02 Nuclear Infrastructure
Qualification is part of the material.
JOTAIN can review conventional or non-safety material and processed-component enquiries only when the purchaser identifies the code boundary, approved material specification, quality plan, surveillance points, and required records.
Component catalogue / 01
Where we can enter the supply route
Start with the component, then define the material condition, processing boundary, inspection plan, and documentary release.
Conventional anchor material
Bar and threaded material for non-safety infrastructure where the purchaser approves the source and route.
- Approved raw bar
- Heat-treated condition when specified
- Drawing-defined preparation
Approved fastener or bar stock
Material considered only against the purchaser's exact procurement specification.
- Material identification
- Controlled processing
- Order-specific acceptance
Auxiliary-equipment blanks
Shaft, pin, or machined blanks for conventional equipment scope when classification permits.
- Bar or forging route
- Machining allowance
- Specified inspection
Traceability and inspection dossier
Order records arranged around the approved quality and inspection plan.
- Heat identity
- Test records
- Release documentation
Engineering conditions / 02
Define the service before the grade
The candidate route becomes meaningful only after load, environment, geometry, interfaces, and acceptance criteria are controlled.
Classification
The purchaser must define whether the item is conventional, safety-related, or important to nuclear safety.
- Safety function
- Code class and boundary
- Approved-supplier requirement
Quality plan
Processes and hold points follow the contractual quality plan.
- Special-process approval
- Source surveillance
- Nonconformance control
Records
Acceptance depends on controlled identity and documentation.
- Chain of custody
- Document retention
- Purchaser and licensee review
Material route / 03
Material selection boundary
No default grade recommendation applies. The purchaser's approved material list, code class, drawing, procurement specification, and quality plan control.
Processing sequence / 04
A route that can be inspected
- 01Qualification review
- 02Approved material sourcing
- 03Controlled processing route
- 04Hold-point inspection
- 05Record compilation
- 06Purchaser release
Verification / 05
Evidence travels with the route
Define test location, acceptance criteria, inspection timing, marking, and release records before production.
Identity control
- Heat and product identification
- Chain of custody
- Approved source evidence
Contractual inspection
- Quality-plan hold points
- Specified testing and NDT
- Nonconformance disposition
Record package
- Material records
- Processing and inspection records
- Purchaser-defined retention and release
Standards context / 06
Reference the rule set—do not imply approval
The purchaser's approved drawing, project specification, inspection and test plan, and contractual standard editions control the order.
ISO 19443
Nuclear supply-chain quality-management context for products and services important to nuclear safety.
Open reference ↗ASME nuclear code-book framework
Code, NQA-1, material, examination, and authorization context when contractually applicable.
Open reference ↗Technical enquiry / 07
Send an enquiry engineering can review.
Include these inputs to reduce assumptions, shorten technical clarification, and keep the proposed route inside the purchaser's design boundary.
