Dear Mr. Kay:
SUBJECT:
SYSTEMATIC EVALUATION PROGRAM TOPICS, III-2, WIND AND TORNADO LOADINCS, III-7.B., DESIGN CODES, DESIGN CRITERIA, LOAD COMBINATIONS AND REACTOR CAVITY DESIGN AND III-6, SEISMIC DESIGN CONSIDERATIONS - YANKEE R0WE We are continuing our review of the above topics and require the additional information described in the enclosures.
The information will be used to review the capability of yoJr plant to resist seismic loads in combination with other loads and to resist tornado wind and pressure loads.
It will also allow us to identify structural elements affected by code changes.
The information is required by NRC contractors who are performing analyses on the above subjects.
In order for the contractors to maintain their schedules, please provide a copy of your responses directly to the contrac-tors as indicated below and one copy to the NRC.-
You are requested to submit the additional information described in the enclosure within 30 days of your receipt of this letter.
Please refer to the topic numbers in your response.
Mail the responses to Enclosure 1 to:
Ting Lo Lawrence Livemore Laboratory Mail Station L-90 P. O. Box 808 Livemore, California 94550 Mail the responses to Enclosure 2 to:
Franklin Research Center Division of the Franklin Institute Benjamin Franklin Parkway Philadelphia, Pa.

ENCLOSURE 1 Containment (Reactor Building) Structure
- 1..Orawing index including. titles (or descriptions) and corresponding drawing
~ numbers.
2.
Layout and structural drawings with sufficient structural information on the containment and its support and of the internal structures so that a dynamic enalysis model can be constructed.
Detailed drawings should also be incluced for rebar, liner, liner anchors columns, bracing, areas of discontinuity (excluding penetrations) such as dome-wall'or dome-ring girder-wall, and wall base slab.
3.
Detailed structural drawings of footings, basemats and piles (if applicable).
4.
Equipment location (arrangement) drawings, center of gre.vity, and mass information (including mass moment of inertia) for major heavy equipment such as reactor vessel, steam generator, tanks, cranes, condensers, steam drums,_etc.
If the reactor coolant loop was coupled with the structure in the analysis, provide the simplified reactor coolant loop model (e.g.,
computer input listing and input descriptions) if_ available; otherwise, supply mass and mass location information.
