| Title | Alternative Report for Non-Declared Emergency Condition in Accordance with Nureg-1022 |
| Event Description | On July 7, 2006, at 1445 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.498225e-4 months <br /> with Watts Bar Unit 1 at 100% power, operations were underway to prepare to sluice resin to the spent resin storage tank. Due to a suspected valve alignment anomaly, approximately 60 gpm from the CVCS volume control tank transferred thru the cation vessel to the tritiated drain collector tank. This is considered identified leakage in accordance with EAL 2.6 RCS Leakage greater than 25 gpm.
This condition was immediately corrected within about 3.5 minutes but could have met the conditions for a NOUE had the event continued. Accordingly a NOUE was not declared, but this NRC ENS notification is being made in accordance with NUREG-1022 as an acceptable alternative to the immediate notification requirement of 50.72(a)(1)(i). The licensee informed the NRC Resident Inspector. |
