Preliminary results on the development of a fast-neutron tomography system for void fraction distribution measurements

There has been a continued desire to include more physical phenomena and mechanistic treatment in the prediction of Critical Heat Flux (CHF) for decades. A major impediment to these efforts is the lack of local measurements at CHF location, as typical instrumentation employed in these full-scale experiments only involves wall temperature measurements and at best a few point measurements of void fraction. There is a need to have subchannel (or …
