Dry cooling capability allows siting in locations without a source of cooling water. If the reactor is to become part of a hydrogen economy , the coolant outlet temperature of 850°C would allow the sulfur iodine cycle to be used which directly converts thermal energy into hydrogen (without electric or other intermediate steps) with an overall ...

In events where the reactor coolant pressure boundary remains intact, the Isolation Condenser System (ICS) is used to remove decay heat from the reactor and transfer it outside containment. The ICS system is a closed loop system that connects the reactor pressure vessel to a heat exchanger located in the upper elevation of the reactor building.
core coolant inlet: 307.5 core coolant outlet: 320 Equivalent core diameter, m — Active core height, mm: 3600 Outer diameter of fuel rods, mm: 13.16 Number of fuel rods in assembly: 311 Number of fuel assemblies 151 Uranium loading, tons - Average uranium enrichment, % 4.22 Average fuel burnup, MW · day / kg: 30
This also increases the capital cost and complexity of a PWR power plant. The high temperature water coolant with boric acid dissolved in it is corrosive to carbon steel (but not stainless steel); this can cause radioactive corrosion products to circulate in the primary coolant loop. This not only limits the lifetime of the reactor, but the ...

From January 2008 to December 2012, if you bought shares in companies when John B. McCoy joined the board, and sold them when he left, you would have a -19.1 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The difference between the heat of steam per unit mass at the inlet to the turbine and the heat of steam per unit mass at the outlet from the turbine represents the heat which is converted to mechanical power. Therefore, the more the conversion of heat per pound or kilogram of steam to mechanical power in the turbine, the better is its ...
