Benchmark Testing the ODEN CHF Loop to Columbia University HTRF

Abstract

Westinghouse has designed and built ODEN, a new Critical Heat Flux (CHF) test loop for PWR applications. It is located at the Westinghouse Thermal-Hydraulic Test Facility in Västerås, Sweden. ODEN can accommodate full length (4.3 m) bundles, up to 6x6 rod arrays, up to 16 MW power, and accurately cover a wide range of PWR thermal-hydraulic conditions. Benchmark qualification CHF tests at ODEN were recently performed. Results indicate good agreement between CHF data from ODEN and data from HTRF. Repeatability (ODEN – ODEN) was also good. This paper presents the details of the comparative tests and the resulting data analyses.
