Q.3.
Please describe your involvement with these issues.
A.3.
The Structural Analysis Division of the Department of Nuclear Energy, Brookhaven National Laboratory (BNL), was reques,ted by the NRC Staff to review various design issues related to the Waterford foundation base mat and to provida its conclusions as to tha adequacy and structural integrity of ti.e base mat.
BNL's efforts were* directed by Dr. Morris Reich and received technical assistance from Drs. Costan-tino and Miller, whose services were provided under contract to BNL. The other sambers of the 8NL team were A.J. Philippacopoulos. 5. K. Sharma and P. C. Wang; the professional qualifications of these individuals are ettached to this affidavit as Attachment 1.
Our involvement with these issues commenced in March 1944 anc has continued to the present.. During this period, we met and consulted with men:bers of the hRC Staff on numerous occasions; reviewed s'everal re-ports prepared by the App 1tcant's consultant, !!arstead Engineering Assoc-tates, Inc.; met with and obtained further information from the Applicant and its architect-engineer, E8ASC0; and visually examined the cracks and water seepage. On July 18, 1984, we issued a report which provided a detailed description of"our analyses and conclusions concerning the
' Waterford foundation base mat, entitled " Review of Waterford !!! Basemat 1

Assessed the seismic qualification and safety of various mechanical e and structural components of. nuclear power plants under postulated earthquake, loads. The General Tirk & Rubber Company, Akron, OH .(1979-1980) Group Leader Senior Research Engineer (1977-1979) Initiated a comprehensive research program to study the mechanics of e tires and other automotive products made of rubbers and rubber-cord c omposites. Developed a nonlinear finite element computer code with several special features (incompressible element, contact algorithm, . composite material model, out-of-plane shear e ement, de fornation-l dependent pressure loads) that allowed modeling of the large-deforma-The code tion onalysis problems encountered in the tire industry. has been used extensively by many engir.eers in this company as a de-sign and analysis tool to expedite the product design process. 8 Conducted finite elenent studies on rubber-cord composites to deter-mine interply shear strains and stresses, out-of-plane rotation under uniaxial loading, and edge ef fects. Verified the theoret'ical results by experiments with specially design fixtures.

{ t t i l + ADDENDUM TO REVIEW OF WATERFORD III BASEMAT ANALYSIS Structural Analysis Division Department of Nuclear Energy Brookhaven National Laboratory Upton, NY 11973 August 3, 1984 l i l
_,J' .s ' Addendum to ' REVIEW OF WATERFORD III BASEMAT ANALYSIS 4 i t i Introduction Recently, ultrasonic methods were used to perform nondestructive tests on the Waterford III basemat with the objective of defining the extent of cracking in the basemat. These tests were perfonned by Muenow & Associates, Inc. On July-31, 1984, BNL personnel visited the Waterford site with the intent of visually observing the cracks, discussing the methodology used for the nondestructive tests, and to review the results obtained by Muenow & Associates to date. Visual Inspection of Cracks The major basemat cracks shown in Fig. 2 of the BNL report dated July 18, 1984 entitled, " Review of the Waterford III Basemat Analysis", were inspected. The basemat crack patterns appear to agree with the crack map of Fig. 2 of the BNL report and no significant extensions or ad-ditions of these cracks were observed. The observed cracks are closed at this time and no observable water seepage through the cracks was noted. The cracks along the sidewall and shield wall were also inspected. These cracks were all small and mostly of a type nonna11y associated
? i - 2'- i with thermal and shrinkage effects. Leachate was noted from many of these cra'tks. The leachate from the shield wall is most probably k associated with rain water accumulated in the annulus between the steel containment and shield wall during the construction phase, before placement of the dome section. Leachate from the sidewalls is most probably associated with water accumulated during construction. All sidewall and shield wall cracks were restricted to about the lower twenty feet of the walls above the basemat and are usually within the first pour of concrete. They are associated with relative shrinkage and thernal effects occuring between the basemat and the sidewalls. The visual inspection of these cracks supports the conclusion previously given in the BNL report that they do not present a structural safety issue. Results of Ultrasonic Testing Program At the time of the inspection, the ultrasonic program conducted by Muenow & Associates had essentially been completed for those basemat cracks outside of the shield wall. Investigation of basemat cracks under the RCB was still being conducted, while the investigation of the side wall cracks had not as yet been undertaken. Mr. R. Muenow present-ed his interpretation of the results obtained to date as well as a detailed description of his procedures.
.L For the visible,basemat cracks, the procedures employed by Muenow & Associates essentially measure time of arrival of a wave reflected off a ( t discontinuity in the concrete. This wave is generated by a small spring loaded hammer applying an impact to the surface of the basemat. For a single impact, a transducer located near the hammer is focused in a restricted (but known) direction, and measures the arrival time. 4 Knowledge of the arrival time and focusing direction leads to the determination of the location of the discontinuity. In addition, by restricting the viewing time of the sensor, only the reflection from the discontinuity being mapped is recorded. From a series of impacts at different locations, the extent (both length, depth and orientation) of the crack can be obtained. It is our opinion that this approach applied to the visible basemat cracks will give reasonable infonnation as to the length, depth and orientation of the cracks. It should be noted that the procedures used are based upon recording and viewing only the relatively low frequency content of the reflected waves. Therefore, any discontinuity smaller than 10 to 20 inches cannot be observed in this study; cracks of this small size are not structural-ly significant for a 12' thick base mat and need not be evaluated as a part of the NDT program. (This cutoff frequency can be controlled by the operator to pick up smaller discontinuities, if desired). Therefore, reflections from single reinforcing bars do not interfere with the crack measurements. However, the layers of closely spaced rebars in the bottom of the slab result in a measurable reflection.
-a. + Data at these depths are judged to be less reliable, since it would be difficul,to differentiate between the reflections from the steel layers and reflections from the crack. Based upon Mr. Muenow's presentation, the following characteristics of the basemat cracks were noted: (a) All of the cracks were vertical. (b) The E-W cracks exterior to the shield wall ran from the shield wall to the side walls. The depths of these cracks varied in an un-dulating manner from several feet (2' to 4') to as much as 9 to 10 feet in certain locations. (c) Based upon preliminary data, Mr. Muenow located three primary E-W cracks under the RCB. Two of these appear to connect to the E-W cracks exterior to the shield wall. The specific depth contours of these cracks were not available at the time of our site visit, but indications ar1 that they may be similar to those in (b) above. l l (d) Cracks emanating in a radial direction from the shield wall are not as deep nor as continuous as the E-W cracks. (e) All of the basemat cracks are tightly closed. This observation is based upon the measured characteristics of the reflected signal.
Interpretation of NDT Results i I. 1 As statediin the July 18, 1984 BNL report, the basemat cracks were most likely causad by bending moments due to dead loads developed during the construction phase, which resulted in tensile stresses at the top of the slab. These moments would enhance previously existing small and unob-servable cracks due to normal themal and shrinkage effects, causing them to grow in width, length and depth. This conclusion was based upon the observation that some of the computed bending moments (shown in Table 1) are large enough to cause flexural cracking at the top of the slab. While the depths of some of the cracks measured by Muenow & Associates seem to be rather large (in fact they are deeper than BNL originally anticipated, before we completed our analyses), they can nevertheless be explained with the aid of Table 2 given in the BNL report. This table gives the strength characteristics of the slab in tems of the top reinforcement. The ratio of steel to concrete area for the top of the mat is very small (approximately 0.2%). Because of this reinforcement ratio the cracking moment for the slab is about 1640 Kips-ft/ft while the steel yield moment is about 1360 Kips-ft/ft. The consequences of the above moments in terms of crack behavior when the top of the mat is in tension can be explained in terms of the load sharing occurring between the concrete and the top reinforcement steel.
j , j j d e It should be realized that the steel carries little load until the I k concrete tracks. Thus, for example, when the concrete,at the upper - surfaceofthematreachesthemodulusofrupture'(i.e.,475 psi)andis at the verge of cracking, the top reinforcing steel is stressed to only -3600 psi. Once the concrete cracks, however, all. of the tensile load carried by the concrete is transferred to.the steel, which because of s the light reinforcement ratio immediately reaches its yield stress of ~ 60,000 psi. Because of equilibrium requirements, some of the applied moment will be transferred to adjacent sections adding to the lateral (as well as the depthwise) extension of the Oracks. Since such a failure is rather abrupt, one would expect the cracks to propagate to deeper depths than would normally be the case if the crack developed more gradually. Flexural cracks in concrete members normally extend through the tension zone to a level close to the location of the neutral axis (the neutral axis defines the region where the bending stress changes from tension to compression). It should be noted that the neutral axis for the basemat is located approximately 18 inches above the bottom of the mat for / bending moments which produce tension in the top of the slab. (The / depthofthecompressionzoneisgivenbyd(-pn+f(pn) + 2 pn) where p is the reinforcement ratio, n is the ratio of Young's Modulus of the steel to the concrete and d is the distance from the steel reinforcing bars to the bottom of the slab). Therefore, one would expect bending cracks to run rather deeply into the slab.
a- -7. The cracking'that has been observed does not affect the safety of the I L Waterf6rd facility, for the following reasons. Reinfor,ced concrete i. flexural members loaded in bending, such as the Waterford base mat, typically have cracks in the bending tensile stress region; generally, such cracked sections can safely carry bending moments and the presence of the cracks does not degrade the strength of the section. This is true becuase a flexural member resists a bending moment by developing internal tensile and compressive forces which develop a resisting couple (moment) equal to the applied moment. The reinforcement provides the tensile force and is clearly not affected by the cracked concrete. The compressive force in the concrete is not affected by the crack since a compressive stress can be transmitted across a crack. Furthennore, the presence of bending cracks does not affect the shear carrying capacity of the section (this is in fact the basis of the ACI Code provisions for shear), since interlocking between sections still occurs, and the cracks are not associated with diagonal tension failure. As pointed out in Appendix C of the BNL report, the sidewall soil / water pressures produce compressive stresses in the slab. In fact, it is the / action of these pressures which has caused the E-W cracks to close. It is shown in Appendix C that as a result of the side wall pressures, the l stress across the basemat is primarily compressive under static soil pressure, as well as under north to south and south to north SSE plus soil pressure loading with rather small tensile stresses occurring at the bottom of the mat. Even if the E-W cracks propagated through the
e e 8-d mat, the. crack would have no effect on the ability of the concrete to I I carry the applied compressive stresses. In effect, the side wall soil i. loads act as prestressing which closes the cracks that developed during construction. The BNL report concluded that the basemat was adequate and suggested that certain confirmatory analyses be perfonned. For the reasons, stated above, this conclusion is still considered to be valid. e i ,_,,!}}
