3.0 INTRODUCTION

3.1 Ciarrent Studies As a result of , studies completed in October 1972, Crystal River

(

s

) No. 3 was designed to safely withstand a PMH which would produce

. a surge level of 29.6 feet above the mean low water (MLW) elevation I. of 88 feet. A more current study has been completed recently by

( Dames and Moore and the results are included in their report titled, " Report - Verifiqation Study of Dames and Moore's Hurricane s

} Storm Surge Model with Application to Crystal River Unit No. 3

  • Nuclear Plant - Crystal River Florida - for Florida Power Corporation"

\ dated July 13, 1973 hereinaf ter referred to as the Dames and Moore Report. The new report includes the PMH parameters along with substantiation and justification of the results if such a PMH should occur. Primary information includes a surge level of

, 29.4 feet above MLW elevation of 88 feet and a resulting "wavelsss"

)

surge to elevation 119.5 feet over ths top of the embankment whose design elevation is 118.5 feet. The hurricane would track from southwest to northeast.

3.2 AEC Questions

{ On March 12, 1973 the Atomic Energy Commission advised Florida Power Corporation that additional information was required t regarding the Probable Maximum Hurricane (PMH) surge level and the

, associated wave runup. This report therefore also addresses itself to the following questions which were presented in Enclosures (1) and (2) of the AEC letter. Questions 1 through 5(c) of Enclosure l.

4.0 PMH CONDITIONS AT PLANT 4.1 Storm Surae Level

ne maximum storm tide level provided by Dames and Moore is elevation 117.4 feet (MLW is at elevation 88.0 feet). This

( determination considered the topography of the site along the i

approach path and the critical section shown on Figure 1. The f' maximum storm tide level also considered a two-foot reduction due to tb effects of backwater storage resulting from the i .

i extensive flooding of the surrounding countryside some five hours prior to the peak of the surge hydrograph and runoff into peripheral areas not directly affected by the hurricane surge.

The site in this extreme circumstance becomes analogous to a small island in a rountain of water. The storm surge hydrograph

, is shown on Figure 4, and includes the combined effects of the hurricane surge and the astronomical tide.

4.2 Wave Action and Runup t

L 4.2.1 Figure 6 summarizes the relationships between the stillwater level, wind-generated wave height, breaking wave height and wave runup.

The maximum (highest 1 percent of the waves) and significant t

(average of the highest one-third) wave heights were determined

, by wind vectors normal to the coast along the traverse, and were

< i calculated using the storm surge computer output. Figure 5

( presents a summary of this analysis for wind-generated waves L. .

approaching the site. On Figure 6, the intersection of the breaking wave curve and the generated wave height curves show that with the highest 1 percent of the waves breaking, the s.

7 _l marinann height of the waves that can travel across the fill approaching the plant is 15.0 feet. With the average of the

' highest 33 percent (shown as Hs) of the waves breaking, the maximum height of the waves that can reach the protective embankment with-r out breaking is 13.9 feet.

s.

. 4.2.2 Maxi:num tidal setup will be produced by winds blowing onshore

! along a traverse normal to the offshore bottom contours.

i Consequently, the critical approach path for a hurricane was ,

from the southwest, tracking on a aortheasterly course. However, f the approach path of wave trains that will produce maximum runup at the site is along a north-south section with the waves approaching the plant from the south. This critical traverse of i the wave train is across a reach of natural ground about one

(

mile wide, then over 600 feet of compacted fill (elevation 98),

i and against an embankment slope (berm) rising to a top elevation of 118.5 feet, which protects the plant. This concept of i

! maximum wave action occurring perpendicular to the hurricane winds i was considered to be a conservative assumption for this already extremely severe condition.

i 4.2.3 The effects of breaking waves and wave runup on the embankment I

slope were evaluated from the model tests previously conducted at 4 - l, the University of Florida. Before performing the runup tests, e experiments were conducted to determine the most adverse test conditions (i.e., the combination of wave period and height which

. caused the maximum runup over the tidal range of interest). From

(

r^

8 these pre-test experiments and periodic checks during the tests, it was found that the maximum runup occurred with a 7rototype wave period of 5.4 seconds, and prototype wave amplitudes of 10 to 15 feet, the specific height depending on the test case.

The wave action testing was conducted at prototype tide levels from elevation 104 to 120 feet in two-foot increments. Unlike -

the spectrum of wind-generated waves, the model t;sts were conducted with waves essentially uniform in height.

4.2.4 Initial tests were conducted on a smooth slope embankment.

Subsequent tests simulated the runup effects against the stepped embankment. The test results indicated no overtopping of the

, j smooth slope below tide levels of 110 feet, with occasional overtopping starting at a tide level of 112 feet and becoming J

continuous above elevation 114. Tests on the stepped slope

, revealed no -overtopping below tide elevation 112 feet, slight I

i

. overtopping at 114, and more continuous overtopping above i

t elevation 116 feet. Pertinent results of the model tests are shown on Figures 2 and 3 and on Tables 1, 2 and 3.

4.2.5 The applicability of the model tests for the 29.4-foot surge level

.t is illustrated by Figure 3 and amplified by two letters from Dr. R. G. Dean dated April 3,1972, and April 11, 1973, contained in the Attachments. As- indicated by Figure 3, the median and s

maximum runup elevations occurring at a tide level of 117.4 feet are 122.5 and' 123.5, respectively on Profile 5, the profile

i. corresponding to the stepped slope that will be constructed at i

Crystal River Nuclear Station. The actual elevation of th i water '

overtopping embankment at elevation 118.5 will be somewhat less than the elevation of the runup on the test slope because with the limited slope height '(the steps above 118.5 used in the model I l

, do not exist in the actual design) the surging water will reach -

r elevation 118.5 and merely fall over on the embankment, r

6 4.2.6 For a slope of unlimited height, the maximum and median runup corresponding to the indicated stillwater hydrograph were developed ' ~

using Figure 3 and are shown on Figure 6. When the height of the

( wind-generated waves reaching the protective embankment becomes 1

10 to 15 feet (the range of wave heights found from the model tests to cause the greatest runup), the results of the model tests become applicable. Until that time, the wind-generated waves would produce less runup than indicated; the runup from the test results is therefore shown as a dotted line. Employing the~

s conservative assumption that the wave height in the model tests was

( the " maximum" generated wave height (i.e. , assucing that all of the waves attacking the embankment are " maximum" waves), Figure 6 shows that the model results become applicable at 23.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> af ter the center of the hurricane crosses the continental shelf. This 1 is also the time of maximum stillwater level.

I It is estimated that overtopping of the embankment by the maximum runup begins about hour 22.7 and continues until hour 24.2. For the reasons described, the elevation of the water overtopping' the

!_ edge of the actual embankment will be less than the runup i

.due to overtopping, is estimated to be one foot. At locations along the plant embankment that are not exposed to direct wave

t. attack, overtopping shou .d not occur. Water th'at does overtop the embankment on the windward side of the plant will drain off the embankment on the lee side.

t 5.0 VITAL EQUIPMENT AND ITS PROTECTION 5.1 Continuous Power Generation 5.1.1 Under any conditions, the equipment necessary for power generation is as follows:

r- 1. On-site diesel power generators, and their support equipment (fuel systems, cooling systems, switchgear).

2. Reactor decay heat removal equipment
a. Nuclear services closed cycle cooling system.

(

b. Decay heat removal system.
c. Decay heat closed cycle cooling system.
d. Decay heat ces water system.
e. Nuclear services sea water system.
3. Circulating water pumps.

, 4. Electric transmission facilities (switchyard).

5. Turbine-generator support equipment.

5.1.2 Power generation at sea levels above elevation 98 is not possible since the circulating water ramps, located at the intake canal, and the transmission facilities in the sw1; ayard will begin to flood.

5.1.3 The circulating water pumps begin to cavitate when the water level drops below elevation 81 feet; however these pumps do not m.

serve any equipment necessary to maintain the reactor in a safe

, condition.

5.2 Equipment Necessary for Safe Shutdown 5.2.1 Systems listed under items 1 and 2 Subaection 5.1.1 must remain s.

functional during storms of any degree of severity up to and including the PMH. Ability of this equipment to remain functional i

is assured by the facility design discussed herein.

t

, 5.2.2 On-site emergency power generation equipment is located within the main structure, and is protected from flooding by concrete i barriers. Fuel storage tanks are located underground, and are .

restrained against damage from their own bouyancy by hold down

straps and concrete anchor slabs. Tank vents are 'above postu-

, laced wave tops to prevent sea water from entering the tanks via s

the vent lines. Diesel engine cooling is provided by a self-j contained air radiator system within the structure.

t ,

4 r l 5.2.3 The nuclear services closed cycle cooling system, decay heat removal system, and decay heat closed cycle cooling system are located within the auxiliary building, which is protected from i

flooding by water-tight doors where necessary.

5.2.4 Pumps and heat exchangers serving the decay heat sea water and i

nuclear services sea water systems are also located within the protected auxiliary building. Sea water is admitted to the

s. pump sump chambers via two conduits connected to the intake structure at the intake canal. Although this intake structure will be inundated at the postulated hurricane sea levels , no active equipment necessary to maintain the reactor in a safe l , condition is located at the structure.

13 5.2.5 The sea water pumps located within the auxiliary building, take suction from a chamber designed for a static sea level of 140 feet, which is well. ia excess of the postulated hurricane sea levels.

These pumps require a minimum pump submergence level of elevation 70 feet, 10-1/2 inches (water surface elevation) for satisfactory i

operation. The increase in static pressure on pumps, piping, .

heat .exchangers, and other components in the sea water systems .

due to the increased pump suction pressure, are less than the design conditions for these components. '

s 5.2.6 The above equipment is powered by the emergency diesel generators.

In addition, if power should be lost, sump pumps can be operated from the emergency diesel generators, to dispose of any leakage, through water-tight door seals.

14 6.0 DETAILED FLOOD PROTECTION 6,1 Protective Assumptions I

6.1.1 Figure 8 indicates the locations of seals, water-tight doors,

, j concrete barriers'and walls which have been included in the l

design to protect access openings in the structure which may }

be subjected to flooding during the peak of the PMH (about 1.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />).

6.1.2 It should be noted that although the anticipated water level during the peak of the PMH is only to elevation 119.5 on the south decreasing to elevation 117.4 on the north, protection has -

been conservatively provided as though the maximum wave runup i

to elevation 123.5 exists over the entire south embankment.

6.2 Component Protection

, Component protective facilities required for local protection l

l are shown on Figure 8 and are as fullows :

i I

1. Turbine building (already protected to elevation ,

121'-10" except at door openings whose thresholds are at elevation '119 feet) .

a. Five water-tight doors at door openings will be provided to elevation 122 feet.
b. Water-tight doors will also be provided for the two air shafts located on the west and east sides of the turbine building to elevation 122 feet.

2. Auxiliary building (thresholds of door openings are at elevation 119 feet) .
a. Three water-tight doors at door openings will be i

provided to elevation 122 feet on the east and to elevation 124 feet on the south.  !

3.- Diesel generator building (thresholds of openings are at elevation 119 feet) .

l a. Two concrete barriers will be constructed at the outer side of the air intake enclosure walls to -

elevation 124 feet.

I.

4. Reactor building
a. A concrete water barrier will be constructed up to l elevation 124 feet, approximately three feet outside the present reactor building wall between the equip-ment access hatch and the intermediate building, and between the equipment hatch and the auxiliary building. Each wall will have a water-tight seal at its extremeties.
b. Equipment access hatch will be provided with a

! water-tight door at the entrance to elevation 124 feet.

I

5. Water-tight seals will be installed on:
a. Tendon gallery access hatch t
b. Heat exchanger room hatch
c. At reactor building barrier walls
d. At interfaces between the diesel generator and F

auxiliary buildings.

e. Underground electrical conduit entering the building below grade
6. The v'ent pipes on diesel fuel tanks will be raised to

. prevent the entrance of excessive amounts of water.

7. Water-tight door will be provided at the entrance to the borated water storage tank area to elevation 124 feet.

, (Threshold elevation is at 119 feet) .

6.3 Structural Integrity l All safety-related structures have been checked for both new high

, water criteria (surge levels of 117.4 feet and 121.4 feet) and found to be structurally adequate to sustain the forces, both static and dynamic, caused by the PMH. The intake structure was also found to be structurally adequate to sustain the forces caused by the PMH.

6.4 Rainfall Protection l

1 6.4.1 With the exception of the diesel generator, all other components l are protected from rainfall and water spray created from high winds. l l

6.4.2 In the diesel generator building it is possible for spray to be driven into the air intake opening; however, this contingency has been prepared for by providing suitable floor drainage to intercept

, the water and conduct it away from the area.

6.4.3 Outside the structure, the site drainage system has been designed to preclude ponding, even during the Probable Maximum Precipitation (PMP). The design utilized the Rational Method with the following i

-f

,, parameters:

- Rainfall Intensity - 10 inches per hour Runoff Coefficients: 0.95 for roof surfaces 0.80 for paved areas 0.40 for soil

-r .

i 6.4.4 The greatest overland distance that runoff must travel to reach a catch basin is only 200 feet, at a minimum ground slope of 0.5%.

f 6.4.5 Roof drains discharge directly into the storm drainage system, and were designed to accommodate a rainfall intensity of 6 inches per hour. For this design capac'.ty, no roof ponding will occur up

, to a 1000-year rainfall. In the event of the PMP, ponding could i i

! occur up to a maximum of three inches around the eaves of the structures, and buildup beyond this would overflow the eaves.

The roof structures have been adequately designed to support the f

ponded water.

. 7.0 WATER-TIGHT DOORS

-l-- With the exception of the large turbine room door where the track 6

enters and the two large openings on the south in the fuel handling area, permanent doors will be installed on thi structure ready to be closed in the event of an emergency. These doors will feature i fail-proof, leak-proof, compression-type seals that are activated when the door is closed and latched. The remaining three large openings mentioned above will require mounting of flood panels I

when the need arises. These panels will feature expandable seals that compress against the door casement. In the unlikely event f

of a seal failure, these panels will have a compressi6n-type seal as a backup measure. If the main seal should fail, hydrostatic pressure will force the panel against the back face of its guide j slot compressing the backup seal.

, 8.0 PROTECTIVE EMBANKMENT 8.1 General Description 8.1.1 The plant structure is protected by a surrounding embankment constructed to elevation 118.5, which will be placed upon in-situ material at elevation 98. (See Figure 7) . Because it is vital to the protection of the plant, the embankment along the south r- and west sides of the plant has been designed to withstand the c

I dynamic forces of the maximun met and ensuing runup for the f

Probable Maximum Hurricane. The usual type of protection for this condition would be an adequate thickness of large size e

dumped riprap. Because of the absence of suitable riprap material in the area, soil-cement was originally considered as an effective i

means of preventing erosion of the slopes of the protective

{ embankment. The original selection of soil-cament as the means l

for providing protection for the embankment was predicated on I

( four basic considerations:

1. The absence of rock or other suitable similar material in r

the area.

{ 2. The availability of native limerock with a very high calcium carbonate content, which will permit the soil base to react 5

l chemically in a soil-cement mixture, developing an extremely

coherent internal structure. (The results of tests on this l-limerock material are contained in the Attachments.)

f

3. The results of scil-cement design mixes and tests conducted t

by Pittsburgh Testing Laboratory utilizing local native limerock and cement. (The tests results are contained in three reports included in the Attachments.) '

8.1.2 Due to revised . hurricane criteria and analyses, the surge level has been changed from an original elevation 112.6 to elevation 117.4.

Wave heights have correspondingly increased from an initial height -

of 11.4 feet to 15.0 feet. To provide greater resistance against the increased wave. forces, an armor covering of 3000 psi reinforced

, concrete over 1500 psi soil-cement is planned. The reinforced concrete will provide .c.istance to erosion and dynamic impact

, and the 1500 psi soil-cement will provide a stiff backing and act as a rigid material that the concrete covering will be keyed into.

7he criterion of 1500 psi for the soil-cement is based on a 90-day compressive strength. Thus, referring to Figure 7, it can be seen that the current design employes a layered system of in-situ lime-rock, compacted Zone III fill, soil-cement and reinforced concrete.

8.1.3 Stability analyses were undertaken for the enbankment in order to establish the degree of stability the embankment possesses against a hypothetical failure along a circular are passing through both the foundation and the embankment. Using the following parameters, the minimum factor of safety against failure is 4.3.

8.2 Foundation Material

[' 8.2.1 The foundation material upon which the embankment will be constructed was placed in 1964 from construction excavations on-site. This

(

j material has had nine years to consolidate, with considerable r- construction activity surcharge. No significant settlement is

}

\ anticipated from this material or from the Zone III material placed j'

in the embankment under 95 percent of Maximum Modified Proctor density compaction criteria required by GAI Specification SP-5901.

( -

i Any potential settlement will occur prior to the placement of the concrete cover since the full weight of the embankment will be I*

imposed on the foundation first during construction.

8.2.2 The characteristics of the limerock material existing as foundation j material, and proposed for the embankment, are documented in the FSAR and in the Attachments of this report. The material is a l

f friable limerock with a high magnesium carbonate and calcium carbonate content and the following general characteristics:

, 8.3 Zone III Ffil p 8.3.1 The general characteristics of Zone III fill were mentioned in Subsection 8.2.2. When compacted to 95% of Modified Proctor density, I as required by Specification SP-5901, "one III becomes a very dense

,, and stable material.

8.3.2 The gradation of the material is shown on Figure 9 as a range

(

f covering samples tested during placement in the embankment and in soil-cement design mix tests. It should be noted that in 40 tests of field density, the compaction averaged over 98 percent of maximum Modified Proctor density.

t 8.3.3 The compacted Zone III material has a low permeability of 1 x 10 -5 I

cm/sec and it was noted in conducting triaxial shear tests that I; difficulty was experienced in attempting to saturate the samples.

This characteristic will be beneficial in preventing potential uplift forces from developing beneath the surface materials. ae embankment mass will not respond quickly to saturation from

(

increasing tide levels that have a duration of only 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> since

{ several weeks would be required to totally saturate the mass.

4 I 8.4 Soil-Cement I -

8.4.1 'Ihe design of the soil-cement section was based upon the results f

l of its use and documentation in Bonny and Merritt Dams by the

-- Bureau of Reclamation, and also on the results of three design-mix s

programs conducted by Pittsburgh Testing Laboratory, which are

( included in the Attachments to thf.s report. The use of soil-

'("

cement in these cases was for the actual armor protection, t

) 8.4.2 The results of the three test programs conducted using Crystal River materials are contained in the Attachments. Mixes A and B f

were tested in October of 1969 utilizing Zone III material and 3 Type II cement in proportions of 9 and 10 percent by weight.

Average 28-day compressive strengths for Mixes A and B were f 1140 and 1420 psi, respectively. The second program in November

, 1969 used also Zone III Material and Type II cement in three t

mixes containing 3, 4 and 4.5 bags /cu. yd. These mixes developed i average 90-day compressive strengths of 1850, 2150, and 2960 psi, I

respectively. The third program in July 1970 used Type I cement f in proportions of 7, 8 and 9 percent by weight with Zone III N-material. Average 90-day compressive strengths for Mixes 1, 2

( and 3 were 930,1100 and 1240 psi, respectively. The test results for all three programs are summarized in Tables 4, 5, 6 and 7 and on Figures 10, 11 and 12.

l' 8.4.3 Placement of soil-cement shall be in accordance with GAI

Specification SP-5901 and will yield a 90-day compressive strength of 1500 psi.

i 8.5 Reinforced Concrete Armor 8.5.1 The use of concrete as protection is quite common. Concrete has t

been used to pave dans and levee slopes , used as shore protections f along coast lines, used as dams to contain lakes and reservoirs,

, and used as spillways which are su';jected to a degree of abuse which could never be equaled in its use as the embankment protection at Crystal River 3.

8.5.2 During a PMH, the concrete armor would be subjected to a maximum I

dynamic load of 32 psi. Although the probability of a washout f ever occurring beneath the armor is nearly zero, for design pur-posed it was assumed that the individual concrete panels, whose f maximum size will be 20 feet square, had a washout occur beneath them. It was also assumed that the washout lef t a 15-foot square area unsupported, thus introducing bending stresses. Based on

} working stress design, the concrete reinforcement was designed to resist the bending stresses in this unsupported condition. Both the concrete and reinforcing stresses are within thu allowable

tolerences provided by ACI-318-63, based on working stress design.

,. 8.5.3 Since the chances of a washout are unlikely, the armor will

\

i always be continuously supported. The only induced stresses, therefore, will be purely compressional. This , then, indicates that the armor is very conservatively designed.

f 27 9.0 PROTECTION AGAINST A SURGE LEVEL OF 33.4 FEET 9.1 Desian Conditions If it is required to use the 33.4 foot surge level, the stillwater level hydrograph, generated wave height, breaking wave height and wave runup would be approximately as shown on Figure 15. As can

! be seen from Figure 15, the intersection of the breaking wave curve and the~ generated wave height curves shows that with the highest 1 percent of the waves breaking, the maximum height of a the waves that can travel across the fill approaching the plant "

, is 18.0 feet. With the average of the highest 33 percent (shown

\.

as Hs) of the waves breaking, the maximum height of the waves that can reach the protective embankment without breaking is 15.5 feet.

9.2 Alterations to Plant Protection l

If one must consider protection against a surge level of 121.4 feet, f the following changes would need to be made to the existing

, protection scheme: l

),

q 1. The embankment on the south and west sides would be increased I l

in height to elevation 127 feet (Refer to Figure 14). This would be necessary in order to intercept waves and floating )

{ debris such as an oil barge before the structure is struck.

s

2. Barriers and water-tight doors with a top elevation of 124 f feet would increase in height to elevation 127 feet.
3. Water-tight doors with a top elevation of 122 feet would increase in height to elevation 127 feet except openings on I - - -

the east side of structure which would increase to elevation L.

124 feet.

< 4. A concrete barrier with a top elevation of 127 feet must be

~

( - built at _ a distance of about 2 feet outside the present turbine room wall (See Figure 13). This barrier would extend from the main transformers toward the west and around to the air shaf t located on the west side of the turbine room.

(

[ 5. Prior to high water, the neutralizar tank, condensate storage 4* tank and fire water storage tanks must be filled for stability.

9.3 Likelihood of Surge to Elevation 121.4 9.3.1 The unlikelyhood of the surge reaching a level of 121.4 feet is

( is verified in the Dames and Moore Report dated July 13, 1973.

Because of this confidence, Shetion 9.0 of this report has been i included only to answer question 5(d) of Enclosure 1 of the AEC

, letter to Florida Power Corporation dated March 12, 1973.

,I 9.3.2 It is concluded that the protection described above for a surge level of 121.4 feet represents the same assurance of safe pro-tection as described for the 117.4 foot surge level. However, it is further concluded that a lesser but. safe level of protection j could be accomplished, based on AEC requirements , by elimination of protection item 1 above and increasing the height of water-(

tight doors and concrete barriers to elevation 129 feet, thus i

< liminating a significant cost penalty in protection schemes i

5-between surge levels of 117.4 and 121.4 feet.

PROFILE 1 - SMOOTH SLOPES WITH MAXIMUM BERM ELEVATION 118.5 FT.:

i NO OVERTOPPING OCCURRED FOR TIDE LEVELS RANGING FROM 104 TO 110 FT.

OCCASIONAL OVERTOPPING STARTED WHEN THE TIDE LEVEL WAS 112 FT., BECOMING CONTINUOUS FOR TIDE LEVELS FROM 114 TO 118 FT. MAXIMUM OVERTOPPING DEPTH DEPTH NOTED WAS 88 INCHES.

PROFILE 2 - SMOOTH SLOPES WITH MAXIMUM BERM ELEYATION 124.0 FT.:

{ NO OVERTOPPING OCCURRED FOR TIDE LEVELS UP TO 112 FT. SLIGHT OVERTOPPING WAS RECORDED WITH A 114 FT. TIDE LEVEL. CONTINUOUS OVERTOPPING OCCURRED I

~

I FOR TfDES OF 116 TO 120 FT., WITH A MAXIMUM DEPTH OF 40 INCHES.

[ PROFILE 3 - STEPPED SLOPES WITH MAXIMUM BERM ELEVATION 118.5 FT.:

NO OVERTOPPING OCCURRED FOR TIDE LEVELS FROM 104 TO 112 FT. SLIGHT OVER-TOPPING HAPPENED WITH A TIDE LEVEL OF 114 FT., BECOMING CONTINUOUS AT TIDES OF 116 AND 118 FT. MAXIMUM OVERTOPPING DEPTH RECORDED WAS 66 INCHES.

PROFILE 4 - STEPPED SLOPES WITH MAXIMUM BERM ELEVATION 124.0 FT.:

SLIGHT OVERTOPPING BEGAN WHEN THE TIDE LEVEL WAS 118 FT. AT A 120 FT. TIDE, THE MAXIMUM OVERTOPPING DEPTH WAS 40 INCHES. IN ORDER TO ELIMINATE ALL OVERTOPPING (NEGLECTING SPLASH-UP), IT WAS NECESSARY TO INCREASE THE 124 FT.

ELEVATION WITH STEPS UP TO AN ELEVATION OF 132.4 FT.

PROFILE S - STEPPED SLOPES, SLIGHTLY DIFFERENT DESIGH THAN PREVIOUSLY

( TESTED (LABELED LAYOUT NO. 3, SECTION B BY gal):

, STEPS WERE CONTINUED ABOVE THE BASE ELEVATION OF 118.5 FT. IN ORDER TO

PREVENT OVERTOPPING FOR THIS SERIES OF TESTS. MAXIMUM RUNUP PEAKS WERE SLIGHTLY LESS FOR THIS PROFILE THAN FOR OTHERS TESTED.

CLIENTS No. P.O. No. PR3-1106 REPORT ORDER No. TA-7732 REPORT FOR: FLORIDA POWER CORPORATION P.O. Box 276 Crystal River, Florida 32629 i REPORT OF: Soil Cement Design Mix.

        ,                                        DATE:                                 7-29-70
         ,                                At the request of Florida Power Corporation, a series of tests were performed to develop a soil-cement design acceptable for the wave protection berm on Crystal River Unit #3.

The PSAR section on soil-cement berm construction references the Bonny Dam project of the US Bureau of Reclamation on which a test section of soil-cement was constructed for wave erosion protection in 1951. (Report EM-630) Thuefore it was felt that research into the design and testing methods used by BUREC on that project should provide guidance for the berm construction

        ,                                 on Unit #3.
       ;                                  An in-depth look at the BUREC reports on the Bonny Dam and a j                                  subsequent project, the Merritt Dam, revealed a basically differ-ent approach from that detailed in the PSAR. The PSAR establishes compressive stren8th of the soil cement mixture as the basic de-sign criteria while BUREC on the above projects follows basically L-                                  the Portland Cement Association recommendations for design of soil-cement mixtures subject to erosive action. This involves a series of wetting and drying and/or freezing and thawing tests to
 ' ^ ~                   ~

establish minimum acceptable cement content. The Merritt Dam report, written 16 196'1," stat s', " Compressive ' strength ~ is. generally ~ - ~ considered supplementary to the freeze-thaw and wet-dry soil-cement tests." (EM 611, p.7) one very basic difference between the Bonny Dam project and Crystal River Unit #3 is the nature of the soil from which the soil cement will be manufactured. On the Bonny Dam job , soil used was quartz sand with 207.-357. sile. This basically forms a matrix type structure with the cement and develops its coherence through an internal physical type bond between the individual soil particles and the hydrated cement gel. Conversely, the

                           ~

material to be used on this project as a soil base is native excavated,vell weathered limestone with a'very high calcium carbonate content. This composition permits the, soil base it- ! self to react chemically in the soil-cement mixture, forming Page 1.

Sano OVE REPORTS 19 RESERVED PENGING OUR WWiffEN a PPROv a"k."" REPORT cement-like bonds between individual particles and, along with the cement gel, developing an extremely coherent internal struct-ure. Results of the wetting and drying tescs which were performed verify this point quite graphically. One further point concerning the compressive strength criteria of the PSAR section should be made. Reference is made in that section to the 2,000 PSI strength of cores taken from the Bonny Dam test section. It should be clearly understood that these cores were taken some 10 years af ter construction of the test section and - that normal PCA procedures require only that compressive strength of a soil-cement mix be at least 450 PSI and increasing at age 7 days. 28 day strength at Bonny Dam were in the range of 900-1100 PSI, which is roughly comparable to 28 day strengths obtained here at Crystal River. In consideration of the above, it was decided that the PCA recom-mendations for soil-cement wave protection design would produce an acceptable structure with a more economical mix than the orig-inal PSAR recommendations. 1 Portland Cement Associacion design criteria as followed by BUREC l on the Bonny Dam project are as follows:

1. Soil-cement losses during either 12 cycles of vet-dry or of freeze-thaw tests shall not exceed 14 percent.
2. The maximum volume change during either the wet-dry or f freeze-thaw tests shall not exceed 2 percent of the volume at the time of molding.
3. The maximum moisture content during the wet-dry or freeze-thaw test shall not exceed that quantity which will completely fill the voids of the specimen at the time of molding.

REPORT Soil samples were taken from excavated native limerock material stockpiled at the site. No attempt was made to selectively grade the samples, other than to screen all material over a 3/4" sieve ' for purposes of laboratory testing. (- Cement contents of 77., 87., and 97. by weight were used in prepar-ation of the test specimens. These mixes were designated respect-ively for test purposes as Mix #1 containing 219 lbs. of cement

         ,                                       per. cu. yd. of soil-cement mixture, Mixf2 containing 251 lbs.

per.cu. yd., and Mixf3 containing 282 lbs. per cu. yd. . Maximum density and optimum moisture of soil-cement mixtures i were determined in accordance with ASTM D558, except compactive l effort was modified to 5 layers, 25 blows with 19 lb. ranuner falling 18". 5'.5 Test specimens were prepared at moisture contents slightly above optimum and compacted in 4" diameter molds in the above described

       ,                                         manner. These samples were then removed from the mold and cured for 7 days in a temperature and humidity controlled curing room, after which they were used for wetting and drying and compressive strength tests.

Results of the wetting and drying tests show extremely low weight losses for all specimens, indicating a very coherent and durable structure. Compressive strengths at 90 days were in the range of 1000 PSI or higher and steadily increasing. Several specimens of Mix #3 were were arbitrarily tested for splitting tensile strength 7 , in accordance with ASTM C-496 and developed a range of 200 PSI, which is higher than concrete of comparable quality.

Dear Mr. Harris:

Enclosed you will find data on laboratory compaction and field density testing of the limerock fill compacted as Zone III material. Figure I summarizes compaction to date. The figure #2 entitled Compaction Characteristics was made up for J. A. Jones Company at the request of Gus Packos when the compaction difficulties arose with the only available limerock material. After consideration of the data on this figure, we ad-vised J. A.' Jones to use a tamping foot roller for initial com- k paction followed by the 30 ton rubber tyne roller. The field

                                                                                                                                                                                  )

results have borne out the conclusions drawn from the laboratory 1 i testing; in other words, that high stress kneeding type compaction would be required to achieve the required density. All of the field data indicates that the compaction water contents are well j wet of optimum for the high energy comgaction now being used, but drying the material has not be practical.

Mr. James Harris November 22, 1972 Page 2                                                            TA-7732 The laboratory study indicates that the controlling perameter in the moisture-density relationship for any limerock sample appears to be the specific gravity of particles. This factor seems to be a highly variable quantity and determines the maximum density to which
  .               that sample can be compacted.        We also found that the specific gravity of the particles scalped according to ASTM D-1557, Method c, was higher than the specific gravity of particles for the remaining material. The reduced field average specific gravity leads to the need for increased compaction effort in order to reach the requirements established in terms of Method C.

The results of triaxial testing are being sent under seperate cover. We apologize for the delay, but the requirement for the measure-ment of pore pressures in compacted samples made our own equipment inadequate for accurate testing. Due to the necessity for high back pressures in order to prevent pore water cavitation due to dialation,

 -                none of our usual sources were adequate either.         Since we were in the process of up-grading our own equipment, we decided to rush the re-building rather than try to squeeze in on someone else's time schedule for tests in which little faith could be put in the results.             The test series is now complete and will follow this data immediately.

We appreciate the opportunity of handling this testing for you and shall be glad to discuss the results witih you at any time. Respectfully submitted, PITTSBURGH TESTING LABORATORY c-1 -

December 7, 1972 PTL Ref: TA-7732 Mr. James Harris Gilbert Associates 525 Lancaster Avenue Reading, Pennsylvania 19602 Re: Triaxial Testing Florida Power Corporation

Dear Mr. Harris:

Enclosed please find the results of triaxial testing con-ducted by us on Zone III compacted limerock. fill. The triaxial sample size was 1.40" p x 2.985". Due to the small sample size, the air dried limerock was scalped on a #8 sieve and compacted by a 1/2" Gf kneading tamper in 5 layers. We believe that this will result in, a conservative estimate of insitu strength since greater particle interlocking c.ould be expected insitu. Both drained and undrained tests with pore pressure measure-ments were run to assure the determination of the proper effective stress failure envelope. Difficulties were experienced with the undrained tests due to the extreme sample rigidity and negative pore pressure change generated by the shear stress. The tests were run in a Wykeham-Parrance triaxial cell with a dead load lever apparatus used to apply the deviator stress. Pressure measurements were made using a Tyco 200 PSI piezoelectric j pressure transducer. PIT T bTWSGet htw venet .0S704 PMtL ADELPoe6A CLtvtLAND DETRolf S t.

Mr. James Harris December 7, 1972 Page 2 TA-7732 The cell pressure and back pressure were applied through air-water interchange system with the pressure control supplied by Bellofram having a sensitivity of one part in 5000 air regu-lators. The minimum back pressure was 40 PSI. Data reduction was done by programs written by PTL for , the Wang 600 programmable calculator. Figure 1 shows the triaxial test densities and their re-lationship to field density and compaction characteristics of the Zone III limerock. Figure 2 is the stress path results from the drained triaxial tests and Figure 3 the stress path results of undrained triaxial testing. Figures 4 and 5 are the stress-strain data.
