Subject:
Preliminary RAIs for Section 3.10
- 1. Reference is made to IEEE 344-1987 in Tables 3.10-1 and 3.10-2. However, IEEE 344-1987 is not mentioned in Section 3.10.1, "Seismic Qualification Criteria." Nor is this discussed in the referenced Section 3.7.3.16.
Clarify how IEEE-1987 is used in a similar manner to how you discuss the use of IEEE 344-1971 and IEEE 344-1975.
- 2. Table 3.10.1, "WBNP Instrumentation and Electrical Equipment," in WBN- 2 FSAR Section 3.10 contains three new rows related to certain equipment and their qualification methods and test methods. The first new row in Table 3.10.1 states that the "Control Instrument Loops" (Unit 2) located at "multiple locations" were qualified by "Test" using "multiaxis" test method performed by "Nuclear Qualification Services."
Clarify if the "Test" method and the "Test" results were reviewed by the NRC staff and provide a reference that documents the review conclusion. If they were not reviewed by the NRC staff, submit the results of the test for the staff's review.
The second new row in Table 3.10.1 states that "Panels 2-L-11A and 2-L-11B" were qualified by "Analysis."
(1) Clarify if the Analysis mentioned in the second new row in table 3.10.1 was performed in-house by the TVA staff; if not, complete the Table 3.10.1 giving the name of the company, which performed the Analysis. (2) Also, clarify if the "Analysis" method and the Analysis results were reviewed by the NRC staff and provide a reference that documents the review conclusion. If they were not reviewed by the NRC staff, submit the results of Analysis for the staff's review.
The third new row in Table 3.10.1 states that the qualification method for the equipment (PAMS Cabinet and Components and Main Control Room Components) is "Analysis (to be performed)."
Provide a target date when this analysis will be performed, submit the results of the Analysis for the staff's review, and amend the FSAR as needed.
- 3. In several locations in FSAR Section 3.10 (e.g., pages 3.10-11, 3.10-12, and 3.10-18), the word "LATER" is inserted before a Reference or a report.
If this word LATER refers to future action, provide a target date to provide these reports and the results of the qualification Tests / Analysis included in these reports for the staff's review.
- 4. The numbering of the Unit 2 list on page 3.10-4 is not consistent with the numbering referenced by the text below the list.
(1)Correct the numbering to clearly identify the references associated with the items in the list. (2)The Nuclear Instrumentation System Power Range Electronics appears to be a new item added to the list for Unit 2. Clarify which reference documents its qualification testing. Provide the results of the test or analysis.
- 5. Page No. 3.10-4 in FSAR Section 3.10.1 lists several new items of instrumentation and electrical equipment requiring seismic qualification. It is stated on page 3.10-6 of Section 3.10.1 that seismic qualification testing of items 11 and 12 is documented in a new Reference 25. Provide a copy of Reference 25 for the staff's review.
- 6. On line 3 from the bottom of Page No. 3.10-4 in FSAR Section 3.10.1, a new Reference 33 is cited. However Reference 33 is not actually included in the list of References on page 3.10-12.
Correct the reference.
