Re: Ag-110m Production

     Jim,
     
     In a former life as an HP at several power reactors, we had to deal 
     with this. The "O-Ring" (really big one!) that is between the reactor 
     vessel and reactor head is made of a metal alloy, one constituent of 
     which is silver. (Silver is used because it's soft.) As the o-ring 
     erodes/corrodes, silver is released into the coolant system. It's 
     activated into Ag-110m as it passes through the reactor at power.
     
     I'm not aware of any other sources, but I've been out of that part of 
     the industry for about 10 years now.

RADSAFER's - can anyone enlighten me as to how Ag-110m is produced in 
nuclear reactors?
     
Thanks -
