Powernet: ALARA Shielding (Refuel Upper Guide Structure)?

[Stevie . Vaughan]

Looking to see if anyone benefits from uses shielding on their Upper Guide Structure (UGS) to perform In Core Instrumentation (ICI) work.
During our Rx Head Replacement Project we have approx. 4 Rem worth of work to perform from the UGS and are looking to see if we can reduce  exposure but not compromise safety or accrue significant cost.
The UGS is accessed from an extension ladder secured to the Refuel Bridge. (Concern is safety getting lead onto platform and dropped items into the pool)
The UGS has very High contamination levels. (Concern is creating mixed waste)
