UPDATE 3-PSEG N.J. Salem 1 reactor shut

By Scott DiSavino	
    April 30 (Reuters) - Public Service Enterprise Group Inc
 said its 1,174-megawatt Unit 1 at the Salem nuclear
power plant in New Jersey experienced an automatic reactor
shutdown on Monday morning.	
    The plant is stable and the cause of the trip is under
investigation, PSEG spokesman Joseph Delmar said. "A return to
service is unavailable at this time." 	
    The U.S. Nuclear Regulatory Commission (NRC) spokesman, Neil
Sheehan, told Reuters earlier that the unit had experienced an
inadvertent safety injection (SI) and reactor trip during
reactor protection system testing.	
    An Unusual Event, which was declared due to multiple fire
alarms involving the containment building, was terminated after
operators determined that there was no fire. An unusual event is
the lowest of the NRC's four emergency classifications.	
    Electricity traders guessed the unit could be down for about
a week.	
    Meanwhile, Unit 2 at the Salem nuclear power plant was not
impacted and continued to remain at full power.

              originally designed for two reactors but as       	
              costs rose the utility and state decided not to   	
              pursue the second unit. The state also believed   	
              there was not enough demand to warrant the    	
              second unit
