~
l Jackson, MI 49201 Gentlemen:
By letter dated January 10, 1983, Consumers Power Company described its proposed Construction Completion Program (CCP) for the Midland nuclear facility. This submittal was followed by a public meeting in Midland on Tebruary 8,1983 for the NRC to obtain a better understanding of your As a result of proposed program and to obtain public input on the CCP.
our review of the CCP to date, we find we need the following additional information.
A.
Please provide a more detailed description of the scope of the CCP and how it is scing to function. Your discussions should address the following subjects er concerns:
1.
Because of problems identified by the NRC during the special, inspection of the diesel generator building and because similar problems were found in other areas of the plant during subsequent inspections by CPCo, we believe that 100% reinspection of access-ible safety related structures, systems, and components is war-raatad. Should you intend doing less than 100% reinspection, please provide the details of your proposed program and the technical rationale for accepting a sampling approach.
2.
A description of the reinspection program for accessible systems and components important to safety.
3.
A description of the measures you intend to institute to assure that QC reinspection will be sufficiently independent of team controls.

cently taken to address the adequacy of the review of PQCI's prior to training being initiated on the PQCI's. In additica, describe the steps you have taken to ensure that all questions raised during PQCI training sessions will be resolved prior to certification to affected PQCI's.
5.
As a. result of the diesel generator building inspection, hold i
points were established by.the NRC for the purpose of determin-ing that you adequately performed all of the actions to which you have committed before allowing the work to proceed beyond the hold point. In view of the total CCP offert, the NRC does not wish to rerein in the approval chain; therefore, you are requested to develop measures that will ensure that key hold points are honored and that critical paramet.crs, of your program are in place before proceeding to the next step.
6.
A description of the controls you will use to ensure all problems have been identified during reinspection of a system or area prior to start of repair work or new work on that system or*in that area.
7.
A description of the controls you will use to ensure that no new work will be performed that would'cause a known nonconformance to be inaccessible.

The CCP overview should continue until CPCo and the NRC have con-fidence in the adequacy of the CPCo quality assurance program.
C.
Please propose a candidate organization that Consumers Power Company considers acceptable for the installation implementation overview together with your rationale for selecting that organization.
- he NRC will also need the following:
1.
Sworn statements from the candidate corporation and all personnel who will he involved in the, third party installation implementa-tion overview, addressing the independence factors described in Chairman Palladino's letter of February 1, 1982 to Congressman Ottinger and Dingell.
2.
The resumes of the key personnel to be involved in the third party 4 :.
overview.
3.
A description of the experience of the candidate corporation that qualifies the corporation to perform an independent third party overview.
l' The NRC will determine the acceptability of the candidate corporation and will notify CPCo. Our present view is that the installation implementation overviewer would not be acceptable to also perform the independent design and construction verification program.

SUBbECT:
DECEMBER 7,1982 MEETING ON MIDLAND QA IMPLEMENTATION i
The purpose of this memo is to document my understanding of the conclusions reached at the meeting held in Bethesda on December 7,1982 among Region III, Division of Licensing and Inspection and Enforcement (HQ).
The purpose of the meeting was to discuss (a) Midland's QA implementation history, (b) the recent P.egion III inspection of the Midland Diesel Generator Building, (c) the recent decision by Consumers Power to stop certain safety-related i
work being performed by Bechtel, and,(d) discuss the staff's position and approach regarding the QA implementation programs (including IDVP) which have been proposed'by Consumers Pcwer'over the past three months.
BACKGROUND By letter dated September 16, 1982, the staff (Region III W/NRR concurrence) approved two " quality assurance plans" for the Midland Plant.
Those plans were MPCP-1, Revision 3 (for the overall Midland work scope) and MPQP-2, Revision 0 (for the soils remedial work only).
Since that time, the following submittals have been received from Consumers Power Company:
1.
September 17, 1982 - CPCo letter #18845 proposing a QA " implementation plan" for the soils remedial work QA plan. This proposal followed a September 2 meeting in Chicago between CPCo, RIII and NRR and contained the following elements:
a) A third-party assessment (by Stone and Webster) of the auxiliary building underpinning impleme'ntation.
b)
Integrating all QA/QC functions into one organization under t
the control of Consumers Power.
^
c) Creating a " soils project organization" with single-point accountability and dedicated employees.
d) Upgrar.ing training of workers and supervisors involved in the soils remedial work.

f) Increasing senior management involvement in the soils work.
g) Developing an administrative system for tracking design
[
'comitments.
2.
September 17, 1982 - CPCo letter #18850 proposing QA " implementation plan "for.the total Midland work scope (vs soils only).
This plan documented two significant new commitments by CPCo with details of the second commitment (IDVP) to be supplied at.a later date.
Those commitments were:
a) Placing all QA/QC functions under the direct control of Consumers Power (such as was done for the soils remedial work)s This entailed. requalifying Bechtel QA/QC personnel t'o Consumers Power procedures.
b) Initiating a " total project independent verification program" consisting of a " horizontal" type review using INP0 quidelines and a " vertical slice" evaluation of a critical plant' system.
At the time of this letter, contractors had not been selected to carry out these programs.
3.
October 5,1982 - CPCo letter #18879 which supplied details regarding the independent review program committed to in letter #18850.
This letter proposed a 3-part program consisting of:
a). Biennial QA audit by MAC b)
INP0 type review by MAC c)
Independent Design Review of the AFW system by Tera Corporation.
4.
December 3,1982 - CPCo letter #19750 modifying the program proposed in the October 5 letter as the result of two meetings (10/25 and 11/5) with (and verbal feedback from) the staff.
The modifications and additional commitments were:
a) To not have MAC coordinate the results of Tera's indepencent review as originally proposed.
b) To maintain the MAC and Tera evaluations completely separate in terms of personnel involved.
c) A second system will be included in the Tera IOV.
The staff was given three candidate systems to choose from on the basis of the PRA.
Those systems are the electric power system (diesel generator), the safeguards chilled water system, and the containment isolation system.
d) To expand the Tera IDV to include more in-depth review of construction activities.
e) To ensure any discussion between Tera and CPCo personnel regarding confirmed findings would take place in open meetings of which the NRC would be notified.
f) The INP0 evaluation final report would be sent to the NRC at the same time it is sent to INP0.

SUMMARY
OF MEETING
~
After detailed discussion of the topics on the meeting agenda, it-is my
+
understanding that the following general agreements were made:
1.
Region III intends to document the results of the DGB inspection in a formal report to be issued mid-to-late December,1982.
2.
On the basis of the December 6 CPCo letter, Region III would issue a letter in the near future to authorize the start of work on pier 12.
3.
Region III would prepare a letter to Consumers Power (w/NRR concurrence)
' requesting them to consolidate their various proposals on'QA implementation plans and independent review / assessments into one single document.
4.
After a revised, consolidated proposal is received from CPCo, the staff would schedule two meetings in Midland to present the staff's position to CPCo and to interested members of the public.
Tentatively, this meeting was planned for the first week in January 1983.
MhMO 5.
The letter jointly prepared by Region III and NRR in response to CPCo letter #18845 (QA implementation for the soils remedial work) would not be issued.
6.
The Division of Engineering has the technical responsibility for choosing which of the three systems proposed in the December 3 CPCo letter should be added to the scope of the independent design verification to be conducted by Tera Corporation.
We conclude that, as a result of this meeting,' the only licensing action for NRR is completion of Item No. 6 above.
LBf4 will be coordinating with DE toward timely completion, IUIn.u -.

REFERENCE LETTER TO J W COOK, DATED DECEMBER 30, 1982, FROM NRC REGION III
?
REGARDING CONSTRUCTION COMPLETION PROGRAM l,
3 On December 2, 1982, Consumers Power Company met with Mr Warnick and other' p
members of, your staff to discuss the general concept of our proposed Constr. action Completion Program. The enclosure to this letter documents in j;
detail the Construction Completion Program, as requested at the meeting and in j;
your follow up letter (Reference).
!r Since our meeting, the program has undergone considerable development and evolution. Details have been supplied and more specific objectives and implementing methods have been established. Further details are still being developed.
While the Company expects the Program, as presently constituted,
.to be a workable and sufficient framework for future action, revisions may be necessary as future needs and experience dictate.
The Construction Completion Program is a positive step in the overall advancement of Project goals.
It represents the best efforts of Project management, support and quality assurance personnel. We believe it will produce an improvement in Project installation and inspection status, systems construction and QA implementation. The quality verification effort should provide increased confidence of the NRC that the plant.has been properly built. Other aspects of the Program, including the' measure to improve ongoing inspections and scheduling interfaces, should contribute to that result. This Program, together with recent Consumers Power Company commitments regarding quality assurance and remedial soils work, can establish a basis for improved i
> relations between the Company and the NRC Region group assigned to inspect i;. Midland. The Construction Completion Program demonstrates the Company's responsiveness to both NRC concerns and the particular needs of this Project.
It is our expectation that the Program, created out of a desire to enhance the.

Executive Summary The Construction-Completion Program has been. formulated'to provide guidance in the. planning and management of the design and quality activities necessary for
. completion of the construction'of the Midland Nuclear Cogeneration Plants Construction completion is defined in this Plan as carrying all' systems to the p
. point'they are turned over to Consumers Power Company fot. component checkout i
{
.and preoperational testing. The Construction Completion Program does not i
'. include the Remedial Soils Program which is treated in separate interactions 2-between Consumers Power Company and the Nuclear Regulatory Commission.
J
{
Background.
h The Construction Completion Program was developed in response to a number of.
1 management ccacerns that have been identified during the period preceding the dl initiation of the Program. The Midland Project had been proceeding at a high 3
level of activity as it approached completion. The final transition from a,rea A.
construction to system completion, using punch lists, has been difficult for 3
most 'nuclea r' proj ects. The Midland Project has not escaped these difficulties p
which have been compounded d'e to the congested space and the continuing u
' numerous design changes, both generally attributable to the age of the y
p Project. These factors lead to the need for improved definition' of work d
status, increased emphasis on overall Project objectives as well as continued
[f focus of construction and inspection resources on completiori of systems for 4
short-term milestones and increased effort to complete engineering ahead of 9
field installation.
M-0 The Midland Project has been criticized by the NRC regional office as not having met their expectations for implementation of the Project's Quality f.
Assurance Program. The result has been that the Project management has too often, during the past few months, been in a reactive rather than.proactive 3
posture with regard to quality assurance matters.
wi
In recognition o'f these conditions, management has. concluded that a change in b
approach was needed to effectively complete the Project while maintaining high Q
quality' standards.
j, Objectives a
h*
The development of the Program has: considered the Project's current status and b
recent history and attempts to address the underlying or root causes of the p
problems currgntly being experienced.
In order to develop the Program the Lj following overall objectives were established under three general headings.

Description ij The Construction Completion Program entails a numben of major changes in the i
. conduct of the final stages of the construction process and can be described h
in summary as a two phase process.
First, after certain necessary preparations, the safety-related systems and areas of the plant will be systematically reviewed. This first phase will be carried out on an area-by-area basis, but will be accomplished mainly by teams organized with systems responsibility and a separate effort to verify the J,
completed work. The product from this phase of the program will be a clear y
status of ren;aining installation work and a current inspection status which j
provides quality verification of the existing work. The teams organized to carry out this first phase will continue to function in the second phase as the responsible organizational units to the. complete the work.
j I
a In order to achieve its complete set of objectives,,the. Program contains a i
number of activities and elements that support and are linked to the two major j
phases described above. The major components of the Plan, which are discussed in more detail in the balance of this report, can be described as follows:
J J
.,A significant reduction in the construction activity in the safety-i.
related portion of the plant, material removal and a general cleanup will be carried out in preparation for insta11a' tion and inspection B
status assessment and quality verification activities.

,7 1-Schedule Status N
The Program was initiated on December 0, 1982 by limiting certain ongoing A
safety-related work ~ and starting preparat' ions for the phase-one work of status s
assessment and quality verification activities. Since the Program also has
]-
incorporated a number of commitments made to the NRC during the past few g
months, activities in support of these commitments such as QC integration into j
MPQAD and the recertification of QC inspectors, had been initiated prior to
- j December.
k Status and schedules for each, element of the Plan are enumerated in the text.
In general, preparation for th'a Phase 1 activities are underway and will it-continue through January. A pilot team.co develop the procedures and training 3'
requirements will be initiated during January.

on that system or partial system. Management will monitor both process-readiness and Phase 1 evaluation results.
M The major areas of contiuuing safety-related work are NSSS construction as

performed by B8M Construction Co, HVAC work under the Zack subcontract, the i
Remedial Soils Program and post-turnover punch list' work released to Bechtel construction by Consumers Power Company. The Zack work is currently limited

- until a recently identified question on welder certification is resolved.
1
]i During the implementation of the Program in 1983, the NRC Resident Inspectors can use the Plan to monitor safety-related construction activities at the site. Since a substantial portion of the Plan directly relates to commitments j
made to NRC management, Consumers Power Company intends to schedule periodic reviews of Program status and progress with the NRC.

the planning and quality activities necessary for completion of the construction of the Midland Nuclear Cogeneration Plant.
Construction completion is defined in this Plan as carrying all systems to the point they 4

are turned over to Consumers Power Company for component checkout and preoperational testing. The Construction Completion Program does not include the Remedial Soils Program which is treated in sepsrate interactions between Consumers Power Company and the Nuclear Regulatory Commission. The Construction Completion Program will be referred to as the Program in this e

PLAN CONTENTS The Program was initiated on December 2, 1982 by limiting on-going work on Q-systems to pre-defined tasks and preparing the major structures housing Q-systems for an installation and inspection status assessment and verification of completed work. The relationship of the major elements of J
the Plan is shown in Figure 1-1.
The sections of the Plan address the following major activity areas PREPARATION OF THE PLANT.(Section 2.0)
The buildings are being prepared for a status assessment and verification of completed work.
QA/QC ORGANIZATION CHANGES (Section 3.0)
A new QA organization that integrates the QA and QC functions under a Consumges Power Company direct reporting relationship is being established. As a part of this transition, the Bechtel QC inspectors are being recertified to increase confidence in the quality inspection 4
perfo rmance.

h PROGRAM PLANNING (Section 4.0)
~
The overall Plan for the t.ogram is being developed in two major phases.
The first phase includes:
A team organization assigned on the basis of systems is being developed to determine present installation and inspection status.
The inspection status assessment includes performing inspections on completed work to bring them up to date. A closely coordinated effort involving the construction contractor and Consumers Power Company (QA/QC, testing and construction) will improve quality performance.
The quality verification of completed work will be based, in part, on a sampling technique using re-certified inspectors as described in Section 3.0.
4 The second phase includes:
Following installation and inspection status assessment the team organization will retain responsibility for systems completion work.
g The QC inspection process of new work will be integrated with the systems completion work to ensure adequate quality performance.
PROGRAM IMPLEMENTATION (Section 5.0)
The first phase implementation of the Program will be initiated with a review of the process, procedures and teim assignments that will be used. The plan for verification of completed work will be reviewed separately. The teams will conduct the installation and inspection status assessment; verification ot completed and inspected work will
~
proceed, as plcnned, in coordination with the team effort. To11owing phase 1 completion of the first work segment, a management review of the plan ei, etiveness will be made.
In second phase Program implementation, the assigned team will plan and schedule the remaining work needed for completion including QC inspections.
QUALITY PROGRAM REVIEW (Section 6.0)
The adequacy and completeness of the quality program will be reviewed on an ongoing basis, taking into consideration questions raised by NRC inspections and findings by third party reviewers. The results of these reviews will be considered as part of the management review that i
are a part of the Program implementation (Sectlon 5).

1.
Establish direct Consumers Power Company control over the QC inspection process.
2.
Establish the-responsibilities and roles of the QA and QC Departments in the integrated organization.
3.
Use qualified personnel from existing QA and QC departments and contractors to staff key positions throughout the integrated organization.
t Recertifv QC Inspectors Ensure that those Quality Control inspection personnel transferring to MPQAD from Bechtel will be trained and recertified in accordance with MPQAD Procedure B-3M-1.
3.3 Description s
' Establish New QA/QC organization A new organization will be implemented under Consumers Power Company and will be described in appropriate Topical Reports (CPC-1A and BQ-TOP-1) and quality program manuals (Volume II, BQAM and NQAM).
Changes to these documents will be submitted to NRC.
Features of the new organization include:
1.
- Lead QC Supervisors report directly to a QC Superintendent who t
reports to the MPQAD Executive Manager. Any required support from Bechtel Corporate QC and QA' functions (except ASME N-Stamp activities) is provided at the level of the MPQAD Executive Manager.

a 6.0 QUALITY PROGRAM REVIEW s
a
?
~
6.1 Introduction The adequacy and completeness of the quality program is reviewed as part of the ongoing Project management attention to quality.,These i;
reviews consider any questions raised by NRC inspections or findings raised by third party evaluations.
4 g
6.2 Objective Address issues raised by internal audits, NRC inspections and third party assessments. Program changes, if needed, will be evaluated j
and, as findings are processed, will be factored into the Project p
work.
3 A
6.3 Description Consumers Power Company believes Midland QA program is sound. From time to time, questions arise on detailed aspects of the program or program implementation. The normal process of addressing these issues ensures that all necessary information is provided to NRC and that internal confidence in the program is maintained.
A The recent inspection of the diesel generator building has raised several issues of programmatic concern.
These are in the areas of material traceability, design control process, Q-system related i
requirements, document control and receipt inspection.
Project 9
management has directed that MPQAD provide an expeditious evaluation j
of these issues to be considered as part of the management review
][j prior to initiation of Phase 2.
Once the NRC inspection report is received and specified items are identified, these items will be addressed and resolved through the normal process of closing the inspection findings. Any corrective action or program changes will g
be implemented as appropriate in Project work on a schedule provided in the inspection report response.
l The Project will al'so receive, from time to time, findings from H
third party assessments (Section 7).
These findings or recommendations may also result in program modification or f
adjus tments. Corrective action taken by the Project will be implemented on a schedule stated in the response to these findings.

7.0. THIRD PARTY REVIEWS t
7.1 Introduction j
This section describes third party evaluations and reviews that have 4
i been performed and are planned to assess the effectiveness of design.
1:
and constr'ction activity implementation. Third party reviews being u
conducted as part of the Remedial' Soils Program are not included in
,j.
this activity.
7.2 Objectives 1
To assist in improving Project implementation and assessment of Midland design and construction adequacy,. consultants will be utilized.in order to:
0 Achieve a broad snapshot of current Project practices and
?
performance in relation to a national program.
3 E.
Provide continuous monitoring and feedback to Management of
. Project performance.
3 Identify any activities or organizational elements needing
'i improvement.
4 i
Improve confidence (including 'the NRC's and the public's) in s'
overall Project adequacy.
A 7.3 Description The use of consultants to overview Project design and construction f
activities with particular emphasis on construction is part of the t
J effort to improve the Project's implementation of the quality
.]
program. Specifically, the plan overview employs the use of consultants for three separate functions:
(1) To carry out a self-initiated evaluation (SIE) of the entire Project under the INPO
,I Phase I program, (2) to utilize a third party overview of ongoing site construction activities to provide monitoring of the degree of implementation success achieved under the new program and (3) to conduct a third party Independent Design Verification (IDV) Program.
i 1.
The INPO self-initiated evaluation was planned as part of an industry commitment to the NRC in response to concerns over nuclear plant construction quality ass,urance. For the Midland SIE, the. evaluation was contracted to be carried out entirely by a
third party, experienced personnel from the Management Analysis i
Company. '
l
?,
The evaluation was. performed by a team of 17 consultants Q
familiar with the INPO criteria and evaluation methodology.
Over a period of a month they interviewed Project personnel at various locations and observed work in progress. The initial results of their evaluation have been presented to the Company h

q-included as part of the evaluation report to be submitted first 1
to INPO and then to the NRC Re.gion III Administrator, together
~
~
with the INPO overview.
f, 2.
A third-party installation implementation overview is being 4
. undertaken using, as a model, the program developed specifically 4
for the underpinning portion of' the soils remedial work. The y-overview will be initiated by retaining an independent firm, 4
having considerable experience and depth of personnel in the j!
nuclear construction field. The consultant's overview team will h-be located at the Midland Plant site and will observe the work j
activities being conducted in accordance with this Plan on 1
safety-related systems.. The overview will continue for a period j@d of six months, after which the Project's cumulative performance will be evaluated. Based on'the overview team's findings, a g
determination will be made by the Company's top management on ly:3 what modification, if any, should be made to the consultant's scope of work. Findings identified by the installation overview s
team will be made available to the NRC in accordance with the procedures established for the conduct of independent verification programs.
3.
An Independent Design Verification (IDV) is being conducted by Tera Corporation.
..g
.The IDV is directed at verifying the quality of design and construction for the Midland Plant.
The approach selected is a review and evaluation of a detailed " vertical slice" of the Project design and construction. The design and as-built configuration of two selected safety systems will be reviewed to assure their adequacy to function in accordance with their
?
safety design bases and to assure applicable licensing commitments have been properly implemented. The field work done 9
i.n support of this activity will not take place until after Phase I implementation (Section 5) has been completed on the i
systems being reviewed.
3 The Unit 2 Auxiliary Feedwater System (AFW) plus another system n
to be selected with NRC concurrence, will be reviewed to fulfill h
the requirements of the IDV.

T Expand the protection of completed and partially completed plant systems and components until plant' start-up, to take into account any special considerations during the status assessment.
l 8.3 Description Procedures and instructions are provided in the Testing Program Manual to protect equipment during the on-goin's installation and test work. These will be extended to cover special considerations j
associated,with the Program implementation. Both. the pre-and post-turnover periods are covered. System and component integrity is p
ensured through existing programs and implementation of control and j
verification procedures.

In summary, these procedures and instructions require: Test i
Engineers to complete walkdowns of Q-Systems (in the auxiliary, j
diesel generator and containment buildings and the service water

pump structure), paying particular attention to systems / components 4
?,
that are.open to the atmosphere (eg open ended pipes, open tanks,
.t missing spools, disconnected instrument lines, etc). Systems that have been hydrotested but are not currently in controlled layup require action to place the system in layup. Layup will vary from system to system but in general will consist of air blowing to remove moisture and closing the system from the atmosphere.

GOVERNMENT ACCOUNTABluTY PROJECT I
l Institute for Policy Studies 1901 Que Street. N.W.. Washington. D.C. 20009 (202)234 9382 March 7, 1983 Mr. Darrell Eisenhut, Director Division of Licensing U. S. Nuclear Regulatory Commission Washington, D. C.
Dear Mr. Eisenhut:
On February 8,1983, the Government Accountability Project (GAP) attended two public neetings in Midland, Michigan on behalf of the LONE TREE COUNCIL, concerned citizens, and several former and current. employees working on the Midland Nuclear Power Plant, Units 1 and 2.
As you know, the large public turn-out for both the daytime meeting between Consumers Power and various Regional and Washington-based offices of the Nuclear Regulatory Commission (NRC) and the evening session between the NRC and the general public included spirited debate and lengthy presentations. These meetings, although highly beneficial to the education of the Michigan public about the nuclear facility being constructed in Midland, did not allow for the type of technical questions and detail about the Construction Completion Plan (CCP) in which GAP is particularly interested.
Therefore, I appreciate this opportunity to address a number of concerns
. that we have reJarding issues presented at the public meeting and contained in the detailed CCP submissions. In order to complete our own continuing analysis of the Midland project, I would hope that you can provide answers to and/or comments on the enclosed questions.
Pending further public meetings and detailed review of basic elements of the Constructiqn Completion Plan, I assume that your verbal requests,to Consumers Power (Consume ts) management to " hold off" on making any commitments will be translated inco a firm NRC directive. As you know, Consumers has had a history of misinterpretations and miscommunications in relation to many of the aspects surrounding the Midland plant. The public understood quite clearly-what your instructions were; if those have changed I suggest that you continue to express those changes to the public through the appropriate local media representatives.
I.
REQUESTS FOR FURTHE' INFORMATION A.
The relationship between the Washington NRC offices (NRR, DOL, etc.)
and the Regional management.and on-site Midland Special Team and Inspector.
It is unclear where the authority lines for approval of various elements of the Midland construction project are drawn. GAP investigators, staff and attorneys are continually getting unclear signals from the various regulation divisions as to who is making what decisions and when. Since it has been noted by the NRC staff itself that "(Consumers) seems to possess the unique ability to search all factions of the NRC until they 6 @, f u a, + y < -1 i

Mr. Darrell Eisenhut March 7, 1983 f
. have found one that is sympathetic to their point of view - irregardless of the impact on plant integrity,"V it seems critical to establish once and for all the authority lines within the NBC that Consumers must re-
,j.
spond to.
1
{
We are particularly concerned about the apparent transferring of responsibi-4 lity for the on-site inspectors and the Midland Special Section Team to the Reg'ional i+
Administration and Washington-based NRC officials. Although I am sure that you have j
read the testimony of Mr. Keppler, submitted to the Atomic Safety aind Licensing Board (ASLB) on October'29, 1983, and attached memorandum from the staff members 1.
that are more directly responsible for the Midland project, I have included them with this letter for your renewed attention following the results of the Diesel Generator Building inspection.
(Attachment #1.)
j.
U'-
There have been a number of incidents within the last several months where s
Regional personnel (RIII team or on-site) have indicated one answer pertaining to construction work, and then other action was taken after approval from NRR.
Several 1
examples of this that are fairly recent are:
1.
A February 8,'1983 conference call between Consumers, Bechtel and the
]
NRC regarding the discussion of loading sequence for pier load test j
and background settlement readings did not include any Region III per-i sonnel, most particularly Ross Landsman. Although I do not know the
}
details of his exclusion, I am concerned that he was not a participant g
in the call, or in the decisionmaking. process.
2.
At the recent ASLB hearings NRR and RIII personnel were asked about I
the projected timeline for consumers to approach the Feedwater Isolation q'
Valve Pit jacking work. RIII personnel seemed confident that work would not begin on this until at least late March or early April, yet work ac-tually was begun on the same day as the conversation, February 17, 1983.
3.
The NRC has taken a position that "no major discrepancies" have been found in the soils remedial work to date. Yet:
(a) two cracks, in-
.i cluding one 10 millimeters by 7 inches long, have been discovered in the d
valve pit.M (b) A February 15, 1983 memorandum from R. B. Landsman to R. F. Warnick ' identifies three specific concerns since the beginning of the underpinning work that -- to GAP -- indicate serious flaws in the perception of Consumers about the seriousness of the work'they are en-gaged in.
These include craftworkers not receiving the required amount of training, arguments with Consumers about techniques that show a pri-ority to deadlines instead of quality, and a major flaw in the Stone &
{
Webster independent assessment.

' Given our experiences with the NRC inspection efforts, I am particularly
- anxious to have the on-site /special section team members have as much direct input into the review / licensing process as possible. Although I do not always agree with their decisions or their actions, I am more comfortable with their version of the facts on the Midland site.

The guidelines and timetable by which the independent third-4
. party auditor will be chosen.z
[
' It is not at _all clear what guidelines, if any, your office intends to i;
employ in the review or monitoring.of the selection process for the third-i -
party auditor of the Midland facility. We are extremely distressed at the
' way that both Stone & Webster '(S&W) and the TERA Corporation were approved
)I-by your office.. We feel that the approval was more by default than by aggressive review of the proposals, contracts and criteria as presented to. the NRR office. Further,.it is very clear to us that the Regional per-sonnel' involved in the initial contact with the Stone & Webster organization gave the i g ression that S&W's on-site activities were authorized. Even if
.that impression was only technically incorrect, it is a serious breach of publi'c trust by the Regional staff.
We reccamend that your~ office adopt the prudent position that Consumers g.
follow the nominating process used,for Diablo Canyon's independent assessment.
Al-j
'though Midland's problems have not yet reached the stage of major public controversy such as Diablo or Zimmer, it. is clearly evident that the sensationalism of the prob-less with the soils settlement and the cost of the Midland facility will move it more into the public eye as it reaches coupletion.
]
If there was any doubt as to the active interest of the Midland community in regards to the Midland facility, the February 8,1983 public meeting should have dispelled that misconception. The community surrounding the plant is extremely-1 attentive to the issues and concerns raised by the nuclear facility -- the debate j
will continue. To choose another, more congenial approach to identifying the firm
?
that will be responsible for the completion of the plant would be a grave mistake j
in our opinion.

The resolution

of these issues has critical implications for the rest of the i

CoettENTS CONCERNING THE THIRD-PARTY REVIEWS j
It is our understanding that there are currently three separate independent 3
audits being conducted (or considered) at the Midland facility. These are:
ni 73 -
(1) The Stone and Webater Corporation's third party independent assessment of the soils remedial work activities. A February 24, 1983 letter from Mr. Keppler i
to Constaners outlines the scope of the S&W assessuient. It significantly broadens
]
the original scepe of S&W's review. As a result of the expansion of S&W's ij responsibilities, and apparently a close monitoring of their work by the RIII S
team, Mr. Keppler approved the release of additional underpinning work for j
construction. We request the following documents in, reference to the S&W approval:
$h a.
The criteria that NRC officials used to judge the adequacy of the d
initial S&W work.
}
1 b.
The methodologies which the S&W personnel are utilizing to provide d
their QA overview and assessment of the design packages, inspector '
requalification and certification program, and training programs.
1 h
c.
The details of the expanded work contract which will assses the y
actual underpinning work on safety-related structures.
t j
(2) The Independent Design Verification and vertical slice review being h
performed by the TERA Corporation.
We have recently received the detailed M
Engineering Program Plan from TERA on the Midland Project. Although extremely j
impressed with some of TERA's procedures, organisation an'd structure there are a number of areas which raise serious questions, j
a.
What specific reporting procedures does TERA have to fe'llow l
in regards to findings, corrective action reports, controversies 3-among their own staff over issues of noncompliance or questionable y
accuracy, and internal reporting. Figure 1-1 clearly indicates that n

TERA intends to notify thNRC at the same time'as Consumers, but e
~,
at[the February 8 meeting there was a very. clear. example of that
- not actually happening because of misecomunication. between TERA and the 5
NRC.
j'
'b., What is the difference between a Corrective. Action. Report as referenced
'in the QA Audit Procedures and a Non-Conformance Report as required 4
3-by 10 CFR Part 21.
( A similiar " informal" nonconformance. reporting
[
procedure at the Willian' H. Zinumer plant caused innumerable problems
~
i for both the NRC'and the licensee.).We would ask that the C.A.R.'s be forwarded to.the NRC, or preferably be written up as NCR',s inunediately E
upon identification of an item of non-compliance. Any discretion
~between informal and formal procedures should be limited to the judgement-of the NRC.

Who controls the Administrative decision making process between k
Consumers and TERA over specific points of technical controversy?

What documents will be forwarded to the NRC in support of the 4
various findings - whether' favorable or unfavorable - during 'the A
course of the two vertical slice reviews?
1
)
(Further comments and questions about the TERA plan will be forthcoming
. i m-3 under separate cover when we are able to finish our review.)
f-6 a
J (3) The overall independent third-party assessment. Instead of providing t
j your office with our detailed ( and lengthy) analysis of the flaws and O
shortcomings of the CCP as introduced by Consumers in the January 10, 1983 letter and the public meeting we have decided to wait for further dr. tail to i
g be provided by Consumers on their plan. We are somewhat anxious about this, j-as we understand that there have been detailed discussions going on between the y
NRC and Consumers. As you know,
similar events at the Eisumer plant led to j
increased public skepticism and an even greater loss of confidence in-the j
NBC process.
1 We strongly encourage your office and the Regional Administrator to f
[
consider the process of choosing a third-party auditor as important and delicate J
as was the process at Ziauner.
If there is to be a " clos'ed door" approach to 3
Midland we request that you articulate that at this time. If you do not we will assume that the NRC intends to follow a fully public process of nomin.ntion d
and selection, y.
Thank you for your time, we look forward to answers to our questions in the near future.

This question refers to a "Bechtel audit of Bechtel
,y construction and design' announced at the'5/20/82 ACRS meeting." During the 5/20/82 meeting,there was discussion of an " independent. design
- verification" conducted by Bechtel and CP Co.
We assume thct is what the j
t question; addresses.
s m
I' '
The Midlatid Independent Design Review Program conducted by Bechtel &
CP Co personnel (who were independent of the Bechtel Ann Arbor office and' l
CP Co Midland' Project) involved 3183 manhours of the personnel on the 1
I review team, at a cost of $204,100.
~
l
!j, The purpose of the Prograr was. to review Eechtel project engineuing i
activities to determine if design criteria are being correctly
)
implemented and if the design assumptions, design, methods and the design processes are satisfactory. As discussed at the 5/20/82 ACRS meeting,
/
CP Co decided that based on occurrences at Diabl'o Canyon and other plants, a design audit was prudent, even without a specific NRC request.
CP Co decided that such an audit could be optimized by using people who were knowledgeable about the system but were not working on Midland design such as Bechtel persocuel located in offices other than Ann Arbor 4
g or CP Co personnel that have not been involved in Midland. The Company I
also did not'at that time, nor do we as yet, know what NRC-staff i
requirements would apply to independent audits for plants that are in the constructio'n and licensing stage similar to Midland. The Company believes that the Bechtel-CP Co audit will be extremely useful either in confirs.ing the adeqhacy of design and construction, or, if problems are 4

To date the following plans have been made for an independent I.[
design and construction verification program on Midland.
CP Co Panagement decided that the Independent Design and Construction s
Verification Program should consist of two parts, and that both parts t
i should be integrated into one report under the jurisdiction of one subcontractor.
The first part is to be an INPO-cype evaluation. This type of evaluation
't1 has been under development since March of 1982 with INPO developing criteria to be used by the Utility Industry in performing their self evaluation. INPO evaluation teams made up of utility personnel and
.1 consultants have conducted evaluations of several pilot plants in 1982 a
and, in September 1982, issued the latest draft of the " Performance Objectives and Criteria for Construction Project Evaluations." In September 1982, workshops were held by INPO for utility and consultant personnel on how to i=plement the evaluation.
INPO has discussed the program with the NRC Staff and NRC Staff has taken part in training q
sessions and INPO pilot plant programs. Although tha INP,0 Evaluation Program was designed as a self evaluation program by the utility using its own employees in conjunction with assistance from other utilities or i
consultants, CP Co has decided to have the INPO evaluation performed by
~
non-CP Co employees to obtain an extra degree of independence in the INPO-tyye evaluation.

The second part of the Independent Design and Construction Verification 1
Program will be similar to what has b'een conducted en several plants
~
which were or are to be' licensed in 1982. This would be an in-depth review of a system which is important to safety and whose initial design q
required interfaces within the principal design organization and with bs I
another organization, such as the NSSS supplier. This type of program
../
has been accepted by the NRC Staff on other plants. The contractor who
,j '
-will perform the independent, in-depth design and construction t
,1 verification will be required to. meet the independency criteria provided f
in Chairman Palladino's 2/1/82 letter to Representative John Dingell.

6 Spec's, drawings, develop tentative assign =ents and schedule). There will then be more detailed planning of the above, with a plant tour and e
5 identification of interfaces. The actual evaluation will consist of 4
e int.erviews, reviews of material provided, observation of activities, j
discussion of findings within the team, and drafting of performance,
evaluations.
J Part 2 The INPO evaluation team will. include one or more members who are employed by the Contractor doing the Part 2, in-depth review. They will assist in the INPO design review aspects, and use the information from the INPO activities to assist in determining the system to be verified in-depth.
The in-depth Part 2 design verification will confirm the design adequacy of an important safety system and will consist of,the following activities:
f Reviewing design inputs for conformance to system design a.
criteria and coc:mittments; 4

Some O preliminary activities such as training of review team personnel is ~ expected to start the last week in September 1982 and may commence before the additional presentation to the NRC. We expect that the Program would I be concluded approximately four months after it commences. ~ 12. For either of the structures mentioned, the independent design IJ and construction verification reviewer would not have to rely upon CP Co. O statements and analysis of internal wall conditions other than to utilize 3 the as-built drawings for the rebar. He could then use his own method of - i analysis to assess the adequacy. This is covered in the answer to ,r Question 6, Part 2, Ites (e). (Whether or not an independent audit would c pursue the rebar matter on these structures depends on whether the audit i encompasses them, and, if it does, whether the auditor judges Consumers Power Company's analysis to be adequate.) 4 miO982-0054f168 \\ 3 m, W G 9 O .ap f a w 4 8_ O Wi$u"O w.

5tbject: Ccnstruction Conpletion Schedule for I:idland On April 19-21, 1963, the DRC staff visited the iiidland Plant to evaluhtc construction cccpletion schedules. The reeting discussed the basis for Consuner's revised estinates of October 1984 (Unit 2) anc February 1985 (Unit 1). On April 20, 1983, the staff concucted an tour of both units to observe constructicn progress. The staff believes that your estinate of 14 renths to conplete preoperational and acceptance testing for both units is unduly optinistic. Recent experience for a single unit has indicated that this activity will requirc at least 24 conths to conplete. I'.oreover, the staff believes that your forecast does not realistically acccunt fcr large uncertainties in the work that nest precede start of critical path testing, and that this can be expected to add some renths to your schedule. These factors alone would infer that your October 1934 prcjected corpletion date is optinistic by at least a year. i Since the staff's visit, you have requested an opportunity te met with the staff to review the r,aterial previously ;,rovided as ucli as i to provide any additional inforcation for its further consideration in this r.atter. lle also understand that you plan to reconsider your schecoling priorities between Units 1 and 2 in light of recent actions by Do.i Chenical Conpany.

RECONMENDATION FOR NOTIFICATION OF LICENSING BOARD l In accordance with present NRC. procedures regarding Board Notifications, Ic the following information is being provided as constituting new infor-mation, some of which is relevant and material to the Midland OM/0L i proceedings. ii A. This information deals with the licensee's July 11, 1983, decision to stop all. Service Water Pump Structure (SWPS) related dewatering well drilling. The pertinent facts that relate to the stop work are as follows: U
- i 1.
On July 9, 1983, Bechtel Construction stopped drilling on well #521 when an obstruction was encountered at approximate elevation 619.5 feet. The licensee thought that the obstruction was most likely bedding material for a non-Q prestressed concrete pipe connecting the service water system to the cooling tower. 2. On July 9, 1983, Bechtel Construction stopped drilling on piezometer #LS-7 when an obstruction was encountered at approximate elevation 614.5 feet. The licensee thought-that the obstruction was most likely the mud mat from an electrical duct-bank. 3. On July 11, 1983, the NRC was informed of these two incidents by a conference call from the licensee. Midland Project Quality Assurance Department (MPQAD) decided to issue a formal stop work on all SWPS drilling after these discussions. 4 5 At the current time all drilling around the SWPS' remains stopped pending the licensee's completion of their corrective action to preclude recurrence. The events and the licensee's corrective actions are described in the attached letter from Mooney to Harrison, dated ~ j ' July 15, 1983. ~ _, '. a ti

There appears to be a continuing lack of attention to detail in the i - implemeuration of the remedial soil / underpinning programs". This is 1 .illustrated by the latest Stone and Webster weekly report No. 41, 3 which is attached. The report indicates problems such as untimely [ resolution of outstanding NCR's, not meeting the intent of design 1 drawings by extending the slope layback under the electrical penetration j' area (EPA), and not keeping the number of attached changes to a design drawing within workable limits. a f. On July 13, 1983, the Region.III staff performed an inspection of ' 0' the matters described in paragraphs A. and B. above and questioned j why soils work should' continue. The licensee's response, dated. { July 15, 1983,'to these questiens is attached. On July 20, 1983, subsequent to the licensee response, the NRC was ] informed that well #521 had indeed been drilled through the concrete y pipe and not into the bedding material as originally thought. j .aj. C. On June 29, 1983, following a review by the Senior' Resident Inspector ,i of welding procedures and observation of welding. performance demonstra-j tions, the NRC authorized the resumption of safety-related welding I work on the Heating, Ventilation, and Air Conditioning systems. The j work was initially stopped November 30, 1982, after a licensee audit 'i determined that the quality assurance program for welder qualification j and welding procedura qualifications was inadequate. A copy of our 1 authorization letter is attached. D. Although this is not a safety concern, the following information is provided to keep the Board informed. The lead welding engineer for remedial soils work allegedly instructed a welding rod room attendant 9 to change the rod return time on a number of weld rod withdrawal slips to conform to site requirements. Bechtel, when learning of the alleged a falsification, investigated, and fired the engineer on June 29, 1983. j The inspectors determined chare was no safety significance to this incident. 1 The welding rods, even though outside the heating ovens for-an extended i period, were kept by workmen in small portable warming ovens. In j addition, the rods were used in the welding of structures considered j temporary.

An excavation permit was prop,erly obtained and executed in accordance with all g ' applicable procedures before well drilling began. The location of the well was surveyed, verified and marked. as were underground utilities in the vicinity of Well.f521. The drill r'is was set up on a stake marking an underground utility rather than the stake designating Well f521. Spencer. White and Prentis and Bechtel Field Enmineers verified this as the proper _loca. tion. _0uality caneral verified that the drilline rie was-positioned. Jwithin allowable tolerances relative to this stak, When drilling proceeded, t an obstruction was encountered at approximately elevation 619.5 feet, t Drilling was stopped and gravel was found in the drill bit. It has been determined that the obstruction is most likely bedding material for a non-Q prestressed concrete pipe connecting the service water' system to the cooling'-.. ' ' tower. It is not known whether the pipe.itself was hit. An investigation is I planned to inspect the pipe,for damage. 4 In the case of piezometer #LS-7 ' drilling also occurred at a wrong location, i as a result of misinterpreting a Field Change Request (FCR). Again, the excavation permit system procedures were followed. Prior to drilling, the i field organization submitted an FCR to Project Engineering, asking for a change in the location of this piezameter, along with other wells, to avoid interferences with underground utilities and soldier piles. Project Engineering approved certain relocations, revised some proposed relocations, and added additi'onal relocation. _When tha FCR.came.back from Project Engineering approved. _the Field Eneineers and oc in=pmeene failed to notice the revised location for niaromatar #Ls 7 made by Project Engineering. As a result, the piezometer was drilled in an incorrect location. As previously indicated, the exca"vation permit pEocedures were followed in the above two incidents. We believe that the incidents resulted from work processes which, altho 4gh basically adequate. were not specific enough to avoid error. Corrective. actions are'as follows: A. We are establishing a new procedure for identifying location markers. Markare for utilities or obstructions will be a different_ color from.. 5 those marking drillina location. All responsible personnel vill be trained in this procedure before furth*er drilling is implemented. a B. We are reauirina Bechtel Field Ensinaars to verify==A aien for drill ~ ia locations before drillina commences. These individuals will be r ] responsible, on a single point basis, for making sure drilling occurs at the correct location. a C. Bechtel Field Engineers will be required to be present during field operations. D. Spencer. White and Prentis _(SWSP) has been directed to provide i additional personnel to assure full coverage of field operations. '3 E. The PQCI's will be expanded adding clarity to the related inspection
- activities.
This will require the pCE to coneare coordinates on the _ location marker to desirn doeur.ents.

Although we recognized the seriousness of y this incident, particularly in light of,the past drilling problems at Midland, MPQAD did not feel that the' incident alone warranted a stop work order. 1 i The.second incident,. relating to Piezometer #LS-7 was discovered on' Monday - July 11, 1983. The actual drilling began on Saturday, July 9,1983. Shortly af ter discovering'that the drilling was at the wrong location, a _ verbal' i h _ directive stopping all SWPS related drilling was issued. _A written direction i' ._f ollCVed Pnat aftarnaan. 4 - 'The two different location-errors, although caused by different circumstances, indicate that issues existed which must be resolved prior to continuing q drilling by Spencer, White and Frontis..The stop work order would have been issued by MPQAD on this basis alone, regardless of whether the NRC discussions had occurred on July 11, 1983. The corrective action described shave v111 be _in place before affected drittias unrk resumes.- TECHNICAL PROBLEMS ENCOUNTERED IN THE DRILLING OF WELLS #502 and #503 ) During the process of drilling devatoring Well #502, problems were encountered with materials caving into the hole. Because of our inability to keep the hole j, open, we decided to abandon this well. Dewatering Well #503 was started approximately the same time that probleas' u with Well #502 were experienced. Devatoring Well #503 has not experienced problems similar to those noted for Well f502. Nevertheless, because the two wells are only five feet apart, we suspended drilling on Well #503, and conducted a technical evaluation of alternatived for completing wells in that An acceptable approach towards completing Well #503 in accordance with area. existing procedures has been determined. 'f To avoid'enving of holes in this area, future holes will be drilled using one i of the following methods: (1),Rae of a " Backer" hammer: (tili; which allows _the hole to be cased _andjJAM3La.t_3ht_same ting, @ (2) Use of smaller diameter wella similar te those used in the interior of the SWPS. We believe either of these methods will solve the problem relative to the devataring wells.on, the ' east side of the SWPS. i a e O J ..__m._2. m m.. u. .~..

Item 8 - Notes of 6/27/83 Meeting Concern: Slope layback extending under the $' it 1 EPA. n Response: The limits of the drift north of Piers E/W 8 were at the discretion of the Resident Geotechnical Engineer (RGE) and the design drawings recognized the RGE's responsibility to authorize changes as necessitated by field conditions. Since the work was completed in accordance with quality requirements, a Non-l Conformance Report wa,s not issued. i T.

Item 3 ~ Notes of 6/29/83 Meeting Concern: Number of attached changes to drawings. i ) Response: MPQAD Soils had raised a question regarding the number of unincorporated changes to drawings in QAR #F-326 dated 6/20/83. This QAR is open. -As part of the closure to this QAR, consideration will be given to the fact that CPCo Volume II. Quality Assurance Program Manual Procedure #6-1 sets a limit of four attachments to a drawing for design documents prepared by i - CPCo. The final closure to the open QAR will satisfactorily address the quality concern related to the number.of unincorporated attachments to drawings. d Concern:- Use of FCR's and NCR's. Response: The project adopted a position in June, 1983 to clearly establish. t the requirement that NCR's are required for "after the fact" ~ FCR's; te. FCR's written to obtain approval of "as built" conditions which do not conform to design requirements. This position clearly indicates that the Field Engineer is responsible for causing an NCR to be initiated whenever it is desired to use an FCR to get approval of an "as-built" condition'which is not in accordance with desigti requirements. This requiramen.s has been incorporated in Bechtel Field Procedures FPD-2.000 as Revision 9. (This revision is in the final distribution as of this date.) In addition, MPQAD Procedure F-2M, Control of Nonconforming Itemis, has been reviged (Revisien 6-Effectivity of 8/29/83) and, requires 'an NCR to be-written for any item that is nonconforming'and "is at a point in the construction process where it should be in compliance with the applicable design or program requirements and it is not." These actions will programmatically require that NCR's are written for "after the fact" FCR situations. Stone and Webster indicated that the term " field as-built condition" in this item referred to the original constructed ~ conditions which are encountered during the underpinning work activities and not as a result of current work activities. I. Itas 3 - Notes of 6/30/83 Meeting Concern: Acceptability of the pumped grout test program for pier leveling plates.

DISCUSSION OF JUSTIFICATION FOR CONTINUING SOILS WORK Because of the concerns previously discussed in tEis letter, the Ragion III Staff has asked whether the soils work at Midland should be allowed to continue. We recognize and acknowledge the Region's concerns, which we share, with aspects of the performance of soils remedial work thus far. We are mindful of the need for continuing close attention, and extensive management involvement, to correct deficiencies and avoid errors. As previously described, steps are being taken i to corrset the deficiencies of co,ncern to the Staff, as expressed in meetings this week. On the question of whether these concerns warrant an overall stoppage of soils remedial work at Midland, we believe the answer is no. In our opinion, the concerns, while valid, do not run deep enough or are not videspread enough to call into question the overall integrity of the work, or the soundness of as-built hardware. In our cpinion the most serious of the various items cited.by the NRC are the drilling incidents. We acknowledge that there have been drilling problems at the Midland Site in the past; however, the two drilling incidents discussed above occurred after a period of successful implementation of involved procedures. The drilling rig mislocations that occurred appear to be caused primarily by too narroy a view of the inspection requirements and lack of specific verification of proper drill rig locations by both field engineers and QC personnel. Ihe entire corrective actions listed previously will, we believe, prevent recurrence i of this and possible related problems. In addition, the drilling has been 1 stopped until the corrective actions noted herein are implemented. l .y._.. .y._--. _-~- =.,..~~,,,-em,-,. --, c-
a ..u _ L ^ " ar.LF '....:.Ma >. sata. - 4 * ~, P:ga 8 -l + %nother item referenced by the NRC is an MPQAD stop work order related to drilling in'"Q" concrete.- Corrective actions, including the issuance of a revised PQCI, are being taken. This represents a case where our Quality Organization identified a problem and stopped work until corrective action has been taken. Additionally, the NRC had concerns about comments in Stone and Webster's Report No. 41. None of these items resulted in a Stone and Webster nonconformance. By contrast, when deemed appropriate, Stone and Webster has issued nonconformances -in carrying out their responsibilities as an independent ,assessor. We take seriously the need to consider all Stone and Webster comments, and where appropriate, initiate corrective action in our work activities. Without understating the significance of Stone and Webster's comments, we do not, believe any of' them question the basic adequacy of the work in the soils area.. ' In summary, while we have not achieved perfection, the quality of our final product is meeting design requirements and commitments. Our Quality Organization and Field Engineers are finding and correcting problems. The substantial upgrading of our quality effort in 1982 has achieved noticeable and acceptable results. The Stone and Vebster 90-day assessment of the underpinning work has not identified any major problems. Indeed, Stone and Webster determined that the initial under-pinning work, which constitutes the significant activities presently being accomplished, was being performed with a high degree of quality end since this report was issued, Stone and Webster has not advised us of any situation which would change this assessment. Based on all of these factors and in consideration of the overall quality' of the work, we 'believe the soils work at Midland should s continue. Continuing basic attention to detail by the Soils Organization with overview and involvement by Stone and Webster and NRC Region III will insure g immediate identification and res&lution of concerns and provide adequate assurance that the soils activities are successfully completed. \\ 00MU L a e + 5 e 4 g O# O 9 NRC/ work 3 O ...r-. m.w+..- ,+.a===.- .ve*==-* , = = - r- - +-e*" + -a m-~**+w-* ..**e'-

SUMMARY
OF. TEST PROGRAM L . A. Purpose of Test-To insure proper pressure grout placement on the permanent underpinning piers, a series of tests simulating leveling place. installations has been performed using,different concrete surface preparations, different methods for venting air, and different. grouting techniques for the placement of grout. t B. Summary of Test Results 4 All pressure grouted test plates provided a fully satisfactory grout' pad. None of the special surface preparations appeared to have had any affect on reducing the amount of entrapped air. Multiple in-jection points seemed to induce more entrapped. air than the single 3 injection point. An expanded metal /leadwool forming system had more disadvantages than advantages. The perfotmance of the Masterflow
- 713 grout and the equipment used all proved to be more than adequate for these tests.
C. Summary of. Conclusions The pressure grouting with Masterflow #713 provided a quality product equal to or better than drypacking with Masterflow #713. The overhead pressure grouting of steel plates can successfully be . performed using conventional materials, equipment, and methodology already available and in,use on the project. Successful pressure grouting can be accomplished using a single centrally located grout 3 i injection point thru the steel plates and by bulkheading around the i periphery of the plate with wooden forms. II. SCOPE OF TEST PROGRAM A. Objectives ? J' 1. To determine the quality of a grout pad that can be achieved by overhead pressure grouting. Of particular concern was the minimizing of voids created by air being entrapped in the grout ' at the interface between the existing concrete surface and grout surface 2. To determine the optimum methods of surface preparation, 4 formwork and grout placement. e am #me=*M

Test Facil'ities The simulation of actual conditions which exist under a structure t. being underpinned was accomplished by utilizing concrete blocks ~ (crane counter weights) cribbed by other concrete blocks' to create two' test bays. (See Exhibit D - Photographs #1 and #5). j D. Personnel The Mergentime personnel during grouting consisted of four (4) d' craftsmen,'a foreman, and a superintendent. The drypack crew consisted of five (5) craftsmen, a foreman, and a. superintendent. 1' In addition to the Mergentime personnel, observers were present from ~ Bechtel's FSO Field engineering and MPOAD for all of the grout Part time observers included Mergentime Field placements.

..n 1. s Page 4 III TEST PROCEDURES (Cont'd) The grouting was accomplished using an Airplaco model #HG-5, hand - 4 operated grout pump, in.2 five gallon plastic pail. The grout pump } was connected to the plate injection point by a flexible hose using j Chicago type couplings. Attached to the steel test plate injection l L nippis was a shut-off valve and a Chicago type coupling. (See l. Exhibit D - Photographs #4 and #7). Air vents were plugged only after a good flow of grout passed through them. After all vents j were plugged the pump was,used to apply and maintain a static pressure of 9 to 15 lbs. until the injection point valve was closed. y U.S. Testing ' as present ati che start of grouting and drypacking w 1 .each day and to take flow cone tests and to make strength cubes (see ' 1 Exhibit D - Photograph #3) for' verification of material character-N istics (see Exhibit C).. It should be noted that no curing was ) performed,on the grout test pads and that they were all stripped ] within approximately 20 hours of being placed. i D. Post Test Observations 'i All test plates were removed the day after placement. The grease bond breaker worked well, however, most ' test plate grout pads were dracked or otherwise broken during the process of removal. The results of all test plates grouted with Masterflow #713 were L satisfactory. The utilization of various patterns of specially cut grooves in the underslab concrete appenred to have.had no ir. fluence en relieving entrapped" air. In certain instances air bubbles were entrapped continuously across a cut grcove. The larger (over b" diameter and 1/8") air bubbles appeared almost exclusively on the plates with four (4) injection points. (See Exhibit D - Photograph
- 27). Since the first injection point generally filled the bulk of each test area it appears that these bubbles may be portions of a u
larger bubble that was for.ned when grout was placed fron a previous injection point. There is no definite pattern on entrapped air bubbles other than they appear to be radially oriented about one or ]' more of the three cubsequent injection points. Both the wood form and expanded metal /leadwool bulkhead methods i effectively contained the grout and provided adequate' avenues for escaping air. The wood forms left a neat uniform grouted edge while j the Expanded metal /leadwool created a void area approximately 3/4" back from che test plate edge. (See Exhibit D - Photograph #28). i n ) The wood plug system used to plug the bulkhead air vents worked well j at all locations where it was used. Although the leadwool plugs were satisfactory, in some locations they were pushed as much as 3/4" to L" into the grout pad itself and thus leaving a void. Also lesdwool was used at the only two vent areas that showed evidence of . - - grout leakage after grout shut-off. e T i 1 1 et e*m 7 / eh4 a' .' W.,(."'8 g oe yM -- T A g a.

'CONCIUSIONS 1 All pressure grouted test plates provided a fully satisfactory grout. pad ] for transfer of loading into or from an overhead concrete structure. j Based upon-the comparison of the seven (7) pressure grouted test plates, 4 it appears that'the single' centrally located injection point type of g test gives the best product. a d Test plate #7 had a special condition of a pipe extension of the injec-tion nipple up into a 1 " drilled hole in the underslab concrete. No r. 1 ^j advantages to this system were noted in the resultant underslab/ grout ij contact surface to merit further consideration. g; d Two drypack test plates were made using Masterflow #713 for comparison 3 purposes. Neither of these two test plates proved to be better than the pressure grouted test plates. Proper censolidation of the drypack on the far side of the test pl. ate and behind anchor bolts appears to be the g; weak. arcas for these plates. A third drypack test plate was made using a 1 to 1 sand / cement ratio which proved to be the best test. plate except i for a loss of contact area in the northwest corner, apparently a result of the plate moving during final stages of drypacking. 'j One problem noted from the prescure grouting and from two of the three q drypack test places, was.the elastic bowing of the b" steel test plates 4 resulting from the induced pressures. The least affected pressure grout .] test plate was #4, on which grouting was stopped with a static pressure, i i indicated at the grout pump, of approximately 8 to 10 psi. All other M plates were stopped at static pressures of 12 ps12 It should be noted 'l that only eight (8) expansion bolts were used to support the test plates ); and that no attempts were made to restrain or limit plate deflections ) 0 (bowing). It should also be noted that the static shut-off pressure was d measured on a 0 to 60 psi pressure dial attached to the grout pump, y discharge. (See Exhibit #D - Photograph #4). This static pressure: includes approximately six (6) feet of head between the gage and the a overhead test plate. Consequently ten (10) pounds per square inch pressure at the gage should mean four (4) psi actual pressure within the [] grout bed itself. Thus it appears that minimal pressure (sufficient to force grout to flow out the bulkhead air vents) is all that is necessary j to achieve grout placements.

~.. gy,.y g;, ~--, x . ~,. - - ~ a. .u - w ,p3- ~ y ] A Page 7 !j. 4 IV CONCLUSIONS (Cont'd) A ] An 'observatiori noted was that the pressure gage attached to the grout 4 . pump indicated high pressure peaks during the initial stages of pumping. 'j. This pressure could not have built up under the plates, since all the vents were open during this stage of pumping. This " peaking" was due to ]- - a combination of rapid pumping and line losses during the initial ] filling. As the vents were closed and pumping slowed, the pressures ]. stabilized in the line, reflecting pressures actually transferred to the grouted plates. (This " peaking" phenomena will be a. consideration in .j gage range selection in permanent pier grouting.) i ~ h No advantages were noted by use of..the expanded metal /leadwool system j ove.r the more conventional wooden bulkhe'ad system. A major disadvantage f vas, however, noted in that there was a definite loss in available grout 1 pad size in the leadwool system. Consequently production plates utiliz-4 ing this bulkhead system would require larger sized plates to makeup for g the lost grout pad area, t j The Union 76 multipurpose grease was used as a bondbreaker on the underslab c~oncrete surface and performed its function. The use of this m l grease as opposed to normal pre-soaking or the use of the weld crete could be expected to result in a larger amount of air entrapped in the grout concrete contact surface due to the grease being impervious and i thus not allowing any air to be absorbed by the concrete. On the whole the amount of small air pockets noted were about equivalent 1 to what might be expected on a vertically formed surface poured with air l antrained concrete. A quantitative value for percentage of lost contact surface, due to air or just no contact, was determined by physical measurements of the void areas larger than k" equivalent diameter. The 4 results of these measurements for plates #1 thru #4 and #6.thru #8 show a range of from 0.5 percent to 1.2 percent loss. Inclusien of all void ar2as less than 1/4" O should not amount to any more than double the N values calculated or in other words a maximum of 2.4 percent loss in total. ma d The hand pumping of the grout'was a satisfactory method for placement of ~ j the grout. It was an easy method to control the placing of grout as 3 well as being mobile and-requiring little in the way of support y facilities or maintenance during placement. 9 d The Masterflow #713 grout proved to be an acceptable mix in terms of its O net physical characteristics as well as the finished product. It should d be noted that although the Mergentime Procedures for grouting (MCP 3 15.000) and drypacking (MCP14.000) were utilized as guidelines,' absolute J'l adherence was not expected, nor was it guaranteed by quality control inspections. In particular, no bonding to existing concrete was di desired, no grout placement plan was utilized, and no attempts were made /.. _to, properly cure the test plate grout pads.

7 K. L li' J : .:.ru w u.. w --- l# r t. .c Page 8 IV ' CONCLUSIONS (Cont'd) (! - It should be noted also that the expansion anchor bolts were installed at varying depths and in several instances spacer washers had to be utilized in order to tighten the nut without bottoming out on the the i threads. .The bowing or elastic bending of virtually all of the test plates was to j. be expected, but should not be a source of concern. Boving of the' test plates showed up on both the pressure grouted plates as well as 'the dry-packed ~ plates. To date, no problems have been noted in the Auxiliary Building Underpinning work with drypacked leveling plates.. Bowing of pressure grout plates will not be a problem either since the bowing can easily be eliminated by the installation of plate bracing before' grout placement. }v V.. RECOMMENDATIONS h ' Utilization of leadwool as a form of bulkheading for pressure grouting ' should be kept as an option for areas where the more conventional vood bulkheading can not be utilized. There may be instances during grouting where the use of leadwool will provide the best and most ^ reasonable means of stopping grout movement. Care will still have to be s exercised to ensure that use of leadwool does not reduce the required ~ 4 effective bearing area of the grout pad. An option, although not tested, that should nrova equally as good as the single injection point system would be a dual injection point system (At t/3 points down the center of plate). This system would use two grout pumps both of which are pumped either simultaneously in a manner so as not to form air pockets / bubbles as noted in Section III D of this report. 4 s Grouting pressure should be kept near the minimal required to obtain 1 grout flow through the air vents. To avoid possible plate bowing or excessive bracing of plates, slow stroking of the handpump to eliminate impulse loading should be utilized. p n a SOTP/ work 3 a 1 ~~r m. ,- y

{ Quality Control. Documentation and Recordi: 1. The implementation of nor,enformance tirending analysis as applicable to under- ] pinning activities was reviewed. 2. Reviewed CPCo Audit reports of Dudgeon and of U. S. Testing. -l 3 Lead Auditor qualifications were reviewed for the' U. S. Testing and the Dudgeon audits. 4. Cocpleted inspection reports were examined for the following activities: instal-1 1ction of anchor bolts, grouting, welding of jack stands, concrete drilling and rebar splicing. 5.* QC field inspections were witnessed. l-Observations, Construction - Load transfer at pier W10 caused slight movement of adjacent piers, particularly W9 which remaineo on active jacks until late in the week as a result of the building movement noted previously. A review of the data being p: epared and svaluated by resident engineering does not indicate any unusual pier or structure movement in this area. J

c c L 3 1 T ~ J. O. No. 14358. 1 I } Midland Plant i . Units 1 & 2 Independent Assessment of Underpinning. Weekly Report No. 41 -Iksident Engineering continues to evaluate all pier load-settlement and structurak m3vement data to assure that no unexpected problems are developing. ) 1 The Asse,ssment Team observed the results of the installation of several flowable grout test panels and two dry-pack test panels. A visual evaluation of the panels indicated no significant defects. Two small void areas were observed in one of the dry-pack panels. Based on these results the Assessment Team believes the Sub-contractor is capable of satisfactorily installing either the dry-pack or flowable grout materials. j \\ Cuality Control. Documentation and Records: 1. The trending analysis system implementation has been somewhat modified from its normal usuage for. application to the remedial soils work. N insure that maximum bsnefits are obtained the evaluation of data must be accomplished in a more timely l manner. l 2. All audit findings resulting from the Dudgeon and U S Testing Audits were answered i I in an acceptable manner. Implementation of a few items has yet to be verified by the audit team.
- 3.. Qualifications and certifications of the lead auditors involved in the audits of Dudgeon and U S Testing were in accordance with ANSI N 45.2.23 in all instances.
- 4. No discrepancies were found in any_of the inspection reports which were reviewed.
~ 5. 'Ihe QC inspections of Hiltibolt installatien and torquing were in accordance with the inspection procedures. 4 t i 'Ihe weekly Engineering and Construction Coordination meetings are becoming an effective forum for discussion of problem areas. However, timely resolution of outstanding NCR's continues to be a nagging problem. The organization involved must strive to significantly reduce the time required for resolution. During the week an NCR was written on weld rod filler material which was inadvertently 3 used up to 12 hours after withdrawlfrom the supply station. The specification was rscently altered to limit the use time tio 10 hours maximum. Of particular significance 3 l w2.s the fact that MPQAD discovered alterations to the weld rod filler withdrawal records j associated with this nonconformance. FSO reacted quickly to the situation by terminat-j ing the employment of the' responsible welding engineer. 3 I Nonconformance Identification Report 4 p NIR No. Description Date j 12 NCR Reviewed for Reportability' (0pened) (Closed) g-p under 10 CFR 50.55 (e) part 21. 6/16/83 i L I i 4 f

Lavelle reported the precedure for drilling and suppcrting the pre-dri*.ed 2 ft. diameter hole is being revised based on the' experience on the first pile installation attempt.. J. Gaydes.said a change request was processed to use g grout as the pile backfill rather than concrete. Y p Item 2 - E/W8 Reinforcing Steel Welding. Y D. Lavelle said that the two qualified welders have nearly completed this type of l welding for pier E8 hammerhead. Item 3 - Pier KC2 Dry-Pack. cy J. Gaydos reported that at pier KC2 the upper leveling plate dry-pack had been j removed after the initial cube brea,k strength did not quite meet the specification requirements. Rather than waiting or attempting an engineering resolution, the ]6 - material'was removed and new dry-pack installed. s. } Item 4 - Concrete Mix Design. j N. Swanberg stated that the SCN approving new concrete mix designs, including i.) superplastici:ed concrete,is' scheduled for release this week. P. Barry said K. Razden ( C P Co ) had discussed the proposed designs with him and the Team cj concerns were stated. K. Razden must approve any new mix design prior to release j as a project concrete mix.

- Item 6 - Auxiliary Building Benchmark Movement.
W. Kilker reported J.Darby and P. Barry discussed the measures taken last week to reduce the structural settlement shown en Unit 1 Auxiliary building as shown i j by the benchmark in the vicinity of pier W8. Apparently care taken in working -around the benchmark ccmbined with some pier re-jacking has reduced the settle-ment rate to that in effect over the past few months. m n 33.:-rr g r g~-_- g 7;...... 7. , mygm., #

R. Sevo and M. Blendy stated that a number of NCR's will be issued concerning reinspection of electrical conduit originally installed as non-Q but now re-inspected as Q. P. Majeski stated that it would be important to review these J-NCR's to determine if the'. nonconforming items were an indication of construction j quality on nonQ items, the result of as-built conditons or the result of diff-j Gring inspection criteria. G. Murray stated. that none of the NCR's to date con-carns the integrity of the system. Item 3 - Use of ECR's For Drawing Revisions. y-P. Parish stated that often drawings were difficult to review because of the 4 number of attached changes and the physical problem of looking on the back of j the drawing. In the past, these documents were kept in a binder.but CPCo requested 1 that they be attached to the drawings. E. Cviki will look up the current require - j m*.nts for reissuing drawings based upon the number of outstanding changes. It was y also mentioned that an FCR, etc. is usually written to approve a field as-built 3 condition prior to QC inspectionto prevent an NCR from being written. M.

1 Purpose k This meet'in's is held each day to discuss' items regarding the Independent Soils j Assessment at the Midland Pla ', Units 1 & 2. Discussion } Item 1 - Rebar Welding For E8. An NCR was written against the welding of rebar because'a portion of the weld-g ing was done with weld rod which was in use for more than the specified 10 hour ~ period. This situation inadvertently occurred because of two factors. The first being that the weekend shifts on which much of the work was performed were 12 ' hours, rather-than 10 hours. The second factor is that there has been a recent specification change cutting the allowable time from 12 hours to 10 hours. D. 3 Lavelle advised the Assessment Team that the FSO Lead Field Welding Engineer was 1 . terminated for altering the weld rod. withdrawal records associated with the E8 9 welding nonconformance described above. A ti
- Item 2 - Carlson Meters.
P. Barry questioned if the WJE procedure on Carlson Meters may need changing as j a result of an upcoming specification change. Item 3 - Pumped Grout Test Program. u . The results of the testing of grouting procedures of the first four test plates j showed satisfactory results. Three additional plates were grouted and one dry _j packe'd on June 29. During this test series, plate bulge as high as 3/8 inch was 3 noted. R. Sevo indicated that the MPQAD inspector noted pressures of up to125 psi during grout placement. There was some discussion as FSO had noted maximum i} pressures,of 12-14 psi. R. Sevo is to confirm his understanding of MPQAD's ob-3 servation. ,} a 9 i y a A. '. u; e. ,'I

E. Cviki provided copies of the pertinent pages defining the criteria to be used for reissuing a drawing based upon the number of outstanding changes. In summary these are: 45 days since approval of first FCR/FCN against the drawing; 10 days [l -have elapsed since the 10th FCN; and, 30 days since the 15th FCR, FCN and DCN, taken in total. ? tj Item 3 - Pumped Grout Test Program., j .R. Sevo indicated that the high pressures noted by MPQAD inspector during the j pumping operation were only instanteous " spikes" during the hand pumping oper-3 ation. M. Blendy indicated that the test panel for the dry pack did not go as i well as for the pumped grout. It was his understanding that the crew was not i as experienced as the crews actually performing the work at the piers. An add-j itional test panel is to be constructed using dry pack. P. Parish said that it ] was his understanding that the dry pack used for the test was not as moist as j that used at the piers.
