ASME NQA-1 and Interface Control

OK, here is something I find confusing. I see conversations here about N stamping and getting NQA-1 certification. They are not the same thing, are they? Don't you get certified to NCA-3800 for N stamping? OH, my aching head! the more I look at this stuff the less I know.

Please, someone, please can we get some Cove lessons on how to gain NCA-3800 certification? I just wanna go and hide till it's time to retire.
Yeah, what you said! To my understanding, the N stamp certification we're going for (and there are various types of N stamps) encompasses compliance with NQA-1, NCA-3800, 10CFR50 and ASME Boiler and Pressure Vessel Code Section III. I think.:confused: I am just getting into this stuff myself.

Why does ASME publish two quality system standards, NQA-1 and NCA-3800?

Wouldn't life be easier if there were one standard, even if there were some things that, depending on the product, might not be applicable? Kind of like 9001 and being able to reduce the scope?

Both standards say pretty much the same thing, but there are (I think) more requirements in NQA-1 even though you don't actually get a certificate. Both are formatted totally different. ARRRRRRRRRRRRRGH.

Good luck, or as Tiny Tim would have said: God Bless us every one.

Good topic and it is confusing. There is value to having two standards. NQA-1 is a QA Program that is structure like ISO 9001 and allows implementation for any number of providers of nuclear products and services. NQA-1 is one way (actually really the only way) to meet the NRC's regulation on quality - 10 CFR 50 Appendix B. There is no certification for NQA-1.

NQA-3800 is very focused on material providers who provide parts (items) to an N stamp holders (N, plus others NPT....). The emphasis of NCA-3800 is material identification and control. With everything being held together through a test of the item often connected to an ASTM standard. There is a certification process through ASME for NCA-3800 that leads to a Quality System Certificate. Your N-stamp holder (or others) will include the NCA-3800 documentation with what they deliver to a user (utility or DOE) as evidence of their quality. This is done under their NQA-1 program, which is reviewed by ASME in their qualification process for getting the N stamp.

Kind of rambled. Hope it makes sense.

No those of us who work on NQA-1 and other quality committess are not lawyers, but we do choose our words carefully. After working with it for a while, hopefully it will become clearer.

True for training but not for most of NQA vs ISO. The best defination I herd was last year at the NUPIC meeting, ISO is outcome based process program and is not directed at the material. NQA 1 and the nuclear industry is a prescripted standard and deals with the quality of the product and not the process.
It is very difficult to revise an ISO manual to meet the NQA 1 nuclear requirements. It is easier to have two manuals.
As for the part about calibration of gauges, The tolerance that is applied to the measurement is more important then the performance of the gauge.

To add to Hemi999's comment ISO is customer centric, NQA-1 is quality and safety centric. Those mind-sets have completely different outcomes. I would not go as far as saying customer satisfaction is important to NQA-1, but you won't find a requirement to determine the customer's perception. And that is as it should be for a quality and safety standard.

I have to agree that separate manuals is a lot easier to work with. That is what I mostly see. Depends on what percentage of your business is going to be nuclear business. And there may be some NQA-1 practices that are worth incorporating.

Hello,

I still don't get it, we want to delivery safety related parts to a customer (in France), who is partner in a project in the U.S., they want to make an audit (Customer Audit, no certificate).

The customer was in our company the last time, and checked according 10 CFR 50 App. 5, and NQA-1, but mentioned we are not fullfil the requirements for safety related parts (we delivery since longer time for nuclear projects, but only for the turbine).

I'm doing a lot of research to match the requirements this time, I found a presentation mentioning, that for safety related parts NCA 3800 must be fulfilled?
So I need an QA Program that fulfill the NQA-1 and with that the 10 CFR 50 App. B, and for material the NCA-3800?

If I'm right what is the additional requirement of NCA-3800?

Thanks,

TamTom

Safety related usually is a term relating to part/material outside of the pressure boundary which is ASME III, NCA 3800. Safety related has to do with a system that is important to safe shut down in an emergency. NCA 3800 for material that is installed in a pressure boundary part or component. NCA 3800 is the requirements for material for material Manufacturers and material suppliers that supply to the utilities and component manufacturers. A review of your manual could be done to see if there is any gaps for NQA 1 and App. B would be a starting point and then possibly a onsite gap analysis of the implementation.

If you are only a material supplier, check the defintion in NCA 3800 for that, then all you need is NCA 3800 (as I said in my other that would NQA-1 light). What I am seeing is that some customers are looking for the additional confidence of an NQA-1 program because the supplier may be doing more than just supplying material such as altering the material properties, e.g., heat treatment, etc. As a provider of speciality materials my guess is that your be a Material Manufacturer and therefore the more stringent NQA-1 requirements would apply.
