On June q, 2019, Engine Systems Inc. (ESI) Issued Interim re.port 10CFR21-0125-INT, rev.O regarding an*

Identified deviation for which ESI wa1;1 unable to complete an evaluation within the 60-day requirement. Per the interim report, E:SI committed to complete the evaluation by July 31, 2019. The evaluation Is now complete and the deviation Is detennlned to be reportable in accordance with 1 OCFR Part 21.

Pursuant to 10 CFR 21.21(d)(4), ESI ls presenting the required Information as follows:

(i) Name and address of the Individual or Individuals informing the Commission.

Signal Converter Transmitter, PIN SCTl4-20MA/4-20MA/24DCI-LIM-TA[DCM].

(Iii) Identification of the firm supplying the basic component which fails to comply or contains a defect.

Engine Systems Inc. (ES/)

(iv) Nature of the defect or failure to comply and the safety hazard which Is created or could be created by such defect of failure to comply.

A power inverter transformer, Internal to the signal oonverter transmitter, failed shorted *. The transformer failure adversely affected.other circuit board mounted *components which prevented the device from functioning properly.

  • The signal converter transmitter ls a component of a turbine control panel. Within the panel, the
  • transmitter Is used to sense the customers remote speed setpoint 4-20 mA Input signal and convert the signal to an isolated 4-20 mA output signal which is transmitted to the turbine control.

Since the signal converter transmits the customer's remote speed setpafnt Input to the turbine control, operabl/ity of the device is critical to operation of the RCIC turbine control system. Therefore, a failure of the signal converter would adversely affect the RCIC turbine control system and thus may affect the safe shutdown of the reactor. *

2of2 (vii) The corrective action which has been, Is being, or will be taken; the name of the lndlvldual or organization responsible for the action; and the length of time that has been or will be taken to complete the action.

For Cooper Nuclear:

The failed component has been removed and replaced with a spare transmitter from a dffferent batch. No further action ls necessary.

ForESI:

The previous design transformer (used in the failed transformer) was discontinued by transformer manufacturer in 2016 which required the signal converter transmitter manufacturer to source a new transformer. The new transformer has the same functionality with a slightly dffferent form factor which minimizes the potential for common cause failure with the original style transformer.

Therefore. no additional actions are required since a different transformer ls In current use. ES/
