MONTFLY STATUS REPORT NUMBER 10 PERIOD FEBRUARY 1,1984 TFflOUGH FEBRUARY 29,1984

1.0 INTRODUCTION

AND PURPOSE e

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 io program progress and any important issues identi-fled during the reporting period. This report covers the period from February 1, 1984 through February 29,1984. 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 an updated chronology of major project milestones. The project chronology from inception through the beginning of this reporting period con be found in the previous mr'bly status reports. Several milestones warrant special highlight.

On February 10,1984, TERA issued a letter that discusses plans for completion of the Midland IDCVP. A summary was included in the ninth Monthly Status Report. TERA proposed to include this item as a topic for discussion at the I

r regularly scheduled public OCR Status Review Meeting which was to be held on February 29, 1984; however, the NRC requested a postponement of this discussion until March 13, 1984. The NRC's request was mode as a result of another request by the Government Accountability Project (CAP) to hold the meeting in Bethesda, Maryland. Accordingly, the March 13, 1984, meeting was noticed on February 27,1984. ,

The seventh OCR Status Review Meeting was held as scheduled on February 29, 1984, at Bechtel's Ann Arbor, Michigan, offices. Representatives from TERA, CPC, Bechtel, and the NRC participated at the meeting.

2.2 Design Verification Activities 2.2.1 Summary During February, emphasis was placed on dispositioning of OCRs and completion of previously initiated work while also initiating new tasks where appropriate.

Work was begun on reports covering the system performance requirements for the AFW and CR-HVAC systems.

2.2.2 Auxiliary Feedwater System Progress Work on a report covering AFW system performance topics was reinitiated during February. A preliminary draft was complete at the end of February and will be finalized as OCRs are dispositioned and engineering evaluations are completed. Engineering evaluations for nearly all AFW topics have been initiated, although some remain only partially complete because of the need for additional information or responses to OCRs.

i l

OCRs which were resolved or otherwise dispositioned a e discussed in Section 3.0  !

of this report.

In the civil / structural area, progress was made in the disposition of OCRs as the project submitted additional information in anticipation of the March I meeting to review these OCRs. All engineering evaluations in the civil / structural area I have been initiated but remain incomplete pending resolution of OCRs. l 2

2.2.3 SEP System Progress Dispositioning of OCRs continued to progress in February, with additional information received to address some potential load discrepancies for OCR C-l 10. A meet:ng was held with Bechtel mechanical personnel to receive a briefing on the new calculation on DG exhaust backpressure, prior to its release

' to TERA for OCR C-Il2, and to discuss information required to address OCR C-133 on the DG pneumatic control system operability requirements.

Written responses have been received for the following OCR items and cre being reviewed and evoluoted:

Bechtel

. OCR No. Item Letter Date C-109 Override of 60-sec coastdown interlock I/25/84 C-llI Battery charger capability criteria 2/25/84 C-132 Undervoltage relay setpoints I/8/84 C-134 U-l to U-2 interlock to LOP sequencer 2/24/84 C-135 DG lockout of incoming 4-kV breaker I/8/84 Draft engineering evaluations covering diesel generator local operation and instrumentation have been completed, and those for DG electrica! loads sequenc-ing and shedding have been modified to include the power distribution system.

The technical review of the DG and PDS electrical characteristics and protec-tive devices / settings is in progress, as is the review of the PDS cable sizing / routing / separation. The technical review of the 120 Vac and 125 Vdc power systems is progressing, and awaiting receipt of additional requested information.

Internal review of the draft engineering evaluations is continuing, and engi-neering evaluations are being updated to reflect OCR dispositioning.

Although the primary emphasis in the civil / structural review areas for the SEP system was on disposition of OCRs, efforts continued in the preparation of engineering evaluations. As of the end of February, reviews had been initiated in all civil / structural review areas for SEP. Progress on OCRs continued as additional information was received. This information was reviewed in antici-pation of the March I meeting on civil / structural OCRs.

2.2.4 Control Room HVAC System Progress The documentation of er.gineering evaluations is continuing, with the completion of all major system performance topics scheduled for March. To facilitate completion, the major effort has been cirected to final dispositioning of

, outstanding OCRs. Based on information received and reviewed during the week of February 27, 1984, in conjunction with the OCR meeting, there are three of the 21 OCRs which require additional review efforts. The other 18 have been or will be dispositioned by the first week of March. Of the current OCRs remaining, sufficient documentation has been assembled to coafirm or resolve two in early March. OCR 3201-008-085 requires a more extensive evaluation, which has been initiated. This OCR addresses on itern which need not be dispositioned to issue the report covering performance topics. The system l

performance report was initiated in late February.

The status of the structural review of the Auxiliary Building, which houses the

! HVAC system components, is discussed in Section 2.2.2 of this report.

2.3 Construction Verification Activities 4

During this reporting period, ICV reviewers continued to status existing Confirmed items and Findings. These activities included the review and evaluation of responses received from Bechtel and CPC, in addition to meetings held for the purpose of acquiring supplemental information and the clarification i of concerns expressed by the OCR or Finding. Principal activities were as

follows

e Meetings were held with cognizant Midland site personnel on Wednesday and Thursday, February 22 and 23,1984. The initial intent of the site visit was to witness the disassembly, refurbishment, and reassembly of the AFW pumps as a follow-up activity to Resolved Finding Z-046, which concerned itself with storage and maintenance activities on the pumps. This activity, however, was 1

postponed until early summer. While at the site, the following was accomplished:

4 l

e ,

- Discussions were held with CPC MPOAD personnel responsible for the control and conduct of the Quality Verification Program (GVP). The intent of the discussions was to solicit information concerning the organizations, key individuals, and the procedures and plans which will play on important role in OVP execution. As a result of the discussions, CPC committed to forwarding the Quality Verification Program Document and applicable procedures. These documents were subsequently received by TERA with CPC's letter of March 6,1984. ICV reviewers have commenced their initial review of the procedures and plan.

Discussions were held with Bechtel personnel responsible for j site storage and maintenance activities. The purpose of the l meeting was to status the approval of the revised site storage and maintenance procedure. TERA's review of the procedure is instrumental to the disposition of Finding F-047. As of the meeting, procedure FPG 5.000 had not been approved for imple-l mentation.

Other activities undertaken at the site related to the review and verification of selected documentation referenced by Bechtel and CPC in their responses to Findings F-056, Material Selection; F-047, Storage and M,ointenance; and F-052, Vendor l Documentation Submittals.

e During the reporting period, TERA received responses from Bechtel and CPC addressing the following Confirmed items / Findings. TERA reviewers are in the final process of establishing a final disposition based upon the responses or have initiated requests for additional

, information necessary to clarify the response.

F-047: Storage and Maintenance F-052: Vendor Documentation Submittals F-091: Lesson Plan for Training of GC Inspectors 5

F-092: Qualification Program for OC Inspectors C-093 thru C-096: CR-HVAC System Documentation and Physical Verification 3.0

SUMMARY

OF CONFIRMED AND RESOLVED ITEM REPORTS, FINDINGS REPORTS, AND FINDING RESOLUTION REPORTS Attachment 2 provides TERA's Tracking System Summary for Open, Confirmed, and Resolved (OCR) Item Reports, Finding Reports, and Finding Resolution Reports. This tool assists TERA in tracking the disposition of issues as they progress through the review process. Items that have changed status or that have been added during the reporting period are noted with an asterisk.

Attachment 3 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 paragraphs discuss items which have changed status in the post month.

During February, a new Finding and two new Confirmed items were identified.

A previous Finding, four previous Open items and twelve previous Confirmed items were resolved. Additionally, three Observations were identified. No open items were identified. Accordingly, the status of disposition of OCRs/ Findings for the IDCVP from inception through March 16, 1984, con be summarized as follows:

OCR/ FINDING Identified Active Potential Oper. Items lS9 0 Open items 136 12 Confirmed items 99 47 Findings 21 12 Resolved items S3 Finding Resolution 9 Observations 26 Finding F-0IS is concerned with odditional seismic response amplification ; hat is associated with the flexibility of floors in the auxiliary building. The effect of floor flexibility was intentionally omitted from the design analyses using a 6

Bechtel study as a basis. TERA hos reviewed this study as well as one performed l

by SMA as part of their Seismic Margins Evaluation of the Midland plant. On the basis of these studies, it has been concluded that the predicted seismic response l Is higher than specified by the project for input into the design of components / piping.

• Finding Resolution Report Z-043 provides close-out for an item that is concerned with the classification of a piping line os " hanger critical." Lines classified as such receive prescribed inspections even though non-Q. For the case in question, the project clarified on apparent conflict between a statement in spec M-480 where the line was not identified as hanger critical and statements made by project personnel indicating that it was. Another document, o P-129 form is considered controlling as codified by a change to spec M-327. Based upon this change, the Finding was resolved.

Confirmed item C-156 is concerned with the design of embedded channels and plates to which piping and miscellaneous components are ottoched. A specific situation has been identified where design criteria may not be met.

Confirmed item C-157 identifies on error in the transfer of a mass moment of inertia to the center of gravity of the auxiliary building foundation. The calculation in question was completed in response to another Confirmed item C-104.

5 TRUCTURE(5), SYSTEM 5(5), OR COMPONENT (S) INVOLVED: 1 Au(111ary Building, AFW & CR-HVAC Systeas & Components DESCRIPTION OF FIPOING: The referenced Bechtel and SMA studies (1,2) indicate that seismic response is amplified (as high as 5 times at certain frequencies) when floor flexibility is analytically considered. The Bechtel study (1) has evaluated the potential impact to equipment and concludes in (3) that floor flexibility need not be considered; however, TERA has concluded that this study has not provided sufficient technical justification. The SMA Study (2) has evaluated the seismic capability of equipment / piping utilizing somewhat differerit criteria than the FSAR in an attempt to realistically quantify the margins of the Midland plant to withstand a hypothetically larger earthquake than the SSE. This study has generally demonstrated that significant margins exist; however, the study is not focused at determining margins relative to SIGNIFICANCE OF FINDING: that associated with FSAR commitments. Accordingly, informa-tion is not currently available which would verify that the FSAR " package" of criteria are met when floor flexibiltty is considered.

The functionability of certain equipment and piping located on flexible floors may be compromised under a seismic event and FSAR criteria / commitments may not be met.

RECOMMENDATION:

Select a sample of representative equipment / piping located on flexf ble floors and i compare the seismic qualification test / evaluated spectra to the required response spectra, appropriately amplified for floor flexibility effects.. Determine whether or not FSAR criteria are met and more generally, the seismic capability utilizing the SMA studies as appropriate. .

Bechtel field change requests f16694, t16309, and 116995 refer to down-rating the design pressure of certain high-pressure drain piping associated with the turbine and inlet valves of the AFW steam-driven pump. The stated reason is to facilitate testing, since these high-pressure lines are connected to lower pressure lines from which isolation cannot be provided for testing. There is no indication that an engincering evaluation was performed to justify the change.

ATTACHtiENT TO 3201-008-2-043 DESCRIPTION OF RESOLUTION: Bechtel performs inspections of seisn$~ c , but non-Q, piping in accordance with its M-327 document. Such piping is called " hanger cr1tical" and may be so classed for a number of reasons, including seismic

~

I 4/I. Since only " hanger critical" piping receives certain inspections (see Section 6.0 of M-327), it is important to know which hangers are in this category.

Bechtel's M-480 document contains a column which is used to indicate whether the piping is subject to the hanger inspection.

For 10"-2HBD-605 the entry on M-480 is "N " indicating that this piping is not hanger critical, although project personnel had indicated thet it was. A Bechtel letter dated January 8,1984, provides clarification of this situation.

Although M-480 provides information concerning whether piping is considered hanger critical, the Bechtel P-129 document is considered controlling. This fact is noted in M-327, as clarified by the application of SCN-19 to Rev.10 of H-327.

This Finding was resolved by reviewing 11-327, SCN-19, and M-480. Furthermore, the P-129 form applicable to this piping was compared against H633, sh 3, Rev.10 and found to be consistent. Based upon the change to M-327 which specifies that the P-129 form is controlling, this Finding is considered resolved.

Calculation package DQ 59.1 (Q) " Finite Element Review for FSAR i.oad Combinations" for the Aux. Bldg. underpinning model analysis, references BSAP run file TIEN OBQ, as input to the calculation. However, this file may have been superseded, by TIEN OJY or TIEN ORA files. In addition, file TIEN OBQ could not be located for review by TERA.

slGNIFICANCE OF CONCERN:

Superseded, or incorrect, infomation could affect design. Requirements of the Aux.

DESCRIPTION OF CONCERN: The CR-HVAC P&lD (M-465) shows that the control room makeup l air dampers are arranged in series as OMO-6501 A and -6502A in Train A and -6501B and

-65028 in Train B. This arrangement results in the in-series dampers being powered I

from Group i and Group 11 power (plant single-line drawing E-1 and schematic diagram E-456). The group power can be lined up to eithe- Unit I or Unit 2 and is controlled by Kirk-Key interlocks. The concern is that a single failure in Group i or ll would prevent the availability of makeup air three hours af ter a hazardous chemical or high radiation event coincident with unavailability of Unit I standby power or an uninhabi-table atmosphere outside the control room.

SIGNFICANCE OF CONCERN:

Positive control room pressure may be lost three hours after initiation of the event which may result in the control room becoming uninhabitable. This would violate GDC 19.

RESOLUTION: The air dampers are physically located in rooms 733 dnd 734, whjch are in reasonably close proximity to the Control Room. Manual reposi-ti)ning is an acceptable alternative, provided certain conditions are satisfied.

(See Standard Review Plan -- NUREG-0800 Rev. 2 Section 6.4, Appendix A.) It has been confirmed that the design includes local manual override capability, and the internals are of a type considered to be highly reliable (see vendor I print M-154-3-7). The personnel exposure for the crew utilized to manually operate the valve would also be acceptable based on calculations of post-LOCA dose rates in the Auxiliary Building (see FSAR Table 12.3-7), particularly after three hours into the event.

Based on a review against the criteria of NUREG-0800, manual actuation is considered an acceptable alternative to a design for single failure.

1. Bechtel's answer is satisfactory. The only areas where the approximation is critical are for the underpinning and the EPA where the local mass moment of inertia may be underestimated by up to 40 percent. However, when the local mass moment of inertia is transferred to the base to obtain ghe mass moment of inertia with respect to the center of rocking the term mh (correctly calculated) is governing and the total error is less than 1 percent.

('however, bnly one can be running at a time (Ref. J-232, Sh 1,' Rev 5) .

J This is a discrepancy of 900hp.

3. OPE-1 appears to have based the load of 2VH-54A on 1.5hp rather than 3.0hp.

4. OPE-1 is inconsistent in the application of its own assumption 4, "... manually started loads are assumed operating." Examples include:

2VV-57B & D Rx Bldg Cooler Fans Assumed On Low Speed 2VE-54B Hydrogen Recombiner OVE-04B Fuel Handling Electric Coil OP-76B Fuel Cooling Pump OVV-86B Fuel Area Exhaust Fan

5. OPE-1 appears to underestimate the load for ?"-232B (Service

^

6. OPE-1 bases the load for OVV-86B (Emergency Fuel Area Exhaust Fan) on 50hp instead of 75hp as identified on E-18, sh 17, Rev.12.

7. OPE-1 assumes 15kW for Battery Charger 2D25 instead of 74kVA as indicated on E-18, sh 11, Rev. 15.

8. OPE-1 does not account for both Ovv-90D & E (Service Water Supply Air Fans) nor both OF-75D & E (Service Water Strainers).

9. QPE-1 assumes no load on instrument transformer OX95, while E-18, sh 21, Rev.10, ' indicates 25kVA.

10. "QPE-1 identified 155kN for motor operated valves and dampe rs. While the alternate calculation was relatively consistent (ie. 162.5kW), QPE-1 does not specifically

SEPTSystem - Class IE battery charger DCY PROGRAM AREA OR TASK (IF APPLICAPLE):

Topic 1.24-2 Electrical Load Capacity - DC l DESCRIPTION OF CONCERN: The following apparently inconsistent statements are made in the FSAR relative to battery charger capability: l (1) Can recharge battery while carrying largest combined demand of the various steady-state and transient loads irrespective of the status of the plant.

(2) Capable of carrying the respective normal steady-state and post-accident 125VDC loads.

(3) Can recharge battery while supplying the maximum demand of the steady-state loads.

Therefore the criteria and commitments for the battery chargers are unclear and conflicting.

SIGNIFICANCE OF CONCERN:

The suitability of chargers depends on defined load requirements. If the criteria which the battery chargers have to meet are unclear or conflicting, then the equip-ment may not satisfy its intended function, i

RECOMMENDATION OR RESOLUTION X  :

Bechtel letter dated 1/25/84 (Serial #140750) concurred that the FSAR statements were inconsistent and stated that SCN 4162 was initiated to correct the inconsistencies and be consistent with the project comitment to Reg. Guida 1.L (Rev. 2). SCN 4162 was received in preliminary form at the 2/29/84 status meeting. This SCN shows the con-sistent rewoniing to reflect the " normal and post-accident steady state loads".

Therefore this OCR is consi~ cered resolved. .

RECOMMENDATION OR RESOLUTION X  :

Reference 3 provides clarification indicating that C-501 is subject to certain limitations, particularly with regard to tie supplementation of design criteria developed in the remedial actions (ref. 4). Accordingly, references 1 and 4 together cover the full set of FSAR load combinations and items 1 through 3 are resolved.

Description of Concern Reference 1 lists concentrations for various chemicals in Appendix) at which isolation should be initiated (within 4 seconds), given a sudden irscrease from zero to the stated concentration. Reference 2 requires that the control room HV 4 isolation dampers (0610 6501 A & B and OMO 6502 A & B) isolate in 3 seconds. This means that af ter detecting the sudden increase in hazardous gas, isolation occurs 7 seconds after reaching the concentrations listed in Appendix A. Reference 3 determines the required sensitivity for hazardous gas detection for 5 second and 7 second isolation times.

The 7 second values for required sensitivity should, therefore, be specified; but some of the values correspond more close!y to the 5 second values. Bromire and hydrogen bromide are additionally allowed in the specification to respond in 16 seconds and 5 seconds, respectively, without adjustment to the required sensitivity. (See Note 1 in Appendix A - Ref.1)

Two of the chemicals, sulfer trioxide and ethylene oxide, listed in the calculation (Ref. 3) are not included in Appendix A (Ref.1). They are included in Appendix D. Table 1 (Ref.1). This table lists gases which are sampled less frequently because they are a lower priority. The basis for establishing these in the second level of testing priority is not identified.

A third level of sampling is provided in Table 2 of Appendix D (Ref.1). In the description to the table, a statement is made that the isolation dampers close in 2 seconds. The specification (Ref. 2) calls for 3 seconds.

On page 10 of Ref.1, paragraph 6.1.2(b), reference is made to Appendix A.

It appears this should be Appendix D.

The concern raised by the review of the specifications is that the specifica-tions are not consistent with the calculation and may result in unacceptably high toxic gas concentrations inside the control room.

1 l

I k,

h ATTACHNENT 2 TO 3201-008-R-129 j

i .

, RESOLUTION: The concern raised was primarily a question of whetdr the dampers specified for Control Room HVAC isolation closed quickly enough. ; Dampers

Ot10 6501 and OMO 6502 isolate in three seconds, which is not sufficiently l fast; however, in a normal alignment of the system, the flow is through a mdkeup HEPA filter bypass line. That path has dampers (0XV 6511 and OXV 6512) which are designed to isolate in one second. This has been confirmed by a review of vendor print 11-154-13-2 sheet 2 of 2; therefore, HVAC system isolation is considered to be sufficiently quick to meet system requirements.

A second issue identified in the OCR is the response time for bromine and hydrogen bromide. The monitoring system specification allows a slower response time for these substances. This apparent inconsistency is a result of the interface between the vendor and the designer. The technology for this device is state-of-the-art, which necessitates the setting of designer objectives instead of firm mouirements. Similarly, sulfur trioxide and ethylene oxide detection requirements are under development and are part of the issue addressed in OCR 3201-006-062.

SIGNIFICANCE OF CONCERN:

Load shed sequence may inadvertently initiate during bus transfer from station aux. transformer te startup transformer, since the ESF undervoltage relay set-points are specified at 60% instantaneously instead of 59% with a 0.7 second tiiae driay.

RECOMMENDATION OR RESOLUTlON X  :

The design documentation and design implementation, as indicated in Bechtel letter dated 1/8/84 (Serial #142207), now correspond and satisfy design criteria. The load shed setpoint and time delay are consistent with the FSAR.

Several loadgascswerechosenforevaluation.Forexample,acasecorrespondingtoaforce Fx=10 and moment Mz =50 k-in was chosen and stresses were computed and compared to the allowable stresses as specified in the acceptance criteria. The Factor of Safety was determined to be less than 1.0.

J SIGNIFICANCE OF CONCERN:

When c'asigned in conformance to the referenced drawing, attachments to the embedded ,

channels may not meet the design criteria.

III.1-1 Seismic Design / Input to Equipment DESCRIPTION OF CONCERN:

Inresponse to C-104, Reference 2 indicated that Bechtel was aware of the identified discrepancies and that they were addressed in Reference 3.

SQ-148K(Q) (Reference 3) page 9; the mass moment of inertia is incorrectly transferred tothe center of gravity in cases (b) and (c).

SIGNIFICANCE OF CONCERN:

Even though the mass moment of inertia of mudmat (E-W earthquakes) is underestimated by a factor of = 3.7, the overall impact is insignificant.

The concern is directed at the checking procedure that leaves such errors undetected.

DCV PROGRAM AREA OR Y ASK (IF APPLtCABLEh I.10-1 System Hydraulic Design DESCRIPTION OF CONCERN:

The ratio of the pressures across flow orifice 2F0-39002D is limited by the critical pressure ratio. The fluid flowing across the orifice then produces a shock reducing the pressure further downstream. Thus, a section of the downstream portion of the pipe

• sees" a higher pressure than shown on 11-480.

SiONIFICANCE OF CONCERN:

This is not a significant concern for the piping in question because its original design pressure wa higher than the pressure calculated using the critical pressure ratio. However, other situatinas may exist in systems othEr than~those reviewed

~

by the IDCVP 'where failure to consider the effect of the critical pr essure ratio may result in unconservative pressures being used for design.
