Dear Mr. Couns11:
SUBJECT:
SYSTEMATIC EVALUATION PROGRAM TOPICS, III-2, WIND AND TORNAD0 LOADINGS, III-7.B., DESIGN CODES, DESIGN CRITERIA, LOAD COMBINATIONS AND REACTOR CAVITY DESIGN AND III-6, SEISMIC DESIGN CONSIDERATIONS - HADDAM NECK 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 your 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 describec 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 Livermore Laboratory Mail Station L-90 P. O. Box 808 Livermore, California 9a550 Mail the responses to Enclosure 2 to:

ENCLOSURE 1 Containment (Reactor Building) Structure
- 11. ' Drawing 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 analysis model can be constructed.
Detailed drawings should also be included for rebar, liner, liner anchors, columns, bracing, areas of discontinuity (excluding penetratior.s) 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 gravity, 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.
5.
Operating and design temperature conditions inside and outside of contain-ment for summer and winter.
6.
If the seismic reanalysis of the containment structure has been performed, provide.the model (mass properties,-member stiffnesses, soil stiffnesses if applicable, etc.) used and the results.
