NUPIC Audit Preparation for Inspection Companies
A NUPIC audit runs in 6 stages, beginning with reach the eligibility threshold — at least five customers who are nrc.. NUPIC — a committee of NRC licensees and international nuclear plant operators, self-governing, with audits performed by lead auditors and team members drawn from the member utilities tests the system by sampling finished work backwards to the records behind it, so preparation means reconciling records to jobs.
NUPIC is not a regulator and issues no certificate. It is a cost-sharing mechanism: rather than every utility auditing the same NDT vendor separately to 10 CFR 50 Appendix B, member utilities run one joint audit, and the resulting report is shared with the membership so each licensee can use it to place the supplier on its own Approved Suppliers List. NUPIC distinguishes a full audit, which examines compliance with 10 CFR 50 Appendix B, from a commercial grade survey, which assesses the critical characteristics of the components supplied. It publishes the checklists used and an annual audit and survey schedule, and its programme documents are numbered — NUPIC Document 6 describes the joint audit programme and Document 11 the implementation guidelines. What separates firms that clear an audit from firms that collect findings is not the quality of the documentation but whether it describes what actually happens.

| Stage | What happens | What it tests |
|---|---|---|
| Stage 1 | Reach the eligibility threshold — at least five customers who are NRC licensees or international nuclear plant operators — and. | Where the paperwork is tested against itself |
| Stage 2 | NUPIC publishes the annual audit schedule and survey schedule; the sponsoring utility facility takes responsibility for arranging the audit and. | Where the paperwork is tested against practice |
| Stage 3 | Submit the quality assurance manual in advance, optionally posting it on the NUPIC site so member utilities can review it. | Where the paperwork is tested against practice |
| Stage 4 | Host the audit — typically about five days, conducted between 8am and 5pm Monday to Friday, longer or shorter with. | Where the paperwork is tested against practice |
| Stage 5 | Respond to findings with corrective action; the audit team closes them and issues the joint audit report into the NUPIC. | Where the paperwork is tested against practice |
| Stage 6 | Each member utility independently accepts the report and places the supplier on its own Approved Suppliers List for a defined. | Where the paperwork is tested against practice |
| Renewal | Most vendors sit on NUPIC's standard 33-month audit schedule; fuel suppliers are on a 36-month cycle. Continued eligibility depends on retaining member sponsorship — an audit is arranged and paid for by the sponsoring utility facility, so a supplier that loses sponsors falls off the joint schedule and reverts to individual utility audits. | Diarised from the certificate date, not the last audit |
How long does NUPIC audit preparation take?
Document work — the written practice, procedures and quality manual — takes weeks. What cannot be compressed is documented experience and records history: on-the-job hours accrue in real time, and calibration and certification history cannot be back-filled. Firms that start when the audit is scheduled rather than announced clear it without findings.
What does NUPIC — a committee of NRC licensees and international nuclear plant operators, self-governing, with audits performed by lead auditors and team members drawn from the member utilities look at first?
Records, not manuals. A manual states intent; records show practice. The usual opening move is to take a completed job and trace it back to the technician's certification, the instrument's calibration, the approved procedure and the report — and see whether all four reconcile.
What are the most common NUPIC findings?
Written practice and certification packages inconsistent — certificates issued for methods or techniques the training and experience records do not support, 10 CFR Part 21 procedure absent or not recognising that inspection, testing and consulting services are themselves basic components under the Part 21 definition, Commercial grade dedication performed without identifying critical characteristics or without the acceptance methods required, so the item never becomes a basic component, Calibration laboratory relied on without an evaluation, or with an ISO/IEC 17025 scope that does not actually cover the parameter and range being used. Almost all of them are evidence problems rather than capability problems: the work was done correctly and the proof was not kept, or was kept somewhere the firm could not retrieve during the audit.
Can a consultant attend the NUPIC audit?
Yes, and it changes the outcome. Someone who has sat through the same audit at other firms answers in the auditor's own terms, produces the right record without a search, and stops a clarification turning into a finding. The firm still owns every answer — the consultant does not speak for it.
What happens after a NUPIC finding?
A corrective action with a deadline, and evidence of closure at the next audit. Repeat findings are treated far more seriously than first ones, because they show the corrective-action system itself is not working.
Does NUPIC require a pre-audit or gap assessment?
Not as a requirement, but the arithmetic favours it: a gap assessment finds the same evidence problems the auditor would, without the finding attached, and while there is still time to fix them. Firms entering their first NUPIC audit blind typically collect findings that a sampling exercise would have caught.
What the auditor asks to see
- Quality assurance manual, which NUPIC suppliers may submit for posting on the NUPIC website at no charge so member utilities can download it
- NDE written practice and the personnel certification packages behind it — training, experience, written, practical and where applicable specific examinations, plus vision records
- NDE procedures and, where inservice inspection is in scope, evidence of ASME Section XI Appendix VII qualification and Appendix VIII performance demonstration
- Completed NUPIC Audit Checklist, NUPIC Survey Checklist or Calibration Checklist as applicable to the scope
- Commercial grade dedication and critical characteristics documentation where the supplier is being surveyed rather than audited
- 10 CFR Part 21 procedure covering evaluation of deviations and reporting of defects and failures to comply
- Calibration records with traceability, and for calibration and testing services any ISO/IEC 17025 accreditation being relied on under the NUPIC ILAC process and NEI 14-05A
- Internal audit programme records and the corrective action programme
- Approved sub-tier supplier list and evidence of sub-tier evaluation and flowdown
Findings to close before the audit
- Written practice and certification packages inconsistent — certificates issued for methods or techniques the training and experience records do not support
- 10 CFR Part 21 procedure absent or not recognising that inspection, testing and consulting services are themselves basic components under the Part 21 definition
- Commercial grade dedication performed without identifying critical characteristics or without the acceptance methods required, so the item never becomes a basic component
- Calibration laboratory relied on without an evaluation, or with an ISO/IEC 17025 scope that does not actually cover the parameter and range being used
- Sub-tier NDT contractors used on safety-related scopes without evaluation, flowdown of Appendix B and Part 21, or surveillance
- Corrective action programme closing conditions adverse to quality without cause determination or extent-of-condition review
- Internal audits not covering all programme elements within the stated frequency, or performed by personnel with responsibility in the audited area
- Records retention and legibility failures — inspection records that do not identify the examiner, the observation, the acceptability, and the disposition of deficiencies
