INTRODUCTION1.1. INTRODUCTION TO ITER & FUSION FOR ENERGYThe ITER project aims to build a fusion device, twice the size of the largest current devices, with the goal ofdemonstrating the scientific and technical feasibility of fusion power. It is a joint project between the EuropeanUnion, China, India, Japan, South Korea, the Russian Federation and the USA. ITER will be constructed inEurope, at Cadarache in the south of France.Most of the components that make up the ITER project are to be manufactured by each of the participatingcountries and contributed in kind through so-called Domestic Agencies including Fusion for Energy. In manycases the engineering and technologies required to manufacture these components are very advanced.The European Joint Undertaking for ITER and the Development of Fusion Energy or 'Fusion for Energy' is atype of European organisation known as a Joint Undertaking created under the Euratom Treaty by adecision of the Council of the European Union.'Fusion for Energy' has three main objectives:Providing European contributions to the ITER international fusion energy research project being builtin Cadarache, France;Providing European contributions to a number of joint projects with Japan that aim to accelerate thedevelopment of fusion - the "Broader Approach";Coordinating a programme of activities to prepare for the first demonstration fusion reactors that cangenerate electricity (DEMO).

STUDIES TO BE PERFORMEDThe Supplier shall perform 3D FEM thermo-mechanical analyses of the tested geometries in Task 1 only.Correlations shall be used to determine the hydraulic parameters. At the interface Be/CuCrZr the followingparameters shall be calculated: cumulative plastic strain, normal and shear stress, and stress triaxiality.Temperature and VM stress distribution shall be calculated for the whole mock-up. The objective of theseanalyses is to support the understanding of the results of the tests. First an analysis shall be performed foreach geometry to evaluate the expected results in terms of temperature and stress distribution after 5 cyclesand to evaluate the evolution of the drivers of the failure initiation, i.e. cumulative plastic strain, normal andshear stress, and stress triaxiality. After the test, the model shall be modified, after approval of themodifications by F4E, to improve the consistency with the results.The scope of the studies will be further defined at the latest at the KoM.3.1.2.

In caseANSYS is not available, alternative software may be proposed by Supplier to F4E for review andacceptance.3.1.3. TEST PROTOCOLThe general rules, which are applicable to the High Heat Flux testing activity, are described hereinafter.The specified value for the heat flux shall be intended as “target value for the absorbed heat flux” with a flatprofile. A heat flux profile is defined as “flat” when its variation is within ±5% of its average value when appliedonto a flat surface. 1The absorbed heat flux shall be within ±5% of the target value. If, for any reason, this proves to beimpractical, the test operator shall immediately inform F4E of the reasons why the target value cannot beachieved.The tests shall utilise a mask over the required surfaces to ensure a flat beam profile.For Sub-Task 1.2, a 1 MW/m 2 heat flux screening cycle shall be applied to the Be surface area pre and postthermal fatigue phases. The entire area covered by Beryllium on the mock up shall be subject of the highheat flux testing.1 The tolerance of ±5% on the flatness of the heat flux profile should be easily achieved with an electron beam gun.

This document shall describe:The positions of the semi-prototype and the labelling of heated areas for each step of test (thermalscreening and cycling steps),The testing parameters for each position (hydraulics, electron beam),The main measurements which have to be performed during the test,The main probable scenarios of tile failure and the related reduction of the heated surface,All the information required for the execution of the test.3.1.4. TEST PROGRAMME AND CONDITIONSThe identifiers of the components to be tested shall be given at the start of the Task. These identifiers shallbe the basis of monitoring of the individual components throughout their stay at the facility.If so requested by the supplier, the maximum temperature on the surface of the Be tiles may be limited to700 C. No limit below this point is acceptable.

Surface temperature distribution by infrared camera and pyrometers (for e-beam facilities), Internal temperatures at thermocouple locations, Absorbed power values per cycle, Coolant inlet/outlet temperature and pressure, Coolant flow rate, Water calorimetry to measure the absorbed heat flux, Vacuum pressure, Maximum tile temperature, Delta temperature change on a tile during cycling phases, For Sub-Tasks 1.3, and 2.3 an “as run” test history for individual tiles of the semi-prototype shallbe provided.If a failure (any failure of any part of the mock up shall be classed as a failure) occurs: The cycle number and features of failure mode shall be recorded, The heated surface shall be reduced to the tiles without failure. For the Sub-Tasks 2.2 and 2.3, if a hot spot appears, provisions shall be taken so that thedamaged tile is not exposed to further heat load.For the Sub-Task 1.3 and Task 2, the Supplier shall inform F4E when one of the two following criteria is met:Variation of the maximum surface temperature exceeding 20% (measured in °C) between the initialand the intermediate thermal screening and between the intermediate and final thermal screeningduring phases 1 and 2,Appearance of any “hot spot” during fatigue cycling during phases 1 and 2. A hot spot is a specificlocation of the heated surface (generally extending on one or more armour tiles) where thetemperature is higher than the other armour tiles, which are subject to the same heat flux and haveno defects. This hotter region shall be considered as “hot spot” if its maximum surface temperature ishigher than 30% (measured in °C) when compared to the other properly bonded tiles (net of thetemperature difference generated by the related emissivity difference).
