20 14Q4242-RPT-004 Rev. 2 Page 6 of 33 I PURPOSE AND OBJECTIVE Following the accident at the Fukushima Dai-ichi nuclear power plant resulting from the March 1I, 2011, Great Tohoku Earthquake and subsequent tsunami, the Nuclear Regulatory Commission (NRC) established a Near Term Task Force (NTTF) to conduct a systematic review of NRC processes and regulations and to determine if the agency should make additional improvements to its regulatory system. The NTTF developed a set of recommendations intended to clarify and strengthen the regulatory framework forprotection against natural phenomena.
Subsequently, the NRC issued: a 50.54(f) letter on March 12,2012 (Ref. 1)requesting information to assure that these recommendations are addressed by ail U.S. nuclear power plants. The 50.54(f) letter requests that licensees and holders of construction permits under 10 CFR Part 50 reevalUate the seismic' hazards at their sites against present-day NRC requirements and guidance.
Depending on the comparison between the reevaluated seismic hazard and the current design basis, further risk assessment may be required.
Assessment approaches acceptable to the staff include a seismic-probabilistic risk assessment (SPRA), or a seismic margin assessment,(SMA).
Based upon the assessment results, the NRC staff will determine whether additional regulatory actions are necessary..
This report describes the Expedited Seismic Evaluation Process (ESEP) undertaken for Calvert Cliffs Nuclear Power Plant (CCNPP)." The intent of the ESEP is to perform an interim action in response to the NRC's 50.54(f) letter (Ref. 1) to demonstrate seismic margin through a review of a subset of the plant equipment that can be relied upon to protect the reactor core and containment following' beyond design basis seismic events.The ESEP is implemented using the methodologies in theL.NRC endorsed guidance in EPRI 3002000704,,Seismic Evaluation Guidance-Augmented Approach for the Resolution of:.Fukushima Near-Term' Task Force Recommendation 2:1: SeiSmic (Reft 2).The objective-of this report is.to provide summary information describing the ESEP evaluations and results. The level of detail provided in the report is iritended to'enable NRC tb understand the inputs used,,-h.e evaluatian.s-performed, and the decisionsmade as a result of.the interim evaluations.

Reactor inventory control and heat removal is accomplished by SIT tank injection.
One FLEX portable 500KW 480VAC diesel generator per unit is installed and connected to a 480 VAC Load Center. This repowered Load Center will provide power to battery chargers, SIT tank MOVs, and a charging pump for inventory restoration.
An alternate inventory control method is with a FLEX portable pump connected to the HPSI piping via the FLEX mechanical connections located in the Auxiliary Building.
Boration for shutdown margin is not needed for up to 32 hours, however, shutdown margin is 14Q4242-RPT-004 Rev. 2 Page 8 of 33 maintained by use of boric acid storage tanks with subsequent RCS injection using the Charging Pumps or a FLEX portable pump.In Mode 5 or 6 if the steam generators are unavailable RCS inventory can be maintained by gravity feed of the RWT or by use of portable flex pumps aligned to injection points to the RCS.Key reactor parameters are obtained via DC powered instrumentation or use of a 100KW 480 VAC generator powering a reactor MCC and the inverters backup bus. (This is the alternate strategy to load center repower)No specific Containment control is required in Phase 2 as both temperature and pressure stay within design limit for the first 72 hours of the event. Key Containment Parameters are obtained from DC powered instrumentation.
No specific Spent Fuel Pool level control is required in Phase 2 as both temperature and level stay within design limit for the first 65 hours of the event. Spent Fuel Pool level is obtained from the new wide range Spent Fuel Pool level instrumentation installed under Commission Order EA-12-051.
Flex Phase 3, greater than 24 hours, strategy relies on installed plant equipment, FLEX portable equipment, and off-site equipment from the National SAFER Response Center (NSRC). Reactor core cooling and heat removal are accomplished by continued use of the Phase 2 Strategies.
Restoration of these 4KV buses allows for restoration of more 480V busses for further redundancy.
Key reactor parameters are obtained via DC powered instrumentation or use of a vital AC instrumentation supported by portable FLEX or NSRC generators.
No specific Containment control is required in Phase 3 -as both temperature and pressure stay within design limit for the first 72 hoursof the event.Key containment parameters are obtained via DC powered instrumentation or use of a vital AC instrumentation supported by portable FLEX generators.
Spent Fuel Pool makeup is provided using either FLEX or NSRC portable pumps attached to exiting piping via flex mechanical connections.
Spent Fuel level is obtained from the new wide range Spent Fuel Pool level instrumentation installed under Commission Order EA-12-051.

===3.1 Equipment===
 
Selection Process and ESEL The selection of equipment to be included on the ESEL was based on installed plant equipment credited in the FLEX strategies during Phase 1, 2 and 3 mitigation of a Beyond Design Basis External Event (BDBEE), as outlined in the Calvert Cliffs Overall Integrated Plan &#xfd;(OiP)(Ref.3), and August 2013(Ref.4a), February 2014 (Ref. 4b), and August 2014 (Ref. 4c) six month updates, in Response to theMarch 12, 2012, Commission Order EA-12-049 (Ref. 3). The OIP provides the Calvert Cliffs FLEX mitigation strategy and serves as the basis forequipment selected for the ESEP.The scope of "installed plant equipment" includes equipment relied upon for the FLEX strategies to sustain the critical functions of core cooling and containment integrity consistent with the Calvert Cliffs OIP (Ref. 3). FLEX recovery actions are excluded from the ESEP scope per EPRI 3002000704 (Ref. 2). The' overall list of planned FLEX modifications and the scope for' -consideration herein is limited to those required to support core cooling, reactor coolant-inventory and sub-criticality, and containment integrity functions.
Portable and pre-staged FLEX equipment (not permanently installed)'
are excluded from the ESEL per EPRI 3002000704 (Ref.2).The ESEL component selection followed the EPRI guidance outlined in Section 3.2.of EPRI 3002000704 (Ref. 2).1. The scope of components is, limited to that required to accomplish the core cooling and containment safety functions identified in Table 3-2:of EPRI 3002000704.
The, instrumentation monitoring requirements for core cooling/containment safety. functions are.limited to those outlined Ien the EPRI 3002000704 guidance, and are a subset of those outlined in the Calie'rt Cliffs OIP (Ref. 3).2. The scope of,:components is, limited to installed plant equipment, and FLEX connections necessary to imnlpeme'nt the Calver-t Cliffs QIP (Ref73).as described in Section 2.3. The scope of components assumes the creditedFLEX connection modifications are implemented, and are limited to those requiredto support a single.

14Q4242-RPT-004 Rev. 2 Page 14 of 33 As these procedures are all approved and have an engineering basis they were used in conjunction with the OIP to generate the ESEL. It was not necessary to retrace these previously engineered actions through the P&ID's and logic diagrams as they have all been previously verified.Connection points identified in the'OIP for Phase 2 and 3 actions were included in the ESEL. At Calvert the electrical connections are being made via connection device (modified breaker)which will be placed In a spare cubicle, during Phase 2 or 3, on the designated load centers. All of these load centers are included in the ESEL as well as downstream load centers needed to perform Phase 2 and 3 FLEX activities.
These components were verified by review of the plants single line electrical drawings.Major mechanical, electrical, components, flowpaths and valves identified in the ESEL are the same as those identified in the EOPand the OIP. The ESEL used the guidance as outlined in EPRI 3002000704 (Ref. 2) and the appropriate exemptions as discussed below.3.1.2 Power Operated Valves Page 3-3 of EPRI 3002000704 (Ref. 2) notes that power operated Valves not required to change state are excluded from the'ESEL.
Page 3-2 also notes that "functional failure modes of electrical and mechanical portions of the installed Phase I equipment should be considered (e.g. RCIC/AFW trips)." TO addressthis concern, the following guidance is applied in the Calvert Cliffs ESEL for functional failure modes associated with power operated valves: " Power operated valves that remain energized during the Extehded Loss of all AC Power (ELAP) events (such as' DC powered valves), were included on the ESEL.* Power operated valves not required to change state as part ofthe FLEXW',itigation strategies were not included on the ESEL. The seismic event also causes the ELAP event; therefore, the valves are incapable of'spurious operation as they would be de-energized.
* Power operated valves not required to change state as part of the FLEX mitigation strategiesdUn"lr'ng Plh'ase "1, and arte reenergized and operated during subsequent Phase 2 and 3 strategies, were not evaluated for spurious valve operation as the seismic event that caused the ELAP has passed before the valves are re-powered.
3.1.3 Pull Boxes Pull boxes were deemed unnecessary to add to the ESELs as these components provide completely passive locations for pulling or installing cables. No breaks or connections in the cabling are included in pull boxes. Pull boxes were considered part of conduit and cabling, which are excluded in accordance with EPRI 3002000704 (Ref. 2).

14Q4242-RPT-004 Rev. 2 Page 23 of 33 6 SEISMIC MARGIN EVALUATION APPROACH It is necessary to demonstrate that ESEL items have sufficient seismic capacity to meet or exceed the demand characterized by-the RILGM. The seismic capacity is characterized as the peak ground acceleration (PGA) for which there is a high confidence of a low probability of failure (HCLPF); The PGA is associated with a specific spectral shape, in this case the 50/o-damped RLGM spectral shape... The HCLPF capacity must be equal to or greater than the RLGM PGA. The criteria for seismic capacity determination are given in Section 5 of EPRI 3002000704 (Ref. 2).There are two basic approaches for developing HCLPF capacities:
: 1. Deterministic approach using the conservative deterministic failure margin (CDFM)methodology of EPRI NP-6041, A Methodology for Assessment of Nuclear Power Plant Seismic Margin (Revision
: 1) (Ref. 7).2. Probabilistic approach using the fragility analysis methodology of EPRI TR-103959, Methodology for Developin6 Seismic Fragilities (Ref. 8).For Calvert Cliffs, the deterministic approach using the CDFM methodology of EPRI NP-6041 (Ref. 7) was used to determine.HC..C.PFs$
.,... .6.1 Summary of Methodologies Used Calvert Cliffs conservatively applied the methodology of EPRI NPO41 (Reft. -)t6 all items on the ESEL. The screening walkdowns used the screening tables from Chapter 2 of EPRI NP-6041 (Ref. 7). The walkdpwns were conducted by erngineer&#xfd;who as a minimum attendep the SQUG Wallkdown Screening and Seismic EvaluatiorTaIning "hu.waelkownswere documented on Screening' Evaluation Work 6t, fro I1l fr-,B041 (Ref. 7).' .&#xfd;."", -.' .I ' .- :: .. t ..., I " ."

Se" s ic, demand was based on the RLGM provided in Table 5.1-2 and Figure 5.1-1.6.2 HCLPF Screening Process The peak spectral acceleration for the RLGM equals to 0.264 g (Table 5.1-2). The screening tables in EPRI NP-6041 (Ref. 7) are based on ground peak spectral accelerations of 0.8g and 1.2g. All Calvert Cliffs ESEL components were screened against the caveats of the <0.8g column of Table 2-4 of NP-6041 (Ref. 7). For components located 40 feet above grade, 14Q4242-RPT-004 Rev. 2 Page 24 of 33 screening based on ground peak spectral acceleration is not applicable and additional consideration is required.
In accordance with Appendix B of EPRI 1019200 (Ref. 19), components that are above 40 feet from grade and have corresponding ISRS at the base of component not in exceedance of 1.2g in the component frequency range of interest may be screened using the caveats of the 1st screening column.6.3 Seismic Walkd0Wn Approach 6.3.1 Walkdown Approach Walkdowns for Calvert Cliffs were performiled in accordance with the crteria provided in Section 5 of EPRI 3002000704 (Ref. 2), which refers to EPRI NP-6041 (Ref. 7) for the Seismic Margin Assessment process., Pages 2-26 through 2-30 of EPRI NP-6041 (Ref. 7) describe the seismic walkdown criteria, including the following key criteria."The SRT [Seismic Review Team] should Owalk by" 100% of all components which are reasonably accessible and iK non-radioactive or low radioactive environments.
Seismic capability assessment of components which are inaccessible, in high-radioactive' environments, or possibly within contaminated containment, will have to rely more on alternate means such as photographic inspection, more reliance on seismic reanalysis, and possibly, smallerinspection teams and more hurried inspections.
A' 100% "walk by" does not mean complete inspection of each cO*mponent, nor does it mean requiring an electrician or other technician to de-energize and or panels for detailed inspection of all components.
This walkdown is not intended to be a QA orQC review or a review of the adequacy of the component at the SSE level.If the SRT has a reasonable basis for ass.uming that, the group of components are similar and are similarly anchored, then it is only necessary to inspect one component out of this group. The "similarity-basis" should be developed before the walkdown during the seismic capability preparatory work (Step 3),by reference to drawings, calculations or specificatiobs.:
The brie dcoiponent for each type which is selected should be thoroughly inspected which probably does mean de-energizing and opening cabinets or panels for this very limited sample. Generally, a spare representative component can be found so as to enable the ins'pection to be performed while the plant is in operation.
At least for the one component of each type which is selected, anchorage should be thoroughly inspected.
The walkdown procedure should be performed in an ad hoc manner. For each class of components the SRT should look closely at the first items and compare the field configurations with the construction drawings and/or specifications.
If a one-to-one correspondence is found, then subsequent items do not have to be inspected in as great a detail. Ultimately the walkdown becomes a "walk by" of the component class as the

This procedure for..I p,. .dn' tha th I. --_' "., * "'. .. .This .h inspectionishoufd be repeated for each component'class; althou6gL, during the actuaPI!ivafkdown the SRT may be inspectinog several classes of components in parallel.
If sero us exceptions to the drawings orquestionable construction Ipractices are fOund then the system or component class must be inspected in closer detail until the systematic deficiency is defined.The 100% "walk by" is to look for outliers, lack of similarty, anchorage which is~different..
from that shown on drawings or prescribed in criteria for that component, potential SI[Seismic Interaction]' (Ref 2, page 5-4) problems, situations thatmare at odds with the team members' past experience, and any other areas of serious seismic concern.

Other potential seismic interaction evaluations are "deferred to the full seismic risk evaluations performed in accordance with EPRI 1025287 (Ref. 14)."
14Q4242-RPT-004 Rev. 2 Page 26 of 33 The seismic walkdowns for Calvert Cliffs included as a minimum a walk-by of all the components on the ESEL with the exception of the items inside containment as they were not accessible at the time of the walkdowns.
 
====6.3.3 Significant====
 
Walkdown Findings Consistent with that guidance from NP-6041 (Ref. 7), no significant outliers or anchorage concerns were identified during the CalveIt Cliffs seismic walkdowns.
The following findings were noted during the walkdowns.
Several block walls were identified in the proximity of ESEL equipment.
These block walls were assessed for their structural adequacy to withstand the seismic loads resulting from the RLQM. For any cases where the block wall represented the HCLPF failure mode for.an ESEL item, it is noted in the tabulated HCLPF values in Attachments C and D described in Section 6.6.* The component 1PI-3988 was:screened in due to the fact that mcLunting
:is missing a manufacturer screw, howaver the anchorage was judged adequate and no HCLPF was calculated for the component.
The missing screw is required to be replaced in order for the component to.be screened out and.a-HCLPF greater than the RLGM could be credited:

Those evaluations included the following steps: :.. ,.. ., .** Performing seismic'capabili&#xfd;ty wilkdowns for 'equipment to evaluate the equipment installed plant conditions
* Performing screening evalUations using the s6reening tables, in EPRI NP-6041 (Ref. 7)as described in Section 6.2,and '* Performing HCLPF calculations considering various-failure modes4tat include both structural failure modes (e.g. anchorage, load path etc.) and functional failure modes.All HCLPF calculations were performed Using the CDFM methodology and are documented in CDFM'HCLPF calculation (Ref. 9.
14Q4242-RPT-004 Rev. 2 Page 27 of 33 Anchorage for non-valve components was evaluated either by SRT judgment or CDFM HCLPF calculation (Ref. 9).6.5 Functional Evaluation of Relays No relays existed in the Calvert Cliffs ESEL, therefore, no evaluations were performed for relay functionality.

Photos of Unit I containment items were used for the screening and HCLPF evaluations.
No photos were available for the Unit 2 items, Calvert Cliffs states that the two units are sufficiently similar to bd considered identical; therefore Unit 1 screening,'and HCLPF- evaluations were applied to Unit 2 containment items.7.2 Planned Walkdown I Evaluation.
Schedule I Close Out Since all items that were inaccessible during the ESEP were resolved by alternative means (i.e.confirmatory photos and similar states) to the satisfaction of the SRT, no. additional walkdowns are required.

14Q4242-RPT-004 Rev. 2 Page-29 of 33 8 ESEP CONCLUSIONS AND RESULTS 8.1 Supporting Information Calvert Cliffshalsprrmed the le P, as qn interim ac ton in response j0 the NRC's 50.54(f)Screening and.Pripntization,lefttpridattedMay,9,, 201.4 (Ref. 13). Itwa.iperformed using the methodologies in the NRC endorsed guidance in EPRI;300200Q7r04 (R0f02). -n ...The ESEP provides an important demonstration of seismic margin and expedites plant safety enhancements through evaluations and.-potbntiail nr-bri modifications of I2la1t equipment that can be relied upon to protect the reactor core following beyond design basis seismic events.The ESEP is'padrbf the overall dC alvert Cliffs respdhse to'1he NRC's 50564(f) letter(Ref.
1). On March 12, 2014, NEI submitted to the NRC results of a study (Ref. 11) of seismic cord'damage risk estimates based on updated seismic hazard information as it applies to operating nuclear reactors in the Central and Eastern United States (CEUS). The study concluded that "site-specific seismic hazards show that there has not been an overall increase in seismic risk for the fleet of U.S. plants" based on the re-evaluated seismic hazards. As such, the "current seismic design of operating reactors continues to provide a safety margin to withstand potential earthquakes exceeding the seismic design basis." The NRC's May 9, 2014 NTTF 2.1 Screening and Prioritization letter (Ref. 13) concluded that the "fleetwide seismic risk estimates are consistent with the approach and results used in the GI-1 99 safety/risk assessment." The letter also stated that "As a result, the staff has confirmed that the conclusions reached in GI-199 safety/risk assessment remain valid and that the plants can continue to operate while additional evaluations are conducted." An assessment of the change in seismic risk for Calvert Cliffs was included in the fleet risk evaluation submitted in the March 12, 2014 NEI letter (Ref. 11) therefore, the conclusions in the NRC's May 9 letter (Ref. 13) also apply to Calvert Cliffs.In addition, the March 12, 2014 NEI letter (Ref. 11) provided an attached "Perspectives on the Seismic Capacity of Operating Plants," which (1) assessed a number of qualitative reasons why the design of SSCs inherently contain margin beyond their design level, (2) discussed industrial seismic experience databases of performance of industry facility components similar to nuclear SSCs, and (3) discussed earthquake experience at operating plants.The fleet of currently operating nuclear power plants was designed using conservative practices, such that the plants have significant margin to withstand large ground motions safely.This has been borne out for those plants that have actually experienced significant earthquakes.
The seismic design process has inherent (and intentional) conservatisms which result in significant seismic margins within structures, systems and components (SSCs). These conservatisms are reflected in several key aspects of the seismic design process, including:
14Q4242-RPT-004 Rev. 2 Page 30 of 33* Safety factors applied in design calculations
* Damping values used in dynamic analysis of SSCs* Bounding synthetic time histories for in-structure response spectra calculations
* Broadening criteria formn-structure response spectra Response spectra enveloping criteria typically used in SSC analysis and testing applications Response spectra based frequency domain analysis rather than explicit time history based time domain analysis ..Bounding requirements in codes and standards* Use of minimum strength requirements of structural components (concrete and steel)* Bounding testing requirements Ductile behavior of the primary materials (that is, not crediting the additional capacity of materials such as steel and, reinforced concrete beyond the essentially elastic range These design practices combine to result in margins such that the tSCs wIll continue t fulfill their functions at ground motions well above the SSE.8.2 Summary of ESEP Identified and Planned Modifilations, The results of the Calvert Cliffs ESEP performed as an iptenm ,action in response to.the NRC's 50.54(f) letter (Ref. 1) using the methodologies in the NRC endorsed guidance in EPRI 3002000704 (Ref. 2) show that all equipment evaluated are adequate in resisting the seismic loads expected to result from the site RLGM. Therefore, no plant modifications are required as a result. of the Calvert Cliffs ESER.8.3 Modification Implementation Schedule No modifications are required.8.4 Summary of Regulatory Commitments
