Subject: [Pwrrm] SNM from fuel leaks

Request for industry peer feedback – I have the following 3 questions:

Does your site / utility account for washout or tramp SNM that may collect throughout the plant?

If you do account for the SNM, do you estimate the amount or use a method to quantify the amount?

Do you report the loss (as inadvertent losses or otherwise) on DOE/NRC form 742 or other forms?

Entergy has had fuel leaks in the past and one fuel leak currently.

Trace amounts of Special Nuclear Material (SNM) may be present in the reactor coolant, clean-up, and/or rad waste systems due to present or past fuel failures. 

The SNM is difficult to measure in the coolant system and therefore cannot be accounted for. 

But this SNM may be quantified in rad waste prior to disposal. 

Entergy Nuclear's fleet SNM Control program does not currently address the accounting treatment of this SNM.

Thanks,

Mike
