Updates/progress

Progresses in the CE drawings based on latest discussions about ventilation system and safety aspects

Trench integration progressing taking into account RP constraints Discussions on-going with HE to maximize vertical

movement of the shielding blocks and apply ITER Code of Practice

First proposition based on this new design will come during next few weeks

CV aspects

EN/CV provided a first pre-design of the ventilation systems of the various sectors composing the installation This will be fed into RP/SEE

calculations for the total release into atmosphere (expected ~1 uSv/y)

Lacking a complete risks assessment (see later), conservative assumptions have been used to start design of the ventilation system

RP and safety aspects

RP aspects are well under control, and no major showstopper is to be foreseen Preparation of a summary document note

foreseen for the next few weeks Sky shine effect to be followed

PPS and risks assessment A small working group will be created (S. Hutchins

will lead it) to prepare by end of the year a risks assessment table

Document to be prepared by end of the year

On-going and critical

Target (pre)design is on-going – preliminary results at the next SBWG meeting (+ shielding thermo mechanical analysis)

Possibilities to avoid emptying the He-vessel under consideration online filtering

Horns design discussions still pending (critical for the powering part, for which people are ready contributing in the design)

ISR evaporator experience will be addressed during next SBWG meeting
