Experience in the Review of Utility Control Room Design Review and Safety Parameter Display System Programs

The NRC staff has reviewed the DCRDR Program Plans for a large fraction of the control rooms in nuclear power plants but has reviewed the Summary Reports of completed reviews for only a few control rooms. We have reviewed the SPDS Safety Analyses and Implementation Plans for about one-third of the SPDSs but have conducted no reviews of completed designs. Our observations, therefore, are based more on utility plans and programs that are in progress than on completed programs.
