We just had this discussion at the last meeting looking at an overpower condition that occurred many years ago at Byron and Braidwood.  The consensus of the BWROG on this issue was that if it currently is affecting operation, then it falls under the RM PI.  If it is something historical that is no longer impacting the site, then it would not fall into the RM PI space.  The age of the issue doesn’t matter, if it is still impacting operation.

Subject: [Pwrrm] Reactivity Management Grading

 

Good Afternoon all,

 

We recently had a discussion on site about how to grade a reactivity management legacy issue in a calculation. 

 

Does your site have any guidance on how you would grade a legacy issue, such as:

Would you grade it in RM space if it is a calculation that is still in effect? 

If the document is beyond a certain age, would that change the grading?

If the document had been in use, was removed from use, then the error discovered, would you grade it in RM space? 

 

Thank you in advance.
