    Do Diesel Fuel Oil Storage tanks for Emergency DGs need be built to ASME BPVC III?

    Do you have access to a copy of Section III? If it were Section VIII, it seems like the tank would be outside ASME (providing you're sure about it being atmospheric). Wracking memory cells, I'm wondering if the storage tanks experience a slight vacuum when the diesel actually starts pulling...

    3D printing

    As a follow-on to this discussion, the NRC currently has open for comments a draft reg guide on commercially dedicated components (https://www.regulations.gov/docket?D=NRC-2016-0133). Although the original poster was asking about non-safety-related items, this document would eventually apply...

    old editions ASME SEC III-NG

    Late response: 1) Have you tried ASME itself? They have this on their website: Out-Of-Print Codes and Standards Select out-of-print ASME codes and standards are available for download in PDF format from our SHOP. In addition, high-quality reproductions of out-of-print (historical) codes...

    3D printing

    Short answer: No, I've never tried, or heard of anyone trying. But, if it's not a safety-related (SR) item, why would you need to qualify the material? You can use whatever you want, including stuff from the local hardware store. It doesn't affect the nuclear side of the house. That's the...

    Class 1E cables in cable trays

    New installation in the US? Part 50 or 52? For Part 50 plants, my instinctive response is that the cable trays would need to be QA1 and that you don't run 1E and non1E cables in the same tray. The rationale for the QA1 is so the cables would continue to do their safety function in the event...

    MV cable testing in nuclear plants

    A bit of a late response. I believe that there is guidance from the NRC for testing of medium voltage cables on plants that have gone through license renewal. You might find some help at the NRC's site: http://www.nrc.gov/reactors/operating/licensing/renewal.html Patricia Lougheed A FAQ...

    Anyone Have Any Soils Experience?

    Because it's basically a "homeowner" post I wasn't about to post in a technical forum. I've been scolded too many times! She's asked my brother (a construction architect in Florida) for his advice. He may know someone. And I actually worked with a soils expert here in Illinois ... but it's...

    Anyone Have Any Soils Experience?

    This is totally outside my area of expertise. My daughter lives in Tampa about 20 miles from the place where the sinkhole that just swallowed that guy in his bedroom. She called the other evening asking if there was any way to tell if a sinkhole was developing before it actually did. I have...

    circulating pump

    Valentz Is this an actual work related problem? I am asking this for two reasons: 1) You stated that you found "on the Internet" what a circulating pump was used for. And 2) Your questions are very elementary. This makes me think you are either not an engineer or this is a school-related...

    Definition of pressure vessel according to ASME

    I agree with JStephen. It's excluded under the ASME VIII definition of Pressure Vessel. Specifically U-1(c)(2) states: Based on the Committee's consideration, the following classes of vessels are not included in the scope of this Division; however, any pressure vessel which meets all the...
