DCPP response: 1. What core loading pattern do you use? Modified crescent
2. Do you use software/equipment to physically measure the gaps between assemblies? No software or special equipment is used to measure gaps. We perform a visual verification to the vendor guidelines after reload is completed and if there are any anomalous indications, the video is reviewed by additional personnel to determine acceptability or if corrective action is warranted.
3. If so, what is the software/equipment? N/A
Later,

All,
At Kewaunee, we're considering a change from the standard bridge pattern of core on-load to a modified crescent. I have the following questions for the industry:
1. What core loading pattern do you use?
2. Do you use software/equipment to physically measure the gaps between assemblies?
3. If so, what is the software/equipment?
Thank you in advance for any information you can offer.
