13-4. A 7-ft-high cylindrical pressurized-water reactor core contains 25,000 cylindrical fuel elements, 0.34 in. OD, containing UO, cylindrical pellets of 0.3 in. diameter each. The heat generated in the fuel is 180 Mw(t); 20 x 106 lbm/hr of coolant enters the core channels uniformly at 500°F. The heat-transfer coef- ficient is 5000 Btu/hr ft² °F. Neglecting the extrapolation lengths, find the minimum water pressure necessary to ensure that no boiling occurs anywhere in the core.
