Minichiplin Cycna Required item Comments Action By i

Cygna called the CPSES N-STAMP holder to understand their position on the oversize bolt holes. Mr. Sievers, who is responsible for site ASME QC and a member of the Code Committee, stated that both his and the ANI's interpretation of NF-4721 is that no code violation exists. Theic basis is that paragraph i

NF-4721(b) does not prohibit the use of oversize holes in bearing connections. Since the code has no prohibition, no violation exists. If engineering needs a smaller tolerance hole to meet their design criteria, that is up to engineering. For fabrication up to 1/4" oversize would be acceptable.

I told George that I was currently discussing these issues with Susan Spencer and Debra Anderson of TltGC0 (Dallas) and that he didn't have to get involved at this time.

In addition, I requested George to send me a copy of DCP-3, latest revision.

I asked George to make sure that the list of Cygna personnel on the gate log for May, 1984 was maintained. He told me that it was taken care of.

Gibbs & Hill L. Weingart Cygna Required item Comments Action By Steve and I discussed all of the questions which have arisen from the review of the stress analyses of the main steam inside and outside containment and the component cooling water system. The main purpose of this discussion was to assure that Gibbs & Hill understood both the nature and intent of the questions such that excessive iterations of response could be avoided.

Only one direct action item resulted from this conversation.

Steve will send a plot of the time history response of some of the axial restraints on the main steam inside containment. A comparison of these with the plots of the input forcing function along those runs will provide further assurance that the proper forcing functions were indeed applied for each system.

Dr. Iotti had made a very preliminary calculation of the dynamic load factor for the stability bumpers and determined that it was less than 1.0.

The calculation was based on the minimum frequency of the stability bumpers and assured the application of a triangular pulse at peak static bumper load.

Dr. Bjorkman commented that based on the uncertainties in the frequency calculation (support stiffuser and mass distribution),

pulse shape and duration one should use the maximum dynamic load factor.

Dr. Iotti agreed that this might be true. He mentioned that the impulse force is displacement dependent and that the problem was nonlinear. He recognized that the Cygna static calculation showed that the stability bumpers are not adequate. However, he believes that the bumpers can be qualified dynamically.

AcNy stem comments Dr. Bjorkman commented that this would probably be a first (i.e.,

qualify a support dynamically which a calculation shows is not adequate statically). This would require an extensive nonlinear time history analysis.

Dr. Iotti mentioned that dynamic qualification of the support was a possibility.

Dr. Bjorkman noted that dynamic qualification would be discussed internally at Cygna.

A Finne m TUGC0 J. Minichiello Cygna 1

Required item Comments Action By In response to Cygna's question on composite section weld calculations (earlier telcon 7/11/84), TUGC0 reviewed the 7 calculations with Cygna and agreed that the weld calculations were incomplete (did not include tensile effect) or inappropriate (wrong method used). Cygna's recalculations did show all these welds acceptable, so there is no design impact. TUGC0 has reviewed the 18" feedwater line supports for composite sections and found one section. TUGC0 is checking the weld for that section.

In addition, TUGC0 will check supports on the 30" service water lines for composite sections. Since these systems represent the largest, most highly loaded systems in the plant, this check by TUGC0 will ensure that there is no design impact plant-wide on this topic.

N. Williams will telephone D. Wade to determine the appropriate documentation required for this commitment.

Required item Comments Action By

Reference:

Conference Report of 15 March 1984

" Fire Protection and Hardware Weights for Cable Trays," D. Hunt, D. Nandi and J. Russ participating In response to the questions in the referenced conference report, Mr. Nandi gave me the attached sheets, marked Al to A10. The information on sheets Al to A9 is a summary of data from Binder 2323-El-1700, Issue 322, as noted on each sheet. The information on Sheet A10 is taken from manufacturer's catalogs or as noted.

Mr. Nandi told me that the weights of the splice plates and bolts used in the tray connections are included in the tray weight. He also stated that "Z" clips and friction clips are normal connections of the tray to the supports. Heavy duty clamps are used at a support, if a tray joint occurs there.

Doug told me that cover plates are not used at Comanche Peak because the insulating material used is rigid. The cable tray is not used to support the weight of the insulation.

Weights for Cable Trays Place:

CPSES (site)

Participants:

Doug Hunt Gibbs & Hill D. Nandi Gibbs & Hill John Russ Cygna Required item Comments Action By I spoke to Doug and Mr. Nandi (both of Gibb:: & Hill's Site Civil Group) about Mr. Walsh's request for weights of fire protection insulation and cover plates, splice plates and tray-support attachment hardware. Doug told me that the Site Hazards Group is responsible for determining which cable trays will require fire protection. This information is prepared by Mr. Jeff Spiegleman of TUGC0 and sent by CPPA to the Civil Group for evaluation of effects due to any additional weight. This evaluation is performed by adding the additional weight into the existing cable tray weight and comparing the total value to the design weight of 35 psf.

I gave Doug a copy of the RHR tra To expedite our response to Mr. Walsh's question,y segments.I asked Doug to provide the following information:

1.

Tray segment unit weight for the size of each tray segement.

Gibbs & Hill 2.

Cable fill weight per tray segment.

Gibbs & Hill 3.

Weight of insulation per tray segment.

Gibbs & Hill 4.

If any tray cover, and if so, its unit weight.

Gibbs & Hill 5.

The combined weight of Items 1 through 4.

Gibbs & Hill 6.

Weight of splice (" doubler") plates for the size of each Gibbs & Hill l

tray segment.

7.

Weight of the tray attachment clips and bolts for each Gibbs & Hill attachment.

On 3/17, Cygna discussed the allowable with Mr. Finneran. Mr.

Finneran stated that TUSI had documentation from the ASME Code permitting the use of the earlier revision. Cygna requested a JF/TUSI copy of the documentation for review.

p D. Rencher Texas Utilities J. Minichiello Cygna Required item Comments Action By Cygna requested response to the following two questions.

1.

In CC-1-031-008-533R, Cygna has noted another instance of a

" fixed" joint at an embed plate, rather than a " pin" joint (see comments on MS-1-004-001-C72S, dated 3/21).

In this case, a r

" fixed" assumption is needed, since self-weight was considered.

The Civil Spec (SS-30) requires stiffeners be provided (see attached).

a.

Is piece 7 considered to be the stiffener?

b.

Has the Civil Group provided guidelines for stiffeners?

c.

What direction has TUSI given the support designers in using embed plates as " fixed" connections?

d.

The designer appears to use conservative cales in determining plate loads. Then, he uses the highest plate allowables.

What is TUSI's direction for determining embed plate allowables?

a concrete free edge (i.e.,

openings, face of beam, 1

etc.) in any direction.

3.4

" Pin Connections" shall be assumed for load transfer to the embedded plates.

Only forces normal to the embedment (P-)

and forces in the plane of the embedment (S) may be transferred to the embedment.

Moments due to cantilever action or from any other source may be transferred to the embedment only when the embedment is stiffened for the calculated moment.

s 3.5 The loading pattern on sheet A4-1 and A4-3 assumes that the embedment is loaded at the midpoint of every span between pairs of studs for A4-1 and at every pair of studs.for A4-3.

In cases in which the load is distributed on more than one pair of studs, the full normal load (P) and only half of the plane load (S) should be considered when using the figures on sheet A4-2 and A4-4.

3.6 For capacity of embedded plate strips for loads acting on stud line see Cases 3 and 4 (A4-5 through A4-9)

- REV.1 4.0 CAPACITY of EMBEDDED PLATE STRIPS FOR LARGE ECCENTRIC LOADING 4.1 Tension and shear forces generated on the stud anchors by loads applied eccentric to the supporting stud group should be ca! ulated to insure no failure of the stud anchors.

{

4.2 Ultimate tension and shear capacities of the stud I

4 anchors shall be taken from reference 2 of this

{

Appendix.

l 4.3 The number of participating stud anchors may be

)

increased by welding stiffeners to the embedded plate j

_gg.f'g strips and to the support structure to ensure that the loading is spread to all the selected stud anchors.

j The embedded plate strip shall be checked for bending and shear.

[eEnY item comments 2.

In reviewing CC-1-028-022-S33K, Cygna has not found any checks of the hardware, other than references to previous design cales.

Cygnh has checked piece 3 (24" special riser clamp) against the Grinnell load sheets (attached). Using the " max operating temp" of <200*F from the line list, the emergency allowable for the clamp is (04' c-c):

E = 1.25 (16800)

= 21000 lb calc is N.= 21964 lb, this support may fail, assuming the above Since Ea a.

Since the calc states the original design loads were higher, what is the correct procedure for calculating clamp allowables?

b.

Has TUSI considered that one snubber may be more highly loaded than the other, due to pipe rotation?

Participants:

C. Ray J. Minichiello Cygna Required item Comments Ac: ion By In the original review of AB-1-61A, Cygna did not find a welded attachment calculation for CC-1-028-713-A33K. G8H stated that the calculation was referenced in the back of the QA books, under CC-1-028-113-A33K (by mistake). Cygna requested a copy of the G&H memo AM-WA-82 dated 5/12/82, (To: B. Roy/F. Colucci, From:

P. Bogart /V. Chirila) and verified that support -713 is similar to support -004, as stated in the memo (713 has a slightly larger trunnion diameter of 16" vs. 14").

Participants:

pg TUGC0 J. Minichiello, N. Williams Cygna Required item Comments Action By Cygna requested response or clarification on the following issues:

1)

For checking the welds for composite sections (i.e., a plate welded top and bottom to tube steel or a wide flange), Cygna noted errors in the following calculations, a) MS-1-003-005-S72R, Rev. I b) MS-1-002-007-C72K, Rev. 2 c) MS-1-004-004-S72R, Rev. O d) MS-1-001-003-S72R, Rev. 2 e) MS-1-002-004-S72R, Rev. 1 f) MS-1-003-006-S72R, Rev. 3 g) MS-1-004-003-S72R, Rev. 4 Mr. Finneran will review these calculations and call Cygna back later today to discuss them.

2)

For double trunnions, riser clamps, or trapeze arrangements with cinched U-bolts, TUGC0 has answered that they use a 50/50 load split on the two sides, rather than, say, 66/33. For justifica-tion in terms of piping rotation, Mr. Finneran referenced his Affidavit on axial restraints and torsional loads due to piping rotation. Cygna will review this document as soon as we receive it. Cygna also refereneced NUREG/CR-2175, which discusses the effect of clearance mismatch on load split for dual snubber arrangements. Mr. Finneran will obtain a copy for review. M r.

Finneran did state that the imbalance due to rotation was a self-limiting load, since one calculated it from the full piping rotation. Mr. Finneran also referenced his Affidavit on seismic safety factors. Cygna will also review this document.
