Intr 6 cion This report is one of several reports docus..iting results of inspections performed at the Marble Hill construction site over the past several months by the NRC Office of Inspection ar.d Enforcement (IE) Region III and by the U. S. /.rmy Engineer Waterways Experiment Station culminating in the issuance of an Order Confirming Suspension of Construction on August 15, 1979.
On June 12, 1979, the NRC received information that a former worker at the Marble Hill site had alleged improper repairs of honeycomb areas in concrete. The allegations were contained in a sworn statement submitted to the Office of Nuclear Reactor Regulation (NRR) through an attorney representing an Indiana intervenor group.
Subsequently Region III IE received a copy and initiated an investigation on June 22, 1979. The results of this investigation are documented in Report No. 50-546/79-08.
Prior to receipt of the allegations during inspections conducted in April 3-6 and April 30-May 3, 1979, problems were identified relative to the placement and epair of concrete. A management meeting with PSI was held on May 15, 1919, to discuss these findings. The results of the inspections and the May 15, 1979, meeting are documented in Report hos.
50-546/79-03, 79-04 and 79-05.
On June 26, 1979, a second meeting was held with PSI officials to discuss the findings of the investigation at that point and the fact that deficient repairs of concrete had been identified. As a result of this meeting PSI agreed N stop concrete activities for safety related structures, perform non-destcuctive examinations of various concrete structures, identify and evaluate repaired areas for adequacy and review their entire program for concrete activities on site. An Immediate Action Letter (IAL) dated June 27, 1979, was issued confirming this agreement. A copy of this letter is attached to Report No. 50-546/79-07.
On June 27-29 and July 2-7, 1979, an inspection was conducted relative to items 1, 2, 3, 4 and 5 of the IAL. Based on the results of this inspection, documented in Report No. 50-546/79-07, IE: Region III concurred in the resumption of concrete placement for Safety Related Structures. The conditions for this concurrence are contained in a Region III letter to PSI dated July 13, 1979. A copy of the July 13 letter is attached to Report No. 50-546/79-07.
Report No. 50-546/79-09 documents results of an inspection conducted during the period July 9 through July 27, 1979.
Initial results of this inspection led to a site managemnt meeting on July 20, 1979, and an understanding that PSI would again stop concrete activities for Safety Related structures. A second IAL dated July 23, 1979, was issued documenting this understanding and a copy is attached to Report No. 50-546/7 -09.
Report No. 50-546/79-10 documents the results of an inspection conducted July 10-13, 1979, relative to the erection of safety related steel structures.

On July 24, 1979, IE: Region III learned that a team from the National Board of Boiler and Pressure Vessel Inspectors had conducted an inspection on June 12-14, 1979, at the Marble 6111 site during which numerous items of noncompliance with the ASME Code were f e d.
As a result of the National Board's inspection and the IE: Region III findings a comprehen-sive team inspection was conducted during the period July 26-28 and July 31-August 3, 1979. The purpose of this inspection was to identify the underlying causes leading to the concrete and ASME code deficienc~ies and to determine if they were symptomatic of problems in other areas.
The results of this inspection, documented in Report No. 50-546/79-11, indicated tha' problems in the Quality Assurance / Quality Control (QA/QC)
program in coucrete construction activities extended to other construction areas as well.
At the request of PSI, representatives of Region III and PSI management met again on August 1, 1979, to discuss PSI's planned actions to correct the programmatic QA/QC problems at the Marble Hill site. The meeting included a discussion of the desirability of stopping all safety related construction activities at the Marble Hill site until such time as the licensee demosstrates that it has an effective QA program acceptable to the NRC. The licensee issued a stop work order on August 7, 1979, for all safety related cons +.ruction.
An order confirming this suspension of construction was issued en August 15, 1979, by the NRC. A Meeting was held with PSI management in the Region III offices on August 15, 1979, to discuss the conditions of the con; ming order. The meeting is documented in Report No. 50-546/79-14.
On June 28, 1979, NRC headquarters personnel met with Congressman Deckard of Indiana. During this meeting Congressman Deckard provided information concerning allegations he had received involving improper activities by the concrete testing laboratory at the Marble Hill construction site. As a result of this information the U. S. Army Engineer Waterways Experiment Station was requested to perform an independent inspection of the testing laboratory activities. The results of the Corps of Engineers inspection conducted July 25-27, 1979, are documented in Report No. 50-546/79-16.
Report No. 50-546/79-18 documents the results of NRC Region III followup inspection conducted August 13 and 14 and September 4-7, 1979, relative to the unresolved items identified by the Corps of Engineers in report No. 5?-546/79-16.
Report Nos. 50-546/79-06, 12, 13, 15 and 17 document results of routine or surveillance inspections conducted May 29-June 1, August 7-10, August 3-17, August 21-24 and August 27-31, 1979, respectively.

INSPECTION ITEMS A.
Procedure Review This is a general requirement to review all laboratory and field testing procedures to assure appropriate quality control measures have been incorporated for the testing of concre_te, concrete materials and reinforcing steel. The specific details of review are contained in the following sections.
B.
Materials (1) Cement. All cement is sampled at the project site by the UST Batch Plant Inspector,at a prescribed frequency of one sample per 1200
tons.
The sample is identified and sent to the UST laboratory in Hoboken, New Jersey, for testing. A Log of all cement shipments is kept
,
by the Batch Plant Inspector. The Log includes date, ticket number, weight, accumulative weight in pounds, and. accumulative weight in tons.
A portion of the cement log was examined by the WES inspectors.
A re-view of 31 test reports from the Hoboken Laboratory covering the period from 21 December 1977 to 5 July 1979 indicated only one instance of a failure of a sample of cement to comply alth the requirements of the specification. Cement sample No. 2 taken on 6 March 1978 exceeded the total alkalies permitted by the specification.
It contained 0.70 percent total alkalies, whereas ASTM-C 150-73a permits a maximum of 0.60 percent The test report did not indicate what action beyond notification was taken by PSI. 'WES understands that the NRC plans further review of this item (546/79-16-01; 547/79-16-01).
One period of missed sampling frequencies of cement did occur in August and September 1978 and is described in Section I(10).
(2) Fly Ash.
All fly ash is sampled at the project site by the UST Baten Plant Inspector at a prescribed frequency of one sample per 200 tons. The sample is identified and sent to the UST laboratory in Hoboken,
-
New Jersey, for testing. A Log of all fly ash shipments received is kept I
by the Batch Plant Inspector. The Log includes date, ticket number,
.
truck number, trailer number, weight in pounds, accumulative weight in pounds, and the fly ash sample number.
A portion of the Fly Ash Log was 1 2 1 J

.
examined by the WES inspectors. A review of 41 test reports from the Hoboken Laboratory covering the period from 19 December 1977 to 29 June 1979 indicated three instances of fly ash test failures. All three concerned the fineness of the fly ash and occurred in consecutive samples in May and June of 1978. The three fly ash test reports gave no indication of what action was taken to disposition the nonconforming fly ash. WES understands that the NRC plans further review of this item (546/79-16-02; 547/79-16-02).
One period of missed sampling frequencies of fly ash did occur in August and September 1978 and is described in Section 1(10).
(3) Aggregates (fine and coarse).
It was impossible to check all
-
the grading test records for the job because of the large number of tests run.
Job requirements call for a daily check of grading of both fine and coarse aggregate and a grading for each incoming shipment. As a spot check, the month of June 1979 was examined.
A total of 25 deter-minations each for grading of both fine and coarse aggregate
're made.
All were satisfactory except for Daily Coarse Aggregate Sample No. 292-158 which on 7 June 1979 did not meet the percent passing requirement on the 1/2-in. size. The report of the results indicates that PSI was notified of the failure on 8 June 1979 but gives no other informa*. ion concerning dicposition of the nonconforming material. WES understands that the NRC plans further review of this item (546/79-16-03; 547/79-16-03). Moisture content is required by Specification Y-2850 to be determined twice daily; unit weight, weekly; and s; ecific gravity and absorption, monthly, during concrete production.. UST personnel stated that they met these frequencies.
UST has no responsibility for the maintenance of aggregate stockpiles.
(4) Water. All water analysis is performed at the UST laboratory in Hoboken, New Jersay.
Fe. a review of the water testing, see Section 1(1).
(5) Reinforcing S eel.
Reinforcing steel is identified for testing by N-MH personnel.
This identification is carried over onto UST records when the samples are tested.
The job specifications require testing of at least one tension specimen from each bar size for tsch 50 tons or fraction thera:i of the reinforcing i21? ^'7

D.
Qualification of Lab Personnel for the evaluation of laboratory technicians with re-See Appendix ga;i to the manner in which testing is conducted.
E.
Observe Field Testing No concreting operations were accomplished during the WES inspection at Marble Hill.
F.
Concrete Mix Design Qualifications The basic mixtures that were given to WES were found to be propor-tioned according to ACI 211-74, Recommended Practice for Selecting Pro-portions for Normal and Heavyweight Concrete. This includes aggregates, admixturca, cement, batch quantitles, air content, and yield. The water-cement ratios for the 3500 and 5500 psi mix designs (air entrained) were generally higher than specified by ACI 211. However, a review of com-pressive test results indicated that adequate compressive strength was being obtained.
G.
Review of Concrete Strength Results Upon the completion of the testing of concrete cylinders for compres-sive strength, personnel from UST transpose the information from labora-tory and field concrete reports to Sargent and Lundy computer forus SC-1 One copy of the UST Concrete Reports and SC-1 and SC-2 are and SC-2.
then sent to Sargent and Lundy via PSI mail service. Sargent and Lundy then performs all statistical analysis of the data through the use of conputer programs.
Sargent and Lundy Specification Y-2722, page 4-5, Section 409.2,
" Mix Design," requires three different concrete strengths:
a
"c3.1 2000 psi at 28 days, c3.2 3500 psi at 91 days and c3.3 5500 psi at 91 days" f2f
'$
,
.
In discussion with Mr. Arthur Weiss, Concrete Technologist for Sargent and Lundy, he noted that the 2000-psi strength requirement was for " mud mats" and was inserted in the specification only as a point of reference, as strength was not critical for these elements.
Sargent and Lundy used the quality control procedures described in ACI 214-65, Recommended Practice for Evaluation of Compression Test Re-sults of Field Concrete, 1965.
A 1977 updated version of this document is now available; however, it incorporates all the features of the 1965 was used by Sargent and Lundy.
The data from the 3500-version whi25 and 5500-psi concrete test cylinders appear in computer printout reports entitled Statistic =t Analysis and Evaluation of Field Concrete by Com-
.
puter Program for Public Service Indiana Marble Hill-Units 1 and 2. Proj-ect No. 4808-15. These printouts also include all statistical data and computerized control charts for the data.
Eleven of these reports numbered MHCON-1 to MCHCON-11 covering a time period of 6 July 1978 to 9 May 1979 were reviewed.
Section 413.9 of S&L Specification Y-2722 includes the criteria for evaluation and acceptance of concrete compression test results.
A review of the MHCON report series indicates that the concrete strengths exceed the strength criteria of the job. The average etrength of all of the 492 test samples (two cylinders per sample) of the 3500-psi mixture evaluated at 21 days exceeded the specified strength for the job with an overall average on the job of 6020 psi.
The average strength of 415 of the 418 test samples (two cylinders per sample) of the 5500-psi mix-ture evaluated at 91 days exceeded the specified strength for the job with an overall average on the job of 7006 psi. All of the samples falling below the specified strength were statistically acceptable.
The individual test reports for the 2000-psi mixtures over the period 28 February 1978 to 11 May 1979 were reviewed and none of the 196 test cylinders tested had strengths less than the specified strength.
A spot check on the statistical calculations on the MHCON report
series indicated that they were properly done.
The MHCON reports indicate that the proper number of; cylinders were being tested at 91-days age.

H.
Jon-Conformance or Deviation Reports Two types of non-conformance or deviation reports were made available for inspection. These were UST Internal Corrective Action Requests (ICAR)
and PSI Field Corrective Action Requests (FCAR).
(1) Internal Corrective Action Request (ICAR). PQAM-1036, Rev 1, pages 17.1 and 17.2, paragraph 17.0, Corrective Action, requires that
"17.2 In the case of significant conditions adverse to quality, the cause of the condition shall be determined and correct'.ve action taken to preclude repetition.
All actions in the '.dentifi-cation, cause, and correction of these conditions shall be documented, resolved, and reported as specified in.the 7.nternal Corrective Action procedure (UST-CA-1).
17.2.1
"Significant" is defined as having direct impact
'
on the acceptability of materials tested or items ir.spected."
It also requires that
"17.3 The PSI QA Construction Supervisor shall be advised of significant conditions adverse o quality by issuing him in-formation copies of Internal Corrective Action Requests."
Th. procedure that is folleved i.s that whenever any US Testing staff member detects a deficiency on work performed by or for UST, they report this deficiency by initiating an ICAR Form No. USTF-CA-1.1.
The Site Project Supervisor reviews the ICAR and determines if it is valid.
If the ICAR is determined not to be valid, the Site Project Supervisor attaches his reasons for that decision to the original docu-ment, and submits it to his next higher level of management in the UST Hoboken office for concurrence.
Where a deficiency is considered valid, the Site Project Supervisor determines the corrective action necessary to correct the specific deficiency cited and to prevent recurrence. He also determines if the corrective action due date is appropriate.
He then forwards a copy cf the ICAR to the next highest level of management in the UST Hoboken
'
office.
The Site Project Supervisor is required to close out c11 ICAR's and sign off on them when he does.
PSI maintains a log of all ICAR's.
Forty-seven ICAR's were received by PSI. The first recorded entry was in October 1977,

The ICAR's are very brief and to the point.
For purposes of expe-diency they can be grouped into the following eight categories:

Calibration Pocket thermometer out of calibration.
Test Frequency Missed frequency tests on concrete.
Test Omission Grout cubes not made.

specification
The " Typical Example" above is by title entered into the ICAR log.
Other related ICAR's have different titles and may not be related to the example shown in any way with regard to content.
None of the ICAR's appeared to be out of the ordinary from what might be expected on the startup of any large multi-year construction project.
The fact that UST was required not only to correct the problem but to insure that it did not become a repetitive problem was reficcted in the absence of any identical, recurring problem or theme in the ICAR's already submitted.
(2) Field Corrective Action Request (FCAR). PSI personnel, when they become aware of any problems associated with the duties, responsi-bilities, or performance of USL will give oral notification of the problem to UST and attempt to resolve the matter.. Depending on the severity or frequency or b'oth of the problem an FCAR may also be issued.
The FCAR is a. written request to correct the problem. These FCAR's are recorded in the Field Corrective Action Request Status Log. The first was issued to UST in April 1977. A total of twenty-eight (28) FCAR's J have been issued through July 1979.
PSI personnel advised WES.that problem areas are identified by the PGI inspectors through surveillance inspections of UST.

reports test report.
The " Typical Example" above is by title entered into the Field Corrective Action Request Status Log.
Other related FCAR's have different titles and may not be directly related to the example shown.
Nine of the eleven FCAR's related to improper test reports occurring between 29 November 1978 and 13 February 1979.
UST hired a document control clerk to resolve.the reporting problems and no fttrther FCAR's have been issued in that area. As in the case of the ICAR's, the problem areas do not appear to be out of the ordinary and al?. were re-solved to the satisfaction of PSI.
I.
Specific Allegations The specific allegations were an enclosure to a memorandum dated 5 July 1979 from Mr. H. D. Thornburg, Director, Division of Reactor Con-struction Inspection, NRC, to Mr. J. G. Keppler, Director, Region III, NRC, subject, Metting With Congressman Deckard and were transmitted to Mr. Hoff, WES, on the morning of 25 July 1979 by an NRC representative at Marble Hill. Attempts to look into these allegations are reported in the following paragraphs.

Finding:
Sargent and Lundy Specification Y-2722: Amd 3, dated 29 March 1979, pages 4-14a and 4.15, paragraph 508, WATER, requires the following:
"408.1 Mixing water and ice shall conform to the requirements specified in CC-2223 of ASME Boiler and Pressure Vessel Code, Section Ill, Division 2, except that total solids content and limits on chloride ions indicated in CC-2223.1 shall not apply.
Maximum content of chloride ions in the mixing water shall not exceed 500 ppm.
408.2 Testing:
Initial Testing: Initial tests-preliminary to mix design, a.
will be performed by' Purchaser to insure compliance with the requirements specified in Parag.aph 408.1.
b.
Control Testing: The following tests, as specified in Specification Y-2850, will be performed by an independent testing laboratory to ascertain conformance, with the requirements specified in Paragraph 408.1:

All,f the data included in the test reports noted above indicated that all of the water and ice tested from all sources met the require-
.
ments of the job. The UST limits specified on water for chemical analysis test reports differ from those specified by S&L specification Y-2722.
The UST test reports specify 250 ppm (max) for chlorides, whereas S&L Specification Y-2722 allows 500 ppm.
All samples meet the lower limit.
The total solids content requirement is deleted in S&L Specification Y-2722 but appears on some test reports as 2000 ppm, maximum.
All samples also met this limit. Both ice and yater samples were evaluated at 6-month intervels from the time of their initial testing. This also conforms to the job requirements.
If a problem existed with the water supply, it is not apparent from the test reports.
'
(2) Allegation No. 2
"Apparently US Testing used temporary facilities at some time for concrete testing. A trailer may have been used and humidity and temperature control may not have been properly controlled."
Findings UST did operate out of both an old house and a mobile trailer
.
through July 1978.
Field Corrective Action Request's (FCAR's) issued by PSI in November and December 1977 indicate that problems of temperature and humidity control did exist at that time and were corrected.

(5) Allegation No. 5
"A point was made that US Testing was never made aware of where concrete cylinders had been taken from.
Traceability of concrete samples should be checked and it should be ascertained if all samples were tested according to the proper procedures."
Finding:
PQAM-1036, Revision 1, page 9.1, paragraph 9.1 states that:
" Test samples taken by United States Testing personnel shall be adequately identified at the time of sample selection to as-sure traceability to the material f rom whic'h they were taken.
This identification shall be maintained and transferred as re-quired during the handling, storage, and testing of the samples to assure that this traceability is retained. When samples are removed from their marked containers, o.r markings are destroyed during the testing cycle, the identification shall be transferred to records."
Also in QCP-3, Rev 1, page 2, Quality Control Procedures for Sampling /
Testing Concrete,Section III, Responsibilities, paragraph 4.0, Field Technician Level I, it states:
"4.1 Sample, log, test, and prepare concrete, bash (backfill material consisting of cement, fly ash, stone,.and water), and grouts specimens fr - the fresh concrete and grout as outlined in this procedure."
These technicians are furnished by UST.
The UST Site Project Supervisor stated that all concrete cylinders are made by UST personnel at. the point of placement as described in S&L Y-2722. The cylinders are consecutively numbered from the first day These numbers correspond to batch ticket numbers which of placement.

.
During this inspection, WES observed no instances of lost concrete cylinder identification markings.
With regard to the use of proper procedures for the testing of con-crete cylinders, one instance of improper loading rate during compressive strength testing was noted.
See the section of this report on laboratory inspection (ASTM C 39) for further details. WES understands that the NRC plans further review of this item (545/79-16-04; 547/79-16-04).
(6) Allegation No. 6
" Reportedly PSI '. d been made aware of concreting prob-lems in writing and had ignored the notification."
Findings:
The UST Site Project Supervisor stated that when his organization became aware of a concreting problem either through testing or obse.rvation, PSI was informed.
There was no follow-up by UST on any of their notifi-cations as it is not their responsibility nor did they have the authority to take any action on matters of that sort. A PSI representative stated that PSI looks into all notifications of concrete problems and takes corrective action when warranted. UES addressed only the UST notification of PSI concerning concreting problems.
WES understands that the NRC

(7) Allegation No. 7
"Apparently PSI inspectors were supposed to witness all pours completely and they have not."
Findings:
The NRC representative instructed WES not to address this specific allegation as it does not apply to the UST program, but WES understands that the NRC plans further review of this item (546/79-16-16; 547/79-16-16).
(8) Allegation No. 8
" PSI and/or US Testing inspectors may not have been familiar with the PSI Q/A manual."
,
This is a subjective matter as the degree of familiarity depends on the need-to-know and this varies with the level of the inspector.
The UST Site Project Supervisor stated that all his inspectors are adequately familiar with the manual.
The PSI QA Manual is kept in both the UST control office and. laboratory where it is available to all in-spectors.
Specific questions involving the Q/A manual were asked of a PSI QC During this interview, he exhibited sufficient knowledge of inspector.

Finding:
Sargent and Lundy 2pecification Y-2722, Amd. 3, dated 29 March 1979, page 4-24, paragraph 413.6, Control Tests, states:
"a.
Control testing will be performed by an Independent Testing Laboratory in accordance with Specification Y-2850.

Table 4-1-5 of Y-2722 and Table 4.2 of Y-2850 contain the same informa-tion with regard to the amount and frequency of test cylinders to be made.
The exact placement alleged to be improperly sampled could not be established.
(10) Allegation No. 10
.
"Apparently tSere is some irregularity with the Fly Ash Log."
Finding:
.
Sargent & Lundy Specification Y-2722, Amd. 3, dated 29 March 1979, page 4-10, paragraph 404.1.b states:
" Control Testing:
Control testing will be performed by an independent testing laboratory in accordance with Specification Y-2850, to ascertain conformance with ASTM C 618 for the following ASTM test, based on a frequency of every 200 tons."
'
The Fly Ash Log is n continual record of fly ash received on the job.
The original is kept by the Batch Plant Inspector for UST.
The UST office has a copy. With each 200 tons of fly ash received, a sample is to be taken and sent to the UST laboratory in Hoboken, New Jersey.
Between 29 August 1978 and 29 September 1978, four control test frequencies were missed on incoming fly ash.
This is reported on ICAR No. 1036-25.0.
As a result of this ICAR, a new batch plant inspector was assigned.
A Fly Ash Log was also incorporated into PQAM-1036 Supplemental Procedure QCP-1, Batch Plant Inspection.
Included in UST files is a ccpy of a letter to the former batch plant plant inspector dated 17 November 1978 which terminates his employment.
The letter notes that the inspector was in possession of two controlled documents, the cement log and fly ash log, and that he would not return them. This refusal plus his neglect in sampling were cited as the reasons for his dismissal.
Also included in the files is a copy of a letter dated 28 November 1978
.
from AMAX Resource Recovery Systems, Inc., the fly ash supplier.
The 121'

.
.
letter acknowledges shipment to UST (Hoboken, New Jersey) of a portion of the samples taken by AMAX at the mill.
These samples represented the four fly ash shipments made to N-MH but not sampled during the period noted above.
UST test reports for these belated samples indicate that all were satisfactory and the S&L letter of 25 July 1979 satisfactorily -dispositioned the fly ash material based on these test results.
Also included in the above mentioned ICAR were four control test fre-quencies that were missed on int.oming shipments o.f cement.
These missed frequencies occurred between 1 August 1978 and 22 September 1978.
The S&L Ictter dated 25 July 1979 satisfactorily dispositioned the use of the cement based on a review of the original Certified Material Test Reports (CMTR)
-
and associated concrete compressive strength test results.
(11) Allegation No. 11
"Apparently aggregate has been improperly stored:
sand was not kept damp and shape of aggregate piles indicated segregation of ag-gcegate."
Findings:
Sargent and Lundy Specification Y-2722, Amd. 1, 21 August 1978, page 4-38, paragraph 425.3, St'oring and Handling Material, states:
"a.
Adequate precautions shall be taken in storing and handling concrete material to prevent (1) segregation of aggregates, (2) intermixing of the separate' sizes of aggregate prior to batching, (3) contamination of material by dirt or other foreign substances, (4) damage to cemen*_ by dampness or weather, (5) reteation of free surf ace water in the aggre-gates, and (6) excessive chipping and breaking of coarse aggregate which might produce undersize cccumulations. At the time of batching, all aggregate shall be dried or drainec' to obtain a stable moisture content that is not less than saturate 3 surface dry nor shall the moisture con-tent of fine aggregate exceed saturated surface-dry condi-tion by more than 8 percent. Ground storage of concrete aggregates will be allowed."
-
The responsibility for constructing and maintaining the aggregate storage piles belongs to N-MH.
7.t is difficult to ascertain at this point in time whether previous stockpiles were improperly constructed,
-
thus producing segregation. The daily grading tests may be able to pick up problems in segregation if separate samples taken from various 121J 20]
_.
.
,
.
locations in the stockpile each had a grading determined for it.
Present methods of sampling, while acceptable, do not pick up variations through-out the pile because only one test is run. A review of grading test re-sults revealed no recurring grading failures.
Regarding the moisture content of the sand stockpiles, WES experience has shown that in general it is very difficult for any part of a sand stockpile other than the exposed surface to dry out if the pile is sub-jected to occasional rains such as occur in areas such as F arble Hill.
(12) Allegation No. 12
"There may have been a problem with the correction factor for
aggregate size in arriving at the proper air entrainment value."
Findings:
Sargent and Lundy Specification Y-2722, Amd. 1, 21 August 1978, page 4-5, paragraph c2.2, sectes:
" Air content shall be measured by ' Test for Air Content of Freshly Mixed Concrete by the Pressure Method' (ASTM C 231)."
ASTM C 231-73,. paragraph 4, Determination of Aggregate Correction Factor, contains a co= ment which states:
" Note 5 - The aggregate correction factor will vary with different aggregates.
It can be determined only by test, since apparently it is not directly related to the absorption of the particles. The test can be easily made and rust not be ignored.
Ordinarily the factor will remain reasonably constant for given aggregates, but an occasional check test is recommended."
For the work done to date, UST personnel stated that the aggregate
.
correction factor has not varied.
If the aggregate size, type, and source has remained constant, the correction factor, according to ASTM C 231, should not be changing.
If a problem did exist for the correction f actor, WES was unable to define it with the information given in the allegation.

Finding:
Sargent and Lundy Specification Y-2722, Amd. 3, 29 March 1979, page 4.15, paragraph 409.lal, states:
" Reinforcing bars for all Category I structures shall be Grade 60 deformed bars meeting the requirements of ASTM A 6.15.72 with the following modification.
Paragraphs 4.2, 7.3, 8.3, and all of Sections 9 and 10 as indicated below shall be used in lieu of the same parts as specified in A 615-72; (Annual Book of ASTM Standards, Part 4, April 1974)."
PQAM-1036, QCP-11, Rev. 1, Div. II, page 17-18, paragraphs 3.0 and 4.0,
~
further details the requirements.
As of 25' June 1979, a total of 1357 bars were tested. A random sampling of ten (10) test reports over the period of 4 August 1978 to 25 July 1979 was made. These reports included the results of 93 bar tests of which 21 failed. UST personnel stated that 309 of the 1357 total rebar tests were failures.
In the reports examined, the principal failures were in yield strength and bending, being divided about equally.
When failures occur, PSI is notified to assure proper follow-up in ac-cordance with Specification Y-2722.
(14) Allegation No. 14
"Apparently there have been a large number of nonconformances reported in connection with Category 1 columns."
Findings Only one nonconforming report could be located that specifically addressed a Category I concrete placement. This was documented as ICAR No. 1036-32, dated 19 December 1978, subject: Omission of unit weight test for a category one pour #2TW-356-2. According to the ICAR on 15 December 1975, pour number 2TW-356-2 was placed as a Category I pour, however, no unit weight was run.
That was the only pour of the day that was using 3504 " mix design." The written placement notification information received by UST from N-MH listed 2TW-356-2 as a Category II
-
pour.
UST treated the placement as a Category II placement and did not
-
make the unit weight check normally associated with Category I placements.
~
Actions were taken to prevent this type of communication problem from occurring again.

WES addressed only UST nonconformances (ICAR). WES understands that the NRC plans further review of thin item (546/79-16-17; 546/79-16-17).
(15) Allegation No. 15
"Apparently there has been some problem with cement / water ratio in Class I concrete."
Findings:
Sargent and Lundy Specification Y-2722, Amd. 1, 21 August 1978, page 4.7, paragraph 402.2, Mix Design, statar:
"e4.
Field control shall be based on adju'
ent of the water-cement ratio to maintain the required compressive strength average, maintenance of slump and air content, and adjustment to
temperature of plastic concrete."
Futhermore in paragraph 413.1, page 4-20b:
"...If additioral slump is required, cement and water may be added provided the taximum allowsble water / cement ratio is not exceeded..."
And finally, on page 4-25, in paragraph 413.7, it is noted that:
" Addition of Water to Mixture: Water may be added to bring slump within specified limits only if all the following require-ments are met:
Maximum amount of water to be added, as determined by a.
the water-cenent ratio of the design mixture, is established by operating personnel of the central mixing plant.
b.
...
d...
.
e.

The allegation is not well defined and it is difficult to pinpoint the exact problem. The above specifications are stated to show that a lot of flexibility is allowed in the specification for the adjustment of water in the mixture. These adjustments change the water-cement ratio.
