| The licensee entered and exited an Unusual Event due to a leak from the      |
| Chemical and Volume Control System (CVCS) that was caused by the lifting of  |
| a relief valve. During valve maintenance on a line tagged out as isolated,   |
| the opening of a valve caused pressure in the line to exceed that of a       |
| relief valve, causing flow to the Unit 1 Boric Acid Storage Tank (BAST). The |
| licensee is sampling the tank to ensure operability of the tank. The NRC     |
| resident inspector has been informed of this event by the licensee.          |
