Subject:
SEP Tcpic III - 7.B, Technical Information
Dear Ms. McKenna:
Enclosed are three (3) letters from Cygna Energy Services. These letters contain information requested by the staff and your technical consultants during their review of Topic III-7.B.
Your staff have already received this material informally.
The Cygna letter (86064.031) dated May 28, 1987 responds to your concern that snow loads should be combined with NRC spectra seismic loads.
This Cygna letter is the basis for our response to that issue which the staff raised via Reference (b), Item II.2.B.
The Yankee response, and our commitment to perform a plant upgrade, is presented in Reference (c).
The Cygna letter (86064.032), dated June 1, 1987 presents load data necessary for the evaluation of the Vapor Container (VC) column anchor bolts. The staff has stated that the information provided in this Cygna letter is sufficient to resolve their concern.
The third letter (86064.030), dated May 22, 1987 contains information regarding the VC column-to-shell connection.
As we explained during our meeting of May 18-20, 1987 this connection was evaluated by Cygna during the original SEP Topic III-6 analysis of the VC (c. 1980). At that time it was concluded that this column-to-shell connection was not critically stressed and need not be analyzed in detail. Cygna's VC finite element model is relatively unrefined for this part of the structure; consequently, comprehensive stress data is presently unavailable.

Subject:
Effect of 40 psf Snow Load to the PAB Yankee Rowe SEP Job No. 86064
Dear Bruce:
Cygna has cornpleted a seismic analysis of the PAB with the addition of a 40 psi snow load. This snow load was considered as an additional mass lumped at the PAB roof.
When the building was subjected to NRC spectrum loading, the following effects were observed:
1.
The fundamental frequency of the PAB is shifted from 4.55 Hz to 3.90 Hz (a reduction of 14%). This reduction in frequency is actually less because the in-plane stiffness of the steel roof deck was not considered in the original and new analyses. Consequently, the frequencies of the peaks in the ARS at the steel deck roof locations will be reduced by ! css than 14 Since this percentage is less than the 15% broadening of the spectral peaks, the qualification of the piping systems and equipment will not be affected, in addition, for the systems with fundamental frequencies greater than 5 Hz, the shif t in ARS peaks may reduce their seismic input.
The ARS at the locations of concrete slab roof, radioactive pipe tunnel, and concrete floor slab are not expected to be significantly affected by the additional snow mass (see item 3).
2.
The seismic inertia forces developed in the steel elements and their connections are increased by 38% Consequently, the new vertical diagonal brace along Column Line 8, the brace-to-stab connection at Column Lines G San Francisco Boston Chicago Parstpany
i

Mr. Bruce W. Holmgren Yankee Atomic Electric Comapny Job No. 86064 Page 2
& 8, and the beam-to-shear wall connections at Column Lines G & 5.5, Fb &
6, and Ec & 6 must be upgraded.
All other steel elements and their connections have sufficient capacity to take a 38% load increase.
The upgrade of the brace and connections will be designed in accordance to the "Scismic Reevaluation and Retrofit Criteria for YNPS", Doc. No. DC-1, Rev. 5, May 1987. The preliminary design will be forwarded to you soon.
3.
The additional snow mass is approximately equal to 8.2% and 1.1% of the total tributary mass lumped at the PAB roof and the total mass of the PAB, respectively. Therefore, the effect of the snow mass to the overall dynamic response of the PAB is insignificant.
If you have any questions or require further information, please call Nancy Williams or T.Y. Wang.
Very truly yours, M.N. Shulman Project Manager MNS/jst

Subject:
VC Element Forces for the Evaluation of Column Anchor Bolts Yankee Rowe SEP Job No. 86064
Dear Bruce:
The purpose of this letter is to formally transmit the element forces for the evaluation of the VC column anchor bolts. The same information (with minor modifications as marked) was telecopied to you on May 19, 1987.
The enclosed tables of column forces under different load cases were obtained using the old VC model (as shown in "VC Structural Analysis Report", Rev. 3,4/84) and the new VC model just generated for the evaluation of the soll. Also enclosed is a figure showing the Normal Force - Moment Interaction Diagram of the VC column base connection, with the column forces under different load combinations marked on it.
The results obtained using the old model are superseded by those using the new model.
However, since the new model was not used to perform the analyses for LOCA loads, the results from the old model are tabulated for reference.
If you have any questions, please contact T. Y. Wang.
Very truly yours,
