“…As the property library for LLE in RELAP5-3D has an upper threshold of 40 bar, it was not possible to directly use this version of the code. The numerical simulations confirmed that the modified version of the RELAP5 code was able to accurately predict the pressure trends of an In-box LOCA occurring in the HCLL TBM (Test Blanket Module), with an average discrepancy of about 3 bar (over a maximum experimental pressure of about 52 bar) [28].…”

“…Eleven tests were carried out, varying the injection duration, the injection area (9.5•10 -5 m 2 and 1.3•10 -5 m 2 ), the He pressure, the actuation of the isolation valves and the opening pressure of the rupture disk. Further details on the two experimental campaigns can be found in [28], [45].…”

In-box LOCA was identified as one of the worst accidental scenarios for the HCLL TBS (Helium Cooled Lithium-Lead Test Blanket System). Aiming to experimentally analyze the consequences of this transient, ENEA designed and built THALLIUM (Test HAmmer in Lead LIthiUM), a facility that reproduces the LiPb loop of the HCLL TBS. Two experimental campaigns were carried out by simulating the rupture of a stiffening plate and the related helium injection in the LiPb loop. The obtained experimental data were used to check the capabilities of RELAP5 system code to reproduce the pressure wave propagation that follows this accident. The first simulations were made with RELAP5-3D using LBE (Lead–Bismuth Eutectic) as a system fluid, as the thermophysical properties of LiPb are tabulated only up to a maximum value of 40 bar in this version of the code. Then, LiPb properties were implemented in RELAP5/mod3.3, after selecting the proper correlations from a literature review. This work summarizes the numerical simulations of the second experimental campaign, which was simulated with both versions of the code. The simulations highlight that the code is able to accurately reproduce the experimental results and that RELAP5-3D is slightly more precise than RELAP5/mod3.3 in predicting the pressure trends.

“…IELLLO (Integrated European Lead Lithium LOop) facility was used in the past to characterize the performances of a Vortex flow meter and of absolute pressure transducers [2]. Then, the absolute pressure transducers were tested at higher pressures in the experimental campaigns that aimed to simulate the consequences of an In-box LOCA for the HCLL TBS (Helium Cooled Lithium-Lead Test Blanket System) [3]. A guided-microwave level meter was also successfully tested in these campaigns.…”

The experimental facility IELLLO was installed in ENEA Brasimone R.C. in 2007, aiming to support the design of liquid Test Blanket Modules that will be installed in ITER and to contribute to the development of Lead-Lithium Eutectic (LLE) technologies. IELLLO has been recently upgraded by installing instrumentation relevant for ITER application. Differential pressure transducers, a Coriolis and a thermal mass flow meters were installed in the facility. An experimental campaign was planned, setting two objectives. The first objective was to qualify the instrumentation for flowing LLE The installation of a differential pressure transducer across each flow meter made also possible to characterize the pressure drops across these instruments. The second objective of this activity was to improve the results of the 2015 campaign by analyzing the performances of the main components of the loop at lower mass flow rates (namely 0.5-1.2 kg/s) and by quantifying the pressure drops across the main components. The investigated flow rates were chosen to be relevant for the LLE loop of the WCLL TBS (Water Cooled Lead-Lithium Test Blanket System). This work presents the results of the experimental campaign, paying particular attention to underline the lessons learned on how to correctly operate instrumentation for LLE.
