Room: 892/1-B09 - EN-AA (D. Raffourt) will make a proposal for the siren extension and associated cable request. Action/Michael to follow up - As the siren extension impacts the schedule for works in TCC8 (low activity part, access container installation), dates should be communicated as soon as possible to WP4/5/6 and planning (Ixone/Fernando). - Action/Michael CAF positions were defined. Action/Rahul to check for reference and share it with team

BDF study update

Radioactive waste update

• Frederic Lionel Aberle (CERN)
• Paolo Giunio Pisano (CERN)

Room: 892/1-B09 - News TCC8/ECN3 dismantling - News BDF target studies - Action/Fred to check with Gerald/Paolo if Inconel to be separated from W/Ta target for waste packaging - Action/Yann/Renaud to do waste forecast update

FIRIA update

• Rahul Kallada Janardhan (HSE-OHS)

Room: 892/1-B09 - Action/Pavol to make statement for FIRIA that filter burning scenario for filters from the target complex (not He circuit) does not have to be considered Underground fire doors were foreseen in NA-CONS, but not above-ground that were included in the IRP. - Action/Rahul to organize a visit with SCE to discuss compartmentalization

Access & Safety Systems

• Michael Dole (CERN)

Room: 892/1-B09 - Action/Michael to check with Ixone for date of b911 reader installation which should be installed as soon as possible (October 2025?) - Action/Michael to follow up with Pablo on review of proposed access systems in b574 as not in line with area classification (mostly all Controlled Radiation Area!, EDMS 3309739). Only first/second floor rooms accessible from the outside are with card readers. Turnstile for unicity control in corridor as extra dosimeter reader. Only normal groundlevel access at changing room area. All others are emergency exits only. Large door from b911 to b574 is with RP veto. Don’t hesitate to contact Claudia for any questions - For access container, fence is already in TCC8 with minor modifications being handled under WP4. Action/Jean-Louis to share location with Michael, and extend container time frame - Service cell design study covers fire detection system, which is communicated by WP4 to EN-AA once available (~end of year) - Action/Michael to schedule meeting with Rahul and Oriol to follow up on open questions regarding underground fire system requirements that represent 80% of their total cost - Action/Michael share planning with Ixone and Fernando Once discussed updates (e.g. on access system were done), Action/Michael to distribute EDMS for review
