Power generation buyers filter fabricators on ASME code stamps and nuclear buyers on NQA-1 programme status. A capability page must state the code stamps held, the vessel and piping scope they cover, and whether the shop holds a nuclear quality programme.
Two qualifications sit in this sector and they are separated by an order of magnitude in cost. The gate here, and the equivalent in every other sector, is indexed at [manufacturing SEO by industry](/industries). ## Code stamps gate conventional work **An ASME code stamp authorises a shop to build pressure equipment to a section of the boiler and pressure vessel code**, and it is issued per stamp, per scope, and per facility after a survey. The U stamp covers pressure vessels, S covers power boilers, PP covers pressure piping, and holding one confers nothing for another. Naming the stamps held, their scope, and the authorised inspection agency gives a buyer three matchable facts where "code fabrication" gives none. **An authorised inspector must witness the work**, which means code fabrication carries a scheduling dependency outside the shop's control. Saying which agency the shop works with, and typical inspection availability, addresses a lead time question buyers ask late and worry about early. ## NQA-1 is a different order of qualification **NQA-1 is the nuclear quality assurance programme, and it requires documented control well beyond an ASME stamp.** A supplier holding it has committed to a records, training, and audit regime that is expensive to maintain and slow to obtain. That expense is why a second route exists. **Commercial grade dedication allows a qualified buyer to accept a non-nuclear part into safety-related service by verifying critical characteristics itself.** A shop that understands dedication, and can supply the documentation a dedicating entity needs, can serve nuclear work without holding NQA-1. Stating which of the two routes applies is the single most useful sentence a supplier can publish for this market, and almost none do. ## Outage schedules invert the normal urgency A generating station schedules outages years ahead and then works to the hour. Parts required during an outage arrive with a fixed date and a cost of delay measured in lost generation. **A supplier stating outage support capability, including expedite and after-hours capacity, is answering the question that decides those awards.** That statement is worth more than a general lead time, because the buyer is not comparing weeks, they are comparing whether the date can be met at all. ## What the capability page must state **A capability page must state process, materials, tolerances, capacity, certifications, and industries served**, and power generation adds four. ASME stamps with scope and authorised inspection agency. NQA-1 status, or commercial grade dedication support. Material traceability practice, including for outside services. Outage and expedite capability with a stated date commitment. Large-envelope capacity matters here for the same reason it does in [oil, gas, and energy](/industries/oil-gas-energy), and the two sectors share most of their fabrication vocabulary. The structure is in [capability page structure](/content/capability-page-structure). ## Vocabulary the sector searches in Requests use code stamp, U stamp, Section VIII Division 1, NQA-1, 10 CFR 50 Appendix B, safety related, commercial grade dedication, outage, and turbine. **Safety related is a defined term rather than a descriptive one**, and using it loosely marks a supplier as unfamiliar with the sector. ## How the qualification runs **A supplier qualification audit here is conducted against a written programme rather than a general checklist**, and for nuclear work the audit is performed by the utility or a dedicating entity with its own regulatory exposure. **The industrial buying cycle typically spans several months to more than a year**, and nuclear qualification runs longer still, which makes an incumbent position in this sector unusually durable once it is held. What that means for measuring a programme is set out at [how long manufacturing SEO takes](/manufacturing-seo/timeline). ## Common questions **Can a shop do power work without a code stamp?** Yes, for non-code components, structural work, and machining. The stamp gates pressure-retaining fabrication specifically. **Is NQA-1 worth obtaining?** Rarely for a small shop. Commercial grade dedication is the route most suppliers take into nuclear work, and supporting it well is cheaper than holding the programme. **What does an authorised inspector actually control?** Witness points during fabrication. Their availability is a real schedule input, which is why publishing the inspection agency is more useful than it looks. **Does renewable generation use the same qualification?** Partly. Solar and wind borrow the structural and traceability requirements and rarely involve code stamps, which makes them an easier entry. **How should outage capability be stated?** As a commitment with a date and a scope. General claims about responsiveness do not survive comparison against a supplier who names a delivery date. --- Source: https://manufacturingseo.ai/industries/power-generation/ Last reviewed: 2026-08-09 Author: ManufacturingSEO.ai
