| Proposed Topic for discussion at May 7 RI-ISI meetingAfter further review of the draft responses to the second set of RAI's, I propose the following asa topic for discussion at the May 7, 2007 meeting. | | Proposed Topic for discussion at May 7 RI-ISI meeting After further review of the draft responses to the second set of RAIs, I propose the following as a topic for discussion at the May 7, 2007 meeting. |
| | | In the response to RAI #1 in RAI set #2, the licensee stated, in general terms, why the proposed methodology is consistent with RG 1.178. Such generalities may not, however, be needed or sufficient. The method propose by the licensee effectively replaces the EPRI RI-ISI process with the generic categorization, supplemented by the IPE flooding analysis. |
| In the response to RAI #1 in RAI set #2, the licensee stated, in general terms, why the proposed methodology is consistent with RG 1.178. Such generalities may not, however, be needed or sufficient. The method propose by the licensee effectively replaces the EPRI RI-ISI process with the generic categorization, supplemented by the IPE flooding analysis. | | Licensee IPE flooding analysis have been reviewed against the ASME RAS-S-2000 standard (currently Addendum B has been issued). Rather than a discussion in general terms about consistency between the approved RI-ISI methodology and the proposed methods, it would be most productive to discuss the adequacy of the flooding evaluation with respect to a RI-ISI evaluation in terms of the specific supporting requirements (SRs) that characterize a licensees flooding analysis. The ASME standard includes three categories for each SR (Cat. I the lowest, Cat. III the highest) and the licensees analysis is placed into one of the three categories for each SR by a peer review group. |
| | | These SRs describe many of the characteristics of a flooding analysis relied upon in a RI-ISI evaluation For example, for discussion purposes, a rating of Cat. III for SR IF-C3 appears consistent with RI-ISI analysis requirements. Similarly, a Cat. II for SR IF-C6 and IF-C8 might be sufficient for RI-ISI analysis. |

The ASME standard includes three categories for each SR (Cat. I the lowest, Cat. III the highest) and the licensee's analysis is placed into one of the three categories foreach SR by a peer review group. | | It would be useful to discuss the specific SR results of the peer review of GG and DC Cooks IPE flooding analyses at the meeting, and how these results compare to the characteristics of an acceptable evaluation for RI-ISI programs. It may be feasible to appropriately characterize the adequacy of GG and DC Cooks flooding analyst to support the RI-ISI evaluation in terms of the categories assigned to the flooding SRs. If the ASME standard will not identify an analysis equivalent to the RI-ISI analysis (perhaps because of the grouping in IF-C4 and screening in IF-D7), additional RI-ISI specific additions to the SRs (or the sufficiency of the SRs instead of the RI-ISI analysis) could be discussed. |

Fwd: Proposed Topic for discussion at May 7 RI-ISI meeting, Code Case N-716 Please see the attached e-mail from the staff reviewer. As he has suggested in the e-mail, please be prepared to discuss the subject matter. Also, if you can bring any additional evaluations, analyses, supporting information, etc. for the meeting (better yet, if you can send it to me ahead of the meeting ), the discussion would go smoother.

Proposed Topic for discussion at May 7 RI-ISI meeting After further review of the draft responses to the second set of RAIs, I propose the following as a topic for discussion at the May 7, 2007 meeting.
In the response to RAI #1 in RAI set #2, the licensee stated, in general terms, why the proposed methodology is consistent with RG 1.178. Such generalities may not, however, be needed or sufficient. The method propose by the licensee effectively replaces the EPRI RI-ISI process with the generic categorization, supplemented by the IPE flooding analysis.
Licensee IPE flooding analysis have been reviewed against the ASME RAS-S-2000 standard (currently Addendum B has been issued). Rather than a discussion in general terms about consistency between the approved RI-ISI methodology and the proposed methods, it would be most productive to discuss the adequacy of the flooding evaluation with respect to a RI-ISI evaluation in terms of the specific supporting requirements (SRs) that characterize a licensees flooding analysis. The ASME standard includes three categories for each SR (Cat. I the lowest, Cat. III the highest) and the licensees analysis is placed into one of the three categories for each SR by a peer review group.
These SRs describe many of the characteristics of a flooding analysis relied upon in a RI-ISI evaluation For example, for discussion purposes, a rating of Cat. III for SR IF-C3 appears consistent with RI-ISI analysis requirements. Similarly, a Cat. II for SR IF-C6 and IF-C8 might be sufficient for RI-ISI analysis.
It would be useful to discuss the specific SR results of the peer review of GG and DC Cooks IPE flooding analyses at the meeting, and how these results compare to the characteristics of an acceptable evaluation for RI-ISI programs. It may be feasible to appropriately characterize the adequacy of GG and DC Cooks flooding analyst to support the RI-ISI evaluation in terms of the categories assigned to the flooding SRs. If the ASME standard will not identify an analysis equivalent to the RI-ISI analysis (perhaps because of the grouping in IF-C4 and screening in IF-D7), additional RI-ISI specific additions to the SRs (or the sufficiency of the SRs instead of the RI-ISI analysis) could be discussed.

This transmittal includes Draft RAI responses for the second set of RAIs from grand Gulf as well as those for first set again.
Let me know, if you have any comments or follow up questions that the licensee needs to prepare responses, and send those to us before the meeting.
