The EWI Nuclear Fabrication Center just completed the last high productivity technology demonstration.  The first demonstration was completed with AREVA to demonstrate a new machining technology, the second with Babcock & Wilcox to demonstrate an integrated laser/robotic technology for welding tube sheets and the final with PCC to demonstrate and compare Tandem GMAW & Laser Hybrid welding with the industry standard submerged arc welding technology.  The demographics for the demonstration attendees tell a compelling story.  While the target audience for each technology was the nuclear industry, those that attended covered a wide breadth of fabrication industries.   We averaged approximately 50% of the attendees from non-nuclear industries.  This strongly supports the notion that technology transcends industry sectors.  The feedback and follow-on work resulting from each demonstration suggests that one of the primary factors holding back US manufacturers is knowledge about the deployability of technologies.


Thanks to all the NFC members and the Department of Energy for helping make this program a huge success.  Don’t forget to take our fabrication survey (


EWI, PCC, the EWI Nuclear Fabrication Center, and the DOE Office of Nuclear Energy are hosting a high productivity welding demonstration on April 19th.  The demonstration is designed to provide fabricators the necessary information and first hand exposure to high productivity welding processes like Laser Hybrid Gas Metal Arc Welding (GMAW) and GMAW Tandem.  The two processes will be baselined against the industry standard of Submerged Arc Welding (SAW).  Each of the three welding processes will be demonstrated on ~1-1/2-in thick HY100 plate.  The joints are going to be 5 feet long and the restraint will be comparable for each process.  The processes will be evaluate in terms of cost to implement, distortion, inspectability and typical resultant properties from each process.

Please join us for the exciting demonstration by registering in advance, space is limited and we don’t want you to miss out.

This month is National Welder Month and NEI is helping get the message out.  They just posted some data from a study that EWI and NFC helped generate on their Facebook page.

2012 NFC Spring Meeting

Using the magic of google, I was able to create a map that is easier to update and embed more information.  So the map located under my previous post “Where are the Utica Shale Wells being drilled” is being abondoned.  The link below will be updated on a regular basis and includes both Utica and Marcellus in activities in Ohio.  The data still comes from ODNR’s website.

Utica Shale Maps

While conducting some research on the Barnett and Bakken Shale production rates, Google led me down an unintended path.  The search engine took me to a presentation by the Ohio Department of Natural Resources given to the US Energy Association on November 8, 2011.  The presentation showed a map of the maturity of the Shale in Ohio. 

I decided it might be interesting to overlay this map onto the one I maintain showing Ohio’s Utica well permit locations and see what it looked like.  For fun, I took this exercise one step further and over overlaid the formation thickness on to the well locations plot.  If someone was able to map out all the gas pipelines in Ohio and percent organic carbons in the Shale, the combination of the four maps would give you a pretty good idea where the gas companies are going to focus their activities in the near future–at least I would think so.  NGL rich + substantial thickness for production + high organic content + proximity to an existing pipeline = probable areas for Exploration.

I am not a geologist so this is just speculation, but that’s what happens when you cross a stray Google search with an my personality.

Neutron Cross Sections

Nate Ames —  January 3, 2012 — Leave a comment

When talking about nuclear materials, a phrase that often gets spoken is Neutron Cross Section.  In a generic sense, the neutron cross section of an element is the respective probability of a neutron to hit the element (and presumably to cause damage to the element).  Different elements have different neutron cross sections, attached is a spreadsheet and graph of the approximate neutron cross sections of different elements.

Every few weeks the Ohio Department of Natural Resources publishes a spreadsheet that details the Utica permits issued in Ohio and the status of the drilling for each permit.  These are available for download at  To help Ohioans visualize the Utica Shale activity in Ohio, EWI has created an interactive Google map (  We are working to keep this map up to date with the permit locations as well as the status.  At present the map only includes Utica sites, but it is important to note that there are also Marcellus Shale wells and conventional oil and gas wells being drilled on a daily basis all around Ohio.  The picture below is of a conventional gas well being drill less than 2 miles from a Utica well in Guernsey County.

NFC Fall Meeting

Nate Ames —  November 8, 2011 — Leave a comment

The NFC held our fall meeting in conjunction with ATI’s Corrosion Solutions Conference 2011 in Lake Louise, Alberta, Canada last week. For those of you that were unable to attend, I wanted to pass along a summary of events. This was ATI’s 8th Corrosion Solutions Conference and the first time that a Nuclear Material Summit was added to the conference. More information about the conference can be found at

The nuclear portion of the conference began on Wednesday afternoon and continued throughout the day on Thursday and was well attended on both days. Of the 16 papers presented during the nuclear sessions, 10 of the papers were given either by NFC members or on NFC specific projects. In general, I think the nuclear portion of the conference both showcased our NFC members and provided them ample opportunity to network with others in the oil, gas, chemical processing, and specialty manufacturing industries.
