Constellation generically refers to the badges as DLRs - Dosimeter of Legal 
Record

At Ginna Station, very little of the TLD program could be converted to the OSL 
program. None of the equipment, methodology, etc., carried over well. We wrote 
procedures that refer specifically to the OSL to avoid confusion...this 
decision had more to do with the product - e.g., you put an OSL in the 
MicroStar reader not a TLD, etc, so there was really no need to attempt to 
change multiple references. As the references referring to the TLD came up for 
periodic review, they were deleted. Changes that affected the station were made 
immediately, changes that affected RP only were made over time.

Subject: Powernet: Quick Dosimetry Question

For plants that have switched from TLDs to OSLDs (or other primary dosimeters), 
when you made the switch, did you adopt another specific acronym such as OSLD 
or did you adopt a generic acronym, such as DLR (dosimeter, legal record) or 
PMD (primary monitoring device)?

For those who did switch, did you attempt to change all your references to TLDs 
at the same time (dozens of procedures, software, and training documents)?  Or 
did you make some changes as they became convenient?
