PIV Measurement of Velocity Distribution in the Moderator Circulation Test (MCT) ()
Abstract
Korea Atomic Energy Research Institute
(KAERI) has been carrying out a scaled-down moderator test program to simulate
the CANDU-6 moderator circulation phenomena during steady state operation and
accident conditions. The Moderator Circulation Test (MCT) facility was designed
and constructed as 1/4 scale of the prototype of CANDU-6 reactor. In the
present work spatial distribution of two-dimensional velocity in the MCT
facility under isothermal condition was measured using planar Particle Image
Velocimetry (PIV) system which consists of double pulsed laser, synchronizer,
and high speed camera. TSI’s Insight TM 4G software was used to perform PIV
image capturing, PIV calculation and post processing. 10 μm sized silver-coated
hollow sphere particles were used as flow tracer particles. Multiple
experiments were conducted to cover large area of the MCT facility with limited
field of view of a single camera. Instantaneous and averaged velocity field
were analyzed for each spatial position and flow rate. This research is capable
of offering validation data for self-reliant CFD tools to predict moderator
subcooling margin in CANDU-6 reactor.
