The ABB Combustion Engineering System 80+

1. recommendations by the U.S. utility industry in the Electric Power Res arch Institute, EPRI, ALWR Utility Requirements Document, URD
2. changes mandated by the U.S. Nuclear Regulatory Commission
3. changes desired by ABB-CE and the System 80+ Executive Advisory Commit ee based on plant operating experience

The System 80+ is a 1300 Mwe advanced pressurized water reactor. Like previous ABB-CE reactors, the System 80+ reactor coolant system has a two loop configuration, a major feature that has distinguished CE designed units. Like other ALWRs, improved safety performance and operability are achieved, owing to sophisticated design features. Another interesting feature of System 80+ is that it can run with Plutonium fuel, which could be a very useful mean to dispose the Weapon Graded Plutonium from dismantled nuclear warheads

The System 80+ standard Safety Analysis Report, SAR, called CES-SAR-DC, is complete and includes 18 volumes. In late 1991, the NRC completed its initial reviews, formally issuring over 1500 questions, all of which have been answered. The System 80+ is expected to receive a Final Design Certification by 1995. According to ABB-CE, the proven viability of System 80+ is significantly enhanced by the fact that four advanced System 80 nuclear steam supply systems are now under construction at Yonggwang and Ulchin in the Republic of Korea. Some of the System 80+ design features are included in these plants, scheduled to start commercial operation between March 1995 and June 1999. With over $50 million and 1 milliton engineering hours already invested in developement and design certification of System 80+, ABB-CE is preparing to embark on the next phase, first of a-kind engineering.
