EPRI TR-3002000704, Seismic Evaluation Guidance: Augmented Approach for the Resolution of Fukushima Near-Term Task Force Recommendation 2. 1 Seismic, dated May 2013 (ML13102A142)

On May 19, 2015, Union Electric Co. (dba Ameren Missouri) received a Request for Additional Information (RAI) via email related to the Expedited Seismic Evaluation Process (ESEP) Report for Callaway Plant, provided under Reference 1. Ameren Missouri transmitted responses to the RAI questions via email.

On July 1 6, 201 5, a teleconference between Ameren Missouri and NRC staff was conducted, and at that time, it was determined that additional components needed to be added to Callaways Expedited Seismic Evaluation List (ESEL). The addition ofthese components required plant walkdowns, additional engineering analysis, and submittal of a supplement to the ESEP Report. Reference 2 served as a near term supplement to Reference 1.

Update to Section 6.2.2, Generic Screening Results, Table 6-1 : Summary of Generic Screening per NP-6041-SL, Table 2-4, 1.2g Screening Level 2.

Update to Section 6.3, Seismic Walkdown Approach 3.

Update to Section 6.6, Tabulated ESEL HCLPF Values (Including Key Failure Modes),

Table 6-3 :HCLPF Analysis Results 4.

Update to Section 9, References 5.

Update to Attachment A: Callaway Energy Center ESEL 6.

Update to Attachment B: ESEP HCLPF Values and Failure Modes Tabulation 7.

Insertion ofAttachment C: Seismic Review Team All equipment evaluated for the ESEP for Callaway Plant was found to have adequate capacity for the required seismic demand as defined by the Augmented Approach (ESEP) guidance (Reference 3), with the exception of certain relays located in Motor Control Centers (MCCs) NGO3C and NGO4C, the Condensate Storage Tank (CST), and the Refueling Water Storage Tank (RWST). The MCC relays were addressed with a procedural modification (FLEX Support Guideline revised). To address the CST, a new Hardened Condensate Storage Tank was constructed and put into service in May 2016.

Resolution of the RWST HCLEF (High Confidence of Low Probability of Failure) being less than RLGM (Review Level Ground Motion) is still in-progress.

This letter does not contain new commitments. Should you have any questions concerning the content of this letter, please contact Mr. Tom Elwood, Regulatory Affairs Supervisor, at (3 14) 225-1905.

to ULNRC-06291 Page 2 of 59

Table 6-1: Summary of generic screening per NP-6041-SL, Table 2-4, 1.2g Screening Level Equipment Type Generic Screening Criteria Screening Result Active valves Note (f) applies Although there are no extremely large extended motor operators on 2-inch or smaller piping, valves EPHV8808A/B/C/D are large MOVs with extended, heavy operators falling outside the NP-6041-SL Figure F-26 criteria and require evaluation.

Passive valves No evaluation required.

Atmospheric storage tanks Evaluation required.

HCLPF analyses required for the atmospheric storage tanks.

Pressure vessels Notes (h), (i) apply For the pressurized tanks on the ESEL, anchorage and load path were verified by bounding calculations using qualification reports during screening. Potential failure modes of the vessel bodies were address by walkdown and design review. The Safety Injection Tanks (Accumulators) were designed satisfactorily to Note (i) requirements; however, the anchorage requires evaluation.

Batteries and racks Note (k) applies.

Batteries are in plastic shell frames braced for overturning by steel rods and are designed for seismic loads. HCLPF analyses are required for the battery rack structure and anchorage.

Horizontal pumps No evaluation required.

Although no evaluation is required for the component per se, a HCLPF evaluation for the auxiliary feedwater turbine-driven pump is required.

Active electrical power distribution panels Notes (s) and (t) apply.

Note (s) was addressed by walkdown and design review. Where bounding analysis of anchorage configurations for the RLGM could not be provided, HCLPF analyses are required.

Relays are evaluated separately per Reference 5.

Passive electrical power distribution panels Note (s) applies.

Note (s) was addressed by walkdown and design review. Where bounding analysis of anchorage configurations for the RLGM could not be provided, HCLPF analyses are required.

Transformers Notes (u) and (v) apply.

The ESEL includes dry-type transformers. A design review verified coil restraint. HCLPF analysis of anchorage is required.

to ULNRC-06291 Page 3 of 59

Battery chargers & inverters Note (w) applies.

Per walkdown and design review, the items on the ESEL are solid state units. Where bounding analysis of anchorage configurations for the RLGM could not be provided, HCLPF analyses are required.

Instrumentation and control panels and racks Notes (s) and (t) apply.

Note (s) was addressed by walkdown and design review. Where bounding analysis of anchorage configurations for the RLGM could not be provided, HCLPF analyses are required.

Relays are evaluated separately per Reference 5.

Temperature sensors; pressure and level sensors.

Note (x) applies.

Note (x) was addressed by walkdown and design review. Sensors in the scope were typically mounted in-line on piping.

Relevant notes from NP-6041-SL Table 2-4

f.

Evaluation recommended for MOVs in piping lines of 2 inches diameter or less.

h.

Margin evaluation only needs to consider anchorage and supports.

i.

For vessels designed by dynamic analysis or equivalent static analysis enveloping vessel inertial and piping loading, only the anchorage and supports require evaluation. For vessel not meeting these criteria, all potential failure modes require evaluation.

k.

Batteries mounted in braced racks designed for seismic loads or qualified by dynamic testing do not require evaluation. Rigid spacers between batteries and end restraints are required. Batteries should be tightly supported by side rails.

s.

Walkdown should be conducted to verify that the instruments are properly attached to the cabinets.

t.

Relays, contactors, switches, and breakers must be evaluated for chatter and trip if functionality during strong shaking is required.

u.

Anchorage evaluation required.

v.

Liquid-filled transformers require evaluation of overpressure safety switches. The transformer coils should be restrained within the cabinet for dry transformers.

w.

Solid state units require anchorage checks. Others require evaluation.

x.

Insufficient data are available for screening guidelines. Emphasis should be on attachments.

UpdatetoSection6.3,SeismicWalkdown Approach

to ULNRC-06291 Page 5 of 59

6.3.1 Walkdown Approach Walkdowns were performed by two-person seismic review teams (SRTs) consisting of engineers with seismic experience. Walkdowns followed the guidance of Section 5 of EPRI 3002000704 and Section 2 of NP-6041-SL. The SRT used NP-6041-SL, Appendix F to evaluate item-specific equipment caveats. The SRT also recorded notes and took photographs of the items under review.

Four walkdown sessions have been performed as indicated below.

Various CEC Staff The walkdown findings for each item are documented in screening evaluation work sheets (SEWS). The SEWS notes also identify evaluations and reviews performed to support screening. The SEWS are included in Appendix C of Reference 10f. Also, Appendix A [10f] provides a concise summary of screening results in tabular format.

Qualifications of the SRT are provided in Appendix C.

6.3.2 Application of Previous Walkdown Information New seismic walkdowns were performed for ESEL equipment. Walkdown data ascertained in recent walkdowns of items as part of a seismic probabilistic risk assessment (S-PRA) were re-evaluated by the SRT and used for certain items. The results of the previous seismic margin evaluation, performed for the Seismic IPEEE program [11], were reviewed and used for background purposes only.

to ULNRC-06291 Page 41 of 59

Attachment B: ESEP HCLPF Values and Failure Modes Tabulation HCLPF values are listed in Table B-1. These notes are applicable:

1. The listed HCLPF value is for comparison to the horizontal PGA at the surface.

2. Items covered by the NP-6041-SL rule of the box (ROB) are identified in Table A-2 [9]. In each case, the HCLPF value for the parent item applies.

3. Where an anchorage HCLPF is performed but the component per se is screened, the equipment capacity is assigned based upon the 1.2g peak spectral acceleration coinciding with the 2nd screening lane of NP-6041-SL, Table 2-4. Since the WCGS RLGM has a peak spectral acceleration of 0.93g and PGA of 0.29g [Reference 10e], the 1.2g peak spectral acceleration corresponds with a PGA of 0.38g (witness 1.2g/0.93g*0.29g=0.38g). For equipment located above 40, the equipment capacity is conservatively assigned at the RLGM level of 0.29g.

4. For the CST and RWST only (TAP01 and TBN01, respectively), the applied ground motion was based on the GMRS (PGA = 0.29).

5. As a result of the relay chatter evaluation, additional items were added to the ESEL list for evaluation.
