i l 2.6 Section VI discusses the evaluation of selected mechanical equip-ment, electrical equipment, and instrumentation. All of the equipment listed in Attachment 1 to the Staff's January 30, 1979 letter has been addressed. The data sheet for the emergency diesel generator will be submitted in a supplement to this report after the vendor completes a reevaluation. As discussed in Sec-tion VI, Paragraph 4.2.7, we anticipate that the reevaluation I will verify the conclusion that there is adequate margin when subjected to a 0.20g SSE. 2.7 Section VII discusses the conclusions drawn from the reevalu-ation.

3. Summary 3.1 The results of the reevaluation, which are discussed more fully throughout this report show that, even utilizing an SSE with an acceleration of 0.20g, the systems required to accomplish safe shutdown and continued shutdown heat removal will be able to function as designed. Furthermore, these results are themselves quite conservative, as discussed in the conclusions of Section 1 VII. This demonstrates that the Davis-Besse, Unit 1 design is acceptable in the event of a 0.20g SSE.

VI. EVALUATION OF MECHANICAL EQUIPMENT, ELECTRICAL EQUIPMENT, AND INSTRUMENTATION

1. Introduction 1.1 Various components have been selected for evaluation which are representative of mechanical, electrical, and control systems components required for shutdown. The components selected were those listed in Attachment 1 of the NRC Staff guidance trans-mittal of January 30, 1979. These components have either been evaluated or are in the process of being evaluated to provide a high degree of assurance that safe shutdown and continued heat removal can be accomplished after an SSE of 0.20g acceleration.

As discussed in Section I, the completed reevaluation of the I emergency desel generator will be included in a supplement to this report.

1. 2 Table VI-1 lists the components selected for evaluation and summarizes the pertinent information for each component. It includes the location of the component, the figure number (figure to be found in Section II) giving the appropriate response spectra for that location, the method of qualification for the component, and the data sheet number where more detailed seismic qualification information is provided. The data shaets are included in this section. They follow the format of Attachment 2 of the NRC letter. A brief discussion of the qualification of the selected equipment follows.

2. Electrical Components (Table VI-1 Items 13-18 and 20-21) 2.1 All safety related electrical equipment has been qualified either by test or analysis on the basis of the appropriate floor response spectra generated by the 0.15g SSE. Reference to Table VI-1 indicates the method of qualification.

2.2 The revised floor response spectra have been used to determine the margin available for the 0.20g acceleration SSE. 2.3 For the components which were qualified for the 0.15g SSE by testing, the test method was either sine beat or sine dwell, with highly conservative input levels. In some cases, equipment was subjected to as many as 75 sine beat tests and to sine dwells as long as 45 seconds. Based on the high input levels and the conservative nature of sine beat and sine dwell testing at resonance and integer frequencies, it is concluded that the margin for each component is sufficient to qualify it to the revised seismic requirements. VI-1 Supplement 1

2.3.1 As an example of the above, the 5 KV metal clad switchgear (Item 13 of Table VI-1) is discussed here. In this case, damping was first determined using sine sweep and the relation ( =h Where & = damping (percent of critical damping) Q = amplification

Quasi-retonance magnification curves were used to compare floor response spectra curves to maximum equipment buildup at resonance. The amplification was determined to be 5.5 times tne peak value of the sire beat input acceleration. The required test input was de-terminud to be 0.21g. However, the actual test input excitation was 0.3g, approximately four (4) times the required level. The rsvised floor response spectra, based on the 0.20g zero period atcaleration (ZPA) SSE using 3 percent damping, normalized to 5 p.ircent damping (consistent with the component damping), indicates a peak floor response at the equipment mounting location of 2.16g in the peak range of 5-7 hertz. The required test input is deter-mined to be 0.39g. Since the actual test input was 0.8g, the re-quired input for the 0.20g SSE is exceeded by a factor of two (2). 2.3.2 The other components which were qualified by sine beat or sine dwell testing were evaluated for margin, and in all cases, there was sufficient margin to qualify the components for the revised (0.20g) SSE requirements. 2.4 Items 16 and 18 of Table VI-1 were qualified by analysis. Their respective data sheets indicate the stresses calc'ilated for the 0.15g SSE on the critical structural elements. The seismic factor (defined in Section IV, Paragraph 1.1) is also calculated for these components. 2.4.1 The seismic factor for the critical structural elements of the unit substation transformers are quita large, indicating a large available stress reserve. Obviously, the transformers would function under the imposition of a 0.20g SSE. 2.4.2 The seismic factor for the critical elem its of the battery racks for the 0.15g SSE are not as high, but still provide margin for a higher SSE. To ensure that these critical elements would not be overstressed due to a 0.20g SSE, the stresses and the seismic factor for such an SSE have been calculated and are reported below: VI-2 l

assume seismic stress is total stress 2.4.3 In the cases noted above where qualification was demonstrated by analysis, it is concluded that stresses were below the allow-ables for both the 0.15g and 0.20g SSE cases. Therefore, there is sufficient margin to qualify the components for the revised (0.20g) SSE requirements. j

3. Control Panels and Instruments (Table VI-1 Item 19) 3.1 The auxiliary shutdown panel was evaluated as representative of a control panel with instrumer.ts required for shutdown. The panel was qualified by analysis, while the instruments were qualified by testing, for the 0.15g SSE.

3.2 The revised floor resp 2nse spectra have been used to determine the acceptability of the installation for the 0.20g SSE. 3.3 The data sheet for the panel indicates the stresses calculated on the side of the panel and on the anchor bolts. The seismic factor (defined in Section IV, paragraph 1.1) is also calculated. To ensure that the panel would withstand the loads due to a 0 20g SSE, the stresses and seismic factors for such an SSE have been calculated and are reported below: VI-3

(a) (b) (c) (c) - (b) Identification Seismic Total Stress (a) Stress Stress Allowable Panel 780 psi 780 psi 1610 psi 1.1 Anchor Bolts 9 ksi 9 ksi 20 ksi 1.2 The maximum deflection is calculated to be 0.0049 inch. This will not adsersely affect functional operability. The natural frequencies of vibration are greater than 33 Hz for the . structural system and various panel sections including the instrument package panels. Dynamic amplification of the flat spectra response of seismic acceleration is found to be a maximum of 0.87g in the structural system in the horizontal direction and 0.47g in the vertical direction. Use of these amplified dynamic loads as well as static loads with both horizontal and vertical effects show the bending, tensile and shear stresses in the various structural members and connections to be much lower than the maximum allowable stresses. Stresses in the anchor bolts are quite low and load capacity in the welds are quite high. Displacements in the instrument package panel sections are quite small and will not cause loss of function of the equipment. Loading of the panel plate sections and panel frz.me has been found to be much less than that required for buckling. The analysis methods used subjected the structural elements to more critical conditions than would be encountered by the structural system in a prototype environ-ment. It is concluded that the panel is structurally adequate to function properly when subjected to loadings associated with a 0.20g SSE. 3.4 The seismic test reports for the instruments mounted on the auxiliary shutdown panel have been reviewed. The data sheets summarize the pertinent information. The qualification testing envelops the revised response spectra, ensuring that the in-stroents will be operable for the 0.20g SSE. j 4.0 Mechanical Components (Table VI-1 Items 1-12 and 21-24) 4.1 Mechanical components required to accomplish safe hot shutdown after a seismic event and continued shutdown heat removal were originally qualified by analysis on the basis of the appropriate floor response spectra generated by a 0.15g SSE. A review and/or reanalysis has been performed for Items 1-12 and 21-24 to determine the margins available for a 0.020g acceleration SSE. In some cases, 1 the original seismic analysis (0.15g SSE) used acceleration values which envelope the acceleration values generated by a 0.20g SSE floor response spectra. In these cases, a reanalysis was not re-quired. In most cases, however, a new seismic analysis was per-formed on the basis of the appropriate floor response spectra generated by a 0.20g SSE. The mechanical components are listed - in Table VI-1, Items 1-12 and Items 21-24. VI-4 Supplement 1

4.2 A summary of the reanalysis for each of the mechanical components listed in Table VI-1 is described below. Items 21, 22, 23, and 24 were added to the Table by Toledo Edison after a review of the equipment required to accomplish safe hot shutdown after a seis-mic event and continued shutdown heat removal. 4.2.1 Auxiliary Feedwater Pumps The original seismic analysis performed by the p"mp vendor (Byron Jackson) showed that the equipment is qualified for a 0.15g SSE. Byron Jackson revised their original seismic analysis to incorpo-rate the required accelerations for a 0.20g SSE. This revised analysis showed the equipment had adequate margins when subjected to a 0.20g SSE. See Data Sheet 1. All stresses and deflections were within the allowable values. 4.2.2 Component Cooling Water Heat Exchangers The original seismic analysis performed by the vendor (Structhers Wells) showed that the equipment is qualified for the 0.15g SSE. The vendor performed a new seismic analysis incorporating the required accelerations for a 0.20g SSE. The new analysis used current state-of-the-art techniques for modeling the heat ex-changer and resulted in the determination of lower natural frequencies. These lower natural frequencies and the current i state-of-the-art modeling techniques resulted in the analysis showing insufficient margin for the anchor bolts and the base of the fixed support. The original analysis was then reviewsd using the ctrrent ana-lytical techniques. This review indhated that for 0.15g SSE the anchor bolts and base of the fixed srpport did not meet their original design margin. Therefore, it was decided to modify the saddle supports during the spring 1980 refueling outage to meet their original design margins for a 0.15g SSE. These modifica-tions also provide margin when the heat exchanger is subjected to a 0.20g SSE. It should be emphasized that this modification was made due to a change in analytical methodology and not inadequate margin for a 0.20g SSE. The calculated stress values shown in Data Sheet 2 reflect the modified saddle supports. 4.2.3 Diesel Fuel Oil Day Tanks The vendor (Richmond Engineering Company) revised the original seismic analysis to incorporate the required accelerations for a 0.20g SSE. The new analysis showed that the expansion anchors did not have a factor of safety of at least 4.0 in accordance with the bolt manufacturer's recommendation. A review of the as-built anchoring condition for the tank revealed that the anchor bolts did not have a factor of safety of 4.0 for a 0.15g SSE. However, the installed factor of safety was greater than 2.0. Modifications to the tank saddle supports are presently being made during the Spring 1980 refueling outage so that the VI-5 Supplement 1

installed factor of safety will be greater than 4.0 for a 0.1Fg SSE. This will also provide adequate margin for a 0.20g SSE. It should be emphasized that these modifications were necessitated by as-built conditions and not an increase in SSE accelerations from 0.15g to 0.20g. The vendor's new seismic analysis for a 0.20g SSE shows that the circumferential bending stress at the horn of the saddle is greater than the allowable stress. Based on a review of the conservatisms in the code and the ven-dors conservative analytical techniques, we believe that there is still sufficient margin in the design against failure. 4.2.4 Service Water Pumps and Motors The original seismic analysis performed by the pump vendor (Goulds Pumps) showed that the equipment is qualified for a 0.15g SSE. Goulds Pump revised their original seismic analysis to incorpo-rate the required accelerations for a 0.20g SSE. This revised analysis showed the equipment had adequate margins when subjected to a 0.20g SSE. See Data Sheet 4. The original seismic analysis which was done for the motors used seismic accelerations which are higher than the accelerations required by either a 0.15g SSE or a 0.20g SSE. The seismic 6;celerations used for the motor analysis are shown on Data Sheet. 4. All stresses and deflections for the pumps and motors were within the allowable values. 4.2.5 Auxiliary Feedwater Pump Turbine 1 The original seismic analysis which was done for the auxiliary feedwater pump turbine used seismic accelerations which are higher than the accelerations required by either a 0.15g SSE of a 0.20g SSE. The seismic accelerations used for the analysis are shown on Data Sheet 5. All stresses and deflectior.s were within the allowable values. 4.2.6 Borated Water Storage Tank The seismic loads for a 0.20g SSE were calculated by Bechtel Power Corporation. These calculations showed that the loads for a 0.20g SSE are lower than the seismic loads used for the origi-nal tank design based on a 0.15g SSE. Stress checks indicate that all stresses calculated for a 0.20g SSE were well below allowable values. Reference Data Sheet 6. 4.2.7 Emergency Diesel and Generator The original seismic analysis performed by the vendor (Bruce GM Diesel,'now Power Systems) showed that this equipment is qualified for a 0.15g SSE. The vendor is presently in the process of pre-paring a new seismic analysis report incorporating the required VI-6 Supplement 1

accelerations for a 0.20g SSE. The preliminary results of the new analysis will be completed by June 6, 1980 and will be reported by June 12, 1980. The equipment supplier, Power Systems, has stated that, based on 0.15g SSE analysis, the margins for all items analyzed were high and that a significantly higher seismic load could be carried before exceeding allowable stresses. Therefore, we anticipate that the new seismic analysis will verify the equipment to have adequate margin to withstand a 0.20g SSE. 4.2.8 Emergency Diesel Cooling Water Heat Exchanger This equipment is included in the analysis of the emergency diesel and generator. Refer to Paragraph 4.2.7. 4.2.9 Decay Heat Removal Cooler The origina! seismic analysis performed by the equipment supplier (Atlas, a supplier to Babcock and Wilcox) showed that the coolers are qualified for a 0.15g SSE. Babcock and Wilcox evaluated the new seismic response curves to determine the applicable loads for a 0.20g SSE. The new loads were considerably less than those used by Atlas in the design of the coolers. Therafore, the coolers have sufficient margin to withstand a 0.2Vg SSE. Refer to Data Sheet 9. 4.2.10 Decay Heat Removal Pump ar 1 Motor The original seismic analysis performed by the vendor (B&W) sh ved that the equipment is qualified for a 0.15g SSE. B&W reevaluated the critical structural components based on the peak I accelerations of the applicable 0.20g SSE response spectra, and showed that all stresses for the pump and motor were within allowable values. Refer to Data Sheet 10. 4.2.11 Decay Heat Removal Suction Valves HV-OH11 and HV-DH12 and Motor Operators The original seismic analysis which was done for these valves and motor operators used seismic accclerations which are higher than the accelerations acting on the valves during either a 0.15g SSE , or a 0.20g SSE. The accelerations used in the seismic analysis are shown on Data Sheet 11. All stresses were within allowable values. 4.2.12 Auxiliary Feedwater Pump Steam Inlet Valve MS-106 The original seismic analysis which was done for this valve and motor operator used seismic accelerations which are higher than the accelerations acting on the valve during either a 0.15g SSE or a 02.0g SSE. The accelerations used in the seismic analysis are shown on Data Sheet 12. All stresses were within allowable values. VI-7 Supplement 1

4.2.13 Component Cooling Water Pumps and Motors The original seismic analysis performed by the pump vendor (Goulds Pumps) showed that the equiptrent is qualified for a 0.15g SSE. The vendor performed a new seismic analysis to incorporate the required accelerations for a 0.20g SSE. The new analysis showed the equipment had adequate margins when subjected to a 0.20g SSE. See Data Sheet 21. The original seismic analysis which was done for the motors used seismic accelerations which are a higher than the accelerations required by either a 0.15g SSE or a 0.20g SSE. The seismic accelerations used for the motor analysis are shown on Data Sheet 21. All stresses and deflections for the pumps and motors were within the allowable values. 4.2.14 Component Cooling Water Surge Tank The original seismic analysis performed by the tank vendor (Brown-Minneapolis) showed that the equipment is qualified for a 0.15g SSE. A new seismic analysis was done by Bechtel Power Corpora-tion to incorporate the required accelerations for a 0.20g SSE. All stresses and deflections for the tank were within the allow-able values. Refer to Data Sheet 22. 4.2.15 Diesel Fuel Oil Storage Tank The original seismic analysis performed by the tank vendor (Rich-mond Engineering Company) showed that the equipment is qualified for a 0.15g SSE. The vendor reanalyzed the equipment based on the 0.20g SSE response spectra, and the reanalysis showed no 1 appreciable difference (0.26 percent increase) in seismic accelera-tion response of the vessel from that used in the original anal-ysis. Therefore, it is concluded that the vessels have adequate margins to withstand a 0.20g SSE. See Data Sheet 23. 4.2.16 Diesel Fuel Oil Storage Tank Transfer Pumps and Motors The original seismic analysis which was done for this equipment used seismic accelerations which are higher than the accelera-tions required by either a 0.15g SSE or a 0.20g SSE. All stresses and deflections were within tne allowable values. The analysis used accelerations of 1.2g horizontal and 0.8g vertical, and considered the horizontal and vertical loads to act simulta-neously. The peak acceleration values applicable for these pumps are 0.75g horizontal and 0.72g vertical as shown in Figure II-1 and II-2 (using 3 percent damping per Table II-1). A Data Sheet has not been included for these components because additional data from the equipment supplier is not available. VI-8 Supplement 1

5.0 Summary ; ) 5.1 The components selected and evaluated have been shown to have sufficient margin to perform their function when subjected to an 0.20g SSE. Modifications are being made to two mechanical com-ponents, component cooling water heat exchangers and diesel fuel 1 oil day tanks. However, these modifications are not a result of an increase in SSE acceleration from 0.15g to 0.20g, but are the result of reevaluating the 0.15g analysis in light of current

analytical techniques and as-built field conditions. When these
modifications are complete these components will have sufficient margin to withstand a 0.20g SSE.

VII. CONCLUSIONS

1. The previous sections of this report present the results of an intensive evaluation of the adequacy of systems required to accomplish safe shutdown of the reactor and continued shutdown heat removal in the event of an SSE with an acceleration of 0.20g.

2. This evaluation included an assessment of components, selected by the NRC Staff, representative of those necessary to achieve shutdown. It also included all stress problems for those piping systems required for shutdown. Further, it included randomly selected piping supports and ventilation ductwork supports.

3. In all cases, adequate margin was demonstrated such that the accomplishment of safe shutdown and continued shutdown heat I removal is assured.

4. The factors of safety presented in this evaluation have addi-tional inherent margins built-in as a result of either con-servative analytical approaches or the use of allowable stresses (code or allowable) which have within themselves additional factors of safety. Examples of these inherent margins are dis-cussed below for piping systems and piping and ventilation duct-work supports.

4.1 Piping Systems. Section IV, Paragraph 1.5 discusses how using a scale factor results in conservative seismic and total stress values. To show the conservatism of this approach three sets of stress cases were rerun using the complete computer reanalysis. These are:

a. Stress cases where the margin factor was not computed since by using the scale factor method it was obvious that an overstressed condition would result (i.e. margin factor

               >1.0) (31 of 50 cases).

b. Stress cases where the margin factor was computed using the i scale factor method but exceeded the allowable stress for the revised response spectra (9 of 50 cases).

c. Stress cases where the margin factor computed by the scale factor method was between 0.9 and 1.0 (10 of 50 cases).

Table VII-1 shows the results of the comparisons for all fifty stress cases reviewed. For this evaluation, the average margin factors showed approximately a 50 percent reduction after computer reanalysis. On an average basis this indicates that the scale factor method of analysis has an inherent factor of safety of ; two. j 4.2 Piping and Ventilation Supports. These are discussed in Sec-tion IV, Paragraph 2.0, and Section V, Paragraph 2.0, respectively. The margin factor or interaction values for the most stressed VII-1 Supplement 1

                                                                     %e members (the latter being reported for anchor bolts) are con-servative. For structural steel the allowable stresses were based on th AISC code which has built-in safety factors since they vary between 45 percent to 75 percent of the steel's yield stress, depending upon various parameters defining the con-figuration of structure and types of loads applied.

For standard catalog (non-engineered) items, i.e., pipe saddles, clamps, clevis, etc. , the manufacturer's allowable capacity is based on a minimum factor of safety of five compared to the ultimate strength. For engineered components, i.e., sway struts, snubbers, etc., the applied loads are based upon a faulted loading condition while the manufacturer's allowable is based upon the normal loading codition. This also provides an additional factor 1 of safety. In the case of anchor bolts, the manufacturer's allowables are one-fourth or one-fifth of the ultimate strength. The twelve pipe supports identified in Table IV-5 were reanalyzed considering the above additional conservatisms to determine a revised margin or interaction value. This reanalysis has shown that considering these conservatisms results in a reduction of the margin factor or interaction value by 22 percent to 80 percent. Of the twelve problems reanalyzed the reduction for eight of them fell in the 75 percent to 80 percent range. l l VII-2 Supplement 1 l l l i
