Dear Mr. Keppler:
DOCKET NOS. 50-266 AND 50-301 RESPONSE TO IE BULLETIN 80-11 MASONRY WALL DESIGN POINT BEACH NUCLEAR PLANT, UNITS 1 AND 2 This is to provide our initial response to IE Bulletin 80-11 dated May 8, 1980.
Enclosed herewith is the report entitled
" Interim Report On Masonry Wall Design" for Point Beach Nuclear Plant, Units 1 and 2.
This report provides information requested for the initial 60-day reporting period of the bulletin concerning masonry walls.
Based on a field inspection, we have identified fifty-two masonry walls or blockouts whose failure could affect safety related equipment.
These walls were originally designed accord-ing to Uniform Building Code criteria and not analyzed for specific FFDSAR loadings.
We intend to proceed with a program of either upgrading each wall to meet FFDSAR loading criteria, or to verify each wall's ability to meet required design loadings.
We have begun preparations for initiating the upgrading and verification work.
This effort, including any modifications that result from the analysis, will proceed as rapidly as possible.
We will advise you in detail of our progress in the 180-day response.
Very truly yours,

BULLETIN ITEM 1 (IDENTIFICATION OF SAFETY-RELATED MASONRY WALLS)
An inspection survey of Point Beach was conducted from June 16 through July 2, 1980 to identify safety-related walls.
Prior to the survey, inspection packages were prepared to provide the field inspectors with marked-up drawings showing safety-related components.
The survey was conducted in accordance with
" Field Walk-Down Procedure for Concrete Masonry Walls and Blockouts for Point Beach Nuclear Plant".
The procedure is attached to this report as Appendix A.
The survey included identification of the following classes of walls:
a.
Concrete block and brick walls b.
Masonry blockouts in concrete walls c.
Unreinforced concrete blockouts in concrete walls d.
Brick walls used as fire protection for building columns The survey results indicate that 52 walls were found to be safety-related masonry due to the proximity or attachment of safety-related equipment.
A summary of the safety-related 4
walls identified is as follows:
18 Concrete block walls in the Auxiliary and Control Buildings 28 Reinforced concrete walls with one or more blockouts filled with concrete blocks, bricks, or unreinforced concrete 4
Steel building columns with brick facing used for fire protection 2
Facade stairwell walls The blockouts listed above were openings left in the plant concrete walls for routing piping, conduit, and cable tray, or for moving large equipment into a cubicle.
These were then filled with masonry or unreinforced concrete.
A list of all safety-related walls is attached to this report as Appendix B.
Each wall is identified by a unique number and the approximate plant location, type of wall construction, attachments, and safety-related equipment in proximity are identified. !

BULLETIN ITEM 2A (EVALUATION PROGRAM)
The following is the prioritized list of safety-related walls that will be verified to meet FFDSAR loading criteria, or upgraded as required.
This is a partial list only and does not include all the walls.
First Priority Review all safety-related block walls or blockouts with external attachments greater than one hundred pounds.
The following walls are in this category:
19, 24, 39, and control room partitions Second Priority Review all unloaded unreinforced concrete block walls and blockouts.
The following walls are in this category:
3, 20, 22A, 26, 64, 68, 72, 86, 104, 128, 3-10, 5-5, and 5-29 Third Priority Review unloaded reinforced concrete block walls and blockouts.
The follow-ing walls are in this category:
40, 143, 151, and the facade stairwells
)
All walls which have been designated as reinforced or unreinforced were surveyed using a magnetic reinforcing f
locator.
Selected walls were " chipped out" to verify the reinforcing and this work is continuing.
The chipping procedure is described in Appendix A.
The above priority of wall evaluation is listed in order of the potentially weakest to the strongest walls.
The wall strength evaluation required by bulletin Item 2b will be based on chipping investigations in addition to construction drawings.
The priority list for investigation will be completed when the field inspection data are summarized and the chipping program finished.

BULLETIN ITEM 3 (JUSTIFICATION OF THE EVALUATION CRITERIA)
Justification for the review criteria will be submitted with the 180-day report (November 4, 198 0).
Justification will be based on the codes and established standards related to concrete and masonry design.
All FFDSAR loading criteria will be considered in the review.

, IDENTIFICATION OF REBAR AND ANCHORS M
Rebar finders shall be used to locate all vertical and horizontal rebar in the wall.
3.1 The diameter of the vertical rebar shall be determined by exposing at least one vertical rebar per wall.
3.2 The diameter of the horizontal rebar shall be determined by exposing a horizontal rebar in at least one horizontal bond beam per wall.
3.3 The type and diameter of floor anchors shall be deter-mined by exposing an area along the bottom of the wall that extends between two adjacent vertical rebar and is approximately 4 inches high.
3.4 The type and diameter of anchors along vertical edges of a blockwall shall be determined'by expdsing a 3 ft.
high by approximately 4 inches wide area along each edge of the wall.
3.5 Ceiling anchors are not expected-to exist,-however, an
=-
area along the top of at least four walls designated by the Team Leader shall be exposed and inspected for ceiling anchors.
The exposed area shall extend between-two adjacent vertical rebar and shall be approximately 4 inches high.
3.6 When anchorage is provided by dowels, the entire portion of.the dowel extending f.nto the blockwall shall be ex-
' posed so that its lengen can be recorded.
This shall lie done for at least cae dowel per wall.,
4.1 If the rebar/ anchor spacing is found to be equal to or les.s than than specified on the applicable civil or architectural drawing and if the rebar/ anchor dia-meter is equal to or greater than specified, then no further investigation of the reinforcement and. anchor-age of the wall need be performed.
r-n-
f the conditions of paragraph 4.1, above, are not metr vertical robar shall be exposed at 15 feet (maximum) intervals along the wall, horizontal rebar in each bond
(.
beam shall be exposed at 20 feet (maximum) intervals along L.C@F the wall, floor anchors shall be exposed at 20 feet (max-imum) intervals along the wall, and vertical edge anchors shall be exposed in one additional area.
p 4.3 P.ebar/ anchors may be exposed at additional locations at L.
the discretion of the Team Leader.
s-
, 5.1 Exposing rebar and anchors shall be done by chipping 4.
with chisels, impact tools or by coring with machines using masonry bits only.
5.2 All holes shall extend 1,or 2 inches past the rebar or anchor, but no more than 2 inches past the center of the yall.
5.3 Whenever possible, holes shall be staggered along the r
length of the wall.so that the holes do not align ver-ticall.y.
6.
The
$hcing and diameter of all exposed vertical and horrro tal rebar shall be recorded.
The spacing, dia-meter and a description of all exposed anchors shall be recorded.
The projection of exposed dowels into block-walls shall be recorded.
O REPAIR OF. HOLES IN BLOCKWALLS 5
7.
Holes in blockwalls sha'll be repaired by drypacking or s. --
by grouting.
Drypacking is recommended for.. deep holes. -
2-s and for locations where grout cannot be poured.
Grouting b
is recommended for shallow or large holes.
When rebar is exposed, grouting is preferred.
8.
All loose block, mortar and grout shall be removed from the hole prior to filling.
t 9.
Holes shall be prepared for filling by either of the following methods-1.
Holes to be prepared by this first method shall be keyed.
The hole shall then be soaked with water r
and packed with wet burlap at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> before a
filling.
Soak the hole again, just prior to filling, and remove all exc,ess water.
Coat the inside of the s
hole with neat.3 rout just prior to filling.
s 2.
Coat all surfaces in the hole with an epoxy resin t
concrete adhesive just prior to filling the hole.
M-25/6 j
i Application of the adhesive shall conform to the manufacturer's instructions.
Epoxy resin concrete b
adhesives shall be Epoxtite (2385, 2390 or 2393) manufactured by W. R. Grace & Co., Epibond manu-
'factured by Furane Plastics Inc., or an approved v
equal.

Holes shall be filled by either of the following methods:
1.
A drypack mixture consisting of'(by volume) 1 part portland cement to 2-1/2 parts of sand graded so that 100% will pass a No. 16 screen may be used.
Suffi-cient water shall be used to' produce a mortar that will stick together when molded into a ball by a slight pressure of the hands and will not exude water but will leave the hands damp.
The filling shall be of a consistency that is at the point of becoming rubbery when the material is solidly packed.
Dry-pack shall be packed in layers.
Each layer shall be solidly compacted over its entire surface using a hardwood stick and a hammer or a pneumatic hammer with a drypack head.

Grout shall be_ mixed in acco.rdance with..the_manufac _.
turers instructions.
Forms are required when nonshrink grout is used.
Typically, forms should be made of 1/2 or 3/4 inch plywood and should be held in place either by bracing from adjacent structures or by anchoring to the wall with ram-set powder driven nails.
A 2" high, wedge type opening should be lef t at the top of the form so that a pencil vibrator or a rod can be inserted into the hole to compact the grout.
About 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after grouting, the wedge shaped projection of grout at the top of the form should be removed.

Note: Safety-Related conduits were identified by either the conduit number or by the cables routed in the conduit. The conduit number in most cases is identified by the equipment it services.
(Ex:
Pump 2Pil - conduit 2PilAl; 1M0V850 - conduit ^l-850).
When a conduit number was not identifiable by the equipment it serviced, the conduit number was identi-fied in the raceway schedule (Dwg. E-33) which indi-cates cables routed in the conduit. These cables were then identified as safety-related or non-safety related. All unidentifiable conduits were considered to be safety - related. Piping systems were identified from the NRC Bulletin 79-14 Program.
