North Anna uses HIS-20 and does not require a secondary identification method 
to return electronic dosimetry.

A worker could return another worker's ED by accident but would not know unless 
they caught it on the return screen or attempted to sign out another ED 
immediately after returning their ED.

This has happened occasionally when a co-worker accidently picks up the wrong 
ED at the SOP and caught the mistake at the issue/return station.

Subject: Powernet: Worker ID at RWP log out

When workers at your utility sign out of an RWP does your station use a 
secondary means of identifying the worker.  Currently BFN only uses the ED in 
the workers possession at sign out to identify the worker.  The question that 
arose was how do we know a worker signed out with the same ED they signed in 
with.

Examples of secondary identification methods could be scanning a TLD. manually 
entering a plant ID or some other method.

If you are using a means of secondary identification at the RWP exit, what 
method and software are you using?

BFN currently uses HIS-20.
