1 s Submittal of Information Requiced by IF Bulletin 80-11 Item 2.b.1 Refer to Reference (1), item 1 for the complete list of masonry walls in proximity to safety-related equipment. 1. Reactor Building, El. 303', Analog System Battery Rooms The new analog system batteries were recently installed via EDCR

79-2.

The double wythe block walls, shown in Figures 1 and 1A, act as a dividing partition between the two new battery rooms. The walls are constructed of two wythes of 6" thick, ASTM C-129 Type 1 blocks fully grouted. Mortar and grout comply with ASTM C-270 standards for Type-S mortar. Each wythe is independently reinforced both horizontally and vertically. Horizontal reinforcement consists of extra heavy weight "Dur-0-Wall" every second course. Vertical reinforcement consists of

4 deformed bars (Fy=60 ksi) with #4 dowels embedded eight inches into the slab.

Vertical rebar locations are noted on Figures 1 and 1A. 2. Control Building, Switchgear Room, El. 248' 1 The south wall of the switchgear room is constructed of eight inch thick, hollow concrete block. The wall separates the switchgear room from the ramp leading to the radwaste control room and also acts as a fire barrier. The wall varies from 8*-6" to 12'-6" in height and is solidly mortared to the bottom of the El. 262'-6", one foot thick concrete slab and to the east and west Control Building concrete f' walls. An elevation of the wall is shown in Figure 2. The wall is clear of supports except for a 4" diameter conduit. The wall is constructed of ASTM C-129, Type 1 blocks, Type S mortar and is reinforced with extra heavy weight "Dur-0-Wall" in every course. 3 Diesel Generator Rooms, West Wall The west wall of the Diesel Generator Rooms was designed to be I removable in order to facilitate equipment replacement. The wall is i constructed of removable steel columns acting as edge supports for 12" thick hollow concrete block in-fills. Figures 3 through 3B shows the configurations of these wall panels. The walls are essentially free of .f attachments except for the through-bolted lateral restraint plate for support SW-H-80 (Refer to Figure 3A). The walls are constructed of ASTM C-129, Type 1 blocks, Type S mortar and are reinforced with extra l heavy weight "Dur-0-Wall" in every other course. 4.& 6. Diesel Oil Day Tank Enclosure The Diesel Oil Day Tanks (TK-42-1A & TK-42-1B) are surrounded by (Wall j

4) and separated from (Wall #6) each other by 12" thick hollow concrete block walls.

The north wall of this enclosure is 13'-8" high and 17'-3" long. It is intersected by walls of equal height at each end and at mid-span. All four walls extend from a 91/2" concrete curb -l to a 6" thick concrete ceiling slab. The south wall of the enclosure 1 i

4 is reinforced concrete. The function of these walls is to act as a fire barrier, isolating the oil tanks from each other and from the rest of the ground floor turbine area. The walls are essentially free of attached equipment except for the lower end of two cable tray hangers which were attached to the north wall for lateral support. The walls are constructed of ASTM C-129, Typc 1 blocks, Type S mortar and are reinforced with extra heavy weight " Dor-0-Wall" in every course. 5 Control Building, El. 262'-6", Battery Rooms The battery rooms are separated from each other and from the cable vault area by the arrangement of block walls shown on drawing G-191153 The exterior walls are either 7'-4" or 8'-4" high and are mortared to the underside of the El. 272'-6" concrete support beams or to the underside of the El. 272'-6" slab. The interior partitions vary from 6'-2" to 7'-6" in height, span from east to west and are free at the top. Various electrical panels are mounted on or are attached to the exterior battery room walls and three battery racks are attached to two of the interior block walls as well as being bolted to the floor. All of the walls are constructed of 8" thick hollow concrete block, ASTM C-129 Type 1, Type S mortar and are reinforced with extra heavy weight "Dur-0-Wall" in every course. 7 Reactor Building, El. 213'-0", Block In-Fill in Northwest Corner Wall i After the required piping (two 8" diameter, two 1 1/2" diameter and a 1" diameter line) was routed through a construction opening left in the northwest corner wall separating the RCIC compartment from the general torus area, the wall opening was sealed with concrete shielding i blocks. The plugged opening measures 32" by 36" and is 3' thick. Concete shielding blocks, conforming to ASTM C-145, Grade "A", with a i minimum uniform density of 140 lbs. per cu. ft., were used. The blocks were laid with Type S mortar, are three wythes thick, to meet shielding requirements, and are unreinforced. 8. Reactor Building, El. 252', stairwell Enclosure The stairwell enclosure separates the stairs from the remainder of the Reactor Bailding and is constructed of 8" thick reinforced concrete i block. Figure 8 depicts a plan view of this area as well as the typical reinforcing called for on drawing G-191627 In addition to being a reparation barrier the wall panel shown in Figure 8A serves as [ a support for the CRD scram discharge volume tank and piping. l The vertical #4 reinforcing bars shown in Figure 8 meet ASTM A-15 and l i I A-305 requirement (yield =40 ksi) in accordance with Specification 5920-A-12 (see Attachment A). The blocks meet ASTM C-129 Type 1 and the mortar is Type S. 9 Reactor Building, El. 213', RCIC Area This is another example of concrete block being used to seal an opening j \\ I i . - ~ - - ~

in a concrete shielding wall. This opening is in the same general area as the in-fill discussed in the description of Wall #7 and its configuration is shown on Figures 9 and 9A. The types, strengths and materials are the same as those discussed for Wall #7 One difference between the two in-fills is that RCIC hanger H-90 is bolted through the in-fill. i 10. Reactor Building, El. 252', North Wall, RHR Valve Room The north wall of the RHR room has a 2' by 3' by 2' thick block in-fill similar to those discussed for Walls #7 and #9 Two 1" diameter lines, two 3/4t' diameter plugged lines and two 2 1/2" diameter plugged lines pass through the in-fill. The plugged lines mentioned above were incorrectly identified as equipment, through-bolts in Reference (a). The types, strengths and materials used in the construction of this in-fill are the same as those detailed for Wall #7 11. Regetor Building, El. 252', South Wall, RHR Room I The south wall of the RHR room has the concrete, shielding block i in-fill shown on Figure 11. It is constructed with Type S mortar and has extra heavy weight "Dur-0-Wall" joint reinforcement in every ot.her course. Its 2'-0" thickness is the same as that of the reinforced l concrete wall into which it is set. i a 12. Reactor Building, El. 280', Removable Block Shield Walls for Reactor ^ Water Cleanup Heat Exchangers and Pump Rooms The arrangement of walls shown on drawing #G-191628 provide radiation shielding for the clean up pumps and heat exchangers. If equipment should have to be replaced, the walls may be removed, thus providing increased access to facilitate equipment replacement. The walls are all 4'-0" thick and are constructed of concrete shielding block ( ASTM C-145, Grade A), Type S mortar; and have extra heavy weight "Dur-0-Wall" joint reinforcement in every other course. Walls labeled A, B, and C (see drawing G191628) are free at the top, while walls D and E are built into reinforced concrete walls. There are no substantial attachments to these walls. 13 Reactor Building, El. 280', Shield Walls Around Standby Gas Treatment System l Reference (1) incorrectly identified these walls as being constructed of concrete block. They are actually constructed of reinforced concre te. 14. Reactor Building, El. 303', Wall on East Side of Fuel Pool Cooling System An 8" thick, grouted block wall was constructed east of the Fuel Pool Cooling System to reduce radiation levels in that area. The wall is 8' l l l

high and approximately 65' long. It is free at the top and at its north end. The wall is essentially free of wall mounted attachments but does have the bottoms of two ceiling mounted cable tray supports embedded into its top course. The wall is unreinforced and historical records outlining the type of block, mortar and grout used in its construction could not be found. 15 Reactor Building, El. 303', East Wall of Cleanup Phase Separator Tank Room This wall is constructed of removable concrete shielding blocks and serves as a radiation barrier as well as a potential equipment access opening. The wall is 9'-0" high, 25'-3" long and 4'-0" thick. It is solidly mortared to reinforced concrete on all four sides and is partially supported 15'-0" from its south end by the new Analog System Battery Room wall (Wall #1). Five dead load supports for a 1" diameter line are bolted to the east side of the wall approximately 4' from its base and 5' apart. A 4" diameter line also rests on the southern most sup port. The wall is constructed of three wythes of solid concrete shielding blocks, Type S mortar and is reinforced with extra heavy weight "Dur-0-Wall" every second course. 16. Reactor Building, El. 303', Door Shields for Cleanup Phase Separator The entrance to the cleanup phase separator room is shielded by the 3' thick solid concrete, block door "L" shown in Figure 16. This door "L" is constructed of the same materials as Wall #15 In addition to this door "L", the three 8" thick walls shown in Figure 16A were recently added to provide shielding. These three wall panels were constructed of fully grouted, hollow block and are unreinforced. Records specifying the block, grout and mortar properties could not be located. 17 Reactor Building, El. 318', Stair Enclosure Near BBCCW Surge Tank and Standby Liquid Control System The south and east walls of of the El. 318' stair enclosure are within one wall height of the above mentioned safety systems. These two wall panels are both 22'-8" high and are 18'-2" and 9'-4" wide, respectively. The walls are essentially free of attached equipment except for a few small conduit. The wall is constructed similarly to the stairwell walls discussed l previously for Wall #8, i 18. Reactor Building, Lower Level, Various Pipe Hangers Bolted Through l Block In-Fills Once again because of the construction practices employed at Vermont ! t b

Yankee a construction' opening was left in a reinforced concrets wall to facilitate the routing of required piping. After the piping was installed the opening was plugged with concrete shielding blocks. Details of the five attached pipe supports identified in Reference (1) are provided below. RCIC Hanger H90: Details of the block in-fill to which H90 is attached were provided with the description of wall panel #9 CS-H-82 & CS-H-77: These two supports are attached or at least partially attached to the block in-fill shown in Figure 18. This in-fill is in the northeast corner wall separating the RHR Heat Exchanger room from the general torus area. The block in-fill was constructed of solid concrete shielding blocks and Type S mortar. RSW Hangers H211 & H219: These two supports are bolted through the in-fill shown on Figure 18A. This in-fill is located in the Reactor Building's west wall which separates the Reactor Building from the Turbine Building. The properties of the materials used in the construction of the in-fill are the same as those discussed previously. 19 Reactor Building, El. 303', Enclosure Near Containment Air Compressor The south wall of the stair enclosure is adjacent to the Containment Air Compressor and three bolted attachments actually support some of the compressor's 3/4" diameter tubing. The wall is 14'-8" high and 16'-4" wide and is constructed in the same manner as the two previously discussed stair enclosures (Wall #8 & 17). Two pipe supports, restraining 1 1/2" diameter and 31/2" diameter lines, are through bolted 16" from the walls west edge. It has been determined that the loss of the containment air compressor is not a problem. 20. Control Room, Blocked in Area of Old Viewing Windows The Control Room viewing windows were blocked in for security reasons. The configuration of the blocked in windows in the vicinity of the vital control panels is shown in Figure 20 and details of the block-in process together with the materials used are provided in Figure 20A. 21. HVAC Room, Walls Near Control Room HVAC Chillers Two block walls are in proximity to the Control Room HVAC chillers. l The first is the Turbine Buildings E-line wall between column lines 11 & 13 The wall is 16' high with the lower 10' being a double wythe wall and the top six feet being a single wythe of 8" thick block. The double wythe section consists of two 8" thick hollow concrete blocks, fully grouted, and a 2" thick center core (total thickness = 1'-6"). The top 6' single wythe section is located at the west edge of the double wythe wall and is solidly mortared to the bottom of the H&V roof support beam. The wall is supported at every column line by being inset between the column flanges (column spacing = 27'-6"). l

l 1 ) The second wall in p.*oximity to the chillers is the old instrument shop's south wall. This wall is 14' wide by 9'-4" high and is constructed of 8" thick hollow concrete block. The wall is supported at both ends by perpendicular block walls and is topped with the shops 4" thick concrete roof slab. Neither wall has any appreciable wall attachments. Both walls were constructed of ASTM C129, Type 1 blocks. Type S mortar and extra heavy weight "Dur-0-Wall" in every other course. The double wythe wall uses strips of metal lathe or 1/4" mesh galvanized hardware cloth placed every 24", in alternate courses with the "Dur-0-Wall", between the two wythes. 22. Diesel Generator Rooms, Fill-In Between The Two Diesel Generator Rooms A 3' high by 12' long opening in the 12" thick concrete wall which divides the two diesel generator rooms was plugged in a manner similar to that used to seal the Control Room's viewing windows (Wall #20). Figures 22 and 22A illustrate the in-fills configuration, and methods and materials of construction. 23 Reactor Building, Various Pipe Penetrations This general heading was covered specifically in the discussion of Wall Panels #7, 9, 11 and 18. 24. Reactor Building, El. 252', Loose Shielding Blocks These loose blocks have been relocated such that their possible collapse does not endanger any safety systems. 25 Reactor Building, El. 318', Walls Near Skimmer Pumps A concrete block radiation shield wall, 3' thick by 9'-4" high by approximately 10' long is located near each skimmer pump. They are free at the top and at one side. The wall is constructed similarly to the other shield walls discussed previously. It has been determined that the temporary loss of the skimmer pumps will not be a problem. Item 2.b.ii The construction practices employed in the construction of Vermont Yankee's block walls are discussed in detail in Ebasco Specification No. 5920-A-12, " Masonry" (Attachment A). These detailed instructions, coupled with our consultant's on-site engineering supervision, ensured block wall construction of high quality. l i

Item 2.b.iii.a In general each wall panel will be analyzed individually using working stress design. Analyzed loadings include dead, live, seismic inertia, seismic displacement, tornado pressure, and the effects of attached safety and non-safety class equipment. It is expected that the controlling load combination will be Dead + Live + SSE Inertia + SSE Displacement. The typical analytical procedure follows: a) Determine panel boundary conditions. b) Calculate panel's fundamental frequency, f. l c) Select the peak acceleration from the appropriate curve in the frequency range between f1 and fi /2 to account for uncertainties in block properties. ARS curves at the top and bottom of the wall with 2% damping will be studied and the larger value chosen. d) Increase selected acceleration by a 1.1 factor to account for the effects of higher modes. Computer studies of wall panels similar in geometry to those being re-evaluated show first mode cortributions of 99%; thus, an increase factor of 1.05 would be sufficient. We will use the 1.1 factor for added conservatism. e) Calculate stresses due to seismic inertia (SSE and 1/2 SSE or the maximum hypothetical and the design earthquakes as referenced in the FSAR.) f) Calculate stresses due to attached equipment (dead load and seismic inertia) and add them absolutely to those calculated in step (e). (For piping support reactions include thermal loads.) g) Calculate stresses due to seismic displacements and add them absolutely to those calculated in step (f). b) Compare total computed stresses with the allowable stresses in Table 1 for reinforced masonry and with the allowables in Table 2 for unreinforced masonry. The allowables for normal loads (S), which includes loadings due to the design earthquake (1/2 SSE), are taken from the ACI 531-79 code. ACI 531-79, " Building Code Requirements for Concrete Masonry Structures," is a widely used, and highly respected code, nationwide. Its values of allowable stress are substantiated by testing done by the ACI and the NCMA (National 1._ __

Concrete Masonry Association). In general, the ACI allowable stresses have factors or safety of 3 to 4 over the applicable test results. Considering the abnormal sever.4ty of the maximum hypothetical earthquake (SSE) or the design tornado, these factors of safety can be reasonably reduced. After studying many of the test reports which form the basis of the ACI code allowables, increases in allowable stress ranging from 2.0 (compression and bearing) to 15 (shear) appear reasonable and consistent with previous FSAR commitments (Section 12.2.1). This increase in allowables will be used for re-evaluation purposes only. Any new walls or wall modifications will be designed to the ACI code.

1) If computed stresses are less than those listed in Tables 1 and 2, verify boundary assumptions and accept the wall as-is.

j) If computed stress is greater than the allowables, determine if any technical specifications are affected, design and install required modifications to bring the panel within ACI allowables. Due to mortar's relative weakness in tension perpendicular to the bed joint, the combination of SSE inertia and displacement often results in mid-span cracking for those walls whose aspect ratio result in their spanning vertically. When safety-related equipment is endangered only by the collapse of these cracked walls, a more detailed investigation of the effect of this cracking will be undertaken. Based upon tests conducted by Gabrielson, Kaplan and Wilton (References 3, 4, and 5), it has been shown that confined wall panels exhibit a great degree of additional capacity and stability after initial cracking. This additional strength is due to the shallow arch action illustrated in Figures A and B. In order for the wall to collapse out of plane, when confinement is provided top and bottom, either a shear or compression failure must occur in conjunction with the initiating tensile cracks. The full scale test program described in References c - e confirmed that confined block and brick walls did indeed undergo arch action and withstood pressure loadings as high as 19 psi, equivalent to about 34 g. These walls cracked in flexure but did not fail, and then withstood many cycles of reverse loadings with maximum equivalent to accelerations greater than 1 g. Considering these test results along with the field evidence cited by the authors, it was decided to use the rigid arching analysis where the boundaries were appropriate. Peak bearing pressure on the face of the block will be limited to the values listed in Tables 1 and 2. Arch action will not be used for walls which are not vertically confined or for walls with gaps at the top. Item 2.b.iii.b The few major equipment loadings, loadings greater than 100 pounds, were applied to the block walls by the use of through bolts and backing plates. The potential for block pullout and/or local shear failure will be investigated and stresses will be kept within the allowables listed in Tables 1 and 2. All the attachements to the wall will be analyzed to verify their adequacy. ;

Since the ACI code (or any other code) does not address collar joint a Stress, we selected the 8 psi value shown in Table 2 as being a conservative value to use until more testing is done on the subject. This allowable stress was increased to 12 psi for abnormal loadings. The wall ties identified in the specification will provide added insurance of the adequacy of the collar joints.
