UNIT 1 - RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION
Dear Mr. Denton:
On April 21, 1980, Mr. Steven A. Varga sent a circular letter to all Construction Permit and Operating License Applicants. In it, certain information regarding Category I masonry walls was requested.
The attachment to this letter responds to the NRC request for additional infou ation. Under separate cover, one set of the following full-sized drawings is being sent to Mr. I. A. Poltier, Project Manager: A-71, A-72, A-150 through A-161, A-183, A-188 through A-198, A-200, A-201, A-208 through A-211, A-231, and A-232.

, RESPONSE TO NRC INFORMATON REOUEST ON CATEGORY 'I CONCRETE PASONRY WALLS Informatic, Recuest No.1:
Are there any concrete masonry walls being used in any of the Category I struc-tures of your plant? If the answer is "No" to this question, there is no need to answer the following questions. .
Response: Yes, the Cincinnati Gas & Electric Company is using concrete masonry walls in Category I structures for Zimer Station. .
Information Recuest No. 2:
Indicate the loads and load combinations to which the walls were designed to resist. If load f actors other than one (1) have been employed, please indicate their magnitudes.
- Response: Masonry walls in Category I structures are being designed for loads and load combinations as given in the attached Table 1. These walls ,
are not subjected to other design loads such as wind, tornado, missile, pipe whip, and jet impingement loads.
Informaticn Reauest No. 3:
In addition to complying with the applicable requirements 'of the SRP Sec-tions 3.5, 3.7.and 3.8, is there any other code such as the " Uniform Building Code" or the " Building Code Requirements for Concrete Masonry Structures" (pro-posed by the American Concrete Institute) which was or is being used to guide the design of these walls? Please identify and discuss any exceptions or deviations from the SRP requirements or the aforementioned codes.
Response: Concrete masonry walls are being designed in accordance with the National Concrete Masonry Association " Specification for the Design and Constructior, of Load-8 earing Concrete Masonry," April 1974. No
. exception is being taken to this specification except that no over-
- stress factor is being used for OBE load combinaticn as against 1.33 recomended by the specification for such severe environmental loads as wind, earthquake, etc. For the abnormal / extreme environmental loading combinations involving SSE and LOCA loads, an overstress f actor of 1.67 is being used. These overstress f actors are consis-tent with the SRP guidelines for- safety-related structures. '
Information Reauest No. 4:
Indicate the trethod that you used to calculate the dynami'c forces in masonry walls due to earthquake, i.e., whether it is a code's method such as Uniform Building Coda, or a dynamic analysis. Identify the code and its effective date i if the code's method has been used. Indicate the input motion if a dynamic ,
analysis has been performed. ,
Response: Seismic lateral loads are being determined by an equivalent static method using the expression ws"9* W
~
f 9
. . \
where:
w, = seismic lateral load W =
weight of the masonry wall including any attachment load g =
seismic acceleraticn in the horizontal directicn obtamed frm the m+4n=4 floor response spectra curves. The ocm-bined curves being obtaired by adding the spectra frcm seismic, SRV and IfCA events.
The natural frequency of the walls is being detemin~9 usig stan-dard expressicns for single degree of freeds systems using the sec-
)
tion properties of the wall Maa9 on the r<vninal mascnry unit size.
'lhe response spectra curves are entered with this calculated value i of frequency to obtain the value of 'g' .
}i 1 Walls are assumed as simply supported or cantilevered beams, as applicable, for frequency calculations and for design and analysis.
Infernation Request No. 5:
How were the mascnry walls and the piping / equipment supports attached to them designed: Provide enough numerical exanples including details of reinforcement l and attachments to illustrate the methods and procedures used to analyze and i design the walls and the anchors needed for supporting piping /equignent (as 1 applicable).
I i
Fesponse: Mascnry walls in Category I structures are being used as non-load l MaHng walls and are not being included as part of shear wall system i for the Category I structures. These walls will only be relied upon as interior partition walls and will be separated frcm the flocr 1 abcVe by a gap.
No major piping or equipnent will be attached to the Category I mascnry walls, Ex pt for those liras shown on Table 4. At*ar+n=nts l which will be allowed include small bore piping, instrument lines, ccnduits, juncticn boxes, etc. These attachments will be made ,
either with expansion anchor or with through bolt plate assembly.
Attar +mant loads are being accounted for in the design by assuming j a concentrated mass at mid-span with a maximum eccentricity of 6 inches frm face of the wall. Magnitude of the rass on any 1-foot wide horizcntal strip of mascnry wall is 180 lbs.. for solid block walls, and 135 lbs. for grounted b1cck walls. Actual attachment loads will be field verified and a final check will be made to ensure the adequacy of the walls.
Masonry walls are being designed using working stress principles 4
with unfactored loads and are being analyzed based en conventicnal l elastic methods. Design is being made using the ncminal masonry I unit. Horizontal reinforcement is ignored in the flexural design of f the masonry walls, except for a few walls a re the reinforcement is l
censidered in the design. -l l
l 6
Allowable stresses used for the design are given in attached Table 2. Whenever expansion anchors will be used for attachment of piping, there is a minimum f actor of safety of 4.0 for SSE. Effect of the anchor plate flexibility is taken into account for the design of expansion anchors.
Expansion anchors which will be allowed to be used are either wedge or sleeve type anchors with their sizes varying from 1/4" diameter to 3/4" diameter and with a minimum embedment length equal to 4.5 times the disneter.
~
Masonry walls in Category I structures are being constructed as single or multi-wythe grouted or solid block walls with full mortar bedding of the units using running bond construction. No cavity wall -
construction will be allowed. Properties of the different materials ~.
used for masonry wall construction are given in attached Table 3.
Wythes will be bonded together by full mortar collar joints and by ladder type reinforcement which overlaps the adjacent wythes every second course. ,
Sample calculations for concrete masonry walls in Category I struc-tures for Zimmer Station are attached.
Information Recuest No. 6: ,
Provide plan and elevation views of the plant structures showing the location of all masonry walls for your f acility.
Response: The following is a list of drawings r,howing the plans, elevations and details of all the concrete masonry walls in Cate-gory I structures for Zimmer Station:

, 3. Eccentric Moment = By xe Different mortar surfaces, horizontal as well as vertical, at the location of attachment, have enough shearing resistance to resist the block-pulling effect from the loads mentioned above. The overall bending effect of load PH is considered assuming a 1 - foot horizontal strip acting as a beam between the supports. The attachment load is considered either as one concentrated load at mid-span or two concentrated loads, one at each quarter point of the span. Tensile stresses due to this bending are directly added to the tensile stresses fes calculated on Page 5.

III. WALL DESIGN 36" thick solid block wall is multi-wythe construction bonded together by full mortar collar joint and by continuous
.. truss bar reinforcement which overlaps the adjacent wythes every second course. As such, the section properties of 36" thick solid block wall are used for design. The design procedure is essentially the same as shown for 12" hollow block wall in Example No. 1 except for the section properties of 36" solid block wall which are as follows:
A = 2 427.5 in /ft
= 4 '
I 45213.0 in /ft
= 3 S 2538.3 in /ft wall weight Wg = 430.5 PSF of wali area for 140#/f t3 solid block wall Frequency calculations are based on the section properties of 36" solid concrete block wall.
