Welding

: 410 ICs welded, ≈ 2 sec-eq: No welding this week to build a buffer of ICs ready to be welded (Announced @ last LSC)Holes in 56 and 67 will be done next weekWork at a rate of 35-40 IC/week to start next week in 78 (About 70 ICs will be available on Monday), to sustain up to end 2013Will be integrated in the overall rebaseliningSlide14

Reclosure

of interconnections : On-going in 67 (priority) and 56 (> 1 sec eq), 120 ICs are reclosed in 56 and 100 in 67Priority is on S67Global rate to increase and reach baseline value with the reinforcement of part of the DN200 teamSlide16

SMACC Progress report by sector

Main activities are on non-conformities

Overheated cable

resoldered, now to be shunted and reinsulatedUninstall shunts to remove the DFBAK shuffling moduleSimilar repair (Sandwich) to be applied in other ICs Courtesy M Duret, N Dalexandro, P Voisin, R PrincipeQQBI.27R8

QBQI.18R8Slide18

SMACC Progress report by sector

All non-problematic ICs are shunted, insulated and

rewelded

Main activities are the leak test of M lines, the reclosure and the final leak testsThis sector should be the first to be ready for pressure testPlanned to be completely reclosed for end of NovemberSlide19

SMACC Progress report by sector

All non-problematic ICs are shunted

Main activities are the installation of the electrical insulation and the

rewelding of M lines (to start next week)Slide20

Opening

is ahead of schedule Shunting is almost back on scheduleCritical activity is the insulation (Progress curve soon to be included)Welding and M leak test are limited by release rate, confident that nominal rate can be achieved, margin has been eaten upReclosure: Not yet nominal rate, to be increased

Final leak test on-

going for almost 1 sec eqSlide21

Conclusions

DN 200 installation is completed

Repair the overheated cable in 56 completed as planned

Delays are stabilisedMargin has been eaten up for some activities (M welding, M leak test)Solution is under implementation for the components of the quadrupole diodesIssues:Consolidate the splices production rates and increase the rate of installation of the insulation systems keeping qualityImpact of repair of DFBA bellows (SIT & Vac subsectors)So far, not so bad …Slide32
