Status report on anticipated transients without scram for General Electric Reactors

The review of the GE ATWS analyses included the anticipated transients expected to occur, the initial conditions and system parameter assumed in the analyses, the reliability of systems, the analytical techniques, the results of analyses of ATWS events and the design of the Reactor Protection System. Using the requirements of WASH-1270 as a guideline, the staff reviewed each relevant aspect of the GE model and analysis. The discussion of anticipated transients is presented, and the initial conditions, system parameters and operating systems assumed in the analyses of these transients are also discussed. The analytical techniques and computer programs are reviewed
