Sodium and NaK - Reactor Coolant - Nuclear Power

WebThey use molten sodium or a eutectic sodium-potassium alloy (NaK) as the reactor coolant. Melting and boiling points of sodium and NaK are: Sodium-cooled Fast Reactor (SFR). NaK containing 40% to 90% potassium by weight is liquid at room temperature. The eutectic mixture consists of 77% potassium and 23% sodium. Web26 aug. 2010 · The melting temperature for this sequence is calculated as follows. Step 1: Read the sequence from 5′ end to 3′ end and add up the DNA strength parameter given in Table 1 for each dinucleotide step, moving one base at a time as: GA = 8, AC = 10, CG = 10, GA = 8, AC = 10, CA = 7 and so on. (For the given sequence of 15 base pairs, 14 ... focused solutions hy

Why does magnesium have a higher melting point than sodium?

WebThe positive ions attract the negatively charged electrons so the bond is very strong.Magnesium has a higher melting point because magnesium ions are Mg 2+ and … http://www.nonmet.mat.ethz.ch/education/courses/Materialwissenschaft_1/Downloads_HS_2007/slides_chapter_3.pdf WebDuratron® PAI.
