10 CFR PART 21 NOTIFICATION REGARDING HIGH FAILURE RATES OF BW/IP

(FORMERLY BORG-WARNER) PRESSURE SWITCHES INSTALLED ON BW/IP      

ELECTRO-HYDRAULIC ACTUATORS USED IN THE GAS TREATMENT, SERVICE   

WATER, AND HEATING AND VENTILATION SYSTEMS AT NINE MILE POINT    

UNIT 2  (REFER TO EVENT #31822 FOR ADDITIONAL INFORMATION.)      

                                                                 

ON FEBRUARY 20, 1997, NINE MILE POINT UNIT 2 MADE A NOTIFICATION 

TO THE NRC REGARDING THE EXISTENCE OF A DEVIATION OR             

NON-CONFORMANCE CONDITION IN A BASIC COMPONENT THAT WAS          

REPORTABLE UNDER 10 CFR PART 21 GUIDELINES.  THE BASIC COMPONENT 

WAS IDENTIFIED AS A SAFETY-RELATED PRESSURE SWITCH SUPPLIED BY   

BW/IP THAT MAY BE IN ONE OF FIVE PART NUMBERS, AND THE REPORT    

CITED A HIGH FAILURE RATE OF THESE PRESSURE SWITCHES.            

                                                                 

ENERTECH AND BW/IP ARE CURRENTLY INVESTIGATING THIS ISSUE.       

ENERTECH IS ALERTING ALL POTENTIALLY AFFECTED CUSTOMERS OF A     

REPORTED SAFETY-RELATED BASIC COMPONENT THAT IS CURRENTLY BEING  

INVESTIGATED BY NINE MILE POINT UNIT 2 UNDER 10 CFR PART 21      

GUIDELINES.  SINCE ENERTECH WAS NOT PART OF THE NINE MILE POINT  

EVALUATION PROCESS, ENERTECH HAS ALSO REQUESTED HARDWARE AND     

DOCUMENTATION FROM NINE MILE POINT PERSONNEL FOR BW/IP EVALUATION

OF THE STATED SITUATION.  ADDITIONALLY, ENERTECH REQUESTED       

FEEDBACK FROM POTENTIALLY AFFECTED CUSTOMERS.
