Steam turbine ARABELLE 1000

for power generation

Arabelle nuclear steam turbine improves on the previous generation low pressure (LP) exhaust design with fully independent LP cylinders. By connecting the LP inner casing to an end wall rather than the LP outer casing and ultimately the turbine table, the outer casing no longer needs to act as support.  This simple but powerful design innovation greatly reduces turbine load on the foundation, caused by vacuum variations or condenser forces while improving centering of moving and stationary parts. • Cross-under pipes below the foundation for reduced maintenance duration and costs • Large lay-down areas alongside the LP modules • Easier adjustment of LPs with independent structure • Compact arrangement with fewer bladed rows • A range of last-stage blade sizes for each frequency (50 Hz and 60 Hz) • The largest last stage blade in operation (LSB69) • The largest last stage blade in construction (LSB75) • Proven blade structure with demonstrated reliability • Two, three or four LP modules for excellent back-pressure fit • A compact, powerful, efficient, and reliable turbine • 60% of the power comes from highly efficient single flow expansion • A unique combined HP/IP module • Standard interface/footprint for 50 Hz  and 60 Hz
