Subject:  Our notification to you, Event Number 33081, at 11:36 am

          October 14, 1997



Dear Mr.  Saidan,



This notification involves a total of six (6) Foxboro Differential

Pressure Transmitters shipped to nuclear sites.  Five (5) transmitters

were shipped (7/26/96) to Vermont Yankee, Model Number N-823DP-D3S1SH1

and one (1) transmitter shipped (3/11/97) to Consolidated Edison of New

York, Indian Point Station Number 2, Model N-823DP-D3S1SH2-F.



The problem with these transmitters is that Foxboro inadvertently shipped

the wrong electronics module, which is installed inside these

transmitters.  We shipped an electronics module which had not undergone

the seismic qualification tests required for this product, This module

is, however, from the same family as modules already nuclear qualified,

and is robust in design.  We immediately undertook to run random

vibration tests as a first step to assess its capability.  These tests

gave us confidence that the electronic modules would pass the nuclear

seismic requirements and we are on a path to perform these qualification

tests within the next two to four weeks.



We contacted both Vermont Yankee and Consolidated Edison of New York on

October 9, 1997.  We supplied the seismic and random vibration test data

to Vermont Yankee on October 10th to help them assess their application

for these transmitters.  We talked with Steve Kolpa on Tuesday morning,

October 14th.  He informed us that the vibration data had been reviewed

and that there was no immediate operability problem.  He asked that we

keep him informed when our qualification tests were completed.



Consolidated Edison of New York reported back, through a conversation

with Mr.  Alan Budnick, the General Manager of Quality Assurance

Oversight, on Friday October 10th, that this transmitter did not affect

plant operability.  This transmitter is used in the reactor coolant

system but is valved out and had no direct safety function.  It is only

used when the reactor is shut-down and its next use would be in

approximately two years.



We did, however, uncover another issue relating to Consolidated Edison of

New York.  We reviewed all purchase orders for this product, to make sure

that we had met all technical specifications.  We found that a

specification for normal radiation had been overlooked in



FOXBORO



this instance.  For this particular order, Consolidated Edison required

6000 rads, and our product does not quite meet this level.  We are

supplying our radiation test data to Consolidation Edison for their

review.  The data indicates a minimum of 4700 rads capability.

Consolidated Edison will review this data to determine if there is any

effect on transmitter life for its particular location.  If not, then the

transmitter will not be replaced.  If there is a problem, then the

transmitter will be replaced.
