Functional or Program Areas Inspected 1.

Background and Purpose of the LACBWR Subsurface Study As part of the Systematic Evaluation Program (SEP), the NRC staff indicated that the seismic evaluation of the La Crosse Boiling Water Reactor performed by Dairyland Power Cooperative did r.ot include sufficient data concerning seismic design input and structural capability for safety related structures, systems and equipment to withstand earthquake effects.

(ref: NRC letter to DPC dated Janua ry 15, 1979) An analysis was performed by the U.S. Army Engineer Waterways Experiment Station (WES), Vicksburg, Mississippi. The results of their analysis are contained in a report entitled, " Liquefaction Analysis for La Crosse Nuclear Power Station", dated December 1978.

On January 9,1979, a meeting was held to discuss the liquefaction potential at the LAChi9 site and the results of the WES analysis (ref: NRC memo dated Jaciary 20, 1979). At this meeting it was agreed that it would be appropiate to initiate a soils properties investigation program. This program was to include obtaining undis-turbed soil samples at the site and conduct laboratory cyclic triaxial tests to better define the soils properties.

-2- \\'\\ .

.

A subsequent meeting was held on February 9, 1979, to discuss the current available information on liquefaction potential at LACBWR and the soils properties investigation program for resolving this issue under the NRC Systematic Evaluation Program. The proposed soil properites investigat-ion program described by Dames and Moore included taking at least four borings at strategic locations on the LACBWR site as well as laboratory testing of the samples from various depths of interest.

(ref: NRC memo dated February 15, 1979.)

Dames and Moore then.ubmitted a report entitled, " Review of Liquefaction Potential LACBWR" for DPC of which Section 7.0. describes the recomendations for further site investigation work. 'This report was reviewed by the WES and coment submitted to the NRC.

(ref: WES letter to NRC dated April 4, 1979.) One of the coments made was the tests may be critical to the evaluation of liquefaction at La Crosse and should be closely monitored by the NRC staff.

As a result of this recomendation, RIII office was requested to have an inspector observe site sampling of the subsurface materials and laboratory tests. The following sections describe the observations and records review by the RIII inspector.

R2 view of Procedures for Site Soils Investigation Dames and Moore and Raymond International used the following quality assurance procedures for the site test borings and associated work: QA Procedure No. S'., dated May 18, 1979.

(Attachment 2) a.

b.

Specification for Test Borings.

(Attachment 3) These procedures are attached for the information of NRC Geosciences Branch (NRR).

The program required four test borings identified as DM-7, DM-8, DM-9 and DM-10.

Two borings (DM-8 and 10) were to provide continious blow count values using standard penetration test for the collection of "N" values continuously at various depths. Two other borings (DM-7 and 9) were to provide " undisturbed" samples for insitu density tests and cyclic triaxial laboratory tests. The " undisturbed" samples were to be recovered according to report entilted " State-of-the-Art of Undisturbed Sampling of Cohesionless Soils" by W. Marcuson and A. Franklin to be presented at the International Symposism on Soil Sampling in July 1979.

In addition, test borings were to be performed in accos. dance with ASTM D-1586, " Penetration Test and Split-Barrel Sampling of Soils" and ASTM D-1587, " Thin-Walled Tube Sampling of Soils."

The detailed sampling procedure for recovering and handling " undisturbed" samples is contained in Dames and Moore procedure No. 53, Section 2.1.1 (sampling procedure).

Observation of Test Borings at LACBWR Site A number of photographs were taken of the site soils investigation and are included in Attachment 1 of this report.

The following specific observations were made during the standard penetration test borings and undisturbed Osterberg sampling performed by Dames and Moore: __ a.

Standard Penetration Test Boring (DM-8) The following equipment was used for the test boring: (1) Mobile B-61 drill rig (2) Type "A" drill rod; 10 ft lengths (3) Two raps of rope around cat head; rope lubricated periodically (4) Tri-cone diffused discharge type drill bit (4 1/8" diameter) (5) 140 lb. hammer; 30-inch drop (6) 7.56 lb. anvil (7) Standard split spoon sampler The test boing was performed in accordance with ASTM D-1586.

Penetration (blow /ft) and soil classification were recorded on boring logs. Split spoon samples were recovered and job samples retained for lab classification.

Boring holes were filled with cement material by dropping material into borehole and rodding.

b.

Undisturbed Sampling (Boring DM-7) It was understood that one of the objects of the site testing was to recover relatively " undisturbed" soil samples at various depths which were to be used for laboratory cyclic triaxial tests in order to determine soil properites and the effect of a seismic event on soil liquefaction. The sampling method which was to be employed is contained in report entitled " State-of-the-Art of Undisturbed Sampling of Cohesionless Soils" by W. Marcuson and A. Franklin.

Undisturbed sampling (Boring DM-7) was performed by Raymond International Drillers under the technical supervison of Dames and Moore field engineers and Dr. M. Silver of the University of Illinois, Chicago Circle Campus.

The following specific observations were made during the test Boring DM-7: (1) " hen drilling was below the water table drilling mud (Quik-Gel Bentonite) was used to support the wall of the hole.

(2) A modified fish tail bit with baffles installed to deflect drilling fluid upward was not used as recommended.

Instead a 4 1/8" diameter tri-cone difused discharge bit was used.

(3) The " push" on the Osterberg piston was uninterupted; the thin-walled tube sampler was 3 inches in diameter.

1' -5- \\

(4) The hydraulic fluid pressure for the drive mechanisr was not determined since a gauge was not available on the drill rig.

(5) The withdrawal of the sampler tube was in a manner to minimize sample disturbance.

(6) The thin-walled tube was cut from the Osterberg piston using a pipe cutter to relieve the vacuum after withdrawal from the borehole.

(7) Samples in the thin-walled tube were plugged on lioth ends with an expandable "O" ring which included a means of allowing drainage of the sample. Drainage was required for a minimum of 24 hours prior to freezing.

(8) The samples were planned to be frozen onsite using dry ice and the transporting the samples to a local freezer plant.

The samples are then planned to be transported to the University of Illinois laboratory in Chicago, by Dr. M. Silver, for preparation and testing. The inspector observed the samples being handled carefully to minimize disturbance.

  • 1.0 INTRODUCTION 1.1 General

. In 1973. Dames & m ore (D&M) performed a Geotechnical Investigation of Geology, Seismology, and Liquefaction Potential at the La Crosse Boiling Water Reactl>r (IACBWR) site. The contents of the 1973 Dames & Moore report were sui:ctitted to the U.S. Nuclear Regulatory Commission (NRC) in 1974, as _ a part of the application for an operating license for the IACBWR plant.

In its 1973 study, Dames's more concluded that the IACBWR plant had adequate factors of safety against potential for liquefaction under the design Safe Shutdown Earthquake (SSE).

In 1978, NRC initiated a review process under its Systematic Evaluation Program (SEP). As a part of SEP, the U.S. Army Engineer Water-ways Experiment Station (WES) was requested by NRC to review the 1973 Dames & more soils investigation.

WES, after reviewing the data and analysis presented by Dames & Moore, performed its own analyses based on rather con-servative iriterpretations of the sare data. The WES report, submitted to NRC, and made public in 1978, concluded that the factors of safety against liquefaction were considerably lower than those calculated by Dames & more in 1973.

Upon request by Dairyland Power Cooperative (DPC), Dames & Moore re-evaluated its 1973 analyses and reviewed the 1978 WES analyses. Based on this effort, Dames & Hoore presented to NRC a position which was essentially consistent with its 1973 study.

However, there are certain questions that have been raised by NRC regarding the lack of test data on undisturbed samples and lack of continuous standard penetration test results. Since the ehisting data do not satisfy these new. concerns, Dairyland Power Cooperative has decided to perform st field and laboratory investigations and limited analyses to verify the earlier finding: on liquefaction potential.

Attachment 2 Page 2 of 16 g \\' . < .

. 2.0 '1HE PROGRAM The new program planned for the 1.ACBWR site consists of: (a) a .

n.

  • test boring program consisting of a minimum of 4 borings, (b) a limited laboratory program, and (c) a limited amount of analyses.

. 2.1 Test Boring Program . Twelve test borings were drilled during previous investigations before 1973. Six additional test borings were drilled in 1973 under Dames & teore supervision. The purpose of drilling the proposed four additional borings is to verify the findings from the 1973 investigation. The approxi-mate locations of the four proposed borings, DM-7, DM-8, DM-9, and DM-10, are shown on Figure 1 along with the borings drilled jreviously.

It is proposed that these holes be drilled to a minimum depth of 100 feet.

The final location of borings will be determined at the site after the DPC exact representatives approve of the recommended locations.

(DPC will check to make sure that no underground pipelines, cables, etc., will be encountered at the boring locations). Borings DM-7 and DM-8 will be drilled as close as possible to DM-1, and DM-9 and DM-10 will be drilled close to DM-3.

DM-7 and DM-9 will be used for continuous sampling while DM-8 and DM-10 will be drilled for per-forming continuous standard penetration tests (ASTM-D1586-70). The purposes of the above arrangement are that: (a) DM-8 and DM-10 will provide continuous blow count values using standard split spoon.

(n e previous use of other samplers, such as Osterberg and Dames & Moore Type U, had precluded the collection of "N" values continuously at all depths drilled). (b) DM-7 and DM-9 will provide the best possiale ("relatively undisturbed") samples for in situ ~ density determinations and cyclic triaxial tests.

Therewillbeabasisforestimatinginsitubensities (() and relative densities by correlation with blow counts and for comparing the new data and the data already collected.

(he proximity of the new test boring locations to the previously drilled test borings should facilitate such a comparison).

Attachment 2 ,,, Page 3 of 16 \\\\, .C

. < . .

. . . General outlines of procedures developed recently (Ref-1) will be followed for " undisturbed" sampling of sand under the water table. Three- ..,. inch diameter thin wall tube sar;plers will be used if the tube can be pushed into the soil (ASTM-D-1587-67). If the above procedure fails, other samplers such as Pitcher and Osterberg piston samplers will be used to obtain samples.

Drilling mud will be used while drilling to keep the hole from caving in and also to help retain the sample in the sampling tube. h e drilling operation will be performed by a qualified drilling contractor under the i supervision of a Dames t. Pbore field engineer.

It is proposed _ that some moisture and density tests be performed at the site on a few samples immediately aftar extracting them, to minimize the possible effects of sample disturbance during transportation.

The " undisturbed" samples obtained from the test borings DM-7 and DM-9 will be transported carefully (in specially prepared boxes packed with cushions) to the laboratory for testing. The split spoon sa=ples from borings DM-8 and DM-10 will be used for visual classification and logging in the field and further laboratory classifications.

2.1.1 Sampling Procedure 1.

Sampling shall be performed in a mud filled hole with a diameter only slightly larger than the diameter of the sampler to be used.

2.

A fish tailed bit modified with baffles that directs the drilling fluid upward away from the bottom of the bore hole shall be used to advance the hole.

3.

Casing in the ' top of the boring and a mud level above the ground water table shall be used to prevent caving of the hole.

4.

While the sampler is being withdrawn from the bore hole, fresh drilling mud shall be introduced into the bore hole to prevent caving.

5.

When the sampling tube just clears the bore hole, a '. small amount of soil shall be removed from the core tube and an expandable 0-ring packer shall be intro- , duced into the tube and locked to prevent the loss.of sand. The packer shall have holes to facilitate d'ainage.

r 6.

A small drill shall be used to make a small hole in the top of the tube to break any vacuum developed in top of the specimen.

7.

h e dimensions and weight of the sample shall be obtained.

9.

Samples shall be quickly frozen in dry. ice or in liquid nitrogen.

. 10.

Samples shall, be stored in a freezer or comerhia'l' freezing plant if they are not to be immediately transported to the testing laboratory.

11.

Soples shall be transported in the frozen state using either dry ice or other refrigeration technique 2.2 1.aboratory Program . A minimum of six stress-controlled cyclic triarial tests on " undisturbed" samples and/or on reconstituted samples shall bayerformed.

Samples shall be selected from critical depths and. shall be consolidated under pressures corresponding to the in situ effective confining pressure.

The stress ratios at failure will be selected to obtain a good definition of stress ratios versus ntanber of cycles required to cause liquefaction.

Several moisture and density tests, several grain size distri-bution tests, and a few specific gravity tests are also proposed.

If the in situ densities measured under the proposed program show significant differences when coz:: pared to those measured under the previous investigation, a limited nu=ber of strain controlled cyclic triaxial tests will also be performed on " undisturbed" and/or remolded samples to define the variation of shear moduli and damping ratios with strain levels.

Standard procedures recomended by ASTM will be followed for all static tests mentioned above. The Dames & Moore Manual of Technical Practices procedures will be followed for any nonstandard tests.

2.3 Analyses The following analyses shall be performed to estimate the factors of safety against liquefaction for the IACBWR site.

(a) Seed & Idriss simplified analysis (Ref. 2) (b) . empirical analysis using data on past performance of Various sites under different earthq,uakes (Ref. 3) I { (c) modified Japanese analysis (Ref. 4) (d) one-dimensional wave propagation analysis using the computer program SHAKE (Ref. 5) After analyzing the results of the above analyses, a final con- ,o clusion regarding the fae*.or of safety against liquefaction will be ' made, p OM ,,y ba Attachment 2 Page 5 of 16 o , -, , .

. of the Engineer. h e Contractor shall coordinate the drilling work with the Engineer in the field to permit sufficient time for the Engineer to evaluate ' the subsurface conditions encountered and select the approp'rlate, depth for +w.. . subsequent samples or for terminating each boring.

If a sample is not recovered from a boring at a particular depth, or when, in the opinion of the Engineer, the sample recovered is disturbed or not representative of the subsurface materials at the same depth, the Contractor shall, if requested by the Engineer, thoroughly clean the boring to the bottom of the previous sample to the satisfaction of the Engineer and extract a representative sample at the required depth.

-- De sampling techniques shall be subject to the approval of the Engineer. Where loss of samples is judged by the Engineer to be the result of the techniques and/or equipment employed by the Contractor, the Contractor may be required to change his equipment.and/or techniques in order to obtain " undisturbed", representative samples. In the event that the Contractor fails to improve upon his technique or his equipment, the Engineer is authorized to suspend the work until the requested modifications are employed to the sat.isfaction of the Engineer. No payments shall be made for work performed after the Engineer has requested that the work be suspended, and no payments for stand-by time will be made for the period in which the drilling activities e would be suspended, ne person authorized to request suspension of the work will be the Dames s Moore Project Manager.

Should the casing or apparatus be removed from a boring without the permission of the Engineer, or should a boring be started and for any reason not extended to a depth required by the Engineer, or should the Contractor fail to extract representative samples consistent with the specifications, thereby rendering the data of questionable validity and value because of lack . ~ of continuity, then the Contractor shall perform an additional boring at a location selected by the Engineer; no payment shall be made for the abandoned boring; however, payment for satisfactory samples obtained therein may be made at; the discretion of the Engineer.

. 2.6 Backfilling Borings Upon completion of all work in each boring, the Digineer will direct the Contractor either to backfill or to seal the holes by suitable grouting operation. Natural materials extracted from the borehole during drilling shall Attachment 3 ' > -{' .y l y - Page 7 of 12 . [i h'~/2ljh:l3I b d L.
