This completes the staff's action for Item 4.5.3 of Generic Letter 83-28.

Copies of the related safety evaluation and the Technical Evaluation Report prepared by the staff's contractor, Idaho National Engineering Laboratory, are enclosed. By letter dated November 23, 1988, the staff inferred you that actior for Item 4.5.2 of Generic Letter 83-28 had been completed.
