v t e ENS Event
18:06 Jun 22, 2015
Title	Sodium Hydroxide Below Technical Specification Required Concentration
Event Description	At 1406 [EDT] on 6/22/15, the chemistry sample results for the Salem Unit 1 Containment Spray Additive tank were below the minimum Technical Specification requirement for NaOH [Sodium Hydroxide] concentration. The Containment Spray Additive tank was declared inoperable at that time in accordance with Technical Specification 3.6.2.2.a. Based on the fact that there is no redundant equipment for the Containment Spray Additive tank, this condition could have prevented this Safety System from Controlling the Release of Radioactive Material and Mitigating the consequences of an accident. This event is being reported under the requirements of 10 CFR 50.72(b)(3)(v)(C) and (D) as 'Any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of systems that are needed to Control the Release of Radioactive Material and Mitigate the Consequences of an Accident.' Actions are being taken to restore the NaOH concentration to within the Technical Specification limits. The Licensee has notified the NRC Resident. No one was injured as a result of the event. The licensee will notify the Lower Alloways Township.
