INDIVIDUALPLANT EXAMINATZON OF EXTERNAL EVENTS (IPEEE)

FOR SEVERE ACCIDENT VULNERABILITIES SEISMIC EVALUATION REPORTS REQUEST FOR ADDITIONAL INFORMATION In GL 87-02, NRC established the process for resolution of USI A-46 and encouraged the affected licensees to participate in a generic program.

Supplement 1 to GL 87-02, required a response that included a commitment to the Generic Implementation Procedure, Revision 2, (GIP-2) prepared by the Seismic Qualification Utility Group (SQUG),

a schedule for implementation of the GIP-2, and submission of a report summarizing the results of the USI A-46 Program.

By letters to NRC dated September 21,

1992, January 19,

1993, and March 19,

1996, TVA committed to implement the GIP-2, including the clarifications, interpretations, and exceptions in the NRC Supplemental Safety Evaluation Report Number Two (SSER-2),

and to communicate to the staff any significant or programmatic deviations from the GIP-2 guidance.

For BFN Units 2 and 3, TVA committed to submi't the results of the USI A-46 evaluation by June 28, 1996.

TVA performed combined USI A-46 and seismic IPEEE walkdowns in accordance with the SQUG GIP-2.

Outliers (i.e.,

items of equipment that did not meet the walkdown screening criteria) were identified during the seismic evaluations for mechanical and electrical equipment and electrical relays.

Seismic Evaluation and Relay Reports listed the outliers identified during these evaluations.

The Seismic Evaluation Reports for BFN Units 2 and 3 were submitted by TVA letter dated June 28, 1996.

In that letter, TVA committed to resolve the outliers for BFN Unit 2 prior to restart from the Cycle 9 (October 1997) refueling outage and for Unit 3 prior to restart from its Cycle 7

(March 1997) refueling outage.

TVA also committed to submit completion

reports, as specified in the GIP-2, for BFN Units 2 and 3

4l 4l r,

I J

upon completion of the outlier resolution.

The completion reports for BFN Units 2 and 3 were submitted by TVA letters dated November 18,

1997, and April 11, 1997 respectively.

In a letter dated July 13,

1998, the NRC,staff identified questions regarding its revi'ew of the BFN Units 2 and 3

Seismic Evaluation Reports.

The NRC questions and the corresponding TVA responses are provided below.

NRC Re est (Item 1)

Referring to the in-structure response spectra (ISRS) discussed in your response (Reference

1) to the Nuclear Regulatory Commission (NRC's) request in.Supplement No.

1 to Generic Letter 87-02, dated May 22,

1992, the following information is requested:

a) Identify structure(s) which have ISRS (5 percent critical damping) for elevations within 40-feet above the effective grade, which are higher in amplitude than 1.5 times the Seismic Qualification Utilities Group bounding spectrum.

b) With respect to the comparison of equipment seismic capacity and seismic

demand, indicate which method in Table 4-1 of GIP-2 was used to evaluate the seismic adequacy for equipment installed on the corresponding floors in the structure(s) identified in item (a) above.

If you have elected to use Method A in Table 4-1 of the GIP-2, provide a technical justification for not using the ISRS provided in Reference 1.

c)

For the structure(s) identified in item (a)

above, provide the ISRS designated according to the height above the effective grade.

If the ISRS identified in Reference 1 were not used, provide the response spectra that were used to verify the seismic adequacy of equipment within the structures identified in item (a) above.

Also, provide a comparison of these spectra to 1.5 times the bounding spectrum.

d) Identify all the safe shutdown equipment list (SSEL) equipment installed in the Diesel Generator Building identified in item (a)

above, and provide information in a tabular form with the pertinent information similar to those in Appendix D of Enclosure 1 and Appendix A of, Enclosure 2 to Reference 2, for the verification of seismic adequacy of each equipment identified, in view of the concerns identified in items (b) and (c) above.

E-2

Cl F

'k

TVA Res onse a)

The following structures have in-structure response spectra higher in amplitude than 1.5 times the SQUG bounding spectrum for elevations about 40 feet above the effective grade.

1. Reactor Building

2. Diesel Generator Building It should be noted that the spectral exceedance for the Reactor Building is at frequencies less than 8 hertz.

The spectral exceedance for the Diesel Generator Building is at frequencies greater than 8 hertz.

b) In general, Method A in Table 4-1 of GIP-2 was used for comparison of equipment seismic capacity and seismic demand for equipment located about 40 feet above the effective grade and having fundamental frequency greater than 8 hertz.

Comparison of SQUG bounding spectrum and ground response spectra at effective grade elevations for the Reactor Building and Diesel-Generator Building are shown in Figures 3-1 and 3-2 of Enclosure 1 to Reference 2, respectively.

It should be noted that the ISRS for the Diesel Generator Building were developed by application of specific seismic considerations such as inclusion of soil amplification of 1.6 to obtain the free field input motion at the base of the structure and use of very conservative structural modeling techniques.

TVA used the ISRS (Method B) for the quantitative evaluation (e.g.

anchorage) portions of the A-46 review at BFN to incorporate additional conservatism in the most critical portions of the GIP process.

c) In-structure response

spectra, designated according to the height of up to about 40 feet above the effective

grade, are provided in Attachments 1-C-1 and 1-C-2 of this enclosure for Reactor Building and Diesel Generator Building, respectively.

d) Tabulated information, similar to that in Appendix D of Enclosure 1 and Append'ix A of Enclosure 2 to Reference 2, for safe shutdown equipment list (SSEL) equipment installed in the Diesel Generator Buildings is provided in Attachments 1-D-1 and 1-D-2 of this enclosure.

In summary, TVA implemented its program to resolve USI A-46 in a manner consistent with the requirements of GIP-2.

TVA was aware of issues NRC had relative to the use of GIP Method A and took proactive steps to ensure t:hat an adequate seismic evaluation was performed for structures that were founded on shallow soil conditions.

The ground mot:ion (freefield) estimate accounted for soil amplification effects (1.6),

was conservatively developed and implemented in accordance with the recommendations developed by the SQUG Steering Committee.

Additionally, TVA augmented the adequacy of equipment weak link (anchorage) by computing the seismic demand, utilizing ISRS in lieu of 1.5 times ground

motion, as a demonstration of seismic capacity exceeding seismic

demand, which provides more safety margin than that required by Method A rules.

NRC Re est (Item 2)

In Section 5.1.3 of Enclosure 1 to Reference 2,

you indicated that bounding calculations were performed to address the seismic adequacy of the anchorage.

Stat:e whether you followed the guidelines provided in Appendix C

of the GIP-2 procedure in determining nominal allowable capacities and capacity reduction factors.

Submit sample calculations for each of the following anchor types:

expansion

anchor, welded anchor, cast:-in-place bolt and headed

studs, cast-in-place J-bolt; and grouted-in-place bolt, using the worst-case bounding anchorage evaluations for various equipment classes (MCC, switchgear, transformers, distribution panels, battery chargers, electrical cabinets and mechanical equipment, et:c.)

TVA Res onse The following table provides a summary of the anchorage evaluations performed for the various types of anchors covered in Appendix C of GIP-2.

Equipment class of each of the items selected is also provided.

Seismic adequacy of the respective anchorage are evaluated in accordance with the guidelines provided in Appendix C of GIP-2, as applicable.

.selected'SEL items or calculation packages as shown, all of which are provided in Attachment

2. of this enclosure.

NRC Re est (Item 3)

Indicate whether an anchor type, e.g.,

lead cinch anchor,,

not covered by the GIP-2 was used for SSEL equipment anchorage at Browns Ferry Nuclear (BFN) Units 2 and 3 during the Unresolved Safety Issue (USI) A-46 walkdown. If yes, how did you resolve:the issue?

TVA Res onse The USI A-46 in-plant walkdown and evaluation did not identify any anchor types not covered by the GIP-2 (e.g.

lead cinch anchors).

NRC Re est (Item 4)

You indicated in Appendix E of Enclosure 1 to Reference 2

that an anchorage evaluation was performed for equipment (CRD/hydraulic control unit, I.D. Nos.

2-HCU-85, 1-185 and 3-HCU-85, 1-185)',

which was not specifically addressed by the GIP-2.

Provide detailed information (equipment dimension, anchorage type and dimension, etc.) with your evaluation for the verification of.seismic adequacy of this equipment and anchorage.

E-5

TVA Res onse CRD/Hydraulic control units (SSEL Nos.

0001 and 30001; Equipment ID Nos.

2-HCU-85-1 to -185 and 3-HCU-85-1 to -185, respectively) are NSSS equipment and were seismically qualified by GE (see attached letter in SEWS for SSEL No.

0001) using conservative seismic demand loads (1 percent damped

.ISRS at El. 565').

Anchorage for these units were evaluated and shown to be adequate in the SEWS for SSEL No. 0001.

Detailed equipment information such as dimension and anchor type are included in the above SEWS.

Copies of SEWS for SSEL Nos.

0001 and 30001 are provided in Attachment 4 of this enclosure.

NRC Re est (Item 5)

In Section 6.1.1 of Enclosure 1 to Reference 2,

you stated that no large vertical flat-bottom tanks are on the BFN Seismic Review SSEL.

Since USI A-40 is a part of USI A-46 for BFN, clarify whether this statement is still true.

If not, provide the resolution of these large vertical flat-bottom tanks for closure of USI A-40.

Indicate whether you used the SMA methodology described in the Electric Power Research Institute NP-6041 report for the resolution of tanks and heat exchangers.

The staff has noted that the SMA methodology is known to yield analytical results which may not be as conservative as those obtained by following the GIP-2 guidelines, hence, it is generally not acceptable for the USI A-46 program.

For each deviation from the GIP-2 guidelines, in situations where the margin methodology is utilized, identify the nature and the extent of the deviation, and provide a technical justification for its acceptance.

TVA Res onse The only large flat-bottom tanks at Browns Ferry are the condensate

storage, waste lubrication oil, fuel oil, and demineralized water storage tanks.

None of these tanks are safety related tanks and were not needed to resolve issues related to the USI A-46 or IPEEE external events program.

These tanks are located in the yard, outside critical BFN structures.

The NRC conclusion on USI A-40 states "The staff has therefore concluded that backfit of the proposed seismic design provisions is not necessary except for the design of safety-related

large, above ground tanks."

Since BFN has no large flat-bottom safety related tanks, TVA considers USI A-40 resolved.

NRC Re est (Item 6)

You indicated'n Section 6.1.2 and Appendix H-2 of Enclosure 1 to Reference 2 that a heat exchanger (Equipment I.D. No.

3-HEX-74-900D) was not covered by the GIP-2 procedure and was classified as an outlier.

Provide, for staff review, the calculation (Calculation 50147-C-004) for the resolution of the outlier.

Provide, also the information concerning the seismic adequacy of the following tanks, including the Screening Evaluation Work sheets (SEWS) for each item:

(1)

CAD/Nitrogen tanks, (2)

DG 7-day fuel oil tanks, and (3) diesel generator starting air receivers.

TVA Res onse Equipment ID No. 3-HEX-74-900D (SSEL No.

31042) is the RHR heat exchanger 3D. It is a vertical heat exchanger and as such i.s, not covered in GIP-2, and therefore, was classified as an outlier.

Seismic evaluation of the heat exchanger supports and anchorage, taking into consideration nozzle loads from existing piping analysis, was performed and documented in calculation 50147-C-004.

A copy of the calculation is provided in Attachment 6 of this enclosure.

1) CAD/Nitro en Tanks CAD/Nitrogen tanks are listed as SSEL No.

6001 (0-TNK 635-A) and SSEL No.

6025 (0-TNK-84-636-B).

Seismic assessment including anchorage and support, were evaluated in SEWS for SSEL No.

6001 following the GIP-2 Section 7

guidelines and shown to be adequate.

Copies of the SEWS for the above tanks are provided in Attachment 6-1 of this enclosure.

2)

DG 7-Da Fuel Oil Tanks There are a total of 24 tanks listed in the BFN 2 and 3

SSEL (3 per diesel generator).

Per drawing review, tanks are encased in reinforced concrete.

Because the tanks are encased in concrete and are part of the diesel generator foundation no inertial failure modes were judged credible.

Additionally, the diesel generator is rigidly attached to the building foundation mat, therefore there are no differential displacement concerns on the attached piping.

Copies of representative SEWS (SSEL Nos.

7002, 7003, and 7004) and associated drawings are provided in Attachment 6-2 of this enclosure.

E-7

II

3)

DG Startin Air Receivers There are a total of 80 air receiver tanks listed in the BFN 2 and 3 SSEL (10 per diesel generator compartment).

Both tanks and supports were judged to be seismically rugged based on the small tank size and robust support configuration.

Copy of representative SEWS (SSEL No.

7005) is provided in Attachment 6-3 of this enclosure.

NRC Re est (Item 7)

The GIP-2 procedure recommended that the licensee perform a

limited analytical evaluation for selected raceways and cable trays.

The procedure recommended that when a certain cable tray system can be judged to be ductile and if the vertical load capacity of the anchorage can be established by a load check using three times the dead weight, no further evaluation is needed to demonstrate lateral resistance to vibration from earthquakes.

a) Provide descriptions of typical configurations of your ductile raceways (dimension, member size,

supports, etc.)

b) Discuss the configuration of raceways and cable trays that are outside of the experience

data, and provide an estimate of the percentage of these installations with respect to the whole population of raceways.

Discuss your approach for the evaluation and disposition of these installations.

TVA Res onse a) Typical raceway supports at BFN which are determined to be ductile are rod hung cable tray and conduit trapeze support systems.

The support rods vary in diameter from 8 to

~4 inch and are between 4 to 12 feet in length.

In addition, strut channel frames with standard clip angle

details, such as Unistrut P1000 and P1001 or equivalent

sections, are also utilized as raceway supports at BFN.

These systems are similar in nature to those described in Section 8 of GIP-2.

b)

The in-plant walkdown and evaluation did not identify any raceway configurations that did not meet the general characteristics as outlined in GIP-2, Section 8 seismic review guidelines.

Less than about 5 percent of the

0 41

raceway support configurations were initially classified as outliers.

These outliers were subsequently resolved by additional evaluations or modifications.

NRC Re est (Item 8)

Section 7.3 and Appendix 1-2 of Enclosure 1 to Reference 2

presents cable tray and conduit raceway outliers and their resolutions.

Provide calculations for the following outliers:

Nos.

19-02, 44-01, 22-03, and 35-01.

TVA Res onse Resolution of the requested raceway outliers are briefly described

below, along with the respective reference documents.

Copies of the referenced calculations are provided in the attachments listed below.

1) Outlier 19-02:

Edge distance violation on cable tray support Rod hung trapeze support meets the GIP-2 Limited Analytical Review (LAR) requirements, ignoring the brace support with anchors less than minimum edge distance.

Refer to TVA calculation CD-Q2999-940343,-

pages 45-50 for detailed calculations.

A copy of this calculation is provided in Attachment 8-1 of this enclosure.

2) Outlier 44-01:

Protruding shell anchors on 3 conduit supports TVA calculation CD-Q2999-940343 was developed to resolve this outlier.

A copy of this calculation is provided in Attachment 8-2 of this enclosure.

3. Outlier 22-03:

Insufficient anchor embedment on support's base plate to ceiling Support anchorage was evaluated, taking into consideration only those anchors with no embedment

concerns, and was shown to meet the GIP-2, Limited Analytical Review (LAR) requirements.

Refer to TVA calculation CD-Q0000-931227, pages 200-204 for detailed calculations.

A copy of this calculation is provided in Attachment 8-3 of this enclosure.

4) Outlier 35-01:

Reference TVA calculations CD-Q0000-931227, page 180 and CD-Q3999-890678 for detailed evaluations.

Copies of these calculations are provided in Attachment 8-4 of this enclosure.

NRC Re est (Item '9)

If thermal-lag panels, are attached, to a cable tray system, discuss how the changes in weight have been incorporated in the GIP evaluation of these systems and their supports.

TVA Res onse BFN has no Thermo-Lag panels attached to cable tray.systems.

However, BFN has approximately 200 feet of electrical conduit and several junction boxes that are covered by Thermo-Lag panels.

These Thermo-Lag installations are located in the Intake Pumping Station.

The effect of the weight. change as a result of the Thermo-'Lag panels was included in the evaluation of the raceways.

These raceways were not qualified by GIP-2 methods.

These raceways were seismically qualified by use of the TVA standard for Thermo-Lag construction.

The TVA standard has been previously reviewed and accepted by NRC for applications at TVA facilities.

NRC Re est (Item 10)

In Appendix C of Enclosure 1 to Reference 2, there are equipment items designated as "ROB" class, which were seismically verified using the "rule of box" as outlined in GIP-2.

Identify which "Box" each of the following equipment items belongs to and provide, for staff review, the evaluation performed to determine the seismic adequacy of each item, including mounting and/or anchorage evaluations:

Detailed evaluation of'hese SSEL equipment

items, including description of equipmen't dimensions and properties, anchorage configurations, seismic capacity versus

demand, frequency estimation and justification of seismic

adequacy, are contained in the respective SEWS packages.

SEWS for these

items, along with other related SEWS and documentation, are provided in Attachment 11 of this enclosure.

It should be noted that a specific frequency calculation was not performed for sub-assemblies unless a,specific component challenged the judgment of the seismic review team members during the A-46 program.

The program relied on the aspect that trained seismic review team members walkeddown each A-46 component and utilized their best, engineering judgment to determine if any outliers, such, as low frequency devices,

,or improper mounting configurations existed.

For example, the frequency of a door panel that supported A-46 subassemblies (SSEL No.

9018')

was calculated to verify it had a frequency, of greater than 8 hertz.

NRC Re est (Item 12)

In Appendix F-2 of Enclosure 1 to Reference 2,

SSEL item Nos.

9119,9122, 9125, and 9128 (250 V Battery SB-A, B,

C, and D) are batteries with multi-tiered racks.

You concluded that these batteries on racks met the intent of GIP-2 caveat GR4 for batteries on racks even though the GIP-2 caveat limits the applicability of Generic Equipment Ruggedness Spectra only for batteries supported on two-step or single-tiered racks with longitudinal cross-braces.

The items should have been identified as outliers and resolved accordingly.

The footnote indicated that these racks are represented in a portion of the seismic experience database.

Provide, for staff review, the documentation of this seismic experience

database, and justify the seismic adequacy of these battery racks and the batteries at BFN, taking into account the potential amplification through the racks to the center of gravity of the batteries.

Also submit the SEWS for this items.

TVA Res onse The battery racks had been designed and modified prior to the USI A-46 program.

The newly designed racks were modified to allow the installation of new batteries at BFN.

The racks were constructed of 4x4 tube steel with longitudinal bracing and are qualified using conservative classical analytical methods.

Seismic analysis of these racks is documented in TVA calculation CD-Q0248-910431.

A copy of this calculation is provided in Attachment 12-1 of this enclosure.

The primary qualification of these battery racks was based upon GERS and classical engineering methods (frequencies above 8 hertz, horizontal and 20 hertz vertical with adequate strength),.

The footnote as shown in Appendix F-2. of Enclosure 1 to Reference 2 was intended to supplement the primary qualification.

Detailed evaluation is contained in the SEWS.

As requested, examples have been extracted from the seismic experience database with multi-tiered single bay battery racks of robust construction (steel channel sections),

similar to those at BFN which are constructed of 4x4 tube steel.

These racks performed well during the 1994 Northridge earthquake.

Photographs of undamaged battery rack insi allations, such as the telecommunication. facilities in San Fernando and Sylmar Granada, along with BFN E-16

ll

installations and copies of the SEWS for the above battery racks (SSEL Nos.

9119, 9122,

9125, and 9128) are provided in Attachment 12-2 of this enclosure.

In your response (Reference

3) dated January 19, 1993, to NRC request for additional information dated November 19,

1992, you stated in item No.

6, that Tennessee Valley Authority did not intend to change the licensing basis for BFN, Units 1, 2,

and 3, prior to the receipt of the NRC staff's plant-specific safety evaluation.

However, in your Amendment No.

10, dated July 22, 1993, to the BFN Final Safety Analysis Report (FSAR),

you have revised your licensing basis to use the guidelines and criteria of USI A-46 and associated Seismic Experience Database as an alternative method of equipment (Paragraph C.6.3.3 of Appendix C to Updated FSAR dated July 22, 1993).

As of the date of this letter, the staff has not issued its final SE on the USI A-46 implementation at BFN.

The staff is unaware

II II I

whether the GIP-2 procedure has been employed by TVA in actually making a change to the facility outside the scope of USI A-46.

In order for the staff to complete its review of USI A-46 implementation at BFN, the staff requests that you (1) submit, for staff review, the complete documentation associated with your 10 CFR 50.59 evaluate.'on for carrying out the FSAR changes for seismic qualification of equipment at BFN, and (2) identify any actual change to the system or component outside the scope of USI A-46, or any replacements and new equipment items for the facility using the approach described in Paragraph C.6.3.3 of Appendix C to the Updated FSAR dated July 22, 1993.

TVA Res onse The introductory section of BFN FSAR Section C.6.3 st:ates in

part, "The current BFN optional equipment seismic qualification criteria for new items and replacements which are design changes are generally in accordance with NRC Regulatory Guide 1.100 (Reference 20) and IEEE 344-1975 (Reference 32).

This optional, current criteria is used for a majority of BFN design changes for Class I equipment.

This practice will continue until the A-46 Generic Implementation Procedure (GIP) methodology is included in a licensing basis revision."

Section C.6.3 of Amendment 10 of the BFN FSAR was prepared as a general revision to update the FSAR in light of the effort developed by TVA in the recovery of Unit 2. It was not TVA's intent to change the licensing basis of BFN to adopt the GIP methodologies as an exclusive method for the purpose of the development of design modifications for new and replacement electrical and mechanical equipment.

Rather it was TVA's int:ent to acknowledge the GIP-2 methodologies as an additional element to be considered when preparing design modifications for new and replacement items of safety related electrical and mechanical equipment.

It was recognized by TVA that GIP-2 methods include certain aspects that are not currently in the BFN licensing basis.

The FSAR revision was made with the intent that prior to performance of associated walkdowns, evaluations and subsequent NRC acceptance, any modifications to the plant would include the pertinent aspects of the GIP-2 to ensure that the equipment would successfully pass a future A-46 evaluation.

Consequently, Appendix C of the BFN FSAR was not revised to include GIP-2 methods for the sole and exclusive purpose for the design of new and replacement items of electrical and mechanical equipment.

TVA's intent is further emphasized by

41

the statement at the end of Section. C.6.3 that states "the objective is to assure that the required seismic adequacy is maintained or achieved so that it can be verified later by A-46 criteria in accordance. with References 24 and 25."

TVA has not made any modifications to safety related electrical and mechanical equipment solely on the basis of GlP-2 methodologies.
