Establish the real constraint
Configuration, ageing, obsolescence, evidence quality and blocked owner decision.
Mandate 02 / Modernize & Extend
Nuclear integrity, modernization and lifecycle decisions.
For ageing assets, open inspection findings, legacy design bases and repair or modification choices. NIQS converts the available evidence into a checked decision basis and implementable closure route.
Direct answer
NIQS supports owner teams that have calculations, inspection results or supplier packages but still lack a defensible decision. The mandate defines the acceptance basis, reconciles configuration and uncertainty, compares lifecycle options and connects the selected route to implementation and close-out.
Call NIQS when
The package exists. The owner decision is still open.
- An inspection finding or ageing concern needs a continued-operation or outage decision.
- A stress, fatigue, fracture, dynamic or multiphysics calculation needs an accountable decision context.
- A repair or modification approaches an outage with open design, qualification or interface questions.
- Legacy calculations, loads, transients, materials or configuration cannot be reconstructed cleanly.
- A supplier package is complete as a deliverable but does not yet support owner acceptance.
Mandate shape
Modernization Decision Package, fixed assessment or technical lead through modification close-out.
Technical scope
A traceable basis for a defined mechanical decision.
The decision, source hierarchy and acceptance basis are defined before analysis begins. Material conclusions remain linked to identified inputs or explicit assumptions.
Decision and code basisAssessment boundary, applicable requirements, load cases, acceptance criteria and source hierarchy.
ConfigurationAs-designed and as-built reconciliation, materials, supports, interfaces, ageing and modifications.
AssessmentApply the stress, fatigue, fracture, dynamic, hydraulic or multiphysics methods required by the decision.
OptionsCompare continued operation, monitoring, repair, redesign, replacement and their dependencies.
Implementation basisRequirements for design, calculation, procurement, inspection, testing and supplier evidence.
Close-outControl hold points, reviewer interfaces, as-built evidence, acceptance and residual actions.
Controlled work products
Engineering that supports acceptance, action and close-out.
- Assessment planScope, requirements, methods, roles, hold points and checking basis.
- Input and assumption registerTraceable configuration, loads, transients, materials and uncertainties.
- Checked assessmentMethods, results, margins, limitations and acceptance disposition.
- Option comparisonTechnical risk, lifecycle implications, interfaces and verification needs.
- Technical specificationRequirements for repair, modification, replacement, inspection or testing.
- Verification and closure dossierSupplier findings, as-built evidence, acceptance and residual actions.
Smallest sensible start
Modernization Decision Package.
A focused comparison of repair, replacement, redesign, monitoring and lifecycle options before committing to the implementation programme.
Compare defensible paths
Technical risk, lifecycle implications, qualification needs and implementation barriers.
Carry the decision into closure
Specification, procurement support, engineering, acceptance and as-built close-out.
Role boundary
Formal licence-holder, design-authority, accredited inspection and regulatory responsibilities remain with the relevant organisations. Checking independence is defined by the mandate.
Confidential first contact
Start with one asset and the decision that cannot yet be defended.
