CURRENT GENERATION REACTORS

15.2. PLANT LIFE EXTENSION The technical issues associated with plant ageing centre around the ageing of mechanical, electrical and materials ageing of plant components, particularly concretes and steels (Govaerts, 2001). The EC is funding a major research programme on this issue and a selection of some of the on-going projects is summarised below (Table 15.1). Utility practices for the safe […]

Sub-Channel Analysis

Sub-channel analysis is performed to determine the safety margin to boiling in peak rated channels in LWR assemblies. The flow and heat transfer distributions inside a fuel assembly can be analysed by sub-channel codes. The usual reason for analysis is to demonstrate compliance with the ‘Departure from Nucleate Boiling Ratio’ (or DNBR) requirements. The codes calculate the DNB from various […]
