The Bureau of Reclamation's new Flatiron Dispatching Headquarters guides the flow of electricity and water from 11 power planta with installed capacity of 288,300 kw ond 16 reservoirs ;'whh storage capacity of 3,286,000 acre feet in Colorado and Wyoming. Its 17* * man crew dispatches power over a 2500* mite network of high-voltage transmis sion lines to 130 wholesale customers Water Wheel at Hydro Station .Disintegrates One of two horizontal-shaft 450-rpm water wheets driving e 30,000-kw gen erator flew apart at Pacific Gas A Elec tric's Bucks Creek hydro station on the Feather River. Of the 19-bncket wheel, one five-bucket piece, weighing 2% tons, hurtled through tho nation roof and landed on a hill 70 ft away. Another, with three buckets, hit the crane rail and fell into e atorege area. A third, with ten buckets, dropped Into the pit. The 19th bucket has not been found. Cause of the accident Is unknown, but and feeds water into canals serving more than o million aerea of form land. The Flatiron'operation, known offi cially os headquarters for the Upper Platte System, ties together the water and power functions of the ColoradoBig Thompson and the North Platte reclamation projects. Power generated on the system totaled 732,000,000 kwh In 19S2. Depending on water inflow conditions, this year's generation will be from three-quarters to one billion kwh. The system is designed for integrated operation with the Public Service Co of Colorado, and two connections now ex ist between the utility and the bureau lines. A third connection will be mado this fall when the Flatiron power plant one piece of the disk shows signs of a crack and Internal rusting which went undetected since the wheel was installed in 1928. Best guess is that one bucket let go and the resulting unbatonce vi brated the wheel to destruction. Inves tigation may sideline the unit for up to a year, the company estimates. A second 30,000-kw unit was not offectod and remains in operation. Rucks Creek has a static head of 2562 ft, high est in the country. For eomlnf events see page 242 is finished and put in operation. Operating problems are complicated, because all of the power generatkm is ot the western end of the transmission lines where water flows from the Roek-a iea onto the plains. These Urge trans mission distances coupled with light loods cause tremendous charging cur-rent to develop on the high-tension lines.Thus 115,000 volta placed on the lines at the generating end of the system eftra': rises to 135,000 or 140,000 volts at the* end of the tranamiasion lines. To correct thU condition, which caused homo eleotricel appliances to burn out If not controlled, four ahant reactors and a 40,000 kw condenser were Instolled ot the eastern end of the lines ' Industrial Forum Predicts Commercial Atomic Power At a recent press conference, *i* directors of Atomle Industrial Fonita, Inc, agreed that commercial general!00 of electric power by breeder reactors W likely In the next ten year*.
