SUMMARY

On June 5, 2019, Engine Systems Inc. (ESI) issued interim report 10CFR21-0125-INT, rev.O regarding an identified deviation for which ESI was unable to complete an evaluation within the 60-day requirement. Per the interim report, ESI committed to complete the evaluation by July 31, 2019. The evaluation is now complete and the deviation is determined to be reportable in accordance with 10CFR Part 21.

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

(i) Name and address of the individual or individuals informing the Commission.

John Kriesel Dan Roberts Engineering Manager Quality Manager Engine Systems Inc. Engine Systems Inc.

175 Freight Rd. 175 Freight Rd.

Rocky Mount, NC 27804 Rocky Mount, NC 27804 (ii) Identification of the basic component supplied within the United States which fails to comply or contains a defect.

Signal Converter Transmitter, PIN SCT/4-20MAl4-20MAl24DCI-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 converter transmitter, failed shorted. The transformer failure adversely affected other circuit board mounted components which prevented the device from functioning properly.

The signal converter transmitter is a component of a turbine control panel. Within the panel, the transmitter is used to sense the customer's 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 setpoint input to the turbine control, operability 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.

(v) The date on which the information of such defect or failure to comply was obtained.

April 6, 2018 (vi) In the case of a basic component which contains a defect or fails to comply, the number and location of these components in use at, supplied for, being supplied for, or may be supplied for, manufactured, or being manufactured for one or more facilities or activities subject to the regulations in this part.

Notes: (1) The signal converter was installed in a control panel assembly PIN 8001553-01 (qty 1 per panel).

(2) This is the failed device; therefore, no other suspect devices are installed in safety-related service.
