The measured static pressure at Pump #3 outlet (primary subsurface supply pump) located near the North Portal on the North Portal Pad was measured by Title I11 A/E as 65 psi (CRWMS M&O 1999~). The pump is has a capacity of 600 gpm @ 39 PSIG (CRWMS-M&O 19989) 4.1.2 Pump # 3 is located near the portable tanks approximately 335 feet (scaled distance) from the North Portal Station O+OO as measured from the portable tanks closest to the portal to the North portal (CRWMS M&O 1998~). 4.1.3 The required minimum pressure and flow rate at the fire hose station nozzle is 30 psi @ 100 gpm (CRWMS M&O 1998a, p. 24). 4.1.4 The pressure loss for smooth walled 6-inch diameter steel pipe with an assumed flow of 275 gpm (Assumption 4.3.5) = 0.00234 psi/ft ofwater pipe(CRWMS M&O 1994, Attachment I1 p. 7 of 13,) 4.1.5 Distance fiom Station O+OO to grade break Station 28-tO4.323 & 9200.5 ft (CRWMS-M&O 1996, p. 27) Distance from Station O+OO to Pump Station 40+00.00 z 13 123 ft (Assumption 4.3.3) Distance from Station O+OO to grade break Station 56+54.323 E 18550 ft (CRWMS
The Yucca Mountain Performance Confirmation program consists of tests, monitoring activities, experiments, and analyses to evaluate the adequacy of assumptions, data, and analyses that form the basis of the conceptual and numerical models of flow and transport associated with a proposed radioactive waste repository at Yucca Mountain, Nevada. The Performance Confirmation program uses an eight-stage risk-informed, performance-based approach. Selection of the Performance Confirmation activities (a parameter and a test method) for inclusion in the Performance Confirmation program was done using a risk-informed performance-based decision analysis. The result of this analysis and review was a Performance Confirmation base portfolio that consists of 20 activities. The 20 Performance Confirmation activities include geologic, hydrologic, and constructiodengineering testing. Several of the activities were initiated during site characterization and are ongoing. Others activities will commence during construction andor post emplacement and will continue until repository closure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
