TSU CONS Reliability Meeting - 6

Present: M. Blaszkiewicz, L. Felsberger, J. Uythoven, N. Voumard, P. Van Trapen

Minutes

FMECA

Started, very much still ongoing, it is a lengthy process. They will be ready in one or two weeks. Short circuits filled in, then the other modes. 

NV: Rotary switch - cross check between two TSUs. They are read only at start up: not continuously read. They can be compared to a database and validate before arming the TSU. During the operation, even if they change, they are not relevant for reliability.  

PVT: the study results are not necessary before the Design Office's routing. It will take 3-4 weeks, but it doesn’t need to be finalised. It would be good to have the analysis before the holidays.

Design review

Not many changes overall - some in the BIS interface reported by the MPE.

Project timeline

Prototype by the end of the year. Changes can still be done afterwards. Validation next year. So the study should be concluded in the beginning of September. The files submitted to the Design Office already now. 

Other

Establishing end-effect with a simulation model is possible for smaller subsets of components. If there are parts wherenot it is necessary, we will proceed. 

Actions

  1. Re-run the failure rate prediction for the latest project changes from Gitlab. (Changes to be pushed to the repository later today).
  2. Less urgent: look into functional specifications as well as the power distribution analysis.
