D.C. Cook 50.54(f) SPRA Submittal - Completeness Review Done and Path Forward Date: Monday, December 09, 2019 6:01:00 PM Good afternoon Joe, The purpose of this email is to inform you that: 1) the NRC staff has finished its completeness (similar to an acceptance) review of the D.C. Cook 50.54(f) seismic probabilistic risk assessment (SPRA) submittal (ADAMS Accession No. ML19310D805), 2) the submittal contains sufficient information to proceed to stage 2 - the detailed audit review, 3) to share our proposed review timeline, and 4) to request that information be provided on the DC Cook SPRA e-Portal audit folder to support the staffs detailed review of the submittal.
Completeness (Acceptance) Review The staff has completed its Completeness review (Stage 1) and has determined that sufficient information has been provided to proceed to Stage 2.
The tentative review schedule for the staffs review can be found below.
Proposed Review Timeline (subject to change)
Stage (1): Completeness Review - DONE Stage (2): Verify that SPRA is Suitable for Decision-Making and Develop Recommendation Prepare first draft of the Technical Review Checklist (ADAMS Accession No. ML17041A327) - March 2020 Clarification call with licensee and NRC staff (if needed) - March 2020 Updated Technical Review checklist using responses to clarification questions and determine tentative recommendation - June 2020 Technical Review Board Briefing - July 2020 Senior Management Review Panel (SMRP) Briefing - August 2020 Issue Staff Response Letter - September 2020, unless SMRP concludes that further evaluation (Stage 3) is needed
Request for e-Portal Information The staffs review of the SPRA report follows the generic audit plan dated July 6, 2017 (ADAMS Accession No. ML17177A446). The audit process is used to confirm statements in the SPRA submittal. To support the Staffs review, please make the following documents (or portions supporting the submittal) and information available in your e-Portal:
- 1. PWROG-18062-P, Revision 0 Peer Review of the D.C. Cook 1&2 Seismic Probabilistic Risk Assessment, dated January 2019. [Reference 6].
- 2. Report AEPDCC-00058-REPT-001, SPRA F&O Independent Assessment and Focused-Scope Peer Review, Donald C. Cook Nuclear Plant Units 1 and 2, Revision A. [Reference 64]
- 3. CNP Document 15C4313-RPT-002, Fragility Analysis Plan for Cook Nuclear Plant (CNP) Unit 1 & 2 Seismic PRA, Revision 3. [Reference 30]
- 4. CNP document 15C4313-RPT-003, Summary of Building Response Analysis for the Cook Nuclear Plant (CNP) Unit 1 & Unit 2 SPRA, Revision 4. [Reference 63]
- 5. CNP document 15C4313-CAL-010 Response Analysis of Auxiliary Building, Revision 3. [Reference 69]
- 6. Fragility Analysis Report [Reference 40 and any others]; specifically, appropriate documentation that shows estimation of fragility parameters for the following structures, systems, and components:
- a. Turbine Building Collapse, SF-NSCIBTB1 (Table 5.4-2).
- b. Seismic Induced Very Small LOCA, SF-VSLOCA (Table 5.4-2).
- c. Seismic Failure of Relay Group D_1, RELAY_D_1 (Table 5.4-2).
- d. Seismic Failure of Train CD Battery Rack, SF-BATCD (Table 5.4-2).
- e. SC-I Building Auxiliary Building, SF-SCIBAB (Table 5.5-2).
- f. Supplemental Diesel Generator System Components, SF-SDG (Table 5.5-2).
- g. Seismic-Induced Fire Originating from Boiler, SF-NSFIRE30 (Table 5.5-2).
- h. SC-I Building - Containment Building, SF-SCIBCONT (Table 5.5-2).
- i. Control Room Ceiling Section 3, SF-CRCEIL-3 (Table 5.5-2).
In addition, please include the structural analysis of the building where these components are located so that the staff can assess the process for development of the In-Structure Response Spectra (ISRS).
- 7. SPRA Peer Review Reports (Full-Scope, Focused-Scope, and Close-Out, as applicable) [if any others, in addition to References 6 and 64 noted above]
- 8. SPRA Human Reliability Analysis Notebook [Reference 47 and any others]
- 9. SPRA Plant Response Notebook
- 10. SPRA Quantification Notebook [Reference 12]
- 11. SPRA Modeling Notebook [Reference 50]
- 12. Seismic-Induced Fire and Flood Assessment
- 13. Uncertainty and Sensitivity, if separate from Quantification Notebook
- 14. SPRA Relay Chatter Impact Evaluation [Reference 46]
- 15. Internal Events PRA Peer Review Report (Full-Scope, Focused-Scope, and Close-Out, as applicable) [Reference 60, or any others]
- 16. Confirmation that the licensees SPRA model incorporates the latest resolutions to all IEPRA peer review finding level F&Os (open as well as closed). Provide justification that the exclusion of those resolutions from the SPRA as well as dispositions of open findings does not significantly change the corresponding results.
The rationale for requesting items 15 and 16 is to determine the acceptability of the base IEPRA model.
Please feel free to give me a call if you have any questions regarding this email of if you would like to discuss this request. Just to confirm for you, I will be the primary NRC project manager for this review, so you can reach out to me as your primary POC. Milton will still be involved as a backup resource, so he is still available as well.
We may have additional information needs in the near future and we will communicate those as the review progresses.
Please let me know as you are able upload these documents to the DC Cook SPRA audit folder.
Thank you in advance.
