Absorber Change Procedure to extract AFC from PRY (TD-1189-1697)

Note times do not include fill/purge of H from the hydrogen system!

• At operation • Remove services obscuring AFC (excluding H purge) [5 days TBC]

• Remove part of handrail, mezzanine cut out & add bar to protect the AFC (when removing the middle plates) [0.5 day]

• Remove outer-upper doublers south middle-upper plate• Slide out south middle-lower plate at 11.5 degree angle• Before sliding out of lower doublers completely rotate vertically• Lift up and away• [1 day]

• Remove upper outer doublers & north middle-upper plate • Remove middle legs

• Slide out north middle-lower plate

[1 day] (for north side middle plates)

• Uncouple bellows between AFC & SSs [1 day]• Remove AFC [0.5 day]• Change Absorber [? day TBD]

Conclusion Detailed review of fit of PRY with various ‘components’ of the

MICE Hall have shaped the PRY design to significantly reduce / eliminate the chance of a clash.

The design of the PRY allows for AFC Absorber changes with the minimum of removal of the PRY, reducing time and risk.
