Beryllium Manufacturing for ITER Application in Russian Federation

1. ITER RF DA, Efremov Institute Organization of the works with Beryllium for ITER application in Russian FederationR. Giniyatulin, V. Safronov Workshop on Beryllium Applications and Health & Safety ITER Organization, June 29, 2017

2. Purpose • RF’s FW PA – 40%: • 179 Be-armored enhanced heat flux panels should be manufactured (1.5х1.0х0.2) m • Total armoring area - 270 m2 • Be-thickness - 8 mm • Be-tiles dimensions– (50х16x8) mm • Total weight of the Be-tiles - 4 t ~40 fingers per panel ~ 700 m2 of Be-armoured FW panels, ~ 10 tons of Be-tiles Castellated tiles (16x50x8) mm N~ 325 000

3. Organization structure of the works for EHF FW PA SC ROSATOM ITER RF DA Works with Berylium NIKIET JSC Efremov Institute JSC Bochvar Institute: Beryllium TGP-56FW technology development FSUE Bazalt: Beryllium TGP-56FW manufacturing (blocks and tiles) JSC Kompozit: Beryllium tiles cutting from S-65 blocks

4. Be-tiles manufacturing • Two beryllium grades are using in RF for the tiles manufacturing: • TGP-56FW: initial material – vacuum melted beryllium ingots from Ulba plant • S-65 tiles: initial materials - VHP blocks from Materion TGP-56FW technological line Pressing of the billets Be ingots Powdering Powder separating Cleaning/ Packaging Wire EDM for the tiles Chemical etching of the tiles S-65 technological line Vacuum Hot Pressed billet Wire EDM for the tiles Chemical etching of the tiles Cleaning/ Packaging

5. Pilot batches of Be tiles TGP-56FW S-65 Beryllium ingots VHP billet ø 520, H 230 mm VHP billets 220x220x60 mm VHP billet ø 300, H120 mm Tiles 16x50x8 mm castellated Tiles 16x50x8 mm castellated

6. The types of work with Beryllium during FW manufacturing in RF

7. Basic documents applied for beryllium safety in RF • Sanitary rules «СП 46-83 - Design and operation of enterprises for the production and processing of beryllium and its compounds» • Sanitary rules «№993-72 - Medical regulations for working with beryllium and its compounds» • Methodological instructions «МУ 2.2.1.25 – 06 Hygienic requirements for design and operation of enterprises for the production and processing of beryllium and its compounds»

8. Be-contamination conditions for RF suppliers * - The premises with periodic stay of the staff ** - The respiratory protection required if Be in airborne Be >0.2 µg/m3 or if Be at surface >30 µg/m2
