Configuration Equivalency - Panasonic & Polymar Clamshell Holder

["Sandy Perle" <sandyfl@earthlink.net>]

I am interested in any power plant who has used both the Panasonic 
UD874 Clamshell Holder and the Polymar (ISA) Clamshell Holder, 
Configuration 1-a (single open window) .. who has performed a 
technical equivalence.

I am particularly interested in the specific density and thickness 
(mm) found in the Polymar Lexan 121 polycarbonate holder and how that 
compares to the Panasonic Holder. Is there a difference, and if so, 
how much? If your facility switched from the Panasonic Holder, were 
you required to change the algorithm in any way, due to the observed 
differences between the two holders, or, were they deemed technically 
equivalent.

I am considering purchasing the Polymar Clamshell Holder, and am 
determining the extent of external irradiations to ANSI N13.11-1993 
NIST Beam Codes required.

Thanks for any information you can provide.
