EPR FINAL SAFETY ANALYSIS REPORT

1.7 Drawings and Other Detailed Information

1.7.1 Electrical and Instrumentation and Control Drawings

Table 1.7-1—I&C Functional and Electrical One Line Diagrams, contains a list of
instrumentation and control functional diagrams and electrical one-line diagrams.
The legends for electrical and instrumentation and control functional diagrams are
provided in Figure 8.3-1—Electrical Single Line Drawing Legend and Figure 7.1-1—
Chapter 7 Symbol Legend, respectively.

A COL applicant that references the U.S. EPR design certification will list additional
site specific instrumentation and control functional diagrams and electrical one-line
diagrams included in the COL FSAR in Table 1.7-1 and supplement the figure legends,
if applicable.

1.7.2 Piping and Instrumentation Diagrams

Where appropriate, piping and instrumentation diagrams (P&ID) are provided

throughout the FSAR. The P&IDs provide needed design information or demonstrate
how the subject systems and components perform their associated safety function(s).
Valve position indications shown on these figures do not represent a specific
operational state. A list of systems and their corresponding FSAR figure numbers is
provided in Table 1.7-2—U.S. EPR System Designators and System Diagrams. The
U.S. EPR subscribes to the Kraftwerks Kennzeichen System (KKS) for coding and
nomenclature of structures, systems, and components. The KKS designators are also
used in the P&IDs. Figures appear at the end of the respective text section. The P&ID
legend is provided in Figure 1.7-1. The P&ID legend provides an explanation of U.S.
EPR symbols and characters used in these FSAR figures.

For continuation labels on the figures, the sheet number in the label refers to the
native file name shown in the lower right corner of the figures, not to the sheet
number listed above the figure with the figure title. The native file name consists of
three parts—the system designation (normally the KKS system name), followed by the
native sheet number, followed by an indication of either Tier 1 or Tier 2. For example,
native file name FAL02T1 refers to the fuel pool purification system (FAL), native
sheet 02, for Tier 1. If a continuation label refers to a figure of a different system, it is
identified in the continuation label, with the system designation preceding the native
sheet number of the continuation figure. If the continuation is on a native sheet
number within the same system, the system designation on the continuation label is
not included.

A COL applicant that references the U.S. EPR design certification will list additional
site specific P&IDs included in the COL FSAR in Table 1.7-2 and supplement the
figure legend, if applicable.
