ITEMS DISCUSSED APRIL 10. 1979 ef% ma.;f!g Effluent Treatment Systems Branch M . f r. '.. . 1., 3., 5. The applicant's proposed' response for FSAR Revision 20 ~ will resolve. these items. N 2 '. ,; Staff review of the Section 11'.5 as revised by FSAR. M Revision 19 indicated several items which must be E @Y clarified or modified. These areas" include.the' %' M 9 footnotes of Table 11.5-1, sheet 2 of Table 11.5-2, d% footnote 7 of Table 11.5-4. Table 11.5-5, Table 11.5-6 j//O IV,'Section 11.5.2.2.7 and Section 11.5.2.3. 3 ih 4. Unresolved. The staff stated that a design solution f E.Mli such as that implemented by Pilgrim Unit 2 might also be )lM acceptable in lieu of a design solution based upon ECCS pump room filtration. However, the staff remains fim X @y : in its position that a design solution to mitigate f pump seal leakage after an accident is required. The n 'a.

Unresolved. The applicant has proposed a technical j specification for containment integrity during refueling similar to that for Palisades (i.e., the equipment hatch _ _._ ? which opens to the auxiliary building may be open during refueling)' The analysis for a fuel handling accident y':i would assume the equipment hatch is manually closed s i al within 30 minutes. Further radiological release ,f analyses assuming failure of a full fuel Tssembly, the open d equipment hatch and other flow paths are required to support the applicant's proposed position. The staff also indicated it may not accept the 48-inch purge lines x being in operation while fuel handling operations are'in ~ F.M progress since these lines would not be isolated until 14 y 30 seconds after a radiological release accident, we. 3., ',' H 2. Same as ETSB Item 4. L;; '2 SW,Q 3. Unresolved. The staff is concerned that frequent testing p,y,3 of turbine stop valves may contribute to damage to steam generator tubes as occurred at Oconee.

Initial item resolved by Revision 19. An error in Table /j 12.3-2 will be corrected. The design does not provide for W9[jb pi criticality monitoring in the new fuel storage area when handling is not in progress; therefore an exemption to J. ';/ 10 CFR 70.24 will be applied 'for. b '1 L'i?.. The applicant will revise the FSAR to provide more positive 2. access control to the fuel tube area, for recognition 9: of the potential for exposure in the area, and to provide ~i>#- for portable monitoring devices. id: .,'.j.

Staff review is continuing but no further infomation 5 is needed from applicant at this time. [ 5. The staff requires all of Chapter 4 and 15 to be i revised to use the approved version of TACO (BAW-10784, Revision 1. August 1977).

(::.f', 3. Unresolved. Tne staff asked the applicant to identify @2, Apq the criteria used to determine that the nodalization model .N is adequate. The staff emphasized that cases which may be N{-h} conservative for the loadings on the cavity wall may not f. necessarily be conservative for the loadings on the vessel. f The staff inquired about the horizontal boundary through {',. y; the nozzle centerlines for the expanded nodalization model. The staff will require that any mechanistic /. -

[.l d assumptions used for the treatment of insulation on venting of cavity analyses be capable of being

';p demonstrated either experimentally or analytically. ..N J f The staff plans to issue guidelines on Task A-2 in NUREG-0510 in June,1979. 4. Resolved, subject to review completion by Structural Engineering Branch, k S. The applicant plans to show that MSIV leakage with sonic flow through a ruptured 0TSG tube, would be negligible. - Erie and Davis Besse I were cited as examples. The applicant is considering deletion of the leakage penetration /, system. ( d 6. The staff noted that the technical specifications do not specify leakage limits for closed systems outside 4 containment (e.g., containment spray systems, etc.) during hydro testing. Justification for these proposed limits f, ;' f ',: 1 o, is required. ,'i There is an inconsistency between the Midland technical l'q specificattors and FSAR Chapter 6 regarding 10 CFR J. 50 Appendix J. Timely approval by the Commission of a change to Appendix J is not currently anticipated. h Auxiliary Systems Branch aa 1. Staff review of the applicant's response by Revision 19 4 is in progress. 2.

~ 1. Not discussed. 3-W9 2. The OPTCON program will be submitted in April 1979. The response to .?, ~ request 130.21.in FSAR Revision 19 is based upon code material properties and " allowable stresses" refer to ACI-359. A subscript error will be MM corrected. u AJ{ 3. The' staff suggested that, if necessary, consideration be given to WO ' J, use of actual properties where, this can be justified and to use of a

g site' specific response spectra.

fC 4. The staff finds the applicants response to request 130.24 to be unacceptable. The distinctiori between structural damping and equipment 7 5,p damping was discussed during the meeting. The staff noted that OBE and SSE damping.was not treated adequately in the response. The staff .r.. 1 requested that the response to request 130.24 be revised to compare

:a 0BE and SSE at each point (both vertical and horizontal) for structural and mechanical damping using both RG 1.61 and site specific m

[, damping. Also clarify response to indicate whether RG 1.92 was used. ' c.J The applicant will respond in May 1979. -p rc 5. Unresolved. The applicant's response by FSAR Revision 19 transferred ^ A a the Bechtel topical report BP-TOP-1, with some modifications, to the Midland FSAR as Appendix 3D. - However the modifications do not - 'l provide all the information which was asked for during the staff's ~ t X:) generic review which resulted in acceptance-of Revision 3 cf the topical. .A Appendix 3D does not address how closely-spaced modes are handled; D 3 Wl and uses cyclic critaria based upon Revision 0 of the report which the 'O C staff found unacceptable. ' The staff requires that FSAR Appendix 3D ' '0 '- - be revised to respond to all requests issued as part of the staff's generic review of the earlier revisions of the topical report. lt o Geology / Seismology Branch .}' i9. 1. The staff does not at this time accept that the Michigan Basin Tectonic Province is separate from the large Central Stable Region &*10 tectonic province. Therefore, the staff does not accept the reference Mcs,.. acceleration value of 0.12g to which the Midland Plant has been built. T;- The staff's requirements will depend, in part, upon the approach T.M ultimately to be adopted for other plants (Sequoyah and Davis Besse). Further meetings with Consumers Power on this subject will be held. t.-
