Dear Sir:

The potential defect related to a transmitter manufactured by Rosemount, Inc. which we utilized in the control system of components furnished TVA for the Hartsville and Phipps Bend Nuclear Power Plants.

This letter is to inform you that Carrier has retrofitted all of the components involved in this notification with new circuit boards and we now consider this matter closed.

Under a separate letterhead, we are also informing Mr. Gregory P. Nicely, TVA, Division of Purchasing, Chattanooga, Tennessee 37401.
