VERIFICAT;ON PROGRAM (IDCV)

MONTHLY STATUS REPORT NUMBER 8 PERIOD DECEMBER 1,1983 TiflOUGH DECEMBER 31,1983

1.0 INTRODUCTION

AND PURPOSE Monthly Status Reports have been instituted by agreement among 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 informo-tion relative to program progress and any impor: ant issues identified during the reporting period. This report coyers the period from December 1,1983 through December 31, 1983. A description of the scope, reporting periods and report issuance dates for Monthly Status Reports, as well as c summary of the background of the IDCV program, were presented in the initial Monthly Status Report dated May 27,1983.

2.0 IDCV PROGRAMi 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 reperting period con be found in the previous monthly status reports.

l The fif th OCR status meeting, originally planned for the end of December, was rescheduhd to January 4 to c foid conflict with the holidays. Programmatic l activities to be discussed at that meeting include clarification of the fact that the clock for the "10 doy" objective for responses to confirmed items starts with the OCR meeting where the item is first discussed. The "10 day clock" is used in determ ning when a confirmed item may be converted into o finding. It will also be noted that written responses are not needed for confirmed items but are B-84-07 i TERA CORPORATION

e i required for findings. Other items regarding status of OCRS and notification of revision of calculations will also be discussed.

By letter dated December 27 the NRC advised TERA of the acceptability of Law Engineering Testing Company to perform portions of the construction verifico-tion program. The NRC also formally accepted Revision 3 of the TERA Engineering Program Plan and Revision 4 of the PGAP for the Midland IDCVP.

During December TERA developed a structural engineering evoluotion of the diesel-generator building (DGB). Because of the timeliness of the issues involved, the engineering evoluotion was prepared in a format for public release.

This is on exception of the general IDCVP procedure of issuing only final reports and using the OCR process to identify matters requiring further reviews. In December review team members met in Ann Arbor to review DGB finite element and seismic stick models. The DGB engineering evoluotion is scheduled for release on January 4.

As noted in lost month's :.totus report, consideration is being given to o possible mid-course correction of the IDCVP. TERA project and management personnel have identified alternatives for making oppropriate corrections to the progtom.

Discussions among CPC, NRC, and TERA are contemplated but none is sched-

[ uled. TERA's near term priorities have been established so os not to foreclose

, desirable. refinements to the IDCVP.

I 2.2 DESIGN VERIFICATION ACTIVITIES 2.2.1

SUMMARY

l The most significaat activity in December was the completion of the engineering l evoluotion for the diesel-generator building. This evoluotion is scheduled for release on January 4.

Progress continued in all other arcos of the design verification review. Emphasi-was placed on completion of work previously initiated and dispositioning of OCRs.

2.2.2 AUXILIARY FEEDWATER SYSTEM PROGRESS In December the AFW system review continued, as it has in November, by concentrating on the disposition of OCRs and completien of supporting engineer-ing evoluotions. Lower priority is being given to completion of other engineering evaluations. No new engineering evaluations were initiated in December.

Review of auxiliary building structural topics continued but was slowed due to personnel being assigned to the engineering evaluation for the diesel-generator building. Specific subjects where progress was made in the civil / structural area included reviews of the SMA report, channel insert design criteria and support design, and foundation design for the auxiliary building.

Completion of engineering evaluations continued as previously requested infor-motion was received and evaluated. In the electrical and mechanical review areas verification of engineering evoluotions continued.

! An integrated engineering evaluation plan is being developed. This plan provides a correlation between the review matrix in the Engineering Program Plan and l

the related engineering evoluotions. The integrated plan eliminates redundant l effort in completing engineering evaluations and aids in the identification of l oreas requiring additional review to allow appropriate conclusions to be drawn.

l 2.2.3 STANDBY ELECTRIC POWER SYSTEM PROGRESS The technical review of the electrical load capacity, sequencing, and shedding of the diesel generator has been completed. The results of on independent load tabulation of the diesel generator (DG) loads has been compared to the DC design rating and to tha current Bechtel DG load calculation. The DG interlocks and permissives, as well as sequencer and load shed logic, were included in the l

B-84-07 3 TERA CORPORATION

,. 1 review. In particular, the primary undervoltage setpoint and the lood sequencer timer occuracy were examined. The review of the power distribution system (PDS) is in progress. The draft engineering evaluation for these DG ond PDS topics is scheduled for completion in January.

The evaluation of DG local operation, system interlocks, instrumentation, control systems, and actuation systems is also nearing completion, with certain aspects such as the system interlocks and ESFAS interface already completed.

Some of the detailed items being, reviewed include the DG pneumatic control system operability requirements and the storting air quality, as well as the 60-second coastdown interlock. The aroft engineering evaluation is also scheduled for completion in January.

The draft engineering evoluotion of the fire protection associated with the diesel generators has been completed. Diesel-generator building (DGB) wall penetra-tions and seal details were reviewed, along with fire detection system operabil-ity. Fire protection system features were examined in light of NFPA require-ments. The operation of the CO2 system was reviewed, including CO2 room flooding capability. Room pressurization and the associated Bechtel calculations v;ere also reviewed.

i The DG comber, tion air supply and engine exhaust draf t engineering evaluation has been completed. Intoke and exhaust as-built configurations were reviewed

! against vendor interface requirements and Bechtel design calculations. An alternate calculation of exhaust backpressure was performed due to variances in input parameters used in the design calculation.

The technical reviews of the DG and DC System Technical Specifications and the mechanical aspects of the underground fuel oil storage tanks were completed, and draft engineering evaluations are scheduled for completion in early January.

The fuel oil tank review included the effects of flooding. The draft engineering evaluation of the SEP system consolidated criteria and commitments is also l scheduled for completion in January. The review of the 125 VDC system is in progress and is scheduled to be completed in January.

, 1 The review of the DGB as-built condition has been completed with the assistance 1pf Professors N <le J. Holley (MIT) and William J. Hall (University of lilinois).

The IDV reviewers met as a teom in Bethesde on December 16, 28, and 29 to consolidate their review process and finalize their draft report.

Review of the DGB concrete / steel design (Topic .111.7-2) and foundation design (Topic 111.6-2) was pursued - by reviewing calculations related to the finite element analysis which is used to verify the adequacy of the design.

The engineering evaluation was completed at the end of December and the report was scheduled to be released on January 4. The engineering evaluation's primary conclusion is that the existing cracks, generally being of small size, are not indicative of a condition that would compromise the capability of the DGB in meeting its intended performance requirements. The IDV team also concluded that significant future cracking is not anticipated and the DGB is expected to remain serviceable without further remedial action. Rec.ommendations concern-ing CPC's commitments to verify continued serviceability are also provided.

2.2.4 CONTROL ROOM HVAC SYSTEM PROGRESS The responses to confirmed items provided in the November 11, 1983 Bechtel letter have been reviewed and the associated OCRs are resolved.

The 20 review topics which cover the control room HVAC System Performance

Requirements review area have progressed to a near completion status. For the sample initially selected

o Criteria and commitments have been reviewed and con-solidated from the FSAR.

l l o P&lDs have been reviewed.

o Design basis combinations of events and natural phenom-ena have been tabulated and reviewed.

l o Layout drawings have been reviewed for mechanical con-siderations.

o Calculations have been reviewed, o Specifications have been reviewed for functional require-ments and compliance to codes and standcrds commit-ments.

Engineering evoluotions are in preparation, leaving three areas to close -- OCRs, document revisions, and ossessment of the sample. Structural review of the ducts and duct supports is continuing. The status of structural review of the Auxiliary Building is discussed in Section 2.2.2 of this status report.

2.3 CONSTRUCTION VERIFICATION ACTIVITIES 2.3.1

SUMMARY

Activities undertaken and events which occurred during this reporting period which are important to the overall conduct of the construction verificaticn review portion of the IDCV program are os follows:

o The review of vendor and project NDE procedures was completed and the results of the review doc'amented on checklists. - A commary of observations extracted from the checklists has been prepared and included in Open items, OCR numbers 0-123 and 0-124. Further review is in progress to determine whether these items should be confirmed.

o Activities of ICV reviewers during this reporting period t

were focused .;pon the dispositioning of existing OCRs and Findings. Extending the ICV reviews into new areas has been held pending completion of selected CCP Phase I octivities. Recommencement of the Construction / Install-l

- otion Documentation and Physical Verification Reviews is onticipated in September 1984.

- Makeup Aic Temp = 96g FDB no references 79 FWB SIGNIFICANCE OF CONCERN:

Although the data appears reasonable, it is necessary to trace the data to a For example, controlled source in order to check the basis for the values used.

the makeup air conditions appear to be close to a 1% design basis from the ASHRAE Guide. This should be confirned and the reason for using 1% conditions stated.

Review Topic I.2-3 Accident Analysis Considerations Calculations Review DESCRIPTION OF CONCERN:

FSAR Section 6.4.2.3 states, "The toxic gas protection analy7,is, however, assumes a conservative inleakage of 82 cfm." The plant conditions under which this inleakage might occur are not identified. A review of calculations which address the toxic gas protection has been conducted atid these calculations do not include an analysis of an 82 cfm inleakage. The concern is that under some plant conditions, significant inleakage is feasible and the toxic effects have not been addressed in an analysis.

SIGNIFICANCE OF CONCERN:

Control room habitability could potentially be jeopardized.

i l

RECOMMENDATION OR RESOLUTION X  :

This item is resolved by classification as an Observation. The statements made in the FSAR are outdated. Inleakage is taken to be zero, as indicated in the resolution of OCR 3201-008-075. There are no adverse technical consequences, but the FSAR should be updated.

Topic I.9-3 Component Functional Requirements DESCRIPTION OF CONCERN:

Sheet 14 of the referenced calculation states as a conclusion, " Change fan motor from 30 H.P. to 40 H.P." The referenced specification includes the higher system total pressure of 5.5 in w.g., which led to the above statement, but the motor H.P.

is still 30. The concern is whether adequate driver H.P. is specified to meet flow requirements.

SIGNIFICANCE OF CONCERN:

! If motor H.P. were inadequate, the design basis flow could not be obtained; however, l a simple calculation of fan power performed by the reviewer indicates 30 H.P. is adequate. The Bechtel calculation was just conservative in its conclusion.

RECOMMENDATION OR RESOLUTION X This item is resolved by classification as an observation based on the fact that the l design requirement was adequately addressed.

Topic I.35-3 Ventilation - Calculation Review DESCRIPTION OF CONCERN:

The balance of the system requires that the static pressure drop in the return air duct exceed that in the fresh air duct by 4" WG to pressurize the control room. The values calculated are 0.82" WG and 0.62" WG respectively. To be conservative, the fan sizing should have been based on (0.62 + .25) instead of 0.82.

l 5IGNIFICANCE OF CONCERN:

Although the method was slightly in error, the consequences are not significant, because 0.05" WG is within the accuracy of the calculation. When the actual system is balanced, it will be important to understand the flaw in the method, to ensure that the correct cont.rol room pressurization is established.

3201-008-C-129 ATTACHMENT TO OCR ITEM REPORT:

Description of Concern Reference 1 lists concentrations for various chemicals in Appendix A at which isolation should be initiated (within 4 seconds), given a sudden increase from

zero to the stated concentration. Reference 2 requires that the control room

.HVAC isolation dampers (OMO 6501 A & B and OMO 6502 A & B) isolate in 3 seconds. This means that after detecting ti.e 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 oetecticn 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 closely to the 5 second values. Bromine 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 i 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 rot consistent with the calculation and may result in unacceptably l

l high toxic gas concentrations inside the control room.

III.6-2 Structural: Foundations III.7-2 Structural: Concrete / Steel Design DESCRIPTION OF CONCERN:

In the evaluation of foundation footing strips of the north-south walls, the conclu-sion of the insignificance of the moments about vertical axis is based on method of analysis (i.e., check of no sliding of foundation) which may not be appropriate.

The elastic deformation of footing strip and soil without relative sliding is ignored.

SIGNIFICANCE OF CONCERN:

High moments about the vertical axis in the north-south wall footing strips as obtained in the finite element analysis may not be as unrealistic as claimed in the ,

referenced calculation. Therefore, the evaluation of these footings may be non-conservative and may underestimate the stresses.

DCV PROGRAM AREA OR TASK (IF APPLICABLE):

Topic I.26 4.16KV Loaa Shed DESCRIPTION OF CONCERN:

Drawings J-878, Sh-1, Rev. 3 (4.16KV Load Shed Logic Diagram) and E-75, Sh-4, Rev. 6 (4.16KV Load Shed Schematic Diagram) do not reflect the primary undervoltage setpoint specified in FSAR Table 2.3-2, Sh-2, Rev. 47.

SIGNIFICANCE OF CONCERN:

Load shed sequence may inadvertently initiate during bus transfer from station aux.

transformer to startup transformer, since the ESF undervoltage relay setpoints are specified at 60% instantar.eously instead of 59% with a 0.7 second time delay.

Topic I.19-2 DG Control System (Pneumatic)

DESCRIPTION OF CONCERN:

The DG pneumatic control system is supplied air from the starting air system. The DG starting air compressors are on a non-class IE bus and are load shed upon loss of offsite power. Neither section 5.1.6 (starting air system) nor section 5.2.3 (control i systems) of material requisition M-18(Q), Rev. 9, specify control system operability requirements.

l $IGNIFICANCE OF CONCERN: ,

l Potential loss of both DGs due to loss of air subsequent to load shed. At 45 PSI of air, the low lube oil trip switches (2 out of 3 required) will operate and trip generator breaker and lock it out.

Topic I.7 System Interlocks DESCRIPTION CF CONCERN:

Diesel generator lockout blocks closure of ESF 4KV offsite incoming breaker. This design appears to be inconsistent with IEEE 308-1974.

SIGNIFICANCE OF CONCERN:

Engine malfunctions can block the restoration of offsite power even though no faults occurred on the associated bus. Thus, the preferred power supply is prevented from powering the ESF bus if it is available after engine malfunction lockout, i

Automatic controls do not select the most suitable power supply.

Process per PQAP.
