NUCLEARIMS BY HELIO ATLAS
Nuclear requirements.
Everyday discipline.
Put nuclear requirements into practice. Give your teams clear instructions, defined responsibilities and a traceable record of the work.
The nuclear solution built on the Helio Atlas platform.
PURPOSE-BUILT FOR NUCLEAR WORK
Rigour, where
the work happens.
From early project decisions to ongoing operations, keep requirements and evidence close to the people doing the work.
Establish the foundation.
Requirements, responsibilities and project governance.
Maintain operational discipline.
Controlled instructions and records of completed work.
Preserve the design basis.
Traceability through engineering and technology delivery.
REGULATORY FOUNDATIONS
Built for your jurisdiction.

NUCLEARIMS IN PRACTICE
Follow the basis
behind the work.
From a source clause to a completed record, preserve the context needed to perform, review and explain the work.
FACILITY LIFECYCLE
Across the facility lifecycle.
Choose a stage to explore the work, controls and evidence that need attention.

Site evaluation
Establish a defensible starting point.
Organize site investigations, environmental studies and the requirement basis behind early project decisions.
- Applicable requirements and source references
- Study responsibilities and review criteria
- Evaluation records and decision evidence

Licensing & preparation
Build the basis for the next authorization.
Coordinate licence obligations, commitments and supporting information while preparing the organization and site for the next stage.
- Submission inputs and accountable owners
- Commitments, interfaces and readiness reviews
- Supporting records and approval history

Design
Carry requirements into the design.
Keep design inputs, engineering interfaces and review decisions connected to the requirements and work they support.
- Design requirements and acceptance criteria
- Engineering responsibilities and change control
- Review records and design-basis traceability

Construction
Control the work as the project takes shape.
Define construction activities, contractor interfaces and quality records so completed work can be reviewed against its requirements.
- Construction work packages and hold points
- Supplier and contractor responsibilities
- Inspection records and non-conformance follow-up

Commissioning
Demonstrate readiness through verified results.
Organize test activities, acceptance criteria and turnover information to support a controlled transition into operation.
- Commissioning plans and test instructions
- Acceptance criteria and readiness reviews
- Test evidence, deficiencies and turnover records

Operations
Maintain discipline throughout facility life.
Keep operating instructions, maintenance responsibilities and assurance activities current, including long-term operation and refurbishment.
- Controlled procedures and assigned roles
- Maintenance, modifications and periodic reviews
- Operating records, findings and corrective actions

Decommissioning
Manage the transition to a new end state.
Coordinate changing obligations, dismantling activities and waste responsibilities while preserving the records needed to demonstrate completion.
- Decommissioning work and hazard controls
- Waste responsibilities and contractor interfaces
- Characterization, clearance and completion evidence

Long-term stewardship
Preserve knowledge beyond the project.
Maintain the obligations, monitoring activities and institutional knowledge needed for long-term care of the site and its records.
- Monitoring duties and continuing commitments
- Record retention and knowledge transfer
- Environmental results and stewardship reviews
