Glenn, At Ginna/NMP/Calvert Cliffs we use the same dosimeters with the case you are describing.
The first thing I want to say is for everyone out there - do not go and change out your cases! Your accreditation with Landauer is specific to the OSL in their specific case. If you put the OSL in another case you may void the accreditation. At our site, a similar issue has been turned into a Condition Report for FME concerns and I know the same issue exists at Calvert and Nine Mile. While Landauer did redesign the case it has not turned out to be sufficient. Our corrective actions (in progress) are to determine what the cost would be to get an accreditation using the clam-shell cases. Depending on the cost we will pursue this course and continue to provide Landauer with complaints. Perhaps if enough of us contact Landauer they will address this issue. Bryan S. Pell R.E.

Sent: Wednesday, February 15, 2012 3:11 PM To: [email protected] Subject: Powernet: OSL dosimeters Columbia is inquiring: For plants that are using OSL dosimeters, specifically InLight Dosimeters, have you experienced a failure of the fastener (plastic thumbtack-like piece) by either breaking in two or falling out of place? We have had several occurrences of fastener breakage since we began using InLight Dosimeters in September 2011. The vendor has redesigned the fasteners and has used them with the January 2012 batch of dosimeters. However we have had four instances of fastener failure with this new batch of dosimeters. Just trying to determine if it is a continuing design flaw or an assembly problem. Your InLight insight is appreciated. Glenn W.
