[Global] Hot Spot Removal

[Bryce Beattie [Bruce B Plant Manager]]

Greetings,

At the Bruce we track hotspots in a dedicated database and monitor them routinely via our routine survey program (with long reach survey meters and robotics).  Each hot spot is identified in the station with an approved tag.   They are prioritized for shielding/removal based on magnitude and probability of exposure.   Where possible we put these hot spots on the station plan for removal but that is not always possible or practical.  Flushing is always the first attempt in removal then physical pipe/component replacement.  Often, we utilize our in-house 3D printed tungsten shielding for these as it offers the greatest shielding efficiency by reducing the weight to an absolute minimum.  Recently we have purchased an elaborate ultrasonics kit for hot spot removal but are currently stalled due to engineering concerns.   If anyone out there has any advice on that hurdle, we would love to hear from you.  Feel free to contact me directly for further discussion.

Hello all!!!



I have been given a request to assess how other plants in the industry resolves issues with hot spots that are found while performing routine surveys.  What methods do you employ?  At Salem we will attempt flushing if that is feasible or shield the hot spots if there will be significant work being performed in that area.  Do you have a hot spot tracker that you use for them?  Do you mark them in any special way to allow the workers in the area to readily identify the hot spot?



Your response would be greatly appreciated.



Thank you for your time.
