MONTi-LY STATUS REPORT NUMBER 9 PERIOD JANUARY 1,1984 THROUGH JANUARY 31,1984 I
1.0 INTRODUCTION
AND PURPOSE 1
Monthly Status Reports have been instituted by agreement between the Consumers Power Company (CPC), the Nuclear Regulatory Commission (NRC) and TERA to provide parties external to TERA's IDCV project team with up-to-date information relative to program progress and any important issues identi-fled during the reporting period. This report covers the period from January 1, 1984 through January 31,1984. A description of the scope, reporting periods and report issuance dates for Monthly Status Reports, as well as a summary of the background of the IDCV program were presented in the initial Monthly Status Report dated May 27,1983.
2.0 IDCV PROGRAM STATUS
SUMMARY
2.1 Programmatic Activities Attachment I provides on updated chronology of major project milestones. The project chronology from inception through the beginning of this reporting period con be found in the previous monthly status reports. Several milestones warrant special highlight.
On January 4,1984, TERA issued a report entitled, " Midland independent Design and Construction Verification Program: Structural Evaluation of the Diesel Generator Building."
A meeting was held on January 31,1984 with Stone and Webster representatives to generally discuss coordination and interfacing between their Construction implementation Overview (CIO) program and the Midland IDCVP. It was agreed I
to formally place each organization on distributi,n to enhance efficient execu-tion of both programs. Information transfer existed previously; however, not in a timely fashion. An increased effort will be made in the future to promote feedisock between the two organizations and enhance the focus of activities within the ClO and IDCVP.
The sixth OCR Status Review meeting was held on February 1,1984 at Bechtel's Ann Arbor, Michigan offices. Representatives from TERA, CPC, Bechtel, and the NRC participated at the meeting.
On February 10,1984, TERA issued a letter that discusses the future direction of the IDCVP. The current status of the Midland project was identified as a major factor offecting the planned progress, this due principolly to the fact that a po tion of items within scope are in process and, therefore, unready for a
" quality of the end product" verification. A limited modification of the methodology was proposed which is considered to provide enhancements to the overall program in meeting the original stated goals. Accordingly, the opproach includes:
e Maintaining the existing vertical slice approach to design verification by:
reviewing end products for majority of sample; reviewing engineering procedures and action piens and their implementation for the remainder of the sample where items are not complete.
e Postponement of the construction verification until com-
, pletion of Phase I of the Midland project Construction
! Completion Program (CCP), thus taking odvantage of the l ossemblage of relevant quality documentation by the
! Quality Verification Program (OVP). During the period of l postponement, conduct a verification review of selected OVP documentation processes to allow expedited docu-mentation and physical verification after Phase I of the CCP.
e Focused review of identified process-related issues result-l Ing from existing Findings and ongoing work.
I l
l 2
' Thus,~ the principal alteration involves verification of a limited portion of the design verification sample by reviewing engineering procedures and oction plans and their implementation for items not currently completed. It is estimated that l opproximately 10 to 20 percent of our sample would be verified in this manner, ;
and that 80 to 90 percent of our sample will continue to be verified with emphasis on the quality of the end product.
l Proceeding as such, we estimate completion of the design verification on or i oround July,' 1984. We envision a series of topical reports over the interim months. The construction verification will recommence at on oppropriate time commensurate with completion of Phase I of the CCP.
- We have cornpleted on ossessment of status of the IDCVP as measured against the committed scope shown on the review matrices documented in the IDCVP Engineering Program Plan (EPP). Attachment 2 provides a key for designating completion status on the EPP matrices which are included as Attochment 3. The information presented on the EPP matrices served as input to an estimation of project completion status which is tabulated on Table 1. The IDV and ICV are estimated to be 64 and 25 percent complete, respectively. A composite percentage completion of the IDCVP is 51 percent. These estimates are based upon the currently defined scope including all OCRs and Findings of record.
f 2.2 Design Verification Activities
- 2.2.1 Summary The' engineering evaluation of the diesel-generator building was released as scheduled on January 4. Emphasis continued to be placed on completing work previously initiated and dispositioning of OCRs.
2.2.2 Auxiliary Feedwater System Progress in January the AFW system review continued, os it had in the previous two months, by concentrating on the disposition of OCRs and completion of support-ing engineering evoluotions. Lower priority is being given to completion of other 3

, ,z engineering evoluotions. No new engineering evoluotions were initiated in
- January. ,
OCRs were resolved or otherwise dispositioned based upon receipt of odditional information. Section 3.0 of this report discusses OCR status.
In the civil / structural arco work continued in the completion of engineering evoluotions and evoluotion of previously received information. No new engineer-Ing evoluotions were initiated, although several evoluotions neared completion pending resolution of OCRs. The OCR meeting on civil / structural items tentatively scheduled for January 31 was postponed until further documentation could be made ovalloble to TERA prior to the meeting.
2.2.3 Standby Electric Power System Progress The engineering evoluotion of the diesel generator building (DGB) was docu-mented in a report issued January 4,1994. The report evoluoted the DGB as-built condition and concluded that the DGB is capable of meeting its intended performance requirements. The review of the balonce of the civil / structural topics continued in January, including the Standby Electric Power system protection features.
The draft engineering evoluotions for the diesel generator (DG) electrical load copocity, electrical load sequencing, and electrical load shedding have been i completed. Resolution of Confirmed item C-Il0, relating to the DG Indepen-dent lood tabulation, was initiated with a review in Ann Arbor of SCN 4082 and reloied -internal documentation during the lost week of January. SCN 4082 updates the information in FSAR Table 8.3-1 (List of Loads Supplied by the Class IE AC System), which provides input to electrical calculation GPE-l on DG sizing. The Independent load tab utilized plant single lines, logic diagrams, and motor control center schedules to determine octual load. Confirmed item C-Il0 identifies differences in lood constituents among GPE-1, Table 8.3-1, the plant drawings, and the independent food tob.
S
In addition, the draft engineering evaluations for the DG system interlocks, control systems, and octuation systems were completed. All diesel generator interlocks were reviewed, os well as the entire DG octuation subsystem. All DG instrumentation and controls required by criteria or commitments were reviewed for implementation. TERA personnel attended the public meeting at the NRC's offices in Bethesda relative to the Delaval diesel generator problem status and !
the Owners' Group design review and quality reverification efforts.
1 The draft engineering evoluotion of the fire protection associated with the diesel generator building is currently undergoing internal review. The draft engineering evoluotion of the DG ond de systems Technical Specifications has been com-pleted, os has that for the consolidated criterio and commitments. The review of the 125Vdc system is progressing, with the draft engineering evaluation anticipated to be completed in February.
2.2.4 Control Room HVAC System Progress The written response to Confirmed item Ce084 provided in the January 19, 1984 Bechtel letter has been reviewed and evoluoted, and the item will be further dispositioned in February. The verbal responses to Confirmed items C-097 and C-129 provide o basis for disposition of these items with minor additional information. This activity will be completed in February.
Approximately half of the engineering evaluations for the Control Room HVAC system performance topics are completed. Disposition of OCRs is progressing to support that effort. Of the 19 OCRs which have been issued,14 ore either resolved, classified as observations, or will be dispositioned in February based on information already received. Five OCRs will require additional review effort, one of which has reached confirmed status and the others are open.
The status of the structural review of the Auxiliary Building, which houses the system components, is discussed in Section 2.2.2 of this report. Structural ossessment of duct and support qualification is progressing with calculations for individual designs being currently reviewed.

2.3 Construction Verification Activities During the reporting period, the focus of ICV reviewers' efforts was directed ,
upon the disposition of existing Findings and OCRs. Activities necessary to further progress the ICV reviews within the sample boundaries of the IDCVP selected systems have been postponed until completion of Phase I of the Midland project Construction Completion Program (CCP) for selected components and commodities. This subject as well as other modifications te, the IDCVP methodology will be discussed with NRC and CPC at the February 29,1984 status review meeting. Details describing the future direction of the IDCVP were presented in a February 10,1984 letter from TERA to CPC and NRC.
Principal activities undertaken during the reporting period are os follows:
e Meetings with cognizant Midland site personnel were held on Thursday and Friday, January 12 and 13,1984, for the purpose of obtaining additional information associated with the following reported Findings and Confirmed items.
Finding /OCR F-047: Storage & Maintenance C-093:CR-HVAC Documentation C-094:CR-HVAC Physical Verification C-095:CR-HVAC Zack Welders C-096:CR-HVAC Documentation F-055: WPSs and PORs F-091: Honger insp. Training Program C-092:Gualification of Inspectors F-049: Cable Separation F-050: Cable Misrouting F-054: POCl F-052: Vendor Document Controf 7
o On Tuesday, January 31,1984, ICV program management personnel met with CIO management. The purpose of the meeting was to explore and understand how best to use each of the programs' outputs (CIO and IDCVP) so os to maximize information exchange and benefits of program octivities. As a result of the meeting, a better under-standing evolved concerning how best to integrate each program's efforts. Further discussions with CIO program management will occur periodically, e Significant information was received from Bechtel and CPC concerning existing Findings OCRs. These dato and information are currently being evoluoted by ICV program personnel as a first step in determining the ultimate disposition of offected Findings and OCRs.

SUMMARY
OF CONFIRMED AND RESOLVED ITEM REPORTS, FINDINGS REPORTS, AND FINDING RESOLUTION REPORTS Attachment 4 provides TERA's Tracking System Summary for Open, Confirmed, and Resolved (OCR) Item Reports, Finding Reports, and Finding Resolution Reports. This tool ossists TERA in tracking the disposition of issues as they progress through the review process. Items ' bot have changed status or that have been added during the reporting period are noted with on osterisk.
Attochment S provides retyped copies of current period Resolved item Reports (that have closed out Confirmed items), Confirmed items, Finding Reports, and Finding Resolution Reports. Several Observations are also ottoched. The following porographs discuss items which have changed status in the post month.
i During January eight new Confirmed items were identified, five potential Open items were resolved as Observations, and seven items were resolved or disposi-i tioned as a result of receiving additional information. Additionally, two new items were identified as Open items pending further review by TERA.
Of the eight new Confirmed items, one (C-141) was opened lost month, but was confirmed later based upon further review. It is concerned with the air quality for the diesel generator starting system. C-144 discusses concerns resulting from TERA review of piping analysis commitments and their implementation.
Confirmed item C-146 through C-150 are all associated with the Standby Electric Power system review. The subjects of these items are os follows:
l 8
e C-146 Failure modes and effects for the pneumatic control system for diesel-generators C-147 Diesel-generator lood sequencer i
C-148 Fire seals for penetrations C-149 Compliance with NFPA 12 C-150 Compliance with NFPA 72D l
Item C-153 discusses on opparent inconsistency among design documents related to control switches shown on the auxiliary shutdown panel.
Based upon further investigation by TERA two potential Open items were resolved without issuance of either a Confirmed item or on Observatinn.
The following Confirmed items were resolved based upon the review of addi-tional information provided by the project: C-025, C-039, C-040, C-074 and C-081.

DESCRIPTION OF CONCERN:
See attached SIGNIFICANCE OF CONCERN: ,
Failure of operator to take action quickly could result in total loss of AFW (taking into account single failure).
I RECOMMENDATION ,_ OR RESOLUTION X :
Ref.1 provides a calculation which demonstrates that the~ operator has over 30 minutes to take corrective action. This is a reasonable basis for assuming that operator action will prevent excessive overfill of the steam generator.

ATTACHMENT TO 3201-008-R-025 Description of Concern: The " Feed Only Good Generator" systenY may perform in a detrimental manner under conditions of steam generator tube failure followed by loss of offsite power. Its design would force it to direct feed to the " bad" steam generator only because F0GG logic directs feed to the steam generator with the higher pressure based upon a delta pressure measurement between the two SGs. Without prompt operator action, the steam-driven pump could be ficoded and rendered
-, . inoperable as a result of leaking primary coolant. The FSAR analysis
. ) ' assumes operator action (no time delay menticned) to " invert" F0GG and send flow to good generator such that the SG tube rupture is recognized and mitigated in sufficient time. The basis for this assumption is not clear. With a single failure of the motor driven AFW pump, all AFW may be rendered inoperable.

, DESCRIPTION OF CONCERN:A check of the maximum cable length for cable 2AB5526A (power to
. valve 2to-3970A) using the procedure of QPE-8 Rev. 2 resulted in a maximum length (408 ft) that is less than the stated actual installed length (435 ft) shown on the Circuit Schedule dated September 1983. The cable 2AB5526A appears to be undersized.
'Ihe calculation of maxinun cable length was performed using 5.8 anps (Ref.1) for max.
current in the 3/C #14 AWG cable. Several other cable lengths were checked and found to be satisfactory.
SIGNIFICANCE OF CONCERN: Cable may be 3Rproperly sized resulting in overheating and degraded performance over life, 'Ihe Bechtel check of cable lengths in the circuit schedule did not identify the undersized cable. 'Ihere may be other safety related cables which are undersized. ,
RECOMMENDATION OR RESOLUTION X :
Tera agrees with the Bechtel assessment that calculation OPE-8 is conservative for the specific }D/ application cited here. 'Ib further review the cable routing and length control process, calculation QPE-17, "httor Starter Control Circuit Sizing" was applied to scheme OAB4509 on diagram E-457 (Q) sheet 1 Rev. 6. Using the circuit schedule cable lengths, the minimur.. voltage required at the MCC for the control circuit to function was determined to be 400 volts . The appropriate MCC voltage available under full load running conditions was 426 volts (from VOLTANAL RUN dated 1-26-1983.)'Ihe cable lencths were satisfactory. 'Ihis OCR is therefore resch'ed.

IDVP(general)
DCV PROGRAM AREA OR TASK (IF APPUCABLE):
1 DESCRIPTION OF CONCERN: In performing the IDVP it was noted that some documents l (especially drawings) are difficult to read because of small lettering size, limited !
space to provide information, and poor quality reproduction. These problems are l 9eneric to the industry and Midland is far from unique in this regard. The concern is that users of these documents could make errors as a result of misreading the i information. One of the calculations reviewed in the IDVP contained errors that, according to project personnel, were due to this problem. In this case the error was compounded by the failure of the checker to iotice internal inconsistencies within the calculation.
SIGNIFICANCE OF CONCERN:
This item is classified as an Observation because the specific error was corrected when the calculation was revised in the normal design revision process. It is possible that significant errors could exist due to this problem.
RECOMMENDATION OR RESOLUTK)N X_:
Classify this item as an Observation. The purpose of this observation is to bring
, the concern to the attentio.i of CPC/Bechtel.

DESCRIPTION OF CONCERN:
OCR 3201-008-C-085 noted a series of errors in calculations. In reviewing calcula-tion FM-4117-28(Q), Rev. 2, a few minor errors were noted. They all appear to be simple transcription errors and therefore this item should be considered as an Observation. See attachment for list of errors.
SIGNIFICANCE OF CONCERN:
The significance of the concern is more in the apparent lack of adequate checking than in the error itself.
RECCMMENDATION OR RESOLUTION X :
This specific item is considered resolved by classification as an Observation; however, Bechtel should:
(a) Make the appropriate corrections to the calculation when the calculation is next
. revised or when required by CPC procedures.
(b) Consider this item in formalizing a response to C-085.

I DESCRIPTION OF CONCERN:
A confirmatory seismic analysis for the piping analyzed in the ref&enced calculation was performed by TERA. The approach taken differed from the referenced calculation in three significant ways:
't 1. The Regulatory Guide 1.92 grouping method for modal summation of closely spaced modes was utilized instead of SRSS.
- 2. As-built stiffnesses were utilized for supports in the 6 inch piping.
- 3. The static load equal to the zero period acceleration (ZPA) times the system weight was combined with the dynamic load up to 33 Hz by SRSS instead of selecting the larger of the two loads.
Then to check the modeling, another analysis was performed using the same methods in these three areas as those used in the referenced calculation.
The analysis using the same methods produced very similar results to the referenced calculation. The analysis using the methods stated above resulted in significantly different results. In particular, the inertial seismic reaction loads at certain supports increase by over 50%. Each of the three j differences in methods contributed to the differences observed at some support, l but the most prevalent cause of differences was the third item, i.e., combina-
! . tion of static ZPA and dynamic loads.
The magnitude of seismic loads is very small in the piping analyzed and the stresses are well below allowable limits; therefore, it is unlikely that this particular piping system would.ever require modification due to the increases discussed. The concern is that these types of increases could have an adverse effect in other piping systems.
SIGNIFICANCE OF CONCERN:
For the magnitude of seismic load in this piping system, there is no concern r that the results will significantly affect the support design. For other piping, L' similar percentage increases are a concern. It is recognized that the method used here to account for higher frequency contribution is in general very conservative. Any method used to correct the static analysis to reflect only the mass participation not included in the dynamic analysis would substKntially reduce many loads; however, the SRSS combination is a realistic approximation in.)ome cases, in particular for axial nozzle loads or axial supports in long runs. It is possible that such loads are underestimated using the referenced calculation methods. The effects of closely spaced modes and support stiff-nesses also need to be included as possible accumulative contributors to the total seismic response.

Fire Detection in Diesel Generator Rooms DCV PROGRAM AREA OR TASK (F APPLICABLEh Topic 11.12-2: Fire Protection for Standby Electric Power DESCRIPTION OF CONCERr* FSAR Section 9A.3.E.1 states that the Midland fire detection system complies with the balance-of-plant NFPA 72D batteries. NFPAand 72D is requires connectedthattoaan emergency secondary power (standby supply)provided b power supply be provided to the primary fire detection power supply, & that the secondary power supply automatically transfer to operate the system within 30 seconds of the loss of the primary power supply. NFPA 72D allows the secondary power supply to consist of one of the following: a storage battery with a 24-hour capacity; an engine driven gsnerator with storage batteries; or multiple automatic starting engine driven genera-tors. Fire detection for the diesel generator rooms is provided by fire detection devices that provide alarm as well as automatic actuation of the CO2 system. These fire detection devices receive backup power from the diesel generators, but only if manually added to the bus and then only if an ESFAS signal is not present. This de-sign arrangement does not meet the requirements of NFPA 720.
SIGNIFICANCE OF CONCERN: With an ESFAS-DG START signal, or if CO2 system has not been manually added to bus after low voltage condition starts the diesels, there is no fire detection or alarm capabilities in the diesel generator rooms.

Topic 1.4-2, Technical Specifications DESCRIPTION OF CONCERNi A review of the Midland Technical Specifications contained in Chapter 16 of the FSAR(16.3/4.8, Revision 47,12/82) identified several variances with the NRC's B&W Standard Technical Specifications (STS) (NUREG-0103, Rev. 4, Fall 1980).
The variances are identified on Attachment 1 to this report.
SIGNFICANCE OF CONCERNr At the present time, the Midland Specifications have several d required to assure that design and safety analysis assumptions are maintained.
This should.be. corrected during future licensing activities; nowever if tne proper attention is not placed on' Technical Specifications, the poteni.ial exists for~ invalidating some design and safety analysis assunptions.
___ OR RESOLUTION X :
RECOMMDCATION Because of the draft nature of the Technical Specifications and the fact that these issues should be resolved during the normal NRC review and approval, this OCR will be resolved by classification as an Observation. Accordingly, the noted Observation is previed for information to NRC and CPC and may _cerve as inout as the Tecn Snecs are finalized.

l ATTACHMENT 1 Technical Specification (TS) Description of Discrepancy .
-1) 16.3.8.1.1.b.4 The Midland TS includes a requirement for jacket water and lube oil minimum temperatures when the outside air tempera-ture is below some value. This specification is in addition to those in the STS. Because of limits on the diesel engine, the specifica-tions should be included but not correlated to outside air temperature.
- 2) 16.4.8.1.1.2.a The specification references Table 16.4.8-1 l which is not included. )
- 3) 16.4.8.1.1.2.a.5 The specification differs from the STS in that it allows loading to 525 KW in 60 seconds i after synchronization. The NRC requirement is that it be synchronized and loaded within 60 seconds.
- 4) 16.4.8.1.1.2.b The specification contains references to
, ASTM standards which are different from those in the STS. Although, later versions are committed to, there are additional standards that have been required of recently issued operating licenseessuch as ASTM-D2274-70.
- 5) 16.4.8.1.1.2.c.9 The specification does not define short time as 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> as in the STS.
- 6) 16.4.8.1.1.2.c There is no specification (16.4.8.1.1.2.c.14 in the STS) for verifying capability of the fuel transfer purp to transfer from each storage tank to day tank via installed lines. The STS includes cross-connect lines which are not part of Midland design but normally it is still re-qaired to verify capability of the fuel transfer system periodically.
- 7) 16.4.8.1.1.2.d The Midland TS do not include this specifica-y tion which requires tests to verify indepen-dence every 10 years or after modifications.
- e
Technical Specification (TS) Description of Discrepancy The Midland TS do not include this specification
~
- 8) 16.4.8.1.1.3 on reporting diesel generator failures.
- 9) 16.3.8.1.2.b.4 This specification for minimum jacket water and lube oil temperature appear more a.npropriate than those of specification 16.3.8.1.1.b.4.
- 10) 16.3.8.1.2.b.1 and 2 The values for minimum fuel requirements of the l
day tanks and storage tanks are included in this shutdown specification but not in the operating specifications (16.3.8.1.1.b). In addition, these numbers appear to be very high such that there is not much margin for operational and test conditions before the tanks must be re-filled to maintain operability ( e 7 gpm diesel consumption requires e 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> to drop below the minimum requirement if the tanks were full). In addition, it is not clear if these values account for unusual portions of the storage as well as water retention allowable values in the storage tanks. Additionally, Calculation FM-4210-22 Rev.1,Page 6 indicates 32128.5 gallons are required. These nunbers should be verified.
~
- 11) 16.4.8.1.2 The Midland TS do not include a reference to 4.8.1.1.3 like the STS. As indicated in comment 8 above, the Midland TS do not include a 4.8.1.1.3 section.
- 12) 16.3/4.8.1.3 These specifications are to be provided by later amendment and were not available for review.
- 13) 16.3/4.8.2.1 The specification does not include Applica-bility, Action or Surveillance Requirements.
- 14) 16.3/4.8.2.2 No specification is provided for AC Distribu-
^t tion - Shutdown.
- 15) 16.4.8.2.3.2.C.3 The wording "20% above the average at installation time" is not included in STS or other recent OLs. The NRC requires a maximum which is also much easier for the operating staff to verify.

- 16) 16.4.8.2.1.1
- The specification does not include the re-quired minimum voltage as per the STS. ,
- 17) 16.3/4.8.3 The specification for Electrical Equipment Protective Devices are not included in the Midland TS.
General The Midland TS has several variances from the NRC's STS, but most of these will be corrected during NRC negotiations prior to receipt of the operating license. Besides the limits, setpoints, and operational values not being available, most of the Technichl Specifications lack some of the plant specificity above the STS required to ensuresalid design and safety analysis assumptions are maintained. Examples are requirements for the Diesel Generator Air Start systems and more specific requirements for verifying battery load profile requirements. Because of this, attached is a more recent set of approved Technical Specifications which have re-cently received much review and attention from the NRC and even though~
they are BWR Techniccl Specification, much of the electrical sections are similar. Some of these specifications should be considered by CPCo prior to a final " Proof rand Review" copy of Technical' Specifications.

Accident Analysis Considerations (I.2-1)
DESCRIPTION OF CONCERN:
In the process of resolving OCR # C-025, a calculation for steam generator fill time (Ref.1) was reviewed. 'Ihe following discrepancies were noted:
A. It appears that justification for reliance on operator action as a design basis was based upon judgment prior to initiation of the referenced calc. We consider it to be good engineering practice to docunent itms such as this within cales supporting the design bases. Accordingly, cales of this nature should be documented in accord-ance with ANSI K45.2.11 4 and afforded appropriate design control.
SEE ATTADIMENT SIGNIFICANCE OF CONCERN:
None of these itms has a significant impact on the calculation results or on the disposition of C-025.

DESCRIPTION OF CONCERN Steam Generator (S/G) A1W isolation valva switches are arranged on panel 2C114 as shown below. Drawing J-909 shows dernarkations which imply that valves 3965A and 3970A isolate steam generator A while the other valves isolate steam generator B. 'Ihis implication conflicts with P&ID M-439 which shows valves 3965A and 3970B isolating steam generator A and valves 3965B ard 3970A isolating steam oenerator B. A similar apparent conflict exists on control board ICll in Unit No.l.
SIGNIFICANCE OF CONCERN:
'Ihe apparent conflict between the panel drawing and the P&ID could mislead the plant operator and result in operator error. It is supected that a 'ike problen exists on the main control board to C-11. (Drawings were not available to confirm this.) .
