Illustrative immersion service example
110 min immersion service; 70 min cold-plate servicemodeled
| Value kind | modeled — Interpret this value according to its displayed kind, scope, source, and as-of date. |
|---|---|
| Scope | Assume the same failed accelerator assembly, on-site qualified spare, trained crew and a 180-minute restoration ceiling. For a cold-plate design assume 20 minutes diagnosis/isolation, 25 replacement and 25 checking/restoration. For immersion assume 20 diagnosis/isolation, 30 extraction/draining, 25 replacement and 35 reinstalling/checking. These are proposed task allowances, not measured repairs; the sequence follows the service boundaries described here. |

| Source | Guide calculation from expressly assumed teaching inputs. Primary reference supplies method or equipment context, not evidence that this design was built or tested. |
| Derivation | Cold-plate allowance = 20 + 25 + 25 = 70 minutes; immersion = 20 + 30 + 25 + 35 = 110 minutes. Both fit the 180-minute ceiling. Retain both candidates for the matched thermal and lifecycle-cost comparison; the shorter procedure alone does not price recovery of a distributed job. The immersion design has 70 minutes of remaining allowance. A missing qualified spare that adds 90 minutes produces 200 minutes and fails by 20. Stock the spare or change the service design. Acquire a timed demonstration and warranty confirmation before treating either allowance as an accepted restoration time. OCP qualification and service interfaces provide context; 14.5 owns the operating procedure and 13.5 its cooling acceptance handoff. |
