STONE AND WEBSTER (SHAW GROUP) WAS CONTRACTED TO INSTALL PIPING INSIDE OF THE CONTAINMENT AREA OF THE SALEM/HOPE CREEK NUCLEAR FACILITY.  THIS PROJECT WAS TO BE COMPLETED DURING SHUTDOWN.  HOWEVER, IN ORDER TO MAKE SURE THE PROJECT WAS ON SCHEDULE, REBAR HAD TO BE MAPPED WHILE THE REACTOR WAS UP.  THEY HAD TO DO THIS FAST, SAFE AND ACCURATE.  AFTER PROVIDING DOCUMENTS AND MONTHS OF CORRESPONDENCE PROVING THAT GPR WAS NOT GOING TO SET OFF ANY SWITCHES INSIDE OF THE REACTOR, DIGITAL CONCRETE IMAGING WAS HIRED TO COMPLETE THE JOB.  THE PROJECT WAS SUCH A SUCCESS THAT DCI WAS HIRED BACK TO DO THE SECOND REACTOR AND OTHER SIMILAR SITES.
