SUMMARY

OF SIXTH MEETING ON CONFIRMED ITEMS AtO FINDINGS February 1,1984 Midland IDCV Program A meeting was held on February 1,1984 at Bechtel's Ann Arbor, Michigan offices to obtain additional information related to confirmed items identified in the IDCVP monthly status report dated Janucry 13, 1984 and to status other outstanding items identified previously. Attachment I identifies the attendees of the meeting which included representatives of TERA, CPC, Bechtel, and NRC. Attachment 2 presents the ogendo used for the meeting.

Howard Levin, TERA, opened the meeting with a discussion of the agendo and a summary of the purpose of the meeting. A brief discussion of the 10-day response time was held. It was agreed that Bechtel would use overnight delivery services such as Federal Express to expedite the receipt of information by TERA. TERA ocknowledged the receipt of project responses to previous OCRs and stated that those responses were being evoluoted. The meeting then proceeded with its primary objective which is to ensure that all pcrticipants have o complete understanding of the technical issues expressed as confirmed items.

Each r.ew confirmed item contained in the Status Report dated January 13 was discussed. This is intended to enable Midland Project personnel to identify additional information that may have bearing on the issues. Clarification or presentation of additional information by Midland Project personnel is also sought so that specific issues may be further dispositioned directly.

The status of previously outstanding confirmed items end findings was also discussed except for those noted in the meeting announcement. The meeting announcement listed certain OCRs as being on hold or that sufficient informo-tion is available for TERA to disposition the item. A summary of the significant aspects of the discussion is provided in Attachment 3 along with any course of action identified. The responsible TERA personnel described each item, followed ,

by discussion by either CPC or Bechtel personnel as appropriate. The order in which the OCRs were discussed was revised at the start of the discussion period to achieve maximum efficiency in the use of the available time.

ATTACHMENT 3 DISCUSSION OF COW!RMED ITEMS, FINDINGS, OBSERVATIONS, AtO RESOLVED ITEMS s

3201-008-C-109. This OCR is concerned with the 60-second coast down inter-lock. TERA stated that-it bei received no new information concerning this item

'since the lost meeting. Bechtel stated that they were already aware of this concern based upon the receipt of an I&E Notice. Bechtel has provioed information for TERA in a letter dated January 25. TERA stated that it will review this letter. ,

3201-008-C-110. This ' confirmed item resulted from apparent discrepancies noted by TERA between the ' OPE-l load tobviation and a similar tabulation prepared by TERA. Bechtel stated that SCN-4082 is currently in preparation and is being reelewed by CPC. TERA stated that it had reviewed a draft of

.SCN-4082 cnd tNot it appeats to be at least in part responsible to the concern.

Receipt of this SCN is required before TERA con determine appropriate action to be tcken on this OCR.

3201-008-C-Il1. Bechtel stated that SAR change notice 4082 ofso addresses the incorisistency noted in this OCR concerning battery charger capabilities.

3201-008-C-132. Bechtel stated that a January revision to the drawing refer-enced IEC-132 should resolve' t'his OCR. It-was stated that the FSAR describes the octual systera basis and that the drawings were logging behind the FSAR. It was also noted that. CPC determines relay set points and advises Bechtel, and then Bechtel revises the drawings. TERA will advise CPC if odditional information is necessary to disposition C-132.

3201-008 C-I34. The 12OP sequencer logic contained a Unit I under-voltage initiotion of Unit 2 standby electric power. Bechtel stated that this is no longer considered necessary and that a revision was in process to update the documen-totion. It 'wos noted that this item is on interface between the control systems and electrical groups. TERA requested odditional information concerning the B-84-99 -- I

~

p y y- .~ .,.,-,_ _ - _ . - . , - , - . .

process by which a previous revision resulted in the addition of this initiation.

The addition of this logic was a fairly recent revision to the drawing; therefore, the revision currently in process simply restores the design to its previous basis.

TERA requested information on why the logic was changed previously.

3201-008-C-135. The project stated that this item had been noted within the project in August when it was determined that no action need be taken until offer fuel load. It is considered by the project that the diesel generator lockout relay con be manually reset allowing closing of the normal incoming breaker. It is the project'.s position that the system functions properly as presently designcd and there is no need to revise the design at this time. The need for a revision is only a matter of convenience rather than a functional requirement. Bechtel has provided documentation of the project position in a letter to TERA dated January 8, 1984. TERA will review this information and determine the disposition of this OCR.

3201-008-F-047. This finding is concerned with storage and maintenance proc-tices at the Midland site. TERA has received various documents concerning this issue including a copy of the Task Force proposal for reorganization of the storage and maintenance program. TERA has also had discussions with project personnel to obtain further information concerning this item. The specific concerns listed in F-047 have not yet been addressed. It was expected that a formal response would have been received by the meeting date. TERA is awaiting receipt of an approved version of the storage and maintenance procedure FPG5.000. With this information and the response to the specific l Items in F-047, TERA should be able to disposition this finding.

3201-008-F-049. This finding is concerned with separation criterio, in particular for air-lined cables. TERA has been advised that air-lined cables will be bundled and wrapped and that the program for cobie separation verification has not been finalized. TERA requested copies of documentation which states that construc-j tion will bundle and wrap air-lined cable. TERA will retain this item os a finding g pending review of the inspection plan to be implemented to verify cable separation.

B-84-99 2

3201-008-C-l12. This OCR is concerned with the calculation of diesel generator exhaust back pressure. The OCR noted that the original calculation performed by Bechtel showed a back pressure slightly in excess of the 10 inches allowed by the vendor. Bechtel stated that the calculation has been revised to reflect newer information. TERA will review the revised calculation and will meet with Bechtel to walk through the calculation per the calculation release procedure so that the calculation may be released upon its opproval, which is expected within the next two weeks.

3201-008-C-113. The air start system supplies air for the pneumatic control ,

system for the diesel generator. TERA needs additional information to verify that adequate air is available to operate the pneumatic control system after the diesel starts assuming that the non-category I air compressors do not supply additional air to the starting air receivers. Bechtel stated that the starting air receivers are sized for control system use and that it was in the vendor's scope to properly size the occumulators. Bechtel will determine what additional information is ovalloble on the subject.

3201-008-F-050. This finding concerns potential misrouting of cable and is being retained as on unresolved finding pending CPC's final disposition of NCR-A-5000-6-CV. The dispostion of this NCR will provide final program interpretation of the cable routing criterio.

3201-008-F-054. A Bechtel letter dated January 19, 1984 provides additional information concerning this finding. TERA stated that an issue remains based l vpon the CPC response which transcends the specific noted inconsistency. The concern is how temporary attachment records are used; specifically, CPC response would indicate that the temporary attachment record is completed upon l

satisfactory removal of the attachment lugs or is on after-the-fact record.

l TERA's concern is that normal industry practice uses the temporary attachment record as a controlling document, that is, a before-the-fact record. This way the record becomes an open item that must be closed before an installation con be completed.

B-84-99 3

• 3201-008-C-097. This confirmed item is concerned with the capability to re-establish outside air to the control room following isolation of the control room HVAC system and given a single failure. Bechtel stated that a hand wheel is available to allow manual operation of the volve. It was further stated that the access study performed as a result of TMI shows that access can be gained to the hand wheels.

3201-008-C-129. This confirmed item is concerned with the specified closing time for dampers. Bechtel stated that the I-second closing time opplies to dampers downstream of the ones TERA was reviewing. Therefore, the system must be capable of detecting hazardous material within 4 seconds and closing volves within I second giving a total 5-second time. The 5-second value should be used for further reviews.

Bechtel also discussed the apparent discrepancies between the so-called Appen-dix A and Appendix D gases. The hozordous gas monitoring system design objective was to reach a lower limit than specified in the FSAR. Appendix A (Note 1) is the actual response to design criterio. The 5-second and 16-second values specified for hydrogen bromide and bromine meet the FSAR criteria even though they are different from the general 4-second detection time used for other materials. The actual response of the system is such that concentrations in the control room are within acceptable limits.

TERA had noted on page 10, paragraph 6.l.2(b) of the specification that a l reference to Appendix A is made and commented that it appears the reference should be to Appendix D. Bechtel stated that the reference to Appendix A is correct in that the paragraph is referring to the extended specific mode and that no gases are currently in this group. Appendix D refers to newly identified gases which are currently being tested. When the testing is complete they will be l

included in Appendix A. TERA had also noted that the specification for the hozordous gas monitoring system is based upon a 2-second isolation time for the dampers. This seemed to be in conflict with a 3-second isolation time in a damper specification. Bechtel stated that the 3-second closing time applied to other dampers and that the dampers in question actually have a l-second closure B-84-99 4 l

time. The 2-second value was supplied to the hazardous monitoring system vendor as a degree of conservatism since the longer it takes to close the dompers the more sensitive the monitoring system must be in order to meet the FSAR commitments regarding concentrations in the control room. Therefore, it can be concluded that the system is correctly designed and that the apparent discrepan-

- cies are in fact conservo!!ve margins being opplied to the various vendors.

TERA will review available information and request additional information from Bechtel in order to disposition this item.

3201-008-F-055. TERA has obtained information concerning this item from CPC personnel. TERA is awaiting the receipt of Bechtel/CPC formal response to the finding and then will determine the oppropriate course of oction.

. 3201-008-F-056. No response has been received to date on this item.

3201-008-F-091. This OCR is concerned with the lesson plan for POCl covering hanger inspections. TERA noted that a CPC memo of 9/29/83 indicates that due to word processing errors activity 34 was omitted from the lesson plan, but that the POCl was covered in its entirety during the lesson. TERA will disposition this item pending receipt of lesson plan revisions in effect prior and subsequent to the lesson plcn reviewed by ICV personnel.

3201-008-C-092. This confirmed item was concerned with a possible bios in the method of assigning hongers to be used for qualification of inspectors. The current program requires Level lli personnel to assign hongers, although previ-ously the qualifying QCE was selecting his own hanger. TERA is awaiting the receipt of additional information in order to disposition this item.

3201-008-C-093. CPC is preparing a response to this confirmed item. TERA will evoluote the response and disposition the confirmed item accordingly.

3201-008-C-094. This confirmed item resulted from physical verification of the control room HVAC system. Four inconsistencies were noted in the physical verification activity. Of these, CPC noted that TERA's first item was due to the hangers being destatused during the time the ICV re: viewers were conducting the B-84-99 5

- review in order to enable removal of a test coupon for destructive testing. The entire section will eventually be removed. TERA will resolve this item and a re-Inspection will be conducted later. CPC stated that item 2 was checked by CPC and found to be acceptable. TERA will review and evoluote the CPC response.

With regard to items 3 and 4 of this OCR, CPC stated that per the convention used on the project, the flange connections which TERA inspected are not considered part of the completed duct section, but rather are within the inspection boundaries of the incomplete dampers. TERA will disposition these two items.

3201-008-C-095. Information presented to TERA indicates that a means is ovallable to indirectly verify the welders' qualification to o specific WPS.

Recent revisions to documenting procedures require the recording of the date that a weld was actually formed, thus removing this item from future concern.

CPC ogreed to provide a formal response that TERA personnel con review in order to disposition the OCR.

3201-008-C-096. TERA is awaiting the receipt of CPC response to inconsis-tencies noted with regard to certain ducts and hangers associated with the HVAC system.

3201-008-C-125. This item has been divided into two sub-items. Bechtel civil soils is doing a short study to determine the compatibility between stick and finite element models.

3201-008-C-130. This OCR was concerned with the source of the seismic force values used in calculation DQ52.0(q). Bechtel advised that Attachment C to the calculation contains these values. TERA will determine whether Attachment C

! is available and, if not, will make a request for this information.

3201-008-C-131. Bechtel has updated its calculations with information on why the model overstates the moments in the north-south wall footing strips. TERA will review the revision of Bechtel's calculations.

o 3201-008-C-99, C-101-C-108, C-071, C-I l3-C-! ! 7, and C-I l 9-C-122. The general status of these civil structural items was discussed. CPC and Bechtel are prepering additional information for TERA's review. It is expected that this information will be transmitted to TERA approximately February 8 in order that the information be reviewed prior to the next OCR meeting. TERA recommend-ed that a separate OCR meeting be held on civil structural items. It was agreed that consideration will be given to o two-day meeting so that more detailed discussions con be held concerning the responses being prepared to the OCR.
