Salem Unit 1 has initiated a unit shutdown … Salem Unit 1 has initiated a unit shutdown in accordance with TS (Technical Specification) Action Statement 3.4.6.2(b) for unidentified leakage greater than 1 gpm (gallon per minute) (Entered on 8/22/13 at 1029 EDT). TS 3.4.6.2 Action Statement (b) requires a reduction of leakage rate to within limits within 4 hrs. or be in at least Hot Standby within the following 6 hours. Initial investigation has indicated that the leakage source is from packing on Pressurizer Spray Valve 1PS1 located in the RCS (Reactor Coolant System) Pressurizer shroud area inside Containment. Unidentified leakage is currently indicating 4 gpm. NRC Resident (Inspector) has been notified. Manual isolation is in progress.</br>Additionally, TS Action Statement 3.6.1.4 Primary Containment Internal Pressure was entered at 1510 (EDT) for exceeding 0.3 psig. Action requires restoration of containment pressure to within specification in 1 hour or be in hot standby within the next 6 hours. Containment pressure was restored to less than 0.3 psig at 1647 (EDT) and TS 3.6.1.4 was exited. Peak containment pressure reached (was) 0.33 psig.</br>Location of leak: Unit 1 RCS (containment), Pressurizer, 1PS1 Pressurizer Spray Valve Packing</br>Time & date leak started: 1019 (EDT) on 08/22/2013</br>Leak rate: 4 gpm, T/S leak limits: 1 gpm</br>Last known coolant activity: Primary (DEI (Dose Equivalent Iodine)-microCuries/cc) 5.973E-5 microCuries/cc</br>Secondary (gbg (Gross Beta Gamma)-microcuries/cc) < LLD (Lower Limit of Detectability)</br>Was this leak a sudden or long-term development?
