==Dear Mr. Crutchfield:==
In our April 22, 1983 submittal, "Structural Reanalysis Program for the Robert E. Ginna Nuclear Power Plant",
RGSE provided our recommendations for structural elements which should be considered for upgrade to withstand tornado effects.
The basis for selection of these structures is noted as those which are required to assure:
0 the integrity of the reactor coolant pressure
: boundary, the capability to shut the reactor down and maintain it in a safe shutdown condition, and o
the capability to prevent accidents which could result in offsite exposure in excess of the dose guidelines of 10 CFR Part 100.
Based upon the safe shutdown scenario discussed in Section 3.5 of the April 22 report, the attached list indicates those walls that RGSE currently considers safety-related and whose integrity must be maintained to assure safe shutdown.
Specifically, RGSE stated that the block walls whose failure could damage required main steam and feedwater line components in the intermediate
: building, and those which would affect the spent fuel assemblies, should be considered for upgrading.
No other block walls potentially exposed to tornado effects are considered as safety-related.
~ Several other block walls are located such that tornadoes could not cause. any structural
: damage, and thus were not evaluated in the April 22 report.
However, using the same safety design
: basis, the following additional walls are considered safety-related:
