1.0 INTRODUCTION

This report presents the seismic stability evaluation of the cask transporter at the Diablo Canyon Power Plant (DCPP).

The HI-TRAC transfer cask loaded with an MPC exits the Fuel Handling Building (FHB) on a cask transport frame in a horizontal orientation. The DCPP Transporter lifts the HI-TRAC and the frame and moves along the road to the Cask Transfer Facility and then the Independent Spent Fuel Storage Installation (ISFSI), in the process descending a 8.5% nominal grade and then climbing a 6% nominal grade. At the CTF upending site, the transporter is used to rotate the HI TRAC cask to a vertical orientation. The transporter then moves the HI-TRAC to the CTF where the loaded MPC canister is transferred to a waiting HI-STORM storage cask. During the MPC transfer operation, four restraints are attached to the top of the HI-TRAC and to connections at the top of the CTF concrete structure to prevent overturning of the HI-TRAC/HI-ISTORM stack.

Also, there are four restraints attached to the transporter and to connections at the top of the CTF concrete structure to prevent sliding of the transporter. After the MPC transfer operation is executed, the transporter carries the loaded HI-STORM up a 5% nominal grade in a vertical orientation to its final position on the ISFSI pad for storage.

A design basis seismic event can occur during the various operations of the DCPP Transporter.

The seismic stability analyses in this report demonstrate that the transporter, while moving together with the carried casks, does not overturn, and does not leave the roadway by sliding.

Calculations to demonstrate the adequacy oftransporter seismic restraints to prevent excessive relative motion of the HI-TRAC at the CTF are not included herein.

2.0 METHODOLOGY AND ACCEPTANCE CRITERIA 2.1 Methodology Five design basis seismic events containing low frequency content have been specified for evaluating transporter stability on various loading paths for the Diablo Canyon ISFSI.

The QA validated computer code "VisualNastran 4D" [5.10] serves as the simulation engine to obtain the response to the 3-D seismic events. The program includes a dynamics algorithm that provides automatic collision and contact handling, including detection, response, coefficient of restitution, and friction. The ability to implement custom contact models to simulate complex non-linear behavior is also a feature of the code. The numerical integration is performed using the Kutta-Merson integrator with variable time-step. The interaction between two rigid bodies is modeled through a finite number of contact points named facets. The program automatically simulates impact, contact, lift-off, and sliding between bodies. These effects can be simulated using classical impulse-momentum relations where the user supplies a coefficient of restitution and a coefficient of friction for each potential set of contacting surfaces, or by using a more complex set of contact springs to represent the details of the contact stiffness. In this more detailed representation, at any contact point, a compression-only spring and damper is automatically located and activated between the two contacting bodies at every location where contact is indicated from the results at the previous time step. The spring rate and damping constant are user defined for every facet point; the computer algorithm automatically tracks all potential contact locations, computes the penetration and penetration rate and determines the instantaneous normal force at the location. The net lateral force at the contact point is limited by the instantaneous force multiplied by the coefficient of friction (assumed constant throughout the simulation). The following sketch demonstrates the custom contact model at a particular point where contact occurs involving Point 'TP" on Body 1 and Point "Q" on Body 2.

Body 1 7

u.

P Body 2 The associated damper, in parallel with the compression spring, is omitted in the sketch. When the facet point P is computed to have contacted Body 2 at location Q, subsequent penetration is computed and the spring compressed. The contact force at that location continues to act until the motion of the two bodies is such that separation occurs. Two components of horizontal force (not shown in the sketch) develop at the point of contact with the net horizontal force limited by the product of the instantaneous normal force and the friction coefficient. The accuracy of the contact algorithm is user specified. Once separation is indicated, no force is generated in eitl~r the compression spring or the associated damper until such time as the simulation again predicts that contact occurs at that location. For the simulations encompassed in this report, the impulse momentum contact algorithm is used for the scenarios that involve primarily sliding on an incliined roadway; for the analyses on a level roadway that are attuned to evaluating the propensity for tipover, appropriate local contact springs are defined to represent the transporter tread interface with the roadway.

The motion of the rigid body model is defined by three translations (displacements) of the origin of the body coordinate system and three rotations. Assuming that the rigid bodies are of uniform mass density, the program automatically determines the mass center location and mass moments of inertia based on the geometry and the mass.

The time-domain dynamic simulations model the Transporter, the rI-STORM overpack, the HI TRAC 125 transfer cask, the MPC, and the cask lids as rigid bodies. The lids are rigidly attached to the casks. The mass of the MPC and the containing spent fuel is lumped in a free standing rigid cylinder that during the earthquake is free to rattle in the cask cavity. The classical impulse-momentum algorithm simulates the contact of the MPC with the inner sides of the HI TRAC transfer cask. While the VN algorithm has the capability to model coefficient of friction behavior that is a fumction of interface relative velocity, in the simulations herein, we use a constant value for the coefficient of friction. To study the propensity for transporter overturning, a track/ground interface coefficient of friction equal to 0.8 is assumed; similarly, to study sliding behavior, a lower bound coefficient of friction equal to 0.4 is assumed. For the transporter on inclined grade evaluations, the lower bound coefficient of friction is used to maximize transporter sliding displacements.

The analysis model has the cask rigidly attached to the body of the transporter. The transporter is supported by a rigid plate, representing the roadway, that is subjected to a ground displacement or ground acceleration time history. The simulations in this report use a generic model of the cask transporter that has a track width identical to that planned for the Diablo Canyon transporter but has a reduced track length. This ensures, as shown by the quasi-static stability analyses, that the results from the dynamic simulations performed herein bound the response of the real system. The weight of the transporter used in the analysis is based on estimates for the Diablo Canyon transporter.

2.2 Acceptance Criteria Per the Specification for Dry Storage Casks for Diablo Canyon [5.7], the requirement that the transporter plus its carried load must remain stable (not overturn) and remain on the travel path under all postulated seismic events applicable to the Diablo Canyon ISFSI defines the acceptance criteria for the stability analyses of the transporter. The minimum roadway width is 26 feet, which sets the allowable transporter lateral sliding distance. The maximum acceptable sliding movement along the roadway is limited to the cask transporter track length to ensure that the transporter will remain on the roadway after exiting a turn in the roadway.

Holtec Project 1073 Report HI-2012768 10 G:\\Projects\\ I 073\\AIS\\REPORTS\\ HI-2012768\\REV 2\\hi2012768r2.doc

3.0 ASSUMPTIONS 3.1 The time domain dynamic analyses of the transporter seismic stability simulate the modeled components (transporter, cask, and MPC) as rigid bodies with specified geometry and bounding mass. The connection between the cask body and the lids is assumed to be rigid. This is a realistic assumption for the study of system stability. These are conservative assumptions for the seismic analysis since the energy dissipation in the dynamic system is neglected by the virtue of the rigid body modeling.

3.2 The time domain dynamic simulations model the MPC and the contained fuel by a solid cylinder with total mass equal to that of a bounding loaded MPC. This is conservative since all energy dissipation due to fuel assembly rattling inside the MPC is neglected and any reduction in amplitude due to chaotic fuel assembly motion over time is ignored.

3.3 The analyses in time domain are simplified by assuming the rigid bodies to be with uniform mass density when calculating their mass moments of inertia and mass center locations. Any shift in the centroid due to this assumption has negligible effect on the results of the analysis.

3.4 The coefficient of restitution for the contact surfaces (MPC-to-Il-STORM) is set to 0. 0.

The coefficient of restitution between the transporter treads and the ground is set to 0.

0.25 (the exact value has no influence on the solution when sliding motions predominate). For the coefficient of friction at the transporter tread/ground interface, an upper bound value of 0.8 is assumed to emphasize tipping action. A lower bound on the tread/roadway surface is 0.4 [5.8]. Simulations are made herein using both upper and the lower bound. The lower bound value is used to determine maximum sliding excursions while the upper bound value is used to determine the rocking behavior of the transporter.

The coefficient of friction values are assumed to be dynamic coefficients of friction. The coefficient of friction between the MPC and the HI-TRAC cavity side surfaces is set at Holtec Project 1073 Report HI-2012768 11 G:\\Projects\\ I 073\\AIS\\REPORTS\\HI-2012768\\ REV 2\\hi2012768r2.doc

0.5 as a representative of steel-on-steel friction in a dry environment. Any value used at this interface is conservative since the actual connection precludes relative motions to within an assembly tolerance.

3.5 The time domain dynamic simulations use a generic model of the transporter with length of the transporter tracks that are shorter than the length of the DCPP Transporter tracks.

The analyses consider the stability of this transporter when supported by a horizontal ground surface.

3.6 As all bodies are assumed as rigid for the global analysis, the transporter design specification, HI-2002501, includes a requirement that the transporter be designed such that its lowest global natural frequency be in the rigid range (>33 Hz) as defined by the input response spectra for the events considered herein. Once the transporter is designed it is our intent to perform an analysis to verify that it meets the rigidity requirement Holtec Project 1073 Report HI-2012768 12 G:\\Projects\\1 073\\AIS\\REPORTS\\HI-2012768\\REV 2\\hi2012768r2.doc

[5.3]) for a loaded MPC in the cask cavity. For the horizontal orientation, 10,000 lb. is included to approximate the weight of the upending frame.

Holtec Project 1073 Report HI-2012768 14 G:\\Projects\\ 1073\\AIS\\REPORTS\\HI-2012768\\REV 2\\hi2012768r2.doc

Transporter/Ground Damping Coefficient equivalent to 0.25 COR (in level ground analyses using local contact spring, damper model)

The analyses of the sliding stability conservatively use the minimum value of the friction coefficient to provide conservative estimate of the sliding excursions. The dynamic simulations use a maximum value of the friction coefficient in order to investigate the stability of a system that is prone to overturning. For simulations that considered realistic values for coefficient of friction, a value of 0.4 was used (Reference [5.8] lists a friction factor of.45 for crawler tracks on concrete; conservatively, we choose 0.4.).

4.2 Input Earthquake Excitation Pacific Gas & Electric has identified five time histories [5.5]. The low frequency content of these strong motion seismic events ensures that sliding displacements are maximized for the low coefficient of friction cases analyzed. These seismic events are identified below with their duration:

1.

Lucerne Valley (48 sec.)

2a.

Yarimca (40 sec.)

3.

LGPC (22 sec.)

5.

El Centro (40 sec)

6.

Saratoga (40 sec.)

The number identifier is consistent with the PG&E designation. Each seismic set consists of a vertical acceleration time history, and two horizontal time histories, designated as "Fault Normal" or "Fault Parallel with fling".

6.0 ANALYSES AND RESULTS 6.1 Contact Interface Parameters The time domain dynamic analyses of the cask transporter seismic stability require simulation of the interaction at the contacts between the rigid bodies. Three parameters, a friction coefficient, a vertical stiffness constant, and vertical damping constant are used to model the contact of the transporter with the ground surface. In the rigid body model, a series of peripheral springs simulate the contact between the two large flat surfaces undergoing low velocity impacts.

Appendix A calculates the vertical spring rate and damping coefficient. Sixteen (16) facet points represent the contact between the two transporter tracks of the Cask Transporter and the ground at any location on the travel path. The calculations determine the spring and damper, per facet, that are used as input into the "custom contact" VN model at the transporter/ground interface.

The premise for establishing the spring rate is that the responses of interest when considering system behavior to seismic ground motions should focus on the predominate modes below 33 Hz and avoid modeling assumptions that introduce spurious mathematical artifacts that serve only to interject high frequency effects into the simulation. It is noted that the predominate energy in earthquakes is concentrated in the frequency range below 33Hz. Therefore, the contact spring representation employed in the simulation is based on the mass of the unloaded cask transporter, and is developed so that the 33Hz frequency is based on a direct drop of the mass onto a rigid foundation. This renders the custom contact model independent of the local material and geometric shape of the contact surfaces.

Calculations in Appendix A yield the following input values for the contact parameters at the tread/ground interface 0 Vertical linear spring coefficient 1,183 kips/in.

0 Vertical viscous damping coefficient 6.2 Time Domain Dynamic Simulations-General A series of non-linear dynamic simulations are performed using the "VisualNastran 4D" (VN) computer code [5.10] to assess the seismic stability of the transporter during the bounding earthquakes. The simulations analyze the operational modes that include transport of HI-TRAC and H-STORM casks in vertical orientation. The models used for analyses of the HI-STORM and J1I-TRAC configurations are shown on Figure 8. 1 and 8.2, respectively. The dynamic simulations are performed with a variable time step. The maximum integration time step is set at 0.002 sec, a value that ensures an appropriate resolution of the input motion and adequate accuracy of the integration. The friction coefficient has a crucial effect on the overall dynamic behavior of the system. The sliding of the transporter is proportional to the value of the friction coefficient with lower values of friction coefficient resulting in larger sliding displacements. The high values of the friction coefficient restrict the transporter sliding making it prone to overturning. Although the simulation algorithm permits the use of a velocity dependent friction coefficient, herein, the coefficient of friction is held constant (at either 0.4 or 0.8) through the entire duration of the simulation.

A series of dynamic simulations have been performed to evaluate transporter stability. The combinations of grade, coefficient of friction, and seismic events have been chosen to be representative of bounding conditions at the site.

For simulations in Phases 2-4, the designator of N or P means that the component (N for Fault Normal and P for Fault Parallel) is aligned down-slope.

The specific cases run are defined in e-mail transmittal of 8/31/01 from PG&E (R. Klimczak) to Holtec.

For each case considered, the loaded transporter is assumed to be on a flat or inclined surface with specified coefficients of friction. The simulations performed under Phase 1 serve to identify potentially bounding events from among the five candidate time histories. The choice of simulations fbr the remaining phases is based on the results from the simulations in Phase 1. The combination of grade and coefficient of friction are such as to induce sliding as opposed to tipping. Therefore, in the simulations on a non-zero grade (Phases 2-4), the transporter and the load are not modeled in detail per Figure 8.1 and 8.2, but are simulated as a simple rigid block with an appropriate bounding centroid location and having interface dimensions with the roadway equal to the length and width of the proposed Diablo Canyon transporter. Simulations Holtec Project 1073 Report HI-2012768 23 G:\\Projects\\ 1073\\AIS\\REPORTS\\HI-2012768\\REV 2\\hi20 I2768r2.doc

on flat surfaces (Phases 1 and 5), however, use the detailed model in Figure 8.2 and 8.1, respectively. In the analyses, we use

- The transporter weight is 170,000 lb.

- The HI-TRAC weight is 250,000 lb. (tie-down rigging neglected as it should lower the c.g)

- The HI-STORM weight is 360,000 lb.

The width of the roadway is 26'= 312". The width of the transporter (outside of track-to-outside of track) is approximately 212"; therefore, there is just over 4' of span to the edge of the roadway.

6.3 Time Domain Simulations on Level Ground-Phases I and 5 Five seismic events are considered on level ground with the HI-TRAC in a horizontal orientation Peak displacements of the transporter relative to the road are given in Table 2, below: For all cases in Phase 1, the Fault Parallel time history is aligned along the road, and the Fault Normal time history is aligned transverse to the road. All simulations are assumed to occur on a level roadway. Figure 8.2 is the simulation model for all events in Phase 1.

From the above results, we choose seismic event 6 to form the input for a bounding evaluation of the transporter carrying a loaded HI-STORM. The results from this simulation will demonstrate whether there is any credible overturning scenario from a seismic event. Table 3 summarizes the results of this evaluation; the results are presented in graphical form in Figure 8.8. The graphs give the time history of the displacement of the lid center and a point on the transporter relative to an origin of coordinates on the road (x=y=z=0.0 inch). It is clear from the results that overturning of a loaded transporter during a seismic event is not credible. Table 3 summarizes the results. In each direction, the starting position, the maximum position, and the minimum position, relative to the origin of coordinates is listed. The final position, relative to the origin of coordinates, can be read from the graphs TABLE 3 - PHASE 5 RESULTS TRANSPORTER STABILITY DISPLACEMENT RESULTS (Relative to Origin of Coordinates) - PHASE 5 -0% Grade-HI--STORM with cof=0.8 Time History Set Longitudinal (inch)

The previous simulations have clearly demonstrated that transporter overturning is not credible; however, because of the grade, the demand on frictional resistance is increased since the net download has a component parallel to the roadway. Therefore, we next examine the consequences of a ratcheting behavior where the loaded transporter exhibits a propensity to slide down the path under the action of the imposed seismic loading. The location of the system center of gravity is unimportant for this study; therefore, an evaluation of longitudinal sliding while on an inclined grade is undertaken using a simple box to represent the transporter plus load sliding down the incline on a fixed ground. The centroid of the box representing the transporter plus load is set higher than the actual system; the weight of the box are the bounding weights of 420 kips (HI-TRAC + transporter) or 530 kips Holtec Project 1073 Report HI-2012768 25 G:\\Projects\\ I 073\\AIS\\ REPORTS\\ HI-2012 76 8\\REV 2\\hi2012768r2.doc

(HI-STORM+transporter), the coefficient of friction is 0.4, and 6% and 8.5% grades are considered. The seismic driving mechanism for these simulations is a 3-D inertia force, proportional to the three components of seismic acceleration, applied at the mass center of the box. The results for maximum transporter displacements are shown in the tables below and summarized in graphical form in Figures 8.9-8.15. The graphical results of interest are the position of a point on the transporter relative to the origin of coordinates set in the road. The displacement along (parallel) to the roadway can be obtained from the horizontal (x) component by dividing by the cosine of the incline angle corresponding to the incline. Note that the figures show a slight offset in each of the displacement coordinates. This is simply due to not "zeroing" the initial position between the measuring point on the transporter and the origin of coordinates.

In the summary tables given below, we show the starting location of the tracked point, and the maximum and minimum excursions, relative to the origin of coordinates on the road (x = y = z =

0.0 inch). Only the results in the plane of the road are listed Incline 8.5% corresponds to incline angle A = 4.858 degrees from horizontal (cosA=0.9964)

Incline 6.0% corresponds to incline angle A = 3.434 degrees from horizontal (cosA=0.9982)

.228/10.870/.216 6.5 Stability of TransporterlCask With Large Tornado Missile Impact The HI-STORM FSAR contains analyses that demonstrate stability against overturning and sliding when the cask is subject to a large tornado missile strike plus tornado wind. Although the impact height is increased, the transporter width over the outside of the tracks is approximately double the diameter of the HI-STORM. Therefore, it is expected that tornado missile strikes will not lead to an overturning or excessive sliding scenario. To conclusively demonstrate this, the VN model of the transporter on level ground, carrying a HI-STORM in the vertical orientation, was modified to include a horizontal large tornado missile striking at the top of the transporter.

The large tornado missile used was the same as the FSAR large missile; namely, a rigid cylinder with a 20 sq. ft. frontal area simulated a 4000 lb. car traveling at 126 mph The car was conservatively assumed to be a rigid body even though it would be expected to locally crush Holtec Project 1073 Report HI-2012768 27 G:\\Projects\\ 1 073\\AIS\\REPORTS\\ HI-2012768\\ REV 2\\hi2012768r2.doc

during transporter impact and absorb a good portion of the kinetic energy. The missile strike was assumed in the transverse direction to maximize the propensity for overturning. Tornado wind effects were ignored since if the wind cannot overturn a freestanding HI-STORM on a pad, it cannot overturm a loaded or empty transporter with its much larger contact width. The following table summarizes the results obtained from the analyses performed; Figures 8.16 through 8.18 provide a graphical summary of each simulation. Each figure shows the configuration at a single instant of time and the location of the strike. We note that the empty transporter shows the most propensity for overturning since it has the smallest weight and inertia compared to the impacting missile and therefore offers less resistance to overturning than does the loaded system.

7.0 CONCLUSION

S Time domain dynamic simulations presented in this report demonstrate that the transporter, loaded with spent fuel casks in a vertical or horizontal orientation, maintains its seismic overturning stability and is secure from sliding off the road while moving on the Diablo Canyon ISFSI pad. If the transporter is on level ground, the maximum excursion is below l0"in any direction, a value that is less than the distance to the edge of the roadway. If the design basis seismic event occurs while the transporter is on an incline, the maximum movement down the incline is approximately 10% of the length of the transporter and the transporter stays on the road.

Tornado missile impacts are evaluated and dynamic analyses demonstrates that there is no dynamic instability or excessive sliding for either a loaded system or the transporter alone.

PREFACE This Calculation Package has been prepared pursuant to the provisions of Holtec Quality Procedures HQP 3.0 and 3.2, which require that all analyses utilized in support of the design of a safety-related or important-to-safety structure, component, or system be fully documented such that the analyses can be reproduced at any time in thefitture by a specialist trained in the discipline(s) involved. HQP 3.2 sets down a rigid format structure for the content and organization of Calculation Packages which are intended to create a document which is complete in terms of the exhaustiveness of content. The Calculation Packages, however, lack the narrational smoothness of a Technical Report, and are not intended to serve as a Technical Report.

Accordingly, this Calculation Package is compiled to provide archival information to supplement the material presented in Diablo Canyon Safety Analysis Report. The material presented in this Calculation Package is not needed to comprehend the material presented in the above-mentioned Technical Report (which is a self-contained document in full compliance with the USNRC regulations), unless the reader wishes to examine the computational details.

The purpose of each discrete calculation is explicitly stated in this compendium of calculations and the specific location in the above-mentioned technical report, which it is intended to supplement, is clearly indicated.

Because of its function as a repository of all analyses performed on the subject of its scope, this document will be revised only if an error is discovered in the computations or the equipment design is modified. Additional analyses in the future will be added as numbered supplements to this Package. (Each time a supplement is added or the existing material is revised, the revision status of this Package is advanced to the next number and the Table of Contents is amended).

EXECUTIVE

SUMMARY

t A central objective of a storage overpack is to maintain the integrity of the "confinement boundary", namely, the multi-purpose canister (MPC) stored inside. This operational imperative requires that the mechanical loadings associated with a tornado do not jeopardize the physical integrity of the loaded MIPC. Potential consequences of a tornado on the cask system are:

"* Instability (tip-over) due to tornado wind load combined with either tornado missile impact or impulse from tornado pressure drop.

"* Stress in the cask induced by the lateral force caused by the steady wind or missile impact.

Loadings applied on the MPC transmitted to the inside of the cask through its openings or as a secondary effect of loading on the enveloping overpack structure.

Excessive cask deformation which may prevent ready retrievability of the MPC.

"* Excessive cask deformation which may significantly reduce the shielding effectiveness of the storage overpack.

At DCPP, the following missiles are postulated to impact the H[-TRAC transfer cask inside the Fuel Handling Building (FIB).

108 pound, 4-inch x 12-inch x 10-foot board traveling at 150 mph

76 pound, 3-inch x 10-foot schedule 40 pipe traveling at 50 mph t The Executive Summary is a self-contained write-up of the wind load and tornado generated missile evaluation for DCPP, which is intended for direct insertion in the DCPP Safety Analysis Report (SAR).

Report HI-2002497 3

Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

Of particular interest is the case of a missile impact on the transfer cask and lift yoke after the loaded cask, with its lid unwelded, is lifted out of and above the SFP. Although the MPC is unsealed during this operation, this condition is no more critical than the conditions outside of the FIHB since a MPC retention lid will be bolted to the HI-TRAC transfer cask for added protection.

Based on comparisons of the quantity (MV2)/D, where M is the mass of the missile, V is the velocity of the missile, and D is the equivalent diameter of the missile, the 8-inch diameter steel cylinder (125 kg, 126 mph) analyzed in the rn-STORM FSAR bounds the two missiles listed above. Therefore, the results and conclusions from the FSAR are valid for the DCPP missiles inside the FRB and the Aux. Bldg.. The only scenario that is not analyzed in the FSAR is a direct missile strike on the cask lift yoke, which may potentially cause a loss of load.

The most vulnerable location on the cask lift yoke is the lift arm. The cross section of the lift arm is weaker (i.e., has a lower section modulus) in the direction parallel to its plane of rotation.

Thus, the evaluation considers three bounding missile impacts in this direction. An impact on the inside surface produces a moment that tends to rotate the lift arm outward, away from the HI TRAC, possibly disconnecting the lift arm from the trunnion. If the impact occurs on the outside surface, the lift arm may collapse due to the lateral force of the impact. Finally, if the impact occurs near the top of the lift arm, a shear failure may occur. These three scenarios are analyzed using classical methods. The following results are obtained.

i.

The maximum moment produced by a missile impact on the inside surface of the lift arm is 1.003 x 106 lbf-in. By comparison, friction between the lift arm and the IHI-TRAC trunnion is capable of producing a resisting moment up to 2.995 x 106 lbf-in. Since the frictional resistance is greater than the impact moment, the lift arm will not rotate.

Report MI-2002497 4

Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

ii.

The maximum combined stress (i.e., axial plus bending) in the lift arm due to a missile impact on the outside surface is 47,191 psi, which is less than the ASME Subsection NF stress limit of 109,200 psi for Level D conditions. Thus, the lift arm will not collapse due to a missile impact.

iii.

The maximum shear stress in the lift arm due to a missile impact near the top of the arm is 1,302 psi, which is far less than the ASME Subsection NF stress limit of 72,800 psi for Level D conditions. Thus, the lift arm will not experience a shear failure due to a missile impact.

The above results demonstrate that there will be no loss of load due to a missile impact while handling the transfer cask inside the FHB or the Aux. Bldg.. Furthermore, the 125-ton HI-TRAC cask satisfies all functional requirements under the postulated impact scenarios.

Outside the F-B, there are a host of missiles to consider, which can be divided into three categories (i.e., small, intermediate, and large) based on their size and weight. In the small missile category, the bounding missile (based on kinetic energy comparisons) is a 1-inch diameter steel rod traveling at 40 m/sec (89.5 mph). This missile is analyzed only for the loaded HI-STORM because, unlike the transfer cask, it has cooling vents that allow the missile to enter inside the cask. For the HI-TRAC transfer cask, the small missile is ignored because the intermediate missile, a 760 lb insulator string traveling at 157 mph, causes more damage.

Finally, the two automobile missiles postulated at DCPP are bounded by the large missile analyzed in the HI-STORM FSAR.

The missile impacts are analyzed using formulas from Topical Report BC-TOP-9A, "Design of Structures for Missile Impact," and energy balance methods. The following results are obtained for the small and intermediate missiles.

Report I-t-2002497 5

Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

i.

The 1-inch diameter steel rod (i.e, small missile) is postulated to enter an inlet duct and impact the pedestal shell, which is the most vulnerable location on the HI-STORM cask.

The analysis shows that the rod will pierce the shell and penetrate the concrete to a depth of 6.179 inches, which is significantly less than the radius of the pedestal shield. The damage to the concrete pedestal shield does not affect the confinement boundary nor does it affect the retrievability of the MPC. The net effect on the cask's shielding ability is negligible.

ii.

The intermediate missile will not penetrate the 1-11/44" inner shell of the HI-STORM cask.

The minimum required thickness to withstand the missile impact is 0.619 inches.

iii.

The intermediate missile will not penetrate the 2" top lid of the HI-STORM cask. The minimum required thickness to withstand the missile impact is 1.089 inches.

iv.

The intermediate missile will not penetrate the 3/4" inner shell of the HI-TRAC cask. The minimum required thickness to withstand the missile impact is 0.266 inches.

v.

When the HI-TRAC is transferred horizontally outside of the FHB, the potential exists for a missile strike on the bottom transfer lid door. The analysis shows that the intermediate missile will not penetrate the 2-1/4" top plate of the transfer lid door. The minimum required thickness to withstand the missile impact is 0.619 inches.

vi.

The top lid of the HI-TRAC has a central hole for rigging the MPC, which is normally protected by the cask transporter (i.e., crawler). However, if the intermediate missile directly impacts the MPC top lid, the safety factor against failure of the peripheral weld is 7.103.

vii.

Away from the impact locations, stresses in the overpack are below ASME Code Level D stress limits.

Report MI-2002497 6

Project 1073

\\\\projects\\1073\\cbullardU-i2002497.doc

viii.

The maximum moment at the base of the anchored cask, due to the wind and missile loads, is 2,448 kip-ft. This is below the moment induced by the seismic loads.

The above calculations demonstrate that the rI-STORM 100 Overpack and the 125-ton Il-TRAC transfer cask provide effective missile barriers for the MPC. No missile strike compromises the integrity of the confinement boundary. In addition, global stresses intensities arising from the missile strikes satisfy ASME Code Level D limits for an ASME Section III Subsection NF structure.

1.0 PURPOSE AND SCOPE The purpose of this report is to evaluate the postulated wind and tornado loads at Diablo Canyon Power Plant (DCPP) as specified in Sections 6.2.1 and 6.2.2 of the Client Specification [1.1].

The wind and tornado loads are considered for a sequence of events, which follow the fuel from the initial loading in the SFP to final storage on the ISFSI pad.

Report HI-2002497

\\\\projects\\1073\\cbullard\\hi2002497.doc 9

Project 1073 I

2.0 METHODOLOGY The first step in the analysis is to compare the postulated wind and tornado loads at DCPP with the design basis loads in the HI-STORM 100 TSAR [2.1]. The bounding missile in each category' (i.e., small, intermediate, large) is the missile with the highest kinetic energy. Initial comparisons of the missiles were carried out in Holtec report I1-2002478 [2.2, Appendix A].

If the TSAR missiles are determined to bound all of the DCPP missiles, then the evaluation is complete. If not, impact analyses must be performed for the bounding DCPP missiles. The missile impacts are analyzed in a manner that is consistent with Appendices 3.C, 3.G, and 3.H of the rI-STROM 100 TSAR [2.1].

A separate analysis is performed in Appendix D of this report to determine the consequences of a missile impact between a 3-inch diameter pipe and the cask lift yoke. This analysis uses basic strength of material formulas to measure the damage.

1 The missiles are characterized as small, intermediate, or large based on their size and weight.

Report 11H-2002497

\\\\projects\\1 073\\cbullard\\hi2002497.doc 10 Project 1073

3.0 ACCEPTANCE CRITERIA In this section, the word "cask" refers to both the HI-STORM and Fil-TRAC casks.

The acceptance criteria for the wind and tornado load evaluation are:

a)

The loaded cask does not become kinematically unstable (i.e., tip-over) as a result of the postulated wind loads and/or a tornado missile impact.

b)

The stresses in the cask do not exceed Level D stress limits away from the immediate impact location.

c)

The missiles do not breach the MPC enclosure vessel ("confinement boundary").

d)

The cask does not deform plastically such that the retrievability of the stored MPC is threatened.

e)

The cask does not deform plastically such that the shielding effectiveness of the cask is significantly affected.

7.0 ANALYSIS The postulated wind loads and tornado generated missiles are analyzed for a sequence of events, which follow the fuel from the initial loading in the SFP to final storage on the ISFSI pad. The events are defined by the following time periods.

a)

During fuel loading operations in the SFP b)

During handling of the hI-TRAC by the FIBB crane c)

During activities in the cask washdown area d)

During staging activities in the Shipping and Receiving area and in the Yard outside the F-B e)

During transport to the Cask Transfer Facility (CTF) f)

During MPC transfer at the CTF g)

During transport to the ISFSI site h)

During long term storage on the ISFSI pad These events are subject to different wind loads and different missiles depending on their location inside or outside of the FBIB. The type of analysis performed for each event is described in the following paragraphs.

a)

During fuel loading operations in the SFP During fuel loading operations, the MPC is submerged in the SFP. Although tornado missiles can still enter the pool, the SFP water will dissipate the missile velocities. Therefore, due to the protection of the water, the wind and tornado loads while the MPC is in the pool are bounded by the loads outside of the pool. No analysis is required for this event.

Report I-i-2002497 16 Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

b)

During handling of the Jil-TRAC by the FHB crane Inside the FHB and the Aux. Bldg., there are only two postulated missiles (refer to paragraph 5.3.b), a 76 pound, 3-inch x 10 feet schedule 40 pipe and a 108 pound 4-inch x 12-inch x 10 feet board. Both of these missiles are bounded (i.e., lower kinetic energy) by the intermediate missile analyzed in the rn-STORM TSAR [2.1, Appendix 3.H]. Therefore, the results and conclusions from the TSAR can be applied to missile impacts during this event.

A new analysis is required to demonstrate that a direct missile impact on the cask lift yoke will not cause a loss of load. Appendix D evaluates the consequences of a missile impact at the most vulnerable locations on the cask lift yoke.

The wind loads analyzed in the rn-STORM TSAR bound any probable wind loads inside the FEB and the Aux. Bldg.. Therefore, the results and conclusions from the TSAR can be applied to wind loads during this event.

c)

During activities in the cask washdown area The postulated missiles inside the FHB are bounded (i.e., lower kinetic energy) by the intermediate missile analyzed in the HI-STORM TSAR [2.1, Appendix 3.M1.

Therefore, the results and conclusions from the TSAR can also be applied to missile impacts in the cask washdown area.

The wind loads analyzed in the rn-STORM TSAR bound any probable wind loads inside the FEB and the Aux. Bldg.. Therefore, the results and conclusions from the TSAR can be applied to wind loads during this event.

d)

During staging activities in the Shipping and Receiving Area and in the Yard outside the FIIB There are a host of missiles to consider in the Yard outside the FHB. These missiles can be divided into three categories (small, intermediate, and large) based on their size and weight. The small missiles have no significant effect on the loaded IHI-TRAC because the transfer cask has no vents or openings that permit a direct impact on the MPC. In the intermediate category, the bounding missile is the 760 lb insulator string traveling at 157 mph (refer to paragraph 5.3.c).

Three different impact locations on the transfer cask are analyzed in Appendix B. This appendix also considers a direct impact on the MPC lid through the center hole on the tII-TRAC top lid.

Finally, the two automobile missiles postulated for DCPP are bounded by the large missile analyzed in the IHI-STORM TSAR [2.1, Appendix 3.AN].

The design basis wind load and the tornado wind load at DCPP are also bounded by the tornado wind characteristics analyzed in the HI-STORM TSAR [2.1, Table 2.2.4].

e)

During transport to the Cask Transfer Facility (CTF)

The wind loads and missiles for this event are identical to those described in paragraph d). The bounding intermediate missile, a 760 lb insulator string, is analyzed in Appendix B. The remaining missiles are bounded by the results from the HI-STORM TSAR [2.1]. The cask transporter has redundant drop protection; therefore, a loss of load due to a direct missile strike on the transporter is not plausible.

The design basis wind load and the tornado wind load at DCPP are bounded by the tornado wind characteristics analyzed in the rI-STORM TSAR [2.1, Table 2.2.4].

Report 1I-2002497 18 Project 1073

\\\\projects\\1073\\cbullard~hi2002497.doc

f)

During MPC transfer at the CTF At the CTF, the MPC is transferred from the 125-ton HI-TRAC to the rH-STORM 100. As a result, the rn-STORM 100 must be analyzed for the postulated missile impacts. Unlike the transfer cask, the rI-STORM 100 has several cooling vents, which allow small missiles to enter inside. In this category, the bounding missile is the 1-inch diameter steel rod traveling at 40 m/sec (Spectrum HI missile). This missile, as well as the 760 lb intermediate missile, is analyzed in Appendix C. Appendix C also computes the global stresses in the H1-STORM overpack due to missile impact. As before, the large missiles are bounded by the results from the rH-STORM TSAR [2.1, Appendix 3.C].

The design basis wind load and the tornado wind load at DCPP are bounded by the tornado wind characteristics analyzed in the rH-STORM TSAR [2.1, Table 2.2.4].

Since the CTF structure at DCPP is underground, it is not exposed to missile impacts.

g)

During transport to the ISFSI site The wind loads and missiles for this event are identical to those described in paragraph f). The small and intermediate missiles are both analyzed in Appendix C. The large missiles are bounded by the results from the HI-STORM TSAR [2.1, Appendix 3.C].

The design basis wind load and the tornado wind load at DCPP are bounded by the tornado wind characteristics analyzed in the HI-STORM TSAR [2.1, Table 2.2.4].

h)

During long term storage on the ISFSI pad The wind loads and missiles for this event are identical to those described in paragraph f). The small and intermediate missiles are both analyzed in Appendix C. The large missiles are bounded by the results from the HI-STORM TSAR [2.1, Appendix 3.C].

Report I-H-2002497 19 Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

At DCPP, the storage casks will be anchored to the ISFSI pad. Therefore, the wind and missile loads will produce a moment (M) at the base of the cask, whose magnitude is given by the following equation:

M = 0.5WH + Fh where:

W equals the resultant force on the cask due to tornado wind; H equals the height of the cask (231.25 in);

F equals the lateral force on the cask due to missile impact; h equals the height of the missile impact above the base (231.25 in).

From the FIf-STORM TSAR [2.1], the resultant force on the cask due a 360 mph tornado wind is 3.273 x I0l lb (Appendix 3.C), and the maximum force due to a large missile impact is 4.569 x 105 lb (Appendix 3.AN). The corresponding tornado wind force and nmissile impact force at DCPP are computed as follows:

W = 3.2 7 3 xl 0 4lb 2,0mph) = 1.1O0x1041b M =4.569x1051b (r40001) 333mph) 1.220x10 51b When these values are substituted into the above equation, the moment at the base of the cask equals 2,-448 kip-ft. As shown in Holtec report I-t-2012618 [7.1], this moment is bounded by the seismic induced moment.

9.0 RESULTS At DCPP, the bounding missiles in the small and intermediate categories are the 1-inch diameter steel rod and the 760 lb insulator string, respectively. The deformations and stresses in IHI STORM 100 Overpack due to these two missiles are reported in Appendix C. Similar results are reported in Appendix B for two postulated impacts between the 760 lb insulator string and the 125-ton HI-TRAC. Appendix D shows that a direct missile impact on the cask lift yoke will not cause loss of load. The results are summarized below.

i.

The 1-inch diameter steel rod (i.e, small missile) is postulated to enter an inlet duct and impact the pedestal shell, which is the most vulnerable location on the II-STORM cask.

The analysis shows that the rod will pierce the shell and penetrate the concrete to a depth of 6.179 inches, which is significantly less than the radius of the pedestal shield. The damage to the concrete pedestal shield does not affect the confinement boundary nor does it affect the retrievability of the MPC.

ii.

The intermediate missile will not penetrate the 1-114" inner shell of the rn-STORM cask.

The minimum required thickness to withstand the missile impact is 0.619 inches.

iii.

The intermediate missile will not penetrate the 2" top lid of the rI-STORM cask. The minimum required thickness to withstand the missile impact is 1.089 inches.

iv.

The intermediate missile will not penetrate the 3/4" inner shell of the HIl-TRAC cask. The minimum required thickness to withstand the missile impact is 0.266 inches.

v.

When the JIl-TRAC is transferred horizontally outside of the FEB, the potential exists for a missile strike on the bottom transfer lid door. The analysis shows that the intermediate missile will not penetrate the 2-1/4/4" top plate of the transfer lid door. T'he minimum required thickness to withstand the missile impact is 0.619 inches.

Report 1I--2002497 22 Project 1073

\\\\projects\\1073\\cbullard\\hi2002497.doc

vi.

The top lid of the I-m-TRAC has a central hole for rigging the MPC, which is normally protected by a missile shield plate. However, if the intermediate missile directly impacts the MPC top lid, the safety factor against failure of the peripheral weld is 7.103.

vii.

The maximum moment produced by a missile impact on the inside surface of the lift arm is 1.003 x 106 lbf-in. By comparison, friction between the lift arm and the I-i-TRAC trunnion is capable of producing a resisting moment up to 2.995 x 106 lbf-in. Since the frictional resistance is greater than the impact moment, the lift arm will not rotate.

viii.

The maximum combined stress (i.e., axial plus bending) in the lift arm due to a missile impact on the outside surface is 47,191 psi, which is less than the ASME Subsection NF stress limit of 109,200 psi for Level D conditions. The maximum shear stress in the lift arm due to a missile impact near the top of the arm is 1,302 psi, which is far less than the ASME Subsection NF stress limit of 72,800 psi for Level D conditions. Thus, the lift arm will not fail due to a missile impact.

ix.

Stresses in the overpack are below Level D stress limits away from the immediate impact locations.

x.

The maximum moment at the base of the anchored cask, due to the wind and missile loads, is 2,448 ldp-ft. This is below the moment induced by the seismic loads.

The transfer cask is not analyzed for a small missile impact, since I-H-TRAC does not have any vents or openings that allow a missile to enter inside. With respect to the HI-TRAC transfer cask, the intermediate missile clearly bounds the small missile. The large missile analyzed in the HI-STORM TSAR bounds the automobile missiles at DCPP.

In addition, the design basis wind and the tornado wind at DCPP are bounded by the tornado wind characteristics analyzed in the HI-STORM TSAR.

10.0 CONCLUSION

This report demonstrates that the r-n-STORM 100 Overpack and the 125-ton I-l-TRAC transfer cask provide effective missile barriers for the MPC, No missile strike compromises the integrity of the confinement boundary. In addition, global stresses intensities arising from the missile strikes satisfy ASME Code Level D limits for an ASME Section III Subsection NIF structure.

PREFACE This calculation package has been prepared pursuant to the provisions of Holtec Quality Procedures HQP 3.0 and 3.2, which require that all analyses utilized in support of the design of a safety-related or important-to-safety structure, component, or system be fully documented such that the analyses can be reproduced at any time in the future by a specialist trained in the discipline(s) involved. HQP 3.2 sets down a format for the content and organization of calculation packages that are intended to create a document that is complete in terms of the exhaustiveness of content. The calculation packages, however, lack the narrational smoothness of a technical report, and are not intended to serve as a technical report.

Because of its function as a repository of all analyses performed on the subject of its scope, this document will require a revision only if an error is discovered in the computations or the equipment design is modified. Additional analyses in the future may be added as numbered supplements to this package. Each time a supplement is added or the existing material is revised, the revision status of this package is advanced to the next number and the table of contents is amended. Calculation packages are Holtec proprietary documents. They are shared with a client only under strict controls on their use and dissemination.

This calculation package will be saved as a permanent record under the company' s QA System.

1.0 Introduction Section 72.122 of the Code of Federal Regulations [1] defines the requirements for licensing basis evaluations of explosion events at a proposed independent spent fuel storage installation (ISFSI). Section 6.2.8 of the Pacific Gas and Electric (PG&E) specification [2] for an ISFSI at the Diablo Canyon Power Plant (DCPP) postulates a number of site explosion hazards that could possibly affect proposed ISFSI structures, systems and components (SSCs) that are important-to safety. This report is issued to document the analyses performed to quantify the effects, if any, of the postulated explosion hazards on the storage and transfer casks that will be used at the DCPP ISFSI.

The following sections of this document present the computational methods and input data used to perform the explosion hazard evaluations (Sections 2.0, 4.0 and 5.0), the acceptance criteria applied to the computational results (Section 3.0), the evaluations themselves (Section 6.0), and the numeric calculation results and final conclusions.

Holtec Report HI-2002512 Holtec Project 1073 page 2

2.0 Methodology 2.1 Evaluation of Explosion Potential A total of six potential explosion hazards are listed in the PG&E specification [2]. Before performing calculations to evaluate the effects of these hazards, an engineering evaluation is performed to determine the actual potential for explosion posed by each hazard. If the potential for explosion for an individual hazard is negligible, no subsequent calculations of explosion effects are required.

The engineering evaluation performed for each postulated hazard consists of a review of the applicable physical and chemical properties of the materials involved. Each material detonation hazard is evaluated for explosion potential on the basis of its flash point and explosion hazard rating. The explosion hazard rating for a commercially available material is typically found on the manufacturer' s material safety data sheet (MSDS).

2.2 Evaluation of Explosion Effects The postulated explosion hazards fall into two categories. The first category, which comprises the majority of the postulated hazards, is the detonation of a fuel-air mixture. The methodology for evaluating these hazards is described in Subsection 2.2.1. The methodology for evaluating the hazards in the second category, an impact from a ruptured compressed gas cylinder, is described in Subsection 2.2.2.

2.2.1 Material Detonations USNRC Regulatory Guide 1.91 [3] states: "..for explosions of the magnitude considered in this guide and the structures, systems, and components that must be protected, overpressure effects are controlling." In accordance with this regulatory position, the effects of the postulated explosion hazards will be evaluated by determining the magnitude of the explosive overpressure at the location of the affected cask systems. Due to the extremely short duration of explosion events any heat input to the cask would be negligible, so no temperature calculations are performed.

The magnitude of the overpressure that acts on a cask system is a function of the calorific energy released and the distance between the cask and the explosion. The first step in these evaluations is, therefore, computation of the total calorific energy released during detonation. This computation is performed using the following formula:

E = mxHVxY (2-1) where:

E is the detonation energy m is the mass of material HV is the material heating value Y is an explosive yield factor Holtec Report HI-2002512 Holtec Project 1073 page 3

The use of the explosive yield factor recognizes that only a relatively small percentage of the total heat energy in a material is released by detonation. The remaining heat energy is released during normal combustion subsequent to detonation and does not contribute to the detonation overpressure. Explosive yield factors for hydrocarbon vapor clouds in air are typically between 0.03 and 0.06 (i.e., 3% - 6% yield) [4].

It is common practice in evaluating explosion overpressures to convert all detonation energy quantities into equivalent weights of trinitrotoluene (TNT). This is accomplished by dividing the given detonation energy by the detonation energy of TNT [5], as:

W

=

E (2-2)

Erm where:

WTNr is the equivalent weight of TNT ETrr is the detonation energy of TNT An exhaustive investigation into the effects of explosions on structures, including the development of data for overpressure magnitude versus explosion size and distance, has been performed by the U.S. Army [5]. Using the published U.S. Army methodology of for ground burst explosions, the equivalent weight of TNT and the separation distance between the explosion and the casks systems are used to determine a scaled ground distance, defined as:

x ZG -

V/3 (2-3)

WTNT where:

ZG is the scaled ground distance X is the separation distance Typical units for the scaled ground distance are ft per lb 113 of TNT. Curves that relate incident overpressure and scaled ground distance [5] are utilized to determine the overpressure that will act on the cask systems at the DCPP ISFSI.

2.2.2 Compressed Gas Cylinder Impacts The internal pressures of compressed gas cylinders are frequently in excess of two thousand pounds per square inch. The potential energy at such high pressures is significant and any cylinder ruptures can be catastrophic. The large energy release that can accompany conversion of this potential energy into kinetic energy could potentially damage SSCs important to safety and must be evaluated.

To determine the effects of catastrophic cylinder ruptures on the DCPP ISFSI cask systems, it is postulated that high-pressure compressed gas cylinders fail such that the valve assemblies break off. This failure mode would create an approximately 2-inch diameter hole in one end of the cylinder, and the escaping compressed gas would impart a large acceleration on the cylinder body.

Holtec Report HI-2002512 Holtec Project 1073 page 4

PROPRIETARY INFORMATION DELETED Holtec Report HI-2002512 Holtec Project 1073 page 5

PROPRIETARY INFORMATION DELETED Newton' s third law of motion requires that the thrust force must act to accelerate the gas cylinder in the opposite direction of the expanding gas motion. Thus, knowing the mass of the gas cylinder, including the mass of any contained gas, the instantaneous acceleration of the cylinder can be determined from Newton' s second law of motion as:

F a

+

Mcyl + Meg where:

a is the acceleration of the gas cylinder Mcyl is the mass of the empty cylinder MCg is the mass of contained gas (2-9)

It should be noted that Equation 2-9 conservatively neglects the effects of drag, which would oppose the thrust force and reduce the acceleration of the cylinder. It should also be noted that the mass of contained gas (M cg) reduces over time as gas escapes through the opening in the cylinder.

PROPRIETARY INFORMATION DELETED Holtec Report HI-2002512 Holtec Project 1073 page 6

PROPRIETARY INFORMATION DELETED The postulated high-pressure compressed gas cylinder failure mode (i.e., separation of the valve assembly) will also result in the valve assembly being accelerated by the escaping compressed gas. Thus, the velocity of the valve assembly must also be evaluated. An experimentally developed correlation for the velocity of an end cap or a single, large fragment (i.e., the valve assembly) ejected from a cylindrical vessel pressurized with an ideal gas is [10]:

Vf =2xF'5 xa, F -P xAxR (2-10)

Mxae2 where:

Vf is the end cap or fragment velocity ak is the sonic velocity in the compressed gas prior to rupture Pe is the compressed gas pressure prior to rupture A is the projected area of the fragment R is the radius of the cylindrical vessel M is the mass of the fragment It should be noted that, in Equation 2-10, the sonic velocity (a e) cancels out when the two parts of the correlation are combined. As the sonic velocity is the only term in Equation 2-10 that is gas dependent, this means that the velocity of the ejected valve assembly will be the same for all compressed gases.

Holtec Report HI-2002512 Holtec Project 1073 page 7

Once accelerated by the expanding contained gases, a cylinder or valve assembly presents a missile hazard to the HI-TRAC transfer cask or a HI-STORM storage cask. One function of the HI-TRAC transfer and HI-STORM storage casks is to provide physical protection for the contained multipurpose canister (MPC), which forms the confinement boundary for the radioactive materials within. The HI-TRAC and HI-STORM must, therefore, be capable of preventing any missiles that result from high-pressure gas cylinder failures from damaging the MPC.

A method for predicting the penetration of structures by missile impacts [11] has been previously accepted by the USNRC and has been used in the HI-STORM FSAR [8] for evaluating tornado missile impacts. The penetration of a missile into steel is given by the following equation:

FpxD (2-11) where:

T is the thickness of penetration M is the mass of the missile V is the velocity of the missile Fp is a constant, equal to 672 [(ft-lb f)2/3]/in2 D is the diameter of the missile impact area It is observed that, in Equation 2-11, the missile penetration is proportional to the missile kinetic energy and inversely proportional to the missile impact area diameter.

Holtec Report HI-2002512 Holtec Project 1073 page 8

3.0 Acceptance Criteria 3.1 Evaluation of Explosion Potential These evaluations are performed to determine if a postulated explosion hazard poses a real hazard to the cask systems. The following acceptance criteria are applied in making these determinations.

I.

For flammable vaporized liquids or gases mixed with air, a postulated hazard will be determined to pose a real hazard if the flash point of the material is less than or equal to the ambient temperature. The annual maximum site temperature is 85 'F [2].

2.

For flammable vaporized liquids or gases mixed with air, a postulated hazard will be determined to pose a real hazard if an MSDS sheet lists the explosion hazard rating as other than none.

If any one of these criteria is met for a postulated hazard, the hazard will be deemed a real hazard and evaluated further.

3.2 Evaluation of Explosion Effects 3.2.1 Material Detonations These evaluations are performed to determine the effects, on the casks systems, of all postulated explosion hazards identified as real hazards. The following acceptance criterion is applied in making these determinations.

1.

For all real explosion hazards, stresses in cask system SSCs resulting from the incident explosive overpressure must not exceed allowable stress levels as defined in the cask system Final Safety Analysis Report (FSAR) [8, 9]. Demonstration that a normal, off normal or accident condition already evaluated satisfactorily in the FSAR bounds the explosive overpressure is an acceptable method of satisfying this criterion.

3.2.2 Compressed Gas Cylinder Impacts

1.

The impact of the cylinder or cylinder valve assembly with the cask systems must not damage the cask confinement (i.e., MPC) boundary and must not prevent removal of the MPC from the HI-TRAC transfer cask or the HI-STORM storage cask.

Holtec Report HI-2002512 Holtec Project 1073 page 9

4.0 Assumptions Material Detonations

1.

All evaluations of the effects of flammable liquid explosions are performed assuming that 100% of the liquid has been vaporized and mixed with air between its upper and lower flammability limits. The largest possible fuel amount will result in the largest incident overpressure, so it is conservative to assume 100% vaporization conditions.

2.

All elevation differences between the explosion hazard and the casks are neglected for material detonations. Any elevation differences would serve to increase the ground distance between the explosion hazards and the cask systems, thereby decreasing the resulting incident overpressure, so it is conservative the neglect elevation differences.

3.

No credit for partial shielding of casks systems by transport vehicles or other intervening structures is credited. Any energy absorbed by vehicles or other structures would reduce the severity of the overpressure incident on the cask systems, so it is conservative to neglect them.

4.

Gasoline-powered vehicles are prohibited from entering the ISFSI or approaching within fifty feet of a loaded cask system during storage or onsite transport and handling. This restriction ensures that the separation distance between a gasoline explosion and the cask system SSCs is sufficient to prevent blast damage.

5.

Combustible materials are not permitted within the ISFSI. This assumption is in accordance with Section 6.2.7.2 of the PG&E specification [2].

Compressed Gas Cylinder Impacts

6.

To determine the effects of catastrophic cylinder ruptures on the DCPP ISFSI cask systems, it is postulated that high-pressure compressed gas cylinders fail such that the valve assemblies break off. This failure mode would create an approximately 2-inch diameter hole in one end of the cylinder, and the escaping compressed gas would impart a large acceleration to the cylinder body and the valve assembly. This scenario represents the most likely failure mode and, therefore, represents the highest actual risk.

7.

The maximum velocity of all damaged gas cylinders and valve assemblies is calculated in the absence of aerodynamic drag forces. Any aerodynamic drag would only resist the acceleration of the cylinder or valve assembly, so it is conservative to neglect aerodynamic drag.

8.

The maximum velocity of all damaged gas cylinders and valve assemblies is calculated in the absence of atmospheric wind. Normal atmospheric wind velocities would be negligible in comparison with the expected cylinder and valve assembly velocities, so it is acceptable to neglect atmospheric wind.

Holtec Report HI-2002512 Holtec Project 1073 page 10

9.

The maximum velocity of all damaged gas cylinders and valve assemblies is calculated without including any elevation differences between the cylinders and the casks. Due to the expected short duration required for the venting compressed gas to accelerate a cylinder or valve assembly to high velocity and the relatively low gravitational acceleration, any elevation differences would result in negligible velocity differences.

10.

The maximum velocity of all damaged gas cylinders is calculated using bounding (1.0) discharge coefficients. Maximizing the discharge coefficient will maximize the thrust force and resultant acceleration, so it is conservative to use bounding discharge coefficients.

11.

The maximum velocity of all damaged gas cylinders is calculated assuming the cylinder motion is aligned with the longitudinal axis of the cylinder. Any skew of the thrust vector away from the cylinder axis would result in an arcing or tumbling cylinder trajectory that would consume a portion of the available compressed gas potential energy. Any reduction of the available potential energy that is converted into linear velocity would reduce the eventual maximum velocity, so it is conservative to align the thrust vector with the cylinder axis.

12.

Impact of the compressed gas cylinders and valve assemblies with the cask system SSCs occurs coincident with the maximum cylinder or valve assembly velocity. Maximizing the impact velocity will maximize the momentum and kinetic energy of the cylinder or valve assembly, so it is conservative to use the maximum velocity.

HI-STORM or HI-TRAC IE3 Standard acetylene bottle being transported past the ISFSI.

HI-STORM or HI-TRAC TEl Three fuel tanks (250 gal. of propane, 2000 gal. of #2 diesel HI-TRAC fuel and 3000 gal. of gasoline), approximately 1200 feet from the transport route to the ISFSI.

TE2 Unit 2 main bank transformers (13,000 gal. of mineral oil each),

HI-TRAC approximately 160 feet from the transport route to the ISFSI.

TE3 Compressed gas cylinders inside the reactor controlled area HI-STORM or (RCA) and near the RCA south gate.

HI-TRAC Each of these postulated hazards is evaluated, using the methodology presented in Section 2.1, to determine its actual explosive potential in the following subsections.

6.1.1 Evaluation of Hazard IEl The motor fuels that may be encountered in these vehicles include diesel fuel and gasoline.

MSDS sheets for these two materials are included in Appendix C.

Diesel fuel has a flash point of 125 'F. The explosive properties are listed as "Not Applicable" on the MSDS. As the flash point is greater than 85 'F (Section 3.1, criterion 1) and the explosion rating is, basically, none (Section 3.1, criterion 2) a diesel fuel explosion does not present a real explosion hazard.

Gasoline has a flash point of -40 'F. The explosive properties are listed as "Not Applicable" on the MSDS. As the flash point is less than 85 'F (Section 3.1, criterion 1) a gasoline explosion does present a real explosion hazard and must be evaluated to determine its effects.

Holtec Report HI-2002512 Holtec Project 1073 page 13

6.1.2 Evaluation of Hazard IE2 Propane is stored and transported as a liquefied compressed (-125 psia) gas. An MSDS sheet for this material is included in Appendix C.

Liquefied propane rapidly vaporizes at atmospheric pressure (-15 psia), so the flash point can be taken approximately equal to the boiling point (-43.5 'F). As stated on the MSDS, propane "poses an immediate...explosion hazard when mixed with air at concentrations exceeding 2.1%." As the flash point is less than 85 'F (Section 3.1, criterion 1) and the explosion rating is positive for explosion (Section 3.1, criterion 2), a propane explosion does present a real explosion hazard and must be evaluated to determine its effects.

The impact of a propane bottle on a cask resulting from explosive decompression of the contents of the bottle is bounded by hazard TE3, discussed below.

6.1.3 Evaluation of Hazard IE3 Acetylene is stored and transported as a gas dissolved in acetone under pressure. An MSDS sheet for this material is included in Appendix C.

Acetylene rapidly vaporizes at atmospheric pressure, so the flash point can be taken approximately equal to the boiling point (-103.4 'F). As stated on the MSDS, acetylene "poses an immediate.. explosive hazard when concentrations exceed 2.5%." As the flash point is less than 85°F (Section 3.1, criterion 1) and the explosion rating is positive for explosion (Section 3.1, criterion 2), an acetylene explosion does present a real explosion hazard and must be evaluated to determine its effects.

The impact of an acetylene bottle on a cask resulting from explosive decompression of the contents of the bottle is bounded by hazard TE3, discussed below.

6.1.4 Evaluation of Hazard TEl The three fuel tanks are close enough to each other that the explosion of one tank could result in the rupture of the other two. As such, all three tanks are postulated as a single explosion hazard.

MSDS sheets for the three materials are included in Appendix C.

As described in Subsections 6.1.1 and 6.1.2, propane and gasoline present a real explosion hazards but diesel fuel, as a result of its high flash point, does not. While the rupture and subsequent detonation of the propane or gasoline tank could rupture the diesel fuel tank, the resulting spilled diesel fuel could burn but not detonate. As detonation of the diesel fuel would not occur, the diesel will not contribute to any incident explosive overpressure.

Based on this evaluation, the near-simultaneous explosion of the propane and gasoline tanks presents a real explosion hazard and must be evaluated. The explosion of the diesel fuel tank does not, however, represent a real explosion hazard and is therefore not evaluated further.

Holtec Report HI-2002512 Holtec Project 1073 page 14

6.1.5 Evaluation of Hazard TE2 The mineral oil in the transformers serves as a transformer coolant. An MSDS sheet for this material is included in Appendix C.

Mineral oil has a flash point of 275 'F. As stated on the MSDS, mineral oil is "not considered to be an explosion hazard." As the flash point is greater than 85 TF (Section 3.1, criterion 1) and the explosion rating is, basically, none (Section 3.1, criterion 2) a mineral oil explosion does not present a real explosion hazard.

6.1.6 Evaluation of Hazard TE3 This postulated hazard does not involve the detonation of any material, but rather the explosive decompression of a confined, high-pressure gas. The postulated effect of this sudden, uncontrolled decompression is the acceleration of the cylinder, which could then impact cask system SSCs. As a consequence of the nature of this postulated hazard, this event is deemed to present a real explosion hazard and must be evaluated.

6.2 Evaluation of Explosion Effects The screening evaluation presented in the previous section identified postulated hazards IE1, IE2, IE3, TEl and TE3 as real explosion hazards that must be evaluated to determine their effects on cask system SSCs. Hazards IE1, IE2, IE3 and TEl involve the detonation of spilled hydrocarbon vapor clouds and are evaluated in Subsection 6.2.1. Hazard TE3 involves the explosive decompression of ruptured gas cylinders and is evaluated in Subsection 6.2.2.

6.2.1 Material Detonations Applying the methodology presented in Subsection 2.2.1, the incident explosive overpressure is calculated for each of the identified real explosion hazards. The evaluated scenarios are summarized here:

1.

IE1 - The fuel tank of an onsite, gas-powered vehicle is ruptured, spilling the entire contents. All the spilled gasoline vaporizes and mixes with air and the resulting vapor cloud subsequently detonates. Gasoline-powered vehicles are excluded from actually entering the ISFSI, so the minimum distance between the explosion and the cask system SSCs is the distance between the ISFSI pads and the security fence.

2.

IE2 - A propane bottle being transported past the ISFSI is ruptured, releasing the confined gas. The released propane mixes with air and the resulting vapor cloud subsequently detonates. Combustible materials are not permitted within the ISFSI, so the minimum distance between the explosion and the cask system SSCs is the distance between the ISFSI pads and the security fence.

3.

IE3 - An acetylene bottle being transported past the ISFSI is ruptured, releasing the confined gas. The released acetylene mixes with air and the resulting vapor cloud Holtec Report HI-2002512 Holtec Project 1073 page 15

subsequently detonates. Combustible materials are not permitted within the ISFSI, so the minimum distance between the explosion and the cask system SSCs is the distance between the ISFSI pads and the security fence.

4.

TEl - The propane and gasoline tanks along the main plant road are ruptured, releasing all the confined propane and gasoline. All the spilled gasoline vaporizes and both the propane and vaporized gasoline mix with air and the resulting vapor cloud subsequently detonates. The minimum distance between the explosion and the transport path to the ISFSI is approximately 1,200 feet [2].

These calculations are included in Appendix A.

6.2.2 Compressed Gas Cylinder Impacts Applying the methodology presented in Subsection 2.2.2, the maximum cylinder and valve assembly velocities are calculated for this real explosion hazard. The evaluated scenario is:

1.

TE3 - Cylinders containing gas under high-pressure are damaged such that the valve assembly located at the top of the cylinder breaks off. Expansion of the high-pressure gases out of the holes in the cylinders accelerates the cylinders or the valve assemblies toward the cask systems, resulting in eventual impacts.

These calculations are included in Appendix B.

7.0 Results and Conclusions 7.1 Evaluation of Explosion Potential As described previously (Section 6.1), this screening evaluation identified postulated hazards IEl, IE2, IE3, TEl and TE3 as real explosion hazards that must be evaluated to determine their effects on cask system SSCs. The following table presents a summary of the screening evaluation results for all six postulated hazards.

7.2 Evaluation of Explosion Effects 7.2.1 Material Detonations As described in Subsection 6.2.1, the incident explosive overpressure on cask system SSCs have been calculated in Appendix A. The following table presents a summary of the calculations and corresponding results.

In Section 3.4.7.2 of the HI-STORM FSAR [8, 9], the HI-STORM is evaluated under a postulated 10 psi overpressure for a duration of one second and is shown to perform satisfactorily. As the already evaluated overpressure exceeds those Holtec Report HI-2002512 Holtec Project 1073 page 17 I

calculated in Appendix A, it is concluded that the HI-STORM FSAR bounds the DCPP ISFSI explosion hazards, which subsequently do not adversely affect the HI-STORM system.

As presented in Section 6.1, hazards IE1, IE2, IE3 and TEl could all affect the I-II-TRAC transfer casks proposed for use at the DCPP ISFSI. The most severe accident involving the HI TRAC that already evaluated in the HI-STORM FSAR [8, 9] is the HI-TRAC handling accident, which consists of a 45-g deceleration during a postulated cask side drop. During this event and crediting HI-TRAC self-weight only (i.e., neglecting MPC weight), the HI-TRAC shell is exposed to a lateral force of at least 7.2 x106 pounds. Applied evenly over the projected area of the side of the HI-TRAC, this load corresponds to a minimum pressure of approximately 384 psi.

As the HI-TRAC has already been evaluated under a loading condition that far exceeds the overpressures calculated in Appendix A, and shown to perform satisfactorily, it is concluded that these DCPP ISFSI and transport route explosion hazards do not adversely affect the HI-TRAC transfer cask.

7.2.2 Compressed Gas Cylinder Impacts As described in Subsection 6.2.2, the maximum velocities of postulated bounding high-pressure gas cylinders and cylinder valve assemblies, following catastrophic valve assembly failures, have been calculated in Appendix B. The following table presents a summary of the calculations and corresponding results.

While the center portion of the HI-TRAC top lid is open, allowing direct access to the MPC lid inside, this opening is always protected from a missile impact by the body of the transporter. Even if the presence of the transporter is neglected, the 10-inch thickness of the MPC lid [13] precludes significant damage from the cylinder and valve assembly missiles.

The maximum calculated penetrations for all cylinders and valve assemblies is less than the minimum steel thickness of the HI-TRAC transfer cask, so it is concluded that the MPC will not Holtec Report HI-2002512 Holtec Project 1073 page 18

be damaged and that this DCPP explosion hazard does not adversely affect the HI-TRAC transfer cask.

The protective body of a HI-STORM 100S storage cask is composed of a 0.75-inch outer shell, a 27.25-inch concrete radial shield and a 1.25-inch inner shell [14]. Even if the concrete were completely neglected, a cylinder or valve assembly missile would have to penetrate over 2 inches of steel before it could impact the MPC. The air inlet and outlet ducts are located axially below and above the MPC, respectively, so a missile could not pass through a duct and impact the MPC. The maximum calculated penetrations for all cylinders and valve assemblies is less than the steel thickness of a HI-STORM 100S storage cask inner and outer shells, so it is concluded that the MPC will not be damaged and that this DCPP explosion hazard does not adversely affect the HI-STORM storage cask.

FLAMMABLE RANGE:

Not applicable 581-F (305°C) 2.5% - 81%

EXTINGUISHING MEDIA: Carbon Dioxide, Dry Chemical, Water.

SPECIAL FIRE FIGHTING INSTRUCTIONS: Shut off source of acetylene if possible. Extinguish fire only if flow can be stopped. Keep adjacent cylinders cool by spraying large amounts of water until the fire burns itself out and the cylinders are cool. If a flame is extinguished and acetylene continues to escape, an explosive re-ignition could occur.

UNUSUAL FIRE AND EXPLOSION HAZARDS: Excessive heat or fire will cause fusible metal pressure relief device to melt allowing acetylene to escape. Cylinders may rupture violently if sidewalls are exposed to direct flame impingement.

HAZARDOUS COMBUSTION PRODUCTS: Carbon monoxide, carbon dioxide.

SECTION 6. ACCIDENTAL RELEASE MEASURES STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Evacuate immediate area.

Eliminate any possible sources of ignition, and provide maximum explosion-proof ventilation. Shut off source of acetylene, if possible. Isolate any leaking cylinder. If leaking from cylinder, valve, or fusible metal pressure relief device, contact your supplier.

SECTION 7. HANDLING AND STORAGE STORAGE: Store and use with adequate ventilation. Cylinders should be separated from oxygen and other oxidizers by a minimum distance of 20 ft. or by a barricade of non-combustible material at least 5 ft. high having a fire resistance rating of at least 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Storage in excess of 2,500 cubic feet. is prohibited in buildings with other occupancies. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling or being knocked over. Post "No Smoking Or Open Flames" signs in the storage or use areas. There should be no sources of ignition. All electrical equipment should be explosion-proof in the storage areas. Storage areas must meet National Electric Codes for class 1 MSDS #1001 ACETYLENE Page 2 of 5 Pub #310-813

hazardous areas. Do not allow storage temperature to exceed 125 °F(52 °C). Full and empty cylinders should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for a long periods of time.

HANDLING: Protect cylinders from physical damage; do not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement. All acetylene piped systems and associated equipment must be grounded. Electrical equipment should be non-sparking or explosion-proof. Never use copper piping for acetylene service, only steel or wrought iron pipe should be used. An acetylene cylinder valve should be opened the minimum amount required to deliver acceptable flow so that it can be closed as quickly as possible in an emergency situation. Do not open acetylene cylinder valves more than one and one-half turns. Never use acetylene in excess of 15 psig pressure. Acetylene cylinders are heavier than other cylinders because they are packed with a porous filler material and acetone. Leak check with soapy water; never use a flame. Never insert an object (e.g., wrench, screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve, causing a leak to occur. Use an adjustable strap wrench to remove over-tight or rusted caps. Never strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit. Use the proper CGA connections, DO NOT USE ADAPTERS.

SPECIAL PRECAUTIONS: Use piping and equipment adequately designed to withstand pressures to be encountered. Use a check valve or other protective apparatus in any line or piping from the cylinder to prevent reverse flow.

E SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION ENGINEERING CONTROLS:

VENTILATION: Provide adequate natural or explosion-proof ventilation to ensure acetylene does not reach its lower flammable limit of 2.5%.

RESPIRATORY PROTECTION:

Emergency Use: Air supplied respirators are required in oxygen-deficient atmospheres (air purifying respirators will not function). Before entering area you must check for flammable or oxygen deficient atmospheres.

SKIN PROTECTION: Work gloves are recommended when handling cylinders.

EYE PROTECTION: Safety glasses are recommended when handling cylinders.

OTHER PROTECTIVE EQUIPMENT: Safety shoes recommended when handling containers.

--- Based on testing of similar products and/or the components.

OTHER ACUTE TOXICITY DATA: Inhalation of vapors/mists may cause respiratory system irritation.

HAZARDS OF COMBUSTION PRODUCTS:

Exposure to high concentrations of carbon monoxide can cause loss of consciousness, heart damage, brain damage and death.

Exposure to high concentrations of carbon dioxide can cause simple asphyxiation by displacing oxygen.

May be harmful or fatal if swallowed due to aspiration pneumonitis.

OTHER TOXICOLOGY DATA--

Gasoline and Refinery Streams:

Studies conducted by the American Petroleum Institute examined a reference unleaded gasoline for mutagenic, teratogenic and sensitization potential; no evidence of these hazards was found.

However, isolated constituents of gasoline may display these or other potential hazards in laboratory tests.

There were no significant adverse effects in three-month subchronic inhalation studies in rats or monkeys, or in a two-year skin cancer study in mice.

Studies with laboratory animals have shown that gasoline vapors administered at high concentrations over a prolonged period of time caused kidney damage and kidney cancer in male rats

and liver cancer in female mice.

The kidney tumors resulted from formation of a compound unique to male rats and is not considered relevant to humans.

The relationship of liver cancer in mice to humans is not known.

Studies carried out by Mobil's Environmental and Health Sciences Laboratory on some of the major refinery streams from which gasoline is formulated support the results of the API studies.

There was no evidence of significant adverse systemic or reproductive effects for light catalytic cracked naphthas and reformed naphthas.

Components:

Gasoline consists of a complex blend of petroleum/processing derived paraffinic, olefinic, naphthenic and aromatic hydrocarbons which include up to 5% benzene (with 1-2% typical in the U.S.),

n-hexane, mixed xylenes, toluene, ethylbenzene and trimethyl benzene.

Repeated exposures to low levels of benzene have been reported to result in blood abnormalities including anemia and, in rare cases, leukemia in both animals and humans.

Prolonged exposure to n-hexane. may result in nervous system damage, including numbness of the extremities and, in extreme cases, paralysis.

The adverse effects associated with these components have not been observed in studies with gasoline or the refinery streams from which it is formulated.

Generally, human exposures to gasoline vapors are considerably less than those used in the animal toxicity studies.

As far as scientists know, low level or infrequent exposures to gasoline vapor are unlikely to be associated with cancer or other serious diseases in humans.

Methyl Tertiary Butyl Ether (MTBE) was tested for carcinogenicity, neurotoxicity, chronic, reproductive, and developmental toxicity.

The NOAEL for all end points evaluated in three animal species was 400 ppm or greater.

An increase in kidney tumors/damage and liver tumors was observed in animals exposed to high concentrations of MTBE.

Some embryo/fetal toxicity and birth defects were observed in the offspring of pregnant mice exposed to maternally toxic doses of

MTBE, however the offspring of exposed pregnant rabbits were unaffected.

The significance of the animal findings at high exposures are not believed to be directly related to potential human health hazards in the workplace.

-ACGIH Threshold Limit Value (TLV):

5 mg/m3 (TWA) 10 mg/m3 (STEL)

(las sampled by method that does not collect vapor)

( 1Refers to airborne mist of mineral oil)

Ventilation System:

A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):

If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator (NIOSH type P95 or R95 filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type P100 or R100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. Please note that N filters are not recommended for this material. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection:

Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.

CAS NUMBER: 74-98-6 EXPOSURE LIMITS:

OSHA: PEL-TWA = 1000 ppm ACGIH: TWA/TLV = 2500 ppm NIOSH: IDLH = 2100 ppm (10%LEL)

SECTION 3. HAZARD IDENTIFICATION EMERGENCY OVERVIEW Propane is a flammable, odorless, colorless liquefied compressed gas packaged in cylinders under its own vapor pressure of 124.9 psia at 70 OF. It poses an immediate fire and explosion hazard when mixed with air at concentrations exceeding 2.1%. High concentrations that can cause rapid suffocation are above the lower flammable limit and must not be entered. Propane is heavier then air and may collect in low areas or travel along the ground where there may be an ignition source present. Direct contact with liquid can cause frostbite.

EMERGENCY TELEPHONE NUMBERS (800) 523 - 9374 Continental U.S., Canada and Puerto Rico (610) 481 - 7711 Other locations ACUTE POTENTIAL HEALTH EFFECTS:

ROUTES OF EXPOSURE:

EYE CONTACT: Contact with liquid (or rapidly expanding gas) may cause irritation and frostbite.

INGESTION: Ingestion of Propane is not a likely route of industrial exposure.

INHALATION: Propane is nontoxic, but high concentrations may have an anesthetic effect. It can also reduce the amount of oxygen in the air necessary to support life. Exposure to oxygen-deficient atmospheres (less than 19.5%) may produce dizziness, nausea, vomiting, loss of consciousness, and death. At very low oxygen concentrations (less than 12%) unconsciousness and death may rapidly occur without warning. It should be noted that before suffocation could occur, the lower flammable limit for Propane in air will be exceeded; causing both an oxygen deficient and an explosive atmosphere.

SKIN CONTACT: Contact with liquid (or rapidly expanding gas) can cause irritation and frostbite.

Propane MSDS # 1061 Pub # 310-827 Page I of 5

POTENTIAL HEALTH EFFECTS OF REPEATED EXPOSURE:

ROUTE OF ENTRY: Skin contact SYMPTOMS: Repeated or prolonged contact may cause dermatitis.

TARGET ORGANS: Skin MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: May aggravate dermatitis.

CARCINOGENICITY: Propane is not listed as a carcinogen or potential carcinogen by NTP, IARC, or OSHA Subpart Z.

SECTION 4. FIRST AID MEASURES EYE CONTACT: If liquid propane comes in contact with eyes, flush eyes with plenty of lukewarm water for several minutes. Seek medical attention immediately.

INGESTION: Ingestion of Propane is not a likely route of industrial exposure.

INHALATION: Remove person to fresh air. If not breathing, administer artificial respiration. If breathing is difficult, administer oxygen. Obtain prompt medical attention.

SKIN CONTACT: If liquid Propane comes in contact with skin, remove contaminated clothing and flush with plenty of lukewarm water for several minutes. Seek medical attention immediately.

NOTES TO PHYSICIAN: Treatment of overexposure should be directed at the control of symptoms and the clinical condition.

IE SECTION 5. FIRE FIGHTING MEASURES FLASH POINT:

AUTOIGNITION:

FLAMMABLE RANGE:

Not applicable 842 -F (450 -C) 2.1% - 9.5%

EXTINGUISHING MEDIA: Carbon dioxide, dry chemical, water.

SPECIAL FIRE FIGHTING INSTRUCTIONS: Evacuate all personnel from area. If possible, without risk, shut off source of Propane, then fight fire according to types of materials burning. Extinguish fire only if gas flow can be stopped. This will avoid possible accumulation and re-ignition of a flammable gas mixture.

Keep adjacent cylinders cool by spraying with large amounts of water until the fire burns itself out. Self contained breathing apparatus (SCBA) may be required.

UNUSUAL FIRE AND EXPLOSION HAZARDS: Most cylinders are designed to vent contents when exposed to elevated temperatures. Pressure in a cylinder can build up due to heat and it may rupture if pressure relief devices should fail to function. Propane vapors are heavier than air and may travel to a source of ignition and flash back.

HAZARDOUS COMBUSTION PRODUCTS: Carbon monoxide SECTION 6. ACCIDENTAL RELEASE MEASURES STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: Evacuate immediate area. Eliminate any possible sources of ignition, and provide maximum explosion-proof ventilation. Use a flammable gas meter (explosimeter) calibrated for Propane to monitor concentration. Never enter an area where the Propane concentration is greater than 0.42% (which is 20% of the lower flammable limit). Am immediate fire and explosion hazard exists when atmospheric Propane concentration exceeds 2.1%. Use appropriate protective equipment (SCBA and fire resistant suit). Shut off source of leak if possible. Isolate any leaking cylinder. If leak is from container, pressure relief device or its valve, contact your supplier. If the leak is in the user's system, close the cylinder valve, safely vent the pressure, and purge with an inert gas before attempting repairs.

SECTION 7. HANDLING AND STORAGE STORAGE: Store cylinders in a well-ventilated, secure area, protected from the weather. Cylinders should be stored upright with valve outlet seals and valve protection caps in place. There should be no sources of ignition. All electrical equipment should be explosion-proof in the storage areas. Storage areas must meet National Electrical Codes for class 1 hazardous areas. Flammable storage areas must be separated from oxygen and other oxidizers by a minimum distance of 20 ft. or by a barrier of non-combustible material at least 5 ft. high having a fire resistance rating of at least 1/2 hour. Post "No Smoking or Open Flames" signs in MSDS # 1061 Pub# 310-827 Page 2 of 5 Propane

the storage or use areas. Do not allow storage temperature to exceed 125 OF (52 0C). Storage should be away from heavily traveled areas and emergency exits. Full and empty cylinders should be segregated.

Use a first-in first-out inventory system to prevent full containers from being stored for long periods of time.

HANDLING: Do not drag, roll, slide or drop cylinder. Use a suitable hand truck designed for cylinder movement. Never attempt to lift a cylinder by its cap. Secure cylinders at all times while in use. Use a pressure reducing regulator or separate control valve to safely discharge gas from cylinder. Use a check valve to prevent reverse flow into cylinder. Never apply flame or localized heat directly to any part of the cylinder. Do not allow any part of the cylinder to exceed 125 IF (52 0C). Once cylinder has been connected to properly purged and inerted process, open cylinder valve slowly and carefully. If user experiences any difficulty operating cylinder valve, discontinue use and contact supplier. Never insert an object (e.g.,

wrench, screwdriver, etc.) into valve cap openings. Doing so may damage valve causing a leak to occur.

Use an adjustable strap-wrench to remove over-tight or rusted caps. All piped systems and associated equipment must be grounded. Electrical equipment should be non-sparking or explosion-proof.

SPECIAL PRECAUTIONS: Always store and handle compressed gas cylinders in accordance with Compressed Gas Association, Inc. (telephone 703-412-0900) pamphlet CGA P-1, Safe Handling of Compressed Gases in Containers. Local regulations may require specific equipment for storage or use.

SECTION 8. EXPOSURE CONTROL / PERSONAL PROTECTION ENGINEERING CONTROLS:

VENTILATION: Provide adequate ventilation and / or local exhaust to prevent accumulation of gas concentrations above the TWA of 1000 ppm.

RESPIRATORY PROTECTION:

Emergency Use: SCBA or positive pressure air line with mask should be used in areas where concentration is above the TWA, however do not enter areas where concentration is greater than 0.42% (20% of the LEL).

EYE PROTECTION: Safety glasses for handling cylinders. Chemical goggles with full faceshield for connecting or disconnecting cylinders.

SKIN PROTECTION: Leather gloves for handling cylinders. Neoprene gloves during use of product. Fire resistant suit and gloves in emergency situations.

OTHER PROTECTIVE EQUIPMENT: Safety shoes are recommended when handling cylinders.

SECTION 9. PHYSICAL AND CHEMICAL PROPERTIES APPEARANCE, ODOR AND STATE: At room temperature and atmospheric pressure, Propane is a colorless, odorless, flammable gas. It is shipped as a liquefied gas under its own vapor pressure.

PREFACE This work product has been labeled a safety-significant document in Holtec's QA System. In order to gain acceptance as a safety significant document in the company's quality assurance system, this document is required to undergo a prescribed review and concurrence process that requires the preparer and reviewer(s) of the document to answer a long list of questions crafted to ensure that the document has been purged of all errors of any material significance. A record of the review and verification activities is maintained in electronic form within the company's network to enable future retrieval and recapitulation of the programmatic acceptance process leading to the acceptance and release of this document under the company's QA system. Among the numerous requirements that a document of this genre must fulfill to muster approval within the company's QA program are:

The preparer(s) and reviewer(s) are technically qualified to perform their activities per the applicable Holtec Quality Procedure (HQP).

The input information utilized in the work effort must be drawn from referenced sources.

Any assumed input data is so identified.

All significant assumptions, as applicable, are stated.

The analysis methodology, if utilized, is consistent with the physics of the problem.

0 Any computer code and its specific versions that may be used in this work has been formally admitted for use within the company's QA system.

0 The format and content of the document is in accordance with the applicable Holtec quality procedure.

The material content of this document is understandable to a reader with the requisite academic training and experience in the underlying technical disciplines.

Once a safety significant document produced under the company's QA System completes its review and certification cycle, it should be free of any materially significant error and should not require a revision unless its scope of treatment needs to be altered. Except for regulatory interface documents (i.e., those that are submitted to the NRC in support of a license amendment and request), revisions to Holtec safety-significant documents to amend grammar, to improve diction, or to add trivial calculations are made only if such editorial changes are warranted to prevent erroneous conclusions from being inferred by the reader. In other words, the focus in the preparation of this document is to ensure accuracy of the technical content rather than the cosmetics of presentation.

This calculation package has been prepared pursuant to the provisions of Holtec Quality Procedures HQP 3.0 and 3.2, which require that all analyses utilized in support of the design of a safety-related or important-to-safety structure, component, or system be fully documented such that the analyses can be reproduced at any time in the future by a specialist trained in the Holtec Report HI-2002559 Holtec Project 1073 page 1

discipline(s) involved. HQP 3.2 sets down a format for the content and organization of calculation packages that are intended to create a document that is complete in terms of the exhaustiveness of content. The calculation packages, however, lack the narrational smoothness of a technical report, and are not intended to serve as a technical report.

Because of its function as a repository of all analyses performed on the subject of its scope, this document will require a revision only if an error is discovered in the computations or the equipment design is modified. Additional analyses in the future may be added as numbered supplements to this package. Each time a supplement is added or the existing material is revised, the revision status of this package is advanced to the next number and the table of contents is amended. Calculation packages are Holtec proprietary documents. They are shared with a client only under strict controls on their use and dissemination.

This calculation package will be saved as a permanent record under the company's QA System.

Holtec Report HI-2002559 Holtec Project 1073 page 2

1 1.0 Introduction Section 72.122 of the Code of Federal Regulations [1] defines the requirements for licensing basis evaluations of environmental conditions and natural phenomena at a proposed independent spent fuel storage installation (ISFSI). Sections 6.2.6 and 6.2.9.1 of the Pacific Gas and Electric (PG&E) specification [2] for the ISFSI at the Diablo Canyon Power Plant (DCPP) postulates two severe electrical hazards (a lightning strike and 500kV transmission line breaks) that could possibly affect proposed ISFSI structures, systems and components (SSCs) that are important-to safety. This report is issued to document the analyses performed to quantify the potential effects, if any, of the postulated electrical hazards on the storage and transfer casks that will be used at the DCPP ISFSI.

The following sections of this document present the computational methods and input data used to perform the explosion hazard evaluations (Sections 2.0, 4.0 and 5.0), the acceptance criteria applied to the computational results (Section 3.0), the evaluations themselves (Section 6.0), and the numeric calculation results and final conclusions.

I Holtec Report HI-2002559 Holtec Project 1073 page 3

2.0 Methodology The postulated lightning strike presents as a short duration, high current electric flow. The current will flow through the impacted cask SSC and dissipate to the ground. All Holtec casks are encased in painted carbon steel, so the current will flow through the outer conductive shell.

Localized paint damage will likely occur where the current enters and exits the outer shell, and the resistance to current flow in the material will cause a heat generation within the shell that must be dissipated.

The power of a direct current flow through a resistive material (Pdc) can be calculated using the following, familiar formula [3]:

pd' = I 2R (2-1) where I is the current and R is the resistance of the conduction path. The resistance is calculated from the conductor length, cross-sectional area and resistivity, which is a property of the conducting material. The resistance is calculated as [4]:

R = pxL (2-2)

A where p is the resistivity, L is the conductor length and A is the conductor cross-sectional area.

To obtain the electrical energy generated during a current flow of finite duration, the power is multiplied by the duration. The energy of a direct current flow through a resistive material (Edc) can be calculated using the following formula:

Edc = I 2At R (2-3) where At is the duration of the current flow.

The lightning strike results in a finite-duration current flow. Recognizing that the resistance is independent of the current magnitude, Equation 2-3 can be modified to encompass events involving step changes of the current at discrete time points. The resulting equation, shown here for a two-part current flow event with a single step change of the current, is:

Edc = (I 2Ati + I 2 At2)R (2-4)

Once the energy is determined using Equation 2-4, the thermal effects (i.e., the temperature rise due to resistance heating) can be calculated from an energy balance using:

Edc =mxCpxAT (2-5) where m is the mass of the conductor, Cp is the specific heat capacity of the conductor material and AT is the temperature rise of the conductor. Equation 2-5 can be rearranged to solve for the temperature rise, yielding:

Holtec Report HI-2002559 Holtec Project 1073 page 4

AT -

E dc mxCp (2-6)

It should be noted that this methodology has been used to evaluate the effects of lightning strikes on Holtec' s approved HI-STAR 100 System (NRC Docket 72-1008).

The postulated 500kV transmission line break presents as a time-varying, high-voltage and high current electric flow. As the falling transmission line approaches the cask, a high-voltage arc will form from the line to the cask. The voltage of this arc will fall rapidly as the arc current rises.

Once the line contacts the cask, the fault voltage will be relatively low and the fault current relatively high, compared with the beginning of the arc. As with the lightning strike event, the current will flow through the cask outer conductive shell and dissipate to the ground, resulting in heat generation.

Because of the time-varying voltage during the arc and the relatively long (compared to the lightning strike) duration of this event, the power of the arc and subsequent current flows is calculated using a modified formulation of Equation 2-1. Recognizing that voltage (V) is equal to current multiplied by resistance [3] and the time-varying nature of the voltage and current during the arc, the power equation can be recast as:

P(t) = V(t) x I(t)

(2-7) where P(t) is the time-varying power, V(t) is the time-varying voltage and I(t) is the time-varying current. This equation can be integrated over the duration of the event to obtain the energy generated (E ge,) as:

3.0 Acceptance Criteria No acceptance criteria are applied in this report. A discussion of the acceptability of the calculated results is provided in Section 8.2.8 of the DCPP ISFSI SAR.

Holtec Report HI-2002559 Holtec Project 1073 page 6

4.0 Assumptions

1.

All evaluations of the effects of electric resistance heating are performed assuming that all current flows through the outermost shell of the affected cask. Limiting the current flow to a single conduction path will maximize the heat generation, conservatively maximizing the resultant thermal effects.

2.

Current penetration into only the outer 0.01-inch depth of the cask outer shell is credited in the resistance heat calculations. This will conservatively decrease the conductor cross sectional area, increasing the resistance and resulting heat generation, and the conductor thermal inertia, increasing the resultant temperature rise.

3.

The resistivity of the carbon steel cask outer shells is conservatively estimated by increasing the resistivity of iron by 20%, to account for the presence of small amounts of higher-resistivity elements in the alloy. This simplification is necessary because specific resistivity data is not available for structural steels, as they are not typically used in electrical components. A comparison of the estimated resistivity value with the limited available steel data demonstrates the conservatism of this assumption.

4.

The heat of sublimation of carbon steel is assumed equal to that of elemental iron. The majority component of carbon steel is iron, so there should be little difference between the two materials.

1.0 Introduction Section 72.122 of the Code of Federal Regulations [1] defines the requirements for licensing basis evaluations of fire events at a proposed independent spent fuel storage installation (ISFSI).

Section 6.2.7 of the Pacific Gas and Electric (PG&E) specification [2] for an ISFSI at the Diablo Canyon Power Plant (DCPP) postulates a wild fire in the vegetation surrounding the ISFSI that could possibly affect proposed ISFSI structures, systems and components (SSCs) that are important-to-safety. This report is issued to document the analyses performed to quantify the effects of the postulated wild fires on the storage casks that will be used at the DCPP ISFSI.

The following sections of this document present the computational methods and input data used to perform the wild fire evaluations (Sections 2.0, 4.0 and 5.0), the acceptance criteria applied to the computational results (Section 3.0), the evaluations themselves and numeric results (Section 6.0), and the final conclusions (Section 7.0).

Holtec Report HI-2012615 Holtec Project 1073 page 2

2.0 Methodology 2.1 Heat Input to Cask from Onsite Transporter Fuel Tank Fire Previous analyses documented in the HI-STORM FSAR [3, 4] have been performed to evaluate the effects of an onsite transporter fuel tank fire on a HI-STORM storage cask. The amount of heat input to a cask during this design basis fire is determined by post-processing the existing transient finite-element thermal results to obtain the solution to the following equation:

Q, =mxCpxAT (2-1) where:

Qi,, is the total heat input during the fire m is the mass of the heated body Cp is the specific heat of the body AT is the bulk temperature change of the body As presented, Equation 2-1 is applicable to a homogeneous material. Because the casks are not homogeneous and the bulk temperature of the cask is not directly available, Equation 2-1 must be discretized to accommodate the nature of the discretized numeric models, as:

Q I

=V, xpx Cp x AT, (2-2) where:

Qm. is the total heat input during the fire n is an index, from 1 to the total number of elements V, is the volume of element n p9, is the density of element n Cp, is the specific heat of element n AT, is the temperature change of element n The temperature change (AT,) is the difference in temperature between the initial condition and the end of the fire duration.

2.2 Heat Input to Cask from Site-Specific Wild Fires For a fire that is not directly adjacent to a cask, the primary heat transfer mechanism will be thermal radiation. This is due to the high flame temperatures associated with fires and the fourth power relationship between the flame temperature and the radiation heat flux. Heat transferred via thermal radiation will be emitted equally in all directions.

As described in the assumptions in Section 4.0, no flammable materials are stored within the ISFSI and all areas within the ISFSI nuisance fence will be covered with either concrete or gravel. The ISFSI nuisance fence will be at least 50-feet from the nearest storage casks, so the postulated wild fires are of the type described above. The amount of heat input to a cask during Holtec Report HI-2012615 Holtec Project 1073 page 3

the postulated wild fires can, therefore, be very conservatively estimated by using the following relationship:

Qi,, = Q Fvie x E 8ck (2-3) where:

Qin is the total heat input during the fire Qfire is the total heat energy released during the fire Fvi,, is the fire-to-cask geometric view factor P is the ernissivity of the cask surfaces The fire-to-cask geometric view factor (Fview) can be estimated by modeling the cask as a cylinder and the fire as a concentric outer cylindrical wall of flame. The following set of equations [5], for concentric cylinders of unequal height, can be used to calculate the cask -to-fire view factor:

3.0 Acceptance Criteria The total heat input to a cask from each postulated site -specific wild fire must be less than that input from the design basis onsite transporter fuel tank fire accident evaluated in the HI -STORM FSAR [3, 4].

I Holtec Report HI -2012615 Holtec Project 1073 page 5

4.0 Assumptions

1.

The analyses of the heat input from a wild fire do not recognize any attempt at fire suppression. Any suppression actions would reduce the severity of the fire, so it is conservative to neglect them.

2.

It is assumed that all areas within the ISFSI nuisance fence are covered with either gravel or concrete. This assumption excludes the presence of any vegetation within the ISFSI boundary. This assumption is in accordance with the PG&E specification [2], which states "casks will be separated from such fires by the distance between the casks and the ISFSI perimeter."

3.

The minimum distance from the ISFSI nuisance fence to the edge of the ISFSI pad is assumed to be 50 feet. The actual distance, governed by shielding concerns, is expected to be greater than 50 feet. The use of the smaller separation distance will conservatively maximize the fire heat input to the casks.

4.

It is assumed that any wild fire that is more than 200 yards from the ISFSI will have no effect on the casks. The view angle from such a distant fire is less than 20, so the fire-to cask view factor will be negligible.

5.

The wild fire is modeled as a ring of fire completely surrounding a single cask. This conservatively neglects the blocking effect of any other casks or structures at the ISFSI. It is noted that, per the PG&E specification [2], "no flammable facilities are present near the north side of the ISFSI site." It is, therefore, impossible for any wild fire to completely surround the ISFSI.

6.

It is assumed that the entire heat energy of the wild fire released at the fireline is directed toward the ISFSI. This neglects the omni -directional behavior of thennal radiation heat transfer, conservatively maximizing the heat input to a cask.

7.

The fire-to-cask view factor is calculated assuming the fire-to-cask distance is the minimum separation distance throughout the wild fire duration. This conservatively maximizes the view factor and, consequently, the resulting heat input to the cask.

8.

Radiation scattering and absorption by atmospheric elements (i.e., air, dust, water vapor, etc.) is neglected. Inclusion of these effects would only reduce the amount of heat input to the cask, to their neglect is conservative.

5.0 Input Data 5.1 Heat Input to Cask from Onsite Transporter Fuel Tank Fire The heat input to a HI-STORM storage cask from the onsite transporter fuel tank fire is determined using Equation 2-2 and post-processing the results of the previously performed transient finite-element thermal evaluation. The following input data are required to determine the fire heat input:

Input Parameter Parameter Value Data Source Density of Carbon Steel 0.283 lb/in3 Reference 6 Heat Capacity of Carbon Steel 0.10 Btu/(lbxxF)

Reference 6 Density of Concrete 0.0822 lb/in3 Reference 6 Heat Capacity of Concrete 0.156 Btu/(lbxxF)

Reference 6 5.2 Heat Input to Cask from Site-Specific Wild Fires All input data necessary to perform these calculations are presented within the calculations themselves (Appendix B) and are not repeated here.

6.0 Calculations and Results 6.1 Heat Input to Cask from Onsite Transporter Fuel Tank Fire The heat input to a HI-STORM cask is determined using Equation 2-2, as described above in Section 2.1. Version 5.6 of the ANSYS finite-element computer program, QA validated by Holtec, is used to post -process the existing transient thermal results. The ANSYS output file from this post-processing is presented in Attachment A to this document. The following Holtec server directory listing shows the locations of all computer files used for this calculation:

Qi, = (16.303 x06 + 5.54412x106 )-(15.9553 x106 +4.34325x 106 )=1,548,570 Btu The two values in the first set of parenthesis (16.303 X106 and 5.54412x106 ) are the post-fire heat contents of the cask concrete and steel, respectively. The two values in the second set of parenthesis (15.9553x 106 and 4.34325x 106 ) are corresponding pre -fire heat contents.

6.2 Heat Input to Cask from Site -Specific Wild Fires Two separate wild fire scenarios are postulated for the DCPP ISFSI site. The first scenario is a wild fire that occurs without wind and the second is a wild fire that occurs with a 15 mph up hill wind. These two scenarios have different fireline intensities and velocities and different flame heights. For each scenario, the heat input to a HI -STORM cask is determined using Equation 2-3, as described above in Section 2.2, in Appendix B. The calculated results are:

Wild Fire Scenario Calculated Cask Heat Input No Wind 395,892 Btu 15 mph Wind 321,284 Btu Holtec Report 111 -2012615 Holtec Project 1073 page 8

7.0 Conclusions The heat input to the HI -STORM cask from the onsite transporter fire, calculated in Section 6.1, is greater than the heat input to the HI -STORM cask from either postulated wild fire scenario.

This result satisfies the acceptance criterion stipulated in Section 3.0, so it is concluded that the postulated site-specific wild fires will not adversely affect the HI-STORM storage casks at the DCPP ISFSI.
