Title

Licensee-Identified Violation

Description

The following violation of very low significance (Green) was identified by the licensee and is a violation of NRC requirements, which meets the criteria of Section 2.3 of the NRC Enforcement Policy for being dispositioned as an NCV. The licensee violated TS Section 3.3.9, Boron Dilution Protection System, when they failed to enter the LCO Conditions A and C, which required 1-hour actions to close non-borated water source isolation valves and to verify that shutdown margins were within their limits. Unit 1 entered LCO 3.0.3 due to not completing the required actions. Upon discovery, the licensee lowered the water volume in the volume control tank to clear the alarms and exit all the LCOs. This violation was not greater than green since the shutdown margin was verified within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and no significant change in reactivity occurred. The licensee entered this issue into the CAP as AR01101873 and has submitted LER 2010-002-00.
