SUBJECT:
SUMMARY OF NOVEMBER 5, 2015, MEETING WITH SNC ON GSl-191 PROGRAM FOR THE VEGP (CAC NOS. MC4727 AND MC4728) On November 5, 2015, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and SNC representatives at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland.
The licensee's objectives in the meeting were to provide an overview of their risk-informed approach to addressing Generic Safety Issue (GSl)-191, "Assessment of Debris Accumulation on Pressurize-Water Reactor Sump Performance,"
and receive any comments, concerns or feedback from NRC staff. The meeting notice and agenda, dated October 20, 2015, is available in the Agencywide Documents Access and Management System (ADAMS) Accession No. ML 15308A214.
A list of attendees is provided as Enclosure
- 1. The licensee provided materials to support the meeting and its presentation in advance (ADAMS Accession Nos. ML 15293A180 and ML 15308A031).
The licensee revised the slides for the actual meeting (ADAMS Accession No. ML 15320A087).
SNC provided a brief description of VEGP, Units 1 and 2, with emphasis on similarities and differences with South Texas pilot. SNC provided a status update to the resolution schedule presented in the VEGP Proposed Path to Closure of GSl-191 dated May 16, 2013 (ADAMS Accession No. ML 13137A130.
In that letter, the licensee proposed the use of a risk-informed approach to the resolution of remaining GSl-191 issues. The licensee then provided an overview of their approach followed by more in depth discussions on the various technical aspects of their approach.
Discussions included:
- SNC its proposed modifications to the emergency core cooling system (ECCS) strainers and how this will result in increased submergence margins and . submergence of all strainers prior to recirculation in all postulated scenarios.
The NRC questioned the adequacy of the current strainer configurations that could result in the strainers not being completely submerged under all conditions.
The licensee that in the case of the small-break loss-of-coolant
- accident, there would not be containment spray, which would greatly reduce the material washed to the strainers and, thus, reduce the debris accumulation.
In these scenarios, there would still be adequate net positive suction head (NPSH) for the ECCS pumps.
- SNC described the modeling, quantification and probabilistic distributions of the input variables used to calculate the effects of debris. The licensee discussed modeling of scenarios ranging from fixing variables such at refueling water storage tank heights during suites of scenarios to deterministically reducing the number of scenarios and limiting the usage of input variable distributions.
The NRC staff discussion focused on the licensee's need to satisfy requirements while presenting an analysis that could facilitate the staff's review.
- SNC and the NRC staff discussed the assumptions concerning chemical precipitate formation.
The NRC staff questioned if the licensee had considered evaluating effects on a total amount of precipitate basis instead of separately evaluating calcium phosphate and aluminum hydroxide type precipitates.
SNC and the NRC staff also discussed the assumptions made about precipitate timing and whether the proposed method could be simplified to be ,r,nore consistent with approaches that the NRC staff has previously accepted.
q
- Throughout the presentation, SNC highlighted differences between their approach and the South Texas pilot.
- No regulatory decisions or commitments were made during the meeting.
Members of the public did not participate.
Furthermore, no Public Meeting Feedback forms were received.
