Revision 17 2 of 3 Item Design and Performance Characteristics Main Steam Supply Piping and valves including branch lines System between the up to first valve in branch line First Weld outside the Safety Class 2, Seismic Category I Impingement Wall up to and including the Third Isolation Valve (Section 10.3)

Main Steam Supply Piping and valves: ANSI B31.1 or as System Downstream of designated in Table 3.2-1, Item XXXII the Third Isolation (Section 10.3)

Condenser Twin-shell, single-pass 616,750 ft 2 surface (Section 10.4.1) area, 27°F tube rise, equalizing ducts between steam sections and hotwell sections Condenser Air Two half-capacity air removal pumps for Removal System initial shell-side air removal; two (Section 10.4.2) full-capacity steam jet air ejectors for maintaining vacuum. Steam and noncondensibles go to the radwaste off gas system for the air ejectors and through charcoal filters to the atmosphere for the air removal pump. Piping and valves: ANSI B31.1 7 Turbine Gland Sealing Steam supplied from the steam seal System (Section 10.4.3) evaporator. Noncondensibles go to condenser. Piping and valves either ANSI B3l.l or General Electric's standard that parallels ANSI B31.1 7Turbine Bypass System Flow capacity equal to

9.5 percent

of the (Section 10.4.4) reactor design steam flow. Piping and valves up to but not including bypass valves: ANSI B31.1 and ANSI B31.1 downstream of the bypass valves. Bypass valves are as designated in Table 3.2-1, Item XXXII RBS USAR TABLE 10.1-1 (Continued) 3 of 3 August 1987 Item Design and Performance Characteristics Circulating Water Four 25-percent capacity circulating System (Section 10.4.5) water pumps, 4 multicell water cooling towers, and a fabricated-steel piping system Condensate Demineralizer a. Two trains each of 5 ion exchangers, System (Section 10.4.6) with 8 ion exchangers normally operating, external cleaning, and regeneration facilities, acid and caustic dilution systems, and waste recovery system b. Piping: ANSI B31.1 Pressure vessels: ASME Section VIII Condensate and Feedwater a. Three half-capacity motor-driven con-System (Section 10.4.7) densate pumps, 2 full-capacity air ejector intercondensers, 1 full-cap-acity steam seal condenser, 5 stages of low-pressure regenerative feed-water heaters including 2 separate drain coolers all divided into 2 strings of half-capacity heaters, 3 one-third capacity, motor-driven through step-up gear reactor feed pumps and 1 stage of 2 half-capacity high-pressure feedwater heaters

b. Piping and valves from the hotwell up to but not including the feed-water shutoff valve outside: the containment structure: ANSI B31.1.

Piping and valves from the first containment isolation valve to the reactor: ASME Section III, Code Class l. Feedwater heaters: ASME Section VIII. Feedwater shutoff valve and piping up to but not including containment isolation valves: ASME Section III, Code Class 2
