INTERVENOR STAMIRIS' CONTENTION NUMBER 3

-Q.1. Please state your-name and position with the NRC.

A. My name is Eugene J. Gallagher. I am a civil engineer with I the U.S. Nuclear Regulatory Commission.- Since February,1981, I have

.been assigned.to the Reactor Engineering Branch, Division of Resident and Regional Reactor Inspection, Office of Inspection and Enforcement. Prior

,} to February,1981, I was a reactor inspector assigned. to the Region. III, Reactor Construction and Engineering Support Branch, Office of Inspection ,

and Enforcement.- I was assigned to the Midland Plant (among others) from October,1978' until January,1981. . , [

Since October of 1978, I have spent approximately one year of effort l performing inspections, reviewing quality control records and procedures, observing work activities, reviewing Consumers Power Company (hereafter Consumers) . responses to 50.54(f) questions 1 and 23, attending meetings I and presentations by Consumers and Bechtel regarding the soil settlement matter at the Midland Plant.

Q.3. Please stateithe. nature of the responsibilities that you had with. respect.to the Midland Plant, Units 1 and 2.'

. A. As a civil engineer. inspector for the Region III Office of Inspection 'and Enforcement I conducted five inspections prior to December 6,1979 in order to (1) ascertain whether adequate quality assurance plans, instructions and procedures had been established for the l construction of the foundation of safety related structures, (2) provide an independent evaluation of the performance, work in progress and

~

completed work to ascertain whether activities relative to foundation

. construction were accomplished in accordance with NRC requirements, and 1

.(3) review the quality related records to ascertain whether. these records reflected work accomplished consistent with NRC requirements and license L O l commitments. -

L Q.4. What is the NRC Staff response to Intervenor Stamiris Contention 3?

A. Intervenor Stamiris Contention 3 reads as follows:

Consumers Power Company has not implemented its Quality

! Assurance Program regarding soil settlement issues according to 10 CFR Part 50, Appendix B regulations, and this represents a repeated pattern of quality-assurance deficiency reflecting a managerial attitude inconsistent with implementation of Quality Assurance Regulations with respect to soil settlement problems, since reasonable assurance was given in past cases (ALAB-100, ALAB-106 and LBP-74-71) that proper quality assurance would ensue and it has not.

The Quality Assurance deficiencies regarding soil settlement include:

L a) 10 CFR Part 50, Appendix B, Criteria III, V, X and XVI l O as set forth in the Order'of Modification; L

a J

- 3-V b) 10 CFR Part 50, Appendix B, additional criteria denoted by roman numerals below:

1. The Applicant has failed to assume responsibility for execution of the QA program through its failure to verify and review FSAR statements (pp. 6-8 and p. 21 Keppler Report) and through its reliance on final test results not in accordance with specified requirements (p.

16,KepplerReport);

II. The QA program was not carried out according to written policies, procedures and instructions, in that oral directions were relied upon and repeated deviations from policies occurred regarding compaction procedures (p.

9-14, Keppler Report);

VII. Control of purchases material has not been maintained, in that examination and testing of backfill materials did not occur in accordance with regulations (NCR QF29, NCR QF147);

IX. Control of non-destructive testing was not accomplished by qualified personnel using qualified l

p)

V procedures regarding a) moisture control (Keppler Report p.14-16; QA l

Request 5040, NCRQFSS2, 172, 174 and 199);

b) compaction procedures (Keppler Report, p. 9, NCR QFS 68, 120 and 130); and c) plant fi 1 work (pp. 24 and 25, Keppler Report);

, XI. Test programs did not incorporate requirements and i acceptance limits adequately in the areas referenced in a, I b and c above, and do not meet these requirements L regarding soil settlement remedial actiors; l

XIII. Measures were not adequately established to prevent damage or deterioration of material regarding frost effects on compacted fill (pp. 16 and 17, Keppler Report);

l XV. Measures were not taken to control non-conforming l

material in order to prevent the inadvertent use (NCR QF29 and QF127);

c) the settlement of the Administration Building in 1977 should have served as a quality indicator, preventir,g the same

I of the diesel generator building causing its eventual settlement.

Before responding to the main allegation of Intervenor Stamiris Contention 3 I will' address,the specific deficiencies she lists in support of the contention.

The Staff agrees with the allegation in paragraph 3(a) which merely relies on facts alleged originally by the Staff in Appendix A to the December 6,1979 Order and in Investigation Report 78-20 (attachment 2).

.With regard to Contention 3(b), the fac'.s set forth describe violations of Criteria III, V, X and XVI as set forth in Appendix = A to the Order. However, Ms. Stamiris using these same facts, has designated violations of other criteria. The Staff does not agree with these designations; supplied by Ms. Stamiris in her contention 3(b). The

(\

Staff's view is that: i tem 3(b) I and 3(b) XIII are examples of violations of criterion III; items 3(b) II and 3('o) IX (c) are examples of violations of criterion V; items 3(b) VII and 3(b) IX (a) and (b) and 3(b) XV are examples of violations of criterion XVI; and item 3(b) XI is an example of violations of criterion V and XVI.

l j As discussed on pages 21 through 23 of the attached NRC

-Investigation Report (attachment 2) the Staff agrees with the allegations inContention3(c).

Ms. Stamiris also references additional Q.A. deficiencies reported I in NRC I&E reports 80-32 and 81-01 and SALP assessment of 11-24-80, CPCo Report 18.4.3.6 and NCR 3401 without any other specification. I authorized I

I received a Bachelor of Engineering Degree in Civil Engineering from Villanova University in 1973 and a Master of Science Degree in Civil / Structural Engineering from Polytechnical Institute of New York in 1974. I am a registered Professional Engineer in the States of

-Illinois (#37828)~, Florida (#29114) and Louisiana (#16376). I am a member of the American Society of Civil Engineers, American Concrete Institute and Tau Beta Pi National Engineering Honor Society.

In my present work at the NRC, I provide technical assistance in the area of civil engineering to Regional offices and resident inspectors with particular enphasis on the design and construction of reinforced and Q prestressed concrete structures, foundations, structural steel buildings and in structural testing and surveillance. In addition, I provide iL 'j technical input for the development' and interpretation of industry codes, standards and regulatory requirements relating to inspection activities.

From 1978 to 1981 I was a member of the NRC Region 3 inspection staff responsible for' the inspections of civil engineering aspects of plants under construction and in operation. This included the Inspection of laboratory and field testing'of concrete, steel and soils materials, earth embankments and dams, material sources, piping systems and reinforced and prestressed concrete structures. In addition, a review of management controls and quality assurance programs were performed at plants under construction. I participated in approximately 90 inspections of reactor facilities.

Prior to joining the NRC Staff I was employed by E8ASCO Services, Inc. in New York City from 1973 to 1978. I performed designs of reinforced concrete and steel structures, design of hydraulic and water supply t

systems and preparation of specifications for construction. From 1975 to j 1978, I was the civil resident engineer at the Waterford 3 Nuclear Plant site responsible for providing technical assistance to construction, t

! Ouring 1972 and 1973 I was employed by Valley Forge Laboratory in Devon, PA performing inspection and testing on concrete, steal and soil materials.

REASON FOR INVESTIGATION On September 7, 1978, the licensee notified Ragion III, by telephone, that the set:1ement of the Diesel Generator Building and foundations experienced consti:uted a matter repor:able under the requirements of 10 CFR 50.55(e). Wri: ten interim reports were subsecuently submitted by the licensee by letters dated September 29 and November 7,1978.

An investigation was initiated to obtain information concerning the circumstances of this occurrence to determine whether: a breakdown in the Ouality Assurance program had occurred; the occurrence had been procerly reported; and, whe:her the FSAR s:atements were consistent with the design and construction of the plant.

SCOPE This investigation was performed to obtain information relating to design and construction activi:1es affecting the Diesel Generator Building foundations and the ac:ivities involved in the identifica-tion and reporting of unusual settlement of the building. The investigation consisted of an examination of pertinent records and

/'~'s procedures and interviews with personnel at the Midland site, the Consumers Power Company of fices in Jackson, Michigan, and the Sechtel

(

\- Power Corporation of fices in Ann Arbor, >dchigan.

SUMMARY

OF FACTS By letter dated September 29, 1975, the licensee submitted a report as required by 10 CFR 50.55(e) cencerning an unural degree of settle-ment of the Diesel Generator Su11 ding (DGB). This reper: confirmed la informa: ion'previded during earlier :elephone conversa: fens on or i

about August 22, 1979, with the NRC Resident Inspec:or and on Sep: ember 7, 1978, with the Region III office. This report was an interim repor: and was followed by periodic interim repor:s providing additional information concerning actions being taken to resolve the problem. Fur:her testing l and moni:ering programs and an evaluation of the resulting da a have l

l been under:aken by the licensee to determine the :ause of the settlemen:

and the adequacy of :he :orrective action being takan. The results of

hese efforts will be submi::ed in a final repor :o the NRC.

DETAILS

-Persons Contacted .

.During this-investigation approximately 50 individuals were contacted.

Twelve.CPCo personnel which included corporate engineering and quality assurance personnel as well as site management, quality assurance and quality control personnel. Thirty-two Bechtel personnel were contacted.

These largely consisted of site engineering,.quali:y assurance, quality n ,.c .a_. control, survey and labor supervisors and personnel in project engineering, quality assurance and Geotech at the Ann Arbor, Michigan office. . Three.  ;

individuals employed by U.S. Testing Company were also interviewed.  !

4 Introduction On August 2d,1978, the licensee informed the NRC Resident Inspector at the Midland site that unusual set:lement of_the Diesel Generator suilding (DG3) had.been detected through.the established Foundation Data Survey program. b'hile~the licensee regarded the matter as seri:us it was no:-c'ensidered to be reportable under the provisions of 10 CTR 50.55(e) until further da:a was obtained.

f'"

Following the acquisition of addi:icnal data from further surveys and

a. core boring program which was initiated on August 25, 1978, the t's- licensee concluded the mat:er.was reportable and so telephonically notified Region III on September 7, 1978. The notification was follcwed up by a series of interim reports the first of which was submit:ed :o Region III by letter dated September 29, 1978. Subse-quen: interim reports were transmitted by letters dated November 7, 1978 and January 5, 1979.

I' .

An inspection was conducted by Region III during :he period Oc:ober 24-27, 1978, to review the data then available; to ebserve the curren: condition af the structure; and, to review current activi:1es. Informa: ion regarding the inspection is centained in yRC Inspection Repor: No. 50-329/73-12; 50-330/78-12.  ;

On December 3-4, 1978, a meeting with SRR and Regice III represents:ives was held at the Midland site :o reviev :he status of the problem, :o discuss open' items identified in the aforemen:1oned inspection repor:

l. .and possible correc:ive actions.

indicated _that from his experience-he would have expected about 1/8" settle-ment. The July 22 data- showed a dif ferential settlement between various locations ranging'from'l/a" to a. maximum of 1 3/8". .He promptly instructed his survey personne11 toLresurvey to: determine whether the data was accurate.

The resurvey. confirmed the accuracy of the survey data. The Chief of Survey Parties reported the survey, results to the Bechtel lead civil field engineer.

The lead civil field engineer said that ~ 1n. July 1978 the settlement of a pedestal in the DGB was noted from surveys and about a week later a 1"l discrepancy.was noted shen scribes on the 0GB were being moved

^~'"~

up. He said that at that time he was uncertain as :o'whether actual set:1ement had occurred, the survey was in error or the apparent z discrepancy was a construction' error. He instructed the Chief of Survey Parties to check his survey results and to perform ' surveys more

- f requently :han the 60-day intervals required by the survey program as-a means cf determiaing whether-actual secclement had occurred and

-whether settlement continued.

The . Field Project Engineer was also informed of the apparent settlemen:

and.cencurred with the lead. civil field engineer's ac: ions. He said he had :oured the building at : hat time and he saw no visible indica: ions of stress which could be expected when unusual settlement occurs.

ja ~. ,

- The lead civil field engineer said the DGB was monitored for about a

month. He compared the amount of settlement being experienced with the

\s_ se: clement values reflected in Figure 2.5-48 of. the FS AR and did not

- consider it. reportable until those values were exceeded. When the sectiement did exceed those valuesLas indicated by survey data obtained on about August 18, 1978, he prepared a conconformance repor: with the assistance of QC personnel <

The July 22 survey data was :ransmi::ed by the si:e to the 3echtel Project Engineering office in Ann Arbor by a routine transmittal memo

~

da:ed July 26, 1978. The data was received at Ann Arbor, processed through document centrol on August 9, 1973, and was routinely routed

. :o the Civil Enginearing Group Supervisor. He sta:ed he did not review the data but placed a rou:e slip on it indicating those members of his group who should review 1:.

The engineer in :he Civil Group, who had established :he survey program and who was responsible for assuring i; was being carried out, sca:ed he reviewed the data and did ne: regard it as unusual. Ter that ressen he did not bring the ma::er to anyone's at:en: ion bu: merely routed 1- to o:her personnel in the civil group. The engineer respcnsible for the OGB said he did not see the da:a before the se::lement problem was iden:ified by the field in a nonconformance report.

\j With the issuance of the noncemformance report, No. 1482, on August 18, 1978, C?co was also informed of this condi: ion. Cn or about August 21, 1973, the NRC Resident Inspector was orally informed of the matter by C?Co. It was indicated at that time cha: al: hough CPCo regarded :he matter as serious, they'did not consider it to be reportable under 10 CFR 50.55(e).

Construction on the DGB was placed on hold an August 23, 1978 and a test boring program was initia ed on August 25, 1978. Af:er prelim-inary evaluation of soil boring data, a Management Correc:ive Action Report (MCAR), No. 24, was issued by Sech:el on Se.ptember 7,1978.

The MCAR stated that based on a preliminary evaluation of the data, the mat:er was reportable under 10 CFR $0.!5(e), 1, iii and Region III was so notified by telephone on that date.

The telephone notification was subsequen ly followed up by a letter dated September 29, 1978, from CPCo enclosing a copy of MCAR 2a and Interim Report 1 prepared by Bechtel.

On the basis of the above, it is concluded that ;n this instance the licensee co: plied with the reperting require:ents of 10 CFR 50.55(e).

[ t In a previous NRC Inspection Repor:, No. 329/78-12; 330/78-12, an

-! apparent inconsistency was identified between FSAR Table 2.5-14 (Summary of Foundations Supporting Seismic Categcry I and II Strue:ures),

Table 2.5-9 (Mini:um Compaction Cri:eria) and the site cens:ruction drawing C-15 (Class I Fill Material Areas) regarding the type of foun-dation material to be used for plan: area fill. Table 2.5-14 identifies the suppor:ing soil ma:erials for the Auxiliary Building D, E, F, and C, Radwaste Building, Oiesel Generator Building and Bora:ed %'ater Storage Tanks to be " controlled cc= pac:ed cohesive fill." Table 2.5-9 also indica:es :he soil type for " supper: of structures" :o be clay.

CPCo cuality assurance issued a nonconformance report QF-66, dated October 10, 1975, which stated that contrary to the PSAR statement (quoted above) Specification C-211 being implemented at the site required cohesionless (sand) material to be used wi:hin 3 feet of the walls of the plant area ltructures. The corrective action taken was I i for Bechtel to issue S AR Change Notice No. 0097 which stated, "The FSAR will clarify the use of cohesive and cohesionless so:ls for support of Class 1 structures." As noted above, the FSAR tables 2.5-14 and 2.5-9 once again stated that cohesive (clay) material was used for support of structures while :he construction drawing continued to permit the use of random fill material.

This investigation included efforts to ascertain whether procedures were established and implemented for the prepara: ion, con:rol and review of the technical criteria set forth in the safety analysis report (S AR) .

This included the role of both Bechtel and CPCo in the review of the SAR. Bechtel had established control of the SAR in precedure MED 4.22 (Preparation and Control of Safe:y Analysis Pepor: Revision 1, dated ~ June 20, 1974). The SAR prepara: ion and review flow chart requires the Engineering Group Supervisor (EGS) to reviev the originator's draf:

fer technical accuracy and compliance with the standard format guide.

Records indicated that Section 2.5.4 was origina:ed by :he 3echtel Geotech group on January 3, 1977. It was reviewed and approved for technical

(- f '"'N accuracy by an engineer in the civil projec: group on April 29, 1977.

I I No technical inaccuracies were noted in the documentation. The Civil

\~ - ECS advised that he did not personally review section 2.5.4 The designated engineer stated that in his review of :he sec: ion he was primarily concerned with the Auxiliary Building not the Diesel Genera:or Building. He said the review of FSAR ma:erial was performed by members of a group set up for this purpose. Not all of the content was checked since they relied to seme extent on :he originator. The author of See: ion 2.5.4 said he was not aware that changes regarding fill material had occurred since :he preparation of :he PS AR. It was tscer:ained that Field Engineerin; did.not reviev :he TS AR prior to its submi::al.

A par:ial review of the FSAR revealed that although Figure 2.5-48 indicates anticipated set:lement of the Diesel Generator Building during the life of the plant to be on the order of 3 inches. Section 3.3.5.5 (5: rue: ural Accep:ance Criteria) contains the fol'owing sta:e-I ment: "See:lemen:s en shallcw spread f:ctings founded :n compacted fil*.s are es:imated to be on the order of L/2" or less."

.See:1:n 3.S was prepared by Project Engineering. Geo:ech, who prepared Section 2.5, said they were unaware of :he presence of :he s:a:ement regarding 1/2" settlemen: in See: ion 3.3. The origina:or of Sectica 3.?

said that the above statement was taken from the Dames and Moore report submitted as part of the PSAR. Since the PSAR did not show any change.

in this regard, he assumed the statement was valid for inclusion in the FSAR. He said there was_no other basis to support- this statement.

\

CPCo also has an established procedure for the review and final approval

' of the S AR by procedure >TPM-13 dated June 23, 1976. Section 5.6 states j chat "CPCo shall approve all final draf t sections of the FSAR prior to ~

l final printing." Discussion with the responsible licensee representa-l.

cives for review of Section 2.5.4 indicated that a limited amount of

- cross-reference verification of technical content of the FSAR is

. perf ormed by C?Co.

The CPCo Project Engineer in Jackson stated that the review of drawings and specifications was an owner's preference kind of thing. No attempt was made to review all drawings and specifications since they did not have the manpower or expertise for that type of review. The staff engineers of the various -disciolines were asked to . indicate the drawings and specifications they wanted to review.

Regarding the review of the FSAR, he said that he had prepared a memorandum to the staff engineers stating the procedure that would be

followed in performing the review.

An examination of this memo, dated

/' \ July 28, 1976, showed that prime reviewers would perform a technical

( review, resolve comments made by other reviewers and perform the CPCo licensing review to assure compliance with required FS AR format and content.

As portions of the FSAR were received from Bechtel, C?Co sent comments to Bechtel. Following this review, meetings between Bechtel and CPCo were held to clearup any unresolved matters before each section was '

released for printing. A review of the files at CPCo relating to Section 2.5 and 3.3 showed that no comments were made concerning the above inconsistent and incorrect content. The apparent inconsistent and incorrect s tatements were act iden-ified during the review of the FSAR prior to submittal and the review procedures did not provide any mechanism ts identifv apparent inconsistencies between sections of the FSAR.

Based en the above, measures did not assure that design basis included in design drawings and specifications were translated into the license application which resulted as an inconsistency between the desi;n drawings and the FSAR. This is considered an item of noncompliance with'10 CFR 50, Appendix Y Criteri:n II*. (329/73-20-01; 330/73-20-01) e c

Effect of Ground Water in Plant Area Fill

The normal Final' plant' grade.will be established at elevation 631 ground water was assu=ed_to_be at ground surface prior :o construe:1on, approximately' elevation 603. The' surface of the water in the cooling water pond.will be at a maximum of approxi=ately elevation 627.

The Dames and Moore' report on Foundation Investigation submitted 'with PSAR Amendment No. 1, dated February 3, 1969, stated that,'"The ef f ect of raising :he water level to elevation 625 in the reservoirs will cause the normal ground water level in the general plant area to

' eventually rise to approxima:ely eleva: ion 625. However, a drainage sys:em will.be provided to maintain the ground. water level in the plant fill at elevation 603."

A suoplement to Dames and Moore report was ' submitted in ?S AR Amendment No . 3 ; d a t ed Augus t - 13, 1969. which changed :he above planning of a drainage system to control the ground water. The supplement states, "The underdrainage system' considered in the initial report has been elimina:ed; consequently 1:'is assumed that the greund wa:er level in the plant area'will. rise concurrently to approxima:ely elevation 625."

A 3ech:el soils consultant'theori:ed in a December 1, 1973, site eeeting

/ ) that if soils' beneath the diesel generater building had been ecmpacted

\s,,/ too dry of optimum, changes in moisture af ter placement :could cause the soils ~co settle.significan:1y. 'Therefore, the total effect of the 3round. water being permitted to saturate the plant fill material is undetermined at this ti=e. An evaluation of this condi: ion is'under review by the licensee. This i:em is considered' unresolved. (329/78-20-02; 330/78-20-02)

Review of Comcaction Requirements for Plant Area 7111

During the investigation a review of the his:ory of the esmpaction requirements.vas performed in order to determine whe:her :he compaction of the plant fill was implemented in cempliance with the commitmen:s in

?$AR, Amendmen:~ 1, da:ed February 3,1969, presented :he Oames and Yeare repor: " Foundation Investigation and'?reliminary Exeloracica for 3orrow-Pa t e r ials .

Exploration for Borrow Ma terials." Page 16 of this repor: lists :he recce ended minimum compaction cri:eria for sand stils and cohesive soils.

For the fill material for supporting s:ructures the minimum compaction is 85% relative density for sand and 100% of maximu density for clay as determined by ASTM D-69a_ odified :o require 20,000 f t-lbs. of compae:ive energy (equivalent to 95" of ASTM D-1557, Method D which provides 56,000 f:-lbs of compactive energy). Subsequent to the filing of Amend en: 3, no amendments were made to the ?SAR to indicate tha: the recommendations contained in the Dames and Moore report would not be followed or would be further =cdified.

^ ' ~ ' Bechtel Specificatien C-210, Secti:n 13.0 (?lant Area 3ackfill and Ber: 3ackfill) indicates the compa:: ion requirements for cohesive soil

( 13. 7.- 1) to'be "not less than 95* of max 1=um density as determined by ASTM D-1557, Method D" and for cohesionless soils -(sand) (13.7.2) :o be cc=pacted ":o not less :han 30* relative density as determined by ASTM D-2049. "

A 00=parison of the ?S AR. commitments to the specification requiremen:s shows that the Ocepac:ica conni::ents for cohesive soil (clay) were translated in:o the : ens:ructi:n specifica: ion i.e. 93*. of maxieue density using ASTM J-1557, Meth:d D (co pac:ive energy of 56,000 f:-lbs) .

However, :he ::=pactien ce==itten: in the ?SAR for cohesionless soil

W A review of Specification C-210 (specification controlling earthwork

~

' contract) beginning with Revision 2, dated. July 27, 1973, which was I issued for subcontract showed tha: i: contained conflicting sections relating to the plant area backfill compaction requirements.

LSection 13.7, Compaction Requirements, from revision 2 to the la:est revision of specification C-210. consistently- specified that the backfill

-in :he plant area shall be compacted to 95% of maximum-densi:y as deter-mined by ASTM 1557, Method D.

Section 13.4, . Testing Plant Area 3ackfill, of specifica:1:n C-210 con-

""" "## ained.:he_ statement : hat :es:s would be ' performed as set for:h in Sectien 12.4.5, Laboratory Paximum Densi:y and Optimum Mois:ure Centent, which in turn specified a lesser standard,--20,000 foot-pounds per cubic.

foot..which is commonly referred to as-the Bechtel Modified Proctor Density Test-(BMP). ' This is contrary-co the requirements of Section 13.7.

Section:12 of the specification' applies'to Oike and Railroad Embankment Construe:1on.

I:,vas also no:ed that this centrol inconsistency was reflected in the applicable Midland OA Inspec: ion Cri:eria, SC-1.10, Item 2.3(d) Compaction which sta:es "3ackfill material for the specified :enes has been compacted to' the required density as de: ermined by 3ech:el Modified Proctor Method" 2

f'^s and yet references C-210, Sec:fon 13.7 as the" inspection criteria.

The inconsis tency in control is fur:her indicated in Specification C-208-which defined the testing contract requiremen:s of subgrade materials, See: ion 9.1 (Tes:ing) required compac:1:n tes:s to be in accerdance w1:5 ASTM 3-L557 and only when directed was the 5M? compaction criteria to be used.

QC's interpretation was that;the field needed "co obtain 957 of maximum density by the modified Proctor method (ASTM'1537, Method D), wi:h no restrictions as to the method used to ebcain these results."-

2. Letter 7220-C-210-23,.datedJJune 24, 1974, (field Engineering :o construe: ion) responded to Item 1 abovec It states, "We have reviewed your June 10,_1974, IOM concerning compactive ef fort required'on. Zones 1 and 2 in the plant and berm backfill areas.

We agree with your interpretation; i.e. a 95% of maximum density is the acceptance criteria, and the' number of roller passes listed in Paragraph 12.S.1 does not' apply to plant and berm backfill. We

- feel the specification'is now clear and no FCR is required."

3. Let:er'3C3E-370, dated July 25, 1974, (field construction :o

. proj ect engineering) lists outstanding items requiring Project gr

v Engineering's action. This includes the question, "Is'the-95*

compaction required in.the plant area :o be 95% of Bechtel Modified or 95*. of ASTM-1557, Method D."

4. Letter BEBC-456, dated August 1, 1974, (Project Engineerin; :o Field Cons:ruction) states that Geotech is addressing the ques:ica

-posed in BC3E-370 (Item 3 above).

5. Memorandum from Geotech to Bechtel Field, dated September 18, 1974, responds to :he question raised in 3CSE-370 (Icem 3 above). It states- "It is our opinion :ha: all the compaction

- requiremen:s that are needed for Sone II material in the plant fill is as s:ated in 13.7 with the ex:ep: ion hat Tones 4, 4A, 5, 5A, and 6 ma:erials need no special compac:ive effort other than described in'Section 12.3.1."

6. Telecen da:ed Sep: ember 9,1974, .from R. Crete (Field Engineering)-

7. Telecon Consumers to Bechtel Engineering dated September 19, 1974, expressed Consumers Power Company concern about wha: they felt was a lack of control of compac: ion in the plant area fill. CPCo addressed the added_ responsibility this lack of control places on the inspector. Bechtel :old CPCo : hat it "was the inspector's job to make sure we got proper placement, compaction, etc."
8. Telecen dated Septe=ber IS, 1974, by Bechtel Field Engineering to Sechtel Project Engineering discussed compaction requiremen:s for specification C-210. It sea:ed, " Compaction acceptance is based on meeting an 'end produe:' requirement, i.e. 95* of maximum density only. No method of achieving this 'end product' is specified or is required. Rixford fully agrees with the above."
9. Telecon-dated October 7,1977, f rom Bechtel Field Engineering to Bechtel Project Engineering states, "QA has asked for clarification o f subject specification (C-210), See: ion 13 for plant area and berm backfill. See:1on 13.4 for :esting of materials refers to Section

.!2.4 and therefore, requires the Pechtel Modified ?rce:or Density Test for Compac:fon of cohesive backfill. See: ion 13.7 for compac-tien of the same materials refers to :ssting in accordance with ASTM D-1557 Method 0 Proc:or, w1:hou: specific reference :o Sechtel Modification." Sech:el Engineering responded to this question aa

/N follows: "This apparent conflict is clarified by Specification

('- ') C-203, Section 9.1.a, direction to the :esting subcontractor, which calls for ASTM D 1557 test for these materials and also allows Bechtel Field (the contractor) to call for the 3echtel Modification of tha: test. Either =eched is :herefore acceptable to project engineering."

10. Telecon da:ed October 7,1977, f ree 3echtel QA to 3ech:el Proj ec:

Enzineering questions, "Is :he intent of Paragraph 13.7 of Speci-fication C-210 that :he :es: be run to the 'Sechtel' modified proctor :est as is indica:ed in the FSAR Paragraph 2.5.4.5.3 and in respense to ::CR 33 ' Eh;ineering's response was "ves."

Various interviews were held wi:h Bech:el cons: rue: ion field en2ineers, C. C. Tes:inz personnel and Sech:el Ann Arbor Geotech and ?roj e::

b. -The required compaction and testing was always understood to be based on the "Bechtel Modified Test Method."
c. The required compaction and testing was always understood to be based on the standard ASTM 1557, Method D requirements,
d. A tacit understanding had been. established to use the techtel Modified Method, but to exceed this requirement by enough to'also satisfy the requirement of ASTM 1557, Method D.

It is apparent from the above four distinctly different understandings w 3. n .

of the compaction requirements, that the apparent confusion was not resolved. A member of the 3echtel QA staf f in Ann Arbor who had previously been a QA Engineer at. the Midland site said that QA audits of QC inspection' criteria did not identify the above inconsistencies.

This failure to-accomplish activities affecting the quality of the plant area fill in accordance with procedures is considered an item of noncom-pliance with 10 CFR 50, Appendix 3, Criterien V. (329/73-20-03: 330/78-20-03';

Review of Moisture Control p.ecuirements for plant Area Fill 7"'N Specification C-210, Section 13.6 (Moisture Control) requires moisture t control of the plant ' area fill material to conform to Section L2.6.

N The moisture control requirement in Section 12 6. .1 states , in part,

" Zone 1,.lA and 2 =aterial which require moisture control, shall be moisture conditioned in the borrow areas," and that " water concent during compaction shall not be more than two percentage points below optimum moisture content and shall not be more than two percen-

. tage points above optimum moisture content."

Contrary to the. above, Sechtel QA identified in 50-40 dated July 22, "Lw"" 1977, that "the field does not take moisture control tests prior to and during placement of the backfill, but rather rely on the moisture results taken f rom the in-place soil density tes ts."

The following is a summary of the documentation that followed the identification of the above deviation from specification C-210.

1. Letter 3C3E-l533R (dated August 15, 1977) field to pr: ject engineerin;

. states, "it was found that densities meetin; specification require-ments could be attained, irrespective of the use of moisture tests," and that " moisture tests were not used to :entrol backfill moisture." The field requested "that project engineering a7ree to acceptance of backfill materials installed in the past, alenz with the records'thereof, irrespective of the use of the meisture tests."

2. Letter BEBC-1859 (dated Sep: ember 30, 1977) responsed :o :he fields request in 3C3E-1533R. Engineering states, "It should be noted that it is ideal to control the moisture of backfill material at the borrow areas by conditioning" and that ":he procedure used to take moisture conceit . tests af ter compaction would not have direct impact on the quali:y of work." Engineering then agreed with the field request that " backfill placed prior to modification of testing methods to be accepted as is."
3. Telecen October 10, 1977, (3echtel OA Site :o 3ech:el Engineering, Ann Arbor)' indica:ed that , "there are no moisture requirements at the cime of density testing, only density requirement. The moisture requirement is prior :o compaction."
4. Telecon October 13, 1977, (Bechtel Engineering to 3echtel CA Site) changed what was indicated in the telecon on Oc:ober- 10, 1977, (Item 3 above) . Engineering then stated, "The moisture require-ment (+ 20 of optimum) is mandatory and must be implemen:ed at the time of pla:ement and testing." This is con:rary to what war stated en October 10, 1977.
5. Le::er SCBE-1669R (dated Novencer 18, 1977) once again is a field reques: to Bechtel engineering reques:ing, " written clari-

/'~m's fication of the 2% tolerance on backfill moisture content during

5. compaction."
6. Letter BE3C-1993 (dated December 15, 1977) provides engineering's response to SC3E-1669R reques:ing clarification of the mois:ure requirement. Engineering stated, "The mois:ure con:ent of the soil should be within 2! of optimum during placemen: and compaction.

Hewever, this property of the soil is not necessarily a measure of its adequacy after compac: ion."

7. Le::er 0-1631 (da:ed December 21, 1977) closes OA Action Reques:

50-40 (da:ed July 22, 1977) which firs: iden:ified the mois:ure concrol deficiency.

S. Telecon (dated April 7, 1973) from Field Engineering and Ouali:y Con:rol :o Projec: Engineering once again reques:s them ":o clarify 3EBC-1993" (December 13, 1977), Item 6 abeve. Two situa: ions were presen;ed to engineering as follows: (a) The mois:ure sample

aken f res :he borrow area at the start of :he snif: is acceptable, however, the mois:ure tes: taken in conjunc: ion wi:" Jae denst:y tes: fails while compac:1on was a::ained; and ,01 The nois:ure sample taken ft:m :he borrow ar2a at the s: art of :he shif: fails and :he material is condi:i ned :o meet mots:ure con:en: required,

v however, the moisture test later fails at the time the passing compaction est is taken. Engineering responded, "the above :wo situations are acceptable as is." This response is contrary to the direction previously given in :elecon dated Oc:ober L3, 1977 (see Item 4 above).'

9. Letter GLR-249 (April 16,1978) is a Sechtel Si:e OA request to Project Engineering to resolve the moisture content situation and "to provide clear direction for :he control of moisture concent." QA recommends "one possible solution would be to delete the requirement to con:rol :he moisture content and rely

~~~~~

on the compaction requirement only for completion of soils work."

10. Letter 3E3C-2236 (June 1, 1978) was Project Engineering's response to GLR-249 (Item 9 above) . It states, " moisture content is not necessarily a measure of a soil's adequacy to act as a founda: ion or backfill material," and tha: " soil with the specified densi:y following compaction would no: be rejec:ed on the basis : hat its moisture content was not contr:lled in the borrow area."

Based on the reviews of documentation, mois:ure controi had no'. been implemen:cd as the specification required. In addi: ion, the cat:er had not been resolved for the period of time from the issuance of QA e' 's Action Request SD-10 on July 22, 1977, until June, 1973, during which (x,_ ) time soils saf ety-related work continued.

/

According :o the licensee, although coisture centrol was not s:rie:ly followed in accordance with specifica:1on requirements, final densi:y tests were used as a basis for acceptance of soil placement.

As poin:ed ou: to the licensee, moisture control is a required cen:rol point to assure attainment of percent compac: ion specified in specifi-cation C-210.

This failure to assure that conditions adverse to quality are pr:mp:1y iden:ified and corrected to preclude repe:i: ion is censidered an item l of noncompliance with 10 CFR 50, Appendix 3, Criterion XVI. (3.9/73-l 20-01; 330/73-20-04) i Revies of Subtrade ?recara: ion for plant Area ill The Oates and ! bore repor: on fcunda: ion investiga: ion Aubmi :ed wi:h PSA?.

3.1/2 feet of natural soil or similar cover remain in place over the final subgrade or overlying the med mat. This layer of protective material is necessary to prevent the softening and disturbance of subgrade soils due to frost action." The licensee indicated :ha:

' instructions for winter' protection of foundation excavations were trans-mitted-by sketch C-271.

The Dames and Moore report also s ated, "If filling and backfilling operations are discontinued during periods of cold weather, it is recommended that all frozeh soils be removed or recemoacted prior to the resumption of operations."

After review of the applicable sections of specification C-210 (i.e.

Sections 12.5.1, 12.10, 10.1 and 11) the inspector has determined that the Bechtel specification did not provide specific ins: ructions for removal or recompaction of frozen /: hawed soils upon resumption of work after the winter period to preclude :he' effects of frost action on the compacted subgrade materials.

This failure .to assure that regulatory commitments as specified in the license applicatten are translated into specification, drawings or instrue:1ons is considered an item of noncompliance with 10 CFR 50, Appendix 3, Criterion III. (329/78-20-05; 330/78-20-05) s

Review of Calculations of See:1ement for Plant Area A review of the settlement calculations for the structures in the plant area was performed during a visit to the 3echtel, Ann Arbor Engineering of fice. Soecific at:ention was given to structures

- founded on plant area " compacted fill." The following specific findings were made:

1. FS AR, Section 3.3.4.1.2. (Diesel Genera:or Building) indicates the foundation 'of the DGB to be continuous footings with inde-pendent pedestals for each of the Diesel Generators. Con:rary to the structural arrangement described in the FSAR, the settle-ment calculations for the DC3 were performed on the premise : hat the building and equipment loads would be uniformly distributed to the foundation matertal by a L34' x 70' foundation mat. The settlement calculations were performed between Augus: 1976 and Cetober 1976 by Sech:e1 Geo:cch Division.

Discussion wi:h the Geotech F.ngineer who performed the set:lemant calculations indicated that he had not been informed of the l

/',_s} design change of the foundatien un:11 late August 1978 when :he l excessive settlements of :he DGB and pedestal becare apparent.

2. FSAR Figure 2.5-47 indicates the load intensity for the OG3 :o be 4 KSF (4000 lbs. per sq. f:.); however, the se:tle=en: calculations reviewed indicate a uniform load of 3 KSF (3000 PSF) . This appears to be a conflict between the FS AR and set:1emen: calculattens.

4 During a review of 'the settlemen: calculations, it was observed that the ec=pression index (Cc ) for the compacted fill between elevations 603 and 634 in the plant area was assumed to be 0.001 (esticate based on experience). FS AR S ee:1:n 2. 5. 4.10. 3. 3 (Soil Paraceters) indicates the soil compressibili:y parame:ers used in the set:lement calculation are presented in Table 2.5-16.

This table indica:es that for the plant fill eleva: ions 603 to 634, the compression index used was 0.003. Contrary : the FSAR value, 0.001 was used in the settlemen: calculations reviewed.

This value is direc:ly used :o deternine :he estimated ultirate settlement of structure supper:ed by plant fill caterial.

supporting safety-related structures and therefore per:inent to the, j current secclements being experienced by the Diesel Generator Tailding, i

.The following are the events rela:ing :o the set:lement of the Admini- l stra:icn Building footings.

During.the end of August, 1977, a Sechtel field engineer observed a gap between a slab and the grade beam of the Administration Building. On August 23, 1977, a survey was taken of the settlement. The results indicated that the footings supporting the grade beam had experienced settlement ranging f rom 1.32" (north side) to 3.43" -(smh. side) .

This set:lement took place between July lf77; and :he enc of August

"" 1977. The footings were supported by " random fill" (Zone 2 materfgl).

i The concrete footings on the order of 7' 6" by 7' 6" by l' A" deep were removed along with the grade beam. The random fill material was also removed, _According to C. S. Testing personnel, it was observed during excava:icn of the fill' material.that there were voids of 1/ 4" to 2" or 3" within the fill and these were associated wi:h large lumps of unbroken clay measuring up to 3 feet in diane:er.

The Civil Field Engineer assigned responsibility for plan: fill work said': hat, al: hough he was no soils expert, it was.his opinion that :he

" problem was caused by the presence ef.peckets of water due to drainage from nhe steam tunnel. The Lead Civil Field Engineer also indicated

'f a crainage problem caused the Administracien Building footings settle-

.-\ . ment. They were,-however, unclear'as :o how the wa:er pockets ware l . formed, i.e. whether they were formed as the fill was being placed or.-

l hov they could develop after the fill was compac ed.

The excavated fill was replaced wi:h concrete and the design of l- individual footings was changed :o a con:inuous spread foo:ing i design for suppor: of the building.

As a resul: of the set:lement of :he Administration Building footings q a :stal ei seven borings were taken of which !ive were in the Admini . 1 scre:ica Building area, one in :he Evapora::r Building area and one sou:h of the Diesel Generator Building, in the Admints:ra:ica Buildinz area the f oundation ma:erial was found to be "sof t" wi:h " spongy char-acteristics." The two o:her borings did no: indica:e unusual ma:erial proper:tes in :ha: the blow counts were reasonable. *hese borings were taken in September 1977. 1 The licensee indicated : hat repor s from Sechtel concluded : hat the primary cause of :he settlemen: in the Admin?s:ra:ica Suilding urea 4 was insuffician: compac: ion of :he fill.

han maximum density.

Bechtel personnel, including the Civil Group Supervisor, Project Engineering,' the Field Proj ec: Engineer, :he Lead Civil Field Engineer,

.cnd the Chief Civil CC Inspector, all sea:ed tha: the Administration Building focting se::lement was regarded as a locali:ed orchlen. The ques: ion as to the adequacy of the entire plant area fill did no: arise even : hough the following similarities existed between :he Administration Building area and rest of plan: fill; (a) same soil specifica icn applied, (2) saee caterial (random fill) was used and (3) same centrol procedures and selection of laboratory compactica scacdards was used. The Diesel Genera:or 3uilding area required even more fill than other safety-related stru::ures since its base is located a: a higher elevation than the ethers.

Review of Soils Placement and Inscection Activities for ?lant Area ?'ill-A subcontractor, Canonis Cons:ruction Company, South Haven, Michigan, performed the major portion of the earthwork at the Midland site.

Although Canonie was primarily engaged to construct the cooling pond

' dike, they also performed mos: of the plant area fill work. 3echtel, howeve'r, also performed plant fill work prior :o and.af:er Canonie lef:

the site in mid-October 1977. The las: Canonie' daily 0A/QC fill placemant report is dated October 16, 1977.

A'ccording to Canonie OA/QC records :he first fill in the DG3 area was placed in late October and early Move ber 1975. No fur:her fill was placed in :he area until July 1976. After cha: :tre, fill work in the

+ area'vas interspersed with-soils work in other areas.

Tihile it would be difficult to identify :he soil work performed by Sech:el versus. chat perfor ed by Canonie, records reviewed indicated that mest of the 3echtel work was done during the latter part of 1976 and continued through 19i7 and 1978. Although most of :he 3echtel work

( related :o placing sand around piping and ducts after : hey.were laid and placing sand adjacen: :o walls, some motori:ed work compacting clay fill was also done by Bechtel.

j' Regarding the plant fill work' performed by Bechtel, C?Co Audi: Report No. ?-77-21 dated' June 10, 1977, identified a number of deficiencies l-which reconcended the corrsetive action to be as follows: (1) "the foremen directing'the soils work should be instrue:ed as ;o the required mois:ure con:en: limi:s" and (2) "the foreman directing the soils work should be instruc:ed as to the correct tes: frequency requiremen:s." In:erviews wi:h two such Bechtel fore =en confirmed :he fac: :ha: : hey were direc tag soil opera:icns. They indi:ated they received : heir ins: rue: ton regarding 11!: :hicknesses and tes:ing requiremen:s verbally fro field engineering :hrough a general foreman.

Based'en the above, the soils activities were not accomplished under the  ;

continuous technical supervision in accordance with Bech:el design cri-

aria.. This. failure to provide a qualified soils engineer Oc perfore 1
technical supervision for activities affecting quali:y as required by I specifications and :he PSAR'is considered an 1:a of~ noncompliance wi:5 10 CFR 50, Appendix 3, Criterion V. (329/78-20-09; 330/78-20-09)

The forenen indicated that Bechtel Field Engineers and QC inspectors were rarely in'the areas where soils activities were going on. The forecen )

decided when and where :ests were :aken. The locations of ests were l approximated by pacing or visually escitating dis:ances f ece columns or building walls. Lift thicknesses were determined visually, usually without the use of. grade stakes.

Soils, testing services are provided by C. S. Tes:ing Company based on the requirements of Specification C-208. The two C. S. Testing tech-nicians who said : hey performed an estimated 90% of the seil testing during the years 1975-77, indica:ed : hat they rarely saw a Sech:el field engineer or QC inspector _in-the areas where plan fill ac:ivities were going on. One :echnician said he could recall only one occasion when a QC. inspector was present when he cock an in-place density es:. The other technician estica:ed he,had con:ac: wi h a QC inspec:or in the field abou: ence a conth. A Sechtel QC inspe::or, however, was assigned to the testing laboratory on a full-time basis.

or a labecer if :he foreman wasn't there. Semetimes, however, a foreman was not familiar vi:h the area in which he was'werking and the loca:1cn was not provided until so=ecime af:er the :est. It became necessarv en l occasien to wi:hhold':est resul:s as a means of ge::ing the test loca;ien.

The technicians fur:her advised tha: rarely did a 3echte! QC inspe::or request a test. Normally, labor foremen requested : hem. On oc:asion a technician passing :hrough an area would be asked by a foreman if

. .a test should be'taken. Upon concle:icn of in-place ces:s, :he resul:s were usually coe=unicated :o :he foreman directing :he werk. Tes:

some occasions. A 3echtel foreman confirmed that densi:y tes:s were on occasion taken wnile it was raining. While :his is no: contrary to the specification instructions, it is contrary to standard practice.

C. S. Testing personnelindica:ed that when moisture was added, :he procedure did not include blending the material which resul:ed in mushy seams. It is commonly accepted good parctice :o disc the fill after soraying it with water to add needed moisture. A 3echtel foreran stated that if moisture was needed they compacted 6" then sprinkled i:

and : hen added ano:her 6".

The field engineer who was assigned responsibility for plant fill work s:a:ed he did not spend full time on soils work since he aise had responsibill:y for two strue:ures, the steam tunnel and general yard work. He said he tried to ge: cut to the area where fill vork was being done once a day. Some :imes he did and sometimes he did no:,

He indicated it was his impression that :he CC Inspector responsible for :he soils work on :he day shift vist:ed those work areas ence or

wite a week. He confirmed that only oral instrue:1cas were furnished to the foremen whom he felt were conscientious. The main proble: he experienced with the foreman was maintaining pr:per lif: :hickness.

The QC inspecter who was primarily responsi'rle for the plan: fill verk

( p-'s is no longer employed by'3echtel. The QC inspec:or who was respensible f for :he plan: fill work on :he nigh: shift stated that he :ried :o devo:e A/

) about one hour a nigh: to the plant fill ac:ivities. He indica:ed : hat during 1976-1977 there was much emphasis being placed on cadwelding and f rebar work and it was necessary to spend the majcrity of his time on l  : hose activities. He maintained that he did have fairly frecuent contac:s with the technicians who performed the in-place density :ests, par:ic-ulc ty when :est failures occurred. He indica:ed it was nis irpression tha: the labor foremen were direc:ing fill pla:enent adequa:ely.

NOTICE OF VIOLATION Consumers Power Co. Docket No. 50-329 Docket No. 50-330 As a result of the inspection conducted on December 8 - 11, 1980, and in accordance with the Interim Enforcement-Policy, 45 FR 66754 '

(October 7,1980),- the following violations were identified:

1. 10 CFR 50, Appendix B, Criterion XVI states, in part, that " Measures shall be established to assure ,that conditions adverse to quality such as. . . deficiencies. . .a re promptly . . . corrected. The measures shall assure that the cause...is determined and corrective action taken to preclude repetition."

Consumers Power Co. QA Program, Policy No.16, corrective action states, '

in part, that " corrective action is that action taken to correct and pre-clude recurrence of significant recurrence of significant conditions adverse to the quality of items. . . Conditions or trends observed or identified which are adverse to quality are considered for corrective action..."

h Tle "FSAR Re-review Procedure" instructions for Block 8 requires that "t he engineering design documents against which the FSAR review package

is to be reviewed are listed by the primary review engineer."

CPCO Audit No. M-01-53-0 states, in part, "the following significant items were revealed by this audit...in many instances not all of the design documents were listed as required by the instructions for per-forming the re-review."

Contrary to the above, CPCO did not initiate preventive action to pre-clude repetition of not identifying design documents for the remaining re-review packages as evidenced by the inspectors review of other Fr.AR re-review packages which did not include all of the design documents.

In addition, interviews with some of the primary reviewers indicated that they were not reviewing the FSAR for technical accuracy against references at the end of the FSAR chapter as required by the procedure.

Based on the above, the adequacy of the FSAR re-review is in question.

This.is a Severity Level IV violation (Supplement II).

l 2. 10 CFR 50, Appendix B, Criteria III, states, in part, that " Measures shall be established to assure that... design bases ...are correctly translated into specifications. . .and for the identification and control i of design interfaces...these measures shall include the establishment i

O of procedures. ..for the review of documents involving design interfaces."

Consumers Power Co. QA Program, Policy No. 3 states, in part that "Each group.. performing detailed design translates the applicable regulatory requirements... design criteria into design documents, such as specifica-tions... procedures. The design organization... establishes and controls the interface with other-design organizations.

a. Bechtel EDPI 4.25-1, Section 6.1, states, in part "Each originating design group shall maintain a log of all documents which are routed to personnel external to the design group. These logs shall be re-tained.. .providing visibility of the projects design interface control.

Contrary to the above, Bechtel Civil Project Engineering group did not maintain a coordination log of specification and specification

. change notices as evidenced by our review of soils related specifica-tions C-211 and C-210.

b. ANSI N45.2.11, Paragraph 4.1 requires that applicable design inputs are correctly translated into specifications drawings, procedures or

. Instructions. In addition, Paragraph 7.0 requires that documents including changes are reviewed for adequacy.

Consumers Power Co. 's 50.54(f) response, Page I-17, Paragraph 4(a) required that specification change notice (SCN)-9004 be issued to.

h) require a laboratory compaction test to be performed for each field density test. SCN-9004 was initiated on 4/13/79.

V Contrary to the above, Revision 16, dated 8/24/79, to the present Revision 20 of specification C-208 did not correctly translate l SCN-9004 as a requirement into the specification. Revision 16 permitted laboratory density tests to be performed at a frequency as determined by the geotechnical engineer rather than for each field density test performed.

l

c. ANSI N45.2.11, Paragraph 8.2 requires that design changes be reviewed and approved by the same groups or organizations which reviewed and approved the original design documents.

Consumers Power Co. 50.54(f) response, Page 23-11 committed to revise existing design control measures and require design interfaces on s design changes. EDPI 4.25.1, Revision 7 added Section 4.2 which states, "It is the responsibility of the originator of a design change to effect -

coordination of the change with all groups which reviewed and/or used the original or subsequent revisions of that design document."

Contrary to the above, Revision 8 to EDPI 4.25.1 permits the group

! supervisor to waive the design interface requirement by adding to Section 4.2, "as determined by the group supervisor of the discipline which originated the document." Revision 8 does not establish adequate measures as required by ANSI N45.2.11 or as committed per 50.54(f)

1. Background Meetings were held on February 23, 1979 and March 5, 1979 at the NRC Region III office in Glen Ellyn, Illinois to discuss the circumstances associated with the settlement e,f the diesel generator building at the Midland facility. This discussion uas part of the investigation conducted by Region III as documented in NRC Invetsigation Report No. 50-329/78-20; 50-330/78-20, dated March 22, 19/9. Representatives i of the NRC staff from headquarters attended the meeting on March 5, L 1979. The staff stated that it's concern was not' limited to the
narrow scope of'the settlement of the diesel generator building, but

! extended'to various buildings, utilities and other structures located in and on the plar.t area fill. In addition, the staff exprer. sed p concern with the Consumers Power Company Quality. Assurance Program.

Under the authority of Section 182 of the Atomic Energy Act of 1954,

['~'}

( ,j as amended, and Section 50.54(f) of 10 CFR Part 50, additional in-formation was requested regarding the adequacy of the fill and the quality assurance program for the Midland site in order for the Commission to determine whether enforcement action such as license modification, suspension or revocation should be taken. Question 1 of the 50.54(f) letter dated March 21, 1979 requested information regarding the quality assurance program. On April 24, 1979, Consumers Power Company submitted the initial response to the 50.54(f) request, Questions 1 through 22. As a result of the NRC staff review of Question 1, the NRC concluded that the information provided was not sufficient for a complete review. Subsequently, on September 11, 1979 the NRC issued a request.for additional quality assurance information (Question 23). On November 13, 1979, Consumers Power Company submitted revision 4 to the 50.54(f) responses which included response to Question

23. As a result of the Region III investigation report and CPC0 responses, the NRC issued an Order modifying construction Permits No. CPPR-81 and No. CPPR-82, dated December 6, 1979. The latest revision to Consumers Power Company response to the 50.54(f) request is revision 10, dated November 21,-1980.
2. Purpose of Inspection The inspection was conducted at the Bechtel Power Company Ann Arbor, Michigan offices on December 8-11, 1980 to verify implementation of the specific commitments and action items reflected in Consumers Power Company response to 10 CFR 50.54(f) Questions 1 and 23 with the exception

of those areas where completion of commitments has not been satisfied as of this time.

The inspection was divided into the following areas:

a. A review of CPCo response to Question 1, Part (a) and Question 23, Part (1) regarding the identification of the specific quality assurance deficiencies that contributed to the soils problem, including the root cause of the deficiency, remedial action in the soils area, the programmatic and generic corrective actions as committed to in the response,
b. A review of CPCo response to Question 1, Part (b) and Question 23, Part (2) regarding the provisions to be implemented to preclude areas of contradictions between the PSAR, FSAR and design docu-ments.
c. A review of CPCo response to Question 1, Part (c) and Question 23, Part (3) regarding the programmatic and generic corrective actions to provide confidence that quality assurance deficiencies do not

-(or will not) exist in other areas.

The following sections of this report discuss the results of the review of the above areas of CPCo response to Questions 1 and 23.

3. Review of Question 1, Part (a) and Question 23, Part (1)

The identification of quality assurance deficiencies that contributed to the soils problem was discussed in Question 1, Part (a) and Question 23, Part (1). Concumers Power Company identified the root cause of the deficiencies, the remedial measures in the soils area, and the programmatic and generic corrective action to preclude further recurrence of the deficiencies. CPCo complied a list of specific action items that would have to be accomplished in order to satisfy the commitments made in response to Questions 1 and 23 of the 50.54(f) request.

Attachment No. I provides an action item tracking system which includes the action item description and reference and the status and documenta-tion verified by the NRC during this inspection.

Those action items for which CPCo commitments have been accomplished are identified as being " closed"; items identified as "open" either have not been completed by CPCo or the action taken was considered insufficient.

Question 1 provided 26 action items of which the NRC verified 18 had been satisfactorily accomplished while 8 remain open. Question 23 provided 57 action items of which 34-were determined to be satisfac-torily accomplished while 23 remain open.

O The following are NRC findings regading the implementation of certain t, CPCo commitments.

w

a. Action items 23-5 and 23-38 as identified in Attachment No. I provided commitments to examine current procedures and practices for the preparation and control of the FSAR in view of past experiences. CPCo committed to procedural changes to existing engineering department procedures.

Seven Bechtel procedures were examined and revised to clarify l design control procedures for the FSAR. Engineering Department Procedure Instruction (EDPI) 4.25.1, Design Interface Control, was revised by Revision 7 by including section 4.2 which states, "It is the responsibility of the originator of a design document change to effect coordination of the change with all groups which reviewed and/or used the original or subsequent revisions of that design document."

Subsequently, Revision 8 to EDPI 4.25.1, changes the above by adding to the end of the statement, "as determined by the group i supervisor of the discipline which originated the document." The originator of Revision 8 stated that the intent was that only technical changes have to be interfaced while editorial changes would not necessarily require this interface control. The pro-l cedural change, however, does not reflect the intent and permits l

ld

- lp the group supervisor to waive interface control for any changes Vl as evidenced by inspection finding in Paragraph 3(b) of this report. The engineering procedures EDPI 4.25.1 does not satisfy CPCo commitment made to the NRC in response to Question 23, subsection 3.3, page 11 and identified as action item 23-5 of Attachment No. 1.

This failure to provide adequate design interface control is considered contrary to 10 CFR 50, Appendix B, Criterion III as described in the Notice of Violation. (50-329/80-32-01; 50-330/

80-33-01).

b. Engineering Department Procedure Instruction, EDPI 4.25.1, Section 6.1 requires that, "each originating design group shall maintain a log of all documents which are routed to personnel external to the design group. These logs shall be retained . . .

providing visibility of the projects design interface control."

It was determined based on a review of specification C-208, Revision 20, Materials Testing Services, Section 9, Soils Testing and C-211, Revision 12, Technical Specification for Backfill, that the civil project engineering group is not maintaining a complete coordination log of specifications and specification change notices.

Interviews with cognizant Bechtel personnel indicated that it is up to the originator of the document to transmit the design docu-r ment to the coordinator clerk to log it in as being interfaced It was determined from reviewing the

( ])

V with the appropriate groups.

interface log that the originator of the documents are act aware of this requirement and documents are not being interfaced with other design groups as required by the procedure. In addition, Regulatory Guide 1.64, Quality Assurance Requirements for the Design of Nuclear Power Plants and ANSI N.45.2.11-1974, Section 10 requires design interface records to be maintained.

l This failure to maintain design interface and coordinator control l is considered contrary to 10 CFR 50, Appendix B, Criterion III as described in the Notice of Violation. (50-329/80-32-02; 50-230/

80-33-02).

c. Specification C-208, Revision 10, Section 9 regarding soil testing requirements was reviewed for technical content. It was determined that the specification was not adequate as written. The following specific findings were identified.

l (1) CPCo was identified in Question 1, Appendix I, Page I-13, Paragraph A.4(a) that the subcontractors test procedures for soil testing service were inadequate; specifically, U. S. Testing procedures did not provide for developing and updating a family of proctor curves used to compare in-place l

field density tests to maximum laboratory standards. CPCo committed to the remedial action on Page I-17, Paragraph 4(a) i

[

.A .

t ) which states, " Selection of proctor curves will no longer be 1

(/ a problem because each field density test will be accompanied by a separate laboratory standard compaction test which will provide a direct comparison." It was also stated that SCN-9004, dated April 13, 1979 was issued to require the above. I It was determined _ that SCN-9004 was issued as cossnitted; however, during Revision 16, dated August 24, 1979, of specification C-208, the civil project engineer failed to include the above requirement and instead revised Table 9-1 to permit the frequency of the laboratory test to be "as directed by the on-site geotechnical engineer" rather than for each field density test.

This does not comply with the commitment made in 50.54(f) response to Question 1. This occurred because adequate design interface controls had not been implemented as required by ANSI N 45.2.11.

There was no evidence that the geotechnical group had reviewed or approved the revision to the specification.

This failure to provide adequate design interface control is considered contrary to 10 CFR 50, Appendix B, Criterion III as described in the Notice of Violation. (50-329/80-32-03; 50-330/

80-33-03).

(2) Specification C-208, Section_9.1.1 should be reworded to (q) remove confusion which exists about the word " compaction".

U This section should read: Modified proctor tests on cohesive material shall be performed'in accordance with ASTM D 1557, Method D.

i (3) Section 9.1.3 (first paragraph) does not specifically indicate how ASTM D 1566 has been modified by t! SBR DES E-24.

In addition, why does the specification prohibit the use of

the nuclear density device for measuring in place field I density? This device is an industry accepted method with a standard ASTM designation.

(4) Section 9.1.3 (second paragraph) assumes a specific gravity of 2.75. The actual specific gravity should be known and used as is the industry practice.

(5) Section 9.1.3(c) should also include: if the results still plot to the right of the ZAV curve the test should be rejected and a new density test performed.

(6) Section 9.1.3(d) uses the phrase 101% compaction. This should read 101% of maximum proctor density. This section also permits the on-site geotechnical engineer "to evaluate" the results of tests that exceed 101% proctor density for cohesive material and O

[

\

105% for cohesionless material. This section should include the ' qualitative acceptance criteria and/or instructions to be

~

used for the basis of this evaluation.

The above' items 3(c) 2, 3, 4, 5 and 6 are considered unresolved items pending a review of CPCo response to each item. (50-329/

80-32-04; 50-330/80-33-04).

d. Specification C-211, Revision 12 regarding backfill work activities was reviewed for technical content. It was determined that the specification was not adequate as written. The following specific items were identified.

(1) Section 8.1 does not specify the type of material to be used

'beneath Category I, safety related structures. This should be included in this specification.

(2) Section 8.1.1 does not specify the type of material to be used around pipes and duct banks. The specification should specify or refer to appropriate instructions.

~(3) -Section'8.3.2.(third paragraph) states, "the uncompacted lift thickness of the backfill material shall be determined by the on-site'geotechnical soils engineer . . ." The on-site soils. engineer should not have to determine the lift p thickness when Attachment No. I to specification C-211 specifies the requirement for each type of equipment based

(-}

on equipment qualification tests.

(4) Section 8.5.2 permits the use of rubber-tired rollers to compact structural backfill and sand. Attachment No. I to specification C-211 does not indicate rubber-tired rollers as having been qualified and rubber-tired rollers should not be used to compact structural backfill and sand.

The above items 3(d) 1, 2, 3 and 4 are considered unresolved items pending a review of CPCo response to each item. (50-329/80-32-05; 50-330/80-33-05).

4. Review of Question 1, Part (b) and Question 23, Part (2)

The provisions and the procedures to be implemented to preclude conflicts between PSAR, FSAR and design documents was discussed in response to Question 1, Part (b) and Question 23, Part (2). Consumers Power Company included in their response a procedure entitled, "FSAR Rereview Procedure" to be implemented to accomplish this commitment.

Action-items. 23-1, 23-44 and 23-44(a) as identified in Attachment No. 1 provided the commitments to be implemented to assure FSAR accuracy. The following are the NRC findings regarding the implementation of these Coumlitments .

[ It.was determined that, in general, consultant reports were not attached Q to the FSAR. However, the complete. text of a consultant report prepared by Weston Geophysical Engineering Company was found as an attachment to the FSAR and included in the FSAR, as Appendix 2C. Therefore, the CPCo .

response which states, " Consultant reports were not attached to the FSAR, l but portions of consultant reports were extracted and incorporated into ,

the FSAR text itself" (re: Question 23, Page 23-7) is not correct. I CPCo also stated that the FSAR was rereviewed against design documents

-such as consultant reports for conflicts.

It was determined that -verification of portions of consultant reports incorporated into the FSAR have been adequately reflected in design  ;

documents has not been satisfactorily accomplished. FSAR Rereview Pro-cedure, Revision 1, dated March 13, 1980, Subsection 2.1.3 states that each FSAR section'should be carefully reviewed against design documents

. . . as a minimum, the following should be checked . . . references at i the end of the FSAR chapter. The procedure also requirec in Item 8 that engineering design documents against which the FSAR review package is to be reviewed are to be listed by the primary review engineer in .

Block 8 of the FSAR rereview form. A review of FSAR packages Nos. 9474, 9473, 9472, 9471, 9096, 9097 and 9098 indicates that no design documents other than a few drawings were identified and listed. Numerous reports were referenced throughout the FSAR text of these sections, however, they were not recorded as required in Block 8 as being reviewed for consistency with the FSAR text.

(,) An' interview with a Bechtel cognizant primary review engineer indi-cated that he physically checked the references to make sure that they agreed with.the FSAR text. Subsequently, after the NRC inspector found an apparent discrepancy between the FSAR text and one of the references, the Bechtel reviewer indicated'that he did not check the text of the references, but merely checked the reference for consistency of subject matter, i.e., title vs. sentence content not technical substance vs.

a FSAR statements. Another cognizant Bechtel primary review engineer indicated he could not check references in his section because he was not qualified to review the technical matter in this area. He indicated that he relied on the Bechtel Geotech group (the interface reviewer in Block 11) to verify the references. Discussions with a Geiotech reviewer indicated he did check reports for consistency with the FSAR, but did not list them in Block 8 as required.

After this was determined, the inspector was informed that a CPCo interim audit No. M-01-53-0, dated March 1980, identified the same problem concerning the lack of identifying design documents in Block 8 of the FSAR review form. At this time approximat'ely 600 of a total 'of 900 FSAR rereview packages had been completed. However, no corrective action was taken. CPCo final audit of this activity, audit No. M-03-202-0, dated November 1980, once again identified an

. unresolved item, URI-3, regarding this same problem. The FSAR rereview is now complete and the unresolved itesi was pending resolution as of the date of this inspection.

/ Cognizant individuals indicated that.one of the reasons why documents 4 s were'not listed.in Block 8 was because there was not sufficient space.

An interview with the preparer of the FSAR rereview document indicated

'that the. intent of. Block.8,'and it's instructions,-was to list all of the design documents to which the FSAR section was, reviewed against in .

order to assure there were no'more conflicts between design documents  !

and the FSAR text. .._

Based on the-above, it was determined the CPCo failed to provide l

adequate corrective action with regard to the identified audit results.  !

This is considered contrary to 10 CFR 50, Appendix B, Criterion XVI, as described in the Notice of Violation. (50-329/80-32-06; 50-330/80-33-06).

Due to this finding, CPCo implementation of the specific commitment l as discussed in response to Question 23, Part (2) has not been accom- .l plished and the adequacy of the FSAR rereview which has been completed  !

is questionable. j J'

5. Review of Question'1, Part (c) and Question 23, Part (3)

CPCo and Bechtel'have performed a detailed re-review of specifications, installations, and construction inspection plans, procurement documents, inspection.and test procedures,: including the results of inspections and tests to determine the completeness and accuracy of documents and the acceptability of hardware. In this regard, the IE inspection activities involved ~a review and evaluation of activities associated

/'Y' with'the above re-review actions and included discussions with main participants in the re-review effort. The following is a summary of this inspection.

a. .CPCo and Bechtel were able to demonstrate that an extensive

- re-review of specification,--inspections and test procedures, and documents associated with procurements were conducted with mean-ingful results. The. documents were evaluated by CPCo and Bechtel l to assure that the necessary tolerance call outs and quality l requirements were specified; that the qualification requirements were adequately called out and met; that there were sufficient specificity provided in the documents; and that there were the necessary inspection requirements specified. In addition, the completed documentation was evaluated to determine that technical i and quality requirements were met in an acceptable manner.

Areas that were found deficient resulted in revision and improve-ment to procedural controls and specifications. Hardware suspected {

of not meeting quality requirements were re-evaluated by engineering

,{

l and quality assurance to determine their accept, repair, or reject

!= status. .

Throughout this particular IE inspection effort, specifications, procedures, and instructions were reviewed and a determination t made that revisions and improvements were accomplished.  !

' V) b.

The improved trend analysis and corrective action program estab-lished by CPCo and Bechtel was evaluated and found acceptable.

. 1 It is expected that this program will prove effective in detecting major weaknesses in the early stages such that meaningful, prompt corrective actions can be initiated during the design and construction phase.

c. The " flag program," w'hich provides assurance that problems, similar to those experienced with reactor vessels holddown anchor bolts, do not exist in other similar procurement actions where in process source inspection activities are involved, was evaluated. Purchase orders and receiving documentation were reviewed by Bechtel to determine that critical design.and specification requirements were properly carried out and where questions were raised concerning product function, a " flag" was identified to the concern requiring further evaluation, discussions, and resolution by engineering and quality assurance. Evidence showed this activity to be productive and in accordance with documented instructions,
d. The 1978 and 1980 independent audit results performed by the Management Analysis Corporation on CPCo and Bechtel were evaluated

.and found in accordance with program requirements.

Overall, the personnel contacted conveyed their QA knowledge and their sincerity and dedication towards performing the activities l p\ described above. However, as a result of the findings identified

' i during this inspection, it is clear that more emphasis must be V placed on the attention to detail in the preparation and review of documents. In order to accompl'ish this, upper management must play a more active role in conveying this principle to the working staf f and observing attitudes and activities to assure QA principles and attention to detail are being properly carried out.

Unresolved Item Unresolved items disclosed during the inspection are discussed in Para-graph 3(c) and 3(d) of the report.

Exit Meeting l

The inspector met with licensee and contractor representatives at the conclusion of the inspection on December 11, 1980 and summarized the inspection scope and findings. The items of noncompliance identified during the inspection were discussed in detail. The licensee acknowl-edged the inspection results.

CP QA Program Policy No. 5 states in part, " Prior to performing... inspection on a safety related item, suppliers are required to develop written procedu.res for . . . performing required inspection and tests. These procedures reference applicable drawings, specific'ations', codes and standards. CPCo QA Departments review field... inspection procedures prior to implementation".

- Contrary to the above, the inspector determined that U. S. Testing Company ha's not established test procedures for soils work activities. The specifi .

cation for ' testing, C-208, references ASTM standards for performing specific

) tests, but does not include procedural controls or instructions for implement-ing the tests.

This is Severity Level V violation.

- establishing curient and updated distribution lists".

Contrary to the above, the inspector determined that U. S. Testing Company test result forms are not controlled. The proper documents to be used for a specific' test are not defined. There is no distribution list for the forms.

The latest revision of the forms are not controlled.

This'is a Severity Level V violatien.

3. 10 CPR 50, Appendix B, Criterion XVII, requires in part, " Sufficient reccrds shall be maintained to furnish evidence of activities affecting quality".

1. Review of Onsite Soils Works Activities ,

As a followup to NRC Inspection Report No. 50-329/80-32; No. 50-330/80-33 the region III inspectors performed an inspection of the current onsite soils work activities to verify whether adequate corrective actions have been implemented as described in Consumers Power Company response to questions 1 and 23 of 10 CFR 50.54(f) submittals. The following are the specific findings.

a. Procedural Controls for Soils Work It was determined that U. S. Testing Company' (UST) have not established written procedures for implementing the requirements of Testing Specification C-208. This specification references numerous ASTM standards for performing specific tests but does not include procedural

. control or instructions for the implementation of such tests.

(1) While observing a laboratory relative density test (ASTM 2049) if)s. it was observed that the variable theostat on the testing

\' apparatus was set at maximum setting. The lab technician stated that ASTM D2049 requires the setting of the machine at maximum amplitude. It was determined that UST did not previously determine the rheostat setting that produced the maximum density for the material being used onsite. It was assumed by UST that maximum setting produced maximum density. Relative density tests are used to assure that the inplace field density meets the specification requirements.

f l Corps of Engineers Manual EM 1110-2-1906 dated E vember 30, 1970, l Appendix XII, Page XII-8 states the following:

I "It has been determined that for a particular vibrating table, L

mold, and surcharge assecbly, the maximum dry density of a speci-l men may be obtained at a displacement amplitude (rheostat settics) less than the maximum amplitude of which the apparatus is capable; l i.e. dry density may increase with increase in rheostat setting to a setting, beyond which the dry density decreases, therefore each 1sboratory should determine for it's apparatus the r!.ecstat setth.g

! at which maximum density is produced and use this setting for sub-sequent maximum decsity testing."

I Tootnote on Page XII-S states:

l

'l n

\_/

s l'

,m. i .

? .

y "It may be desirable to redetermine the optimum rheostat setting at the inception of testing for each major project."

(

\

U. S. Testing had not determined this setting nor did a procedural

- control exist 'for the ' determination of the rheostat setting.

(2) Wile observing limited field soils work being perforned at .the metering pits south of the essential service water intake structu're at' elevation 630it was determined that samples used to perform

. relative density. tests have.been taken after.the material has been compacted. These samples should be taken prior to compaction since grain size and gradations can be. altered during compaction. The relative density test should be performed on as received caterial used prior toicompaction. . Grain. size is:ene of the important' char-acteristics of how soil behaves.- The inspector determined from a review of the available grain size analysis that there appears to be: a ' gradation change of the material comparing before and after compaction. ,

A procedural control specifying where and when to taken soil samples ,

Jshould have been established. UST.does not have procedural instruc-tions specifying the field technique where and when to take samples foi t

density tests.

(3) It was determined from discussions with the cognizant UST personnel

~

that they have been performing in place density tests "at the directiot Lj] of the onsite geotechnical engineer." However, there are no pro-cedural instructions as.to what depth below the lift being compacted Q the test should be performed. A review of the density test reports  ;

indicate that they are not correlating the density test depth to the lift being compacted.

Eased on the above, it has been determined that CPCo is in noncompliance with 10 CFR 50, Criterion V (Procedures) in that adequate laboratory and field test procedures have not been. established for the control of soil testing activities. (50-325/81-01-01; 50-330/81-01-01).

CPCo response to 50.54(f) question 23, subsection 3.11, page 23-31 states .that "U. S. Testing was required to demons't rate to cognizant ,

l

- engineering iepresentatives that testing procedures, equipment, and

- personnel used for quality verification testing were capable of pro-viding accurate test results. . ." This commitment has not been satisfied based on the above findings.

I Subsequent.to the inspection CPCo informed the RIII offices on January 16, 1981, by telephene that U. S. Testing Corporation veuld develop and issue impleentir.g recedures for soil cork activities.

These procedures will be reviewed during rubsequent inspections.

b. Document Control For Soils ork p).

I

(, It was determined that U. S. Testing was using uncontrolled forms to record quality control test results. A binder was observed in the U.S.

Testing lab which contained QC forms used to record test results. On the inside cover it stated that the index does not reflect the latest

. revision of each form. The cognizant lab personnel were not able to

. demonstrate that the latest revision of QC test for=s were being used since there were no-document control provisions established to control

- these forms. An undated U.S. Testing inter-office memo was presented to the NRC inspector as the procedure to follow when receiving revised forms. It states in part, " log into controlled forms index". The  ;

inspector requested such a form index but did not receive it. There was no documentation onsite as to what forms are to be used~for what test as well'as what are the latest revisions of the forms.

Based on the above, it was determined that CPCo is in noncompliance with 10 CFR 50, Appendix B, . Criterion VI, (Document Centrol) in that measures have.not been established to control the issuance of documents which affect quality activities. (50-329/81-01-02; 50-330/81-01-02)

Subsequent to the inspection CPCo informed the RIII office that quality contro1' verification forms would be controlled by the implementing pro-cedures. This will be verified during subsequent NRC inspections.

c. Soils Test Records

. fm

) (1) Quality assurance records for backfill work activities were reviewed

( for completeness and compliance with licensee specifications, pro-eedures, and commitments.

Bechtel field instruction FIC.1.100, Appendix A, duties and.respons-ibilities of the onsite geotechnical engineer, Paragraph 18, requires that the onsite geotechnical engineer review and initial all accept-sble UST test report forms.

ANSI N45.2.9 (Quality Assurance Records), Section 3.2.1, requires that " quality assurance records shall be considered valid only if stamped, initialed, signed, or otherwise authenticated and dated

. by auth'orized personnel".

Numerous UST density test reports were rubber stamped by the geotechnical engineer, however, none were dated. In addition no procedural controls were established for the use or control of the rubber signature stamp of the geotechnical engineer.

w Based on the above it ras determined that CPCo is in nonccrpliance with 10 CFR 50, Appendix 3, Critorien XV11 (Quality Assurance Reccrds) in that the soil test rep:rts are not ir.itialed or dated and t!4.-e vere no established controls on the use of a ruiber signature s r p.

(50-329/81-01-03; 50-320/S1-01-03) e e s

Subsequent to the inspection CPCo informed the RIII office that

[] soil test reports would be initialed and dated as required. This .

(j will be verified during subsequent inspections.

(2) Specification C-208, Section 9.1.3(d) requires the geotechnical .

engineer to review and evaluate test results when densities exceed certain values. From discussions with the previous geotechnical.  ;

engineer, it was dete,rmined that the evaluation consisted only of l a check of the numerical calculations for numerical errors. If the calculations were correct the disposition was "use as is", this.

review does not meet the requirement to evaluate test results.

Subsequent to the inspection CPCo informed the RIII office that documented evaluations of the above would be performed. This is an unresolved item pending review of the evaluation (50-329/

81-01-04; 50-330/81-01-04).

-d. Review of Nonconformance Reports The NRC inspector requested all conconformance reports regarding soil work activities since March of 1979. The f'o11owing reports were made available.

e. Qualifications of Onsite Geotechnical Engineer 7- x CPCo response to 50.54(f) question.23, subsection 3.7, page 23-20, states _

( .that, "one full time and one part time onsite geotechnical soils engineer have been assigned." The inspector requested the qualifications of the onsite geotechnical engineer. A resume was presented to the inspector as representing the assigned individual to implement the conmitment in order to preclude future soils problems. This engineer is to provide the technical direction and monitoring of the entire earthwork process.

The resume that was presented was of an " Engineering Technician" with no previous formal education in engineering or geotechnical engineering.

-The engineering technician.had nominally 15 years of field and laboratory testing of soils.

This information was discussed with representatives of the KRC geotech-nical branch. It was determined that CPCo committed to provide techn-

~ ical-direction from a geotechnical engineer capable of being recognized and licensed by a state board of registration of professional engineering or equivalent.

In view of the fact that adequate technical direction had not been pro-vided per the commitment by CPCo in the 50.54(f) response it has been determined that CPCO is in deviation from a NRC commitment as described

. 'in Appendix B of the transmittal letter of this report. (50-329/81-01-05; 50-330/81-01-05)

/

Subsequent to the inspection, CPCo informed the RIII office that a (x~' geotechnical engineer would be ensite beginning January 19, 1981 and that job descriptions and qualifications for the geotechnical engineer for the speciality remedial work to follow would be developed. This

action will be verified during subsequent inspection.

l 2. Eorated Vater Storage Tank Reanalysis .

H During the inspection, the licensee informed the inspector that the prelimin-ary structural reanalysis of the borated water storage tank ring foundation yielded-results that indicated the foundation to be overstressed. The in-spector inquired to the quality assurance group if this condition had been

. considered for reportability. Af ter this inquiry, the Manager of Quality Assurance produced the CPCo form entitled, " Safety concern and reportability evaluation" for the IWST ring foundation.

' This d cument indicates. that a. finite element analysis results in' forces ind. :. :ents in excess of TSAR allowables. The reportability evaluation indiceted the' event was "not reportable" with further evaluation necessary.

T'.e p2anned actions included retaining a c:nsulttnt to review the results

lisined by.the' analysis and/or perf:rm an independent check and excavate
.3 i :;c:t the f:undati:n for si;ns of : .'e rs trerring (i.e. , cracking).

,s On January 23, 19S1, CEPo infor ed the RIII office.the excavation around the.

( Unit I tank was complete and that cracks were observed in the areas of over-

\s,-} , stress. CPCo identified this item as a 50.55(e), significant construction deficiency. This item is under review by the KRC staff.

The inspector informed the Region III office and NRR project canager on Janua ry 9,1981. The licensce's evaluations of the matter are included as Attachment No. 1 of this report.

Unresolved Items Unresolved items are matters about which more information is required in order to ascertain whether they are acceptable items or items of noncompliance or deviations.

Unresolved items disclosed during this inspection are discussed in Section II, Paragraph 1.c.(2).

Exit Meeting The inspectors met with licensee and contractor representatives at the conclusion of the inspection on January 9,1981 and summarized the inspection scope and findings. The licensee acknowledged the inspection findings. Subsequent to the exit meeting the inspectors and RIII management telephoned on January 14, 1981 the Quality Assurance Manager in order to verify what corrective action would

.be taken based on the inspection findings. On January 16, 1981, CPCo' informed i the RIII office of the actions te be taken which are contained in the report l , s Section II, Paragraph la, Ib, Ic, and le.
