MONT14.Y STATUS REPORT NUMBER 6 PERIOD OCTOBER I,1983 THROUGH OCTOBER 31,1983
1.0 INTRODUCTION
AND PURPOSE Monthly Status Reports have been instituted by agreement between the Consumers Power Company (CPC), the Nuclear Regulatory Commission (NRC) and TERA to provide porties 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 October I, 1983 through October 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 PROGRAM STATUS
SUMMARY
I 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 worront special highlight.
The third OCR status review meeting was held on October 28,1983 of Bechtel's l Ann Arbor, Michigan offices. In addition to the statusing of oustanding issues, the discussions promoted on understanding and any clarification necessary related to new issues so that CPC or Bechtel could either identify information that may not here been available to the IDCVP review team or clarify I
Information that was available and reviewed. Minutes documenting discussions of this meeting and commitments made were issued on November I,1983. The fourth OCR status review meeting will be held on December I,1983, rather than during the lost week of November, to avoid a conflict with the Thanksgiving holiday.
Ford Amendment activities took place during the reporting period. Represento-tives of the NRC l&E Headquarters Staff observed TERA octivities during the week of October 24,1983 at the Midland site and at Bechtel's Ann Arbor offices.
Physical verification activities were initiated during the reporting period for CR-HVAC components and commodities within the Zock scope of supply. These activities were able to be initiated because Zock work is outside the scope of the CCP program and not subject to o CCP limitation. This limitation is based upon a programmatic decision not to physically verify items until such a time that the CCP has possed through and completed its activities.
The review of several process oriented issues was initiated based upon the identification of specific items and observed trends within the iDCVP:
e FSAR omendment process e Field change process (FCR/FCN) e Storage and maintenance program o NSSS/ BOP interfoce e Electrical, instrumentation, and control calculation /engi-j neering evoluotion contro!
l 2.2 Design Verificotton Activities f
l t
2.2.1 Summary l
l Significont progress was made in the design verification program for oil three
! systems during October. Of particular note has been the extensive .:r:tivity in 2
)
i ,,
the structural review area for the AFW ond CR-HVAC systems. TERA personnel reviewing the civil / structural aspects of the design spent opproximately 25 man-days in Ann Arbor during October in order to review calculations and other documentation. Civil / structural review associated with the standby electric power system was initiated in October.
Members of the design verification team visited the site on October 26 to assess the physical configuration of system components, to interface the IDV and ICV octivities, and to enhance their understanding of the plant design features. This site visit was followed by dato collection meetings in Ann Arbor the next day and the Confirmed items meeting on October 28. During the meetings in Ann Arbor, representatives of the NRC attended discussions between TERA and Bechtei personnel as part of their " Ford Amendment" octivities.
The consolidated design criteria list for the standby electric power system was issued for internal review.
Activities which progressed significantly during October which offect all three systems include the review being mode of scopes of work assigned to service contractors and evoluotion of MCARs and SCREs for consideration in selecting
. oppropriate review sampies.
OCRs are discussed in more detail in Section 3.0 of this report.
2.2.2 Auxiliary Feedwater System Progress During October, work progressed towards preparing a draft interim topical report on the AFW system. The scope of this report includes the AFW system performance requirements review areas described in the Engineering Program P!cn (EPP) and as listed in Figure 1.2-20 of the EPP. Due to the existence of OCRs in these areas and associated work in progress, it was determined that the report connot provide final ccelusions on these review topics and therefore represents o detailed topical status report. At the October 28 OCR status review meeting the question of whether to complete the report and the form for i
l 3 l
. v the report (i.e. detailed status report or o conclusionary report) was left as c matter to be decided in November.
Progress in the review of the civil / structural aspects of the AFW design included the following:
e Further review of the piping analysis was made in prepo-ration for the planned revision of the confirmatory calcu-lotion planned for November.
o Progress on review of supports was sisved because of the need to obtain calculations from Grinnel. A proprietary information ogreement regarding these calculations is being pursued.
e Seismic equipment qualification review activities con-tinued, new information was received, and the engineering evoluotion for this topic was initiated.
o Work continued in the reviews of foundations, concrete and steel design, and other structural design-related topics.
e The review of Confirmed item C-015 at the October 28 meeting determined the need to review a study performed by SMA on the effects of floor flexibility on seismic vertical response.
In the mechanical and electrical review areas, odditional information was l
i received to assist in determining the disposition of open items.
On site reviews were conducted by AFW review team members as part of the site visit by the design review team.
l 2.2.3 Standby Electric Power System Progress l
The SEP system consolidated criteria and commitments document has been issued as Revision 0 and is being evicuoted for consistency, applicability, and completeness.
l 4
l
Specific information has been identified for each SEP system work package, and the corresponding document numbers have been obtained for many of the items during meetings with Bechtel personnel in Ann Arbor the last week of October.
Information requested included:
o Over 75 schematic, logic, P&lD, single line, layout, and detail drawings; e Eleven electrical and mechanical procurement specifico-tions; e Twelve Supplier Document Registers to identify pertinent vendor documentation; e Eleven additional electrical calculations; e Mechanical Calculation Indices to identfy specific oppli-cable calculations; e Buried Piping Analysis Topical Report.
Recent revisions to the following electrical calculations have been received and are being reviewed:
OPE-4 5 & 8 kV Cable Sizing QPE-5 125 Vdc Bottery and Charger Sizing QPE-7 inverter Sizing Engineering evaluations have been initiated in the following additional areas:
i Diesel Generator Cooling / Heating Requirements l
Fire Protection associated with the diesel generators
' Diesel Generator Building Flood Protection i Technical Specifications for DG and DC Systems i
i The remaining engineering evoluotions will commence subsequent to the receipt of the information required for each evaluation.
The review of the civil / structural aspects of the stand'oy electric power system was initiated in October. Specific emphasis has been placed on the structural 5
4 evoluotion of the diesel generator building and its capability to meet design basis requirements in its as-built condition. Professors Myle J. Holley (MIT) nnd William J. Hall (University of Illinois), member of IDCVP Senior Review Team, have been requested to assist in this review.
2.2 4 Control Room HVAC System Progress The engineering evoluciion for the criterio review of the fol.owing topics was completed.
e System operating limits e Accident analysis considerations e System pneumatic design e Cooling / heating requirements e Filtration e Pressurization e Ventilation This engineering evoluotion is undergoing internal review.
The outstanding FCRs for the system P&lD were received and reviewed, thus completing the P&lD review and documentation in the completed checklist.
Calculations for the above list of topics have been reviewed and that review is complete with three exceptions: 1) resolution of OCRs, 2) completion of dose i
calculation review, and 3) clarification of minor items on a static pressure l calculation.
The drawing review stage of the program was initiated in October with the receipt of HVAC duct layout drawings and standard details of the seismic HVAC ducts. These drawings are being reviewed for conformance to mechanical design l
os described by the P&lD and also for structural aspects for seismic considero-l tion. The seismic considerations are being handled in conjunction with the review of the standard calculation for duct qualification. Architectural drowings were reviewed for significant leak paths; however the details for the control room doors cre not identified on the door schedule and review will be on hold l
l 6 I' - - . .
i until such drawings are issued. The doors are the major leak path per existing 4
calculations. As part of the design review effort, a site walkdown of various aspects of the system was conducted to familiarize the reviewers with the overall physical aspects of the system. This was intended to facilitate the drowing review activity.
System olignment requirements relating to the single failure review were clarified in response to on OCR and the review of related electrical topics is proceeding. Logic diograms have undergone on initial review resulting in a request for additional diagrams, which were received. Further progress in this area is expected in November.
1 The structural review of the Auxiliary Building os discussed under the AFW review has beam extended to incorporate aspects of the seismic design pertinent to the Control Room HVAC. For a discussion of progress in the combined structural review, see the AFW System discussion.
2.3 Construction Verification Activities 2.3.l Summory Activities undertaken and events which occurred during this reporting period which are important to the overall conduct of the construction verification i
review portion of the IDCV program are as follows:
e Upon bringing the construction / installation documentation review of selected AFW system components to the level of completion allowed by the CCP, site activities were directed to reviewing construction /
installotion documentation of selected components and commodities i
within the CR-HVAC system. These activities were undertaken to progress the construction / installation documentation review and to assemble the documentation necessory as a precursor to conducting physical verification of selected CR-HVAC components and commod-ities within the Zock scope.

. e e ICV reviewers completed the preliminary engineering evoluotion of the pipe support reinspection program. The evoluotion is currentfy under review of IDCV program management.
e Reviews of process-related issues occupied a significant portion of ICV octivities during this reporting period. ICV reviewers focused their efforts upon processes implemented /pending implementation
! associated with site storage and maintenance and FCR/FCN design l I change control. These process reviews were identified as instru- i l
mental in addressing the resolution to Findings F-047, storage and I maintenance, and F-031, FCR/FCN relating to pipe hongers and l g
supports.
2.3.2 Construction Documentation Review Progress Construction documentation review reiotes to those ICV review categories which are principolly concerned with the adequacy and completeness of available documentation as opposed to those ICV review categories which verify the physical configuration of installed components and commodities. The following ICV review categories are part of construction documentation review.
e Review of Supplier Documentation e Review of Storage and Maintenance Documentation e Review of Construction / Installation Documentation l
l A description of progress mode and principal activities undertaken in each of the above review categories are os follows:
Review of Supplier Documentation e The review of vendor-supplied NDE procedures was completed during this reporting period. An evoluotion of the items obscrved during the j
review and recorded on checklists is currently being conducted. The 8
1
l l
review was conducted by LAW Engineering personnel with the evoluu-tion of the results being undertaken by both LAW and principal TERA personnel.
e Confirmation of inconsistencies noted as a result of the review of vendor-supplied documentation for selected components within the CR-HVAC and SEP systems continued during the month of October.
This task is made more difficult due to the complex manner of recording vendor-supplied documentation associated with components purchased as port of the Diesel Generator purchase order.
e inconsistencies noted as a result of a review of vendor-supplied material selection and verification documentation were evoluoted and determined to be Confirmed items os documented in C-056, see Attochment 3.
Review of Storage and Maintenance Documentation e As a result of the review of documentation submittols provided by Bechtel during the previous reporting period and a review of offected site storoge and maintenance procedures, TERA has initiated and completed Finding Resolution Reports Z-045 and Z-046, see Attach-ment 3.
e in reviewing site progress in reconciling specific inconsistencies noted in C-047 and in noting progress of site activities in implement-ing revisions to offected site storage and maintenance procedures, ICV reviewers noted the following:
- Site procedures noted in C-047 and currently governing site storoge and maintenance activities have rrt been revised.
9
1
- Site storage and maintenance personnel have per-formed those activities necessary to present to monogement a program plan and supporting proce-dures necessary to alter the existing site storoge and maintenance program. As of the writing of this report the principal implementing procedure, FPG 5.000, has not received approvo! for implemen-totion. Upon approval, ICV reviewers will continue their evoluotion of storage and maintenance pro-grum implementation.
Review of Construction / Installation Documentation e ICV reviewers conducted a detailed review of the construction /
Installation controlling documentation and documentation assembled to verify the quality of installed components and commodities within the CR-HVAC system sample boundaries. These activities were undertaken to verify the completeness and adequacy of the documen-tation ond to assemble that documentation necessary to conduct a thorough physical verification of the selected items. The review was completed during this reporting period with the results indicating that of the forty-two (42) items identified for current review within the CR-HVAC system sample boundaries, seven (7) items were considered as complete. The remaining thirty-five (35) items were considered incomplete due to GA holds, destatusing, or QA/QC Inspections statused as not complete.
e During the lost week in October, LAW Er.gineering personnel initiated a review of welding procedures and, proc edure and welder qualifica-tion records pertinent to the CR-HVAC system. This review and subsequent evoluotion are anticipated to be complete during the early part of November.
10
e Activities were initiated by IDCV program monogement to allow for the temporary cessation of construction / installation documentation review over the immediate near term. These actions were initiated principolly as a result of the recent stop-work orders and CCP status which, based upon TERA's observations, have caused a delay of site octivities on G-related systems specified to be within the IDCV
"- sample boundaries.
e inconsistencies observed as a result of the review of selected site welding procedures and procedure qualification records were evolu-ated during this reporting period. As a result of the evoluotion; items previously identified in Open item 0-055 have been statusted as a Confirmed item C-055, included in Attochment 3 to this report.
2.3.3 Physical Verification / Site Activities Program The activities described herein oddress those ICV review categories which require ICV reviewers to observe, witness, or verify field octivities and/or the as-built configuration of installed commodities and components. For the most part, these activities require o strong site presence on the part of reviewers and include the following review categories:
i e Review of Selected Verification Activities e Verification of Physical Configuration Review of Selected Verification Activities e ICV reviewers completed their evoluotion of the activities observed as port of the pipe support overinspection program. TERA completed a preliminary engineering evoluotion. As a result of the evoluotion, two programmatic inconsistencies were noted relating to the training program for inspectors and the manner with which GCEs are qualified to governing procedures. The inconsistencies observed as a result of II l
l
. o the evoluotion are noted and recorded in Confirmed items C-091 and 092, included in Attochment 3 to this report.
e As a result of reviewing documentation forwarded to TERA with Bechtel letter dated October 10,1983, and as a resu!t of discussions with cognizant Bechtel/CPC personnel during the OCR status review meeting on October 28,1983, ICV reviewers have prepared Finding Reports F-049 and 050, included in Attachment 3 to this report.
These OCRs, dealing with the cable overinspection program, were reported as confirmed items in the previous status report.
e A statistical model was prepared during this reporting period which could serve os o quantitative method in evoluoting ICV review results of selected reinspection programs. Utilization of the model is still under evoluotion by principol IDCV program personnel.
Verification of Physical Configuration e NRC representatives Messrs. Keshishion and Gower were at the TERA Midland site office on October 25 and 26,1983, to discuss and observe TERA octivities undertaken in preparation for the physical verification of selected CR-HVAC equipment and to observe tne results of activities undertaken in conducting the construction /
installation documentation review of selected AFW system compo-nents.
I e ICV reviewers conducted a walkdown of the CR-HVAC system in preparation for conducting a physical verification of installed com-ponents and commodities. As a result of the "walkdown" and status of completeness determined from the construction / installation docu-mentation review, seven (7) of the forty-two (42) items were statused as complete and eligible for the physico! verification review. Physi-col verification review activities were initiated with the completion l
l 12
J %-
i of the review of eligible items anticipated during the early part of
' m November.
e
~
TERA reviewers visited the site during the week of October 24,1983 \
to revie y the processes used to control field modifications to piping 3 and pipe support drawings. This activity is part of the recommendo-tion included in Finding Reports F-031 and F-036, and Finding Resolution Reports Z-032,' Z-033, Z-034, and Z-035. The site visit I coincided with the issuance of CPCO MPQAD Stop Work Orders FSW-33, FSW-34, FSW-35, FSW-36, FSW-37, FSW-39, FSW-40, and FSW-41, which cited problems with the referencing'of drov,ing and s i
specifications in the Bechtel Field Change Request / Field Change t Notice process. Since the FCR/FCN process is the primary proce- I U
dure for incorporating field changes, the visit focused on gaining on understanding of the current FCR/FCN problems. On-going efforts are oddressing:
- Verification of recovery from the stop work orders, and
- Assessment of cumulative effect of field changes on inputs and assumptions within design calculations.

SUMMARY
OF CONFIRMED AND RESOLVED ITEM REPORTS, FINDING 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 trocking the disposition of issues os they progress through the review process. Items that have changed status or that have been odded during the reporting period are noted with on osterisk.
Attochment 2 provides retyped copies of 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.
13
i Three Findings were identified during the reporting period. Finding F-018 is related to the committed design criteria for the decoy heat load. It was found that statements in the FSAR ore not internally consistent and not consistent with related calculations. The project has clarified its commitment indicating
' that the AFW system is sized based upon a B&W decoy heat curve and not Branch Technical Position APCSB 9-2 and ANS 5.l; however, o calculation has been i completed comparing the original results with APCSB 9-2. A SAR Change has been effected to correct noted inconsistencies. On the basis of this action and 4 review of a recent B&W calculation demonstrating proper AFW system sizing, I the item has subsequently been resolved through issuance of Finding Resolution
- Report Z-018. A related Observation, B-080 has been noted. Findings F-049
- ond F-050 each relate to issues identified during the ICV review of the cable -
s overmspection program. F-049 identified cables which foil to satisfy separation requirements in the air-lined region as these cables terminate into cabinets. The projact recognizes this discrepancy and has indicated that they are investigating ,
solutions such as wrapping or potentially gaining dispensation from the separa-t t
[
s tion requirement in this region. F-050 identified a cable that is routed outside
. of its scheduled via. The ICV reviewers ' hove determined that the engineering I s
' ' significance of this routing is minimal; hcwev[ e r, the criteria for dealing with such a routing cre not definitive within the cable overinspection program.
f 1 Finding Resolution Reports Z-04S and Z-046 hcve been issued. Both of these items relate to specific discrepancies noted in the storage and maintenance progrcms. Specific maintenance instructions have been revised to correct the identified discrepancies. TERA is currently reviewing actions taken by the l
project to generally improve the storage'and maintenance programs. This item is currently being trocked vio previous Finding F-047.
s Confirmed items C-020, C-027, and C-028 were resolved. These relate to apparent inconsistencies in the AFW system design criterio os documented in the FSAR and the BOP Criteria Document (B&W Report 36-100477, rev.1). Resolv-l tion was based upon clarification provided by the project including a SAR Change. Further related effort is being devoted to review of the FSAR omendment process and the NSSS/ BOP interface.

System Heat Removal Capability (1.11-1) System Hydraulic Design (I.10-1)
Component Functional Requirements (I.9-1)
DESCRIPTION OF CONCERN:
There are inconsistencies in inlet water temperatures used in AFW analyses. The B&W criteria * (section 2.14) require the use of 90 F inlet water temperature for AFW system design. B&W's " Specific Design Criteria for Safety Grade AFW Control System" document (4100) describes 90 F as " typical." BAW 1612, Rev.1 (section 2.1) makes use of a 100 F value in calculating minimum flow requirements. The FSAR contains analyses indicating a maximum service water temgertture of 105*E Bechtel calculation FH 4117-28 uses a maximum SW temperature of 108 F.
- Document #36-1004477, Rev. 1 SIGNFICANCE OF CONCERN:
Use of a 90 F temperature when 105 F can occur results in an underestimate of tha quantity of water required to remove the heat being generated in the primary sys.em.
This in turn affects the AFW system heat removal capability, its hydraulic design basis, and the sizing of components.
RECOMMENDATION OR RESOLUTION X B&W Calculation 86-1143885-00 and Bechtel letter BLC-18114 provide documentation that 105 F rather than 90 F results in only a minor primary temperature increase. The Bechtel letter states that "No further action . . . is required on this item." We agree that this specific issue is resolved, but velieve that the B&W B0P Criteria Document (Ref. 2) should be revised (see Observation 3201-008-B-080)

DESCRIPTION OF CONCERft The FSAR contains references to the following power levels: (a) 2452 MWt - license power level, (b) 2552 MWt - power level for calculation of core inventories for accident analyses, (c) 2603 MWt - power level for containment analysis.
The 2552 ."Wt power was used in the B&W AFW calculation (Ref.1). The 2603 MWt is 102% of 2552. FSAR page 10A-17 (Item a) states that 102% of maximum power level is used for AFW analysis. Thus, the power level for A91 analysis should be 2603 MWt.
SIGNFICANCE OF CONCERN:
If 2552 HWt was used, the heat load which must be removed by the AFW will be under-estimated compared to the heat load associated with operation at 2603 MWt, resulting in undersizing of AFW components. Furthermore, other analyses may need to be per-formed at 2603 MWt.
RECOMMENDATION OR RESO4 >JTION X :
Ref. 2 provides an SAR change notice which clarifies the reactor power level to be used for evaluating the AFW system. Thus, 2552 MWt will be used for evaluation of AFW.

(Review of Criteria and Comitments)
DESCRIPTION OF CONCERN:
The AFW system design may not megt a B&W interface requirement that auxiliary feed-water temperature be at least 40 F. B&W's BOP criteria for AFW (Ref.1) requires a 40 F minimum AFW temperature. This criterion is consistent with the B&W document for reactor coolant system analysis (Ref. 2) which is used in analysis of reactor coolant system components. Bechtel calculation FM-4117-28 (Ref. 3) uses a 32 F temperature as a worst case winter temperature.
SIGNFICANCE OF CONCERN:
If the interface requirement is not met, analyses of the reactor coolant system components could become invalid, l

Review Topic I.12-3, Cooling / Heating Requirements DE5CRipTION OF CONCERN: .
The calculation is intended to check the cooling coil load. In the assumptions for the calculation, the conditions for a post-LOCA are presumed to exist. No l statement is made regarding other accident conditions. The concern is whether other accidents would cause more limiting demands. For example, are adjacent wall temperatures higher during a steam or feedwater line break?
56CNFjCANCE OF CONCERN:
The cooling coil sizing appears marginal. If there are conditions which increase the load, a higher control room temperature would exist.
RECOMMENDATION OR RESOLUTION X Referencing the 10/28/83 OCR meeting, it was determined that the post-LOCA condition
^
is the nest limiting for cooling coil sizing. There are no postulated high energy line breaks in the vicinity of the control room which would result in increased cooling loads. The marginal sizing of the coil is being addressed in a revised calculation and is covered by OCR 3201-008-0 058.

DESCRIPTION OF CONCERre Bechtel letter BLC-18114 (Ref.1) provides the basis for resolving several OCRs including C-020, C-027, and C-028. No reference is made regarding revision of the B&W interface criteria document (Ref. 2). The B&W criteria document goes beyond interface criteria and, in fact, functions as a primary source of design providing(along criteria vith the FSAR). Minor inconsistencies exist among References 1 and 2 and the FSAR. bce attached list for examples.)
SIGNFICANCE OF CONCI RN:
This concern is of minor significance if the B&W interface document is eventually replaced with a final design criteria / basis document which serves as a point of reference for future design changes. With the present inconsistencies a risk of errors in future revisions exists.
RECOMMENDATION OR RESOLUTION X :
l
, 1. Process as an Observation.
- 2. Consumers Power Company should consider developing system description / design l

EXAMPLES OF INCONSISTENCIES:
- 1. FSAR page 10.4-37 states "The capacity of the auxiliary feedwater pun.p is equal to that flow at 105F which, when injected in the steam generator, will offset by evaporation the decay heat released following a reactor trip from full powar." One could be lead to believe that this means +. hat at the time when water is injected that this offset occurs. B&W calculation 86-1143885-01 shows that t = 50 sec is the point where this offset occurs, although water must be injected at t = A0 sec (per the B&W interface document). Furthermore, the B&W interface document states that this offset occurs at t = 30 sec.
- 2. Neither the B&W criteria document nor the FSAR make it clear whether the APCSB 9-2 method is the basis for demonstrating compliance with the offset condition discussed above.
- 3. Bechtel letter BLC-18114 states that ". . .AFW temperature could be as high as 105 F in the unlikely event that service water is used." Bechtel calcu-lation FM-4117-28(Q) shows that the condensate storage tar.k temperature could be as high as 135 F. This would indicate that there may be conditions under which the 105 F service water temperature would be lower than the expected condensate temperature.

Control Room HVAC Toxic Chemical Detectors DCV PROGRAM AREA OR TASK (F APPLICABLE):
Review Topic I.2-3 Accident Analysis Considerations Calculation Review DESCRIPTlON OF CONCERN:
Calculation FM-505-9(Q) is documentation of a computer code development for predicting corgentration of toxic chemicals in the control room following a chemical release.
The model used assumes that the toxic chemical which is introduced through the air intake is instantaneously distributed in the entire control room volume. The toxic ch:mical would actually be at higher concentrations in the vicinity of the HVAC supply than the exhaust or return during the initial transient. The concern is that the model underestimates the concentration to which operators in the vicinity of the air supply are exposed.
SicNFICANCE OF CONCERN:
For chemicals with short term (TLV-STEL) or time weighted average (TLV-TWA) threshold limits, the assumption is reasonable; but, for ceiling threshold limits (TLV-C) that concentration should not be exceeded even instantaneously. This applies to hydrogen chloride and boron trifluoride (used as a basis in the calculation for boron tri-chloride). Depending on the rate of dispersion of the HVAC supply, thesa instanta-nrous ceiling limits could be exceeded by a factor of ten using the detector sensitiv-ity calculated in calculation FM-0505-56(Q) using the computer code from FM-0505-9(Q).
REC 0 EMENDATION X OR RESOLUTION :
Access the potential for adverse physiological effects, considering both dispersi.on l
and toxicity.

DESCRIPTION OF CONCERN
)
in the process of reviewing calculations, it has been observed that some final The calculations are outdated, or use preliminary or outdated information.
technical impact has been evoluoted by TERA as part of the calculation review process, and geneiolly there are no cdverse effects. However, the question raised by repeated obsc.votions is whether the absence of adverse technical calculations are impact in the semple selected is sufficient evidence that controlled adequately to ensure there are no technical discrepancies throughout the entire design.
o A brief summary of specific instances is provided here to establish an under-standing of the nature of the concern observed thus for.
Calculation FM-4321-22(G), approved 5/9/78, is categorized " final." Its purpose is to establish the number and size of the control room pressurization tanks. 3 The The calculation concludes with a selection of four tanks (each 1,210 ft ).
current P&lD shows two tanks. Technically, two tanks are as adequate as four provided the total volume is the same. The calculation establishes that volume.
A check of purchased tank volume is sufficient to ensure that the sizing is technically odequate; however, the calculation is not current.
Calculation FM-4321-07(G) was transmitted to TERA on 8/12/83 as Rev. O, but the transmittel letter stated that it was being revised. Revision I was transmitted on 9/27/83, after being requested by TERA. The cpproval dates for Revisions 0 and I are 11/1/76 and 12/15/77, respectively. The last revision was, therefore, released over five years after approval. At the time of release the drawings referenced in the calculation had all been superseded as follows:
1 TERACORPORATION
Drawing No. Referenced Rev. Current Rev.
i 16 A-25 15 j A-48 1 15 A-49 1 0 7 A-50 3 10 A-51 0 12 C-207 C-208 0 11 5
C-222 1 The technical review of the calculation, which determines exfiltration and infiltration rates, evaluated the consequence of the outdated information to be insignificant in general. it was noted in the review that the leak rate is essentially only a function of the air tight door designs, and the drawings do not yet address specific design details. The calculation used reasonably atto~ noble values for the door leckage. This leaves open the issue of final confirmation of the leakage rate, which presumably will be addressed in a revision to the calculation.
Calculation CPM-4321-8 references FM-4321-07 for estimating the exfiltration, but then assumes a rate of 25 cfm at 1/8" w.g. The referenced calculation gives a value at 1/4" w.g., not at 1/8" w.g. Using the methods of that calculation, the TERA reviewer calculated a leak rate of 50 cfm for 1/8" w.g. Calculation CPM-l 4321-8 also assumes that leak rate is linear when it isn't linear in the referenced calculation. These facts appear to indicate a lack of appropriate interface between the calculations. The technical consequences were then reviewed and TERA determined they were insignificant. Calculation CPM-4?.21-8 determined the required flow rate of the pressurization system to be 75 cpm during the 25 second pressurization period, but an arbitrary margin was added increasing the sizing to 100 cim. The reviewer estimate is 90 cfm without margin. Further-more, the system is actually sized for 350 cim, per the FSAR.
- Calculation FM-0505-56(Q) was used for back-up to a design data transmittal in an IOM from J. N. Vance to L. H. Curtis dated 4/7/80. The calculation was not checked or approved of the time the memo was released, and this fact was noted TERACORPORATION
In the memo along with a commitment to update the data for any significant changes. A comparison of the approved calculation ed the memo shows 3 that the detector sensitivity for propylene oxide changed from 18,000 mg/m in the 3
memo to 45,000 mg/m in the final calculation. This means that the memo conservatively required a more sensitive detection level. The memo was not revised, but it isn't clear whether the control procedures would have resulted in an update had the preliminary results been unconservative.
i h
_ Calculation 55 0 0 ile No.1-8) was released final to support a conclus on t at floor flexibility could be neglected in seismic design. It referenced spectra from calculation 50 l19(Q) which was preliminary. It isn't possible to conclusively determine that the study would have been reassessed offer the referenced calculation was finalized.
In summary, each instance described above raises questions regarding the process for updating calculations, although no technical deficiencies have occurred.
MCAR 30 describes a technical deficiency which did occur, and it concludes that the failure to implement EDP 4.37 " Design Calculations" was partially the cause.
The concern here is that this procedure may not teve been implemented even though no significant technical problem resulted. Such a failure could have consecpences in other calculations which are not part of the sample.

silicone foam in the seal design as compared to that tested; different cable construc-tion materials from those used in the test (i.e., those tested were EPR/hypalon whereas Midland cables include several that are neoprene Jacketed); and use of a larger conduit size for certain penetrations as compared to the penetration conduit size used in the test.
SIGNFICANCE OF CONCERN:
The significance of these discrepancies is questionable with the recent notice that this design will not be used and that a new design will be developed; however, the reason that this design was rejected was due to the difficulty in pulling cables in the future. This should be tracked as an Observation.
RECOMMENDATION X OR RESOLUTION :
TERA perform subsequent evaluation on the revised design to verify that similar j discrepancies do not occur. Resolved as an Observation.

11.12-1, Fire Protection DESCRIPTION OF CONCERN:
The Teledyne emergency lighting unit, Model 2SGL10012-80, was not tested to demonstrate the full 8-hour capacity. The functional test prior to and after the seismic qualification test consisted of only depressing the test switch to simulate loss of power, rather than a time duration test. Also, the model numbers do not agree for the model listed to be installed, and the one tested.
SIGNIFICANCE OF CONCERN: be regarded as The lack of functional testing for the Teledyne unit should an observation. From the documents reviewed, it appears that the discrepancies relative to model numbers tested and those requested for installation and the lack of adequate functional testing have been identified by Bechtel and should be resolved as part of the Bechtel review process.
