          Millstone Nuclear Power Station Unit Nos. 1, 2 and 3

        10 CFR 21 Report Concerning Cracked Fuse Ferrule Defects

                           (NRC Event #31371)



In a letter dated December 13, 1996, Northeast Nuclear Energy Company

(NNECO) transmitted to the NRC a notification of a Substantial Safety

Hazard (SSH) at the Millstone Nuclear Power Station regarding cracked

fuse ferrules.  NNECO has identified an administrative error in

Attachment 1 of the letter which detailed our commitments regarding this

issue.  In section (vii)(b) of the letter NNECO committed that Millstone

Design Engineering Departments would develop a process to check and

replace the cracked fuses delineated in Section (ii)(a) of the report.

In Attachment 1 the referenced section for the fuses we would address was

incorrectly identified as Section (ii)(b).  A corrected copy of the

commitments associated with the letter is provided in Attachment 1.
