Millstone Unit No. 3 I.E. Bulletin No. 79-28 In accordance with the requirements of Reference (1), it has been determined that there are plans to install NAMC0 Model EA180 stem mounted limit switches at the Millstone Nuclear Power Station Unit No. 3. A review has indicated that the vendor holding Purchase Order 2472.110-185 for Electric, Electro-Hydraulic and Air-0perated Control Valves is using the subject limit switches.

The vendor, Fisher Controls Company, has determined that they are in possession of 201 of the subject limit switches with the applicable code dates, i.e. , 02-79 through 08-79. Fisher Controls is now in the process of correcting the gasket problem on these switches in accordance with the NAMC0 Control's extract attached to Reference (1).

We trust this information satisfactorily responds to the Reference (1) concerns.

Very truly yours, NORTHEAST NUCLEAR ENERGY CO.
