[Global] Radium Clearview Shield for Steam Generator Primary Manway

[Nolen, Jeffrey Lebron]

We use Clearview windows primarily on the refuel floor and in upper (Rx Head Lifts, Internals lifts, etc).  We have several small ones that can be hung as a window in a shadow shield or rolling shield.  Visibility is great if you stand close to the window.  Attenuation is appx 50%.  If you get them really cold they turn cloudy.

Has anyone used the clearview shield doors for steam generator E/C?
What kind of reduction were you able to realize?
Did the widow suffer scratches that compromised the visibility?
Did the upward folding locking door impede access as opposed to a side opening door?
Who performed your eddy current testing?
Did the door work well with your vendor’s tooling?

Would love to hear anything else regarding your experience.

Thanks!
