Establish the credible mechanism
Evidence map, causal model, critical gaps and prioritised validation actions.
Mandate 01 / Diagnose & Recover
Nuclear root-cause analysis and reliability recovery.
For recurring failures, bad actors and mechanically open plant-performance problems. NIQS integrates the evidence, tests the mechanism, engineers the intervention and verifies the change.
Direct answer
NIQS supports nuclear owner teams when the asset symptom is visible but the controlling mechanism or corrective route remains open. The mandate produces a defensible causal basis, prioritised intervention plan and verification logic tied to the plant decision.
Call NIQS when
The same issue keeps returning, or the available evidence points in different directions.
- The same failure, leakage, alarm, degradation or maintenance demand has returned.
- A system or component underperforms despite maintenance or local corrective actions.
- Condition, inspection, operating, calculation and work-order evidence remain fragmented.
- A bad-actor campaign has data but no agreed mechanism or decision route.
- Operations, maintenance, engineering, projects and suppliers each hold part of the closure path.
Mandate shape
Fixed critical-asset diagnostic, system recovery package or accountable reliability workstream.
Engineering scope
Integrate the evidence. Resolve the mechanism. Define the intervention.
Reliability is treated as an engineered plant result. Measurements, calculations, maintenance, monitoring and modification are used only where they close the controlling mechanism and decision.
Decision framePlant function, reliability constraint, asset boundary, required decision, deadline and accountable interfaces.
Evidence integrationCondition and inspection findings, operating and failure history, work orders, modifications, calculations and supplier evidence.
Mechanism testingScreen and test mechanical, structural, hydraulic, thermal, degradation, maintenance and operating hypotheses.
QuantificationUse stress, fatigue, fracture, dynamic, hydraulic, performance or multiphysics analysis as required by the decision.
Improvement planEngineer maintenance, monitoring, operating, repair or modification actions with priorities and hold points.
VerificationCheck effectiveness against the agreed baseline and criteria, with residual controls retained.
Controlled work products
Outputs that support the next owner decision.
- Decision charterPlant function, constraint, boundary, decision, deadline and accountable roles.
- Integrated evidence registerCondition, operating, maintenance, calculation and modification evidence with gaps and uncertainties.
- Causal model and test planHypotheses, evidence for and against, discriminating tests and remaining uncertainty.
- Engineering assessmentIntegrity, dynamic, performance, fatigue, hydraulic or multiphysics basis where needed.
- Reliability improvement packagePrioritised maintenance, monitoring, operating, repair or modification actions.
- Verification recordPost-action condition against criteria, residual actions and programme learning.
Smallest sensible start
Critical Asset Diagnostic.
A bounded engagement to define the mechanism, uncertainty and next decision before committing to the full recovery programme.
Select the closure route
Compare monitoring, maintenance, repair, modification and replacement options.
Engineer and verify
Execute the assigned package against agreed hold points and acceptance criteria.
Boundary
Equipment unavailability or production effects are attributed only where causation and owner data support the link. Formal operator and regulatory roles remain unchanged.
Confidential first contact
Start with one asset, one symptom and one blocked decision.
NIQS will return a Fit / No-Fit view and the appropriate bounded next step.
