  2. HiRadMat: General information - naming Agenda S. Evrard

  3. HiRadMat: WG2 – WANF Dismantling Work packages - tasks

  4. HiRadMat: WG3 – Irradiation Area Work packages - tasks

  5. HiRadMat: Safety • Met Luca BRUNO (BE/RSO) • Met Ghislain ROY (BE/DSO) • Met John PEDERSEN (EN/DSO) • Met Thijs WYNANDS (EN/RSO) • Safety file : template + how to fill in it • DIMR : template + how to fill in it • ALARA committee : how to trigger it • Various comments got : • Civil engineering assessment on tunnel structure • OK for access to WANF area in W46 • Transport resources • RP workshop in 867 : make an area request if needed

  6. Safety : DIMRhttps://edms.cern.ch/file/1016021/1/DIMR_nivII_FR_v1.0.pdf DIMR

  7. Cooling and ventilation SPS - AIR FLOW

  8. Cooling and ventilation TNC - AIR FLOW

  9. Cooling and ventilation NEW FACILITIES Existing ventilation and cooling facilities were dedicated to WANF area (separated from SPS ones). They are out of order and cannot be refurbished or upgraded. Air ducts : inspection next week + decision Timescale : Final spec. required in April’10 for start of activities in Nov’10 Design parameters: direct cooling or via exchanger, water type, power, DP, Pmax, T° range, DT°,… To be addressed : dew point, under pressure, safety mode (urgent access, smoke removal,…) Evacuation exit : overpressure = additional & redundant units WP : 4 WU’s identified

  10. Transport • 4 WU’s Identified: • PR532 repair: VIC + work procedure done. Work in W46&47 • Special tooling studies (automatic hook-study in progress,…) • WANF dismantling • T1 dismantling (TBC) • Resources management (ALARA) • First estimate: team of 6 crane drivers / 20 people involved • Remote camera’s: existing system (4 units)

  11. WANF dismantling Template Doc. • Dedicated meeting on Wednesday 04/11. • Consultancy to certified company • Decontamination first (January 2010 ?) • Difference between material and waste • Waste Storage in ISR6 or evacuation by container (ANDRA) • Inventory available:\\cern.ch\dfs\Workspaces\h\HiRadMat\WG2_WANF Dismantling\Material Inventory\ • For each item, detailed procedure to be worked out : • Equipment designation (Magnet, Beam instrumentation, vacuum,…) • Owner • Destination : waste or material, ISR6 or ANDRA • Handling means (special tooling, trailer,…) • Dismounting procedure (drawing, Technical data) • DdD estimate, measurement,  study group to be launched (Dino, Michael, Serge, Yvon)

  12. HiRadMat: EDMS and drawings Required drawings • EDMS : https://edms.cern.ch/nav/CERN-0000079274 • The view of the TNC tunnel : top and side, indicating the T9 target height and the decay tube. • A sketch of the TNC tunnel, the decay tube and the downstream V0 pits – just distances would be sufficient. • A zoom (top and side view) of the foreseen irradiation area indicating the distance from the T9 target front shielding • A general 3D view of underground +surface areas (TNC-TCC6 and TT61 + shaft and BA7 + crane, elevator and BA7 door)

  13. HiRadMatProject Action list S. Evrard
