v t e ENS Event
05:24 Jul 8, 2014
Title	Unit 2 Spray Addition Declared Inoperable Due to Tank Indication Greater than 67%
Event Description	At 0024 CDT on 7/8/2014, Unit 2 Spray Addition was declared inoperable and LCO 3.6.7 (Spray Additive System) not being met, which resulted in a condition reportable pursuant to 10CFR50.72(b)(3)(v)(D). The inoperability was caused by Unit 2 Sodium Hydroxide Tank level indication greater than 67%, at 67.5%. This exceeds a current Prompt Operability Determination compensatory action requirement stating 'level shall be maintained no higher than 67%.' At 0104 CDT on 7/8/2014, Unit 2 Sodium Hydroxide Tank level was restored to an acceptable level, less than 67%. TSAC 3.6.7B was exited and LCO 3.6.7 met. The licensee informed the NRC Resident Inspector. * * RETRACTION PROVIDED BY BRADLEY DERINGTON TO JEFF ROTTON AT 1710 EDT ON 09/05/2014 * * * Point Beach is retracting EN# 50262 made on July 8, 2014 at 0628 CDT. The Operability Determination for this condition has been revised based upon engineering analysis. The event notification is being retracted based upon the subsequent Operability Determination revision that shows the NaOH Injection System was capable of performing its safety function at an observed Spray Additive Tank level of no higher than 77.2 percent. The licensee has notified the NRC Resident Inspector. Notified R3DO (Lipa).
