<strong>Annex</strong> BIDM # F4E_D_24W3JRCall # F4E-OPE-400 (IV-PT)Page 4 / 35 Rev. 1.131.2. SUBJECT OF THIS TECHNICAL SPECIFICATIONThis Technical Specification applies to the performance of high heat flux (HHF) testing of the Be/CuCrZr/SSFirst Wall (FW) and Faraday Screen (FS) mock-ups manufactured by a fabrication route where bondingbetween the different materials (essentially SS, CuCrZr and beryllium) is obtained by using the HIPpingtechnology.The overall testing activity is subdivided into 2 tasks:Task 1: For a first set of 3 mock-ups, the objectives of these tests are to determine mock-up performanceunder thermal fatigue in support of the development of an Enhanced Heat Flux (EHF) FW design.Task 2: For the mock-ups belonging to the 2 nd set, the objectives of these tests are to qualify the design of theFS of the ICH&CD antenna, through thermal fatigue tests. The mock-ups will be provided by F4E at differentperiod of time in the course of this contract.See appendix 1 for a tentative time schedule, giving to tenderer an indication of when the various tests couldpossibly take place.

GENERALThe Supplier shall perform a series of High Heat Flux (HHF) tests on small scale mock- and semi-prototypes,subdivided in the 2 following Tasks:‣ Task 1 : First Wall mock-ups and semi-prototypeoooSub-Task 1.1: HHF testing of 1 small scale heat sink mock-up, made of SS and Copperalloy, to determine the performance of the heat sink designSub-Task 1.2: HHF testing of 1 small scale Be-coated mock-up to determine theperformance of the EHF design under thermal fatigue,Sub-Task 1.3: HHF testing of 1 Be coated semi-prototype to determine the performance ofthe EHF design under thermal fatigue with cycles and heat loads as defined below,‣ Task 2 : Faraday screen of the ICRH antennaoooSub-Task 2.1: HHF testing of 2 small scale mock-ups, made of SS and Copper Alloy, todetermine the performance of the heat sink design,Sub-Task 2.2: HHF testing of 2 Be coated Small Scale Mock-Ups to determine theperformance of the FS design under thermal fatigue,Sub-Task 2.3: HHF testing of 1 Be coated FS prototype assembly to determine theperformance of the FS bars and attachments under thermal fatigue.2.1.2. SERVICESThe proposed work shall include the following activities:‣ 3D FEM thermo-mechanical analyses of the configurations tested in Task 1 (estimated at up to 4man months), including final comparative studies between the experimental and theoretical results,‣ Performance of screening tests and calorimetry on test samples of Beryllium to determine preciselythe emissivity and the absorption coefficient of beryllium surface under different conditions of surfaceand of temperature,‣ Preparation of the mock-ups prior to testing, including in particular the installation of thethermocouples as specified in the mock-up drawings,‣ Storage of the mock-ups in clean and dry conditions prior to and after testing, up to 6 months,‣ Performance of screening tests and calorimetry at the required test conditions to ensure the accuratemeasurement of the absorbed heat by the mock-ups,
