OKB “GIDROPRESS” HAS COMPLETED PPI ACCEPTANCE TESTS
OKB “GIDROPRESS” has completed acceptance tests of eight pitch position indicators (PPI) for Kalinin NPP Unit 1. The indicators were designed at OKB “GIDROPRESS” and manufactured at its production facilities. The indicator is a component of the control and protection system (CPS) drive ShEM-3 and serves to monitor the position of the VVER-type reactor CPS absorbing rods. The PPI acceptance tests were performed on the hot running-in benches V-1000 and V-1000-2. The hot running-in benches are intended for life-, qualification-, routine- and acceptance testing of VVER-type reactor components under thermal-hydraulic conditions, maximally close to actual conditions.
