SUMMARY

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.

The transmitter includes a limiting function where If the Input signal is below 4 mA, the minimum output Is limited to 2. 7 mA and If the 'Input signal is above 20 mA, the maximum output is limited to 21.3 mA. 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. *
