The document deals with the description of results obtained by the Relap5 code in post-test analysis of the test SB-CL-18 performed in the Pressurized Water Reactor (PWR) experimental simulator LSTF installed at the Tokai-Mura JAERI Research Center in Japan. The Relap5, now in the version Relap5/Mod3.2, is the well-known computer code developed at Idaho National Laboratory in US: the code is in use at UNIPI since about two decades (all code versions). The LSTF loop is an Integral Test Facility (ITF) simulating with full height, full pressure, full linear power a US type 4-loop Westinghouse PWR. The concerned test was adopted as basis of the International Standard Problem (ISP) 26 by The Organization for Economic Cooperation and Development / Nuclear Energy Agency / Committee on the Safety of Nuclear Installations (OECD/NEA/CSNI) and was already analyzed at UNIPI by using the Realp5/mod2 code versions. The results obtained by the current code version are used for the constitution of the database of errors for CIAU and for the qualification of the methodology (first target).

Abstract
The document deals with the description of results obtained by the Relap5 code in post-test analysis of the test SB-CL-18 performed in the Pressurized Water Reactor (PWR) experimental simulator LSTF installed at the Tokai-Mura JAERI Research Center in Japan. The Relap5, now in the version Relap5/Mod3.2, is the well-known computer code developed at Idaho National Laboratory in US: the code is in use at UNIPI since about two decades (all code versions). The LSTF loop is an Integral Test Facility (ITF) simulating with full height, full pressure, full linear power a US type 4-loop Westinghouse PWR. The concerned test was adopted as basis of the International Standard Problem (ISP) 26 by The Organization for Economic Cooperation and Development / Nuclear Energy Agency / Committee on the Safety of Nuclear Installations (OECD/NEA/CSNI) and was already analyzed at UNIPI by using the Realp5/mod2 code versions. The results obtained by the current code version are used for the constitution of the database of errors for CIAU and for the qualification of the methodology (first target).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
