Background
At 3:44 p.m.on April 28, 1982, one of two operating Steam Generator feedwater pumes at Salem Unit 2 tripped while the plant was operating at 100% power.
Subsequent examination by the licensee determined that the isolation valve to the high back pressure switch on the pump's turbine exhaust had been shut and the vent valve in the line opened to atmospheric pressure causing the Feedwater Pump turbine protective control circuitry ci ':,
to; sense a loss of condenser vacuum causing an automatic pump trip. A total of four valves were manipulated and each valve was found in either the full open (vent valves) or full closed (back pressure switch) position which required approximately four 360* revolutions of each valve to
~_.
obtain those positions.
No manipulation of the valves had been authorized and the licensee postulated that the act was intentional and most probably related to an ongoing labor contract dispute with the International Brotherhood of Electrical Workers.

The valves are located in g g e/N a t M7, PSE&G, on April the No. 21 Steam Generator feed pump and turbine panel 362 located on the 100 foot elevation of the turbine buildino,shich is an unrestricted access area (Exhibit 1 pertains).

The manipulated valves are standard " Whitey" valves and are clearly marked as PD-2239, Turbine Exhaust low Vacuum Alarm and PD-2238, Turbine Exhaust cow Vacuum Trip (Exhibit 4 pertains).
The rear back pressure switch valves had been maaipulated closed on each line and the front This caused the facing vent valves had been manipulated full open.
It was also protective circuitry to sense a loss of condenser vacuum.
noted during the examination that the feedwater pump's manual trip switch is located approximately 25 feet from the feed pump and turbine panel 362 which provides a more direct method of tripping the feedwater pumps if desired.
This switch was not manipulated in this incident.
The four valves in cuestion were processed for latent fingerprints by the 1
reporting investigator; however, no identifiable latent prints could be obtained from the valves.

Individual B said he started the job with Individual A at approximately 1:00 p.m.
He said they worked on the transmitter for 0r7 ~

Review of Instrument Calibration Data On May 10, 1982 Mr. 6 *A m e
- r w W N c3provided the most recent calibration data on the. valves in question.
The records reflected the turbine exhaust low vacuum pressure trip switch was removed from the field on December 3, 1981 and a bench calibration was performed.
The switch was disassembled, cleaned and reinstalled in the field at that time.
i Tiie records also reflect that the turbine exhaust low vacuum alarm valves were adjusted and verified on the cor.iputer for the trip in normal po-
-y sitions on this same date.
No other maintenance or calibrations were j
recorded as authorized or performed since that time period.
He said these valves are not part of the safety system and as such are not incorporated into the regular surveillance activity.
