1.

As requested by the staff, we have reviewed the applicant's response to

[

the NRC Interrogatories 1, 2 and 3, and the following are our review comments.

a.

Since the applicant has not conducted consolidation tests on samples obtained from the surcharged area of the plant fill (Diesel Generator Building), there are no results available for review for the Interrogatories 1 and 2.

s l

l b.

The applicant has indicated on page 3 of its response that the live j

load expected to be transferred to the foundation soil has been conservatively f

estimated to be 25% of the full design live load. In our opinion, the I

reduction of the design live load to 25% of its actual value for computation of settlement is not justified. We understand that dead loads of the 1

equipment, piping etc. have been considered as part of the live load. These loads constitute a major part of the live load and are permanent in nature, therefore, no reduction factor should be applied'for this part of the live u

load. A reduction factor may be applicable to the portion of the live loads such as moving loads (cranes, hoists, etc.) and their impacts. The applicant should separate the live loads in two groups (1) live loadswhich are permanent in nature (2) moving loadu or loads that change positions more often and then

'l apply a reduction factor to the moving load portion only. The portion of the live load in (1) should be considered in full in computation of settlements.

Further, a reduction to 25% appears to be too high. The applicant should pro, vide justification for such high percentage reduction.

2.

In the last sentence on page 3 of the response, the applicant has stated that the live load portion (.8kps in stages V and VI) consists of the approximate full live load of the roof, intermediate floor and grade slab.

Response to Nuclear Regulatory Comission Staff Interrogatories 4

Regarding Midland Nuclear Plant.

It is our understanding the 0.8 kps has been obtained by deducting Stage V load on 16 January 1980 (2.2 kips) from Stage V load on 31 December 1981 (3.0 l

kips) of Table 4-1A.

However, from the heading of Table 4-1A, it is clear that this table pertains to building load only, therefore, loads shown at various stages must be the dead load of the building only. The applicant j

should clarify this discrepancy.

SUBJECT:

REVISED HEARING SCHEDULES FOR MIDLAND i

Backgrcund On October 16, 1981, and following internal discussions with the Division of Engi-neering and (by telephone) me, OELD participated in a conference call with Consumer's legal representatives and the Licensing Board to discuss revise'd sched-ules for the Midland soils hearing. The instant hearing is directed to the CP level of information needed to deteristne the adequacy of proposed modifications to structures located on inadequately compacted fill. The revised schedule is L

requested by Consumers in order to better accolunodate their finnediate construction schedules (i.e., to address first certain limited remedial activities said to be

'A critical to their construction needs) for which it is perceived that NRC staff l

concurrence is possible prior to the hearing start.

~

Problem Alert 1he applicant considers the Auxiliary Building to be schedule critical. Because the remedial actions for the Service Water Structure and Auxiliary Building are quite similar (especially for initial preparations), the applicant proposes that the two reviews be combined where possible. The NRC staff agreed to review certain recent submittals made by Consumers and to indicate on October 30, 1981, just what construction activities are likely candidates. Two candidates identified during the discussion are (1) installation of the vertical access shafts for the Auxiliary Building and the Service Water Structure and (2) installation ofi freeze wall

'i within the deeper soil layers around the Auxiliary Building to serve as an under-ground dam during excavation beneath the structures.

It was agreed that the hearing for construction activities for which agreement could be reached on the Auxiliary Building and Service Water Structure would be held December 1 - 4, 1981. Hearing testimony would be filed November 16, 1981.

e It was.also agreed that the next hearing session after that would be December l'4 18, 1981, and would discuss (1) seismic models for the Auxiliary Building and Ser-

]

vice Water Stnicture, (2) the Borated Water Storage Tanks, and (3) possibly the i

y underground piping. Testimony is to be filed November 30, 1981. The hearing on the

.i Diesel Generator Building is deferred to January 5 - 13, 1982, with testimony due December 21, 1981.

No further hearing sessions have been established at this time, but several sub,jects remain. These include prenanent,dewaterbg, structural analysis and crack modeling for all structures on fill. Considering the present technical status, it is quite likely that significant carryover from the December and January hearing sessions will occur.

Under the initial schedule, the hearing session was to be completed on December 18, i

1981. Now, completion of the hearing sessions before the end of February 1982 appear unlikely. The OL SER, scheduled for issuance May 6,1982, many be paced by 1ssuance of the Board's decision.

i Problem The NRC staff has not opposed the applicant's request to rearran'ge the hearing topics 1

and schedules to accommodate the immediate construction impact concerns. The problem is that these immediate construction activities are merely preparatory to a larger construction step, namely actual construction of underpinning, At present, it would appear to be highly unlikely, both fr6m a technical review status and from a legal status, that underpinning authorization by the staff caa be granted by January 1, 1982, as needed by the applicant. The legal question involves whether staff concur-rence can be granted while the matter is still before the Board, and whether under-pinning constitutes a "significant hazards" consideration. The applicant's position is that 50.55(e) provides for cor.tinued construction and that structural foundations are not covered by principal architectural engineering criteria required by the CP.

If this larger step can not be taken in early 1982 as the applicant wishes, then our present redirection constitutes a " hurry up and wait" situation achieved at the expense of a longer hearing schedule and increased potential of impact to the OL review and SER issuance. The applicant intends to escalate its position that under-pinning construction can and must begin January 1,1932, to staff management.

TEAM'S TEN-VOLUME SETS (3) FINAL REPORT ON NRC STRUCTURAL AUDIT OPEN ITEMS (4) DRAWINGS FOR THE DIESEL GENERATOR BUILDING i

In the NRC's July 7, 1980 correspondence, Reference 1, we were advised of the Staff's intention to perform a seismic and structural design analysis audit of major safety-related structures as part of their review of the Midland application for operating licenses. The addit was subsequently held during the week of April 20-24, 1981 in Bechtel's Ann Arbor offices. In preparation j

for this audit, comprehensive written responses were prepared addressing the Staff's guideline questions forwarded by Reference 1.

These guideline i

l questions and our written responses were arranged into several bound ten-l volume sets which were used by the NI(C's audit team during the audit. At the i

conclusion of the audit five (5) ten-volume sets of the Midland structural audit questions and responses were presented to members of the NRC's review team to take with them.

As requested we are forwarding five (5) additional ten-volume sets to serve as the NRC's record copies. These complete sets (Enclosure 1) already contain the errata sheets of Enclosure 2 and the additional revisions contained in.

For those NRC audit team members who were provided with bound volume sets, we are forwarding copies of the errata sheets (Enclosure 2) which should be inserted into Volumes 2 and 3 of those 10-volume sets already in their possession. The errata sheets of Enclorure 2 have been reproduced on blue pages, except for the FSAR figures, to identify them as revisions.

I During a discussion with the NRC Staff and its consultant, the Naval Surface I

Weapons Center, held on May 28, 1981, the NRC requested drawings of the diesel generator building to allow preparation of an independent mathematical model of the structure for dynamic analysis. By copy of this correspondence to the Naval Surface Weapons Center, we are forwarding two additional sets of the

,j drawings and information identified in Enclosure 4. One set of Enclosure 4 drawings were previously forwarded directly to the Naval Surface Weapons

'+

ll Center on July 17, 1981. Included for use are the Blueprints C-1001 through

1 C-1009 and A-350'through A-352 which detail the structural features of the

<liesel generator building. /.lso included are two sketches showing the j

mathematical model and locations and weights of major pieces of equipment in this structure.

We believe this completes the outstanding items from the NRC structural design audit. The ten-volume audit sets of Enclosure 1 are now in their final form and no further revisions will be made to this document. The resolution of any remaining more long-term issues which may relate to the NRC structural audit will be documented by FSAR revisions or in separate correspondence to the NRC.

Interrogatory 1

!;4;j Define " acceptance criteria," as that tenn is used at page 3 of the it l4 Order.

d l

3 Answer i

i Acceptance criteria are the standards on which a judgement or decision is based. As used in the December 6,1979 Order on Modification, the f

d standards to be used by the licensee to make its judgment or decision that Il proposed remedial measures are acceptable was sought by the NRC for its review. This infonnation was required to be submitted by the licensee in order for the NRC to determine whether there was reasonable assurance that the facility, as modified by the proposed remedial measures, can be con-structed.,and operated without undue risk to the health and safety of the public.

i mp i

II (f

L'

. g 3

The NRC practice in perfonning radiological safety reviews is such that the tenn " acceptance criteria" has a wide meaning and it is this broader meaning that applies as the tenn is used within the Order. The NRC practice is to use a document entitled " Standard Review Plan for the Review'of Safety I

il Analysis Reports for Nuclear Power Plants," NUREG-75/087, for the radiological l

l safety review of applications for licenses of nuclear power plants such as the Midland Plant.

Each section of the Standard Review Plan (SRP) is organi-I zed into four subsections, and one of these subsections is entitled " Accept-ance Criteria". This subsection contains a statement of the purpose of the review and the technical basis for determining the acceptability of the j

design or the programs within the scope of the area of review of the SRP

i j

section. The technical bases consists of specific criteria such as NRC l

Regulatory Guides, General Design Criteria Codes and Standards, Branch Technical Positions, and other criteria. This subsection is further dis-cussed in the first section of the Standard Review Plan, which is entitled

" Introduction".

t To illustrate the tenn " acceptance criteria," refer to SRP Section 2.5.4II, page 2.5.4-3 and Section 2.5.5II, page 2.5.5-1.

SRP Section 2.5.4 is entitled

" Stability of Subsurface Materials and Foundations," and SRP Section 2.5.5 I

is entitled " Stability of Slopes." From these examples it is seen that 4

" acceptance criteria" for the pertinent geotechnical review areas would include, for each specific and important engineering feature, a thorough L

evaluation of the particular engineering aspect based on analyses of basic h

[;

data that support all conclusions. These analyses and basic support data l

are required to allow the Staff to conduct independent analyses and reach 0

[.

.c

, ind3 pendent conclusions on whether reasonable assurance of plant safety exists.

Interrogatory 2 State which "of the Staff's requests were directed [as of or before December 6,1979] to the determination and justification of acceptance criteria to be applied to various remedial measures taken" (Order at page 3) and which portion of each request was so directed.

l Answer Attached Table 2-1 lists Staff's requests that were directed to the

,j determination and justification of acceptance criteria to be applied to various remedial measures taken and proposed by Consumers. As of Decem-1

.1 ber 6,1979, the only remedial action that had been taken was the placement of the sand surcharge inside and around the Diesel Generator Building, which j

had reached the maximum height of 20 feet above final plant grade on April 7, N and which had been removed by August 31,1979.E The requests in

l Answer 1

j The reply to Interrogatory ti(d) identifies which of the licensee's 1

.j responses the Staff found to be inadequate as of December 6,1979, and the-l response to Interrogatory 6(f) explains why. The responses were inadequate, in part, because they did not provide the acceptance criteria, as defined in the response to Interrogatory 1, which the Staff requires for its radiological

[.l safety review. Consider, for example, 50.54(f) Request 4 which on March 21, J

1979 in part asked (1) what criteria the licensee would use to judge the q

acceptability of fill, structures, and utilities upon conclusion of the y

preload program. -(2) what extent of residual settlement would be pennitted, and (3) the basis for the limit. The licensee's tnost recent reply prior r

f,.

to December 6,1979 (Revision 3 to Amendment 72 dated September 13,1979)

I stated that the criteria and the extent to which residual settlements would m

m x

,m.,

a t be pemitted would be provided by December 1979.k Therefore, the licensee's reply did not include acceptance criteria and the Staff considered the

' response to be inadequate and the matter remains unresolved.

For further examples, refer to the response to Interrogatory 6(f).

Interrogatory 5 State with particularity each iten of infonnation the Staff requested up and until December 6,1979 with regard to acceptance criteria.

Answer The items of infonnation the Staff requested up and until December 6, 1979 with regard to acceptance criteria are given in the reply to Interroga-tory 2. -

Interrogatory 6 With regard to each iten of infomation identified in response to Interrogatory 5, state: (a) the identity of the request; (b) whether Con-sumers responded to that request; (c) the identity of the communication that the Staff considered Consumers response to the request; (d) whether the Staff considered the response adequate; (e) the identity of the communica-tion by which the Staff communicated its position as to the adequacy or inadequacy of the response; (f) the basis for the Staff's position regarding 3]

The licensee's response was ultimately submitted February 28, 1980 by Amendment 74; or about 10 months after the full surcharge for the Diesel Generator Building had been placed and 6 months after the sur-charge had been completely removed.

9-Jadequacy or inadequacy of Consumers response; and (g) the Staff personnel responsible for determining whether Consumers' response was adequate or inadequate.

Answer 4

With regard to each item of infonnation identitifed in response to Interrogatory 5 (which in turn refers to the answer to Interrogatory 2),

Table 6-1 responds to parts (a), (b), (c), (d), (e) and (g) of Interroga-tory 6.

Answers to parts (e) and (f) of Interrogatory 6 follow.

For those requests shown in Table 6-1 to be issued before December 6,1979, but for which replies were initially made after December 6,1979, refer to

.f the answer to Interrogatory 8.

Similar infonnation for requests identified in Appendix A is provided by Appendix B.

Regarding part (e) of Interrogatory 6, the means by which the Staff comunicated its position as to the inadequacy of the licensee's response was primarily by the issuance of additional questions on the same subject.

These followup requests are listed in Table 6-1.

For example,' 50.54(f)

Request 35 specifically indicated the response to previous Request 5 was unacceptable. It is not Staff practice to indicate acceptable responses to licensees, except by seperate request on a case-by-case basis. Such indi-

~

u cation of acceptance is typically left for issuance of the Staff's safety p

evaluation report for those responses which are of significance to that report.

The basis for the Staff position of inadequacy shown by part (f) of

}

Interrogatory 6 is that the licensee's response failed to meet the Staff's acceptance criteria as defined in response to Interrogatory 1.

Specific reasons for failing are given below, and typically include not being fully

{

responsive to the Staff's requests or insufficient submittal of basic data

(

to support the conclusions or positions submitted by the licensee.

Consumer's responses to 50.54(f) Requests 4, 5, 6,12 and 21(c) were g

inadequate because of missing infomation or data or the responses raised additional questions. The portions of these requests which were inadequate are identified by the followup requests listed under Column 6(e) of Table 6-1.

The response to 50.54(f) Request 13 is inadequate because Consumers has not completed its analysis of the. Category I structures affected by the settlement factoring in the effects of settlement (ie., cracks, modeling changes, and material properties changes). Consumers acknowledges the

~

continuing nature of their studies in their answer to Request 13.

The response to 50.54(f) Request 14 is inadequate because Consumers has not completed its analysis of the Category I structures affected by the settlement, factoring in the effects of the settlement (ie. cracks, modeling

)

changes, material properties changes). Consumers has provided some infor-

?

R.

mation on the cracks present in most Category I structures, but has not detemined the related load and the related changes to analytical models and material properties.

In addition Consumers has not detemined if the cracks will continue to propagate.

The response to 50.54(f) Request 15 is inadequate because Consumers has not acknowledged the fact that differential settlement as used in the load 6

combinations is not a self-limiting effect.

In addition we have not accepted the proposed fixes.

The response to 50.54(f) Request 16, although responsive, is of a nature that additional tvork by Consumers is required for an acceptable reply.\\.

B due to settlement. The reply defined no acceptance criteria, but only stated that the loads on components were within the allowables. The reply provides no acceptance criteria as to when flanged joints will be disassem-bled and the methods for detemining nozzle loads. Acceptance criteria for i

the allowable differential settlement for the 2-inch and smaller diesel

'l generator fuel oil lines was not addressed.

As noted in Appendix B, the response to Staff Request 40.106 was con-sidered to be inadequate. The response was in conflict with the response to Request 20. Specifically, the response to Request 20 indicated that a stress analysis for the diesel generator fuel oil lines was unnecessary

~

because of the inherent flexibility of small piping (11/2" to 2" diameter);

whereas the response to Request 40.106 indicates an extensive program for monitoring and analysis of this same piping would be perfomed. Consumers position needs to be clarified.

For reasons indicated by followup Requests 25 and 26, the response to n

Request 130.21 as noted in Appendix B was inadequate. Consumers did not complete the answer to this question to our satisfaction. Consumer's r

response refered to other 10 CFR 50.54 requests and responses. The evalua-tions of Category I structures have not been perfonned to our satisfaction.

r i

u-7 l

.h 13 -

The applicant has nct justified in full the proposed fixes and has not provided a detailed evaluation of its analysis and design.

The response to Request 130.23 as noted in Appendix B was inadequate i

because the current criteria requires the use of ACI 349 as supplemented by Regulatory Guide'1.142./ In addition the effects of the settlement (i.e.,

cracks, change in modeling, change in material properties) need to be fac-tored in the analysis and design of these Category I structures. Further-

~

more, the answer addressed only the internal structures to the containment building and-the auxiliary building but deferred any consideration for other Category I structures.

The response to Request 130.24 as noted in Appendix B was inadequate

]l because Consumers did not complete its evaluation of all Category I struc-

~l tures for the effect of the use of Regulatory Guides 1.60 and 1.61 in place of its proposed seismic response spectra and related damping values. The effect of settlement should be factored into Consumer's reevaluation.

f Certain Consumer's responses were indicated to be inadequate. Consumer's responses to Requests 362.13. 362.14 and 362.16 were inadequate because the Staff concern raised in these rd 3 questions were not to be fully resolved atil Consumers complete < Wtbul field and laboratory work. Ultimately these issues have been punued by t,he Staff in subsequent 50.54(f) requests

.as identified in Appendix B.

The portions of the resp. se to Request 362.17 which deal with predicted settlement are similar to the above in that field ek had to be completed before the issue could be resolved. The portion of the response pertaining to induced vertical stresses versus depth was unresponsive in providing needed specific data and results.

L Interrogatory 8 Witn regard to each item of information identified in response to Interrogatory 7 state: (a) the identity of the request; (b) whether Con-sumers responded to that request; (c) the identity of the communication that the Staff considered Consumers response to the request; (d) whether the Staff considered the response adequate; (e) the identity of the communica-tion by which the Staff communicated its position as to the adequacy or inadequacy of the response; (f) the basis for the Staff's position regarding adequacy or inadequacy of Consumers response; and (g) the Staff personnel responsible for detennining whether Consumers' response was adequate or inadequate.

Answer This answer is provided in Table 8-1.

Additionally, Table 8-1 includes items of infonnation the Staff requested before December 6,1979 with regard to acceptance criteria, but for which the initial reply by Consumers had not been submitted as of December 6,1979.

Regarding part (f) of Interrogatory 8, it is not Staff practice to

[

indicate acceptable responses to licensees, except by separate request i

considered by the Staff on a case-by-case basis. Such indication of accept-ance is the function of the Staff's safety evaluation report for those responses which are of significance to that report. The means most fre-quently used by the Staff to communicate its position regarding inadequate responses during the course of the safety review is by issuance of addi-tional questions on the same subject. Such followup requests are listed in Table 8-1.

u a

.s m

.i

. }

Parts (d) and (g).of 50.54(f) Request 24 involved review by both geo-technical and hydrologic engineering disciplines. The parts of Response 24 g

3 indicated to be inadequate were the subject of followup requests or an NRC interrogatory to Consumers identified in column 8(e) of Table 8-1.

These followup matters provide the basis for the conclusion regarding inadequacy

]

l by the Staff.

The response to 50.54(f) Request 25 is responsive to our request but is

~

not complete. Consumers does not address the effects of the cracks on the load combinations, the rationale to the proposed fixes for Category I struc-tures, the modeling to be used in the analyses, the justification for material properties used in the analyses and design and a comparison of the results with suitable acceptance criteria.

The response to 50.54(f) Response 26 is inadequate because Consumers has not considered the effects of settlement in its analysis of the Category I structures.

Consumers states that the effects of differential settlement on Category I structures utilizing corrective measures are negligible while they propose further investigations for the Diesel Generator Building. We feel that the effects of differential settlement (i.e., cracks, modeling changes, material properties changes) needs to be considered for all Cate-gory I structures founded fully or partially on the fill material.

The response to 50.54(f) Response 28 is inadequate because Consumers does not address the concerns identified in our followup requests 25,28 and

29. Consumers provides additional infomation on crack mapping but does not address analytical considerations, s

f

r s u+== a The response to 50.54(f) Response 29 is inadequate because the effects of the cracks have not been satisfactorily included in the analysis. How-ever, Consumers attempted to identify the cracks in these inaccessible areas. The Staff feels that the effect of the structural cracks in the 1

Category I structures should be considered in the re-analysis of these structures.

The response to 50.54(f) Response 30 will ba adequate if Consumers classifies the duct banks as Category I structures with no requirement for maintaining a pressure boundary for the cables within those ducts.

The response to Request 31 was considered to be inadequate for the reasons identified by followup Request 43.

With regard to the response to 50.54(f) Request 34, the buckling stresses due to earth loads, vehicular and railroad traffic, are based on unifonn soil properties. From the pipe profiles, it is apparent that this is not the case.

The responses to 50.54(f) Requests 35 and 37 are inadequate for the reasons stated in A. Schwencer's letter of June 30, 1980 and in " Summary of Aopeals Meeting of August 29, 1980 Regarding Additional Explorations and Testing of Midland Plant Fill," February 10, 1981.

Itens 1 through 8 on an enclosure to a summary of a 1/16/81 meeting are responded to by Consumers answers to Requests 17 and 34.

In regard to the response to Request 17, the criteria does not consider the buckling or crippling stresses due to high bending stresses in the large diameter thin wall piping. Also, there was not sufficient infonnation as to the total piping involved, the proximity of the non-profiled to the profiled piping, L

=

, =... ~pg

. the percentage of piping profiled or soil characteristict in the area of concern. Due to the changes in slope of some of the prof!1ed piping, it would appear that soil characteristics vary.

Again with regard to 50.54(f) Request 17, the rate of change of slope tj or the radius of curvature detennines the bending :tra:.y more than the overall deflection. This request was made on that tOjs. If a satisfactory 4

allowable stress and strain criteria is presented witii en ecergtable stress analysis, the criteria for the change in piping curvature would not be required. The response to Request 34 was previously discussed.

1 Interrogatory 9 Excluding the infonnation provided in response to interrogatory 5, state with particularity each item of information the Staff felt was nec-essary, as of December 6,1979, for Consumers to provide in crder for the Staff to have concluded that "the safety issues associated with remedial action taken or planned to be taken by the licensee to correct the soil deficiencies will be resolved." (Order at page 3).

Answer As of December 6,1979 the Staff had detennined that, because the Licensee had failed to supply certain acceptance criteria, it could not conclude that the safety issues associated with remedial action taken or planned to be taken to correct the soil deficiencies would be resolved. The Staff had not detennined, as of December 6,1979 "each item of information the Staff felt was necessary, as of December 6,1979 for Consumers to provide y

in order for the Staff to have concluded that the safety issues associated e

with remedial action taken or planned to be taken by the licensee to correct L

the soil deficiencies will be resolved' Order at page 3."

See also discussion of need for seismological information in answer ti Interrogatory 11.

The infonnation the Staff felt was necessary, as of December 6,1979

(

was essentially that identified in answer to Interrogatories 2 and 5, in-cluding Appendix A relative to acceptance criteria. It shoted be noted.

u 9

however, that prior to December 6,1979, the full extent of the plant fill settlement problem was unknown and was under review. For example, 50.54(f) i Request 12 from H. Denton letter of March 21, 1979 asked for documentation l

my i

l of the condition of the soils under all safety related structures and utili-ties founded on plant fill or natural lacustrine deposits. This same request asked for discussions of measures to be taken if foundation materials are found to be deficient. Const ** ' response to Request 12 (initially on p

April 24, 1979 and subsequently oy Revision 1 on May 31,1979, Revision 2 on July 9,1979, and Revision 3 on September 13,1979) provided infonnation which the Staff found not to be fully responsive and, therefore, unacceptable.

The basis for the Staff's conclusion on acceptability is illustrated by the issuance of followup requests which seek to have Consumers provide its design and criteria in sufficient detail to enable the Staff to conclude l

whether there is reasonable assurance of plant safety considering those ll' modifications. An example of this problem is illustrated by the issuance of Requests 41 and 42 by the Staff's letter of August 4,1980 in which the Staff's geotechnical consultant, the U.S. Amy Corps of Engineers, continue t

to seek basic infonnation and data not previously provided in Consumers responses regarding the fixes proposed for the Service Water Intake Struc-ture and the Auxiliary Building which the Staff needs to reach a conclusion on the acceptability of plant repairs.

l Certain items of infonnation, in addition to that provided in response N elt to be needed by the Staff to interrogatories 2 and 5 were probably f

Answer See answer to Interrogatory 9. Because the infonnation the Staff felt was necessary as of December 6,1979 was essentially that identified in answer to Interrogatories 2 and 5. -the answer to interrogatory 10 is essen-i tially provided by the answers to Interrogatory 6, including Appendix B, and by that part of Interrogatory 8 relevant to indicated Requests 24 through 35.

With respect to certain items of infonnation (a) through (f) identified in the answer to Interrogatory 9 with respect to underground piping and associated components, the answer to Interrogatory 10 is provided by Table 10-1.

l The answer to Interrogatory 10(f) follows.

f (a) The criteria for selection of the piping to be profiled appears to i

be based on the soils in the same proximity as being homogeneous.

There appears to be insufficient evidence that this is the case.

(b) Theresponse'to50.54(f) Request 17 stated that the stresses due to settlement would be well below the code allowable values as indicated in Table 17-2 of that response. Therefore, it was indi-cated that reedial action was not planned by Consumers. This is not adequate because (1) not all seismic Category 1 piping was profiled. (2) future settlements had not been predicted, and (3) the results of the surcharge program had not been established.

(e) The response to 50.54(f) Request 18 in July 1979 indicated no plans for a monitoring program if the settlements remain within the predicted range.

It was not clear as to the time frame and methuds for verifying the predicted ranges.

I Excluding the information provided in response to interrogatory 7, 4

I state with particularity each item of information the Staff feels, as of the h

date of answering this interrogatory, is necessary for Consumers to provide in order for, the Staff to conclude that "the safety issues associated with remedici sction taken or planned to be taken by the licensee to correct the soil deficiencies will be resolved." (Order at page 3.)

Answer The Staff has not completed its review of information submitted by Licensee relative to the proposed remedial actions.

It is therefore impossi-ble to delineate "with particularity each item of infomation the Staff feels, as of the date of answering this interrogatory, is necessary for 4

ConsumeT to prraide in order for the Staff to conclude that 'the safety issues associated with remedial action taken or planned be taken by the licensee to correct the soil deficiencies will be resolved.'

0 To illustrate this inability, consider two recent occurrences:

(1)On t

January 21, 1981 Consumers submitted a potentially reportable 50.55(e) g report advising of an error in the 1977 computer model used for the seismic

?

analyses of the Control Tower and the main portion of the Auxiliary Building.

y Pending further analysis by Consumers, it is not possible for the NRC to 4

assess the ability of the Control Tower to assume the additional load result-ing from the bridged support scheme proposed for the Electrical Penetration Area; (2) Consumers has also indicated that additional cracking of the m

g concrete ring base of the Borated Water Storage Tank has occurred during the full scale load test. The Staff is presently awaiting Consumers' assessment of this occurrence. It should also be noted that resolution of the matter of establishing appropriate seismological input, as discussed in th'e Staff's

(

letter of Octolpr 14, 1980 and in a December 22,1980 " Summary of December 5,1980 Mee'ing on Seismic Input Parameters," is deemed to be relevant to t

the staff conclusion that the safety issues associated with remedial action taken or planned will be resolved.

The infomation needed by the staff for its review of the remedial t

actions is essentially that identified in response to interrogatories 2, 6, l

7 and 8, plus Appendices A and B, with respect to acceptance criteria for

[

those response items indicated to be inadequate. In Table 6-1 and Aoppendix A, the indication of response adequacy by the staff is with respect to December 6, 1979. However, the present staff position may be ascertained from the indicated disposition of the associated follow-up questions. The occurrences and seismic matter discussed in Interrogatory 11 also needs to be satisfactorily resolved, i

Answer See answer to Interrogatory 11. With respect to the information needed with respect to underground piping, see Table 12-1.

With respect to the adequacy of iten 11a on Table 12-1, the Bechtel stress analysis appeared to be unconservative and did not give a true repre-1 l.

sentation of the actual stress in piping. There were questions as to which I

l profiles were used and the. justification for the boundary conditions assumed.

An ETEC stress analysis demonstrated much higher stresses than those in the Bechtel report. At the 1/20/81 meeting Bechtel stated that subsequent analyses had shown higher stresses for some lines.

Interrogatories 13 through 16. See separate objections filed by the Staff.

b Interrogatory 17 Explain and provide the basis for the statement at page 2 of the Order l

tnat "This statement is material in that this..ortion of the FSAR would have

Answer Information submitted as part of an application for licenses in accord-ance with 10 CFR 50.30 is " material" if that information would or could have an influence upon a safety conclusion of the NRR Staff. A material statement which is false is of concern if it could have resulted in an improper finding or a less probing analysis by the NRR Staff. As described on page 2 and i

Appendix B of the Order, had the NRR Staff relied upon the statement in FSAR Section 2.5.4.5.3 which states that "all fill and backfill were placed according to Table 2.5-9", it would or could have erroneously concluded that the fills and backfill placed for the support of structures and the Diesel Generator Building consisted of " clay" (Table 2.5-9 under " Soil Types") or

" Controlled compacted cohesive fill" (Table 2.5-14 under " Supporting Soils")

which had been compacted, as a minimum, to 95% of ASTM D 1557-66 T modified to get 20,000 foot-pounds of compactive energy per cubic foot of soil (see Table 2.5-9 under " Compaction Criteria"). The reality of the situation is that the fills and backfills beneath the structures and the Diesel Generator

~

Building are not " clay" or a " controlled compacted cohesive fill", but consist of a heterogeneous ciAture of sand, Clay, silt and lean Concrete, and the minimum compaction criteria implied as having been achieved by the quoted statement from FSAR Section 2.5.4.5.3 was not achieved. Therefore, a conclusion by the Staff that the fills and backfills were of a different l'

type or had been compacted to known minimum standards would have been erro-neous and would or could contribute to or preclude a more probing analysis

!~

or further questioning. Based upon the FSAR infomation, the Staff would or could have concluded that the structure was adequately supported, that it L

.- would not experience detrimental settlement, that its foundations would l

remain stable under both static and earthquake loading, and that the fill N

properties would be at least equal to design values provided in the PSAR.

The Staff's conclusion would have been relevant to the NRC findings pursuant to 10 CFR 50.57 (3) for issuance of operating licenses and would have con-tributed to a finding that there is reasonable assurance that the activities

. 1 authorized by the operating license can be conducted without endangering the d

health and safety of the public.

a) the admission (in response to 950.54(f) question #1 Q requesting identification of deficiencies which i

d) continued work on the diesel generator building while bd i

unresolved safety issues axisted, which precluded thorough consideration of Option 2 - Removal and Replacement Plan; and e) the failure to freely comply with NRC testing bh requests to further evaluate soil settlements remediation, inasmuch as such programs are not allowed time for in the new completion schedule presented July 29, 1980.

explanation regarding contradictions between the PSAR and.the FSAR reads as follows:

.t 4

?

The Midland FSAR was submitted to the NRC at an earlier point in the project schedule than would have nonnally occurred in

,j order to provide additional time for the operating license hearings due to the forecasted intervention. Consequently, o

some of the material required to be included in the FSAR was not available at the time of its initial submittal, or was supplied based upon preliminary design infonnation. As the design and construction continued, the appropriate sections of the FSAR were revised or updated to include the necessary information.

I Second, a portion of the application for operating licenses,

'i namely the FSAR, was tendered by CPC on August 29, 1977. The NRC l{

performed an acceptance review pursuant to Section 2.101 of 10 CFR J

("

Part 2, and by letter dated November 11, 1977 advised the Applicant l

that the tendered FSAR was sufficiently complete based upon all of Ll l'

the information filed, taken as a whole. The Midland FSAR was h

docketed on November 18, 1977. The remainder of the application,

'j namely the Environmental Report, was tendered March 1,1978 and 2

1 docketed April 14, 1978.

I u

It is not unusual for the Staff to initiate review of an FSAR l

{

without inclusion of all the material which will ultimately be required for completion of that review. Moreover, the difficulty associated with certain statements made in the FSAR was not a matter i

of information excluded from the early versions of the FSAR, but rather a matter of their accuracy.

.t

- Hoogi o

A, decision by the NRC to docket an FSAR and the establishment of review schedules are administrative matters for which the NRC's goal is to provide for completion of the licensing review consistent with the construction schedule. With respect to the Applicant's statement that "some of the material required to be included in the FSAR....was supplied based upon preliminary design information " the obligation of the Applicant to provide accurate infonnation under oath or affirmation pursuant to Section 50.30 to 10 CFR Part 50 is l

by no means waived by these administrative matters, regardless of when they occur. Similarly, the quality assurance requirements of

Appendix 8 to 10 CFR Part 50 which are applicable to the FSAR apply irrepective of any time table.

NCR QF 203 (Attachment 2) identifies three instances i

where user test reports for1ranular soil material did not meet specification gradation limits.

(1) User Test Report 0630:

the acceptance gradation Ifmits for material passing the sieve were 90%; the user test report showed 94% passing. This deviation was " accepted as is" based on engineering review of the actual gradation of the material supplied.

(2) User Test Report 1036: the acceptance gradation limits for material passing the h" sieve were 75-90%; the user test showed 91%. This deviation was rejected based on an engineering i

l review and material was not permitted to be used in "Q" areas, but l

the material was permitted to be used in non "Q" areas.

criteria was for '"commerical reasons" since the supplier could 1

supply material within these limits. The specification, however, F

l permitted material to be within 7 - 205. Therefore, the acceptance criteria or the user test report was more restrictive than the j

specification requirements.

~)

d In all three cases the in-process corrective action was acceptable based on a review of the facts. These three noncon-faming conditions did not adversely or directly affect resolution y

-.' s of the soil settlement issue.

Regarding the use of concrete for " expediency" in the electri-cal duct banks. area the following should be considered. Based on i

the IE investigation the lean concrete material in itself was not a matter of concern. The matter of concern was that the design controls did not verify if the substitution of concrete in this area would affect the design basis of the structure (i.e. interface between the electrical duct banks and the Diesel Generator Building settlement). The IE investigation found that the design interface and consideration between electrical and civil was not adequate to assure the necessary tolerance between the duct banks and the i

.i structure to provide free movements when settlements occurred.

'l g

The question of expediency was not the issue in IE investigation 1

Indeed, that option

remains viable today should that option prove necessary. As noted

in the Applicant's response to 50.54(f) Request 21, the continuation

of building construction would contribute to the additional costs

The Staff had expressed a j similar concern during the meeting of December 4,1978, as noted I at the end of the " Summary of December 4,1978, Meeting on Structural Settlement," January 12, 1979: The staff also stated that while attention to remedial action i' is important, detemination of the exact cause is also quite important for verifying the adequacy of the remedial action, j assessing the extent of the matter relative to other structures, j and in precluding repetition of such matters in the future. The Staff's 50-54(f) Request I which was issued March 21, 1979, 4 also noted the Staff's concern that such quality assurance reviews be perfomed. This was followed by 50.54(f) Request 23 on Septem- ./j ber 11,1979.

What is the NRC Staff response to Item 4 in Stamiris' supplement to contention 27 i A. The matters of grouting gaps prior to cutting duct banks and breaking up the mudmat were considered at a meeting between CPC,

< N, v.. 'r No. 882." (Attachment 3) These notes at page 3, paragraph 6 <f " p) k (.

The' building construction should continue, thereby providing more weight on the foundations. Any gaps between the footing and the mudmat would require grouting. The grouting would not be necessary prior to preload. It was pointed out that i from a safety and a butlaing distress point of view, it would be advisable to grout existing gaps prior to releasing duct banks. It was also suggested that the mudmat be broken up prior to preload. I Similarly, in the trip report by CPC (Attachment S) for this same ~l '1 November 7,1978, meeting, the following account of the above 1 discussion is given at page 3: I l i I l 1't i- ^ h

~ 3 discussion continued and it was concluded that Bechtel ~ "j would grout any gaps between the footing and soil after 4 the preload'had been removed.

With the benefit of hindsight, it would appear that initially k s not grouting and a more gradual lowering of the structure after 6 i l (h release from the duct banks would have been preferable, rather than [ s I the actual abrupt release of the structure.

In subsequent submittals in response to NRC Request 362.2, CPC provided the results of boring / t explorations which had been drilled in August and September of 1978 and additional explorations in 1979. The date when these borings were drilled occur after the site area fill had been placed. These late results and evaluation bf the boring information which CPC has documented did not indicate the presence of loose natural sands i beneath safety related structures.

J. .l - ~. .c l,. -2 .(. Setween August 1966 and June 1969. I was a Nuclear Safety and Radiation - Analysis Engineer in the Nuclear Safety Unit, Nuclear Division of the 1 Martin Marietta Corporation at Saltimore, Maryland. The purpose 'of this t[_ position was to perfom hazard evaluations for nuclear power sources -i applied in space missions. My primary duty was to detemine public { exposure to radiation for malfunctions occurring during the intended i mission. I also detemined means by which the hazard potential for a nuclear space systems could be mitigated to the extent that nuclear j safety criteria were met. ~ I conducted research with regards to the development of suitable criteria for permissable exposure levels and their probabilities, taking into account the dependence of acceptable a i risk on the benefit to be derived. My primar SNAP 29 (Systems for Nuclear Auxiliary Power)y assignment was with the project. - My evaluations of this nuclear power source included the formulation and application of .;j computerized models for the transport of fuel released at high altitudes, i in deep ocean and in shallow waters. I derived models for these release [ areas to incorporate the activity into human food chains and determined the expected ingestion dose, the number of people involved and the exposure probabilities. Inhalation dose was determined for radioactive 1 fallout from the high-altitude release. Cetween February 1965 and August 196G I was a Nuclear Quality Control. Engineer within the Electric Boat Division of General Dynamics at Groton, Connecticut. The purpose of this position was to provide control of quality for naval reactor systems, components, and shielding during the ( construction or overhaul of submarines by this shipyard. My primary area of responsibility was shielding. Duties included establishing procedures for the inspection of fabrication and installation of lead and i, polyethylene shielding, and resolving problems in complying with these or other shielding procedures. The position required a knowledge of nuclear t theory, S5W systens design, Bureau of Ships contract and design i requirements, non-destructive testing techniques, and quality control requirements. 8etween November 1963 and February 1965 I was an Aeronautical Engineer 1. for Nuclear Propulsion and Power at the George C.

This NCR is closed as previously addressed in letter GLR-01 001. For the material identified in Part C of the subject finding the field I j has provided justification as to why FMRs had stricter requirements than l those given by Project Engineering.

N.W. Svanberg d PURPOSE: To obtain formal recoemendations from the consultants. 1 ITEMS DISCUSSED: 1. Background Information Bechtel presented sectiement data for the diesel generator building. il The data indicated no si nificant change in the previous trends C ] except for the eastern most diesel generator pedestal which expe'rienced l significant additional settlements during the past sanch of (approx-imately 1 inch at the N-W corner, 3/4 inch at the X-E corner and 0.4 i'nches at the other two corners). It was noted that the soil cust pit was dug in etnia bay and seen of the diffurential settlesent i could be attributed to the pit. The remaining boring data was consistent with previous boring information. The possible corrective actions previously discussed were reiterated: a. No corrective action taken except grouting under foetings. b. Modify the present strip fuundations for the valls to a .j continuous mat foundation for the, entire building. I 'N g._

~_m _ m. _ _. _ a__._ . m.o.~...~.. 1 P g3 2 1-f c. Prelcad and consolidate the soil under the building. y d. A combination of Icess b and e above. Underpin the building to transmit loads directly to the undis-s. turbed soil layer. j f. Remove and replace fill. 2. Recommentations Soil boring data substantiated the jobsite observations by Dr. Peck i that the fill is settling under its own weight. There are only two suitable options to correct the situation: 1 a. Remove fill and replace with denser material. ,b. Densify ext, sting material in place. d-Ther'efore, the preload option is suggested to consolidate the { material in place. The soil data' indicate a nonhomogenous fill. Therefore exact amo.mt of preload and the consolidation duration i cannot be estimated from the laboratory tests, To predict the amount and duration of the preload, instrumentation of the soil movement is needed. 6 mo f,Q I i It was indicated that a 5-month period is available in the schedule %b*9 for preloading. Dr. Pack stated that it is likely\\that the settlement g,* will occur rapidly once the preload is placed, but that the additional settlement could not be predicted with any accuracy at this time. 1 A range of 6 to 18 inches was considered to be quite pessimistic. Dr. Peck recommended proceeding with the insturmentation and preload as rapidly as possible. 3. Other Options The other options were briefly discussed. Options a and b would not stop the differential settlement and there would still be C ij settlement of the underground utilities. The effects of the settlement may show up after several years, causing problems during plant ope ration. Underpinning (Option e) would only be necesnery in case of structural distress after the preload had been comp 1sted. a Underpinning prior to p*ticad would not help the settlement of the q soil under its own weight. It was not felt to be an adequate q solution. 4. ' Pond Fill 9 i The consult mts suCuested that the best sequence would be to place UCd DN the preload and then raise quickly the cooling pond water level to Tebca$ its operating level. This sequence would allow the consolidation N,W to occur as rapidly as possible. Otherwise, the additional water 1 j entering the soil voids will have to be forced back out, extending [ ] the consolidation duration. However, after further discussion it 'g was agreed to by the consultants to proceed with~ filling of the pond frendiately, because the n.wount of river water available for filling is restricted. <+ p$ l' l H ._.7._.

l.

to determine actual bearing capacity. Additional saeples from . borings af ter the preload are not recommended. 6. suggested Activities t The. highest priccity is to install the soil monitoring devices. The soil anchors at several depths should go in, first starting with 1 the SE corner of the building and then the piesometers could be hf l placed. The duct banks which appear to be restraining the building O'g ,i settlement should be isolated from the building as necessary. The qe$sj. l building construction should, continue, thereby providing more o weight on the foundations. Any gaps between the footing and the ? , inud mac would require grouting. The grouting would not be necessary D -i

l prior to preload. It was pointed out that from a safety and a*

' building distress point of view, it would be advisable to grout existing gaps prior to releasing duct banka. It was also suggested q that the mud r.at be broken up prior to preload. '1 7. Preload Details I k The preload height should be about 20'-0", approximately equal to , the depth of the material to be consolidated. Physical limits restrict the preload depth to approximately 23 feet. The preload rate is not critical and even distribution would be adequate. The preload should be stopped at 10 feet for about a week to watch the monitoring, and then increased to 15 and 20 feet as necessary. It ~ l was suggested that a 20-foot berm with a 30 degree slope be used aroung the bulding where possible. Frost protection for the area to be preloaded was considered appropriate if required by weather j; conditions. 8. Possible Cause 1 l Consumer's asked the consultants for the cause of the excessive

i settlement.

Dr. Hendron stated that there were in addition.co

j nonuniform fill, erratic properties which may have been caused by too much variation in lift thicknesses. Dr. Peck said that the exact answer may be extremely difficult to determine. He added that material placed dry of optimum would later, with the presence of moisture, tend to soften the materials.' He also added that refilling of excavations from existing fills tends to be less adequate than the original fill. He said large areas to be compacted s

are better than small areas' and gave'the example of the dike versus the Diesel Generator foundation area. 7 m I g i I

There is a possibility ~ ]\\. of hydraulic fracture. The monitoring information from the dike has shown no reason for concern. There has been no significant settlement since the 1-1/2-inch settlement in the southeast corner observed in early 1978. This is the best evidence that the dike is performing i satisfactorily. There also has been a detailed visual inspection made on the dikes wh'ich indicates no evidence of problems. 'l j

10. Liquefaction I

i There are some sand materials under the north side of the diesel j generator building. The boring blow counts in some isolated zones R indicate that the potential for liquefaction would have to be evaluated. Vibrofloatation is a possible solution for liquefaction 1 problems if they exist. ~ l

11. Proposed Instrumentation

[j** The proposed instrumentation to be used to monitor the structure, j soil, and utilities was discussed. The structure, including the ,1 generator pedestals, would be monitored by survey. Areas covered bypreloadwouldhaverodsencasedbysleevese'tendkastoavisible x point. Four of the existing cracks in the concrete structure will be monitored by electronic strain sages. The existing fill will be monitored by 50 borros anchors. The anchors will be placed at three levels within the fill'. There will also be some anchors placed outside of the preloaded area as settlement control..The ~ j borros anchors should be initially monitored on a daily basis. Sectiement p1,atforms will be'used through the preload to monitor I the. top'of ground. The pore water pressure will be monitored by 20 l piezopeter at approximately the same three levels, except that the s.and'longth is to be shortened to approximately 2 feet. 4 The utilities under the structare (condensate and service water .j pipes) would be monitored by drag through settlement devices. The [,1 accuracy of data is anticipated to be + 1/4 inch and a series of 4 readings would have to be made to develop a base line. Inclinometers ,l were proposed to monitor the lateral movement of soil and utilities ] but the soil consultants felt that they were not needed.

12. 51ab at Elevation 634'-0" d

The consultant suggested that grating be used inside the building instead of the compacted fill and slab to eliminate material placed above the foundation. The feasibility was to be investigated.by t ', Bechtel. 1 t V a 1

SUBJECT:

SumARY OF JULY 18,1979 M ETING ON SOIL DEFICIENCIES AT THE / MIDLAND PLANT SITE i On July 18,1979, the NRC staff met in Bethesda, Maryland with Consumers / Power Company and the 8echtel Corporation to discuss deficiencies in the '} fill used at the site for Midland Plant, Units 1 & 2. Also present were representatives of the AC?.S staff. Meeting attendees are listed in 2 Ecclosure_1. In response to NRC requests, the applicant has documented in detail the presentations given during this meeting. The presentations are contained in S. H. Howell's letter to J. G. Keppler dated August 10,1979. In view of the August 10, 1979 letter, no sunmary of the presentations is contained herein. Rather, additional discussion consisting of coaments _ and questions given during.and following the presentations are sunmarized. During the presentation regarding remedial work in progress or planned (item 3 of the presentations), the staff noted that underground piping from the borated water storage tanks and service water lines pass under rattroad tracks, and that these and other. piping are subject to loads due to construction cranes and other traffic. The staff requested the applicant to describe the design features and other measures which assure that such piping is not subjected to excessive loads. The applicant will i respond at a later date. .9 The appiteant noted that it is performing laborator/ investigations of a the stainless steel piping removed from the condensate storage tank. pi This underground piping was found to be heavily corroded. It was notrt 3 that the injection piping from BWST is of the same composition and is W also unprotected from electro-chemical attack. The test-pits in the H tank farm area which are being dug to investigate the effect of the Q air discharged from underground pneumatic lines was also described. p Results will be reported' shortly.

g c 6( ( ( ~r l y i C""' 16 !979 Consumers Power Company ~ i 4 The staff noted that the response to its 10 CFR 50.54 requests for ac:eptance 3' .l. criteria for remedial actions (e.g., questions 4, 6, etc.) had not resulted il in identification of criteria in advance of the remedial action. Rather the l reply notes that the criteria will be determined during or after the remedial,d'p aj action. The staff stated that this approach by the appitcant does not provide ! d N for timely staff feedback at the outset, but rather the staff must await results of the program to deterentne what acceptance criteria were used and j if they are acceptable. Thus, the remedial action is being conducted entirely at the applicant's own risk. The applicant's presentation of the permanent site dewatering system (presen-q tation item 3.3) noted that the system is not designed to seismic Category I requirements, but that the monitoring aspects of the systam are safety si The NRC staff noted that acceptance criteria for the dewate 'ng grade. ] system are given in the Standard Review Plan (Section 2.4.13, Revision 1) and requested that the applicant address Branch Technical position HMS/GS3 1, " Safety Related Permanent Gewatering Systen:s", Revision 1, attached thereto. i i The appitcant will respond in the near future. The quality assurance plan i for implementing the dewatering system will also be provided in future reports. l Bechtel described the structural and seismic analytical investigations being performed or planned for the affected structures (item 4 of the presentations). 1 The staff noted that further review of the acceleration (g) value used for site design has been impacted by staff manpower restructuring for the TMI-2' investigations 'and that use of outside contractors for the Midland seismic review is presently being considered. The staff also noted that its present i review indicates some areas of disagreement with the appitcant's proposed 'j loads ccabinations.and design criteria for SSE and differential settlement, and with the treatment of cracks in structural walls. The staff will further j docunent these and other positions at a later date. Bechtel reported (item 7 of the presentations) the results of its investi-e4 gations into the case of insufficient compaction of the plant area fill, and 'j identified five causes considered to be the most probable. The applicant noted its agreement with the 3echtel findings. Bechtel noted that personnel were not included as a most prooable cause because its review of qualifications 4 and expersience of both Bechtel and US Testing personnel had shown presence of -) sufficient education, experience, and training to carry out the tasks assigned. q The NRC staff noted that it disagrees with Sechtel's finding that personnel h qualification was not a probable cause, and stated that further review of the t basis for this Bechtel finding will be needed. 1 Staff consnents regarding the QA/QC aspects (presentation item 8) were based upon the applicant's 10 CFR 50.54(f) responsas to quest, ion 1 by d letter of April 24, 1979: F 1 i 4 )L m

(1) The applicant's response in item B.1 of Appendix ! (page I-3) 3 states its conclusten that " Specifications C-210 and C-211 provide l sufficient criteria by which to ensure that the fill is adequately a 4 placed to prevent excessive settlement." The staf* noted its

,j

. disagreement with this statement. The staff noted, for example, s that its IE investigations show that the specifications did not require qualification of equipment used to compact material, the lift thicknesses permitted were excessive for adequate compaction, gj the moisture control was unclear and the compactive effort to develop 95". of compaction was internally in conflict within h. Specification C-210. .i (2)' The applicant's response in item S.2 of Appendix I (page I-3) i noted that letters, TWX's, telecons, and memoranda are often i used to clarify the intent of the specifications, and that "it is possible" that in some situations the clarification provided j through such methods may have modified the :pecification without j formally changing the wording of the specifications. The staff comented that a more positive statement appear 1. to be warranted based upon the findings of IE. Numerous examples where telecons and memoranda were used to change the requirements of the speci-fications without revising the controlled document itself was cited in IE Inspection Report No. 50-329/78-20 and 50-330/78-20. l IE found that not only did these memoranda change the require-ments of,the specifications, but in some instances, conflicted = with previous engineering directives. ] (3) The staff noted that its review of QA aspects was centinuing and that funther requests for information would be issued. At the conclusion of the presentations, the NRC staff noted that the information presented was significant to the present review, and requested that the applicant (ocument and submit its presentations, including copies of the viewgraph slides used. 1< 'l ~ l-/,, N r edu
