Title	Feedwater Regulating Valve Issue Forces Initiation of Technical Specification Shutdown
Event Description	At 1603 Salem Unit 1 commenced a down power to comply with Technical Specifications. Tech. Spec. 3.0.3. was entered at 1505 when it was determined that the feed regulation valve for the 14 Steam generator (14BF19) was bound at approximately 71% open. This valve is required to close on a feedwater isolation signal. Currently the reactor is at 40% power and lowering with plans to stabilize at 25% prior to taking the unit off line (mode 3) by 2205 tonight. Unit 1 has no other tech spec equipment out of service. Unit 1 is in two additional shutdown Technical Specifications, both are related to the control room ventilation system which is shared with Unit 2. Unit 2 is in a scheduled refueling outage and one of the Unit 2 emergency intake dampers is disabled (T.S. 3.7.6.1.a). This is a 7 day LCO that expires on 10/22/03. Additionally Unit 2's emergency filtration system is out of service for planned maintenance (T.S 3.7.6.1.a). This is a 30 day LCO that expires on 11/13/03. All other systems on Unit 1 are operating as expected for current plant conditions. The licensee notified the NRC Resident Inspector.
