-of-coolant accident (SB LOCA). PMK-NVA is a one-loop, full-height, full-pressure model of the Hungarian Paks nuclear power plant, type VVER-440, Soviet production. The facility power level is 100%, according to the 1:2070 scaling factor.
