3. DESCRIPTION OF TEST FACILITY - OTIS is a 1:1686 volume-scaled single loop (one hot log and one cold leg) facility with critical elevations preserved. The single once-through steam generator contains 19 tubes prototypical of a B&W PWR plant. The electrically heated core has a power capability of 180 KW which is representative of 10 per cent scaled power based on a 2584 MWth plant. It contains no primary pump but all other active components are simulated and it operates at full PWR system pressure.


4. DESCRIPTION OF TEST - Two-phase natural circulation and reflux.


5. EXPERIMENTAL LIMITATIONS OR SHORTCOMINGS -


6. PHENOMENA TESTED - Natural circulation in 1-phase flow; boiler condenser mode; leak flow; heat transfer in covered core; non- condensable gas effects; intermittent two-phase natural circulation; natural circulation in core, vent valve, downcomer; superheating in secondary side.
