FROM HINKLEY . . . TO SIZEWELL

OSTI ID:4840791
Comparisons of design and costs of the Hinkley and Sizewell power stations are presented. Since the Hinkley station is the older of the two (under construction), it is shown how technology advanced from the mistakes made in the design features of this station. The most important contributions to the rather dramatic cost reduction (the estimate for the capital cost of Sizewell per kilowatt installed is some 30% less than the expected cost of Hinkley) are: an increase in the station output brought about partly by an increase in the coolant gas pressure, allowing a reduction in the number of primary loops from six to four; the combination of two reactors into one major building with a common charge floor; positioning of the circulators within the boilers, which allows a simple main duct layout; the use of two standard turbines instead of six; attention to design details; and know how.
