Dear Mr. Hoffman:
SUBJECT:
SYSTEMATIC EVALUATION PROGRAM TOPICS, III-2, WIND AND TORNADO LOADINGS, III-7.B. DESIGN CODES, DESIGN CRITERIA, LOAD CO M INATIONS AND REACTOR CAVITY DESIGN AND III-6, SEISMIC DESIGN CONSIDERATIONS - BIG ROCK POINT 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 l
with other loads and to resist tornado wird 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 tha above subjects.
In order for thr. contractors to maintain their schedules, please provida a copy of your responses directty to the contrac-tors as indicated below and one copy to the NRC.
You are requested to submit the additional infonnation 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:

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 penetrations) such as dome-wall or dome-ring girder-wall, and wall base slab.
3.
Detailed structural drawingt of footings, basemats and piles (if applicable).
4.
Equipment location s.trrang(ment) 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 simp 1.ified reactor coolant loop model (e.g.,
computer input listing and input descriptions) if available; otherwise, supply mass and mass location 'information.
5.
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.
