? Integrity under upset conditions
l Cooling of mechanical seals through thermosyphon effect
l Newly-developed Passive Thermal Control Valve to ensure integrity of primary loop through closing control leakage line in several minutes without any supply of power or nitrogen under SBO condition
? Operational safety
l Medium-lubricated guide bearing
? Perfect rotor alignment
l Through Hirth-type serration of connections
? Optimized hydraulics
l Tailor-made impeller/diffuser combination
l Model and full-load performance tests
