Dear Bill:
I have enclosed a progress report on open items for Ginna.
Of the portion assigned to SMA, Newport Beach, the CRD support has been completed and the one remaining item is the primary coolant pump casing.
The report on this item will be forwarded when it becomes available.
Sincerely,
~;

Dear Tom:
The reference letter summarized the status of open items for Ginna NSSS equi pment.
At that time we were wafting further documentation on the control rod drives, control rod drive support structure and for the primary coolant pump casing at nozzle penetrations.
We received a Westinghouse analysis of the CRD housing,Ref.
2, for a 0.8g static coefficient and verified that the loadings us'e'd in the CRD housing seismi'c support analysis are correct and that stresses are within acceptable levels.
Therefore, the only remaining item is the primary coolant pump casing at nozzle penetrations.
In our last con-versation with Westinghouse, they were comparing the Ginna pump casing and nozzle loading to the San Onofre units for which a detailed finite element stress analysis has been conducted.
That comparison will be reviewed when received.
Very truly yours, STRUCTURAL MECHANICS ASSOCIATES, INC.
