Saturable reactor; P/N 8408218-ESI PURPOSE:
This interim report is issued because Engine Systems, Inc. (ESI) has not able to complete an evaluation of an identified deviation within the 60-day requirement of 10CFR21.21. The evaluation is expected to be completed no later than March 22, 2019.
SUMMARY
ESI was notified on December 6, 2018 of a potential issue with saturable reactors (also referred to as magnetic amplifiers) supplied to Monticello Nuclear Generating Plant. ESI provided the reactors as like-for-like replacements for the existing magnetics of the original Vickers voltage regulator and static exciter. During system testing performed by Monticello at another vendor facility, issues with the static excitation system were identified which prevented proper control of the generator field current. Troubleshooting identified several potential causes and ESI believes there may be a potential deficiency in the saturable reactor, P/N 8408218-ESI.
This component is integral to operability of the Vickers style voltage regulator and static exciter systems used on many emergency diesel generator sets in the nuclear industry. A deficiency in the reactor would adversely affect the ability to control generator output voltage and therefore adversely affect emergency diesel generator set performance.
ESI is in the process of performing additional testing and analysis at the transformer manufacturer's facility to determine if a deficiency exists in this component. ESI is unable to complete an evaluation within the 60-day requirement.
EXTENT OF CONDITION / INTERIM CONTAINMENT ESI has supplied the reactor to the customers listed below. To ESl's knowledge, none of the components have been installed. In conjunction with submittal of this interim Part 21 report, ESI is notifying each of the customers and advising not to install the reactors until the evaluation is complete. ESI will also withhold shipment of any reactors until the evaluation is complete.
