In PWRs - a different LWR system - control rods are withdrawn from the core, and the control is acheived with soluble B-10 in the coolant (which is buffered with LiOH) to maintain a pH above 6.9 or perhaps closer to 7.1 - 7.4 for purposes of minimizing the accumulation of crud (metal corrosion products) on the fuel.
Rhetorical patterns have an additional function of helping writers to organize information in ways their readers can understand easily (425). Another term for these patterns is topoi (commonplaces). Many of these topoi are useful in numerous situations.
Discourse will be discussed here with two different meanings. The ï¬ rst meaning is the manner in which the information is organized. In the formal reg-ister of English, the pattern is to get straight to the point.30 In casual register, the pattern is to go around and around and ï¬ nally get to the point.
