Status of the AFC design A reminder of What has
been done so far A full design Safety review
of the Absorber and it hydrogen containment
system Absorber details Primary Secondary
windows and their attachment design Coil and
coil support tube details Cold Mass support and
arrangement Support legs Module to module
system (bellow connection) Cryocooler type
specification Assembly and testing procedures

What could have been done but best be done
when feed back from the Hydrogen system and
Absorber RD is available Detail thermal
insulation / isolation at the HT leads Power
cables supply and vent pipes etc Absorber
support details Absorber heater and heating
control details Anchoring and railing details
on module supports Cold tapping details at the
first and second stages of the cryocooler Cool
down requirement for the absorbers CI
arrangement and cable routing

What is still to be done .detail definition of
the following item would be needed to allow the
manufacturing activities to commence Argon
jacket details Sizing of the vacuum
pump Cryogen cooling details Mounting details
for the vacuum pump, compressors and piping
attachments Radiation shield attachment
details Provision for the Solid Absorber

Remarks Majority of the components within the
AFC module have been looked at and where safety
is a main concern their design is almost
complete There are still a lot of minor details
that need to be addressed. We could have got them
over and done with, but they are best left to be
done later once the global design of the Cooling
Channel is frozen to avoid re-iteration of work.
These are, for instance Absorber mounting
details once we establish the real heat
leak Cryogenic piping sizing once we the
Absorber heat performance is known Cooling
arrangement attaching to the cryocoolers And of
course there are certain areas that are best done
once the RD results are available However, if a
rapid response is needed to get us in a position
where we need to start manufacturing immediately
we believe the existing information is sufficient
to allow the manufacturer to stage produce the
module without any impact on the delivery
schedule.
