The important features of the PWR core are shown in Figure 19.12, which, although taken from three different reactors, represents the typical Westinghouse design. A typical core contains 40 000 fuel rods (a) in 193 assemblies, each with space for 208 fuel pins... 

To minimize the core damage frequency, the mPower, NuScale, and Westinghouse designs have the following safety features ... 

The Westinghouse design features, as given in the following publically available documents Buongiorno, USNRC (http //www.nrc.gov/reactors/advanced.html), and Westinghouse publically available information forms the basis for the following description. 

The 300 MW(e) pressurized water reactor of ANSALDO-NIRA is based on WESTINGHOUSE design and uses the "Enrico Fermi" nuclear power plant sited at Trlno Vercelese in Italy as reference plant.

Although the Siemens Westinghouse design of tubular SOFC is by far the best-known and most developed, two other types of tubular SOFCs, shown in Figure 7-9 illustrate ways in which the cells are interconnected. Numerous other designs have been proposed, but are no longer pursued (14).

The cost of any proposed measure that would be required to control a risk needs to be assessed. Appendix IB of Reference 8.2 provides the Westinghouse design engineers estimates ofthe cost for most of the potential additional design features in US dollars. These are shown in order of increasing cost in the table below. Also shown are the costs in UK pounds, assuming an exchange rate of 1.5 to 1. 

The dose from direct radiation needs also to be added. Section 12.4.2 of the EDCD (Reference 12.1) states that the direct radiation dose at the site boundary is negligible. To provide an estimate, the doses experienced from the closest comparable design currently in operation in the UK have been used, i.e., the Sizewell B PWR, which is based on an older Westinghouse design. The direct shine dose at the Sizewell B perimeter fence was 4 pSv in 2007, taken from Appendix 4 of Radioactivity in Food and the Environment Report, 2007 (Reference 12.7). 

In the tubular SOFC, as illustrated by the Siemens Westinghouse design shown in Fig. 13 [86], the cell components are deposited in the form of thin layers on a doped lanthanum manganite cathode tube [80, 87]. The cathode tube (2.2 cm diameter,...
