At AREVA’s integral test facility INKA, different passive safety systems of the generation III+ boiling water reactor KERENATM are being tested. For the detailed analysis of condensation phenomena, an improved understanding and quantitative assessment of the occurring two-phase flow phenomena is essential. In this paper, we describe the special instrumentation of the INKA test facility with high-temperature high-pressure thermo needle probes and a special multi- channel gamma densitometer. The paper gives a short overview of the passive safety concept of the KERENATM system, the fundamentals of the special instrumentation and discusses some experimental results from the INKA test facility in Karlstein.
