Abstract EN
This paper presents the assessment of CATHARE 3 against PWR subchannel and rod bundle tests of the PSBT benchmark.
Noticeable measurements were the following: void fraction in single subchannel and rod bundle, multiple liquid temperatures at subchannel exit in rod bundle, and DNB power and location in rod bundle.
All these results were obtained both in steady and transient conditions.
Void fraction values are satisfactory predicted by CATHARE 3 in single subchannels with the pipe module.
More dispersed predictions of void values are obtained in rod bundles with the CATHARE 3 3D module at subchannel scale.
Single-phase liquid mixing tests and DNB tests in rod bundle are also analyzed.
After calibrating the mixing in liquid single phase with specific tests, DNB tests using void mixing give mitigated results, perhaps linked to inappropriate use of CHF lookup tables in such rod bundles with many spacers.
