WP6 coordination meeting #4

Thursday 15 May 2025, 15:00 → 16:25 Europe/Zurich

CERN

General (Claudia)

• Please check open actions under the JIRA WP6 board: WP6 - RP & Safety - Agile Board - CERN Central Jira
• For any actions under your responsibility, please let me know if you have any updates
• In case of any changes to the board, don’t hesitate to contact me

 

Safety (Melania not present)

 

RP (Claudia)

• FLUKA model to be updated with WP8 once SHiP provided input on muon shield
• BDF
• Olin has performed soil activation studies for NA62 and various BDF shielding configurations. Once discussed with Claudia, a meeting will be scheduled with Pavol. The preliminary irradiation station shielding might be affected by it
• Olin has performed further studies for the service cell to increase statistics and reduce the roof shielding thickness. Action/Claudia to investigate dose rate limit to be applied on roof
• Action/Olin to perform activation studies downstream of BDF once muon shield has been updated
• Action/James to potentially work on BDF FLUKA model improvement and fluence spectra scoring for radioactive transport and waste considerations. A target diameter of 25 cm to be used as causing highest activity concentrations. Ta cladding to be included
• Elzbieta has performed further TCC8 dismantling studies for the target station and the TAX, separating the items according to drawings from Nicolas. Action/Ela to put fluences to CERNBOX once available. Ela also added new cooling time for July 2028 to the inventory list
• Angelito informed that excavations for TT7 shielding recovery will start on 19/05. For the moment, no place for the shielding blocks cleaning and painting has been identified. Action/Claudia to check with Francois to urgently identify a place.
• Target material for prototype tests not ready in time requiring a delay of the installation after the TS. Yann investigated dose rates of PMIs and proposes a 16 h cool-down and a dose rate on the PMI next to the setup of < 2 mSv/h. Action/Yann to write an email to the relevant person
• NA62 dismantling inventory list has been provided. Action/Yann/Renaud to provide information on radioactive waste zoning

 

RP transport/waste (Philippe/Luca/Fred)

• Transport container dimensions for the TCC8 dismantling were provided by Philippe
• LS3 waste forecast for HI-ECN3 should be ok

 

FIRIA (Rahul, Oriol)

• See slides about relevant updates

 

Access & Safety Systems (Boris)

• An access system was not yet foreseen for the BDF partition. Action/Boris current WP4 plans and requirements from RP/FIRIA/Safey to be collected
• Boris informed about an upcoming change in the sub-WP management. Details to be transmitted once known

 

Occupational health (Jamie)

• See slides about relevant updates
• The funding for the new tent has not been approved. Alternatives are being investigated. Main constraint during LS3 comes from the NA62 dismantling
