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.
The first commercial APR-1400 reactors at Shin Kori were approved in September 2007, [12] with construction starting in October 2008 (Unit 3) and August 2009 (Unit 4). [3] [13] [14] Shin Kori-3 was initially scheduled to commence operation by the end of 2013, but the schedules for both Units 3 & 4 were delayed by approximately one year to replace safety-related control cabling, which had ...
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 ...
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 ...
An inlet air cooling system installed in a desert-dry area to increase turbine power output. Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation.
A mortgage point could cost 1% of your mortgage amount, which means about $5,000 on a $500,000 home loan, with each point lowering your interest rate by about 0.25%, depending on your lender and loan.
Just before the College Football Playoff kicks off, Dan Wetzel, Ross Dellenger, and SI's Forde provide a final preview of the 12-team bracket. They discuss the potential for five to six different ...
