## Description

On February 10, 2015, the NRC issued a Notice of Violation to Dominion Nuclear Connecticut, Inc. for a Severity Level III violation of 10 CFR 50.59, "Changes, Tests, and Experiments" involving the failure to obtain a license amendment pursuant to 10 CFR 50.90, prior to implementing a change that resulted in more than a minimal increase in the likelihood of occurrence of a malfunction of a Structures, Systems and Components (SSC) important to safety previously evaluated in the Updated Final Safety Analysis Report (UFSAR). Specifically, Dominion allowed a design change to the offsite power system (removal of the severe line outage detection system (SLOD), a system described in the UFSAR), and failed to conduct a written evaluation or provide a basis for the determination that the change did not require a license amendment in accordance with 10 CFR 50.59 (c)(2).
