Re: Cobalt Impurities Resources

["Gerry W. Kindred" <gwkindred@centerior.com>]

Use the following resources:
---> ASME Boiler & Pressure Vessel Code, Materials - Part B
---> Cobalt Reduction Guidelines (EPRI)
There are some others that I have used in the past; however,
the title escape me for the moment.
Also, if you want empirical data, if available, get a copy of the 
CMTR - Certified Material Test Report for the material that the
cable was fabricated from.  
For my information, what is the equation you are using to 
determine the activation?  I'm also curious of what neutron flux
you are using along with in-core residence estiamtes.  If you
don't want to broadcast teh info just reply to me personnally.  
If I can help you any further, let me know.  Say hey to Bob Hite
for me.  Bob and I served on an industry committee together
a few years back.
