Subject: [powernet] Quick Benchmark on ED only entries into RCA

I'm performing a quick benchmark to determine efficiencies gained and/or cost 
savings by allowing entry into the RCA with only an electronic dosimeter.
1.  Does your utility allow entry into the RCA with only an electronic 
dosimeter under certain conditions or for certain types of workers (i.e., no 
TLD, OSLD)? Visitors enter our RCA with only an ED
2.  If so, what are the plant conditions/limitations and or types of workers 
(i.e., vendors, visitors)?
No entry into high rad, locked high rad., very high rad., contaminated areas, 
or airborne areas.  Entry is only allowed for brief inspections and tours 
through radiation areas.  Visitors are not allowed to perform work or handle 
radioactive material.  Visitors are limited to 2 mrem per entry and 10 mrem 
annually.  ED setpoints are 2 mrem dose and 20 mrem/h dose rate.  (This is 
controlled by means of a visitor specific RWP.)  Visitors must be briefed for 
the entry, and the escort is ultimately responsible for the individual's 
radiological and industrial safety.
3.  Is the entry recorded into the normal access control system or other means 
such as manual entry?
Typically visitors are logged into Sentinel using a visitor kiosk, allowing for 
normal electronic logging.  On some occasions visitors are signed in on paper 
and an ED is setup manually for that entry.
4.  What are the pros and cons that your utility has seen with this practice?
Nothing noteworthy.
5.  What, if any, regulator or assessor feedback have you received on this 
practice?
None that I am aware of.
Any additional information you may have on this subject is welcome.  Thank you.
