Units 1 and 2)

TESTIMONY OF PHILADELPHIA ELECTRIC COMPANY REGARDING THE ABILITY OF SAFETY RELATED STRUCTURES TO WITHSTAND THE EFFECTS OF POSTULATED DETONATION RESULTING FROM THE ASSUMED RUPTURES OF THE ARCO AND COLUMBIA GAS TRANSMISSION PIPELINES INTRODUCTION

1. On January 9, 1984, the Atomic Safety and Licensing Board (" Licensing Board") requested additional testimony from the parties regarding the ability of safety related structures at the Limerick Generating Station to withstand the effects of postulated detonations resulting from the assumed rupture of the ARCO and Columbia Gas Transmission pipelines. The Licensing 30ard expressed an interest both in the ability of the safety related structures to withstand such postulated blasts and the margins above such values inherent in building design. (TR 59 34-44 ) . This testimony is responsive to that req test and includes the following:

o A discussion of the various terms related to the analysis such that they can be understood and used consistently throughout.

o A description and results of the analysis regarding the ability of safety related structures to withstand pressures determined for the postulated accidents previously analyzed in testimony before the Licensing Board related to contentions V-3a and V-36.

I o A discussion of the TNT explosion on the Reading Railroad described in the Final Safety Analysis Report as indicative of the pressures to which certain safety related structures have been  :

designed. <

o A discussion of the margins above the calculated pressures for which the integrity of safety related structures can be assured.

o A discussion of the analysis used to demonstrate that a failure of the cooling towers resulting from a pipeline explosion would not affect safety I

related structures, components, or systems.

DEFINITIONS OF TERMS

2. Because there has been confusion regarding the terms associated with pressures resulting from detonations, the following are the definitions utilized in this testimony:

i

Incident Pressure is the sudden rise in pressure due to the violent release of energy from a detonation. The peak positive incident oressure (Pso) is the maximum incident pressure above the ambient pressure.

Reflected Pressure is the total pressure which results instantaneously at a _urface when a shock wave travelling in one medium strikes another medium, e.g.,

the ground.

Peak Positive Reflected Pressure (Pr) is the maximum reflected pressure developed above the ambient pressure.

PilYSICAL DESCRIPTION OF EXPLOSIVE PHONEMENA

3. In the design of structures to resist the effects of accidental explosions, the effect to be considered is the resulting pressure. This pressure is in the form of a shock wave composed of a high pressure shock front which expands outward from the center of the detonation with intensity of the pressure decaying with distance.

As the wave front impinges on a structure, a portion of the structure or the structure, as a whc le, will experience a structural loading as a result of the shock i

pressure. For the purpose of this report the terms explosion, blast and detonation are used interchangeably.

TYPES OF BLAST ENVIRONMENT

4. The types of detonation loading on the plant facilities can be identified as air-burst loads and surface-burst loads. The air-burst blast environment is produced by a detonation which occurs above the ground surf ace and at some distance away from the structure so that the initial shock wave, propagating away from the explosion, impinges on the ground surface prior to arrival at the structure. As the blast wave continues to propagate l outward, a front known as the Mach Front (Figure 1) is formed by the interaction of the incident wave and the reflected wave which is the result of the reinforcement of the incident wave by the ground.
5. The surface-burst blast environment is produced by a detonation which occurs at or very near the ground surface. The initial wave of the explosion is reflected and reinforced by the ground surface to produce a reflected wave. The reflected wave merges with the incident wave at the point of detonation to form a single wave, which is essentially hemispherical in shape (Figure 2). For a given distance and TNT equivalent l'

(Zg) a ground blast would give a greater pressure on the walls of a structure than an air burst blast. In this analysis of the ARCO and Columbia Gas pipeline i

explosions, a ground blast was assumed uniform over the wall height when the walls of structures were being analyzed and an air blast was assumed for analysis of the roofs.

BASIS OF ANALYSIS

6. This analysis of the structural integrity of safety related structures of the Limerick Generating Station utilizes as a basis the methodology discussed in the testimony of John Walsh. (Testimony of Jchn D. Walsh relating to contentions V-3a and V-3b) (Tr . f f 5411) .

That testimony developed the maximum pressure that would be developed at any of the safety related structures for the S tation. Such maximum pressure would result from a rupture at the closest approach of the of the Columbia Gas Transmission pipeline to such structures, i.e.,

approximately 3500 feet, leading to a postulated detonation approximately 1200 feet from the structure.

However, to analyze the effect on all safety related l structures, it must be recognized that the detonation l

could be assumed to occur at locations farther away than

! that assumed to give the maximum pressure, but which could produce more limiting pressure for particular structures, e.g., spray pond pump house. Therefore, utilizing the same methodology as used in the Walsh I _ _ - _ _ _ - - _

Testimony, the Columbia Gas Transmission pipeline explosion was assumed to occur along a line parallel to and 700 meters (approximately 2300 feet) from the pipeline (see Figure 3). Utilizing the distances from this line to safety related structures, the peak positive reflected pressure for each of the particular structures was determined.

7. It was not necessary to calculate the pressures resulting from the assumed rupture and detonation of gasoline from the ARCO pipeline inasmuch as the resulting pressure, assuming an explosion centroid along the Possum Hollow streambed, as did Walsh, is always significantly less than that resulting from the assumed detonation of the vapor from the Columbia Gas transmission pipeline as developed above. As calculated by Walsh, the maximum peak positive reflected pressure from an ARCO pipeline explosion is 1.9 psi.
8. For purpose of analysis two calculations were made for each safety related structure. The first calculation, done for the purpose of calculating roof loads, varied the assumed elevation of the detonation from roof height to 500 feet above the ground in order to find the maximum roof load. A second calculation was done for the purpose of calculating wall loads. It assumed a surface-burst blast to determine the peak positive

reflected pressure to be utilized for the analysis.

This pressure was then resolved and applied normally to 4

the wall in order to assess the structural capability of the critical portion of the wall.

1

9. As discussed above, various points along the line of the possible explosion, as indicated in Figure 3, were examined to determine the pressure applied normally on safety related structures. The pressures have negligible effects or; safety related buried pipes, manholes and ductbanks. The analysis of building wall response to the calculated peak positive reflected pressure was divided into two portions. Initially, local response of each structural element was examined.

By examining the structural drawings of each wall face, the critical element of that structural face could be determined based upon the peak positive reflected pressure as determined for such wall. Once that determination was made, the critical element was examined as if it were a beam element with appropriate end conditions representative of those for such element in the structure. Physical properties of the structures determined from design values such as location and amount of reinforcing steel and the minimum specified 28-day design concrete strength were used. Using the methodology of Reference 1, pages 6-1 through 6-13 and

6-21 through 6.23, shear and bsnding espacities were calculated for the critical locations and compared to the acceptance criteria presented in Reference 1 at page 6-48.

10. For the reactor enclosure and diesel generator building, inasmuch as the Reading Railroad accident analysis discussed below had already been performed, the normal pressures on critical locations from this event were compared to the assumed maximum value of 10 psi from the Columbia Gas Transmission pipeline explosion as calculated by Walsh. For these structures, the Reading Railroad explosion was found to bound the Columbia Gas Transmission pipeline explosion for the structure walls.

Inasmuch as the maximum pressure calculated by Walsh of 10 psi was not normal to the structure walls, this is conservative.

11. The second part of the analysis involved the global response of each structure. The loadings on the entire structure, i.e., story shear and overturning moment, were calculated and compared to the loadings resulting from the Safe Shutdown Earthquake (SSE). For each structure, the loading resulting from the SSE was found to be controlling.

RESPONSES OF STRUCTURES OF THE READING RAILROAD BLAST

12. One of the events which had previously been analyzed with regard to design of the Limerick Generating Station was the pressures resulting from the hypothetical explosion of TNT assumed to be carried on the Reading Railroad. The analysis considered a surface detonation and examined the effects on safety related structures of the facility. The structural analysis utilized the same methodology as described in the previous section relating to the analysis of the Columbia Gas Transmission pipeline explosion. The relationship of the Reading Railroad to the facility resulted in the maximum loads being applied to the walls of the structures and not to the roofs.

sum 1ARY OF RESULTS OF ANALYSIS

13. Table 1, Summary of Accidental Exolosion Pressures, presents the controlling peak positive reflected pressures for each safety related structure. Because of the postulated location and magnitude of the various l

explosions, i.e., the track of the railroad versus the l

locus of the centroid of the assumed Columbia Gas Transmission pipeline explosion, the controlling accident is dependent upon the magnitude of the blast, the distance to the structure and their orientation.

Inasmuch as the detonation resulting f rom the rupture of

the Columbia Gas pipeline was assumed, in the alternate scenario, to be elevated, the roof pressure was determined to be critical for this accident. One item should be noted. The peak calculated pressure resulting from the railroad car explosion is listed in Table 1 as 16.1 psi for the reactor building. This is the pressure experienced by the critical element of the wall rather than the average wall pressure which is approximately 12 psi.

MARGINS OF STRUCTURAL CAPABILITY

14. In order to respond to the Licensing Board's questions with regard to margin of structural capabilities of the safety related buildings, the maximum pressure that each structure could experience without exceeding the acceptance criteria in Reference 1 page 6-48 was calculated. For this analysis, in order to provide a realistic assessment of margin, the actual strength of the concrete as determ'ined from field measurements at 28 days was utilized, rather than the minimum specified 28 day design value. This analysis did not utilize the additional strength of concrete which is a result of strength gain resulting from the years of additional aging since the concrete was 28 days old. This l

l unaccounted for increase in strength is at least 20 i

l percent above the value utilized in the evaluation of

.= - . _. - -- . _-

1 I

margin and thus represents an additional conservatism.

The technique used to analyze the structural elements

. i was also conservative in that side support of the critical elements considered was neglected and redistribution of the imposed load was not assumed.

15. Even at the values contained in Table 1 for which the acceptance criteria of Reference 1 were just met, incipient failure of the structure is not implied, i .

There is additional margin to failure as a result of '

additional plastic deformation which would take place without failure. With regard to shear, the acceptance values utilized also have certain inherent margins.

16. The margins of the global building response to the
assumed detonation were also examined against the
loadings resulting from the Safe Shutdown Earthquake in order to quantify the margin inherent in the global response of the structure. It should be noted that there is additional margin in the safety related structures with respect to their ability to withstand the Safe Shutdown Earthquake above the values for which they may have been analyzed. The overturning moment and story shear due to the assumed detonation were developed for each structure. The total force against each j critical wall, as determined by the various pressures applied to it, was utilized in this evalution. The e

worst case for each structure e.g., the Reading Railroad or Columbia Gas Transmission pipeline accident, as appropriate, was utilized in determining the margin which was present. As may be seen from Table 1, margin exists at each location with regard to global building response.

COOLING TOWER ANALYSIS

17. Since the cooling towers are not in and of themselves safety-related structures, they are treated differently in that they are conservatively assumed to fail given the occurance of a pipeline explosion resulting from a postulated rupture of the Columbia Gas Transmission line as discussed in the Walsh testimony. Thus, the discussion of the effect of the failure is limited to the impact of the hypothetical failure upon safety related structures, systems and components. Figures 4, 5, 6 and 7 show the dimensions of the towers and their locations relative to other structures and componants at

! the Limerick Generating Station. Based upon observations of previous cooling tower failures, model tests and a comparison of the design of the Limerick cooling tower cooling towers to those which have experienced failures, the failure mode of the tower is expected to be by buckling. This failure mode results i

i

in the debris falling predominantly within the tower base area (372' tower base diameter), with a small amount falling on outside areas away from the tower. As a limit, all such pieces of concrete would be expected to fall within a target area with a radius equal to one tower base diameter measured from the center of the tower. This is based upon failures evident in Ferrybridge, Britian (Reference 2); Ardeer, Scotland (Reference 3) and the Grand Gulf plant at Gibson, Mississippi. Model tests by Der and Fidler (Reference

4) also substantiate the inward bending and buckling of the shell.
18. For analysis purposes it was conserva4ively postulated that the cooling tower failure would produce a piece of concrete about 5' x 5' x l' thick which would fall within a target area with a radius equal to one tower base diameter from the center of the tower (Reference 4, 6 and 7). The striking velocity of the piece of concrete at the ground is conservatively assumed to be 200 feet per second. This compares conservatively with the velocity of 188 feet per second for a free fall of approximately 550 feet from the top of the tower to l grade at El. 217 feet. The worst orientation, i.e., a l

l corner of the piece hitting the ground, was assumed, l

l

19. The size of the piece of concrete was selected because it is conservatively larger than pieces whict. might be generated as a result of consideration of the design of the structure including the size of the shell and its reinforcement. The analysis also considers the estimated buckling shape and wave length of the tower shell (Reference 4).
20. The assumed concrete piece is calculated to penetrate the soil approximately 2.8 feet using the same methodology as for penetration of tornado missiles. As shown on Figures 8 and 9, the minimum soil cover or equivalent protection for the seismic category I buried pipes and duct banks is 4 feet. Hence, the assumed cooling tower concrete piece is known not to affect these buried structures. The analysis further shows that the impact of the piece of concrete would not over stress the buried pipe or the concrete duct banks due to soil compression. Other category I items requiring protection from the assumed tower piece of concrete were examined. These include manholes for the duct banks. The top of these manholes are adequately protected from such missiles by steel and concrete covers. Other indirect f ailure modes, as a result of the failure of the cooling tower basin, have also been examined.

. 21. The cooling tower cold water basin walls have been designed as non-seismic Category I structures. They may fail under a safe shutdown earthquake tornado or blast.

The water from the tower basin could flow through a possible breach in the damaged basin walls and flood the surrounding area.

22. The runoff pattern of the water would be similar to that established for the intense storm precipitation (Figures 10 & 11). Most of the flood water from the cooling tower basin would run away from the power plant complex.

The worst-case flood conditions for the power plant complex would be created by a failure of the south side of the Unit 1 cooling tower basin wall. For this case, a portion of the cooling tower basin water would flow towards the turbine enclosure. Although some limited turbine enclosure flooding may occur, there would be no impact on safety related components. This scenerio was discussed in response to NRC Question 410.5 which is attached hereto and incorporated by reference.

23. While the differences in elevations between the cooling tower basins and the grade outside the power block I

buildings is approximately 41 ft, (Figure 6) the hydrostatic head on the seismic Category I manholes and duct banks would be relatively small compared to this difference in elevations based on the runoff pattern.

l l

l

[ l i

The access opsnings at the top of the manholes are protected from runoffs with tight-filling steel covers bolted to the adjacent concrete slabs. Water penetration would be minimal. -

24. All electrical cables in the duct banks (Figure 12) have been designed to function under water. In addition, all electrical conduits that travel to electrical manholes outside the structures are sealed watertight to prevent water from entering the structures through the electrical duct banks. This has been addressed previously in Section 3.4.1 of FSAR and responses to NRC i

Questions 410.2 and 410.6 which are attached hereto and incorporated by reference herein.

25. Most of the seismic Category I piping is supported on rock where erosion from short time water flooding would be insignificant. To the northwest of the Unit 1 cooling tower por tions of the seismic Category I buried pipes are supported on Type I , granular fili. However, most of the soil cover over this location is more than 10 ft., with a small portion having about 5 ft- of l cover. Since the water would run off rapidly on the i

l ground surface, it would take the least resistant flow path with very little penetration into the ground to cause erosion of the pipe bedding (Figure 13) . Some soil cover would be washed away, but it would take time 1

l' t

L. . .- _ ._ _ _ _ ._ .___ _ _ _ _ . _ _ _ - - - _ - - . . _ -.

to expose the pipes completely. The water flow for a large breach in the basin wall would last approximately 30 minutes. Furthermore, the adjacent seismic Category I piping could span more than 30 feet with no supporting material underneath and still carry the weight of pipe and contents without loss of function. A considerable time (much longer than 30 minutes) would be required to cause a large erosion of this size to undermine the supporting capability of the pipe bedding. The result I of this phenomenon is similar to, but less severe than, the failure of non-seismic Category I buried pipes as .

l addressed in response to NRC Question 410.47 which is 1

attached hereto and incorporated by reference herein.

1 Hence, it can be concluded that undermining of seismic Category I buried piping would not be a concern. I

26. Based on the above discussions it is concluded that the seismic Category I buildings, buried pipes, duct banks and manholes are suitably located and adequately protected against a conservatively postulated cooling rower failure resulting in missiles and water flooding.

They will perform their design functions safely without adverse consequences due to such an incident.

27. The foregoing presentation demonstrates both quantitatively and qualitatively that margin exists for loading of the safety related structures due to the blast resulting from the controlling event.

OUESTION 410.5 (Section 3.4.1)

For those non-seismic Category I vessels, pipes and tanks located outside of buildings, discuss the effect of failure of these items and any potential flooding of safety related structures, systems and components. Provide a similar discussion for non-tornado protected vessels, tanks and piping.

RESPONSE

The failure of non-seismic Category I and non-tornado protected tanks, vessels, and major pipes located outside buildings (Table 410.5-1) will not adversely affect safety-related structures, systems, and components as discussed below.

. Tank Failures The location of tanks in the yard area is shown in Figure 3.8-58.

Failure of the tanks en the west and south sides of the power plant complex (Table 410.5-1, items 1 through 5) will not cause potential flooding of safety-related structures, systems, and components. Any flooding'due to a failure of these tanks will be contained within seismic Category IIA earth dikes, which will remain stable under both static and dynamic conditions. The design of the earth dikes is discussed in the responses to Questions 240.4 and 241.14.

The tanks on the north side of the power plant complex (Table 410.5-1, items 6 through 9) do not have seismically designed containments around them. Failure of these tanks could cause local flooding. This flooding would not adversely affect safety-related facilities for the following reasons:

a. Surface drainage in this area will drain water towards the Schuylkill River and Possom Hollow Run before it can reach the power plant complex.
b. Seismic Category I electrical cable and duct banks located in the vicinity of these tanks are adequate, as discussed in the response to Question 410.6.

Even if the above dikes were to fail, there would be no i.Tpact on other safety-related structures, systems, or components due to site drainage.

Failure of Coolina Tower Basin Wa)1 (Table 410.5-1, items 10 &

11)

The failure of the cooling tewer basin wall would not adversely I

( ' affect safety-related structures, systems, and components as discussed below.

410.5-1 Rev. 23, 08/53

LGS FSAR

/

The runoff pattern of water from the cooling tower basin wall failure would be similar to tnat caused by intense storm precipitation as shown in Figures 2.4-4 and 2.4-5. Most of the flood water from the cooling' tower basin would run away from the pcwer plant complex. The worst-case flood conditions for the power plant complex would be created by a failure of the south side of the Unit 1 cooling tower basin wall. For this case, a portion of,the cooling tower basin water would flow towards the turbine enclosure. Although some limited turbine enclosure flooding may occur, there would be no impact on safety-related components.

The seismic Category I electrical cable and duct banks and valve pits located in the flow path of the water from the failed cooling tower basin are adequately protected as discussed in the response to Question 410.6.

Failure of Circulating Water Conduit (Table 410.5-1, item 12)

Failure of the conduit within the yard area between the cooling tower basin and the turbine enclosure will cause flooding of this area. Water from the damaged conduit will erode the soil cover and flood the yard.

The runoff patteri. will be similar to that shown in Figure 2.4-4.

The seismic Categery I electrical cable and duct banks and valve pits, located in this area are adequate, as discussed in the response to Question 410.6.

In the most severe case, all the water from the cooling tower basin could drain through the damaged conduit into the yard area between the cooling water pumphouse and turbine enclosure and cause flooding of the condenser pit. However, safety-related systems and components would not be damaged, as discussed in Section 10.4.1.3.3. See also the response to Question 410.92.

Failure of Maior Yard Piping Failure of any of the pipes identified in Table 410.5-1, items 13 through 17, may cause local flooding. However, the intensity and i volume of water discharge from any of the pipes is less than that of the cooling water conduit failure discussed above and would not cause damage to any safety-related facilities. Soil erosion caused by failure of these pipes is discussed in the response to Question 410.47.

Provide a discussion of the protection afforded safety-related systems and components, including underground cables, with respect to flooding or wetting caused by (1) groundwater, :21 design basis flood, '3) design basis precipitation or (4) failure of an outdoor tank or tank truck, RESPONSE .

Safety-related structures, systems, and components, including underground cables, will not be adversely affected by flooding or wetting caused by the items listed above.

The safety-related structures, systems, and components located within the yard area are shown in Figure 3.8-58. Excavation for seismic Category I structures, pipelines, electrical duct banks, manholes, and underground diesel oil storage tanks are shown in Figure 2.5-37.

Protection of structures against the intrusion of groundwater is discussed in the response to Question 410.8. Groundwater does not affect the yard facilities because the design groundwater elevation (Section 2.4.13.5) is generally below yard facilities.

The design basis flood is not applicable to structures and yard facilities. The design basis flood level with respect to the Schuylkill River is 207 ft (Section 2.4.2.2), which is 10 feet lower than the lowest grade level entrance to any of the safety-related facilities.

The protection of safety-related structures, systems, and components with respect to flooding caused by the design basis precipitation is discussed in Section 2.4.2.3. The runoff patterns for flood water caused by precipitation are shown in Figures 2.4-4 and 2.4-5. Below grade parts of structures are protected from water intrusion as stated in the response to Question 410.8.

The following seismic Category I yard facilities may be susceptible to flooding:

a. 5 Valve pits for RHR and ESW piping l
b. S Valve pits for diesel oil storage tanks l The valve pits may be temporarily covered with water during an intense s:orm or major failure of an outdoor tank. Hower, the 410.6-1 Rev. 17, 02/83 4

l following protective features have been provided ta resist resultant flooding of these-facilities:

a. They are built as reinforced concrete boxes and are equipped with solid steel manhole covers with gaskets,
b. The tops of slaos cf these facilities are elevated 3 to 12 inches above grade.
c. All, valve pits are equipped with drain pipes leading seepage water into normal waste drainage system.

All electrical cables are designed to operate under water. Water absorption characteristics for all cables have been reviewed to ~

confirm that even under flooded conditions, electrical cabling in manholes and duct banks will continue to operate properly. In

. addition, all electrical conduits that travel to electrical manholes,outside the structures are sealed to prevent water from entering.'the structures through the electrical duct banks (Taole 3.4-1)..,<

The design features described above will also protect seismic Category I structures and yard facilities against internal flooding in case of-failure of an outdoor tank or tank truck. -

The response to Question 410.5 gives additional discussion of flooding due to failure of outdoor tanks.

- LCS FSAR CUESTION 410.47 (Section 9.2.1)

Verify that the failure of one buried non seismic Category I pipe in a SSE will not result in failure of safety related buried pipes by soil erosion.

I RESPONSE The integrity of safety-related seismic Category I buried pipe will not be impaired through soil erosion by a failure of one buried non-seismic Category I pipe. This conclusion was based on the following conditions.

- - a. All but approximately 170 feet of common trench has been constructed in rock, where erosion of the supporting medium would be insignificant.

b. The 170 feet of trench not constructed in rock is in Type 1 fill.

The non-pressure pipes (gravity lines) in this section, such as the blowdown line and waste and storm lines, do not pose a significant erosion problem. The non-seismic Category I pressure lines in this section consist of a 36-inch Schuylkill River makeup water line and a 12-inch fire line (Figures 410.47-1 and 410.47-2).

Failure of the non-seismic Category I pressure pipe may create progressive erosion in the Type 1 fill. It is anticipated that water under pressure would pen'etrate to the surface, creating a progressively enlarging crater.

However, because the water will flow in the direction of least resistance, once the water penetrates to the surface, the crater will bc enlarged at a relatively slow pace. The span capacity needed to support the weight of the safety-related pipes in the trench is conservatively estimated to be in excess of 30 feet, based on the maximum allowable spans given in the ASME code. A considerably long time would be required to ,

erode a crater large enough to exceed this span capacity.

c. Instrumentation would give indication in the control room if a break occurred in the n:n-seismic Category I pressure pipe. Loss of flow from the makeup water line to the cooling tower would result in an alarm in the control rocr when low level is reached in the cooling

(

N tower casin. It is conservatively estimated that low level would be reached within 30 minutes.

410.47-1 Rev. 17, C 2,'S 3

LGS FSAR Low pressure in the 12-inch fire line, following a break, starts a fire pump that gives an alarm in the control room without a fire signal.

Following an SSE, if either alar = described above is activated, personnel will investigate fer evidence of a faulty condition in the pipelines described in (b) above

, and will initiate any necessary corrective action.

d. The procedures for operator response to a seismic event will include the requirement that, within two hours after an SSE, personnel will investigate for evidence of a faulty condition in the pipelines described in (b) above and will initiate any necessary corrective action.
