- j. PAGE 4 0F 15 Discussion:
The issues relate to a concern that class 1E and non-class 1E ,
batteries are unacceptably supported since they have no vertical tie downs and the strut (Unistrut) used in their racks is -
unacceptable. ,
NRC General Design Criterion 2 requires Category I structures. l systems, and components to be designed to withstand the effects of ,
natural phenomena such as earthquakes. Sequoyah commitment to- ;
comply with this criterion is stated in SNP FSAR Section 3.1. The j seismic design bases of Category I items are described in FSAR ,
Sections 2.5 and 3.7. Specific application of these bases for Category I battery racks in class 1E service is contained in FSAR l Section 3.10, Design Criteria SQN-DC-V-11.2 and SQN-0C-11.2.1, and ,
. Specification 1591 for the vital battery system. .
e Class 1E electrical service is provided for those systems which are j essential to the safe shutdown of the power plant or to maintaining ;
radiation limits within NRC prescribed limits at the site ;
jl f boundary. For non-class IE services, it is not appropriate from l either a safety or an economic viewpoint to apply the more severe j
("Q 5 seismic design criteria which is used for class 1E services. Thus i i non-class 1E batteries need not have vertical tie downs to accommodate seismic events, and the strut used in their racks is i acceptable. l
. Table 3.2.1-3 of Sequoyah FSAR indicates that class 1E service [
. batteries are used for the 125 V vital battery system and the 125 V l diesel generator battery system.

) 1. Vital Batteries I to IV:
The batteries and racks are supplied by Gould, Inc.
under contract 73C8-83800. They are located at i elevation 749 feet of the auxiliary building as shown ,
f on drawing 45N230, RIS for vital battery rooms !
J through IV. The batteries and racks were ordered under the requirements of Specification 1591 ( App. A 6.d).
? Section D2 of this specification states the :
requirements for the seismic design of class IE
, equipment. Seismic qualification testing was performed by TI! Testing Laboratories under contract to Gould,
- Inc. as documented in ETL Re rt No. 5547 (App. A, 5.j; 05/20/74). The selsric qual fication tests were 0553D - December 31, 1986

This test report was approved by TVA as documented by TVA meno from Domer to Chandler (App. A, 5.k; 06/26/74). In addition, a seismic qualification analysis was performed by Gould, Inc. as documented in summary of calculations of 4-60 Cells NCX-2100 rack and !
S07-074698-666 (App. A, 5.1). TVA approval of the seismic qualification analysis was documented by TVA letter to Gould Inc. from Sprouse to Frenzel ( App. A, 5.y; 02/16/73).
i The following points are noted for the above referenced
' reports in conjunction with Gould, Inc. drawing 059469C (App. A, 5.f):
l o No positive battery tie down to the support rack was provided in the qualifying shake table tests.
! o The top strut side rail is clearly above the battery center of gravity, thus preventing battery tipping ,
during a seismic event.
o Strut (Unistrut) members were used in both the rack seismic qualifying analysis and the battery seismic qualifying tests.
l o The rack attachment to the shake table used a bolted connection (see later discussion in this report).
l i o Both test rack and contract rack shown on Gould, Inc.
i drawings 059469C (App. A 5.f) and 0590680 ( App. A,
) 5.c), respectively, indicate torquing bolted i + 2.5 foot pounds. Such torque ,
connections requirementsto are 27.5, for The internal rack assembly.
l The above provides evidence that the Gould, Inc. batteries i and racks for vital battery rooms I to IV were subjected to a i detailed seismic qualification program which demonstrated the acceptability of the use of strut (Unistrut) esterial and the 4
non-inclusion of battery vertical tie downs. '
3 The 125 Y vital battery system was also included by the NRC in their seismic audit of TVA equipment in late September l, 1976 ( App. A, 5.h). The NRC seismic team had requested that TVA provide the vital battery seismic test report to verify l ,. that tests were conducted without constraints to vertical motions. The NRC concluded that the batteries functioned 05530 - December 31, 1986

acceptably during and after seismic testing, according to infonnation submitted by TVA. This conclusion was reflected '
in Sections 3.10 and 7.8 of the Safety Evaluation Report .
(SER).
During the course of investigating this employee concern in January 1986 ( App. A, 5.s), TVA NSRS visually inspected the l' battery racks and identified a limited number (two to five) of improperly installed Unistrut fasteners in each vital battery room. Approximately 50 percent of the Unistrut fasteners were observed. NSRS recommended that SQN inspect ,
all Unistrut fasteners on the vital batteries for proper l installation and rework all improperly installed fasteners.
Sequoyah Engineering Project (SQEP) inspected the vital i battery racks with respect to this recommendation as indicated in a meno from Abercrombie to Seiberling
( App. A 5.t; 04/18/86). The SQEP inspection results '
revealed that several bolting installations of Unistrut fasteners in each battery room did not meet design requirements. SQEP performed calculations and showed that the as-built installation of the( App.
battery) racks
. was adequate
(? to meet design requirements A, 5.u NSRS investigators also found no quality assurance records to indicate that the bolt torque requirements in the vital !
battery racks had been verified by inspection. Therefore, I they recommended that SQN inspect a sample of Unistrut bolts t on each battery rack for proper torque if construction
' inspection records could not be located. In response to this NSRS recommendation, SQN indicated that 10 percent of the Unistrut fasteners for each vital battery rack would be ,
inspected for ) roper torque and the sampling size would be I increased if tw results of the initial sampling were i unacceptable ( App. A, 5.t). SQN commitment tracking report. l commitment verification and completion. form, tracking No. 86110 ( . A, 5.v) indicated SQN construction had inspected be t torque of the battery racks and retorqued all bolts of the racks for vital battery rooms I to IV to verify and record the prescribed torque value.
TVA NSRS concluded that no vertical restraint of the vital batteries was required by their seismic qualification.
Further, the battery racks were tested using Unistrut material and had been seismically qualified.

- REVISION NtMBER: 0 PAGE 7 0F 15 In March 1985, TVA received a letter from Gould, Inc.
(App. A, 5.w) regarding the need to limit the space between the end battery cell and the end stringer of the battery rack to 1/4-inch or less to maintain the battery's seismic qualification based on testing. Gould, Inc.-indicated the excessive space can be corrected either by moving the end stringer in or by placing a spacer between the stringers and the batteries. Subsequently, SQN issued ECN L6436 ( App. A, 5.x) to modify the battery rack assembly to eliminate the excessive space which existed at the end of each row. ~As.
indicated later in this report, these modifications have been completed.
- 11. Fifth Vital Battery:
The fifth vital battery and rack are located at elevation 749 feet of the auxiliary building as shown on drawing 45W299, R4 of vital battery room V. Both SQN and WBN fifth vital batteries are of the same design and were supplied by Gould, 'Inc. under contract 84X8-832101. The battery and rack were qualified to
(. the enveloping WBN and SQN response spectra. The seismic test report and qualification analysis were included in the Environmental Qualification Report by GNB Batteries, Inc. -( App. A, 5.1; 05/29/84). The cover page of the environmental report was marked with a TVA ,
approval stamp dated 11/01/85. ;
,! l Testing and analysis of the fifth vital battery and I
. rack were based on no vertical holdoown and the use of Unistrut for horizontal side rails. The battery racks
- shown on Gould, Inc. drawings 410334C ( App. A, 5.d) and 4 410336C (App. A, 5.e) were similar to the racks i supporting vital batteries I to IV.
The records in SQN Workplan 11188 ( App. A, 5.p) indicated that all bolted connections for the fifth vital battery rack were inspected for proper torque.
l iii. Evaluation Team Walkdown of Vital Battery System:-
I The evaluation team perfomed a plant walkdown on September 20, 1 986 to make a general comparison of the battery installation with the installation drawings and 3 seismic qualifications.

[ PAGE 8 0F 15 o All battery rooms appeared complete and in accordance with the installation drawings and seismic qualifications with exceptions noted below. The Gould, Inc. batteries were installed with no vertical battery tie downs.
Separation material was installed between individual batteries. The strut side rails were in place. The fifth vital battery rack was bolted to the base.
o The racks in vital battery rooms I and II were welded to the base embedded plate. The test rack in the qualification. report was bolted to the shake table.
Since both the test rack and the contract rack were analytically determined rigid by Gould, Inc. (App. A, 5.cc), the use of welded connection is technically acceptable. The rack anchoring detail shown on section B-B of drawing 47N230, R15 indicated welding to base embedded plate without specifying weld type, size, and length. The as-built rack was composed of six transverse frames and three longitudinal frames interconnecting the transverse frames with X-braces. The bottom of each transverse frame consisted of two steel angles (2-1/2 inches x 2-1/2 inches x 3/8 inch). Each angle was about 20 inches long and welded to the base embedded plate continuously on both sides of the angle along the longitudinal axis. The weld appeared to be 1/8-inch fillet weld or larger. Gould, Inc. installation drawing 059068D ( App. A, 5.c) showed two 9/16-inch-diameter anchor bolt holes in each angle. This inferred the use of two 1/2-inch-diameter anchor bolts since the test rack was also bolted to the shake table with 1/2-inch-diameter bolts. Upon comparison of the estimated allowable capacity between the welded and bolted connections, the evaluation team considered the as-built welding connection adequate and an acceptable alternate for the 1/2-inch-diameter anchor bolts.
B. 125 V Diesel Generator Battery System (CSD)
The original batteries and racks for the main diesel generator building installed pre-1980 had been replaced beginning in 1981 with the currently existing batteries and racks which are supplied by CSD Battery Division of Eltra Corp. under TVA contract 80K8-327334. The batteries and racks are located at elevation 722 feet of the diesel generator building - one set in each of four rooms as shown
.. on drawing 15N210, R5 and on elevation 723.2 feet of the
, additional diesel generator building as shown on drawing 7

C&D Report No. VL7610-02 ( App. A, 5.n; 11/18/76). TVA e7 proval of seismic qualification is documented by CEB memo from Barnett to Chandler (App. A, 5.m; 09/09/60) and TVA letter to C&D from Chandler to Walker (App. A, 5.aa; q' 09/24/80).
The following points are noted for the above referenced i reports:
o Positive battery tie down to the support rack was provided.in the qualifying shake table tests. 4 o The strut side rail is above the battery center of gravity, thus preventing battery tipping during a seismic event.
o Strut- (Unistrut) members were used in seismic qualifying
- tests.
o The rack attachment to the shake table used a bolted connection.
The above provides evidence that the C&D batterie's and racks for the four diesel battery' rooms in the main diesel generator building were subjected to a detailed seismic qualification program which demonstrated the acceptability of the use of strut (Unistrut) material. These batteries included ' vertical battery tie downs.
The records in SQN Workplan 9119, R1 ( App. A, 5.o) indicated that all bolted connections for the battery rack in the four battery rooms of the main diesel generator building were inspected for proper torque. -
During the course of investigating this employee concern in January 1986 (App. A, 5.s), TVA NSRS reviewed the seismic -
reports of the diesel generator batteries and racks, and visually inspected the as-built battery rack assembly installation. The inspection revealed holddown brackets were Installed on these batteries in accordance with seismic qualification. NSRS concluded that the batteries were rdequately installed with vertical restraint. Further, the battery racks were tested using Unistrut material and had been .

PAGE 10 0F 15 The evaluation team performed a plant walkdown on September 20, 1986 to make a general comparison of the battery installation with the installation' drawings-(CSD drawing M-7739, Rev. 5) and seismic qualifications. The specific areas included as a sample were the diesel generator building at elevation 722 feet,125 V i
diesel generator battery rooms 1A-A and 2A-A. Both battery rooms appeared complete and in accordance with the installation drawings and seismic qualifications.s The CSD batteries were installed with vertical battery tie downs. Separation material was installed between individual batteries; the racks were bolted to the base; and the strut side rails were in place.
The evaluation team reviewed the attachments to the two NRC letters from Youngblood to White ( App. A, 5 4 and. 5.r) for
. material applicable to this element report. The team found no l additional relevant issues or infomation other than those
! already inauded in the concern statement itself.
Findings:
l 4 The alphabetic identifiers listed below correspond to the list of-
\g issues in Section 1.
e a. Class 1E batteries are acceptably supported with or without l use of tie downs as required by seismic qualifications;
- non-class 1E batteries are. acceptably supported.
i
- b. The struts (Unistrut) used in the battery racks supporting the class 1E batteries are adequately qualified by testing and analysis; the struts used in the non-class 1E battery racks are also acceptable.
f
Conclusions:
I
- a. The issue that class 1E and non-class 1E batteries are unacceptably supported since they have no tie downs is not valid.
- b. The issue that Uni .st supports are unacceptably used is not
, valid.
- c. The employee concern for Sequoyah is not valid and does not require any further action.
