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.

We haven't dealt with these issues at VC Summer, but my personal opinion is that all 3 scenarios below would be classified as RxM, though which level would depend on the details of the calc and its impacts on plant operations.

If document was removed from use at least a year before implementation of the industry standard RM PI, it would not affect the PI. The industry standard RM PI guidance removes deductions from the current PI one year after an issue has been resolved.
If the document had been in use, was removed from use, then the error discovered, would you grade it in RM space? Yes (See response to question 2 above).

Do you directly use the PWR guideline or has it been proceduralized?

Adina, We haven't really dealt with this type of scenario. The PWROG RM PI document, step 5.1.4 states that "Historical issues (i.e. greater than 12 months since occurrence) with no recent plant impact can be evaluated for possible exclusion from the PI." Based on that recommendation, if the error had a reactivity impact and was older than 12 months I would include it.. If it had no impact I would exclude it, especially if it was removed from use. The sites Reactivity management Committee could evaluate the older than 12 month items for exclusion.

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.

Consolidated response from R.E. Ginna Reactor Engineering and Core Design:
Does your site have any guidance on how you would grade a legacy issue (NO), such as: Would you grade it in RM space if it is a calculation that is still in effect? (YES) If the document is beyond a certain age, would that change the grading? (NO) If the document had been in use, was removed from use, then the error discovered, would you grade it in RM space? (There was some discussion here. Unless there was a common cause error that propagated to current cycle, it would either be considered a level 6 [trending] or not be considered)

Does your site have any guidance on how you would grade a legacy issue, such as: NO, Probably a good topic for the next RMTT
Would you grade it in RM space if it is a calculation that is still in effect? If the document is still in effect, then YES
If the document is beyond a certain age, would that change the grading? If the document is still in effect then, I would apply RM guidelines regardless of age.
If the document had been in use, was removed from use, then the error discovered, would you grade it in RM space? By the "book" if it affected the previous 12 months, then it would impact the index for the affected months. I tink some judgement needs to be applied if the calc is no longer in effect. What was the nature/impact of the error? Was it corrected? Could it happen again? Again probably a topic for RMTT and your RMOB. I do think that penalizing yourself for an old issue is pointless, I'm just not sure how far back I would go.
