Nuclear inspection and test plan (ITP) template

The ITP sets out each manufacturing operation with its inspection, who performs it and whether work may continue without it. Once signed, it becomes the record that everything was inspected on time.

In one sentence

The inspection and test plan sets out the sequence of manufacturing or erection operations, the inspections and tests for each with their procedure and acceptance criterion, who takes part —manufacturer, quality assurance, licensee inspection— and which points are mandatory hold points, and once signed it serves as a record, because the inspection criterion of nuclear quality assurance requires planned inspections and hold points that cannot be passed without authorisation, as CSN guide GS-10.5 explains.

Content reviewed on 17 October 2026

Type of information: Mandatory record Inspection, testing and inspection status criteria; GS-10.5. Lifetime record for the licensee (IS-24)
Who fills it in: Manufacturer’s quality assurance Prepares it with engineering; it is accepted by the licensee, which marks its own hold and witness points
When: Before manufacturing begins Signed off operation by operation as the work proceeds
How long it is kept: Lifetime or at least 5 years IS-24 requires licensees to keep as lifetime records, for the whole life of the facility or component, those meeting any of its criteria, and to keep non-permanent records for at least five years. Suppliers apply whatever the licensee’s purchase order specifies.

What the standard requires

What UNE 73401 demands and what it leaves to your judgement

Nuclear quality assurance criteria call for an inspection programme for activities affecting quality, carried out by people other than those performing the work, with procedures, acceptance criteria and, where required, mandatory hold points beyond which work does not continue without the corresponding inspection.

They also require the inspection status of each item —pending, accepted, rejected— to be identified so that it is not used before being verified.

Inspection and test records for structures, systems and components are lifetime records under Instruction IS-24.

Example

Example: ITP for a safety-class support

Company, people and figures are fictitious: the example only shows what a properly completed record looks like.

Field	Content
Item	Support SP-114 · order PD-4471 (fictitious) · ITP revision 2
Operation 1	Material receipt: review of certificates and marking · quality assurance performs · licensee document review
Operation 2	Fit-up and tack welding: dimensional check · manufacturer performs
Operation 3	Welding to WPS-022: visual inspection · quality assurance · hold point
Operation 4	Radiography of butt welds · evaluated laboratory · licensee witnesses
Hold point	Operation 3 released by the quality assurance inspector on 12 March 2026
Operation 5	Final dimensional check and dossier review · licensee hold point · released on 19 March
Final status	Accepted · green tag and final dossier issued

At the audit

Mistakes auditors commonly flag

Operations after a hold point carried out before it is released.
Inspection signatures without a date, or all added at once at the end.
An ITP that does not match the current revision of the drawing or procedure.
Items in the workshop with no indication of their inspection status.
The licensee is not notified of its witness points in time.

In Kimobox

How this record is kept in Kimobox

1Inspection and test plans are recorded per item.
2Each item’s inspection status is documented in its file.
3Every hold point carries the signature, date and name of whoever released it.
4Inspection and test results are linked to the item and its traceability.

Frequently asked questions

What people ask us before getting started

What is a hold point?

An operation in the plan beyond which work cannot continue until the inspection has been performed and released by the designated person, from the manufacturer or the licensee.

How does it differ from a witness point?

At a witness point the person who should attend is notified, but if they do not turn up within the agreed time the work may proceed. At a hold point, it may not.

Who inspects?

People other than those who did the work being inspected, with the necessary qualification. The licensee may add its own inspections on top of the manufacturer’s plan.
