. w ss.o a m.w MILLSTONE l' NIT NO. 3 FIRE LOOP FLOW TEST On July 9, 1984, Generation Fire Protection Engineerine conducted a water flow test of the 12 inch underground fire water loop at Millstone Unit No. 3.
The purpose of this flow test was to determine the water supply / pressure available, in order to provide a reference point for deternining epn/ psi throughout FP-III's underground loop.
The flow test was conducted utilizing two hydrants located within the northeast portion of the fire loop (North of 'Jaste Disposal Building & North of Maintenance Two 21" fire hoses (150' in length Shop). Please refer to the attached sketch.
5 each) were connected to the flow hydrant. Attached to each hose was a standard Underwriters Laboratories (UL) playpipe (1 3/4" tip).
Static and residual pres-sure readings were obtained using a calibrated pressure gage installed within the flow path.
The rate of flow in gallons per ninute (CPM) was determined by measurine, the velocity pressure of each strea, utilizing a calibrated pitet cao,e.
The test findings were as follows:
Static Pressure 124 psi Residual Pressure 119 psi Hose #1 Pitot Reading 36 psi or 546 gpm Hose #2 Pitot Reading 40 psi or 575 gpm It was concluded that this remote hydrant is capable of delivering 1121 gem at a pressure of 119 psi.
