Subject:  Follow-up to ENERTECH March 3,1997 Letter regarding Niagara

          Mohawk Power Corporation: Non Conformance Report of BW/IP

          Pressure Switches.



On February 20, 1997 Niagara Mohawk Power Corporation, Nine Mile Point

Unit #2, submitted to the NRC Operations Center their sixty (60) day

evaluation report. In Nine Miles opinion, a deviation or non conformance

condition exists in a basic component that is reportable under Part 21

guidelines.  The basic component is identified as a Safety Related

Pressure switch supplied by BW/IP that may be any one of five (5) part

numbers.



Since our first notification, ENERTECH has made numerous unsuccessful

attempts to have the Nine Mile Facility provide information required to

perform a root cause evaluation.  Without this information, ENERTECH is

unable to determine specific effected part numbers, failure mechanism,

and failure history.



All known users of the pressure switches in question have been notified

by ENERTECH.  An upgrade to a more advanced pressure switch has been

suggested to the affected Nuclear Power facilities.  No additional action

or status on ENERTECH's behalf can occur until Nine Mile Unit 2 provides

the requested items for evaluation.



If you have questions or need additional information, Please contact Mr.

John "Rusty" DeKleine, Director Quality Assurance, or myself at your

convenience at ENERTECH (714) 528-2301.



Sincerely,



ENERTECH
