TURBINE TRIP/REACTOR TRIP. ALL SYSTEMS OPERATED AS EXPECTED.
This notification is being made to report that Salem Unit 1 has experienced an automatic reactor trip. All rods fully inserted into the core. The reactor trip was caused by a main turbine trip. The cause of the main turbine trip is under investigation. Post trip, main feedwater to steam generators was isolated due to the feedwater air lock, which is expected on a reactor trip. The auxiliary feedwater system automatically started on low steam generator water levels, and this was also expected on a reactor trip. Auxiliary feedwater pumps "21," "22," and "23" all automatically started and fed the steam generators. The turbine-driven auxiliary feedwater pump, "23," has been shut down by procedure since the "21" and "22" motor-driven auxiliary feedwater pumps were maintaining adequate feedwater flow. Main feedwater restoration is in progress.
Salem Unit 1 is currently in Mode 3 (Hot Standby). Reactor coolant temperature is currently 547 degrees F, and plant pressure is 2235 psi. All emergency core cooling systems and all engineered safety feature systems are available. There are no shutdown technical specification limiting conditions for operation (LCO) in effect. There is one non-shutdown technical specification LCO in effect due to the power distribution monitoring system being inoperable. The system is functional, but post isolation testing will not be completed for some time. The only major secondary equipment unavailable is number one station air compressor, which is out of service for oil filter replacement. It is expected to be restored to service today. The emergency diesel generators are fully operable if needed, and the electrical grid is stable.
The licensee plans to notify the Lower Alloways Creek Township of this event. The NRC Resident Inspector was notified of this event by the licensee.

APPEARANCE THAT A TRISTATE INSPECTION AND CONSULTANTS RADIOGRAPHER EXCEEDED THE 5-REM ANNUAL LIMIT
The licensee is reporting this event due to the appearance that a radiographer exceeded the 5-rem limit for the year. The individual's dose (year to date) is 5,050 millirem.
The licensee's initial investigation indicates that the individual did not actually receive all of the indicated dose. Apparently, the individual routinely put his badge in his tool box at the end of the day, and the second shift crew used the individual's tool box without realizing that the badge was inside. Therefore, the badge received additional exposure during the course of the second shift. Apparently, the tool box was located in a vehicle which was parked inside the boundary ropes in a refinery lay-down area where the crew shoots weld coupons. It was reported that the second shift crew did not routinely use the individual's tool box, and there were no unusual doses with the individual's partner or with any of the other radiographers.
The radiographer whose badge is in question is being restricted from radiography work until the licensee's investigation has been completed. The licensee is waiting on letters from the radiographer whose badge is in question and from the radiographer who used the tool box containing the badge during the second shift.
The licensee plans to submit a written report within 30 days.
(Call the NRC operations officer for a licensee contact telephone number.)
