AN EVALUATION OF COBRAⅢ-C AND SABRE-I (WIRE WEAP VERSION) COMPUTATIONAL RESULTS BY COMPARISON WITH STEADY STATE DATA FROM A 19-PIN INTERNALLY GUARD HEATED SODIUM COOLED BUNDLE WITH A SIX-CHANNEL CENTRAL BLOCKAGE (THORS BUNDLE 30)

摘要

The predicted computational results of two well-known sub channel analysis codes, COJ5RA III-C and SABRE-1 (wire wrap ver¬sion) , have been evaluated by comparison with steady state tem¬perature data from the THOKS Facility at ORNL. Both codes give good predictions of transverse and axial temperatures when com¬pared with wire wrap thermocouple data. The cross flow velocity profiles predicted by these codes are similar which is encouraging since the wire wrap models are based on different assumptions.
