Reactor Recirc. Pumps




The Detroit Edison Fermi 2 Plant will be performing the removal of the 
rotating assemblies for our Reactor Recirculation Pumps.  I know that this has 
been performed at other utilities in the past, and I am requesting some 
information from the RADSAFE community pertaining to the following questions: 
 
1. What was the dose rates on the shaft/impeller? 
2. What was the total dose accumulated for the job? 
3. How did you shield the rotating assembly after removal? 
4. Did you ship the assembly or store it on site? 
5. If you did ship it, how did you partake in deconing it? 
 
And finally, were there any Lessons Learned that would help in the planning of 
this job in the future.   
 
I would like to thank anyone in advance who responds to this.  You can reply 
to me personally at woodsr@detroitedison.com or to RADSAFE.  Thanks again.
