Powernet: Tracking electronic dosimeter dose to tenths?

[Eric . Goldin]

San Onofre currently tracks electronic dosimeter dose to integer mrem (a deliberate decision when we implemented the MGPI DMC-2000S dosimeters).  We understand that some plants track dose to tenths of an mrem.  Reportedly, there is an ALARA benefit for this additional precision.  I have two questions:

How many plants/fleets are tracking ED dose to tenths of a mrem?

How does such precision impact ALARA performance?  In other words, what worker behaviors change when a worker sees 4.4 mrem instead of 4, or 4.7 mrem instead of 5?

Thanks and Happy Holidays from sunny (today) California, Eric
