1. Introduction and General Description of the Plant AP1000 Design Control Document CHAPTER 1 INTRODUCTION AND GENERAL DESCRIPTION OF THE PLANT 1.1 Introduction This Design Control Document (DCD) for the Westinghouse AP1000 simplified passive advanced light water reactor plant is incorporated by reference into the Design Certification Rule for the AP1000 design (Section II.A) of Appendix D to 10 CFR Part 52. Revision 16 to the DCD is submitted to the NRC for review and approval application for an amendment to the Design Certification Rule for the AP1000. 1.1.1 Plant Location The AP1000 is a standardized plant that is to be placed on a site with parameters described in Chapter 2, Site Characteristics. The site parameters relate to the seismology, hydrology, meteorology, geology, heat sink, and other site-related aspects. 1.1.2 Containment Type The containment building is a freestanding, cylindrical, steel containment vessel with elliptical upper and lower heads. It is surrounded by a seismic Category I reinforced concrete shield building. The containment vessel is an integral part of the passive containment cooling system. The vessel provides the safety-related interface with the ultimate heat sink, which is the surrounding atmosphere. Westinghouse is responsible, along with their contractor team members, for the design of the containment. 1.1.3 Reactor Type The nuclear steam supply system (NSSS) for the AP 1000 is a Westinghouse-designed pressurized water reactor. 1.1.4 Power Output The plants net producible electrical power to the grid is
