ABB Combustion Engineering began the development of the System 80+ standardized nuclear plant design in 1986. System 80+ is a 1350 MWe evolutionary, Advanced Light Water Reactor (ALWR) nuclear plant employing a pressurized water reactor. As the design information was produced it was submitted to the U.S. Nuclear Regulatory Commission (NRC) for approval under the NRC`s new licensing regulations for standardized designs, 10CFR52. The new NRC regulations require that standard designs for future nuclear plants must address safety issues that were not specifically required for the current generation of nuclear plants operating in the United States. The new requirements are grouped into three categories: (1) performance of a Probabilistic Risk Assessment (PRA) and consideration of design improvements based upon insights from the PRA, (2) resolution of the NRC`s unresolved and generic safety issues, and (3) consideration of severe accidents (involving core melt) in the design of the plant. The new NRC requirements, combined with feedback from utilities via the EPRI ALWR Utility Requirements Document (URD), resulted in substantial changes to ABB-CE`s earlier standard design, System 80, which is currently operating in the United States at the Palo Verde site and is under construction at two sites in the Republic of Korea. The new standard design, System 80+, has essentially completed NRC review. A Final Design Approval (FDA) is scheduled by the NRC in August 1994.
