"Automatic Reactor Trip due to low Steam Generator levels. All systems responded normally. Plant is stable at NOT/NOP [normal operating temperature and pressure] in Mode 3. Emergency Feedwater system actuated as designed due to reactor trip."
Lowest Steam Generator level reached was just below the trip setpoint of 25%. Low level caused by trip of one of two Main Feed Pumps. All control rods fully inserted. No primary or secondary relief valves lifted. The electrical system is stable and the EDG's remain in standby. Decay heat is being removed via steam dumps.

On November 1, 2003, the plant was performing testing on the Control Room Envelope for Unfiltered In-Leakage Tracer gas Test. During this test the control room ventilation is set up to simulate system line up following an F, A, or Z signal. This dual pressurization line up consists of both control room emergency filtration (CREF) fans running with the normal and one of two remote air intakes isolated. This line up caused a low-flow condition to occur on both trains of CREF, rendering both trains of CREF to become inoperable. The inoperability of the CREF is due to losing the permissive to allow the heaters located in each of the fresh air ducts to the emergency filters to energize. These heaters reduce the relative humidity of air entering the emergency filters to 70%. Without the heaters the 30-day dose limits to control room personnel of GDC 19 of 10CFR50, Appendix A could be exceeded during a Design Basis Accident.
The isolation of a single remote air intake is a condition allowed under technical specification 3.3.7.1 and is also required for certain radiological and HAZMAT conditions. During an FAZ with an isolated remote air intake both trains of CREF will become inoperable until one train is shutdown.
Once both trains of CREF were inoperable the plant entered LCO 3.0.3. per technical specification 3.7.3. At 1728 the plant opened the isolation valves for the second remote air intake and the low-flow condition cleared for one train of CREF and LCO 3.0.3 was exited. The plant is currently in a 7 day LCO to shutdown for having one train of CREF inoperable per 3.7.3.
The NRC Resident Inspector was notified. |

The National Weather Service was unable to activate the Tone Alert Radios. The allowable out of service time was exceeded. The Tone Alert Radios were out of service for greater than one hour. In accordance with site procedures, this is a major loss of notification capability.
Oswego County reported that the Tone Alert Radios were returned to service.
