OKB “GIDROPRESS” shipped VVER equipment components to Rostov NPP
OKB “GIDROPRESS” shipped a set of hold-down devices to Rostov NPP Unit 4. The set includes 24 elements. The pressing devices are used in the top head unit of VVER-type reactor. The hold-down devices are intended to force down the reactor internals in order to prevent their vertical movement due to coolant flow during reactor operation. These devices prevent vibration of the reactor internals under reactor plant power operation and provide reliable holding down of internals in the reactor. The hold-down device is designed at OKB “GIDROPRESS and manufactured at its production facilities. The shipping of the equipment has occurred before the planned schedule and without any remarks.
