scaffold used for radiation sheilding and kept in place more than 90 days? How to handle the issue ?
(OP)
If a scaffolds used for radiation shielding are required to be kept inside the plant for greater than 90 daus, how to handle the issue in the plant licensing space and show we should address it as "temporary alteration"? How we address scaffold in 10CFR 50.59 Screening? UFSAR does not address scaffold"?

One other small caveat that is easy to miss...if you know on day 1 of installing the scaffold that it will be installed for greater than 90 days, you should completing the 50.59 screening immediately. It's hard to prove, but that can be fodder for a violation.

Follow the intent of the rules: If a structural component is going to be "permanently installed" - and not installed and removed temporarily as for an outage or for repairs or temporary shielding - classify it appropriately and STUDY IT officially as a permanent part of the plant.
